Proposal 1. Election of Directors

Our certificate of incorporation and bylaws provide that our Board of Directors shall consist of no more than thirteen directors and not less than seven directors, provided that the majority of the Board consists of employee directors. The size of the Board may be changed from time-to-time by the resolution of the Board of Directors. There are currently thirteen members on our Board with six outside independent directors and seven employee directors.

Director Nominations

According to our bylaws and our Governance Principles, director candidates are nominated by the Board of Directors based on recommendations of the Governance and Corporate Citizenship Committee of the Board. The Governance and Corporate Citizenship Committee's recommendations for employee director candidates take into account the recommendations of the Chairman and Chief Executive Officer whose recommendations are developed based on nominations from employee stockholders. The Governance and Corporate Citizenship Committee considers the Chairman and the Chief Executive Officer's recommendations, its own assessment of the needs of the company and the overall employee and independent mix of the Board in making recommendations to the Board. The Governance and Corporate Citizenship Committee recommended to the Board that each of Jacqueline C. Hinman, Gregory T. McIntyre and Thomas L. Pennella be nominated for election as employee directors as part of the 2016 nomination slate and that Malcolm Brinded, Scott Kleinman and Antoine G. Munfakh be nominated for election as independent directors as part of the 2016 nomination slate.

Messrs. Kleinman and Munfakh, who were appointed as directors in June 2015, were recommended to the Governance and Corporate Citizenship Committee and designated by AP VIII CH2 Holdings, L.P. ("AP VIII CH2"), an entity owned by investment funds affiliated with Apollo Global Management, LLC ("Apollo"), to serve as members of our Board of Directors pursuant to an Investor Rights Agreement, dated June 24, 2015, between us and AP VIII CH2. We entered into the Investor Rights Agreement with AP VIII CH2 in connection with AP VIII CH2's purchase of our Series A Preferred Stock in June 2015. Each of Mr. Munfakh and Mr. Kleinman is affiliated with Apollo. Additional information concerning the terms of the Investor Rights Agreement and AP VIII CH2's right to designate directors to our Board of Directors is available below in the "Certain Relationships and Related Transactions."

The director candidates will each serve a three-year term expiring in 2019 or until their earlier retirement, death, resignation or removal. In the event that any of the nominees should become unavailable to stand for election at the annual meeting, the proxy holders will vote for either (1) such other person, if any, as may be designated by our Board of Directors, in the place of any nominee who is unable to serve or (2) the balance of the nominees, leaving a vacancy. Alternatively, the Board may reduce the size of the Board. Our Board of Directors expects all of the nominees named below to be available for election. Incumbent directors will hold office until the annual meeting in the year their term expires and until their successors, if any, are elected and qualified, subject to the director's earlier death, retirement or removal.

Corporate Governance

Board of Directors

CH2M is governed by our Board of Directors. Our Board held a total of seventeen meetings in fiscal year 2015, five regularly scheduled and twelve special meetings. All directors attended 75 percent or more of the aggregate meetings of the Board and Committees of which they are members. CH2M does not have a policy regarding Board members attending the Annual Meeting of Stockholders. We had twelve Board members attend last year's Annual Meeting of Stockholders either in person or via telephone.

Corporate Governance Principles

CH2M is committed to best practices in corporate governance and maintains a business environment of uncompromising integrity.

We continue to implement this commitment through, among other things, our Governance Principles, practices and compliance with the relevant provisions of the Sarbanes-Oxley Act of 2002, Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, and other laws and regulations that regulate CH2M and our business. Our Board has formalized our standards of corporate governance in our published Governance Principles. Our Governance Principles, some of which are discussed below, are available on our website at http://ir.ch2m.com/corporate-governance. Our governance policies are reviewed annually by the Governance and Corporate Citizenship Committee of our Board to assure that they continue to advance the best interests of CH2M and our stockholders, and whether they comply with applicable laws and regulations.

Director Independence

There are currently thirteen members on our Board, six of whom are independent directors and seven of whom are employee directors. CH2M's common stock is not listed on a national securities exchange and, as a result, our directors are not subject to the independence requirements of a national stock exchange. In 2011, the Board adopted independence standards that are consistent with the independence tests under the corporate governance rules for listed companies of the New York Stock Exchange. The Governance and Corporate Citizenship Committee of the Board reviews our Board independence standards annually to confirm their appropriateness for the company. Under our Board's standards, a director is not independent if:

The director is, or has been within the last three years, an employee of CH2M, or any of the director's immediate family members is, or has been within the last three years, an executive officer of CH2M.

•

The director, or any immediate family member of the director, has received, during any twelve-month period within the last three years, more than $120,000 in director compensation from CH2M, other than director and committee fees, and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service).

•

(1) The director is a current partner or employee of a firm that is the internal or external auditor of the CH2M; (2) the director has an immediate family member who is a current partner of such a firm; (3) the director has an immediate family member who is a current employee of such a firm and who personally works on the CH2M audit; or (4) the director, or any immediate family member of the director, was within the last three years a partner or employee of such a firm and personally worked on the CH2M audit within that time.

•

The director, or any immediate family member of the director, is, or has been within the last three years, employed as an executive officer of another company where any of CH2M's executive officers at the same time serves or served on the other company's compensation committee.

CH2M 2016 Proxy Statement    11

•

The director is a current employee of, or any immediate family member of the director, is a current executive officer of a company that has made payments to, or received payments from, CH2M for property or services in an amount which, in any of the last three fiscal years, exceeded two percent (2%) of such other company's consolidated gross revenues or $1,000,000, whichever is greater.

Our outside independent directors include Malcolm Brinded, Scott Kleinman, Antoine Munfakh, Charles Holliday, Jr., Georgia Nelson and Barry Williams. The Board has made a determination that all these independent directors are "independent" under our independence standards. Because our Audit and Compensation Committees are comprised solely of our independent directors, all the members of those committees are independent pursuant to these guidelines.

Board Leadership Structure

Under our Board's Governance Principles, our Board has the ability to change its leadership structure in the best interest of CH2M at any point in time. Our Board is led by a Chairman elected annually by the directors. Ms. Hinman has served as Chairman of the Board of CH2M since September 2014.

Our Board does not have a policy with respect to combining or separating the Chairman and Chief Executive Officer positions. Under the current Board leadership structure, the positions of Chairman and Chief Executive Officer are combined into one role because our Board believes that as an employee-controlled company, CH2M is best served by a Board where an employee Board member serves as the chair of the Board. For this reason, and because Ms. Hinman is eminently qualified for the role, our Board believes that combining the roles of Chief Executive Officer and Chairman of the Board is appropriate at this time and is in the best interest of CH2M.

Under our Board's Governance Principles, the independent directors of our Board also designate one of the independent directors as Lead Director to provide independent leadership on the Board. The Lead Director initiates and presides at the meetings of independent directors, initiates meetings of all the Directors (including or excluding the Chairman and Chief Executive Officer), and presides at specific sessions of Board meetings as agreed with the Chairman and Chief Executive Officer. The Lead Director also facilitates communication between the independent directors and the Chairman and Chief Executive Officer, facilitates relationships among Board members and works with the Chairman and Chief Executive Officer in planning Board meeting schedules and agendas. In addition, the Lead Director serves as a sounding board to the Chairman and Chief Executive Officer on key issues facing CH2M, works with the Chair of the Compensation Committee on the performance and compensation of the Chairman and Chief Executive Officer and acts as a liaison to shareholders who wish to communicate with independent directors. Charles "Chad" Holliday, Jr. has served as the Lead Director since 2012. The independent directors may retain or change this appointment after the stockholders elect the nominees for Board membership at the annual meeting.

Board's Role in Risk Oversight

Our Board oversees CH2M's risk management process through its Audit and Risk Committees to ensure that enterprise and major project risks are considered and managed in a timely manner. In addition, our Board routinely reviews CH2M's strategy and capital planning. The Risk Committee of the Board oversees CH2M's enterprise risk management systems and processes, including the identification of major project and portfolio risks and other risks facing our industry generally and our company specifically. The Risk Committee reports to our Board on the enterprise risk management program and offers review and guidance to our management on our approach and process to assess and analyze project- and program-related risks. The Audit Committee reviews risk assessment and management policies, reviews financial and compliance risks and risk management and reviews major financial risk exposures and plans to manage them. The Audit and Risk Committees typically report to our Board on their respective activities at every Board meeting.

Communications with the Board

Stockholders may communicate with our Board by writing to them in care of Thomas M. McCoy, Executive Vice President, General Counsel and Corporate Secretary, CH2M HILL Companies, Ltd., 9191 South Jamaica Street,

12     CH2M 2016 Proxy Statement

Englewood, Colorado 80112 or to the Lead Director at 9191 South Jamaica Street, Englewood, CO 80112. All communications should indicate whether they are intended for the full Board, for outside independent directors only, or for any particular Board member. The inquiries will be directed to the appropriate Board member or members who will reply to stockholders directly.

Nominations of Directors

Our Governance and Corporate Citizenship Committee identifies and recommends for nomination individuals it believes are qualified to be employee and independent Board members and who are best suited to contribute to the Board's activities to serve CH2M's needs and objectives. The Board seeks directors with diverse professional backgrounds and reputations for integrity who combine a broad spectrum of experience and expertise that is important to CH2M's goals and strategy. Diversity of background has always been an important objective in the selection of directors. A candidate for director should have experience in positions with a high degree of responsibility and be selected based upon contributions they can make to the Board and upon their willingness to devote adequate time and effort to Board responsibilities. In making this assessment, the Governance and Corporate Citizenship Committee considers the candidates' knowledge of our industry and markets, and our clients' industries and markets, the number of other boards on which the candidate serves, strategic thinking and communication skills, and the other business and professional commitments of the candidate. The candidate should also have the ability to exercise sound independent business judgment to act in what he or she reasonably believes to be in the best interest of CH2M and our stockholders. Candidates for independent director positions must fulfill the Board's independence standards for independent directors as described above and included in the Governance Principles which are available on our website at http://ir.ch2m.com/corporate-governance.

In selecting employee directors for consideration, the Governance and Corporate Citizenship Committee takes into account the recommendation of the Chairman of the Board and Chief Executive Officer based on input received from our employee stockholders. The process for annual board nominations for employee director candidates commences with the Chairman of the Board and the Chief Executive Officer sending a detailed description of the nominating process and qualification requirements for Board membership to all employee stockholders. The solicitation process and the resulting nominations are reviewed by the Governance and Corporate Citizenship Committee, which makes its own recommendations to the full Board. The Governance and Corporate Citizenship Committee of the Board reviews the recommendations from the Chairman of the Board and the Chief Executive Officer and recommends to the Board a slate of candidates for employee director slots. The Governance and Corporate Citizenship Committee considers the Chairman and the Chief Executive Officer's recommendations in its deliberations, but is not bound by them.

The criteria for employee director nominees includes, among other things:

•

Personal characteristics of the highest caliber, including personal and professional ethics,

•

Proven leadership abilities, including demonstrated teamwork skills,

•

Experience and capabilities similar to those required of senior corporate officers, including at least fifteen years' experience in engineering- and construction-related businesses,

•

Diversity of gender, race, culture, background and experience to broaden the Board's perspective and to reflect the diversity of our clients and stakeholders,

•

Knowledge of CH2M's organization and culture, and

•

Differentiated skills relevant to the issues the Board anticipates addressing during the Board term.

Code of Ethics

We have adopted a code of ethics and business conduct for our executive and financial officers entitled "CH2M HILL Executive and Financial Officers' Code of Ethics." It applies to all of our senior executives and financial officers, including our Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer, Chief Human Resources Officer, General Counsel, Treasurer and Presidents of our business groups. The code is available on our website at

Executive Summary

In 2015, CH2M achieved solid year-over-year financial performance. Moreover, we made significant progress on a variety of operational measures and strategic initiatives. In particular, the Compensation Committee considered the following results in evaluating the Company's performance:

2015 Company Performance Highlights

•

Realized $5.36 billion in revenue and $80 million in net income.

•

Ended the year with a healthy balance sheet including $197 million in cash and cash equivalents.

•

•

•

Capped off a year of solid performance in 2015 by being honored by Ethisphere in March 2016 as one of the World's Most Ethical Companies, as has been the case every year since 2009.

The Compensation Committee approved adjustments to the 2016 compensation for our Named Executive Officers based on the Company's performance in 2015 and the competitive market analysis conducted by the independent compensation consultant (see the Key Elements of Compensation section below for more detail).

Compensation Philosophy

Our executive compensation programs are designed to attract and retain our senior executives, and motivate them to achieve CH2M's short- and long-term operational and financial goals in the best long-term interest of CH2M's stockholders. They are also designed to ensure that the compensation packages for our executives are aligned to

22     CH2M 2016 Proxy Statement

market practices and benchmarks. We also have a strong pay-for-performance philosophy. As a result, approximately 76% of the 2015 target compensation for our Named Executive Officers was linked to CH2M performance objectives, individual performance objectives, and stock price performance.

Our compensation philosophy is based on two fundamental principles: competitive market compensation and pay-for-performance:

•

Competitive Market Compensation.  CH2M pays its executives and other employees compensation that compares to compensation paid by industry peers because the market for qualified executives and employees in our industry is highly competitive. We also evaluate competitive pay practices among general industry companies of similar size, complexity and performance because certain executives may be drawn from this broader market. We target all elements of our compensation programs to provide compensation opportunity at the median of our peer companies and/or general industry. Actual payouts under these programs can be above or below the median based on CH2M's performance and each executive's individual performance.

•

Pay-for-Performance.  We align the interest of our executives and employees with the interest of our stockholders by paying for performance against agreed upon goals that tie with CH2M's short- and long-term objectives and strategic plans. We place a substantial portion of our executive officers' compensation at-risk, where total compensation over time depends on each executive's performance against established goals and on the overall performance of the company. Furthermore, a significant portion of all executives' compensation is provided in the form of CH2M stock, stock options, and restricted stock, which tie the total value of the compensation opportunity to CH2M's overall stock performance.

The long-term incentive awards granted to our executive officers are aligned to the strategic goals and long-term financial performance of CH2M, in line with our pay-for-performance philosophy. These long-term incentives also help retain executives over time and provide a means by which executives can meet our stock ownership guidelines.

One of our main objectives is to make sure that CH2M's compensation policies and practices for its employees and its executive officers optimize CH2M's performance without encouraging unreasonable risks or incentivizing behavior which may result in a material adverse effect on the company. The design of our executive compensation programs, which combines short- and long-term incentives, ties considerable compensation to company performance and aligns executive officers' interests with the interests of the company's stockholders.

We review our compensation philosophy and objectives annually in light of our performance against our goals and the performance of our peer companies. This process takes into account market risks and opportunities as well as the economic environment. We revise our compensation objectives, as appropriate, to focus on our strategic goals and objectives, and our requirements in recruiting and retaining leadership talent.

Pay for Performance

Based on the competitive market analysis performed by Sibson Consulting, the 2015 total target compensation for our Named Executive Officers ranged from 76% to 116% of the peer group median, and from 80% to 113% of the survey median, respectively, consistent with differences in experience, overall qualifications and performance.

CH2M 2016 Proxy Statement    23

The charts below illustrate how the total target compensation for our NEOs includes a substantial portion of variable (performance-based, and therefore "at risk") compensation. "Fixed" compensation refers to base salary and "variable" compensation refers to performance-based pay, which is the aggregate of stock (including both restricted stock and LTIP), AIP, and stock options. "Cash" compensation refers to base salary and AIP, and "equity" compensation refers to LTIP, stock options, and restricted stock.

In 2015, 60% of Ms. Hinman's target total compensation was equity-based and 82% was variable, and the average across all five NEOs was 54% equity-based and 76% variable.

The total target compensation changes for 2016 resulted in a slight increase in equity-based and variable compensation as illustrated below. Ms. Hinman's equity-based target compensation increased to 65%, and her variable target compensation increased to 84%. Similarly, the average across all NEOs increased to 58% equity-based and 79% variable. Mr. Madia is not included in the 2016 numbers due to his retirement.

Governance, Decision Makers, and Roles and Responsibilities

Stockholder Engagement and Say on Pay

We launched new stockholder communication initiatives in the last 18 months to provide more information and appealing access to CH2M's ownership program and company performance. These initiatives include:

•

Dedicated CH2M stockholder website providing easy access to our SEC filings and background information on the stockholder program. Stockholders can also submit questions via the website.

•

Reformatted CEO quarterly report with key financial results summarized in an easy-to-read format. The report is posted on our stockholder website and is now available to all stockholders.

•

Quarterly stockholder update calls hosted by Jacqueline C. Hinman, President, Chief Executive Officer and Chairman of the Board of Directors. These calls provide updates on company performance and the stock program, and recordings are posted on the stockholder website for those who aren't able to listen live.

CH2M provided stockholders a non-binding advisory "say-on-pay" vote on its executive compensation at its 2014 annual meeting of stockholders. Stockholders supported the compensation of our Named Executive Officers as disclosed in the proxy statement for the 2014 meeting, with the proposal receiving support of approximately 82% of the votes cast. Our next say-on-pay and say-on-pay frequency votes are scheduled for 2017.

Governance Practices

The below table summarizes the practices that CH2M incorporates into its compensation programs, as well as the practices we do not engage in.

Practices CH2M Does Use

✓ Pay for performance — 76% of 2015 target compensation for NEOs was performance-based. In addition, a significant portion of NEO target compensation is "at risk" as demonstrated by forfeiture of the 2012 restricted stock grants and no payments under the 2014 AIP or 2012 LTIP	✓ Compensation Committee oversight and approval of NEO compensation
✓ Independent compensation consultant	✓ Change of control payments/vesting have a double trigger
✓ Benchmarking based on market data for peer companies and general industry	✓ Capped incentive payouts — 200% for AIP and LTIP
✓ Regular stockholder communications and quarterly calls	✓ Executive stock ownership guidelines

Practices CH2M Does NOT Use

✗ No employment agreements	✗ No cash perquisite allowance, country club fees, or company planes
✗ No executive re-pricing of under-water options	✗ No defined benefit pension (frozen in late 1993/early 1994). Replaced by market-competitive defined contribution executive retirement plan for senior executives only
✗ No tax gross-ups on change of control payments	✗ No hedging

Roles and Responsibilities

Our compensation programs include effective Board oversight, strong governance practices and a focus on alignment with stockholder interests. To ensure our executives are rewarded appropriately for performance and not incented to take risks which exceed our risk tolerance, our compensation practices also reflect prudent risk management principles. The Compensation Committee regularly monitors our programs to ensure they remain aligned with compensation best practices, regulatory requirements and feedback from our stockholders.

Compensation Committee

Our Board of Directors delegates the responsibility for determination and oversight of executive officers' compensation to its Compensation Committee. The Committee determines total compensation for the Chief Executive Officer based on her performance, the company's performance, and input the Committee receives from its independent compensation consultant. Based on market data provided by the compensation consultant, the Committee also reviews the CEO's compensation recommendations for the other Named Executive Officers and other key executives and ultimately approves such compensation.

26     CH2M 2016 Proxy Statement

In addition, the Committee recommends, for Board consideration and approval, compensation for independent members of the Board of Directors, and also reviews and approves the equity-based and cash-based incentive compensation plans designed to drive the company's strategic, operational, and financial objectives.

Independent Compensation Consultant

The Compensation Committee retains an independent compensation consultant to assist it in performing its responsibilities. In 2015, the Compensation Committee retained the services of Sibson Consulting ("Sibson"). At the request of the Committee, Sibson updates the annual compensation assessment for the CEO and other executive officers. This review provides a comprehensive assessment of the various components of our executive compensation programs against relevant market compensation data and practices from our peer companies and the general industry, as well as a recommended compensation range for our CEO and reference compensation ranges for our other executive officers. The Compensation Committee uses this information to consider and set compensation for the CEO and to review the CEO's recommendations for other executive officers' compensation. As part of this process, Sibson also provides compensation data for other key executives and managers at peer companies, which are used by the company in considering compensation levels. In addition, Sibson conducts an annual review of our peer companies to ensure they are appropriate for our annual compensation assessment, and also performs a sensitivity analysis of our incentive plans to ensure that the risk-reward relationship between performance and awards is aligned to the company's strategy and does not represent undue risk for the business. We paid Sibson approximately $269,251 for work performed in 2015.

In 2015, the Compensation Committee carefully considered Sibson's independence and all the services that Sibson provides to CH2M's management, and determined that Sibson's services to the company did not impair its independence because the value of compensation that Sibson derives from such services was not significant to its business.

CEO/Executive Management

CH2M's Chief Executive Officer reviews compensation data and analysis for all executive officers, including the information provided by Sibson Consulting. The CEO considers each component of executive compensation and determines how these components should be used to provide appropriate total compensation that motivates executive officers to optimize CH2M's short- and long-term operations and financial results in the best interest of CH2M's stockholders. The CEO then provides an overview of performance and accomplishments for each executive officer and makes recommendations to the Compensation Committee about the compensation levels and structure that the CEO deems appropriate. The CEO's recommendations are influential but not dispositive in the determinations of the Committee.

Benchmarking and Peer Companies

The Compensation Committee uses market data as a primary tool in establishing compensation for the Chief Executive Officer and the Board of Directors, and in reviewing the CEO's recommendations for compensation of other executive officers and then making its determinations.

In establishing 2015 compensation, the Compensation Committee reviewed total compensation information from general industry survey data, as well as proxy data for thirteen peer companies based on analysis prepared by Sibson Consulting. In considering which peer companies to include for this review, the Committee instructed Sibson to include companies of similar size and complexity that compete with CH2M for executive talent in our industry and our

CH2M 2016 Proxy Statement    27

geographic markets. The Committee believes that the reference group of peer companies set forth below was appropriate for its compensation analysis.^* There were no year-over-year changes to the peer group.

Peer Company	2014 Revenue (in millions)		2014 Rank
Fluor	$	21,532		1
Chicago Bridge & Iron	$	12,975		2
Jacobs Engineering	$	12,695		3

Willbros Group, Inc.	$	2,027		11
Foster Wheeler*		N/A		N/A
URS*		N/A		N/A
CH2M	$	5,413

*

In 2015, URS was removed from the peer group due to its merger with AECOM, and Foster Wheeler was re-named AMEC Foster Wheeler due to its acquisition by AMEC. These changes were reflected in the November 2015 compensation analysis used to set 2016 compensation. In addition, URS and Foster Wheeler did not report 2014 revenue because of their mergers.

Key Elements of Compensation

The Compensation Committee believes that, by creating a total compensation package for our executive officers that combines short- and long-term incentives, we align their interests with the interests of CH2M and its stockholders. We review our performance against our peer companies as a factor in determining our executive officers' total compensation. We also believe our pay-for-performance model appropriately motivates performance and encourages appropriate risk taking, while encouraging retention. As our financial performance increases relative to our performance goals, the executive officers' potential for additional compensation under our short- and long-term incentive programs increases as well. If our performance does not meet our goals, total compensation falls and incentive compensation may be reduced to zero.

The key elements of the total compensation awarded to our Named Executive Officers include: base salary, a cash-based annual incentive award, and equity-based long-term incentives consisting of common stock, stock options, and restricted stock as summarized in the below table. We also offer market-competitive benefits and select perquisites.

Base Salary

We provide our NEOs with an annual base salary that we believe is appropriate for their responsibilities, experience, and the complexity and strategic impact of their roles. Each role has a market-competitive range based on peer and survey data as determined by the Compensation Committee with input from its independent compensation consultant. The position of the executive within the range for their role is based on their experience, qualifications, and performance.

The Compensation Committee reviewed the salaries for the NEOs and the competitive market data at the November 2014 Compensation Committee meeting, and determined that no adjustments would be made for 2015 in light of the company's performance in 2014, with the exception of Mr. McIntyre due to his promotion in January 2015 to President, Global Business Groups. The Committee conducted a similar review at the December 2015 Board meeting and made adjustments based on the market position of each executive and the company's positive performance in 2015. Annual salaries for 2014, 2015, and 2016 are summarized in the below table.

NEO	2014 Annual Salary			2015 Annual Salary			2014-15 % Change			2016 Annual Salary			2015-16 % Change
Hinman		$	900,000		$	900,000		0	%		$	1,000,000		11.1	%

McCoy		$	500,000		$	500,000		0	%		$	520,000		4.0	%

Annual Incentive Plan

The Annual Incentive Plan (AIP) is our performance-based, short-term incentive program, and comprises a portion of each NEO's variable ("at risk") compensation. Three levels of performance are factored into each AIP: enterprise, business unit, and individual. A new plan is established each year and the Compensation Committee approves the plan's performance goals as well as the target incentive for each NEO. The performance period is from January 1 through December 31, and final determination of awards is made at the Compensation Committee meeting in February following the end of the performance period. Awards are typically paid in 100 percent cash in keeping with market practice of our reference group of peer companies.

In order to ensure a focus on both profitability and future business growth, the two primary goals for the 2015 plan were enterprise and business unit earnings and New Gross Margin In (NGMI). For plan participants at the business-unit level, the enterprise goals are weighted at 40% and the business unit goals are weighted at 60%. For participants at the enterprise level, including all NEOs, the enterprise goals are weighted at 100%. After business unit and enterprise performance results are used to adjust target awards up or down, each participant's individual modifier is applied to calculate the final award payout. The individual modifier reflects, amongst other factors, individual performance relative to annual goals and individual contribution to the attainment of enterprise and business unit strategic objectives.

Both the enterprise and business unit objectives must meet a 70% threshold in order for the respective targets to pay out, and the maximum payout is 200% for each factor.

30     CH2M 2016 Proxy Statement

In February 2016 the Compensation Committee approved the final awards for the NEOs as follows:

NEO	2015 AIP Target %			2015 AIP Target $		Final Award Paid March 2016
Hinman		120	%	$	1,080,000		$	1,273,050

McIntyre		75	%	$	337,500		$	366,002
McCoy		75	%	$	375,000		$	353,625

The 2016 AIP performance goals, as well as the NEO targets, were approved at the December 2015 Compensation Committee meeting. The performance goals are enterprise earnings and New Gross Margin In (NGMI), with a 70% minimum threshold and a 200% maximum payout. In 2016, all plan participants will be measured on enterprise performance in order to foster increased collaboration and teamwork across the enterprise. The 2016 NEO target awards are summarized as follows:

NEO	2016 Base Salary			2016 AIP Target %			2016 AIP Target $
Hinman		$	1,000,000		120	%	$	1,200,000
McArthur		$	600,000		90	%	$	540,000
Madia		N/A			N/A		N/A
McIntyre		$	480,000		80	%	$	384,000
McCoy		$	520,000		80	%	$	416,000

Long-Term Incentive Compensation

The long-term component of our incentive compensation is intended to reward and retain our executives, motivate them to focus on long-term goals and increase stockholder value, and help them meet their Executive Stock Ownership Guidelines. Long-term incentive (LTI) compensation includes the Long-Term Incentive Plan (LTIP) and annual stock option and restricted stock grants, and the mix between the two components varies depending on the job level of each executive.

In November 2014, the Compensation Committee approved the 2015 long-term incentive targets for the NEOs. Based on the company's 2014 performance, the 2015 targets were the same as the 2014 targets, with the exception of Mr. McIntyre due to his promotion in January 2015 to President, Global Business Groups. Similarly, at the December 2015 Compensation Committee meeting, the 2016 long-term incentive targets were reviewed. The adjustments summarized below were approved based on the market position of each executive.

CH2M 2016 Proxy Statement    31

The 2014, 2015 and 2016 total long-term incentive target awards are summarized in the table below. The total LTI targets comprise both the Long-Term Incentive Plan target as well as the target for the stock option and restricted stock grants, both of which are discussed more fully in the sections below.

Long-Term Incentive Plan (LTIP)

The Long-Term Incentive Plan (LTIP) is our performance-based, long-term incentive program, and comprises a portion of each NEO's variable ("at risk") compensation. Each LTIP has a three-year performance period, and a new plan is established each year. Therefore, there are three plans outstanding at any one time.

The Compensation Committee approves the performance goals for each new plan as well as the target incentive for each NEO. Whereas the Annual Incentive Plan typically has enterprise, business unit, and individual performance criteria, the LTIP utilizes enterprise performance goals only. Although the specific goals for the outstanding plans vary slightly, each LTIP has an earnings goal and gross margin goal in order to ensure a focus on both profitability and future revenue growth. Final determination of awards is made at the Compensation Committee meeting in February following the end of the three-year performance period. Awards are typically paid 100 percent in CH2M stock.

At the February 2016 Compensation Committee meeting, the payout percentage for the 2013 LTIP (for the 2013-2015 program period) was approved at 57.2% for all participants other than the current NEOs. The 2013 LTIP was set with two performance metrics which were Earnings Before Bonus and Tax (EBBT) weighted at 80% and Gross Margin Backlog Compounded Annual Growth Rate (CAGR) weighted at 20%. The EBBT metric was met with a result of 41.2% but the Gross Margin Backlog CAGR was below the minimum threshold and therefore the result was 0%. The two performance metrics combined must meet a 50% minimum result for payment under the plan, unless otherwise determined by the Compensation Committee under the LTIP. When the metrics were set in 2012, our strategy emphasized continuation of (and substantial growth in) our EPC and Design-Build (D/B) business. Such types of projects generally have larger gross margin associated with them than our traditional consulting projects. However, starting in September 2013, and continuing into 2014, we reset our strategy around EPC and D/B services. With removing the discontinued EPC and D/B business (with the exception of Water D/B which has not been discontinued) from the planned 2013 Gross Margin Backlog (starting) number, the result would be at target or 20%. The Compensation Committee took this into consideration but also believes expectations on the consulting business would have been set at a higher level. Based on these factors, the Compensation Committee arrived at the 57.2% payout percentage (excluding the current NEOs).

At the December 2015 meeting the Committee approved the NEO target awards for the 2016 plan.

The goals and performance periods for the 2013 - 2016 LTIPs are summarized as follows:

Messrs. McArthur and McCoy were not participants in the 2013 LTIP.

Although the performance metrics for the 2013 LTIP were not met, in February 2016 the Compensation Committee approved an award payout under the 2013 LTIP for all participants other than NEOs at the time, including Ms. Hinman and Mr. McIntyre, who were the only 2015 NEOs excluded from the 2013 LTIP award. Mr. Madia was not considered an NEO by the Compensation Committee at the time of its decision due to his retirement as an executive officer in January 2016, and Mr. Madia was consequently awarded a payout under the 2013 LTIP. Based on the individual contributions of Ms. Hinman and Mr. McIntyre to the firm's achievement of year-over-year growth from 2014 to 2015, the Committee believed it appropriate to recognize their contributions, outside of the LTIP, with a discretionary award of CH2M stock valued at $220,000 and $125,000, respectively.

Finally, the target awards for the 2014-2016 plans are summarized as follows:

NEO	2014 Base Salary			2014 LTIP Target %			2014 LTIP Target $		2015 Base Salary			2015 LTIP Target %			2015 LTIP Target $		2016 Base Salary		2016 LTIP Target %			2016 LTIP Target $

CH2M 2016 Proxy Statement    33

Due to his retirement as Executive Vice President and Chief Human Resources Officer, Mr. Madia's payments under the 2014 and 2015 plans will be prorated based on the number of full months worked during each plan's 36-month performance period as outlined in the plan document. The prorated payments will be subject to the minimum performance thresholds established under each plan and will be paid in March 2017 and 2018, respectively.

Consistent with our pay-for-performance philosophy, the LTIP provides the Compensation Committee with discretion to reduce actual payouts to ensure that any one operational performance goal is not achieved at the expense of other important strategic objectives.

Annual Stock Option and Restricted Stock Grants

Our executive officers receive annual stock option and restricted stock grants that comprise the third major portion of their variable ("at risk") compensation. The total grant amount is calculated as a percentage of base salary, which is then divided into 75% stock options and 25% restricted stock. The Compensation Committee approves the equity target for each NEO.

Stock options are granted to our executives to provide an attractive incentive to focus on our longer term strategic goals and create stockholder value. Our grants are made with the strike price equal to the stock price in effect on the grant date. They vest 25% on the first anniversary of the grant date, 25% on the second anniversary, and 50% on the third anniversary, and expire after five years. Although we are required to reflect compensation expense for stock options pursuant to applicable accounting rules, the granted stock options only have realized value to the executive to the extent that our stock price increases during the term of the stock options.

Restricted stock is granted to our executives to motivate and reward them for the achievement of specified financial goals. Each annual grant has a three-year cliff vesting schedule, and a performance feature that can increase or decrease the number of shares that ultimately vest after the restricted period has ended. Although the performance targets for the outstanding grants vary slightly, each restricted stock grant has an EBITDA (earnings before interest, taxes, depreciation and amortization) goal to ensure a focus on profitability. Final determination of awards is made at the Compensation Committee meeting in February following the end of the three-year performance period.

The grant date value of the equity awards (including both restricted stock and stock options) granted in 2014, 2015, and 2016 is summarized as follows:

Other Compensation Programs

In November 2014, the Compensation Committee approved a compensation program (called the CEO Fund) to retain the people critical to advancing strategic imperatives and CH2M's turnaround in 2015. In light of the absence of payments under the Annual Incentive Plan in 2014 and lower than target AIP payments in prior years, the Committee determined that the CEO Fund was essential to retaining key employees during a time of highly competitive recruiting in the industry. Accordingly, the Committee approved the use of up to $5 million for CEO Fund incentives in 2015. In May 2015, the Committee approved awards valued at $2.8 million for employees at various levels and roles in the organization based on their respective contributions toward advancing strategic imperatives and driving company results, as follows:

•

a 2.5% salary increase during the second half of 2015 for certain members of middle management, which individuals had not received a salary increase in 2014; and

•

retention awards for approximately sixty senior leaders that had strategic roles in achieving CH2M's turnaround.

The awards to each of the NEOs are included in the Summary Compensation Table at the end of this narrative. A one-year payback clause was included in each recipient's agreement for retention purposes. All incentive awards under the CEO Fund granted to executive members of management were approved by the Compensation Committee, and the incentive award to the CEO was determined independently and solely by the Compensation Committee. For other recipients of the incentive awards, a committee composed of executive members of management approved the selection of such other recipients and the amount of their awards. NEO awards under this program are as follows:

NEO	CEO Fund Award
Hinman	$	300,000
McArthur	$	250,000
Madia	$	100,000
McIntyre	$	200,000
McCoy	$	100,000

In February 2016, the Compensation Committee approved discretionary stock awards to Ms. Hinman and Mr. McIntyre in lieu of awards under the 2013 LTIP since the performance metrics set in 2013 for the 2013 LTIP (for the 2013 - 2015 program period) were not met. Whereas the Compensation Committee nevertheless approved an award payout under the 2013 LTIP for all participants other than current NEOs, Ms. Hinman and Mr. McIntyre as the only current NEOs who are participants in the 2013 LTIP were excluded from the 2013 LTIP award that is payable 100% in CH2M stock. Based

36     CH2M 2016 Proxy Statement

on their individual contributions to the firm's achievement of year-over-year growth from 2014 to 2015, the Committee believed it appropriate to recognize their contributions, outside of the LTIP, with a discretionary award of CH2M stock. In making this determination, the Committee considered the growth in the New Gross Margin In during the 2015 performance year which has positioned the company to meet or exceed its targets for continued growth in 2016. No other current NEOs were approved for a discretionary stock award at the February 2016 Compensation Committee meeting. These discretionary awards are included in the Summary Compensation Table at the end of this narrative.

2015 and 2016 NEO Compensation

We look at executive compensation in multiple ways, including (1) target total compensation, (2) actual compensation realized, and (3) total compensation using the methodology required by the Securities and Exchange Commission (SEC) for the Summary Compensation Table (SCT).

The below chart highlights the primary differences between these 3 methods:

2015 Target Total Compensation	Actual Compensation Realized in 2015	2015 Total Compensation in Summary Compensation Table*
2015 Base Salary	Base Salary Earned in 2015	Base Salary Earned in 2015
Target 2015 Annual Incentive (Paid in 2016)	Actual Annual Incentive for 2015 Performance (Paid in 2016)	Actual Annual Incentive for 2015 Performance (Paid in 2016)
Target 2015 Long-Term Incentive (Paid in 2018)	Actual Long-Term Incentive for 2013-2015 Performance (Paid in 2016)	Actual Long-Term Incentive for 2013-2015 Performance (Paid in 2016)

For comparison purposes, this shows only a portion of the compensation included in the Summary Compensation Table. For complete details please refer to the table at the end of this narrative.

The data we report in the Summary Compensation Table (SCT) at the end of this narrative is based on the requirements of the Securities and Exchange Commission (SEC). Because all companies are required to present data in the same way in the SCT, the consistent format makes it easy to make comparisons between different companies. However, we believe that it is also important to look at target total compensation as well as actual compensation realized. Target total compensation includes a significant portion of performance-based compensation that may become actual compensation realized in future years based on company performance.

NEO Target Total Compensation

2015 Target Total Compensation

Target total compensation for the Named Executive Officers in 2015 is summarized below. As discussed above, since our incentive plans have performance criteria and performance periods with varying time horizons, the actual compensation earned can be higher or lower than target compensation in a given year.

Grant date value of annual restricted stock and stock option awards.

Based on the competitive market analysis performed by Sibson Consulting, the 2015 total target compensation for our Named Executive Officers ranged from 76% to 116% of peer group median, and from 80% to 113% of the survey median, respectively, consistent with differences in experience, overall qualifications, and performance. Ms. Hinman's 2015 total target compensation was 78% of the peer group median and 80% of the general industry survey median.

2016 Target Total Compensation

Based on the company's 2015 performance and the data from Sibson's competitive market analysis, the Compensation Committee approved the 2016 total target direct compensation for the NEOs as summarized below. These changes improved the competitive market position of our NEOs in keeping with our compensation philosophy.

Grant date value of annual restricted stock and stock option awards.

As a result of the adjustments, 2016 total target compensation ranged from 85% to 112% of the peer group median, and 96% to 112% of the survey median, respectively, consistent with differences in experience, overall qualifications, and performance. Ms. Hinman's 2016 total target compensation is 91% of the peer group median and 107% of the general industry survey median. The 2016 market position of the NEOs is based on the more recent competitive market assessment conducted by Sibson Consulting in November 2015 using more recent market data with a slightly different peer group as discussed above in the Benchmarking and Peer Companies section (removal of URS due to its merger with AECOM, and re-naming of Foster Wheeler to AMEC Foster Wheeler due the acquisition of Foster Wheeler by AMEC). Due to his retirement, Mr. Madia is not included in these numbers.

NEO Actual Compensation Realized

In addition to total target compensation, we also look at actual pay realized so that we can more clearly show the relationship between company performance and actual NEO compensation. Actual performance for variable compensation programs can result in actual compensation that is significantly higher or lower than total target compensation.

The table below shows the primary components of the actual pay realized in 2015 for each NEO, including 2015 base salary, short- and long-term incentives earned in 2015, the value of restricted stock that vested in 2015, and the gain on stock options exercised in 2015.

McCoy	$	500,011	$	353,625		N/A	$	100,000	N/A		N/A	$	0	$	953,636

*

These awards are treated as 2015 compensation because they were earned in 2015 even though they weren't paid until early 2016 after the end of the performance period.

**

As described above, the annual executive restricted stock grants have a three-year vesting period and also have an EBITDA-based performance feature. The performance result for the annual grants issued in 2012, which were scheduled to vest in 2015, was below the minimum threshold and therefore the shares did not vest. Messrs. McArthur and McCoy did not receive 2012 restricted stock grants because they were issued prior to their dates of hire. Mr. McIntyre received a separate, non-performance-based restricted stock grant in 2012 in lieu of participation in our Supplemental Executive Retirement and Retention Plan which did vest in 2015. Mr. McArthur received a separate 2014 restricted stock grant associated with our first-time buyer program which vested in 2015.

For all of the NEOs, actual compensation realized in 2015 was less than 2015 total target compensation. This is primarily due to the performance goals and vesting schedules associated with the variable compensation programs, as well as the 2012 performance-based restricted stock grants not vesting because the minimum threshold was not met.

Retirement Programs, Perquisites, and Other Benefits

Our executive officers are eligible to participate in benefit plans that are available to substantially all of our employees, including participation in our medical, dental, disability, and life insurance plans. In addition to these general benefits, we offer financial planning consulting and executive physicals. In keeping with our philosophy of market-competitive and pay-for-performance compensation, we have historically provided only modest executive benefits and perquisites, and have not viewed these forms of compensation as a substantial part of the overall executive officers' compensation framework.

Limited Perquisites

We do not believe that providing generous executive perquisites is either necessary to attract and retain executive talent or consistent with our pay-for-performance philosophy. Accordingly, we provide only limited and modest perquisites to our executive officers, principally financial planning services and an executive physical examination. We provide these benefits to help our executives maintain their health and manage their finances, in both cases so that they are able to focus their attention on CH2M. We do not provide perquisites such as excise tax gross-ups (except on the financial planning perquisite), company automobiles, security services, club memberships, apartments or vacation homes to our executive officers.

One special benefit that we provide to a select group of executives is our Supplemental Executive Retirement and Retention Plan (SERRP). The SERRP is a non-qualified defined contribution plan under which CH2M provides pre-tax contributions that are distributed only after retirement from the company at age 65 or thereafter. The plan provides

CH2M 2016 Proxy Statement    39

those who are invited to participate in the plan with added incentives to continue in the service of the company by providing an attractive retirement benefit. The SERRP is a part of our competitive market compensation strategy and it allows us to attract and retain our senior executives.

The company contribution to each Named Executive Officer's SERRP account is the following percentage of base salary and short-term incentive: 25% for Ms. Hinman and Mr. Madia, 12.5% for Mr. McArthur and Mr. McIntyre, and 15.7% for Mr. McCoy.

During the life of the SERRP, the contribution levels may be set differently for different participants, and at different percentages of base salary and short-term incentive, as determined by the Compensation Committee. Ms. Hinman and Mr. Madia were participants in the original SERRP implemented in 2009, which was a non-qualified, hybrid defined-benefit/defined-contribution plan with a goal of providing 50% of the participants' final compensation in retirement. The plan was restated in 2012 and became a non-qualified, defined contribution plan with individual contribution percentages defined by the participant's age and job level. The original contribution percentages for Ms. Hinman and Mr. Madia were grandfathered under the old plan.

SERRP contributions have the following vesting schedules:

•

Annual contributions under the original plan vest 20% at the end of each plan year for five years.

•

Annual contributions under the restated plan have two vesting schedules depending on the contribution type: "reward" contributions vest 20% at the end of each plan year for five years, and "retention" contributions become 100% vested at age 65.

We also have a Deferred Compensation Plan (DCP) that allows CH2M the opportunity to provide a company match for compensation deferrals made by highly compensated employees whose 401(k) Plan contributions are limited by the Employee Retirement Income Security Act. All of the NEOs are participants in the DCP and they all received company contributions in 2015. Because the executive officers deferred the minimum required portion of their own 2015 base salary, CH2M contributed 6% of 2015 base pay in excess of the IRS limitation on compensation for qualified plans.

Participants are 100% vested at all times on DCP employee deferrals and earnings on those deferrals. Company contributions to the plan made prior to January 1, 2011, and the earnings thereon, become 100% vested after the earlier of: (a) completion of six years of vesting service (contributions vest 20% per year in years two through six), (b) attainment of age 65, or (c) attainment of age 55 and completion of five years of vesting service. Company contributions made after January 1, 2011 cliff vest when the employee qualifies for retirement under the plan (age 55) or as otherwise determined by the Compensation Committee.

Finally, CH2M provides for a payment of five times base salary (pre-tax) in a lump sum to the beneficiary of select CH2M executives, including the Named Executive Officers, upon their death. This is a pre-retirement employment benefit similar to term life insurance while the executive remains a CH2M employee.

Other Programs, Policies, and Guidelines

Executive Stock Ownership Guidelines

CH2M's Board of Directors has established stock ownership guidelines for our senior executives. The guidelines are intended to encourage management to own a meaningful amount of CH2M stock and therefore align individual financial goals with our company's success. Executives will achieve their recommended levels of ownership within five years of being promoted into a role or assuming a new position which is subject to the guidelines. The Compensation Committee reviews each executive's progress toward compliance with the guidelines. The Committee also reviews the executive stock ownership guidelines from time to time.

40     CH2M 2016 Proxy Statement

The following table sets forth the current stock ownership guidelines as approved by the Compensation Committee:

Position	Minimum Stock Ownership (as a multiple of Annual Base Salary)
Chief Executive Officer	Five Times Salary
Other Named Executive Officers	Three Times Salary
Other Senior Executives	Two Times Salary

Change of Control Compensation

Each of our Named Executive Officers has a change of control agreement with the company. Under these agreements, CH2M will provide the following benefits in the event of a covered termination of employment (the termination of the executive's employment by CH2M other than for cause or by the executive for good reason) that occurs within twenty-four months of a change of control:

•

Lump-sum cash payment in the amount equal to the sum of (a) 2.99 times the executive's highest annual base salary in effect during the twelve (12) month period immediately preceding the termination date and (b) 2.99 times the executive's target annual bonus assuming achievement of performance goals at target at the rate in effect immediately prior to the termination date, payable in a cash lump sum;

•

Payout of the executive's annual bonus for the fiscal year immediately preceding the termination Date (but only to the extent not yet paid prior to the termination date), as determined by the Board on or before the termination date or if no determination has been made, the executive's target annual bonus assuming achievement of performance goals at target at the rate in effect immediately prior to the termination date;

•

As applicable, pro-rata payout of the executive's bonus payouts under the long term incentive plan for the open bonus periods that include the termination date year and the executive's bonus payouts under the long term incentive plan for the period that ends in the fiscal year immediately preceding the termination date (but only to the extent such bonus payouts have not been paid);

•

Immediate vesting in all retirement and deferred compensation plans;

•

Continuation of health benefits for a period equal to the period the executive would be entitled to continuation coverage under a group health plan of CH2M following the date of termination;

•

Continuation of the same level of accident, disability, life insurance and any other similar welfare benefits through the end of the last day of the second taxable year following the date of termination; and

•

Immediate vesting of all equity awards, including stock options, stock appreciation rights, restricted stock, phantom stock, and stock value equivalent units.

For purposes of the change of control agreements, a "change of control" is defined generally to include:

•

Acquisition that constitutes more than 50% of the total fair value of CH2M stock;

•

Acquisition of ownership of CH2M stock that represents 30% or more of the total voting power of Company stock;

•

A change in the majority of the Board of Directors, not otherwise recommended by the Board of Directors, during any 12-month period;

•

Liquidation or dissolution of CH2M, or acquisition of ownership of all or substantially all of the assets of CH2M.

Tax Deductibility and 162(m)

The Compensation Committee reviews executive compensation in light of Section 162(m) of the Internal Revenue Code which establishes a limit on the deductibility of annual compensation that exceeds $1,000,000 for certain executive officers. It is the general intention of the Committee to meet the requirements for deductibility under Section 162(m) of the Internal Revenue Code; however, the Committee reserves the right, where merited by changing business conditions or an executive's individual performance, to authorize compensation payments which may not be fully deductible by CH2M. The Committee reviews this policy on an ongoing basis.

CH2M 2016 Proxy Statement    41

Risks Inherent in Compensation Structure

CH2M's executive management and the Compensation Committee considered the company's compensation policies and practices for its executive officers and employees, in general, and determined that these policies and practices are reasonable and not likely to have a material adverse effect on the company. The design of the executive compensation program that combines short-term and long-term incentives places considerable compensation at-risk, and aligns executive officers' interests with the interests of the company's stockholders, thus creating an environment that encourages executive officers and other key employees to balance carefully risks and rewards for the company and not to assume unreasonable risks.

CH2M's executive management and the Compensation Committee carefully reviewed all elements of executive compensation to determine whether any components of compensation encourage excessive risk taking and concluded that:

•

Rolling three-year performance targets for long-term incentive compensation discourage short-term risk taking and encourage a long-term view,

•

The substantial equity component of compensation and ownership guidelines discourages excessive risk taking, and

•

The significant portion of at-risk compensation focused on long-term strategic results creates an appropriately measured approach to risk taking.

Further, as described elsewhere in the Compensation Discussion and Analysis, compensation decisions by the Compensation Committee include subjective considerations, which prevent a formulaic approach to compensation setting and do not drive unreasonable short-term focused business and risk taking decisions.

42     CH2M 2016 Proxy Statement

Compensation Committee Report

We evaluate and establish compensation for CH2M's executive officers and oversee the deferred compensation and equity-based compensation plans, and other management incentive, benefit and perquisite programs. Management has the primary responsibility for CH2M's financial statements and reporting process, including the disclosure of executive compensation. With this in mind, we have reviewed and discussed with management the Compensation Discussion and Analysis section of this proxy statement. We are satisfied that the Compensation Discussion and Analysis fairly and completely represents the philosophy, intent, and actions of the Compensation Committee with regard to executive compensation. We recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement for filing with the U.S. Securities and Exchange Commission.

Bonus amounts in column (d) for fiscal years 2015 consist of bonuses earned under the short term incentive plan and discretionary bonuses as described below.

The following table provides a summary of the bonuses earned during the years ended December 25, 2015, December 31, 2014, and December 31, 2013. The 2014 short-term incentive plan did not pay out because the minimum performance threshold was not met. Discretionary bonuses were paid in 2015 through a compensation program (called the CEO Fund) approved by the Compensation Committee. The purpose of this program was to reward and retain key employees for advancing strategic imperatives and driving company results.

Effective January 1, 2009, CH2M amended and restated the Deferred Compensation Retirement Plan (DCRP) to form the SERRP. The SERRP is intended to be unfunded and maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees within the meaning of Title I of the Employee Retirement Income Security Act. Under this plan, each participant's account consists of various contributions made to the account by CH2M on behalf of the participant. None of the NEOs were participants in the DCRP.

3

Aggregate earnings are not included in the Summary Compensation table because the earnings are not above market or preferential in nature. Earnings include the gain on CH2M stock as well as the gain or loss on cash-based investments. Only Ms. Hinman and Messrs. Madia and McIntyre have CH2M stock in their accounts.

Vested balances are as follows: Ms. Hinman — $1,991,559; Mr. McArthur — $151,190; Mr. Madia — $2,397,706; Mr. McIntyre — $4,135,979; and Mr. McCoy — $129,373. These amounts include both employee and employer contributions.

Director Compensation

Our non-employee director compensation is reviewed by an independent compensation consultant annually for competitiveness and appropriateness to peer and industry practices. In 2015, non-employee directors' compensation included an annual retainer of $80,000, which amount has been increased to $85,000 beginning in 2016. The lead director was paid an additional annual retainer of $17,500. In addition, the chair of the Audit Committee was paid an additional annual retainer of $15,000, and the chairs of the Compensation, Governance, and Risk Committees were each paid an additional annual retainer of $10,000, each of which amounts has been increased by $2,500 in 2016. The non-employee directors appointed by Apollo Global Management LLC do not receive any compensation.

Non-employee directors who are members of a Board committee received an additional annual fee of $5,000 for each Committee on which they served. Further, each non-employee director received a restricted stock award equal to $84,000 which cliff vests on the first anniversary of the date of grant. The value of the 2015 restricted stock grants reflected a 20% voluntary reduction of the previously approved value of $105,000 due to the company's performance in 2014, and the value of the 2016 restricted stock grants will be increased to $115,000, reflecting CH2M's improved performance. We may, at our discretion, award cash and stock bonuses to non-employee directors from time to time, although none were awarded in 2015.

Our employee directors do not receive additional compensation for their Board service. All of our directors are reimbursed for expenses incurred in connection with attendance at Board and committee meetings and for their service on our Board. The following table details the non-employee director compensation for the year ended December 25, 2015 and includes any individual who served as a non-employee director during 2015.

Restricted stock awards were granted on May 15, 2015, with a vest date of May 15, 2016. Compensation amounts were calculated in accordance with U.S. GAAP for awards issued pursuant to the CH2M Companies, Ltd. Amended and Restated Restricted Stock Plan. Under these rules, the grant date fair value of each award equals the number of shares granted multiplied by the stock price at the time of the grant. As of December 25, 2015, each non-employee director listed above held 1,643 shares of our common stock subject to restrictions.

On June 24, 2015, Mr. Geist entered into a letter agreement with CH2M in connection with his resignation from the Board of Directors and assumption of the title of director emeritus. The letter agreement sets forth the terms of Mr. Geist's service as director emeritus, including compensation for such service. For additional information, see "Certain Relationships and Related Transactions — Letter Agreement with Jerry D. Geist."

Our Board believes that its members should be long term stockholders of CH2M and has adopted a policy requiring each non-employee director within five years of election and for the duration of his or her tenure to hold CH2M equity in an amount equal to at least four times the annual retainer.

In this context, the Audit Committee has reviewed and discussed with management CH2M's financial reporting process, including the system of internal controls.

The Audit Committee has reviewed and discussed with management and the independent auditors the audited financial statements for the fiscal year ended December 25, 2015. The Audit Committee also has reviewed and discussed with management and the independent auditors the review of the Committee's financial reporting and internal controls undertaken in connection with certifications by CH2M's Chief Executive Officer and Chief Financial Officer pursuant to the Sarbanes-Oxley Act of 2002 in certain of the company's filings with the U.S. Securities and Exchange Commission. The Audit Committee also reviewed and discussed other matters as deemed appropriate, including the company's compliance with Section 404 of the Sarbanes-Oxley Act of 2002 and the other provisions of the Sarbanes-Oxley Act of 2002 and rules adopted or proposed to be adopted by the U.S. Securities and Exchange Commission. Additionally, the Audit Committee discussed with KPMG the matters required to be discussed by Auditing Standard No. 16, Communications with Audit Committees, as adopted by the Public Company Accounting Oversight Board (PCAOB).

The Audit Committee has received and reviewed the written disclosures and the letter from the independent auditors required by applicable requirements of the PCAOB regarding the independent auditors' communications with the Audit Committee concerning independence, and discussed with the independent auditors their independence from CH2M and its management. The Audit Committee also considered whether the independent auditors' provision of other non-audit services to CH2M is compatible with its independence.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements referred to above be included in CH2M's Annual Report on Form 10-K for the fiscal year ended December 25, 2015, for filing with the U.S. Securities and Exchange Commission.

Proposal 2. Ratification of the Appointment of the Independent Auditors

Additional Information

Advance Notice Procedures

Under CH2M's Bylaws, no business (including nominations for director) may be brought before an annual meeting by a stockholder unless written notice is delivered to CH2M's Secretary (containing certain information specified in the Bylaws about the stockholder and the proposed action) not less than 90 nor more than 120 days prior to the first anniversary of the preceding year's annual meeting — that is, with respect to the 2017 annual meeting, between January 10, 2017, and February 9, 2017. However, if the 2017 annual meeting is to be held on a date that is more than 30 days before or more than 70 days after May 10, 2017 (the first anniversary of the 2016 annual meeting), then such notice must be received not earlier than the 120th day and not later than the later of the 90th day prior to the date of the 2017 annual meeting or the 10th day following the day on which public announcement of the date of the 2017 annual meeting is first made by CH2M.

If a stockholder wishing to bring such a proposal does not provide notice of the proposal to the Corporate Secretary within the time period specified in our Bylaws, the chairman of the meeting shall have the power to declare that the proposed business will not be transacted at the annual meeting. These requirements are separate from the Securities and Exchange Commission's requirements that a stockholder must meet in order to have a stockholder proposal included in our Proxy Statement. Any notices should be sent to Thomas M. McCoy, Executive Vice President, General Counsel and Corporate Secretary, CH2M HILL Companies, Ltd., 9191 South Jamaica Street, Englewood, Colorado 80112.

CH2M 2016 Proxy Statement    55

General Information

What is the purpose of the annual meeting?

At our annual meeting, stockholders have the opportunity to vote on the matters included in this proxy statement.

Who can attend the meeting?

All stockholders of record as of March 11, 2016, or their duly appointed proxies may attend the meeting.

Who is entitled to vote?

You are entitled to vote if our records show that you held your shares of CH2M common stock or Series A Preferred Stock ("preferred stock") at the close of business on March 11, 2016. This date is known as the "record date" for determining who receives notice of the annual meeting and who is entitled to vote. The holders of common stock are entitled to one vote per share, and the holders of preferred stock are entitled to one vote for each share of common stock into which the preferred stock is convertible. The holders of shares of common stock and preferred stock will vote together as a single class on all matters to be considered at the annual meeting.

What constitutes a quorum?

The presence in person or by proxy of the holders of a majority of the aggregate voting power of all of the shares of common stock and preferred stock issued and outstanding and entitled to vote at the meeting constitutes a quorum. As of the record date, 26,447,758 shares of common stock and 3,214,400 shares of preferred stock were outstanding and entitled to vote, and the holders of the preferred stock were entitled to vote an additional 83,578 shares relating to accrued dividends on the preferred stock. Proxies received but marked as abstentions will be included in the calculation of the number of shares considered to be present at the meeting for purposes of determining a quorum.

How do I vote?

If you are a holder of record of CH2M shares of common stock or preferred stock as of March 11, 2016, you can vote in one of four ways:

1.

Vote by Internet — follow the instructions on the Internet at www.envisionreports.com/ch2m.

2.

Vote by phone — call 1 (800) 652-8683 (in the U.S., U.S. territories and Canada) or (781) 575-2300 (outside the U.S., U.S. territories and Canada).

3.

Vote by proxy card — if you have requested and received a paper copy of the proxy materials, you can mark, sign, date and return the paper proxy card enclosed with the proxy materials using the instructions on the paper proxy card; please note that if you vote through the Internet or by phone, you do not need to return your proxy card.

4.

Vote in person — if you attend the annual meeting, you may deliver your completed proxy card in person or vote in person by completing the ballot form that will be provided.

Why did I receive more than one set of proxy materials?

You may receive multiple sets of proxy materials if you hold your CH2M shares in multiple ways, such as directly as a holder of record and indirectly through the CH2M HILL Retirement and Tax Deferred Savings Plan.

If you hold your CH2M shares in multiple ways, you should vote your shares as described in each separate set of proxy materials you receive.

56     CH2M 2016 Proxy Statement

Can I change my vote or revoke my proxy?

Yes. Even after you have submitted your proxy, you may change your vote at any time before the proxy is exercised by filing with the Corporate Secretary of CH2M at 9191 South Jamaica Street, Englewood, CO 80112 either a notice of revocation or a duly executed proxy bearing a later date as long as it is received by May 10, 2016, at 11:00 a.m., Eastern Daylight Time. Your proxy also will be revoked if you attend the meeting in person and so request, although attendance at the meeting will not by itself revoke a previously granted proxy.

How do I vote my 401(k) Plan shares?

If you participate in the CH2M HILL Retirement and Tax-Deferred Savings Plan, you have the right, if you choose, to instruct the trustees of the Plan how to vote the shares of common stock credited to your Plan account. Your instructions to the trustees of the Plan should be made by voting as explained above. The trustees of the Plan will vote your shares in accordance with your duly executed instructions which must be received by the trustees no later than 11:59 p.m., Eastern Daylight Time, on May 3, 2016. If you do not send instructions regarding the voting of common stock credited to your Plan account, such shares shall be voted by the trustees of the Plan in accordance with their determination of the interests of the Plan participants and the Plan as a whole. You may revoke previously given instructions by filing with the trustees of the Plan no later than 11:59 p.m., Eastern Daylight Time, on May 3, 2016, either written notice of revocation or a properly completed and signed voting instruction bearing a date later than the date of the prior instructions.

How do I provide input for my Canadian E-Shares or International Share Value Equivalent Units (ISVEUs)?

If you are a holder of Canadian E-Shares or ISVEUs, you may provide your input by following the voting instructions discussed above. Neither Canadian E-Shareholders nor ISVEU holders have a vote on the issues addressed at the meeting. However, the input of Canadian E-Shareholders will be considered on all items being voted on by stockholders, and the ISVEU trustees will consider the input of ISVEU holders and take it into account when voting the shares held in the ISVEU trusts. To be considered, your input must be received no later than 11:59 p.m., Eastern Daylight Time, on May 3, 2016.

How will my proxy be voted?

The persons named as proxy holder on the proxy card will vote in accordance with your instructions or, if none are provided, "FOR" each director nominee named in this proxy statement and "FOR" ratification of the appointment of KPMG LLP as our independent auditors for the fiscal year ending December 30, 2016, in accordance with the recommendations of the Board of Directors. With respect to any other matter that properly comes before the meeting, the proxy holders will vote as recommended by the Board of Directors or, if no recommendation is given, in their own discretion. All votes will be tabulated by the inspector of election appointed for the meeting, who will separately tabulate affirmative and negative votes and abstentions.

How many votes are required for each proposal?

For Proposal 1, the votes cast "FOR" each director nominee must exceed the votes cast "AGAINST" the nominee to elect the nominee as a director. For Proposal 2, the votes cast "FOR" must exceed the votes cast "AGAINST" to approve the ratification of KPMG LLP as CH2M's independent auditors.

How are abstentions treated?

A properly executed proxy marked "ABSTAIN" with respect to any matter will not be voted on that matter, although it will be counted for purposes of determining whether there is a quorum. The proposals will be determined by a majority of votes cast. Accordingly, an abstention vote will have no effect on the outcome of the proposals.

How will proxies be solicited?

Proxies are being solicited by the Board on behalf of CH2M. Proxies may be solicited by officers, directors and employees of CH2M, none of whom will receive any additional compensation for their services. These solicitations may be made personally or by mail, facsimile, telephone, email or the Internet. The cost of solicitation of the proxies will be paid by CH2M. CH2M has no plans to retain any firms or otherwise incur any extraordinary expense in connection with the solicitation.

TAX-DEFERRED SAVINGS PLAN PLEASE DISREGARD THIS LETTER

CH2M HILL Companies, Ltd.
Participant Notice
Retirement and Tax-Deferred Savings Plan

March 16, 2016

Dear Plan Participant:

The enclosed Proxy Statement has been furnished by CH2M HILL Companies, Ltd. in conjunction with the Annual Meeting of Stockholders of CH2M HILL Companies, Ltd. to be held on May 10, 2016, to elect directors and to conduct other business.

While only the Trustee of the CH2M HILL Companies, Ltd. Retirement and Tax-Deferred Savings Plan can vote the shares of CH2M HILL Companies, Ltd. stock (Company Stock) held in the Plan, you, as a participant or a beneficiary with Company Stock credited to your account under the Plan as of March 11, 2016 (the record date for the annual meeting), and a named fiduciary under the Plan, are entitled to instruct the Trustee of the Plan with respect to the voting of Company Stock allocated to your account under the Plan on the record date. The Trustee will vote the Company Stock credited to your account in accordance with your instructions, provided that the Trustee determines it can do so in accordance with the Employee Retirement Income Security Act of 1974 (ERISA).

A named fiduciary is a person who under ERISA has the authority and responsibility (if he or she chooses to exercise it) to instruct the trustee of a plan regarding specific investments. Consequently, because of the provisions of the Plan, the Plan participant as a named fiduciary may (if he or she chooses) instruct the Trustee of the Plan as to how to vote shares of Company Stock allocated to his or her own Plan account.

If you do not send instructions regarding the voting of Company Stock credited to your Plan account, or if your instructions are not received in a timely manner, such shares shall be voted by the Trustee of the Plan in accordance with the interests of the Plan participants and the Plan as a whole, as determined by the Trustee. If the voting instruction form is received after 11:59 p.m., Eastern Daylight Time, on May 3, 2016, the Trustee cannot ensure that your voting instructions will be followed.

The Trustee of the Plan will vote uninstructed Company Stock in accordance with the interests of the Plan participants and the Plan as a whole, as determined by the Trustee. In all events, the Trustee will comply with ERISA in voting shares of Company Stock.

It should be noted that your instructions to the Trustee are strictly confidential. Under no circumstances will the Trustee or any of his or her agents disclose to CH2M HILL Companies, Ltd. or any other party how, or if, you voted. The Trustee will supervise and control the distribution of all materials to Plan participants and the receipt of all voting instruction forms and will not disclose to any outside party the name and address of any Plan participant. You may, therefore, feel completely free to instruct the Trustee to vote these shares in the manner you think best.

If you have any questions regarding the information provided to you, you may contact Erik Ammidown, Plan Administrator, 9191 South Jamaica Street, Englewood, CO 80112, (720) 286-0163.
