Recent Accounting Pronouncements [Abstract]
Intangibles Goodwill and Other	In September 2011, the FASB issued revised guidance FASB ASU 2011-08, “Intangibles – Goodwill and Other (Topic 350) - Testing Goodwill for Impairment” to allow entities to use a qualitative approach to test goodwill for impairment. The amendment permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform the currently prescribed two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted and the Company has chosen early adoption. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.
Testing Indefinite Lived Assets for Impairment	In July 2012, the FASB issued revised guidance FASB ASU 2012-02, “Testing Indefinite Lived Assets for Impairment” to allow entities to consider qualitative values in determining whether or not indefinite lived assets should be tested for impairment. If it is more likely than not that impairment exists, testing for impairment should be performed. The update is effective for fiscal years beginning after September 15, 2012 but early adoption is permitted. Management believes that the adoption of this guidance will not have a material impact on the Company’s consolidated financial statements.
Revenue Recognition	Costs and estimated earnings in excess of billings are the results of contracts in progress (jobs) in completing orders to customers’ specifications on contracts accounted for under FASB ASC 605-35, “Revenue Recognition: Construction-Type and Production-Type Contracts.” Costs included are material, labor, and overhead. These jobs require design and engineering effort for a specific customer purchasing a unique product. The Company records revenue on these fixed-price and cost-plus contracts on the percentage of completion basis using the ratio of costs incurred to estimated total costs at completion as the measurement basis for progress toward completion and revenue recognition. Any losses identified on contracts are recognized immediately. Contract accounting requires significant judgment relative to assessing risks, estimating contract costs and making related assumptions for schedule and technical issues. With respect to contract change orders, claims, or similar items, judgment must be used in estimating related amounts and assessing the potential for realization. These amounts are only included in contract value when they can be reliably estimated and realization is probable. Billings are generated based on specific contract terms, which might be a progress payment schedule, specific shipments, etc. None of the above contracts in progress contain post-shipment obligations.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
