Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies The Company is involved in claims and lawsuits incidental to our business arising from various matters including commercial disputes, alleged product defect and/or warranty claims, intellectual property matters, personal injury claims, environmental issues, employment and/or workplace-related matters, and various governmental regulations. The Company evaluates its exposure to such claims and suits periodically and establishes accruals for these contingencies when a range of loss can be reasonably estimated. The range of reasonably possible losses for such matters, taking into consideration our rights in indemnity and recourse to third parties is $1.2 million to $10.8 million. At June 30, 2019, total accruals of $4.8 million, including environmental matters described below, are included in accrued liabilities in the accompanying Consolidated Balance Sheet. The Company believes any additional liability would not be material to its financial position or results of operations. Arcosa is subject to remedial orders and federal, state, local, and foreign laws and regulations relating to the environment. The Company has reserved $1.0 million as of June 30, 2019, included in our total accruals of $4.8 million discussed above, to cover our probable and estimable liabilities with respect to the investigations, assessments, and remedial responses to such matters, taking into account currently available information and our contractual rights to indemnification and recourse to third parties. However, estimates of liability arising from future proceedings, assessments, or remediation are inherently imprecise. Accordingly, there can be no assurance that we will not become involved in future litigation or other proceedings involving the environment or, if we are found to be responsible or liable in any such litigation or proceeding, that such costs would not be material to the Company.
