Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the normal course of business, we are subject to certain contractual guarantees, claims and litigation. The guarantees to which we are a party generally relate to project schedules and plant performance. Most of the claims and litigation in which we are involved has us as a defendant in workers' compensation; personal injury; environmental; employment/labor; professional liability; and other similar matters. We maintain insurance coverage for various aspects of our business and operations. Our insurance programs have varying coverage limits and maximums, and insurance companies may and increasingly do seek to not pay any claims we might make. We have also elected to retain a portion of losses that occur through the use of various deductibles, limits, and retentions under our insurance programs. As a result, we may be subject to future liability for which we are only partially insured or completely uninsured. We intend to mitigate any such future liability by continuing to exercise prudent business judgment in negotiating the terms and conditions of our contracts. Our insurers are also subject to business risk and, as a result, one or more of them may be unable to fulfill their insurance obligations due to insolvency or otherwise. Additionally, as a contractor providing services to the U.S. federal government and several of its agencies, we are subject to many levels of audits, investigations, and claims by, or on behalf of, the U.S. federal government with respect to our contract performance, pricing, costs, cost allocations, and procurement practices. Furthermore, our income, franchise, and similar tax returns and filings are also subject to audit and investigation by the Internal Revenue Service, most states within the U.S. as well as by various government agencies representing jurisdictions outside the U.S. We record in our Consolidated Balance Sheets amounts representing our estimated liability relating to such claims, guarantees, litigation, and audits and investigations. We perform an analysis to determine the level of reserves to establish for claims that may be insured that are known and have been asserted against us, and for claims that may be insured that are believed to have been incurred based on actuarial analysis, but have not yet been reported to our claims administrators as of the respective balance sheet dates. We include any adjustments to such insurance reserves in our consolidated results of operations. Management believes, after consultation with counsel, that such guarantees, litigation, U.S. government contract-related audits, investigations and claims, and income tax audits and investigations should not have any material adverse effect on our consolidated financial statements. On August 9, 2014, the Company received a Notice of Arbitration from Motiva Enterprises LLC. The arbitration is pending in Houston, Texas before the International Institute for Conflict Prevention and Resolution. In 2006, Motiva contracted with Bechtel-Jacobs CEP Port Arthur Joint Venture (“BJJV”), a joint venture between Bechtel Corporation and Jacobs Engineering Group, Inc. to perform professional services in connection with the expansion project at the Motiva Port Arthur, TX refinery. In the Notice of Arbitration, Motiva asserts various causes of action and alleges entitlement to equitable and monetary relief in excess of $7 billion.
