Notes to Financial Statements [Abstract]	'
BUSINESS, BASIS OF PRESENTATION, AND ACCOUNTING POLICIES	'
	NOTE 1. BUSINESS, BASIS OF PRESENTATION, AND ACCOUNTING POLICIES
	Overview
	The accompanying unaudited condensed consolidated financial statements and related notes have been prepared in accordance with generally accepted accounting principles (“GAAP”) in the U.S. for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.
	You should read our unaudited condensed consolidated financial statements in conjunction with the audited consolidated financial statements and related notes contained in our Revised Form 10-K for our fiscal year ended January 3, 2014, which was attached as Exhibit 99.1 to our Current Report on Form 8-K (“Current Report on Form 8-K”) filed on August 1, 2014, as amended. The results of operations for the three and six months ended July 4, 2014 are not indicative of the operating results for the full year or for future years.
	In our opinion, the accompanying unaudited condensed consolidated financial statements reflect all normal and recurring adjustments that are necessary for a fair statement of our financial position, results of operations and cash flows for the interim periods presented.
	Pending Merger
	On July 11, 2014, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with AECOM Technology Corporation (“AECOM”), ACM Mountain I, LLC, a direct wholly-owned subsidiary of AECOM (“Merger Sub”), and ACM Mountain II, LLC, a direct wholly-owned subsidiary of AECOM (“Merger Sub I”). The Merger Agreement provides for the merger of Merger Sub with and into our company, with our company continuing as the surviving company and a direct wholly-owned subsidiary of AECOM (the “Merger”). Immediately thereafter, as part of a single integrated transaction with the Merger, pursuant to the Merger Agreement, we will merge with and into Merger Sub I, with Merger Sub I continuing as the surviving company and a direct wholly-owned subsidiary of AECOM. Subject to the terms and conditions of the Merger Agreement, holders of URS common stock will receive consideration to be determined at closing based on the average closing price of AECOM common stock during the five business days prior to the closing date. Each outstanding share of URS common stock will be exchanged for per share consideration consisting of 0.734 shares of AECOM common stock and $33.00 in cash. URS stockholders may elect to receive cash or stock consideration, subject to proration in the event of oversubscription or undersubscription for cash consideration.
	Completion of the Merger is subject to certain customary conditions, including approval by both the AECOM and URS stockholders, approval of the listing of the shares of AECOM common stock to be issued in the Merger on the New York Stock Exchange, receipt of required regulatory approvals and/or expiration or termination of applicable waiting periods, effectiveness of AECOM’s registration statement on Form S-4 and receipt of customary opinions related to certain tax matters from the parties’ respective counsels. On August 4, 2014, the Federal Trade Commission granted URS and AECOM early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. The financial statements included in this Quarterly Report on Form 10-Q do not reflect any adjustments or otherwise give effect to the proposed Merger.
	Principles of Consolidation and Basis of Presentation
	Our condensed consolidated financial statements include the financial position, results of operations and cash flows of URS Corporation and our majority-owned subsidiaries and joint ventures that are required to be consolidated.
	Investments in unconsolidated joint ventures are accounted for using the equity method and are included as “Investments in and advances to unconsolidated joint ventures” on our Condensed Consolidated Balance Sheets. All significant intercompany transactions and accounts have been eliminated in consolidation
	Use of and Changes in Estimates
	The preparation of our unaudited condensed consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and related disclosures at the balance sheet dates, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, we review our estimates based on information that is currently available. Changes in facts and circumstances may cause us to revise our estimates.
	Our business activities involve making significant estimates and assumptions in the normal course of business relating to our contracts. We focus on evaluating the performance of contracts individually.  These estimates and assumptions can vary in the normal course of business as contracts progress, when estimated productivity assumptions change based on experience to-date and as uncertainties are resolved. We use the cumulative catch-up method applicable to construction contract accounting to account for revisions in estimates.
	There were no material changes in estimates for the three and six months ended July 4, 2014.
	During the six months ended June 28, 2013, our results of operations included the recognition of $26 million of performance-based incentive fees from our work managing chemical demilitarization programs.  These changes in estimates resulted in increases of $26 million in operating income, $16 million in net income and $0.21 in diluted earnings per common share (“diluted EPS”) for the six months ended June 28, 2013. There were no material changes in estimates for the three months ended June 28, 2013.

Notes to Financial Statements [Abstract]	'
ADOPTED AND OTHER RECENTLY ISSUED STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS	'
	NOTE 2. ADOPTED AND OTHER RECENTLY ISSUED STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS
	From time to time, the Financial Accounting Standards Board (“FASB”) issues accounting standards updates (each being an “ASU”) to its Accounting Standards Codification (“ASC”), which constitutes the primary source of U.S. GAAP.  We regularly monitor ASUs as they are issued and consider their applicability to our business.  All applicable ASUs are adopted by the due date and in the manner prescribed by the FASB.  ASUs adopted during the six months ended July 4, 2014 did not have a material impact on our condensed consolidated financial statements.
	In April 2014, the FASB issued an ASU related to discontinued operations.  This ASU more narrowly defines discontinued operations as disposals of components of an entity, or groups of components, that represent a strategic shift that has or will have a major effect on an entity’s operations in the financial statements.  It requires additional disclosures about discontinued operations, as well as disclosures about disposals of individual significant components of an entity that do not qualify as discontinued operations.  This standard will be effective beginning with our first interim period in fiscal year 2015, with an option for early adoption.  We are evaluating the potential effects of the adoption of this ASU on our future consolidated financial statements.
	In May 2014, the FASB issued an ASU related to revenue recognition, which provides a new principle-based model of revenue recognition that will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of this ASU is that an entity should recognize revenues when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU also requires additional disclosures about the nature, amount, timing, and uncertainty of revenues and cash flows arising from customer contracts. This ASU will be effective beginning with our first interim period in fiscal year 2017. Early adoption is not permitted. The ASU allows for either full retrospective or modified retrospective adoption. We are evaluating the transition method that will be elected and the potential effects of the adoption of this ASU on our consolidated financial statements.

	NOTE 3. EARNINGS PER SHARE
	In our computation of diluted EPS, we exclude the potential shares related to nonvested restricted stock awards and units that have an anti-dilutive effect on EPS or that currently have not met performance conditions. For the three and six months ended July 4, 2014, there were no potential shares related to nonvested restricted stock awards that would have an anti-dilutive effect. For the three and six months ended June 28, 2013, potential shares that had an anti-dilutive effect were 0.6 million and 0.3 million shares, respectively.
	The following table summarizes the components of weighted-average common shares outstanding for both basic and diluted EPS:

JOINT_VENTURES

JOINT VENTURES	6 Months Ended
	Jul. 04, 2014
Notes to Financial Statements [Abstract]	'
JOINT VENTURES	'
	NOTE 5. JOINT VENTURES
	We analyze all of our joint ventures and classify them into two groups:
	Joint ventures that must be consolidated either because they are not variable interest entities (“VIEs”) and we hold the majority voting interest, or because they are VIEs of which we are the primary beneficiary; and
	Joint ventures that do not need to be consolidated either because they are not VIEs and we do not hold a majority voting interest, or because they are VIEs of which we are not the primary beneficiary.
	We perform a quarterly review of our joint ventures to determine whether there were any changes in the status of the VIEs or changes to the primary beneficiary designation of each VIE. We determined that no such changes occurred during the six months ended July 4, 2014.
	In the table below, we have aggregated financial information relating to our VIEs because their nature and risk and reward characteristics are similar. None of our current joint ventures that meets the characteristics of a VIE is individually significant to our consolidated financial statements.
						July 4,		January 3,

					Total liabilities and owners’ equity	$	454	$	435
	Total revenues of the consolidated joint ventures were $296 million and $275 million for the three months ended July 4, 2014 and June 28, 2013, respectively, and $517 million and $529 million for the six months ended July 4, 2014 and June 28, 2013, respectively.
	The assets of our consolidated joint ventures are restricted for use only by the particular joint venture and are not available for our general operations.
	Unconsolidated Joint Ventures
	We use the equity method of accounting for our unconsolidated joint ventures. Under the equity method, we recognize our proportionate share of the net earnings of these joint ventures as a single line item under “Equity in income of unconsolidated joint ventures” in our Condensed Consolidated Statements of Operations.
	The table below presents financial information, derived from the most recent financial statements provided to us, in aggregate, for our unconsolidated joint ventures:

		Revenues	$	1,112
		Cost of revenues	$	-994
		Income from continuing operations before tax	$	118
		Net income	$	110
	Income from unconsolidated U.S. joint ventures is generally not taxable in most tax jurisdictions in the U.S. The tax expenses on our other unconsolidated joint ventures are primarily related to foreign taxes.
	We received $25 million and $29 million, respectively, of distributions from unconsolidated joint ventures for the three months ended July 4, 2014 and June 28, 2013 and $44 million and $52 million, respectively, for the six months ended July 4, 2014 and June 28, 2013.
	Exposure to Loss
	In addition to potential losses arising out of the carrying values of the assets and liabilities of our unconsolidated joint ventures, our maximum exposure to loss also includes performance assurances and guarantees we sometimes provide to clients on behalf of joint ventures that we do not directly control. We enter into these guarantees primarily to support the contractual obligations associated with the joint ventures’ projects. The potential payment amount of an outstanding performance guarantee is typically the remaining cost of work to be performed by or on behalf of third parties under engineering and construction contracts.
However, the majority of the unconsolidated joint ventures in which we participate involve cost-reimbursable, level-of-effort projects that are accounted for as service-type projects, not engineering and construction projects that would follow the percentage-of-completion or completed-contract accounting method. Revenues for service-type contracts are recognized in proportion to the number of service activities performed, in proportion to the direct costs of performing the service activities, or evenly across the period of performance, depending upon the nature of the services provided. The services we provide on these cost-reimbursable contracts are management and operations services for government clients and operations and maintenance services for non-government clients. We believe that, due to the continual changes we experience in client funding and scope definitions, reliable estimates of performance guarantees cannot be calculated because they cannot be reliably predicted. In addition, we participate in joint ventures in which the level of our participation is so minimal that we do not have access to those joint ventures’ estimates to complete. The joint ventures where we perform engineering and construction contracts and where we have access to the estimates to complete, which are needed to calculate the performance guarantees, are immaterial.

GOODWILL	'
	NOTE 6. GOODWILL
	Interim Goodwill Impairment Review
	Based on the implied value of the potential Merger with AECOM to URS stockholders, we performed an interim goodwill impairment test as of July 4, 2014 for all of our seven reporting units. A goodwill impairment review involves a two-step process. The first step is a comparison of each reporting unit’s fair value to its carrying value. If the carrying value of the reporting unit is higher than its fair value, there is an indication that an impairment may exist and the second step must be performed to measure the amount of the impairment.
	In reaching our estimate of fair value, we considered the fair values derived from using both the income and market approaches. We gave primary weight to the income approach because it was deemed to be the most applicable. The fair value measurements from the income approach were calculated using unobservable inputs to our discounted cash flows, which inputs are classified as Level 3 within the fair value hierarchy. The income approach uses a reporting unit’s projection of estimated cash flows and discounts those back to the present using a weighted-average cost of capital that reflects current market conditions. To arrive at the cash flow projections used in the calculation of fair values for our goodwill impairment review, we use market participant estimates of economic and market activity for the next ten years. The key assumptions we used to estimate the fair values of our reporting units are:
	Revenue growth rates;
	Operating margins;
	Capital expenditure needs;
	Working capital requirements;
	Discount rates; and
	Terminal value capitalization rate (“Capitalization Rate”)
	Of the key assumptions, the discount rates and the Capitalization Rate are market-driven. These rates are derived from the use of market data and employment of the weighted-average cost of capital. The key assumptions that are company-driven include the revenue growth rates and the projected operating margins. They reflect the influence of other potential assumptions, since the assumptions we identified that affect the projected operating results would ultimately affect either the revenue growth or the profitability (operating margin) of the reporting unit. For example, any adjustment to contract volume and pricing would have a direct impact on revenue growth, and any adjustment to the reporting unit’s cost structure or operating leverage would have a direct impact on the profitability of the reporting unit. Actual results may differ from those assumed in our forecasts and changes in assumptions or estimates could materially affect the determination of the fair value of a reporting unit, and therefore could affect the amount of potential impairment.
	We also consider indications obtained from the market approach. We applied market multiples derived from stock market prices of companies that are engaged in the same or similar lines of business as our reporting units and that are actively traded on a free and open market, and applied market multiples derived from transactions of significant interests in companies engaged in the same or similar lines of business as our reporting units and a control premium to arrive at the fair values.
	When performing our impairment analysis, we also reconcile the sum of the fair values of our reporting units with our market capitalization to determine if the sum reasonably reconciles with the external market indicators. If our reconciliation indicates a significant difference between our external market capitalization and the sum of the fair values of our reporting units, we review and adjust the assumptions employed in our analysis, and examine if the implied control premium is reasonable in light of current market conditions.
	Goodwill is allocated to the reporting units based on the respective fair values of the reporting units at the time of the various acquisitions that gave rise to the recognition of goodwill or at the time of a reorganization that impacts the composition of the reporting units.
	We performed the first step of the analysis to compare the fair value of each reporting unit to its carrying amount. Based on the analysis performed, the fair values of all of our reporting units exceeded their respective carrying values, indicating that no impairment exists, and therefore the second step of the analysis was not deemed necessary.
	Below is a table showing, for each reporting unit, the percentage of its fair value that exceeded its carrying value:

	2011 Credit Facility
	As of both July 4, 2014 and January 3, 2014, the outstanding balance of the term loan under our senior credit facility (“2011 Credit Facility”) was $605 million. As of July 4, 2014 and January 3, 2014, the interest rates applicable to the term loan were 1.68% and 1.67%, respectively. Loans outstanding under our 2011 Credit Facility bear interest, at our option, at the base rate or at LIBOR plus, in each case, an applicable per annum margin. The applicable margin is determined based on the better of our debt ratings or our leverage ratio in accordance with a pricing grid. The interest rate at which we normally borrow is LIBOR plus 150 basis points.
	We were in compliance with the covenants of our 2011 Credit Facility as of July 4, 2014.
	As of both July 4, 2014 and January 3, 2014, the estimated fair market value of the term loan under our 2011 Credit Facility was approximately $603 million. The carrying value of this term loan on our Condensed Consolidated Balance Sheets as of both July 4, 2014 and January 3, 2014 was $605 million, excluding unamortized issuance costs. The fair value of our term loan as of July 4, 2014 was derived by taking the mid-point of the trading prices from an observable market input (Level 2) in the secondary loan market and multiplying it by the outstanding balance of our term loan. The fair value of our term loan as of January 3, 2014 was determined to be at par less issuance fees as the agreement was amended on December 19, 2013 (Level 2).
	Senior Notes
	On March 15, 2012, URS Corporation, the parent company (“Parent”), and URS Fox US LP (“Fox LP”), a 100% owned subsidiary of Parent issued, in a private placement, $400 million aggregate principal amount of 3.85% Senior Notes due on April 1, 2017 and $600 million aggregate principal amount of 5.00% Senior Notes due on April 1, 2022. Substantially all of the Senior Notes were exchanged for new Senior Notes registered under the Securities Act of 1933, as amended, as of January 9, 2014 (collectively, the “Senior Notes”). As of July 4, 2014, the outstanding balance of the Senior Notes was $999 million, net of $1 million of discount.
	The Senior Notes are our general unsecured senior obligations and rank equally with our other existing and future unsecured senior indebtedness. The Senior Notes are fully and unconditionally guaranteed (each a “Guarantee” or, collectively, the “Guarantees”) on a joint-and-several basis by each of our current and future domestic subsidiaries that are guarantors under our 2011 Credit Facility or that are 100% owned domestic obligors or 100% owned domestic guarantors, individually or collectively, under any future indebtedness of our subsidiaries in excess of $100 million (the “Guarantors”). The Guarantees are the Guarantors’ unsecured senior obligations and rank equally with the Guarantors’ other existing and future unsecured senior indebtedness.
	The Guarantee of a Guarantor will, so long as no event of default shall have occurred and be continuing with respect to the Senior Notes, be automatically and unconditionally released and discharged without any action on the part of the trustee or the holders of the Senior Notes:
	with respect to a Guarantor which, individually or together with the Parent’s other domestic subsidiaries, no longer has any indebtedness of borrowed money in excess of $100 million outstanding and no longer guarantees, individually or together with the Parent’s other domestic subsidiaries, any indebtedness in excess of $100 million incurred by the Parent or any of the Parent’s other 100% owned domestic subsidiaries;
	unless the Guarantor is the surviving entity (i) upon the sale, lease or exchange of all or substantially all of the Guarantor’s assets to any person or entity not an affiliate of the Parent or (ii) upon any sale, exchange or transfer, to any person or entity not an affiliate of the Parent, of all of the Parent’s direct and indirect interest in such Guarantor;
	upon the full and final payment and performance of all obligations under the indenture and the Senior Notes;
	upon liquidation and dissolution of a Guarantor in a transaction that is not prohibited by the indenture; or
	upon legal defeasance, covenant defeasance or satisfaction and discharge of the indenture.
	In addition, the Guarantee of any domestic subsidiary that is a Guarantor will be automatically and unconditionally released and discharged, without any further action required by such Guarantor, the trustee, or the holders of the Senior Notes, if at any time such domestic subsidiary of the Parent that is a Guarantor is no longer a domestic subsidiary of the Parent.
	We were in compliance with the covenants of our Senior Notes as of July 4, 2014.
	As of July 4, 2014 and January 3, 2014, the estimated fair market values of the Senior Notes were approximately $1 billion and $983 million, respectively. The carrying value of the Senior Notes on our Condensed Consolidated Balance Sheets as of both July 4, 2014 and January 3, 2014 was $1 billion, excluding unamortized discount. The fair value of the Senior Notes was derived by taking quoted prices of comparable bonds and making an adjustment to reflect our credit to determine the price of the Senior Notes (Level 2) in the trading market and multiplying it by the outstanding balance of the notes.
	Revolving line of credit
	Our revolving line of credit is used to fund daily operating cash needs and to support our standby letters of credit. In the ordinary course of business, the use of our revolving line of credit is a function of collection and disbursement activities. Our daily cash needs generally follow a predictable pattern that parallels our payroll cycles, which dictate, as necessary, our short-term borrowing requirements.
	As of July 4, 2014, we had an outstanding balance of $84 million on our revolving line of credit. We had no outstanding debt balances on our revolving line of credit as of January 3, 2014. As of July 4, 2014, we had issued $98 million of letters of credit, leaving $818 million available under our revolving credit facility.
	Other Indebtedness
	Our other indebtedness included notes payable and capital leases for office equipment, computer equipment, furniture, vehicles and automotive equipment, and construction equipment, five-year loan notes, and foreign lines of credit. As of July 4, 2014 and January 3, 2014, we maintained several credit lines with an aggregate borrowing capacity of $47 million and $51 million, respectively, and had remaining borrowing capacity of $46 million and $49 million, respectively.

	NOTE 15. SEGMENT AND RELATED INFORMATION
	We operate our business through the following four segments:
	Our Infrastructure & Environment Division provides program management, planning, design, engineering, construction and construction management, operations and maintenance, and decommissioning and closure services to the U.S. federal government, state and local government agencies, and private sector clients in the U.S. and internationally.
	Our Federal Services Division provides services to a wide variety of U.S. federal government agencies, as well as to national governments in other countries. This includes program management, planning, design, engineering, systems engineering and technical assistance, construction and construction management, operations and maintenance, management and operations, IT, and decommissioning and closure services.
	Our Energy & Construction Division provides program management, planning, design, engineering, construction and construction management, operations and maintenance, and decommissioning and closure services to private sector clients as well as federal, state, and local government agencies.
	Our Oil & Gas Division provides services to oil and gas industry clients throughout the U.S. and Canada. This includes oilfield services, such as rig transportation and fluid hauling; oil and gas production services, including mechanical, electrical and instrumentation services; pipeline and facility construction; engineering; and maintenance services.
	These four segments operate under separate management groups and produce discrete financial information. Their operating results also are reviewed separately by management. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies in our Current Report on Form 8-K. The information disclosed in our condensed consolidated financial statements is based on the four segments that compose our current organizational structure.
	Effective with the beginning of our fiscal year 2014, we realigned our Global Management and Operations Services Group, which was previously a component of our Energy & Construction Division, under the operations and management of our Federal Services Division. The realignment of this group consolidated the majority of our business with U.S. federal government agencies and national governments outside the U.S. in our Federal Services Division. We also realigned a portion of our facility construction, process engineering, and operations and maintenance services to the oil and gas industry among our Oil & Gas, Infrastructure & Environment, and Energy & Construction Divisions. These changes, which restructured elements of our oil and gas business from an organization based on legacy acquisitions to one based on service, are designed to improve our ability to provide integrated services to our oil and gas clients. To reflect these realignments, we have revised the prior year amounts to conform to our current year presentation.
	The following table presents summarized financial information for our reportable segments. “Inter-segment, eliminations and other” in the following table includes eliminations of inter-segment sales and investments in subsidiaries. The segment balance sheet information presented below is included for informational purposes only. We do not allocate resources based upon the balance sheet amounts of individual segments. Our long-lived assets consist primarily of property and equipment.

Major Customers and Other
Our largest clients are from our federal market sector. Within this sector, we have multiple contracts with our two major customers: the U.S. Army and the DOE. For the purpose of analyzing revenues from major customers, we do not consider the combination of all federal departments and agencies as one customer. The different federal agencies manage separate budgets. As such, reductions in spending by one federal agency do not affect the revenues we could earn from another federal agency. In addition, the procurement processes for federal agencies are not centralized, and procurement decisions are made separately by each federal agency. The loss of the federal government, the U.S. Army, or DOE as clients would have a material adverse effect on our business.
Our revenues from the U.S. Army and DOE by division for the three and six months ended July 4, 2014 and June 28, 2013 are presented below:

COMMITMENTS AND CONTINGENCIES	'
	NOTE 13. COMMITMENTS AND CONTINGENCIES
	In the ordinary course of business, we and our affiliates are subject to various disputes, audits, investigations and legal proceedings. Additionally, as a government contractor, we are subject to audits, investigations, and claims with respect to our contract performance, pricing, costs, cost allocations, and procurement practices. The final outcomes of these various matters cannot be predicted or estimated with certainty. We are including information regarding the following matters:
	USAID Egyptian Projects: In March 2003, Washington Group International, Inc., a Delaware company (“WGI Delaware”), our wholly owned subsidiary, was notified by the Department of Justice that the federal government was considering civil litigation against WGI Delaware for potential violations of the U.S. Agency for International Development (“USAID”) source, origin, and nationality regulations in connection with five of WGI Delaware’s USAID-financed host-country projects located in Egypt beginning in the early 1990s. In November 2004, the federal government filed an action in the United States District Court for the District of Idaho against WGI Delaware, Contrack International, Inc., and MISR Sons Development S.A.E., an Egyptian construction company, asserting violations under the Federal False Claims Act, the Federal Foreign Assistance Act of 1961, as well as common law theories of payment by mistake and unjust enrichment. The federal government seeks damages and civil penalties (including doubling and trebling of damages) for violations of the statutes as well as a refund of the approximately $373 million paid to WGI Delaware under the specified contracts. WGI Delaware has denied any liability in the action and contests the federal government’s damage allegations and its entitlement to recovery. All USAID projects under the contracts have been completed and are fully operational.
	In March 2005, WGI Delaware filed motions in Idaho District Court and the United States Bankruptcy Court in Nevada contending that the federal government’s Idaho action is barred under the plan of reorganization approved by the Bankruptcy Court in 2002 when WGI Delaware emerged from bankruptcy protection. In 2006, the Idaho action was stayed pending the bankruptcy-related proceedings. On April 24, 2012, the Bankruptcy Court ruled that the bulk of the federal government’s claims under the False Claims and the Federal Foreign Assistance Acts are not barred. On November 7, 2012, WGI Delaware appealed the Bankruptcy Court’s decision to the Ninth Circuit Bankruptcy Appellate Panel. On August 2, 2013, the Appellate Panel affirmed the Bankruptcy Court’s decision. On September 26, 2013, WGI Delaware appealed the Appellate Panel’s decision to the United States Ninth Circuit Court of Appeals.
	WGI Delaware intends to continue to defend this matter vigorously; however, WGI Delaware cannot provide assurance that it will be successful in these efforts. The potential range of loss and the resolution of these matters cannot be determined at this time primarily due to the very limited factual record that exists in light of the limited discovery that has been conducted to-date in the Idaho litigation; the fact that the matter involves unique and complex bankruptcy, international, and federal regulatory legal issues; the uncertainty concerning legal theories and their potential resolution by the courts; and the overall age of this matter, as well as a number of additional factors. Accordingly, no amounts have been accrued for the federal government claims in the Idaho action.
	New Orleans Levee Failure Class Action Litigation: From July 1999 through May 2005, Washington Group International, Inc., an Ohio company (“WGI Ohio”), a wholly owned subsidiary acquired by us on November 15, 2007, performed demolition, site preparation, and environmental remediation services for the U.S. Army Corps of Engineers on the east bank of the Inner Harbor Navigation Canal (the “Industrial Canal”) in New Orleans, Louisiana. On August 29, 2005, Hurricane Katrina devastated New Orleans. The storm surge created by the hurricane overtopped the Industrial Canal levee and floodwall, flooding the Lower Ninth Ward and other parts of the city. Fifty-nine personal injury and property damage class action lawsuits were filed in Louisiana State and federal court against several defendants, including WGI Ohio, seeking $200 billion in damages plus attorneys’ fees and costs. Plaintiffs are residents and property owners who claim to have incurred damages from the breach and failure of the hurricane protection levees and floodwalls in the wake of Hurricane Katrina.
	All 59 lawsuits were pleaded as class actions but none have yet been certified as class actions. Along with WGI Ohio, the U.S. Army Corps of Engineers, the Board for the Orleans Levee District, and its insurer, St. Paul Fire and Marine Insurance Company were also named as defendants. At this time WGI Ohio and the Army Corps of Engineers are the remaining defendants. These 59 lawsuits, along with other hurricane-related cases not involving WGI Ohio, were consolidated in the United States District Court for the Eastern District of Louisiana (“District Court”).
	Plaintiffs allege that defendants were negligent in their design, construction and/or maintenance of the New Orleans levees. Specifically, as to WGI Ohio, plaintiffs allege that work WGI Ohio performed adjacent to the Industrial Canal damaged the levee and floodwall, causing or contributing to breaches and flooding. WGI Ohio did not design, construct, repair or maintain any of the levees or the floodwalls that failed during or after Hurricane Katrina. Rather, WGI Ohio performed work adjacent to the Industrial Canal as a contractor for the federal government.
	WGI Ohio filed a motion for summary judgment, seeking dismissal on grounds that government contractors are immune from liability. On December 15, 2008, the District Court granted WGI Ohio’s motion for summary judgment, but several plaintiffs appealed that decision to the United States Fifth Circuit Court of Appeals on April 27, 2009. On September 14, 2010, the Court of Appeals reversed the District Court’s summary judgment decision and WGI Ohio’s dismissal, and remanded the case back to the District Court for further litigation. On August 1, 2011, the District Court decided that the government contractor immunity defense would not be available to WGI Ohio at trial, but would be an issue for appeal. Five of the cases were tried in District Court from September 12, 2012 through October 3, 2012. On April 12, 2013, the District Court ruled in favor of WGI Ohio and the Army Corps of Engineers, finding that the five plaintiffs failed to prove that WGI Ohio’s or the Army Corps of Engineers’ actions caused the failure of the Industrial Canal floodwall during Hurricane Katrina. On July 1, 2013, WGI Ohio filed a motion for summary judgment in District Court to dismiss all other related cases as a result of the District Court’s April 2013 decision. On December 20, 2013, the District Court dismissed the majority of the lawsuits and the remainder of the outstanding claims is being transferred to the District Court for final judgment of dismissal.
	WGI Ohio intends to continue to defend these matters vigorously until all claims are dismissed; however, WGI Ohio cannot provide assurance that it will be successful in these efforts. The potential range of loss and the resolution of these matters cannot be determined at this time primarily due to the likelihood of an appeal; uncertainty concerning legal theories and factual bases that plaintiffs may present and their resolution by courts or regulators; and uncertainty about the plaintiffs’ claims, if any, that might survive certain key motions of our affiliate, as well as a number of additional factors.
	DOE Deactivation, Demolition, and Removal Project: WGI Ohio executed a cost-reimbursable task order with the DOE in 2007 to provide deactivation, demolition and removal services at a New York State project site that, during 2010, experienced contamination and performance issues. In February 2011, WGI Ohio and the DOE executed a Task Order Modification that changed some cost-reimbursable contract provisions to at-risk. The Task Order Modification, including subsequent amendments, requires the DOE to pay all project costs up to $106 million, requires WGI Ohio and the DOE to equally share in all project costs incurred from $106 million to $146 million, and requires WGI Ohio to pay all project costs exceeding $146 million. In addition, in September 2011, WGI Ohio voluntarily paid a civil penalty related to the contamination incident. Through July 4, 2014, WGI Ohio has incurred total project costs of $280 million.
	Due to unanticipated requirements and permitting delays by federal and state agencies, as well as delays and related ground stabilization activities caused by Hurricane Irene, WGI Ohio has been required to perform work outside the scope of the Task Order Modification. In April 2013, WGI Ohio submitted claims against the DOE pursuant to the Contracts Disputes Acts seeking recovery of $118 million in unfunded requests for equitable adjustments (“REAs”), including additional fees on expanded work scope. Through July 4, 2014, the DOE has approved one of the REAs for $1 million and has authorized $34 million of additional funding primarily related to the hurricane-caused impacts. As of July 4, 2014, WGI Ohio has recorded $99 million in accounts receivable for project costs incurred to date in excess of the DOE contracted amount that may not be collected unless and until the claims are favorably resolved. In addition, due to continuing delays and disagreements about the responsibilities for the scope of the remaining project completion costs, WGI Ohio is unable to determine its portion of the remaining project completion costs, which may exceed $300 million.
	WGI Ohio can provide no certainty that it will recover the $118 million in submitted DOE claims and fees incurred through April 2013 related to REAs, hurricane-caused work or other directed changes, as well as any other project costs after April 2013 that WGI Ohio is obligated to incur including the remaining project completion costs, which could negatively impact our future results of operations.
	Bolivian Mine Services Agreement: In 2009, a mine service agreement performed by our wholly owned subsidiary, Washington Group Bolivia, was unilaterally terminated for convenience by the mine owner. The mine owner disputed the fair market value of mining equipment it was required to repurchase under the terms of the mine services agreement. Subsequently, on November 16, 2010, Washington Group Bolivia received a formal claim asserting breaches of contractual obligations and warranties, including the failure to adhere to the requisite professional standard of care while performing the mine services agreement. On June 17, 2011, Washington Group Bolivia received a formal demand for arbitration pursuant to the Rules of Arbitration of the International Chamber of Commerce (“ICC”) asserting claims up to $53 million. Washington Group Bolivia brought a $50 million counterclaim on August 3, 2012 against the mine owner asserting claims of wrongful termination and lost productivity. Arbitration on the mine owner’s claims and Washington Group Bolivia’s counterclaims commenced before the ICC. In the course of the arbitration proceedings, the mine owner reduced its claims to approximately $32 million, while Washington Group Bolivia refined its counterclaim amount to not more than $63 million. On August 9, 2013, an $11 million ICC arbitration tribunal award was issued against Washington Group Bolivia and, on September 5, 2013, the mine owner petitioned the United States District Court of Colorado to confirm the ICC arbitration award. On October 1, 2013, Washington Group Bolivia filed a cross motion to partially vacate the ICC arbitration award in the District Court of Colorado. On February 3, 2014, the District Court of Colorado entered judgment confirming the ICC arbitration award and denied Washington Group Bolivia’s motion to partially vacate the award. Washington Group Bolivia has paid the award, and a satisfaction of judgment was filed by the mine owner with the Court on February 25, 2014.
	We have accrued an estimated probable loss of $11 million related to this matter; however, we expect the loss to be recoverable under our insurance program.
	Canadian Pipeline Contract: In January 2010, a pipeline owner filed an action in the Court of Queen’s Bench of Alberta, Canada against Flint Energy Services Ltd. (“Flint”), a company we acquired in May 2012, as well as against a number of other defendants, alleging that the defendants negligently provided pipe coating and insulation system services, engineering, design services, construction services, and other work, causing damage to and abandonment of the line. The pipeline owner alleges it has suffered approximately C$85 million in damages in connection with the abandonment and replacement of the pipeline. Flint was the construction contractor on the pipeline project. Other defendants were responsible for engineering and design-services and for specifying and providing the actual pipe, insulation and coating materials used in the line. In January 2011, the pipeline owner served a Statement of Claim on Flint and, in September 2011, Flint filed a Statement of Defense denying that the damages to the coating system of the pipeline were caused by any negligence or breach of contract of Flint. Flint believes the damages were caused or contributed to by the negligence of one or more of the co-defendants and/or by the negligent operation of the pipeline owner.
	Flint intends to continue to defend this matter vigorously; however, it cannot provide assurance that it will be successful, in whole or in part, in these efforts. The potential range of loss and the resolution of this matter cannot be determined at this time primarily due to the early stage of the discovery; the substantial uncertainty regarding the actual cause of the damage to or loss of the line; the nature and amount of each individual damage claim against the various defendants; and the uncertainty concerning legal theories and factual bases that the customer may present against all or some of the defendants.
	AECOM Merger Class-action Lawsuits: In connection with the AECOM merger, beginning on July 21, 2014, multiple putative class action lawsuits were filed in the Court of Chancery of the State of Delaware by purported URS stockholders against URS Corporation: Falato v. URS Corp., et al., City of Atlanta Firefighters’ Pension Fund v. Creel, et al., Petroutson v. URS Corp., et al., Miller v. URS Corp., et al., Oklahoma Police Pension & Retirement System v. Creel, et al., Cambridge Retirement System v. Creel, et al. and Sheet Metal Workers Local No. 33 Cleveland District Pension Plan v. URS Corp., et al. The actions named as defendants URS Corporation, the members of the URS Board of Directors, AECOM Technology and its affiliates. A number of the actions also named as a defendant JANA Partners LLC. The complaints allege, among other things, that some or all members of the URS Board of Directors breached their fiduciary duties by approving the merger, and that the other defendants aided and abetted those alleged breaches. The complaints seek, among other relief, class certification, preliminary and permanent injunctive relief, and monetary damages.
	URS Corporation intends to defend these matters vigorously; however, URS Corporation cannot provide assurance that it will be successful in these efforts. The potential range of loss and the resolution of these matters cannot be determined at this time primarily due to the early stage of the proceedings; the nature and amount of each individual damage claim against the various defendants; the uncertainty concerning legal theories and factual bases that the plaintiffs may present against all or some of the defendants; and uncertainty about the plaintiffs’ claims, if any, that might survive certain key motions, as well as a number of additional factors.
	The resolution of outstanding claims and legal proceedings is subject to inherent uncertainty, and it is reasonably possible that any resolution of these claims and legal proceedings could have a material adverse effect on us, including a substantial charge to our earnings and operating results for that period; however, an estimate of all the reasonably possible losses cannot be determined at this time.
	Insurance
	Generally, our insurance program covers workers’ compensation and employer’s liability, general liability, automobile liability, professional errors and omissions liability, property, marine property and liability, aviation liability, management liability, and contractor’s pollution liability (in addition to other policies for specific projects). We have also elected to retain a portion of the losses that occur through the use of various deductibles, limits, and self-insured retentions under our insurance programs. In addition, our insurance policies contain exclusions and sublimits that insurance providers may use to deny or restrict coverage. Excess liability, contractor’s pollution liability, and professional liability insurance policies provide coverages on a “claims-made” basis, covering only claims actually made and reported during the policy period currently in effect. Thus, if we do not continue to maintain these policies, we will have no coverage for claims made after the termination date even for claims based on events that occurred during the term of coverage. While we intend to maintain these policies, we may be unable to maintain existing coverage levels.
	Guarantee Obligations and Commitments
	As of July 4, 2014, we had the following guarantee obligations and commitments:
	We have agreed to indemnify one of our joint venture partners up to $25 million for any potential losses, damages, and liabilities associated with lawsuits in relation to general and administrative services we provide to the joint venture.
	As of July 4, 2014, we had $46 million in bank guarantees outstanding under foreign credit facilities and other banking arrangements.
	We also maintain a variety of commercial commitments that are generally made to support provisions of our contracts. In addition, in the ordinary course of business, we provide letters of credit to clients and others against advance payments and to support other business arrangements. We are required to reimburse the issuers of letters of credit for any payments they make under the letters of credit.
	In the ordinary course of business, we may provide performance assurances and guarantees related to our services. For example, these guarantees may include surety bonds, arrangements among our client, a surety, and us to ensure we perform our contractual obligations pursuant to our client agreement. If our services under a guaranteed project are later determined to have resulted in a material defect or other material deficiency, then we may be responsible for monetary damages or other legal remedies. When sufficient information about claims on guaranteed projects is available and monetary damages or other costs or losses are determined to be probable, we recognize such guarantee losses.

Accounting Policies [Abstract]	'
Principles Of Consolidation And Basis Of Presentation	'
	Principles of Consolidation and Basis of Presentation
	Our condensed consolidated financial statements include the financial position, results of operations and cash flows of URS Corporation and our majority-owned subsidiaries and joint ventures that are required to be consolidated.
	Investments in unconsolidated joint ventures are accounted for using the equity method and are included as “Investments in and advances to unconsolidated joint ventures” on our Condensed Consolidated Balance Sheets. All significant intercompany transactions and accounts have been eliminated in consolidation.
Use Of Estimates	'
	Use of and Changes in Estimates
	The preparation of our unaudited condensed consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and related disclosures at the balance sheet dates, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, we review our estimates based on information that is currently available. Changes in facts and circumstances may cause us to revise our estimates.
	Our business activities involve making significant estimates and assumptions in the normal course of business relating to our contracts. We focus on evaluating the performance of contracts individually.  These estimates and assumptions can vary in the normal course of business as contracts progress, when estimated productivity assumptions change based on experience to-date and as uncertainties are resolved. We use the cumulative catch-up method applicable to construction contract accounting to account for revisions in estimates.
	There were no material changes in estimates for the three and six months ended July 4, 2014.
	During the six months ended June 28, 2013, our results of operations included the recognition of $26 million of performance-based incentive fees from our work managing chemical demilitarization programs.  These changes in estimates resulted in increases of $26 million in operating income, $16 million in net income and $0.21 in diluted earnings per common share (“diluted EPS”) for the six months ended June 28, 2013. There were no material changes in estimates for the three months ended June 28, 2013.

The Merger Agreement provides for the merger of Merger Sub with and into our company, with our company continuing as the surviving company and a direct wholly-owned subsidiary of AECOM (the bMergerb). Immediately thereafter, as part of a single integrated transaction with the Merger, pursuant to the Merger Agreement, we will merge with and into Merger Sub I, with Merger Sub I continuing as the surviving company and a direct wholly-owned subsidiary of AECOM. Subject to the terms and conditions of the Merger Agreement, holders of URS common stock will receive consideration to be determined at closing based on the average closing price of AECOM common stock during the five business days prior to the closing date. Each outstanding share of URS common stock will be exchanged for per share consideration consisting of 0.734 shares of AECOM common stock and $33.00 in cash. URS stockholders may elect to receive cash or stock consideration, subject to proration in the event of oversubscription or undersubscription for cash consideration. Completion of the Merger is subject to certain customary conditions, including approval by both the AECOM and URS stockholders, approval of the listing of the shares of AECOM common stock to be issued in the Merger on the New York Stock Exchange, receipt of required regulatory approvals and/or expiration or termination of applicable waiting periods, effectiveness of AECOMbs registration statement on Form S-4 and receipt of customary opinions related to certain tax matters from the partiesb respective counsels. On August 4, 2014, the Federal Trade Commission granted URS and AECOM early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. The financial statements included in this Quarterly Report on Form 10-Q do not reflect any adjustments or otherwise give effect to the proposed Merger.	'

We determined that no such changes occurred during the six months ended July 4, 2014.		'		'	'
Maximum loss exposure that can not be quantified	'		'		'Exposure to Loss In addition to potential losses arising out of the carrying values of the assets and liabilities of our unconsolidated joint ventures, our maximum exposure to loss also includes performance assurances and guarantees we sometimes provide to clients on behalf of joint ventures that we do not directly control. We enter into these guarantees primarily to support the contractual obligations associated with the joint venturesb projects. The potential payment amount of an outstanding performance guarantee is typically the remaining cost of work to be performed by or on behalf of third parties under engineering and construction contracts. However, the majority of the unconsolidated joint ventures in which we participate involve cost-reimbursable, level-of-effort projects that are accounted for as service-type projects, not engineering and construction projects that would follow the percentage-of-completion or completed-contract accounting method. Revenues for service-type contracts are recognized in proportion to the number of service activities performed, in proportion to the direct costs of performing the service activities, or evenly across the period of performance, depending upon the nature of the services provided. The services we provide on these cost-reimbursable contracts are management and operations services for government clients and operations and maintenance services for non-government clients. We believe that, due to the continual changes we experience in client funding and scope definitions, reliable estimates of performance guarantees cannot be calculated because they cannot be reliably predicted. In addition, we participate in joint ventures in which the level of our participation is so minimal that we do not have access to those joint venturesb estimates to complete. The joint ventures where we perform engineering and construction contracts and where we have access to the estimates to complete, which are needed to calculate the performance guarantees, are immaterial.
