	Unless the context otherwise requires:
	•	References herein to "Jacobs" are to Jacobs Engineering Group Inc. and its predecessors;
	•	References herein to the "Company", "we", "us" or "our" are to Jacobs Engineering Group Inc. and its consolidated subsidiaries; and
	•	References herein to the "Group" are to the combined economic interests and activities of the Company and the persons and entities holding noncontrolling interests in our consolidated subsidiaries.
	The accompanying consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q. Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") have been condensed or omitted. Readers of this report should also read our consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 26, 2014 ("2014 Form 10-K") as well as Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations, which is also included in our 2014 Form 10-K.
	In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of our consolidated financial statements at December 26, 2014, and for the three month periods ended December 26, 2014 and December 27, 2013.
	Our interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year.
	Please refer to Note 16 of Notes to Consolidated Financial Statements included in our 2014 Form 10-K for the definitions of certain terms used herein.
	Use of Estimates and Assumptions
	The preparation of financial statements in conformity with U.S. GAAP requires us to employ estimates and make assumptions that affect the reported amounts of certain assets and liabilities; the revenues and expenses reported for the periods covered by the accompanying consolidated financial statements; and certain amounts disclosed in these Notes to the Consolidated Financial Statements. Although such estimates and assumptions are based on management's most recent assessment of the underlying facts and circumstances utilizing the most current information available and past experience, actual results could differ significantly from those estimates and assumptions. Our estimates, judgments, and assumptions are evaluated periodically and adjusted accordingly. Please refer to Note 2 of Notes to Consolidated Financial Statements included in our 2014 Form 10-K for a discussion of the significant estimates and assumptions affecting our consolidated financial statements.
	Fair Value and Fair Value Measurements
	Certain amounts included in the accompanying consolidated financial statements are presented at "fair value". Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants as of the date fair value is determined (the "measurement date"). When determining fair value, we consider the principal or most advantageous market in which we would transact, and we consider only those assumptions we believe a typical market participant would consider when pricing an asset or liability. In measuring fair value, we use the following inputs in the order of priority indicated:
	Level 1 - Quoted prices in active markets for identical assets or liabilities.
	Level 2 - Observable inputs other than quoted prices in active markets included in Level 1, such as (i) quoted prices for similar assets or liabilities; (ii) quoted prices in markets that have insufficient volume or infrequent transactions (i.e., less active markets); and (iii) model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data for substantially the full term of the asset or liability.
	Level 3 - Unobservable inputs to the valuation methodology that are significant to the fair value measurement.
	Please refer to Note 2 of Notes to Consolidated Financial Statements included in our 2014 Form 10-K for a more complete discussion of the various items within the consolidated financial statements measured at fair value and the methods used to determine fair value.

	On December 13, 2013, the Company acquired all of the outstanding interests in Sinclair Knight Merz Management Pty Limited and Sinclair Knight Merz Holdings Limited (collectively, "SKM"), a provider of engineering, design, procurement, construction and project management services, from the SKM shareholders. The Company purchased SKM for approximately $1.2 billion in cash. SKM's results of operations have been included in the Company's consolidated results of operations since the date of acquisition. The acquisition agreement includes customary representations, warranties, and indemnities supported by an escrow account.
	During the first quarter of fiscal 2015, we completed the final purchase price allocation of SKM. The Company recorded a number of adjustments affecting, among other things, the balance sheet position of several major projects; the estimated liabilities relating to acquired professional liability exposures; and other adjustments.
	The following table presents the final purchase price allocation for SKM (in thousands):
	Assets:
	Cash and cash equivalents	$	152,051
	Receivables and other current assets	371,331
	Property and equipment, and other	71,630
	Intangible assets	202,166
	Total assets	797,178
	Liabilities:
	Current liabilities	351,351
	Deferred tax liability	72,656
	Long-term liabilities	20,416
	Total liabilities	444,423
	Net identifiable assets acquired	352,755
	Goodwill	866,919
	Net assets acquired	$	1,219,674
	The following table presents the values assigned to the acquired SKM intangible assets (in thousands):
	Customer relationships / backlog	$	193,260
	Trade name	8,906
		$	202,166
	The useful lives of the intangible assets acquired from SKM range from 3 to 12 years.
	Some of the factors contributing to the recognition of goodwill include: (i) access to a large, highly-trained and stable workforce; (ii) the opportunity to expand our client base in Australia, Asia, South America and the U.K.; (iii) the opportunity to expand our presence in multiple industries, including: mining, infrastructure, buildings, water and energy; and (iv) the opportunity to achieve operating synergies.
	During fiscal year 2014, the Company also acquired Federal Network Services LLC ("FNS", formerly a subsidiary of Verizon), Eagleton Engineering, LLC, FMHC Corporation, Stobbarts (Nuclear) Limited, Trompeter Enterprises, and MARMAC Field Services, Inc. The results of operations of these other acquisitions, individually or in the aggregate, were not material to the Company's consolidated results for fiscal 2014. During fiscal 2014, we also acquired an additional 15% interest in Jacobs, Zamel and Turbag Consulting Engineers Company ("ZATE"), a refining, chemicals, infrastructure and civil engineering company headquartered in Al Khobar, Saudi Arabia. This transaction brought the Company's ownership in ZATE to 75%.

	Billed receivables consist of amounts invoiced to clients in accordance with the terms of our client contracts and are shown net of an allowance for doubtful accounts. We anticipate that substantially all of such billed amounts will be collected over the next twelve months.
	Unbilled receivables and retentions receivable represent reimbursable costs and amounts earned and reimbursable under contracts in progress as of the respective balance sheet dates. Such amounts become billable according to the contract terms, which usually consider the passage of time, achievement of certain milestones, or completion of the project. We anticipate that substantially all of such unbilled amounts will be billed and collected over the next twelve months.
	Claims receivable are included in "Receivables" in the accompanying Consolidated Balance Sheets and represent certain costs incurred on contracts to the extent it is probable that such claims will result in additional contract revenue and the amount of such additional revenue can be reliably estimated.

Debt Disclosure [Abstract]
Long-term Debt	Long-term Debt
	Jacobs and certain of its subsidiaries have a $1.6 billion long-term unsecured, revolving credit facility (the "2014 Facility") with a syndicate of large, U.S. and international banks and financial institutions. The 2014 Facility also provides an accordion feature that allows the Company and the lenders to increase the facility amount to $2.1 billion. The 2014 Facility did not change interest rates for borrowings outstanding under the the Company's prior credit facility, but did reduce the fees on the unused portion of the facility.
	The total amount outstanding under the 2014 Facility in the form of direct borrowings at December 26, 2014 was $706.6 million. The Company has issued $2.8 million in letters of credit under the 2014 Facility leaving $890.6 million of available borrowing capacity under the 2014 Facility at December 26, 2014. In addition, the Company had $292.4 million issued under separate, committed and uncommitted letter-of-credit facilities for total issued letters of credit of $295.2 million at December 26, 2014.
	The 2014 Facility expires in February 2019 and permits the Company to borrow under two separate tranches in U.S. dollars, certain specified foreign currencies, and any other currency that may be approved in accordance with the terms of the 2014 Facility. Depending on the Company's Consolidated Leverage Ratio, borrowings under the 2014 Facility will bear interest at either a eurocurrency rate plus a margin of between 1.0% and 1.5% or a base rate plus a margin of between 0% and 0.5%. The 2014 Facility also provides for a financial letter of credit subfacility of $300.0 million, permits performance letters of credit, and provides for a $50.0 million subfacility for swingline loans. Letters of credit are subject to fees based on the Company's Consolidated Leverage Ratio at the time any such letter of credit is issued. The Company pays a facility fee of between 0.100% and 0.250% per annum depending on the Company's Consolidated Leverage Ratio. Amounts outstanding under the 2014 Facility may be prepaid at the option of the Company without premium or penalty, subject to customary breakage fees in connection with the prepayment of eurocurrency loans. The 2014 Facility contains affirmative, negative, and financial covenants customary for financings of this type including, among other things, limitations on certain other indebtedness, loans and investments, liens, mergers, asset sales and transactions with affiliates. In addition, the 2014 Facility contains customary events of default. We were in compliance with our debt covenants at December 26, 2014.

Revenue Accounting for Contracts / Accounting for Joint Ventures [Abstract]
Revenue Accounting for Contracts / Accounting for Joint Ventures	Revenue Accounting for Contracts / Accounting for Joint Ventures
	In general, we recognize revenue at the time we provide services. Depending on the commercial terms of the contract, we recognize revenues either when costs are incurred, or using the percentage-of-completion method of accounting by relating contract costs incurred to date to the total estimated costs at completion. Contract losses are provided for in their entirety in the period they become known, without regard to the percentage-of-completion. For multiple contracts with a single customer we account for each contract separately. We also recognize as revenues, costs associated with claims and unapproved change orders to the extent it is probable that such claims and change orders will result in additional contract revenue, and the amount of such additional revenue can be reliably estimated. A significant portion of the Company's revenue is earned on cost reimbursable contracts. The percentage of revenues realized by the Company by type of contract during fiscal 2014 can be found in Note 1 of Notes to Consolidated Financial Statements included in our 2014 Form 10-K.
	Certain cost-reimbursable contracts include incentive-fee arrangements. The incentive fees in such contracts can be based on a variety of factors but the most common are the achievement of target completion dates, target costs, and/or other performance criteria. Failure to meet these targets can result in unrealized incentive fees. We recognize incentive fees based on expected results using the percentage-of-completion method of accounting. As the contract progresses and more information becomes available, the estimate of the anticipated incentive fee that will be earned is revised as necessary. We bill incentive fees based on the terms and conditions of the individual contracts. In certain situations, we are allowed to bill a portion of the incentive fees over the performance period of the contract. In other situations, we are allowed to bill incentive fees only after the target criterion has been achieved. Incentive fees which have been recognized but not billed are included in Receivables in the accompanying Consolidated Balance Sheets.
	Certain cost-reimbursable contracts with government customers as well as certain commercial clients provide that contract costs are subject to audit and adjustment. In this situation, revenues are recorded at the time services are performed based upon the amounts we expect to realize upon completion of the contracts. Revenues are not recognized for non-recoverable costs. In those situations where an audit indicates that we may have billed a client for costs not allowable under the terms of the contract, we estimate the amount of such nonbillable costs and adjust our revenues accordingly.
	When we are directly responsible for subcontractor labor or third-party materials and equipment, we reflect the costs of such items in both revenues and costs. On those projects where the client elects to pay for such items directly and we have no associated responsibility for such items, these amounts are not reflected in either revenues or costs.
	The following table sets forth pass-through costs included in revenues for each of the three months ended December 26, 2014 and December 27, 2013 (in thousands):
		For the Three Months Ended
		December 26,		December 27,
		2014		2013
	Pass-through costs included in revenues	$	706,830	$	752,023
	As is common to the industry, we execute certain contracts jointly with third parties through various forms of joint ventures and consortiums. Although the joint ventures own and hold the contracts with the clients, the services required by the contracts are typically performed by us and our joint venture partners, or by other subcontractors under subcontracting agreements with the joint ventures. The assets of our joint ventures, therefore, consist almost entirely of cash and receivables (representing amounts due from clients), and the liabilities of our joint ventures consist almost entirely of amounts due to the joint venture partners (for services provided by the partners to the joint ventures under their individual subcontracts) and other subcontractors. In general, at any given time, the equity of our joint ventures represents the undistributed profits earned on contracts the joint ventures hold with clients. Very few of our joint ventures have employees. None of our joint ventures have third-party debt or credit facilities. Our joint ventures, therefore, are simply mechanisms used to deliver engineering and construction services to clients. Rarely do they, in and of themselves, present any risk of loss to us or to our partners separate from those that we would carry if we were performing the contract on our own. Under U.S. GAAP, our share of losses associated with the contracts held by the joint ventures, if and when they occur, has always been reflected in our Consolidated Financial Statements.
	Certain of our joint ventures meet the definition of a "variable interest entity" ("VIE"). As defined in U.S. GAAP, a VIE is a legal entity in which equity investors do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack any one of the following three characteristics: (i) the power, through voting rights or similar rights, to direct the activities of a legal entity that most significantly impact the entity's economic performance; (ii) the obligation to absorb the expected losses of the legal entity; or (iii) the right to receive the expected residual returns of the legal entity. Accordingly, entities issuing consolidated financial statements (i.e., a "reporting entity") shall consolidate a VIE if the reporting entity has a "controlling financial interest" in the VIE, as demonstrated by the reporting entity having both (i) the power to direct the activities of a VIE that most significantly impact the VIE's economic performance; and (ii) the right to receive benefits from the VIE that could potentially be significant to the VIE or the obligation to absorb losses of the VIE that could potentially be significant to the VIE.
	In evaluating our VIEs for possible consolidation, we perform a qualitative analysis to determine whether or not we have a "controlling financial interest" in the VIE as defined by U.S. GAAP. We consolidate only those VIEs over which we have a controlling financial interest. For the Company’s unconsolidated joint ventures, we use the equity method of accounting. The Company does not currently participate in any significant VIEs in which it has a controlling financial interest.

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. BJJV has denied liability and is vigorously defending these claims. The Company does
	not expect this matter to have a material adverse effect on its consolidated financial statements.

Basis of Presentation [Abstract]
Use of Estimates and Assumptions	Use of Estimates and Assumptions
	The preparation of financial statements in conformity with U.S. GAAP requires us to employ estimates and make assumptions that affect the reported amounts of certain assets and liabilities; the revenues and expenses reported for the periods covered by the accompanying consolidated financial statements; and certain amounts disclosed in these Notes to the Consolidated Financial Statements. Although such estimates and assumptions are based on management's most recent assessment of the underlying facts and circumstances utilizing the most current information available and past experience, actual results could differ significantly from those estimates and assumptions. Our estimates, judgments, and assumptions are evaluated periodically and adjusted accordingly. Please refer to Note 2 of Notes to Consolidated Financial Statements included in our 2014 Form 10-K for a discussion of the significant estimates and assumptions affecting our consolidated financial statements.
New 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. The Company regularly monitors ASUs as they are issued and considers their applicability to its business. All ASUs applicable to the Company are adopted by the due date and in the manner prescribed by the FASB.
Revenue Recognition, Policy	In general, we recognize revenue at the time we provide services. Depending on the commercial terms of the contract, we recognize revenues either when costs are incurred, or using the percentage-of-completion method of accounting by relating contract costs incurred to date to the total estimated costs at completion. Contract losses are provided for in their entirety in the period they become known, without regard to the percentage-of-completion. For multiple contracts with a single customer we account for each contract separately. We also recognize as revenues, costs associated with claims and unapproved change orders to the extent it is probable that such claims and change orders will result in additional contract revenue, and the amount of such additional revenue can be reliably estimated. A significant portion of the Company's revenue is earned on cost reimbursable contracts. The percentage of revenues realized by the Company by type of contract during fiscal 2014 can be found in Note 1 of Notes to Consolidated Financial Statements included in our 2014 Form 10-K.
	Certain cost-reimbursable contracts include incentive-fee arrangements. The incentive fees in such contracts can be based on a variety of factors but the most common are the achievement of target completion dates, target costs, and/or other performance criteria. Failure to meet these targets can result in unrealized incentive fees. We recognize incentive fees based on expected results using the percentage-of-completion method of accounting. As the contract progresses and more information becomes available, the estimate of the anticipated incentive fee that will be earned is revised as necessary. We bill incentive fees based on the terms and conditions of the individual contracts. In certain situations, we are allowed to bill a portion of the incentive fees over the performance period of the contract. In other situations, we are allowed to bill incentive fees only after the target criterion has been achieved. Incentive fees which have been recognized but not billed are included in Receivables in the accompanying Consolidated Balance Sheets.
	Certain cost-reimbursable contracts with government customers as well as certain commercial clients provide that contract costs are subject to audit and adjustment. In this situation, revenues are recorded at the time services are performed based upon the amounts we expect to realize upon completion of the contracts. Revenues are not recognized for non-recoverable costs. In those situations where an audit indicates that we may have billed a client for costs not allowable under the terms of the contract, we estimate the amount of such nonbillable costs and adjust our revenues accordingly.
	When we are directly responsible for subcontractor labor or third-party materials and equipment, we reflect the costs of such items in both revenues and costs. On those projects where the client elects to pay for such items directly and we have no associated responsibility for such items, these amounts are not reflected in either revenues or costs.
Consolidation, Variable Interest Entity, Policy	As is common to the industry, we execute certain contracts jointly with third parties through various forms of joint ventures and consortiums. Although the joint ventures own and hold the contracts with the clients, the services required by the contracts are typically performed by us and our joint venture partners, or by other subcontractors under subcontracting agreements with the joint ventures. The assets of our joint ventures, therefore, consist almost entirely of cash and receivables (representing amounts due from clients), and the liabilities of our joint ventures consist almost entirely of amounts due to the joint venture partners (for services provided by the partners to the joint ventures under their individual subcontracts) and other subcontractors. In general, at any given time, the equity of our joint ventures represents the undistributed profits earned on contracts the joint ventures hold with clients. Very few of our joint ventures have employees. None of our joint ventures have third-party debt or credit facilities. Our joint ventures, therefore, are simply mechanisms used to deliver engineering and construction services to clients. Rarely do they, in and of themselves, present any risk of loss to us or to our partners separate from those that we would carry if we were performing the contract on our own. Under U.S. GAAP, our share of losses associated with the contracts held by the joint ventures, if and when they occur, has always been reflected in our Consolidated Financial Statements.
	Certain of our joint ventures meet the definition of a "variable interest entity" ("VIE"). As defined in U.S. GAAP, a VIE is a legal entity in which equity investors do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack any one of the following three characteristics: (i) the power, through voting rights or similar rights, to direct the activities of a legal entity that most significantly impact the entity's economic performance; (ii) the obligation to absorb the expected losses of the legal entity; or (iii) the right to receive the expected residual returns of the legal entity. Accordingly, entities issuing consolidated financial statements (i.e., a "reporting entity") shall consolidate a VIE if the reporting entity has a "controlling financial interest" in the VIE, as demonstrated by the reporting entity having both (i) the power to direct the activities of a VIE that most significantly impact the VIE's economic performance; and (ii) the right to receive benefits from the VIE that could potentially be significant to the VIE or the obligation to absorb losses of the VIE that could potentially be significant to the VIE.
	In evaluating our VIEs for possible consolidation, we perform a qualitative analysis to determine whether or not we have a "controlling financial interest" in the VIE as defined by U.S. GAAP. We consolidate only those VIEs over which we have a controlling financial interest. For the Company’s unconsolidated joint ventures, we use the equity method of accounting. The Company does not currently participate in any significant VIEs in which it has a controlling financial interest.
