Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation and Accounting Policies The condensed consolidated financial statements include the accounts of Matrix Service Company (“Matrix”, “we”, “our”, “us”, “its” or the “Company”) and its subsidiaries, unless otherwise indicated. Intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission and do not include all information and footnotes required by generally accepted accounting principles for complete financial statements. However, the information furnished reflects all adjustments, consisting of normal recurring adjustments and other adjustments described herein, that are, in the opinion of management, necessary for a fair statement of the results of operations, cash flows and financial position for the interim periods presented. The accompanying condensed financial statements should be read in conjunction with the audited financial statements for the year ended June 30, 2015 , included in the Company’s Annual Report on Form 10-K for the year then ended. Recently Issued Accounting Standards Accounting Standards Update 2015-17 (Topic 740), Balance Sheet Classification of Deferred Taxes On November 20, 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-17, which will require entities to present deferred tax assets ("DTAs") and deferred tax liabilities ("DTLs") as noncurrent in a classified balance sheet. The ASU simplifies the current guidance, which requires entities to separately present DTAs and DTLs as current and noncurrent in a classified balance sheet based on the classification of the related asset or liability. For public business entities, the ASU will be effective for annual periods beginning after December 15, 2016, and interim periods within those years with early adoption permitted. The Company has elected to retrospectively early adopt ASU 2015-17, effective for the quarter ended December 31, 2015. The quantitative effects of the change on the prior balance sheet presented, for the fiscal year ended June 30, 2015, resulted in a net reclassification of $6.6 million and $6.6 million from the "Deferred income taxes" current asset and liability financial statement line items, respectively, to the "Deferred income taxes" asset and liability financial statement line items included in the noncurrent asset and liability sections of the balance sheet. Accounting Standards Update 2014-09 (Topic 606), Revenue from Contracts with Customers On May 28, 2014, the FASB issued ASU No. 2014-09. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of 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.” The ASU also requires entities to disclose both quantitative and qualitative information that enables users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The ASU’s disclosure requirements are significantly more comprehensive than those in existing revenue standards. The ASU applies to all contracts with customers except those that are within the scope of other topics in the FASB Accounting Standards Codification ("ASC"). In July 2015, the FASB deferred the effective date of ASU 2014-09 by one year. With the deferral, this ASU is now effective for annual reporting periods beginning after December 15, 2017, with early adoption now permitted on a limited basis. Upon adoption, the Company may elect one of two application methods, a full retrospective application or a modified retrospective application. We expect to adopt this standard on July 1, 2018 and are currently evaluating its expected impact on our financial statements. Accounting Standards Update 2014-15 (Subtopic 205-40)—Presentation of Financial Statements—Going Concern : Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern On August 27, 2014, the FASB issued ASU 2014-15, which provides guidance on determining when and how reporting entities must disclose going-concern uncertainties in their financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date of issuance of the entity’s financial statements. Further, an entity must provide certain disclosures if there is “substantial doubt about the entity’s ability to continue as a going concern.” The FASB believes that requiring management to perform the assessment will enhance the timeliness, clarity, and consistency of related disclosures and improve convergence with international financial reporting standards ("IFRSs") (which emphasize management’s responsibility for performing the going-concern assessment). However, the time horizon for the assessment (look-forward period) and the disclosure thresholds under U.S. GAAP and IFRSs will continue to differ. The ASU is effective for annual periods ending after December 15, 2016, and interim periods thereafter; early adoption is permitted. We expect to adopt this standard on July 1, 2016. Accounting Standards Update 2015-16—Business Combinations (Topic 805)—Simplifying the Accounting for Measurement-Period Adjustments On September 25, 2015, the FASB issued ASU 2015-16 to simplify the accounting for measurement-period adjustments. The ASU was issued in response to stakeholder feedback that restatements of prior periods to reflect adjustments made to provisional amounts recognized in a business combination increase the cost and complexity of financial reporting but do not significantly improve the usefulness of the information. Under the ASU, an acquirer must recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The ASU also requires acquirers to present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. For public business entities, the ASU is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. We expect to adopt this standard on July 1, 2016.

Uncompleted Contracts	Uncompleted Contracts Contract terms of the Company’s construction contracts generally provide for progress billings based on project milestones. The excess of costs incurred and estimated earnings over amounts billed on uncompleted contracts is reported as a current asset. The excess of amounts billed over costs incurred and estimated earnings recognized on uncompleted contracts is reported as a current liability. Gross and net amounts on uncompleted contracts are as follows: December 31, June 30, (in thousands) Costs incurred and estimated earnings recognized on uncompleted contracts $ 1,937,286 $ 1,633,780 Billings on uncompleted contracts 1,969,683 1,644,413 $ (32,397 ) $ (10,633 ) Shown in balance sheet as: Costs and estimated earnings in excess of billings on uncompleted contracts $ 81,743 $ 86,071 Billings on uncompleted contracts in excess of costs and estimated earnings 114,140 96,704 $ (32,397 ) $ (10,633 ) Progress billings in accounts receivable at December 31, 2015 and June 30, 2015 included retentions to be collected within one year of $25.3 million and $25.2 million , respectively. Contract retentions collectible beyond one year are included in Other Assets in the Condensed Consolidated Balance Sheet and totaled $5.6 million at December 31, 2015 and $2.8 million at June 30, 2015 . Other In the three and six months ended December 31, 2014 our results of operations were materially impacted by charges resulting from a change in estimate related to an acquired EPC joint venture project in the Electrical Infrastructure segment. The charges resulted in a reduction to operating income of $22.9 million and $26.2 million and an after-tax reduction of $7.9 million and $9.0 million to net income attributable to Matrix Service Company, respectively. The Company recorded an additional charge on this project in the second quarter of fiscal 2016. The charge resulted in a reduction of operating income in the Electrical Infrastructure segment of $5.4 million and $5.5 million and a reduction of $2.0 million in net income attributable to Matrix Service Company in the three and six months ended December 31, 2015, respectively. The fiscal 2016 project charge was attributable to higher than expected project closeout costs. The Company reached substantial completion on the project in the fourth quarter of fiscal 2015.

The CDOR Rate is equal to the sum of the annual rate of interest, which is the rate determined as being the arithmetic average of the quotations of all institutions listed in respect of the relevant CDOR interest period for Canadian Dollar denominated bankers’ acceptances, plus 0.1% . The Canadian Prime Rate is equal to the greater of (i) the rate of interest per annum most recently announced or established by JPMorgan Chase Bank, N.A., Toronto Branch as its reference rate in effect on such day for determining interest rates for Canadian Dollar denominated commercial loans in Canada and (ii) the CDOR Rate plus 1.0%. The Unused Credit Facility Fee is between 0.20% and 0.35% based on the Senior Leverage Ratio. The Credit Agreement includes a Senior Leverage Ratio covenant, which provides that Consolidated Funded Indebtedness, as of the end of any fiscal quarter, may not exceed 2.5 times Consolidated EBITDA, as defined in the Credit Agreement, over the previous four quarters. For the four quarters ended December 31, 2015 , Consolidated EBITDA, as defined in the Credit Agreement, was $65.4 million . Accordingly, at December 31, 2015 , there was a restriction on our ability to access the full amount of the credit facility. Consolidated Funded Indebtedness at December 31, 2015 was $22.3 million .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We use the asset and liability approach for financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances based on our judgments and estimates are established when necessary to reduce deferred tax assets to the amount expected to be realized in future operating results. Company management believes that realization of deferred tax assets in excess of the valuation allowance is more likely than not. Our estimates are based on facts and circumstances in existence as well as interpretations of existing tax regulations and laws applied to the facts and circumstances. The Company provides for income taxes regardless of whether it has received a tax assessment. Taxes are provided when it is considered probable that additional taxes will be due in excess of amounts included in the tax return. The Company regularly reviews exposure to additional income taxes due, and as further information is known or events occur, adjustments may be recorded. Our effective tax rate for the three months ended December 31, 2015 was 32.1% compared to (31.3)% in the same period a year earlier. Our effective tax rate for the six months ended December 31, 2015 was 33.8% compared to 103.8% in the same period a year earlier. Our effective tax rates for the three and six months ended December 31, 2015 and 2014, in comparison to our statutory rate, were impacted in part by the acquired EPC joint venture project charges in which the Company has a 65% interest and does not receive a tax benefit. The Company recorded a discrete benefit of $0.9 million in the three months ended December 31, 2015, primarily relating to the retroactive application of the R&D tax credit. In addition, the Company recorded discrete benefits of $ 1.4 million in the six months ended December 31, 2015 primarily relating to the retroactive application of the R&D tax credit and a foreign currency item. As stated in Note 1, the Company has elected to retrospectively early adopt ASU 2015-17, effective for the quarter ended December 31, 2015. The quantitative effects of the change on the prior balance sheet presented, for the fiscal year ended June 30, 2015, resulted in a reclassification of $6.6 million and $6.6 million from the "Deferred income taxes" current asset and liability financial statement line items, respectively, to the "Deferred income taxes" asset and liability financial statement line items included in the noncurrent asset and liability sections of the balance sheet.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Insurance Reserves The Company maintains insurance coverage for various aspects of its operations. However, exposure to potential losses is retained through the use of deductibles, self-insured retentions and coverage limits. Typically our contracts require us to indemnify our customers for injury, damage or loss arising from the performance of our services and provide warranties for materials and workmanship. The Company may also be required to name the customer as an additional insured up to the limits of insurance available, or we may be required to purchase special insurance policies or surety bonds for specific customers or provide letters of credit in lieu of bonds to satisfy performance and financial guarantees on some projects. Matrix maintains a performance and payment bonding line sufficient to support the business. The Company generally requires its subcontractors to indemnify the Company and the Company’s customer and name the Company as an additional insured for activities arising out of the subcontractors’ work. We also require certain subcontractors to provide additional insurance policies, including surety bonds in favor of the Company, to secure the subcontractors’ work or as required by the subcontract. There can be no assurance that our insurance and the additional insurance coverage provided by our subcontractors will fully protect us against a valid claim or loss under the contracts with our customers. Unapproved Change Orders and Claims Costs and estimated earnings in excess of billings on uncompleted contracts included revenues for unapproved change orders and claims of $11.3 million at December 31, 2015 and $12.7 million at June 30, 2015 . Generally, collection of amounts related to unapproved change orders and claims is expected within twelve months. However, since customers may not pay these amounts until final resolution of related claims, collection of these amounts may extend beyond one year. Other The Company and its subsidiaries are participants in various legal actions. It is the opinion of management that none of the known legal actions will have a material impact on the Company’s financial position, results of operations or liquidity.
