Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	MYR Group Inc. (the “Company”) is a holding company with subsidiaries that are specialty electrical construction service providers. Its wholly-owned subsidiaries include: The L. E. Myers Co., a Delaware corporation; Harlan Electric Company, a Michigan corporation; Great Southwestern Construction, Inc., a Colorado corporation; Sturgeon Electric Company, Inc., a Michigan corporation; MYR Transmission Services, Inc., a Delaware corporation; E.S. Boulos Company, a Delaware corporation; High Country Line Construction, Inc., a Nevada corporation; Sturgeon Electric California, LLC, a Delaware limited liability company; GSW Integrated Services, LLC, a Delaware limited liability company; MYR Transmission Services Canada, Ltd., a British Columbia corporation; Northern Transmission Services, Ltd., a British Columbia corporation; and Western Pacific Enterprises Ltd., a British Columbia corporation. The Company reports its results under two business segments: Transmission and Distribution (“T&D”), and Commercial and Industrial (“C&I”). T&D customers include investor-owned utilities, cooperatives, private developers, government-funded utilities, independent power producers, independent transmission companies, industrial facility owners and other contractors. T&D provides a broad range of services, which include design, engineering, procurement, construction, upgrade, maintenance and repair services, with a particular focus on construction, maintenance and repair. C&I provides services to general contractors, commercial and industrial facility owners, local governments and developers in the western and northeastern United States and western Canada. Basis of Presentation The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial reporting and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with U.S. GAAP, have been condensed or omitted pursuant to the rules and regulations of the SEC. The Company believes that the disclosures made are adequate to make the information presented not misleading. In the opinion of management all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations, comprehensive income and cash flows with respect to the interim consolidated financial statements have been included. The consolidated balance sheet as of December 31, 2016 has been derived from the audited financial statements as of that date. The results of operations and comprehensive income are not necessarily indicative of the results for the full year or the results for any future periods. These financial statements should be read in conjunction with the audited financial statements and related notes for the year ended December 31, 2016, included in the Company’s annual report on Form 10-K, which was filed with the SEC on March 9, 2017. The Company adjusted its presentation of accrued self insurance liabilities and the related receivables for insurance claims in excess of deductibles to classify claim amounts estimated to be settled more than one year from the balance sheet date as non-current liabilities and non-current receivables. As a result of this adjustment, $ 32.9 32.1 14.6 14.7 The functional currency for the Company’s Canadian operations is the Canadian dollar. Assets and liabilities denominated in Canadian dollars are translated into U.S. dollars at the end-of-period exchange rate. Revenues and expenses are translated using average exchange rates for the periods reported. Cumulative translation adjustments are included as a separate component of accumulated other comprehensive income in shareholders’ equity. Foreign currency transaction gains and losses, arising primarily from changes in exchange rates on short term monetary assets and liabilities, are recorded in the “other income, net” line on the consolidated statements of operations. For the six months ended June 30, 2017, the Company recorded $ 0.1 0.2 The Company does not charge interest to its customers and carries its customer receivables at their face amounts, less an allowance for doubtful accounts. Included in accounts receivable are balances billed to customers pursuant to retainage provisions in certain contracts that are due upon completion of the contract and acceptance by the customer, or earlier as provided by the contract. Based on the Company’s experience in recent years, the majority of customer balances at each balance sheet date are collected within twelve months. As is common practice in the industry, the Company classifies all accounts receivable, including retainage, as current assets. The contracting cycle for certain long-term contracts may extend beyond one year, and accordingly, collection of retainage on those contracts may extend beyond one year. The Company expects a majority of the retainage recorded at June 30, 2017 to be collected within one year. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the period reported. Actual results could differ from those estimates. The most significant estimates are related to estimates of costs to complete on contracts, pending change orders and claims, shared savings, insurance reserves, income tax reserves, estimates surrounding stock-based compensation, the recoverability of goodwill and intangibles and accounts receivable reserves. In the first six months ended June 30, 2017, the Company had recognized revenues of $ 5.2 The percentage of completion method of accounting requires the Company to make estimates about the expected revenue and gross profit on each of its contracts in process. The estimates are reviewed and revised quarterly, as needed. During the three and six months ended June 30, 2017, changes in estimates pertaining to certain projects resulted in decreased consolidated gross margin of 2.1% and 1.0 During the three months ended June 30, 2016, changes in estimates pertaining to certain projects resulted in increased consolidated gross margin of 0.1 0.2 0.1 0.01 Changes to U.S. GAAP are typically established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). The Company considers the applicability and impact of all ASUs. The Company, based on its assessment, determined that any recently issued or proposed ASUs not listed below are either not applicable to the Company or adoption will have minimal impact on our consolidated financial statements. Recently Adopted Accounting Pronouncements In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718) · Excess tax benefits of $ 0.2 1.0 · The adoption of this ASU eliminated the additional paid-in capital pool (“APIC Pool”) resulting in the excess tax benefits and deficiencies to be excluded from assumed future proceeds in the calculation of diluted shares, which caused an immaterial increase in diluted weighted average shares outstanding for the three and six months ended June 30, 2017. The Company typically experiences the largest volume of restricted stock vesting in the first quarter of its fiscal year. The extent of excess tax benefits/deficiencies is subject to variation in the Company’s stock price and the timing/extent of restricted stock, performance share and phantom stock vesting and stock option exercises. · The Company elected to discontinue estimating forfeitures and will account for forfeitures as they occur. The net cumulative effect of this change was recognized as a $ 0.2 Recently Issued Accounting Pronouncements In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payments In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) The Company plans to adopt the amendments under this ASU using the modified retrospective transition approach on January 1, 2018. Under the modified retrospective transition approach, the Company will recognize any changes from the beginning of the year of initial application through retained earnings with no restatement of comparative periods. As the amendments under this ASU will supersede substantially all existing revenue guidance affecting the Company under U.S. GAAP, it will impact revenue and cost recognition on certain contracts across both the T&D and C&I business segments, in addition to impacting the Company’s business processes and information technology systems. As a result, the Company’s evaluation of the impact of this ASU and related amendments on the Company’s policies and procedures pertaining to recognition of revenue from contracts with customers, and the impact on the Company’s financial statements is ongoing. Presented below is the status of the process the Company is utilizing for the adoption of this ASU and the significant implementation matters yet to be addressed: · Established a cross-functional implementation team to assess the potential impacts of this standard. · Continue to monitor activity related to the new standard and are working with various non-authoritative groups regarding industry clarifications and interpretations, which may impact the Company’s considerations and conclusions. · Determined key factors from the five step process to recognize revenue as prescribed by the new standard that may be applicable to each of the business units that roll up into T&D and C&I business segments. · Identified significant customers and contracts and expect to have substantially completed the review of these contracts by the filing date of our third quarter 2017 Form 10-Q with any remaining contracts to be reviewed by the end of 2017. ⋅ Evaluation of the provisions and performance obligations of these contracts, and the comparison of historical accounting policies and practices to the requirements of the new standard (including the potential impact of related qualitative disclosures the Company expects to apply and a comparison to current revenue recognition policies), is in process. The Company expects to complete this process by the end of 2017. · Some of the significant items that the Company is still analyzing relate to the effects of uninstalled materials, cancelation of convenience clauses in certain master service agreements as well as variances between our backlog and unsatisfied performance obligations. The Company expects to complete the analysis of these items by the end of 2017. · Implementation of any required changes to systems and processes, including updating internal controls, is expected to be completed by the end of 2017. Based on the Company’s progress in reviewing various types of revenue arrangements, the Company expects to recognize revenue and earnings over time utilizing the cost-to-cost measure of progress for its fixed price contracts and certain master service and other service agreements, consistent with current practice. For these contracts, the cost-to-cost measure of progress best depicts the transfer of control of goods or services to the customer under the new standard.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	3. Fair Value Measurements The Company uses the three-tier hierarchy of fair value measurement, which prioritizes the inputs used in measuring fair value based upon their degree of availability in external active markets. These tiers include: Level 1 (the highest priority), defined as observable inputs, such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3 (the lowest priority), defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. As of June 30, 2017 and December 31, 2016, the Company determined that the carrying value of cash and cash equivalents approximated fair value based on Level 1 inputs. As of June 30, 2017 and December 31, 2016, the fair value of the Company’s long-term debt and capital lease obligations were based on Level 2 inputs. The Company’s long-term debt was based on variable and fixed interest rates at June 30, 2017 and December 31, 2016, for new issues with similar remaining maturities and approximated carrying value. In addition, based on borrowing rates currently available to the Company for borrowings with similar terms, the carrying values of the Company's capital lease obligations also approximated fair value.

Commitments Contingencies and Guarantees [Text Block]	8. Commitments and Contingencies Purchase Commitments As of June 30, 2017, the Company had approximately $ 2.2 Insurance and Claims Accruals The Company carries insurance policies, which are subject to certain deductibles, for workers’ compensation, general liability, automobile liability and other coverages. The deductible per occurrence for each line of coverage is up to $ 1.0 0.2 The insurance and claims accruals are based on known facts, actuarial estimates and historical trends. While recorded accruals are based on the ultimate liability, which includes amounts in excess of the deductible, a corresponding receivable for amounts in excess of the deductible is included in current assets in the consolidated balance sheets. Performance and Payment Bonds and Parent Guarantees In certain circumstances, the Company is required to provide performance and payment bonds in connection with its future performance on certain contractual commitments. The Company has indemnified its sureties for any expenses paid out under these bonds. As of June 30, 2017, an aggregate of approximately $ 515.4 29.6 From time to time the Company guarantees the obligations of wholly owned subsidiaries, including obligations under certain contracts with customers, certain lease agreements, and, in some states, obligations in connection with obtaining contractors’ licenses. Additionally, from time to time the Company is required to post letters of credit to guarantee the obligations of wholly owned subsidiaries, which reduces the borrowing availability under our Facility. Indemnities From time to time, pursuant to its service arrangements, the Company indemnifies its customers for claims related to the services it provides under those service arrangements. These indemnification obligations may subject the Company to indemnity claims and liabilities and related litigation. The Company is not aware of any material unrecorded liabilities for asserted claims in connection with these indemnification obligations. Collective Bargaining Agreements Many of the Company’s subsidiaries’ craft labor employees are covered by collective bargaining agreements. The agreements require the subsidiaries to pay specified wages, provide certain benefits and contribute certain amounts to multi-employer pension plans. If a subsidiary withdraws from any of the multi-employer pension plans or if the plans were to otherwise become underfunded, the subsidiary could incur liabilities for additional contributions related to these plans. Although the Company has been informed that the underfunding of some of the multi-employer pension plans to which its subsidiaries contribute have been classified as “critical” status, the Company is not currently aware of any potential liabilities related to this issue. Litigation and Other Legal Matters The Company is from time-to-time party to various lawsuits, claims, and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contract, property damages, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. The Company is routinely subject to other civil claims, litigation and arbitration, and regulatory investigations arising in the ordinary course of our business as well as in respect of our divested businesses. These claims, lawsuits and other proceedings include claims related to the Company’s current services and operations, as well as our historic operations. With respect to all such lawsuits, claims and proceedings, the Company records reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company does not believe that any of these proceedings, separately or in the aggregate, would be expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	10. Segment Information MYR Group is a holding company with subsidiaries that are specialty electrical contractors that serve the United States and Canadian electrical infrastructure markets. The Company has two reporting segments, each a separate operating segment, which are referred to as T&D and C&I. Performance measurement and resource allocation for the reporting segments are based on many factors. The primary financial measures used to evaluate the segment information are contract revenues and income from operations, excluding general corporate expenses. General corporate expenses include corporate facility and staffing costs, safety costs, professional fees and management fees. The accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Transmission and Distribution: The T&D segment provides a broad range of services on electric transmission and distribution networks and substation facilities which include design, engineering, procurement, construction, upgrade, maintenance and repair services with a particular focus on construction, maintenance and repair. T&D services include the construction and maintenance of high voltage transmission lines, substations and lower voltage underground and overhead distribution systems. The T&D segment also provides emergency restoration services in response to hurricane, ice or other storm-related damage. T&D customers include investor-owned utilities, cooperatives, private developers, government-funded utilities, independent power producers, independent transmission companies, industrial facility owners and other contractors. Commercial and Industrial: The C&I segment provides services such as the design, installation, maintenance and repair of commercial and industrial wiring, installation of traffic networks and the installation of bridge, roadway and tunnel lighting. Typical C&I contracts cover electrical contracting services for airports, hospitals, data centers, hotels, stadiums, convention centers, manufacturing plants, processing facilities, waste-water treatment facilities, mining facilities and transportation control and management systems. C&I segment services are generally performed in the western and northeastern United States and in western Canada. In our C&I segment, we generally provide our electric construction and maintenance services as a subcontractor to general contractors in the C&I industry, but also contract directly with facility owners. We have a diverse customer base with many long-standing relationships.

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	11. Earnings Per Share The Company computes earnings per share using the treasury stock method. Under the treasury stock method, basic earnings per share are computed by dividing net income available to shareholders by the weighted average number of common shares outstanding during the period, and diluted earnings per share are computed by dividing net income available to shareholders by the weighted average number of common shares outstanding during the period plus all potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be anti-dilutive.

All of the Company’s non-participating unvested restricted shares were included in the computation of weighted average dilutive securities.

C&I provides services to general contractors, commercial and industrial facility owners, local governments and developers in the western and northeastern United States and western Canada.
Consolidation, Policy [Policy Text Block]	Interim Consolidated Financial Information The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial reporting and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with U.S. GAAP, have been condensed or omitted pursuant to the rules and regulations of the SEC. The Company believes that the disclosures made are adequate to make the information presented not misleading. In the opinion of management all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations, comprehensive income and cash flows with respect to the interim consolidated financial statements have been included. The consolidated balance sheet as of December 31, 2016 has been derived from the audited financial statements as of that date. The results of operations and comprehensive income are not necessarily indicative of the results for the full year or the results for any future periods. These financial statements should be read in conjunction with the audited financial statements and related notes for the year ended December 31, 2016, included in the Company’s annual report on Form 10-K, which was filed with the SEC on March 9, 2017. The Company adjusted its presentation of accrued self insurance liabilities and the related receivables for insurance claims in excess of deductibles to classify claim amounts estimated to be settled more than one year from the balance sheet date as non-current liabilities and non-current receivables. As a result of this adjustment, $ 32.9 32.1 14.6 14.7
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency The functional currency for the Company’s Canadian operations is the Canadian dollar. Assets and liabilities denominated in Canadian dollars are translated into U.S. dollars at the end-of-period exchange rate. Revenues and expenses are translated using average exchange rates for the periods reported. Cumulative translation adjustments are included as a separate component of accumulated other comprehensive income in shareholders’ equity. Foreign currency transaction gains and losses, arising primarily from changes in exchange rates on short term monetary assets and liabilities, are recorded in the “other income, net” line on the consolidated statements of operations. For the six months ended June 30, 2017, the Company recorded $ 0.1 0.2
Trade and Other Accounts Receivable, Policy [Policy Text Block]	Accounts Receivable The Company does not charge interest to its customers and carries its customer receivables at their face amounts, less an allowance for doubtful accounts. Included in accounts receivable are balances billed to customers pursuant to retainage provisions in certain contracts that are due upon completion of the contract and acceptance by the customer, or earlier as provided by the contract. Based on the Company’s experience in recent years, the majority of customer balances at each balance sheet date are collected within twelve months. As is common practice in the industry, the Company classifies all accounts receivable, including retainage, as current assets. The contracting cycle for certain long-term contracts may extend beyond one year, and accordingly, collection of retainage on those contracts may extend beyond one year. The Company expects a majority of the retainage recorded at June 30, 2017 to be collected within one year.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the period reported. Actual results could differ from those estimates. The most significant estimates are related to estimates of costs to complete on contracts, pending change orders and claims, shared savings, insurance reserves, income tax reserves, estimates surrounding stock-based compensation, the recoverability of goodwill and intangibles and accounts receivable reserves. In the first six months ended June 30, 2017, the Company had recognized revenues of $ 5.2 The percentage of completion method of accounting requires the Company to make estimates about the expected revenue and gross profit on each of its contracts in process. The estimates are reviewed and revised quarterly, as needed. During the three and six months ended June 30, 2017, changes in estimates pertaining to certain projects resulted in decreased consolidated gross margin of 2.1% and 1.0 During the three months ended June 30, 2016, changes in estimates pertaining to certain projects resulted in increased consolidated gross margin of 0.1 0.2 0.1 0.01
New Accounting Pronouncements, Policy [Policy Text Block]	Changes to U.S. GAAP are typically established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). The Company considers the applicability and impact of all ASUs. The Company, based on its assessment, determined that any recently issued or proposed ASUs not listed below are either not applicable to the Company or adoption will have minimal impact on our consolidated financial statements. Recently Adopted Accounting Pronouncements In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718) · Excess tax benefits of $ 0.2 1.0 · The adoption of this ASU eliminated the additional paid-in capital pool (“APIC Pool”) resulting in the excess tax benefits and deficiencies to be excluded from assumed future proceeds in the calculation of diluted shares, which caused an immaterial increase in diluted weighted average shares outstanding for the three and six months ended June 30, 2017. The Company typically experiences the largest volume of restricted stock vesting in the first quarter of its fiscal year. The extent of excess tax benefits/deficiencies is subject to variation in the Company’s stock price and the timing/extent of restricted stock, performance share and phantom stock vesting and stock option exercises. · The Company elected to discontinue estimating forfeitures and will account for forfeitures as they occur. The net cumulative effect of this change was recognized as a $ 0.2 Recently Issued Accounting Pronouncements In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payments In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) The Company plans to adopt the amendments under this ASU using the modified retrospective transition approach on January 1, 2018. Under the modified retrospective transition approach, the Company will recognize any changes from the beginning of the year of initial application through retained earnings with no restatement of comparative periods. As the amendments under this ASU will supersede substantially all existing revenue guidance affecting the Company under U.S. GAAP, it will impact revenue and cost recognition on certain contracts across both the T&D and C&I business segments, in addition to impacting the Company’s business processes and information technology systems. As a result, the Company’s evaluation of the impact of this ASU and related amendments on the Company’s policies and procedures pertaining to recognition of revenue from contracts with customers, and the impact on the Company’s financial statements is ongoing. Presented below is the status of the process the Company is utilizing for the adoption of this ASU and the significant implementation matters yet to be addressed: · Established a cross-functional implementation team to assess the potential impacts of this standard. · Continue to monitor activity related to the new standard and are working with various non-authoritative groups regarding industry clarifications and interpretations, which may impact the Company’s considerations and conclusions. · Determined key factors from the five step process to recognize revenue as prescribed by the new standard that may be applicable to each of the business units that roll up into T&D and C&I business segments. · Identified significant customers and contracts and expect to have substantially completed the review of these contracts by the filing date of our third quarter 2017 Form 10-Q with any remaining contracts to be reviewed by the end of 2017. ⋅ Evaluation of the provisions and performance obligations of these contracts, and the comparison of historical accounting policies and practices to the requirements of the new standard (including the potential impact of related qualitative disclosures the Company expects to apply and a comparison to current revenue recognition policies), is in process. The Company expects to complete this process by the end of 2017. · Some of the significant items that the Company is still analyzing relate to the effects of uninstalled materials, cancelation of convenience clauses in certain master service agreements as well as variances between our backlog and unsatisfied performance obligations. The Company expects to complete the analysis of these items by the end of 2017. · Implementation of any required changes to systems and processes, including updating internal controls, is expected to be completed by the end of 2017. Based on the Company’s progress in reviewing various types of revenue arrangements, the Company expects to recognize revenue and earnings over time utilizing the cost-to-cost measure of progress for its fixed price contracts and certain master service and other service agreements, consistent with current practice. For these contracts, the cost-to-cost measure of progress best depicts the transfer of control of goods or services to the customer under the new standard.
