Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies Overview The Goldfield Corporation (the “Company”) was incorporated in Wyoming in 1906 and subsequently reincorporated in Delaware in 1968. The Company’s principal line of business is electrical construction. The principal market for the Company’s electrical construction operation is electric utilities throughout much of the United States. Basis of Financial Statement Presentation In the opinion of management, the accompanying unaudited interim consolidated financial statements include all adjustments necessary to present fairly the Company’s financial position, results of operations, and changes in cash flows for the interim periods reported. These adjustments are of a normal recurring nature. All financial statements presented herein are unaudited with the exception of the consolidated balance sheet as of December 31, 2014 , which was derived from the audited consolidated financial statements. The results of operations for the interim periods shown in this report are not necessarily indicative of results to be expected for the fiscal year. These statements should be read in conjunction with the financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2014 . Allowance for Doubtful Accounts The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on customer specific information and historical write-off experience. The Company reviews its allowance for doubtful accounts quarterly. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Any increase in the allowance account has a corresponding negative effect on the results of operations. As of both June 30, 2015 and December 31, 2014 , upon its review, management determined it was not necessary to record an allowance for doubtful accounts due to the majority of accounts receivable being generated by electrical utility customers who the Company considers creditworthy based on timely collection history and other considerations. Use of Estimates Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these financial statements in conformity with U. S. generally accepted accounting principles (“GAAP”). Actual results could differ from those estimates. Management considers the most significant estimates in preparing these financial statements to be the estimated cost to complete electrical construction contracts in progress, the adequacy of the accrued remediation costs and the realizability of deferred tax assets. Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, accounts receivable and accrued billings, notes receivable, restricted cash collateral deposited with insurance carriers, cash surrender value of life insurance policies, accounts payable, notes payable, and other current liabilities. Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value guidance establishes a valuation hierarchy, which requires maximizing the use of observable inputs when measuring fair value. The three levels of inputs that may be used are: Level 1 - Quoted market prices in active markets for identical assets or liabilities. Level 2 - Observable market based inputs or other observable inputs. Level 3 - Significant unobservable inputs that cannot be corroborated by observable market data. These values are generally determined using valuation models incorporating management’s estimates of market participant assumptions. Fair values of financial instruments are estimated through the use of public market prices, quotes from financial institutions, and other available information. Management considers the carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable and accrued billings, accounts payable and accrued liabilities, to approximate fair value due to the immediate or short-term maturity of these financial instruments. The fair value of notes receivable is considered by management to approximate carrying value based on their interest rates and terms, maturities, collateral, and current status of the receivables. The fair value of the Company’s long-term notes payable are also estimated by management to approximate their carrying value since the interest rates prescribed by Branch Banking and Trust Company (the “Bank”) are variable market interest rates and are adjusted periodically. Restricted cash is considered by management to approximate fair value due to the nature of the asset held in a secured interest bearing bank account. The carrying value of cash surrender value of life insurance is also considered by management to approximate fair value as the carrying value is based on the current settlement value under the contract, as provided by the carrier. Restricted Cash The Company’s restricted cash includes cash deposited in a secured interest bearing bank account, as required by the Collateral Trust Agreement in connection with the Company’s workers’ compensation insurance policies, as described in note 8. Goodwill and Intangible Assets Intangible assets with finite useful lives are recorded at cost upon acquisition, and amortized over the term of the related contract or useful life, as applicable. Intangible assets held by the Company with finite useful lives include customer relationships and trademarks. All definite lived intangibles are amortized over their estimated useful lives. The Company reviews the values recorded for intangible assets and goodwill to assess recoverability from future operations annually or whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. As of December 31, 2014 , the Company assessed the recoverability of its long-lived assets and believed that there were no events or circumstances present that would require a test of recoverability on those assets. As a result, there was no impairment of the carrying amounts of such assets and no reduction in their estimated useful lives. Segment Reporting The Company operates as a single reportable segment, electrical construction, under ASC Topic 280-10-50 Disclosures about Segments of an Enterprise and Related Information . Certain corporate costs are not allocated to a segment. Reclassifications Certain amounts previously reflected in the prior year statement of cash flows have been reclassified to conform to the Company’s 2015 presentation. The cash flows from operating activities includes amounts under contract loss accruals which were previously reported within accounts payable and accrued liabilities. This reclassification had no effect on the previously reported total cash flows from operating activities. Recent Accounting Pronouncements In April 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) 2014-08 relating to the reporting of discontinued operations and the disclosures related to disposals of components of an entity. The new standard addresses the question around whether the disposal represents a strategic shift, if the operations and cash flows can be clearly distinguished and continuing involvement will no longer preclude a disposal from being presented as discontinued operations. These changes were effective for the Company for interim and annual periods after December 15, 2014 and had no material impact on its consolidated financial statements . In May 2014, the FASB issued ASU 2014-09, which will replace most existing revenue recognition guidance in U.S. generally accepted accounting principles and is intended to improve and converge the financial reporting requirements for revenue from contracts with customers with International Financial Reporting Standards (“IFRS”) . The core principle of ASU 2014-09 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014-09 allows for both retrospective and prospective methods of adoption and is effective for periods beginning after December 15, 2016. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2014-09 will have on its consolidated financial statements. In July 2015, a one-year deferral of the revenue recognition standard’s effective date was approved. Public business entities are required to apply the revenue recognition standard to annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early application is permitted but not before the original effective date for public business entities (annual reporting periods beginning after December 15, 2016). The option to use either a retrospective or cumulative-effective transition method did not change. In August 2014, the FASB issued ASU 2014-15 requiring management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. The standard also provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new guidance is effective for the annual period ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company is currently evaluating the impact that the adoption of ASU 2014-15 will have on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03 that intends to simplify the presentation of debt issuance costs. The new standard will more closely align the presentation of debt issuance costs under U.S. generally accepted accounting principles with the presentation under comparable IFRS standards. Debt issuance costs related to a recognized debt liability will be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. ASU 2015-03 is effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The cost of issuing debt will no longer be recorded as a separate asset, except when incurred before receipt of the funding from the associated debt liability. Under current U.S. generally accepted accounting principles, debt issuance costs are reported on the balance sheet as assets and amortized as interest expense. The costs will continue to be amortized to interest expense using the effective interest method. The Company is currently evaluating the impact that the adoption of ASU 2015-03 will have on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-05 which provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The guidance will not change U.S. generally accepted accounting principles for a customer ’ s accounting for service contracts. The standard will be effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years . The Company is currently evaluating the impact that the adoption of ASU 2015-05 will have on its consolidated financial statements.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The following table presents the provision for income tax and the effective tax rate from continuing operations for the three and six month periods ended June 30 as indicated: Three Months Ended Six Months Ended 2015 2014 2015 2014 Income tax provision $ 1,285,701 $ 266,443 $ 547,392 $ 464,583 Effective income tax rate 45.9 % 38.4 % 45.1 % 37.9 % The Company’s expected tax rate for the year ending December 31, 2015 , which was calculated based on the estimated annual operating results for the year, is 45.1% . The expected tax rate differs from the federal statutory rate of 34.0% mainly due to non-deductible expenses and to a lesser extent state income taxes. The effective tax rate for the three and six months ended June 30, 2015 were 45.9% and 45.1% , respectively. The effective tax rate for the three months ended June 30, 2015 differs from the expected tax rate due to an adjustment of annual operating results for the year. The effective tax rate for the six months ended June 30, 2015 reflects the expected tax rate for the year. The effective tax rate for the three and six months ended June 30, 2014 were 38.4% and 37.9% , respectively, and differ from the federal statutory rate of 34.0% primarily due to state income taxes. The current deferred tax assets decreased to $948,000 as of June 30, 2015 from $2.3 million as of December 31, 2014 primarily due to the decrease in accrued contract losses. The non-current deferred tax liabilities were $7.9 million and $8.0 million as of June 30, 2015 and December 31, 2014 , respectively. The carrying amounts of deferred tax assets are reduced by a valuation allowance if, based on the available evidence, it is more likely than not such assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which the deferred tax assets are expected to be recovered or settled. In the assessment for a valuation allowance, appropriate consideration is given to positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods, experience with loss carryforwards expiring unused, and tax planning alternatives. If the Company determines it will not be able to realize all or part of the deferred tax assets, a valuation allowance would be recorded to reduce deferred tax assets to the amount that is more likely than not to be realized. Based on assumptions with respect to forecasts of future taxable income and tax planning, among others, the Company anticipates being able to generate sufficient taxable income to utilize the deferred tax assets. Therefore, the Company has not recorded a valuation allowance against deferred tax assets. The minimum amount of future taxable income required to be generated to fully realize the deferred tax assets as of June 30, 2015 is approximately $3.0 million . The Company has gross unrecognized tax benefits of $11,000 as of both June 30, 2015 and December 31, 2014 . The Company believes that it is reasonably possible that the liability for unrecognized tax benefits related to certain state income tax matters may be settled within the next twelve months. The federal statute of limitation has expired for tax years prior to 2008 and relevant state statutes vary. The Company is currently not under any income tax audits or examinations and does not expect the assessment of any significant additional tax in excess of amounts provided. The Company accrues interest and penalties related to unrecognized tax benefits as interest expense and other general and administrative expenses, respectively, and not as a component of income taxes.

Discontinued Operations

Discontinued Operations	6 Months Ended

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations Commitments and Contingencies Related to Discontinued Operations Through certain of our subsidiaries and predecessor companies, the Company was previously engaged in mining activities and ended all such activities in December 2002. Effective September 15, 2014, the Company entered into an Administrative Order on Consent (“AOC”) with the United States Environmental Protection Agency (the “EPA”) with respect to a previously owned mining property, the Sierra Zinc Site located in Stevens County, Washington (the “Site”). The Company sold the Site over fifty years ago. The Site includes a tailings impoundment that was not previously reclaimed. Pursuant to the AOC, the Company agreed to undertake certain remediation actions at the Site, which work has commenced and is expected to be substantially completed by September 30, 2015. The contract price for this work is $1.3 million . As of June 30, 2015 , approximately 60.9% of the contract work was completed, with a remaining balance of contract work of $516,000 . This amount does not include certain other charges, such as potential change orders, environmental oversight costs and other direct and indirect costs. Based on the foregoing, the Company has reasonably estimated the amounts related to this response action in accordance with ASC Topic 450-20, Loss Contingencies, and established a contingency provision within discontinued operations. As of June 30, 2015 and December 31, 2014 , the balance of the estimated contingency provision accrued by the Company was $815,000 and $1.1 million , respectively. This contingency provision represents the estimated costs of the response action, as provided by the Company’s environmental consultants, as well as the anticipated legal costs. It is reasonably possible the total actual costs to be incurred at the Site in future periods may vary from this estimate. During the three and six months ended June 30, 2015 , the Company increased its contingency provision within discontinued operations by $356,000 . The increase for the three and six months ended June 30, 2015 is associated with amounts already expended and the estimated future costs anticipated for professional, legal and EPA costs, in excess of amounts provisioned in 2014. This increase is mainly attributable to changes in the scope of the project management portion, as required by the EPA and is estimated based on information provided by the Company’s environmental consultants. The provision will be reviewed periodically based upon facts and circumstances available at the time. The costs provisioned for future expenditures related to this environmental obligation are not discounted to present value. The Company made claims with two of its insurers for certain defense and remediation costs related to the Site. In December 2014, the Company received $377,000 from these insurers in full settlement of the previously disclosed declaratory judgment actions related to such claims. This payment was recorded upon its receipt and is recorded as a gain within discontinued operations and is not reflected in the accrued remediation costs. In addition, the Company previously received defense reimbursements from the insurers aggregating $201,000 , which is reflected in the calculation of the contingency provision. As of June 30, 2015 and December 31, 2014 , respectively, discontinued operations had no liabilities other than the accrued remediation costs associated with the aforementioned EPA action.

The effective tax benefit rate differs from the statutory rate of (34.0)% primarily due to non-deductible expenses and state income taxes. The Company’s effective tax benefit rates related to discontinued operations for both the three and six month periods ended June 30, 2014 was (37.9)% . The effective tax benefit rate differs from the statutory rate of (34.0)% primarily due to state income taxes.

(“C&C”), collectively (the “Debtors,”) were parties to a Master Loan Agreement, dated March 6, 2015 (the “2015 Master Loan Agreement”), with Branch Banking and Trust Company (the “Bank”). All loans with the Bank are guaranteed by the Debtors and include the grant of a continuing security interest in all now owned, hereafter acquired and wherever located personal property of the Debtors. As of June 30, 2015 , the Company had a loan agreement and a series of related ancillary agreements with the Bank providing for a revolving line of credit loan for a maximum principal amount of $15.0 million , to be used as a “ Working Capital Loan .” As of June 30, 2015 and December 31, 2014 , borrowings under the Working Capital Loan were $3.5 million and $0 , respectively. The Working Capital Loan will bear interest at a rate per annum equal to one month LIBOR (as defined in the ancillary loan documents) plus two percent 2.00% (previously 2.50% ), which will be adjusted monthly and subject to a maximum of 24.00% . Pricing is based on the following table: Leverage Ratio Applicable Margin for LIBOR Loans and Letter of Credit Fees Unused Commitment Fee < 1.0x 175.0 bps 25 bps “Leverage ratio” means total liabilities to tangible net worth. Pricing will be adjusted on a quarterly basis based on the table above and the Company’s quarterly financial reports with any interest rate changes taking effect in the month following receipt of the quarterly financial reports. Interest only payments are payable monthly commencing on January 16, 2014, and continuing on the same day of each month thereafter, until June 16, 2016. Under the ancillary agreements relating to the Working Capital Loan , the Company agrees to pay an unused commitment fee on any difference between the face amount of the Working Capital Loan and the amount of credit it actually uses, determined by the average of the daily amount of credit outstanding during the specified period. The fee will be calculated annually at the rates set forth in the table above and was due on April 1, 2014 and the same day of each following quarter until the maturity date of the Working Capital Loan . The unused portion of the Working Capital Loan as of June 30, 2015 , was $11.5 million . The Working Capital Loan , as described above, and the $10.0 Million Equipment Loan , bear interest at a rate per annum equal to one month LIBOR (as defined in the ancillary loan documents) plus two percent 2.00% , which is adjusted monthly and subject to a maximum interest rate of 24.00% .

The Company’s debt arrangements contain various financial and other covenants including, but not limited to: minimum tangible net worth, maximum debt to tangible net worth ratio and fixed charge coverage ratio. Other loan covenants prohibit, among other things, a change in legal form of the Company, and entering into a merger or consolidation. The loans also have cross-default provisions whereby any default under any loans of the Company (or its subsidiaries) with the Bank will constitute a default under all of the other loans of the Company (and its subsidiaries) with the Bank.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Performance Bonds In certain circumstances, the Company is required to provide performance bonds to secure its contractual commitments. Management is not aware of any performance bonds issued for the Company that have ever been called by a customer. As of June 30, 2015 , outstanding performance bonds issued on behalf of the Company’s electrical construction subsidiary amounted to approximately $59.7 million . Collective Bargaining Agreements C&C, one of the Company’s electrical construction subsidiaries, is party to collective bargaining agreements with unions representing workers performing field construction operations. The collective bargaining agreements expire at various times and have typically been renegotiated and renewed on terms similar to the ones contained in the expiring agreements. The agreements require the subsidiary to pay specified wages, provide certain benefits to their respective union employees and contribute certain amounts to multi-employer pension plans and employee benefit trusts. The subsidiary’s multi-employer pension plan contribution rates generally are specified in the collective bargaining agreements (usually on an annual basis), and contributions are made to the plans on a “pay-as-you-go” basis based on such subsidiary’s union employee payrolls, which cannot be determined for future periods because contributions depend on, among other things, the number of union employees that such subsidiary employs at any given time; the plans in which it may participate vary depending on the projects it has ongoing at any time; and the need for union resources in connection with those projects. If the subsidiary withdraws from, or otherwise terminates its participation in, one or more multi-employer pension plans, or if the plans were to otherwise become substantially underfunded, such subsidiary could be assessed liabilities for additional contributions related to the underfunding of these plans. The Company is not aware of any amounts of withdrawal liability that have been incurred as a result of a withdrawal by C&C from any multi-employer defined benefit pension plans.

Earnings Per Share [Abstract]
Income (Loss) Per Share of Common Stock	Income (Loss) Per Share of Common Stock Basic income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common stock shares outstanding during the period. Diluted income (loss) per share reflects the potential dilution that could occur if common stock equivalents, such as stock options outstanding, were exercised into common stock that subsequently shared in the earnings of the Company. As of June 30, 2015 and 2014 , the Company had no common stock equivalents. The computation of the weighted average number of common stock shares outstanding excludes 2,362,418 shares of Treasury Stock for each of the three and six month periods ended June 30, 2015 and 2014 .

The purchase price was $7.3 million in cash, subject to certain customary post-closing adjustments. As of December 31, 2014 all such adjustments were recognized. In connection with the acquisition of C&C, the Company acquired intangible assets with definite useful lives primarily consisting of trademarks and names, customer relationships and non-competition agreements and are amortized over periods from five to twenty years . The aggregate cash consideration paid, net of cash acquired of $1.4 million , was $5.8 million , of which $101,000 was allocated to goodwill, $1.0 million to acquired other intangible assets, $3.3 million to property and equipment, $2.6 million to net current assets and $1.3 million to net liabilities assumed.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview and Basis of Financial Statement Presentation	Overview The Goldfield Corporation (the “Company”) was incorporated in Wyoming in 1906 and subsequently reincorporated in Delaware in 1968. The Company’s principal line of business is electrical construction. The principal market for the Company’s electrical construction operation is electric utilities throughout much of the United States. Basis of Financial Statement Presentation In the opinion of management, the accompanying unaudited interim consolidated financial statements include all adjustments necessary to present fairly the Company’s financial position, results of operations, and changes in cash flows for the interim periods reported. These adjustments are of a normal recurring nature. All financial statements presented herein are unaudited with the exception of the consolidated balance sheet as of December 31, 2014 , which was derived from the audited consolidated financial statements. The results of operations for the interim periods shown in this report are not necessarily indicative of results to be expected for the fiscal year. These statements should be read in conjunction with the financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2014 .
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on customer specific information and historical write-off experience. The Company reviews its allowance for doubtful accounts quarterly. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Any increase in the allowance account has a corresponding negative effect on the results of operations. As of both June 30, 2015 and December 31, 2014 , upon its review, management determined it was not necessary to record an allowance for doubtful accounts due to the majority of accounts receivable being generated by electrical utility customers who the Company considers creditworthy based on timely collection history and other considerations.
Use of Estimates	Use of Estimates Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these financial statements in conformity with U. S. generally accepted accounting principles (“GAAP”). Actual results could differ from those estimates. Management considers the most significant estimates in preparing these financial statements to be the estimated cost to complete electrical construction contracts in progress, the adequacy of the accrued remediation costs and the realizability of deferred tax assets.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, accounts receivable and accrued billings, notes receivable, restricted cash collateral deposited with insurance carriers, cash surrender value of life insurance policies, accounts payable, notes payable, and other current liabilities. Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value guidance establishes a valuation hierarchy, which requires maximizing the use of observable inputs when measuring fair value. The three levels of inputs that may be used are: Level 1 - Quoted market prices in active markets for identical assets or liabilities. Level 2 - Observable market based inputs or other observable inputs. Level 3 - Significant unobservable inputs that cannot be corroborated by observable market data. These values are generally determined using valuation models incorporating management’s estimates of market participant assumptions. Fair values of financial instruments are estimated through the use of public market prices, quotes from financial institutions, and other available information. Management considers the carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable and accrued billings, accounts payable and accrued liabilities, to approximate fair value due to the immediate or short-term maturity of these financial instruments. The fair value of notes receivable is considered by management to approximate carrying value based on their interest rates and terms, maturities, collateral, and current status of the receivables. The fair value of the Company’s long-term notes payable are also estimated by management to approximate their carrying value since the interest rates prescribed by Branch Banking and Trust Company (the “Bank”) are variable market interest rates and are adjusted periodically. Restricted cash is considered by management to approximate fair value due to the nature of the asset held in a secured interest bearing bank account. The carrying value of cash surrender value of life insurance is also considered by management to approximate fair value as the carrying value is based on the current settlement value under the contract, as provided by the carrier.
Restricted Cash	Restricted Cash The Company’s restricted cash includes cash deposited in a secured interest bearing bank account, as required by the Collateral Trust Agreement in connection with the Company’s workers’ compensation insurance policies, as described in note 8.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Intangible assets with finite useful lives are recorded at cost upon acquisition, and amortized over the term of the related contract or useful life, as applicable. Intangible assets held by the Company with finite useful lives include customer relationships and trademarks. All definite lived intangibles are amortized over their estimated useful lives. The Company reviews the values recorded for intangible assets and goodwill to assess recoverability from future operations annually or whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. As of December 31, 2014 , the Company assessed the recoverability of its long-lived assets and believed that there were no events or circumstances present that would require a test of recoverability on those assets. As a result, there was no impairment of the carrying amounts of such assets and no reduction in their estimated useful lives.
Segment Reporting	Segment Reporting The Company operates as a single reportable segment, electrical construction, under ASC Topic 280-10-50 Disclosures about Segments of an Enterprise and Related Information . Certain corporate costs are not allocated to a segment.
Reclassifications	Reclassifications Certain amounts previously reflected in the prior year statement of cash flows have been reclassified to conform to the Company’s 2015 presentation. The cash flows from operating activities includes amounts under contract loss accruals which were previously reported within accounts payable and accrued liabilities. This reclassification had no effect on the previously reported total cash flows from operating activities
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) 2014-08 relating to the reporting of discontinued operations and the disclosures related to disposals of components of an entity. The new standard addresses the question around whether the disposal represents a strategic shift, if the operations and cash flows can be clearly distinguished and continuing involvement will no longer preclude a disposal from being presented as discontinued operations. These changes were effective for the Company for interim and annual periods after December 15, 2014 and had no material impact on its consolidated financial statements . In May 2014, the FASB issued ASU 2014-09, which will replace most existing revenue recognition guidance in U.S. generally accepted accounting principles and is intended to improve and converge the financial reporting requirements for revenue from contracts with customers with International Financial Reporting Standards (“IFRS”) . The core principle of ASU 2014-09 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014-09 allows for both retrospective and prospective methods of adoption and is effective for periods beginning after December 15, 2016. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2014-09 will have on its consolidated financial statements. In July 2015, a one-year deferral of the revenue recognition standard’s effective date was approved. Public business entities are required to apply the revenue recognition standard to annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early application is permitted but not before the original effective date for public business entities (annual reporting periods beginning after December 15, 2016). The option to use either a retrospective or cumulative-effective transition method did not change. In August 2014, the FASB issued ASU 2014-15 requiring management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. The standard also provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new guidance is effective for the annual period ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company is currently evaluating the impact that the adoption of ASU 2014-15 will have on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03 that intends to simplify the presentation of debt issuance costs. The new standard will more closely align the presentation of debt issuance costs under U.S. generally accepted accounting principles with the presentation under comparable IFRS standards. Debt issuance costs related to a recognized debt liability will be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. ASU 2015-03 is effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The cost of issuing debt will no longer be recorded as a separate asset, except when incurred before receipt of the funding from the associated debt liability. Under current U.S. generally accepted accounting principles, debt issuance costs are reported on the balance sheet as assets and amortized as interest expense. The costs will continue to be amortized to interest expense using the effective interest method. The Company is currently evaluating the impact that the adoption of ASU 2015-03 will have on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-05 which provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The guidance will not change U.S. generally accepted accounting principles for a customer ’ s accounting for service contracts. The standard will be effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years . The Company is currently evaluating the impact that the adoption of ASU 2015-05 will have on its consolidated financial statements.
