	us-gaap	Earnings Per Share Reconciliation Disclosure EarningsPerShareReconciliationDisclosure	Basic earnings or loss per share is computed by dividing net income or loss attributable to MasTec by the weighted average number of common shares outstanding for the period, which excludes non-participating unvested restricted share awards. Diluted earnings per share is computed by dividing net income attributable to MasTec by the weighted average number of fully diluted shares, as calculated under the treasury stock method, which includes the potential effect of dilutive common stock equivalents, such as issued but unvested restricted shares and/or outstanding but unexercised stock options. The Company has no remaining outstanding stock options; all options under the Company’s stock option grants were exercised in 2016. If the Company reports a loss, rather than income, the computation of diluted loss per share excludes the effect of dilutive common stock equivalents, as their effect would be anti-dilutive.

	us-gaap	Unapproved Change Orders Description UnapprovedChangeOrdersDescription	The Company may incur costs subject to change orders, whether approved or unapproved by the customer, and/or claims related to certain contracts. Management determines the probability that such costs will be recovered based upon engineering studies and legal opinions, past practices with the customer, specific discussions, correspondence or preliminary negotiations with the customer. The Company treats such costs as a cost of contract performance in the period incurred if it is not probable that the costs will be recovered, and defers costs or recognizes revenue up to the amount of the related cost if it is probable that the contract price will be adjusted and can be reliably estimated. As of September 30, 2017 and December 31, 2016, the Company had approximately $77 million and $17 million, respectively, of change orders and/or claims that had been included as contract price adjustments on certain contracts that were in the process of being resolved in the normal course of business, including through negotiation, arbitration and other proceedings. These contract price adjustments, which are included within costs and earnings in excess of billings or billed accounts receivable, as appropriate, represent management’s best estimate of contract revenue that has been earned and that management believes is probable of collection. As of both September 30, 2017 and December 31, 2016, these change orders were primarily related to contracts in the Oil and Gas segment. The Company actively engages in substantive meetings with its customers to complete the final approval process, and generally expects these processes to be completed within one year. The amounts ultimately realized upon final acceptance by its customers could be higher or lower than such estimated amounts.

Revenue from these contracts, as well as for certain projects pursuant to master and other service agreements, is recognized using the percentage-of-completion method, under which the percentage of revenue to be recognized for a given project is measured by the percentage of costs incurred to date on the contract to the total estimated costs for the contract. Such contracts provide that the customer accept completion of progress to date and compensate the Company for services rendered, which may be measured in terms of costs incurred, units installed, hours expended or some other measure of progress. Contract costs include all direct materials, labor and subcontracted costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and the operational costs of capital equipment. Much of the materials associated with the Company’s work are customer-furnished and are therefore not included in contract revenue and costs.</font></div><div style="line-height:120%;padding-bottom:12px;text-align:justify;text-indent:48px;font-size:9pt;"><font style="font-family:inherit;font-size:9pt;">The estimation process for revenue recognized under the percentage-of-completion method is based on the professional knowledge and experience of the Company’s project managers, engineers and financial professionals. Management reviews estimates of contract revenue and costs on an ongoing basis. Changes in job performance, job conditions and management’s assessment of expected contract settlements are factors that influence estimates of total contract value and total costs to complete those contracts and, therefore, the Company’s profit recognition. Changes in these factors may result in revisions to costs and income and their effects are recognized in the period in which the revisions are determined, which could materially affect the Company’s results of operations in the period in which such changes are recognized. For both the </font><font style="font-family:inherit;font-size:9pt;">nine</font><font style="font-family:inherit;font-size:9pt;"> month periods ended </font><font style="font-family:inherit;font-size:9pt;">September 30, 2017</font><font style="font-family:inherit;font-size:9pt;"> and </font><font style="font-family:inherit;font-size:9pt;">2016</font><font style="font-family:inherit;font-size:9pt;">, project profit was affected by less than </font><font style="font-family:inherit;font-size:9pt;">5%</font><font style="font-family:inherit;font-size:9pt;"> as a result of changes in contract estimates included in projects that were in process as of </font><font style="font-family:inherit;font-size:9pt;">December 31, 2016</font><font style="font-family:inherit;font-size:9pt;"> and </font><font style="font-family:inherit;font-size:9pt;">2015</font><font style="font-family:inherit;font-size:9pt;">. Provisions for losses on uncompleted contracts are made in the period in which such losses are determined to be probable and the amount can be reasonably estimated. The majority of fixed price contracts are completed within </font><font style="font-family:inherit;font-size:9pt;">one</font><font style="font-family:inherit;font-size:9pt;"> year.</font></div></div>

Key estimates include: the recognition of revenue and project profit or loss (which the Company defines as project revenue, less project costs of revenue, including project-related depreciation), in particular, on construction contracts accounted for under the percentage-of-completion method, for which the recorded amounts require estimates of costs to complete and the amount of probable contract price adjustments; allowances for doubtful accounts; estimated fair values of goodwill and intangible assets; acquisition-related contingent consideration and investments in equity investees; asset lives used in computing depreciation and amortization; fair values of financial instruments; accrued self-insured claims; share-based compensation; other accruals and allowances; accounting for income taxes; and the estimated impact of litigation and other contingencies. While management believes that such estimates are reasonable when considered in conjunction with the Company’s consolidated financial position and results of operations taken as a whole, actual results could differ materially from those estimates.</font></div></div>
