Because of the nature of our projects, including contract owner inspections of the work both during construction and prior to acceptance, we have not experienced material warranty costs for these short-term warranties and therefore do not believe an accrual for these costs is necessary. Certain construction contracts carry longer warranty periods, ranging from two to ten years, for which we have accrued an estimate of warranty cost. The warranty cost is estimated based on our experience with the type of work and any known risks relative to the project and was not material during the years ended December 31, </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">2012</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">2011</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">2010</font><font style="font-family:inherit;font-size:10pt;">.</font></div></div>

Revenue in an amount equal to cost incurred is recognized prior to contracts reaching at least 25% completion, thus deferring the related profit. It is our judgment that until a project reaches at least 25% completion, there is insufficient information to determine the estimated profit on the project with a reasonable level of certainty. In the case of large, complex design/build projects we may defer profit recognition beyond the point of 25% completion based on an evaluation of specific project risks. The factors considered in this evaluation include the stage of design completion, the stage of construction completion, status of outstanding purchase orders and subcontracts, certainty of quantities of labor and materials, certainty of schedule and the relationship with the owner.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;padding-left:12px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Revenue from contract claims is recognized when we have a signed agreement and payment is assured. Revenue from contract change orders, which occur in most large projects, is recognized when the owner has agreed to the change order in writing. Provisions are recognized in the consolidated statements of operations for the full amount of estimated losses on uncompleted contracts whenever evidence indicates that the estimated total cost of a contract exceeds its estimated total revenue. All contract costs, including those associated with claims and change orders, are recorded as incurred and revisions to estimated total costs are reflected as soon as the obligation to perform is determined. Contract cost consists of direct costs on contracts, including labor and materials, amounts payable to subcontractors, direct overhead costs and equipment expense (primarily depreciation, fuel, maintenance and repairs). </font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;padding-left:12px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The accuracy of our revenue and profit recognition in a given period depends on the accuracy of our estimates of the cost to complete each project. Cost estimates for all of our significant projects use a detailed “bottom up” approach and we believe our experience allows us to provide materially reliable estimates. There are a number of factors that can contribute to changes in estimates of contract cost and profitability. The most significant of these include:</font></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;" rowspan="1" colspan="1"></td><td rowspan="1" colspan="1"></td></tr><tr><td style="vertical-align:top" rowspan="1" colspan="1"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><font style="font-family:inherit;font-size:10pt;">•</font></div></td><td style="vertical-align:top;" rowspan="1" colspan="1"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">the completeness and accuracy of the original bid;</font></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;
