Certain accounting estimates of the Company require a higher degree of judgment than others in their application. These include the recognition of revenue and income from construction contracts over time, the valuation of long-lived assets, goodwill and purchase accounting estimates. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.</span>
