Management believes that its most significant estimates and assumptions have been based on reasonable and supportable assumptions and the resulting estimates are reasonable for use in the preparation of the consolidated financial statements. The Company’s significant estimates include estimates associated with revenue recognition on construction contracts, costs incurred through each balance sheet date, impairment of goodwill, intangibles, property and equipment, fair valuation in business combinations, insurance reserves, income tax valuation allowances, and contingencies. If the underlying estimates and assumptions upon which the consolidated financial statements are based change in the future, actual amounts may differ from those included in the accompanying consolidated financial statements.</span></div>
