Design and engineering changes occurring subsequent to the issue of these documents have not been incorporated in this estimate. SUBTOTAL TRADE COSTS SUBTOTAL Bidding conditions are expected to be public bidding to pre-qualified (DCAMM certified) general contractors, open bidding for sub-contractors, open specifications for materials and manufacturers. The estimate is based on prevailing wage rates for construction in this market and represents a reasonable opinion of cost. It is not a prediction of the successful bid from a contractor as bids will vary due to fluctuating market conditions, errors and omissions, proprietary specifications, lack or surplus of bidders, perception of risk, etc. Consequently the estimate is expected to fall within the range of bids from a number of competitive contractors or subcontractors, however we do not warrant that bids or negotiated prices will not vary from the final construction cost estimate. This estimate includes all direct construction costs, contractor's overhead and profit and design contingency. Cost escalation is included until start date indicated.
