Commentary
Allowances, if used, are not a true definition of the cost of work to be performed. By nature, an allowance is only an estimate and placeholder in the bid. Once the actual work is defined, the actual cost can be provided. It must be recognized that the actual cost can be higher or lower than the allowance. See Section 9.4. Allowances required by the contract documents or proposed by the bidder should be as thoroughly defined as practicable as to the distinct nature of the work covered by the allowance, including whether the allowance is to include materials only, fabrication costs, and/or erection costs.
