The Contractor shall perform all Work, including providing all Materials, in accordance with the requirements of the Contract. Dimensions and values required by the Contract are target dimensions or values . The Department will accept deviations from these targets within the tolerances required by the Contract . Materials and workmanship shall be uniform in character and shall conform to the target or to the middle portion of the tolerance range. The purpose of the tolerance range is to accommodate occasional minor variations from the target or middle portion of the tolerance range that are unavoidable for practical reasons . If the Contract requires a maximum or minimum dimension or value, the Contractor shall control the production and processing of Material and the performance of the Work so that the Material or workmanship is not of borderline quality or dimension. If the Contract does not specify a tolerance for a requirement, the Engineer will accept an I ndustry Standard tolerance. If the Engineer determines that Materials or workmanship are consistently of borderline quality, the Engineer may direct the Contractor to suspend operations and may declare future Work of borderline quality to be unauthorized Work in accordance with 1512, “Unacceptable and Unauthorized Work.”

The Engineer may accept alternative designs from those required for temporary construction provided that costs to the Department do not exceed those that the Department would have incurred with the design required by the Contract.
