For example, Submittal No. 3, Construction Schedule, ultimately required Carollo to retain the services of a specialty subconsultant, Construction Management Services, for the review of the Contractor's construction schedule. Submittal No. 16, Concrete Mix Design, required repeated submittal review and discussions with both the Contractor and concrete supplier in order to determine the acceptability of the concrete mix design. 7.3 Evaluate Change Orders Existing Scope: Evaluate a maximum of two change order requests, and if processed, ensure that the integrity of the original design intent has not been changed.
