Construction drawings shall be in accordance with the 2022 California Building Code. JS&TM will prepare detailed construction cost estimate of the proposed lake improvements including construction quantities and unit costs. The quantities will be developed based upon construction item callouts from the Lake Plans and Specifications package. Unit costs will be based upon recent project cost information for similar projects in Southern California. The Construction Cost Estimate will be provided to the client to use as the Engineers Estimate for bidding. Construction Documents (CDs) shall include finalizing plans and specifications from the Design Development phase. This includes the provision of detailed engineering and construction drawings that will serve as the basis for both bidding and construction by a general contractor. 1S&TM will prepare technical specifications for all components listed above in CSI (Construction Specifications Institute) format. JS&TM will coordinate language between the general and technical specifications to ensure conflicts Thornton Park Lake Circulation Study and Renovations Page 12
