WPCF Headworks Replacement Project Scope of Work 54 Phase 650 Intermediate Design Objective: Obtain approval from the City on the complete arrangement of the proposed headworks design. This is considered the design scope freeze point. Civil, structural, architectural, and process mechanical models are largely complete and all major design decisions have been reached and approved. Electrical, instrumentation, and building mechanical models have been progressed. Major construction documents, drawings, and specifications have been progressed. This phase includes addressing preliminary design comments provided by the City, GC/CM, and other stakeholders. A revised cost estimate and construction schedule will be provided under Phase 350. Following completion of the intermediate design phase, the project team will reassess the scope and budget to reflect the actual headworks facility requirements. At that time, an amendment will be issued to incorporate revised scope elements based on the confirmed design criteria and facility configuration, adjust the project budget to align with the updated scope, and identify and formally include any work previously considered out-of-scope due to initial design uncertainties. The initial project contract scope of work ends at Phase 650. Subsequent design phases 700 Phase 700 Final Design Phase 700 Scope of work is not included in the initial design contract. This work will be added through request. Objective: The final design phase advances the intermediate design package to a complete set of engineering plans and technical specifications. The final design reflects a comprehensive and detailed representation of the headworks facility and will serve as the basis for developing the GC/CM GMP and a final constructability review for development of the bid documents. The final Design documents will be submitted to the City, permitting agency(ies), and other stakeholders for review and comment. A Class 1 cost estimate and construction schedule will be developed under Phase 350. Regulatory coordination will be completed under Phase 100 Task 130. Phase 710 Bid Documents Phase 710 Scope of work is not included in the initial design contract. This work will be added through request. Objective: The bid set phase advances the final design documents to bid ready status. This phase includes updating the final design based on comments from permitting agency(ies), City, GC/CM, and other stakeholders. This phase includes a final QAQC step to check for project completion. The following table summarizes the discipline specific tasks included in each of the preliminary through detailed design phases. Structural design is scoped under Phase 300 Task 310. The narrative sections below the table summarize the general task specific activities.
