City of Everett,Washington I Reservoir 3 Structural Improvements PDB Project Progressive Design-Build Contract I Exhibit C. Phase 1 Scope of Services Note that the Washington Department of Labor and Industries considers access of the filled reservoir by boat to be a permit-required confined space entry. The City intends to install air monitoring equipment inside the reservoir that will allow the space to be classified as an Alternative Methods confined space. The City will provide the Design-Builder access to the reservoir interior, but all confined space entry plans, procedures, and safety equipment will be the responsibility of the Design-Builder. Access of the Reservoir 3 interior and any field investigations conducted therein will be subject to the water quality protection requirements identified in the Owner's Project Criteria (Exhibit B) Deliverables: 1. Field Investigation Plan (draft and final) 2. Photographic documentation of existing reservoir cover and valve vault conditions 3. Geotechnical Evaluation Report for geotechnical investigations conducted under this task. Task 4—Design Development and Documents Subtask 4.1 —Basis of Design Report and Design Approach/Concept Workshop Following the completion of field investigations and development of preliminary design and construction concepts, the Design Builder shall prepare a Basis of Design Report and conduct a Design Approach/Concept Workshop with the City. At a minimum, the Basis of Design Report shall include the following: 1. Project summary, features, goals/objectives, and requirements 2. Results of field investigations, including summary of locations of condition issues, extent of damage, and proposed repairs and improvements 3. Results of a preliminary seismic evaluation of the structure. 4. Relevant design standards and requirements, including Owner's Project Criteria and any proposed modifications 5. Preliminary structural, geotechnical, and seismic design criteria 6. Site constraints including constraints imposed by operating requirements, site and structure access, other site users, protection of existing above-ground and buried infrastructure, regulatory requirements, any applicable permits, and other factors. 7. Design concepts and other criteria for the Reservoir 3 cover repairs, ventilation improvements, valve vault improvements, and seismic upgrades, including: a. Design assumptions b. Recommended materials c. Demolition concepts and plans for managing debris d. Coating/sealant and corrosion protection requirements e. Recommended construction methods and constructability considerations that satisfy design criteria f. Concepts for construction reservoir access Page 6 of 15
