City of Everett,Washington I Reservoir 3 Structural Improvements PDB Project Progressive Design-Build Contract I Exhibit B.Owner's Project Criteria Criterion Requirement Reservoir 1. There are three existing hatches in the Reservoir 3 cover; one for human Access access that includes a stairwell into the reservoir, and two for equipment. Design-Builder may propose locations for additional temporary openings in Reservoir 3 for City consideration and approval. Any temporary openings shall be repaired and sealed appropriately after completion of cover repair work. Any modifications to the cover or side walls must be stamped by a Structural Engineer. 2. There are buried structures and utilities on-site (e.g., valve vault, reservoir bypass pipe, etc.). The Design-Builder shall identify locations of buried infrastructure and plan on-site activities and paths of travel so as to avoid damage to buried infrastructure. 3. 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 will have the Everett Fire Department perform an evaluation of the atmospheric conditions inside the reservoir prior to, but on the same day of, pre-Proposal site visits. Confirming suitable atmospheric conditions allows the space to be temporarily classified as an Alternative Methods confined space. 4. Prior to site investigations conducted during the design phase, 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. Work 1. There are homes and businesses located adjacent to the Reservoir 3 site. The Restrictions Design-Builder shall comply with all local codes, ordinances and requirements with respect to noise, light, dust control, and work hours. If night work is proposed, a plan for mitigating impacts of night work on neighboring properties is required. Reservoir Work 1. The Work associated with the Phase 2 Services will consist of two primary and Vault Work components: (1)The Work associated with the interior of Reservoir 3, including Limitations and all in-water activities (the"Reservoir Work") and (2) the Work associated with Allowable the valve vault (the"Vault Work"). Construction 2. The Design-Builder shall not perform the physical Reservoir Work and the Vault Work concurrently, and shall perform all physical Reservoir Work within the Windows date range identified in Section 6.2.1 of the PDB Contract.
