Well 5A Water Treatment improvements
Phase 3 - Final Design
Scope of Work
Draft 1 - 6108107
Purpose and Approach
The purpose of Phase 3 of the Well 5A Water Treatment Improvements Project is to prepare the
final design and eonstnietion documents for the City of Renton's planned Well 5 A treatment
facility. This construction documents will be submitted to the Department of Health (DOH) and
the City Council for project approvals and permits. As part of the design process, the HDR-
Kennedy/Jenks design team (Consultant) will provide technical assistance to the City for permit
applications associated with the project. The Consultant will also provide assistance to the City
during the construction bidding phase.
The overall approach is to produce key design deliverables by target dates needed for project
delivery. These target dates may change per the City's needs and/or changed project conditions.
The final design will be based on the basis of design developed in Phase 2 of the project.
The specific objectives, work elements, and budget for Phase 3 are more fully described in the
Scope of Work section below. At the end of Phase 3, the Scope of Work and budget will be
refined and adjusted for the Phase 4 - Assistance During Construction to meet the project
requirements and the City's needs.
The tasks and work elements to be performed by the Consultant are described below. Outlined
for each task are the objectives, work elements, responsibilities of the City, and
products/deliverables. Unless otherwise noted, all items listed under the "Work Elements"
section for each task will be performed by the Consultant. Work that is specifically not included
in this scope or work to be performed by the City is listed under the section "Work Not
