Attachment_6_-_NE_Quadrant_Setback_Concept.pdf

This file is a conceptual design document for the Northeast Quadrant Setback Levee Project located at 1428 - 128th Street E in Pierce County, Washington, prepared in support of Pierce County Planning and Public Works Surface Water Management Division's request for qualifications from consulting engineering firms. The project encompasses architecture and engineering services for setback levee improvements across three quadrants (Northeast, Southwest, and Northwest), with qualifications due November 25, 2026. The selected consultant will develop an initial design and delivery strategy following a comprehensive review of all three quadrants, then prepare complete Preliminary, Specifications, and Engineering (PS&E) designs at five completion milestones: 15%, 30%, 60%, 90%, and 100%. The contract term is structured with renewal options available for up to five years, with specific renewal terms to be defined in the Professional Services Agreement.

Compensation shall be determined using unit-of-measure, milestone-based, or labor-based rates as detailed in Exhibit B, with annual budget adjustments permitted no more than once per year and capped at 5% based on the Seattle-Tacoma-Bellevue Consumer Price Index. The consulting firm must maintain commercial general liability and professional liability insurance of $1,000,000 per occurrence and $2,000,000 cyber liability coverage, with technology professional liability insurance where applicable. Prevailing wage requirements under RCW 39.12 apply to applicable public works components of these projects. The Exhibit B feasibility study from May 2023 provides the technical baseline and quadrant-specific design considerations necessary for project execution. The Professional Services Agreement (Exhibit A) establishes the contract framework and is governed by Washington law with venue in Pierce County Superior Court, subject to Washington Public Records Act obligations.
