Notice of Intent for Utilization of (4) processes:

1. Alternative Mechanical Subcontractor Selection Process (MC/CM)
2. Alternative Electrical Subcontractor Selection Process (EC/CM)
3. Alternative Civil Subcontractor Selection Process (SC/CM)
4. Alternative Structural Concrete Subcontractor Selection Process (SC/CM)

Hoffman Construction Company of Washington (hereinafter referred to as the GC/CM) has been selected as General Contractor/Construction Manager (GC/CM) for the Port of Seattle Industrial Wastewater Treatment Plant (IWTP) Enhancements project MC-0321787.

The IWTP project includes installation of a pre-treatment system, increase storage capacity for high BOD, and upgrade the existing mechanical and electrical systems as required for a fully operational Industrial Waste Treatment Plant. The preconstruction of the overall project commences in September 2025 and is planned to end in Q1 of 2027. The overall project consists of scope as listed below with work commencing in Q1 2027 and completing Q3 2029:

1. Addition of a new on-site biological “aerated gravel bed” (AGB) treatment system to allow discharges of treated industrial wastewater to Puget Sound in accordance with NPDES permit discharge limitations.
2. Addition of a 5 Million gal fully buried prestressed concrete storage tank at the AGB site (“AGB Tank”) to expand high BOD industrial wastewater storage capacity.
3. Splitting existing Lagoon 3 (low BOD storage) into two lagoons using a berm, resulting in a new high BOD lagoon (“Lagoon 4”) and a reduced size low BOD lagoon (“Lagoon 3”).
4. Realignment of the existing Puget Sound outfall to go around the proposed expanded footprint of Lagoons 3 and 4.
5. Modifications to existing IWTP dissolved air flotation (DAF) system, including replacement of DAF units and associated infrastructure with larger capacity units.
6. Modifications to existing IWTP solids handling system, including replacement of the existing decant tanks with a gravity thickener unit.
7. Modifications to controls and flow routing schemes to integrate new and existing infrastructure, as detailed in Section 7 of the Basis of Design Report.

The GC/CM intends to select the mechanical subcontractor utilizing an alternative procurement method (MC/CM) in accordance with the provisions of RCW 39.10.385.

The GC/CM also intends to select the electrical subcontractor utilizing an alternative procurement method (EC/CM) in accordance with the provisions of RCW 39.10.385.

The GC/CM also intends to select the civil subcontractor utilizing an alternative procurement method (SC/CM) in accordance with the provisions of RCW 39.10.385.

The GC/CM also intends to select the structural concrete subcontractor utilizing an alternative procurement method (SC/CM) in accordance with the provisions of RCW 39.10.385.

The reasons for utilizing these alternative procurement processes include, but are not limited to, the following:

1. Provide preconstruction services including cost estimating, scheduling, phasing logistics, collaboration with the design consultants and assistance in the most cost-effective selection of materials and building systems related to the Mechanical, Electrical, Civil and Structural Concrete scopes of work.
2. As a Key Project Partner, MC/CM, EC/CM & SC/CM Civil and SC/CM Structural Contractors will participate in development of construction and phasing plans to minimize impacts to the active treatment plant includes researching existing panels and circuits that will be included in the upgrade.
3. Participate in constructability reviews that will maintain desired levels of quality, minimize changes to the Work, and keep the Project on schedule and within budget. Review the work packages and perform constructability analysis of the design documents and constructability reviews at key milestones such as 30%, 60% and 90% as needed.
4. Participate in identification of products and methods for Value Engineering (VE) for all scopes of work and engineering systems for life cycle cost design for Mechanical and Electrical scopes of work.
5. Participate in Building Information Modeling (BIM) meetings to coordinate complex Mechanical, Electrical & underground systems with the structure, other building systems and existing conditions. BIM is to be utilized from the preconstruction services phase through commencement of design through building commissioning and final completion as a tool for collaboration, information sharing, estimating, planning and coordination.
6. Participate with Project Partners to complete the design deliverables. As the design progresses, the content, format, schedule and review process of the design deliverables will be established by the Project Partners in accordance with the needs of the project. Goals include principles to eliminate waste, minimize cost, maximize efficiency and achieve the Port’s program and quality objectives.
7. Risk management – be an active participant in identifying and mitigating project risks. Includes participating in identification and early procurement of long-lead specialty, mechanical and electrical equipment.

All interested parties are hereby notified that a public hearing in accordance with RCW 39.10.385 will be held at 10:30 am PST, May 2, 2025, at the Seattle office of Hoffman Construction Company of Washington, 600 Stewart Street, Suite 1000.  Interested parties may also attend the public hearing virtually utilizing the Microsoft Teams link utilizing the following information:
