Item No.: 10a_supp Meeting Date: February 24, 2026 T91 Uplands Redevelopment Post-Validation contract amendment 1 Action Requested Request Commission authorization for the Executive Director to approve funding to execute a Post-Validation Amendment to the alternative public works Progressive Design-Build contract, MC-0321389, for the T91 Uplands Development program (C800158, C801169, C801372) to further advance design, complete the development and negotiation of a Guaranteed Maximum Price (GMP), and perform some early work and procurement of long-lead items. The total requested for this action is $36,200,000 for a total project authorization of $46,300,000. 2 Vision and Purpose Develop new maritime industrial buildings with associated utility and site infrastructure and demolish several outdated buildings. New upland Port buildings will help sustain and support maritime industries and maritime supply chain. • Shortage of leasable light industrial building space in Ballard Interbay Northend Manufacturing Industrial Center (BINMIC) • Demonstrate support for Seattle's Industrial Lands policy • Retain port-dependent maritime tenants supporting vessel activity at Piers 90 & 91 • Support Maritime Innovation Center and other maritime innovation businesses • Make-up for demolition of obsolete warehouse space at T91 3 Project Area Phase 1 Phase 2: Pad Ready Demolition MAGNOLIA BRIDGE 4 Project Baseline Scope 1.

High High PDB validation and internal testing has identified potential issues that can be tracked in additional capital projects and the Risk Register Unknown Site Conditions The site is full of abandoned foundations and utilities that can impact construction timelines and cost. High High Partnering with a progressive design-build (PDB) team allows validation of the site and better understand what is in the ground. This can then be incorporated into schedule and the GMP for better cost certainty. Permitting time Permitting delays may impact schedule and cost. Med Med PDB project delivery will allow for early collaboration on design and permitting to the extent feasible. Coordination with other projects and seasonal demand at T91 There are many other projects scheduled on Pier 91 with similar timelines that may impact construction. Med Low Communication consultant will help coordinate the identification of on-going and upcoming construction work. Supply chain uncertainty Supply chain logistics could delay project delivery. Tariffs could impact ability to procure long-lead items and create uncertainty in pricing. Med High Adding cost contingency to the risk register to account for tariff price impacts. Early procurement of long-lead equipment in advance. Low Early engagement with SDOT to align expectations and mitigate approval delays. Additional coordination and work regarding the Magnolia Bridge railing is added to the Risk Register. Demolition of W-39 Project Risks The W-39 building is connected to the Magnolia Bridge.
