RFSQ GC/CM Services W365 - WSLE Alaska Junction Station

The Central Puget Sound Regional Transit Authority (Sound Transit) is soliciting Statements of Qualifications under RFSQ GC/CM Services W365 for a General Contractor/Construction Manager to deliver preconstruction and construction services on the West Seattle Link Extension Alaska Junction Station, with SOQs due December 1, 2026 at 2:00 p.m. PT through the Sound Transit Vendor Portal at www.biddingo.com/soundtransit. No DBE goal has been established for this solicitation following the October 3, 2025 federal interim final rule, though Sound Transit encourages participation from Small Businesses and firms reflecting all communities in its marketplace.

The project comprises the Alaska Junction Station, associated roadway, site and utility work, and interfaces with several other contracts, located in Seattle along SW Alaska Street between 40th Avenue SW and 41st Avenue SW. The GC/CM must manage complex phasing and sequencing with the W350 West Seattle Tunnel contractor and coordinate with the W600 Trackwork and Systems contractor. Interface management extends to King County Metro, Seattle Department of Transportation, Seattle City Light, and Seattle Public Utilities. Proposers must demonstrate bonding capacity for labor, material, and tax payment bonds and performance bonds, each equal to 100 percent of the Total Contract Cost, with sureties rated A-VII or better by A.M. Best and listed in U.S. Department of Treasury Circular 570. The project is subject to FTA Master Agreement and Circular 4220.1G requirements, prevailing wage rates at construction contract execution, and a Project Labor Agreement.

Preconstruction services are estimated at $5 million to $10 million over 24 months, from Q1 2027 through Q3/Q4 2028. The construction services contract is estimated at $225 million to $300 million over an anticipated five-year construction period beginning June 2028, exclusive of Washington State sales tax and preconstruction services. Funding is anticipated from the U.S. Department of Transportation Federal Transit Administration.

Evaluation allocates 400 points to the SOQ, 500 points to interviews, and 100 points to final price proposals. Sound Transit intends to shortlist three proposers, not to exceed five. If Sound Transit cannot reach agreement with the highest-ranked proposer on the Maximum Allowable Construction Cost (MACC), it may suspend or terminate negotiations, and the GC/CM will have no claim against Sound Transit. Sound Transit will not accept late SOQs, and SOQs become public records after an award recommendation goes to the Sound Transit Board, except for materials marked confidential that meet statutory exemption requirements.
