Pasco staff and the project construction manager told the council on June 9 that the Lewis Street overpass project is essentially complete for vehicle traffic but requires further warranty and punch-list work that will extend the construction contract and prompt a proposed amendment for additional construction-management services.
Michael Ullman, the city's project manager for the Lewis Street Overpass, said the bridge opened to traffic in April 2024 but the construction contract remains active while the contractor addresses cosmetic and functional corrective items. Ullman said recent work will include repair of cracking in some wall panels that Hill engineers have attributed to minor settlement, corrective action on expansion joints at each bridge end, final punch-list tasks and a plant-establishment period during which landscaping must be replaced as needed.
WSP, the project's construction manager, has requested a supplement (amendment) of about $100,000 for inspection and closeout services. Ullman noted the original WSP contract was about $1.85 million and that the amendment would raise overall CM fees to roughly $3.07 million, driven primarily by schedule extension and added scope; he said WSP's specialty scheduling and testing work helped mitigate larger delay costs during construction.
Ullman said the city has contract remedies available: liquidated damages and retained contract amounts that can be used to offset some CM costs. He and staff indicated some retainage remains and that parts of the contractor payment could be held until corrective work is complete. Councilmembers asked whether the project would require another council request; Ullman said the city expects this to be the final amendment and that the contractor has agreed to supply replacement materials and perform corrective work under the existing contract.
No contract amendment was executed at the workshop. Staff said they will return with final figures and will pursue offsets from the contractor to mitigate the requested CM amendment where appropriate; Ullman said corrective work will be staged to avoid full bridge closures, using single-lane traffic controls while repairs proceed.
