Description

The King County Library System is seeking a qualified general contractor to execute a full interior renovation of the 22,600‑sq‑ft Kent Library. The library will be closed for the duration of construction, and the contractor must deliver demolition, new partitions, ceilings, finishes, restrooms, accessibility upgrades, and comprehensive upgrades to structural, mechanical, electrical, plumbing, fire‑protection, low‑voltage, and life‑safety systems. Coordination of owner‑furnished library shelving, furniture, and technology is required, as well as all testing, inspections, permits, and close‑out documentation to deliver a fully operational facility. The project budget is estimated between $3.25 M and $3.9 M, with a contract time of five months after notice to proceed. The bid process is conducted entirely online via the OpenGov portal, with no pre‑bid meeting or site visit, and a submission deadline of 10 AM on 2 Nov 2026.

Budget estimate

$3,250,000 – $3,900,000

The solicitation lists an owner‑estimated base bid range of $3.25 million to $3.9 million. Assuming the winning contractor’s profit and overhead are embedded in the bid, the expected revenue for the contractor will fall within that range. Factors influencing the final amount include any change orders, the extent of unforeseen site conditions (e.g., asbestos remediation), and the contractor’s ability to meet the five‑month schedule without penalties.
