The City of Bellingham is soliciting sealed proposals for interior renovation and building-system upgrades at the Bellingham Central Library, including new layouts and finishes, mechanical, plumbing and HVAC work, and electrical and lighting improvements. Critical operational areas and building systems must remain functional during construction, with alternates covering first-floor restroom modifications, flex space, and a new help desk. The estimated price range is $4.42 million to $5.92 million, and voluntary pre-bid site visits are scheduled for September 22 and October 7, 2026.
