This is a service / maintenance or supply contract in Seattle, Washington. Contact the soliciting agency for additional information.

The Seattle Public Library seeks a contractor to provide professional window cleaning services to clean and restore clarity to the glass curtain wall and entranceways for the Central Library at 1000 Fourth Ave., Seattle, WA. The building is a unique, iconic structure with complex geometry, differing from common mid-to-high rise architecture, and requires companies with specialized knowledge and experience, specifically with negative angle overhang conditions. Many of the surfaces have work zones with no vertical faces, requiring open-air suspension rigging. The contractor is to provide all materials, equipment, and labor for a twice-annual exterior window cleaning service agreement per the specifications outlined for the Central Library. Only one contract will be awarded, though the Library reserves the right to make multiple or partial awards. deadline for Questions:November 19, 2025, 5:00pm
