Cleaning Tunnel Surfaces of Likelike Highway

The Hawaii Department of Transportation is seeking bids to clean the tunnel surfaces on the Likelike Highway, specifically for the Wilson Tunnel inbound and outbound sections. The work involves removing debris, applying mortar and mastic, and installing glazed‑tile wall panels as detailed in technical drawings. Two separate line items each quantify two units of cleaning services, indicating a need for comprehensive interior tunnel cleaning and finish work. • Scope includes cleaning of tunnel surfaces for both inbound (Honolulu‑bound) and outbound (Kaneohe‑bound) directions of the Wilson Tunnel. • Required tasks: removal of contaminants, mortar/mastic application, tile installation, and trim work per provided specifications. • Attachments provide technical drawings, product brochures, and mandatory instructions to guide vendors on the exact methods and materials required.
