Contractors must be registered in Washington State as a construction contractor and possess equipment including a PC-120 track-mounted excavator or larger with a toothed bucket and thumb attachment. The solicitation requires contractors to submit proposals by March 20, 2025, at 1700 PD, with questions due by March 5, 2025. Proposal evaluation will likely include contractor qualifications, equipment capabilities, and references from 2-3 recent similar projects.
