This RFQ establishes a one‑year, not‑to‑exceed $50,000 unit‑price contract for parking‑lot sweeping services (including debris collection) for City of Spokane facilities, with prevailing‑wage compliance required. The contractor must respond to service requests within 24 hours, bill hourly rates for straight‑time, overtime, emergency and holiday work, and may incur additional costs for mobilization, travel, and disposal (the City pays $81.83 per cubic yard of debris). Invoices must be submitted within 30 days of service, include detailed service‑call information, and comply with Washington prevailing‑wage regulations. The contract may be extended up to three additional one‑year periods, each requiring updated prevailing‑wage rates and affidavits.
