Routine and On-Demand Maintenance Services for Hydrodynamic Separator (HDS) Trash Capture Devices

The City of Richmond is requesting a qualified contractor to perform both routine (twice‑yearly) and on‑demand maintenance of five Hydrodynamic Separator (HDS) trash‑capture devices located throughout the city’s storm‑water system. The work includes debris and sediment removal, flushing, inspection, disposal, traffic‑control coordination, and detailed reporting after each service event. The contract is a one‑year base term with two optional one‑year extensions, and the contractor must meet specified response‑time windows for on‑demand requests and maintain all required insurance and licensing. • Perform semi‑annual routine cleaning of all five HDS units (labor, equipment, disposal included). • Provide on‑demand cleaning within 5 business days (48 hours for urgent calls) after city authorization. • Handle waste disposal, traffic control, and submit post‑service reports (Exhibit C) with photos and condition assessments. • Supply required insurance (general liability, workers’ comp, etc.) and maintain a local business license. • Offer hourly rates for non‑routine labor and extra traffic‑control services, capped at 12 % of the routine lump‑sum unless a change order is approved.
