Industrial Hygiene Services

Prince William County Schools is requesting proposals for comprehensive industrial hygiene and environmental consulting services under RFP R-LD-27000, with proposals due October 1, 2026 at 2:00 p.m. ET. Addendum 1, issued September 23, 2026, establishes three service-response tiers with specific performance requirements that are now part of the solicitation.

The scope spans industrial hygiene assessments, site assessments, indoor air quality measurements, moisture evaluations, sampling when warranted, identification of contributing conditions, preliminary recommendations, and follow-up documentation. The contractor must distinguish between emergency, expedited non-emergency, and routine assignments. Emergency requests require acknowledgment within one hour and on-site mobilization of qualified personnel within four hours unless otherwise directed. Non-emergency expedited assignments require acknowledgment within four business hours and on-site services within one business day, unless PWCS establishes an alternative timeframe in the task order. Routine services are scheduled under task order based on scope, priority, and completion schedule. Vendors must demonstrate experience with K–12 educational facilities, familiarity with OSHA regulations and Virginia Department of Labor standards, and capability to provide responsive on-call support.

The RFP may include set-asides or preferences for small businesses, women-owned businesses, or Virginia-based vendors in accordance with state and local procurement policies. Pricing is structured according to the vendor's submitted fee schedule and may include hourly rates, project-based fees, or retainer arrangements. No estimated contract value or term length is specified. Offerors must provide a signed acknowledgment of Addendum 1 with their proposal submission.
