About this file
This is Addendum #1 to Request for Proposal R-LD-27000 issued by Prince William County Schools (PWCS) Procurement Department in Virginia for Industrial Hygiene Services. The addendum, issued on September 23, 2026, clarifies response time requirements and service definitions for the requested comprehensive industrial hygiene and environmental consulting services. The original RFP was issued on September 10, 2026, with a sealed proposal due date of October 1, 2026, at 2:00 p.m. ET. The contractor will be expected to provide support including consultation with PWCS staff, site assessments, indoor air quality measurements, moisture evaluations, sampling when warranted, identification of contributing conditions, preliminary recommendations, and follow-up documentation.
The addendum establishes three distinct service categories with specific response time requirements. For emergency assignments, the contractor must acknowledge the request within one hour and mobilize qualified personnel to the affected PWCS facility within four hours unless otherwise directed. For non-emergency expedited assignments, the contractor must acknowledge the request within four business hours and provide onsite services within one business day, unless another timeframe is established by PWCS in the applicable task order. Routine services will continue to be scheduled under the applicable task order based on scope, priority, and required completion schedule. All other specifications, terms, and conditions from the original solicitation remain unchanged. Offerors must provide a signed acknowledgment of the addendum with their proposal submission on the due date and hour specified.

ADDENDUM # 1 DATE: September 23, 2026
REFERENCE: Request for Proposal: R-LD-27000 RFP Issue Date: September 10, 2026
Title: Industrial Hygiene Services Sealed Proposal Due Date: October 1, 2026, no later than 2:00 p.m. ET
All Offerors are advised of the following changes and clarifications in the referenced solicitation:
Questions & Responses:
1. Question: Can you clarify what support may be needed in section 3.8 and how quickly the contractor is required to respond to said event?
Response:
Support may include consultation with PWCS staff, site assessment, IAQ measurements, moisture evaluation, sampling when warranted, identification of potential contributing conditions, preliminary recommendations, and follow-up documentation.
For conditions designated by PWCS as an emergency, the Contractor shall acknowledge the request within one (1) hour and, when onsite response is requested, be capable of mobilizing qualified personnel to the affected PWCS facility within four (4) hours, unless otherwise directed by PWCS.
For non-emergency expedited assignments, the Contractor shall acknowledge the request within four (4) business hours and provide onsite services within one (1) business day, unless another timeframe is established by PWCS in the applicable task order.
2. Question: Can you specify what is considered to be an emergency and expedited response in section 7.12?
Response:
For emergency assignments, the Contractor shall acknowledge the request within one (1) hour and, when an onsite response is requested, be capable of mobilizing qualified personnel within four (4) hours unless otherwise directed by PWCS.
An expedited response refers to a non-routine assignment that, while not necessarily an emergency, requires a faster response or completion schedule than would normally be expected for routine task-order work.
Examples may include accelerated site assessments, sampling, analytical services, reporting, project monitoring, or other services needed to support an operational or project deadline.
For expedited assignments, the Contractor shall acknowledge the request within four (4) business hours and provide onsite services within one (1) business day, unless another timeframe is specified by PWCS.
Routine services will continue to be scheduled under the applicable task order, based on scope, priority, and the required completion schedule.
