About this file

This addendum document is issued by the Rivanna Water & Sewer Authority (RWSA) in Virginia for IFB # 448 regarding Airport Road Pump Station & Ground Storage Tank Improvements. The project entails increasing system capacity at the Airport Road Pump Station (ARPS) through the addition of pumping capacity within the existing station and the construction of new ground storage tank(s) at the ARPS site to support future growth in the northern service area. A non-mandatory online-only pre-bid meeting is scheduled for Tuesday, October 6, 2026 at 9:00 a.m. EST. This addendum constitutes Part I of a multi-part document series and provides clarifications, modifications, or additional requirements to the original invitation for bids.

The specific provisions contained within Addendum 03 Part I should be reviewed in conjunction with the original IFB # 448 solicitation documents to ensure comprehensive understanding of all pricing terms, evaluation criteria, technical specifications, and submission requirements. Bidders are advised to acknowledge receipt of this addendum as part of their bid submission to ensure compliance with all current solicitation requirements and to avoid bid rejection based on failure to address amendments to the original solicitation.
