This is Addendum No. 9 to Contract No. 98587 issued by the Washington Suburban Sanitary Commission (WSSC) Procurement Department for the Anacostia II Wastewater Pump Station (WWPS) PLC Upgrades project. The addendum, dated March 24, 2026, extends the bid submission deadline to April 9, 2026, at 2:00 p.m. EST and modifies project requirements by adding revised electrical drawings (E-Revision 1 Electrical Drawings), detailed underground distribution system specifications (F-16375 Underground Distribution System) regarding conduits including path, lengths, and underground installation details, and supplemental pictures addressing cyber security requirements (Q.15 Sub-Question 4). The addendum consists of one page and requires bidders to acknowledge receipt in accordance with Part I, Article 8 of the contract documents; failure to do so may result in bid rejection.

The addendum incorporates three attachments as binding contract documents: the revised electrical drawings, the underground distribution system specifications, and the cyber security requirement pictures. Bidders must review these materials and submit responsive bids reflecting the clarifications and additional requirements outlined in this addendum. No pricing adjustments, set-asides, or funding modifications are addressed in this addendum document; it serves solely as a clarification and supplementation of technical specifications and security requirements for the ongoing procurement process.
