RFB927940-04 - Addendum #2 (Reduced Size Format).pdf

This is Addendum #2 to Request for Bids (RFB) 927940-04 issued by the Iowa Department of Administrative Services for the WRC Decentralization Phase 4 and Fire Alarm Phase 3 project at the Woodward Resource Center. The addendum clarifies that the bid submission deadline remains Thursday, June 4, 2026, at 2:00 PM, correcting an error in Addendum #1. The project encompasses replacing steam and chilled water systems with new air handler units, replacing fire alarm systems, performing elevator repairs, and installing fire suppression systems in Linden Court Buildings A, B, C, and D. Prospective bidders must acknowledge receipt of this addendum in the IMPACS electronic procurement system to avoid disqualification. The addendum addresses questions raised during the pre-bid meeting, including clarifications on responsibility for removing security cameras and identifying active wiring (facility responsibility), provision of photographs of space above ACT ceiling tiles and roof locations for ductwork routing at Building D, and clarification that pipe demolition in the Linden tunnel is not included in the current project scope. Specific work responsibilities are delineated: BP 23-1 is responsible for foundations of ductwork supports and equipment pads, while BP 09-1 handles grading and remaining concrete work.

The addendum modifies the original bidding documents dated March 27, 2026, and includes changes to electrical drawings, specifically to Drawing 00-E012 (Electrical Site Plan – Linden Court), which now requires the furnishing and installation of a new main breaker rating plug capable of adjustment from 0.95 to set the trip setting to 1900A. Two attachments are provided: photographs of the space above the ACT ceiling and documentation of the ductwork routing location for the air handler unit serving Building D. Bidders must review full-size drawings available through IMPACS and acknowledge receipt of all addenda as part of the certification requirements for proposal submission.
