C07230 ADD #2.pdf

This document is Addendum No. Two for the Hemlock Filtration Plant project (Project No. 21009) issued by the City of Rochester's Department of Environmental Services, Bureau of Architecture and Engineering. The addendum, dated April 14, 2025, provides clarifications and instructions to bidders for Invitation to Bid No. C07230, with two primary instructions: to review attached clarifications to drawings and specifications, and to sign and return the addendum with the bid proposal. The bid opening date and time remain unchanged.

The addendum includes five key clarifications: (1) specifying responsibility for roofing work under the General Construction Contract, (2) confirming buffer tank insulation requirements, (3) clarifying platform responsibilities over the filter tank for different contractors, (4) correcting the bid date to 4/15/25, and (5) confirming Temiron as an accepted manufacturer for Outdoor, Semi-Custom Air Handling Units. These technical clarifications are designed to provide precise guidance to potential bidders and ensure a clear understanding of project specifications and contractor responsibilities for the HVAC upgrades at the Hemlock Filtration Plant.
