Addendum No. 2.pdf

Addendum No. 2 is issued for Invitation for Bid (IFB) 2024-W-003 for a TP1 Roof Replacement project by Pueblo Water Municipal District (PWMD) in Colorado. The addendum modifies Section 1.15 of the original bid documents to specify that the roof shall be designed to resist wind uplift of 115 mph per Pueblo Regional Building Department's criteria. The project involves comprehensive roof renovation, including demolition of existing modified bitumen roofing, installation of a new TPO Mechanically Attached Roofing System with RhinoBond TPO Welding Plates, and associated roofing accessories across multiple roof areas.

The project requires detailed technical specifications, including installing fire-treated wood blocking, EPS flute filler insulation, cover board, and a 060 mil white TPO membrane system. The contractor must provide a 5-year workmanship warranty and a 20-year NDL Manufacturer's warranty covering materials and labor. Additional requirements include coordination with an electrician for electrical work, careful handling of existing lightning protection systems, and daily clean-up of project debris. The addendum provides photographic documentation of the existing roof conditions and installation details, which will help bidders understand the scope and complexity of the roof replacement project.
