This document is an Addendum (No. 1) dated 4/14/2025 issued by Southeastern Louisiana University for a roofing replacement project at Garrett Hall. The addendum provides clarifications from a mandatory pre-bid conference, including specifications that the project requires furnishing labor and materials for roof replacement. Key requirements include using a licensed Louisiana contractor, no existing warranties for the current SBS roofing system, and specific work hours between 6:00 am until 6:00 pm. The document also includes details about bid security requirements, with bidders needing to provide a bid bond or security of at least 5% of the base bid, and specifies that Sika Sarnafile PVC membrane is not an approved substitute material.

The addendum also includes an attached pre-bid conference sign-in sheet and a detailed specification for an Infrared Roof Moisture Survey. The survey requirements mandate engaging an Independent Testing Agency with a Certified Thermographer to perform a non-destructive infrared roof moisture survey, documenting sub-surface moisture locations and extent. The testing agency must have a minimum three-year record of satisfactory experience on similar projects. The survey will involve high-resolution infrared thermal imaging, performed at night following a sunny day, with specific technical requirements for equipment (long wave infrared spectrum) and comprehensive reporting of weather conditions, testing principles, procedures, imagery, and detailed findings including total roof footage inspected and percentage of wet areas detected.
