SOW - 401MB Elastomeric Roof Coating.docx

Statement of Work Building 401MB Elastomeric Roof Coating USDA, Ames, IA 7-10-20

Project Requirements:

Background:

The NCAH Building 401 (also referred to as the MB building) was constructed as a temporary laboratory facility in 2002. The existing roof of Building 401MB is in poor condition. Due to wind and various weather conditions over the years, the roof has lost many of its original fasteners which has become an integrity concern and these missing fasteners have become potential leaks for water. The general scope of this project is to inspect the entirety of the roof of Building 401MB, replace any missing fasteners or brackets and seal the entire roof (upper and lower) using an elastomeric sealant as described below to ensure that water will not enter the building and damage any items inside.

Scope:

The general scope of this project is as follows:

1. Inspect all 11,900 S.F. of roofing (upper and lower) for defects (loose fasteners, missing fasteners, damaged pieces of roofing, etc.)

2. Inspect gutter system to ensure it will drain water as originally designed. Repair any sections or areas as needed. See attached document “Original Downspout Specifications” for reference to material and fasteners.

3. Replace any and all fasteners that have become loose and/or are missing altogether. See attached document “Original Steel Roof Specifications” for reference to materials and fasteners.

4. Seal any and all fasteners with a sealant that is designed for this type of application and environment. Sealant shall be an ERsystems® H.E.R. flashing grade single component moisture-cure polyurethane roof sealant or approved equivalent.

5. Power wash and clean all 11,900 S.F. of metal roofing per the sealant manufacturer’s application requirements prior to sealing the roof to ensure surface is free of contaminants.

6. Seal any and all seams in metal roofing with a sealant that is designed for this type of application and environment. Sealant shall be an ERsystems® H.E.R. flashing grade single component moisture-cure polyurethane roof sealant or approved equivalent.

7. Seal around any and all roof penetrations with a sealant that is designed for this type of application and environment. Sealant shall be an ERsystems® H.E.R. flashing grade single component moisture-cure polyurethane roof sealant or approved equivalent. See attached product specifications.

8. Seal all 11,900 S.F. of metal roofing (upper and lower) with an elastomeric sealant that is designed for this type of application and environment. Sealant shall be an ERsystems® H.E.R. flashing grade single component moisture-cure polyurethane roof sealant or approved equivalent.

9. Contractor will follow manufacturer’s recommended method of application for all products used.
