When referring to the Statement of Work, specifically Building 314, it states “Replace lower roof with standing seam metal roof color to match the red roof on the Mission Training Center. Please see standing seam metal roof specifications.” We cannot locate the standing seam metal roof specifications. Also, on page 41 of 56, in the Solicitation, it references a Metal Roof Specification, but is not included within the solicitation nor is it shown on the beta.sam.gov website. Please advise if there is a specification for the new standing seam roof listed in the Statement of Work and Solicitation.

The metal roof specifications are now attached to the solicitation on beta.sam.gov

On Building 230, the SOW calls to re‐caulk all seams at flashings and interfaces. It has been our experience that re‐caulking will not prevent water from entering the structure.
