Additional as-built drawings have been provided on the solicitation on FBO. 35. For future building on this site (Bldg 432) utilities will be needed.

After review of the environmental survey documents and conducting the walk-thru, there is a need to re-inspect for asbestos and lead paint. Can the time clock for completion start after the re-inspections of the buildings? There may be additional materials to abate. That additional cost that will not be in our initial bid price and therefore, will need to be addressed as a change order prior to commencement of remediation and especially prior to notification to the State. Response: The period of performance for the project will commence upon issuance of the notice to proceed. No re-inspection of the facility will be conducted by the Government following award of the contract. Any re-inspection of the building and subsequent abatement will take place within that period of performance by the contractor.

As the site is known to have hazardous materials, no varying site conditions will be considered for removal of said material and no change order will be made. 43.
