Question 5: Reference is made to the demolition of Building 609. Please confirm whether there are any known asbestos-containing materials

Answer 5: Hazardous materials abatement shall be included as part of the lump¿sum demolition scope. The Government¿s current information indicates that Building 609 contains limited known hazardous materials; however, this information is not considered exhaustive. For the purpose of establishing a basis of design and ensuring consistent pricing, the Contractor shall include in the lump¿sum price a complete hazardous materials abatement effort based on the following assumptions:

The Contractor shall assume discovery of typical quantities of asbestos¿containing materials (ACM), lead¿based paint (LBP), and other standard building hazardous materials consistent with structures of similar age and construction. Upon award, the Contractor shall perform a full hazardous materials survey by a licensed environmental professional to verify actual field conditions. If the verified conditions show less quantity than assumed, the

Contractor shall credit the Government the difference through a deductive modification. If the verified conditions show more quantity than assumed, the Contractor may request an equitable adjustment only for the documented, measurable overage. All abatement pricing shall be itemized with quantities, unit rates, and supporting documentation to allow Government validation.
