Demolition of Buildings 6, 11, 14 & 17 Government Responses to Industry Questions

1. Are buildings 6, 11, 14, & 17 currently with electrical power? If in fact, they have power what is going to happen to expose electrical panels or sub panels after demolition?

· The buildings have power. As part of the demolition, all electrical components attached to the building must be demo as well. Main power source for each building must be disconnected from the facility and main feeder must be pulled and disposed. All underground electrical pipes must be cap at the surface. All electrical works must comply with UFC 3-560-01 Electrical Safety.

2. Buildings 6, 11, 14, & 17: For the benefit of everybody, can you please provide an estimated amount of square footage or incorporate an "Allowance Item" amount, for Lead-Based Paint and Asbestos mitigation? We think there is no way we can estimate that due to the few information given. If for example, we assume all the buildings are positive to Lead-Based paint and they are not, it will be an overburden in cost for the Owner.

· The square footage for each bldg. is in the SOW. Assume the following height for the facilities: Bldg. 6. 26ft & Bldg. 11, 14, 17 10 ft. There is no survey on asbestos or LBP on those buildings. Therefore, we request a survey. Building 6 and 11 were built prior 1978 assume there is LBP on them. Building 14 and 17 were built after 1978 by this time LBP was prohibited on new construction. However, a LBP survey must be performed. Assume there is asbestos on all buildings.
