If they are requiredthey must be on the form.Response: Unit pricing for this work will be negotiated as part of the final contract.4PB-005 Question:Add Alternate 2 Specification 012300; the wording regarding ACM removal is contradictory. Note 4tells us that all roofing material is assumed to be ACM. However the paragraph regarding theallowance is requesting a credit for removal of non-ACM roofing. If it is ACM we are not removing it inthe first place. If you want a credit then the contractor must assume a non-ACM roof. The same goesfor assumed ACM pipe insulation.Response: Roofing material is assumed to be asbestos containing but has not been tested and shallbe priced under the Alternate for removal as non-ACM. In the event that it is not asbestos containing,roof will be removed as part of the agreed alternate pricing excluding the allowance. Allowance fundswill be used if the roof is found to be ACM, in which case the cost will be the premium unit price forremoval as ACM over and above standard removal.Addendum No. 2 - Page 3 of 6
