The purpose of this amendment (0001) is to incorporate RFI questions with responses, Revise Statement of Work, and add attachments:

A. Incorporate the following Offeror requests for information (RFIs) with government responses:

[KTR RFI 01] “Will the Government provide the as-built drawings for Building 2A, including utility lines and service feeds, i.e., water, gas, compressed air, electrical, etc., going back to Building 2?”

[GOV RESPONSE 01] NIST has a drawing set dated March of 1989 containing drawing information for the building itself (nothing recent), however we do have updated survey drawings for the locations of buried services to B2A. In either case, NIST will make this information available for bidder reference.

[KTR RFI 02] “Will the Government confirm that the (2) ancillary structures which are plan west and plan northwest of Building 2A are to remain?”

[GOV RESPONSE 02] The bike racks, concrete pad and metal canopy structure will remain and should be protected during the demolition construction. The smaller exterior storage cage shall be removed as part of this contract.

[KTR RFI 03] “Will the Government confirm that the request for sidewalk providing access to Building 2A will be routed between Building 2A and the ancillary structure plan west of Building 2A to connect to the path at the north?”

[GOV RESPONSE 03] The sidewalk to be installed should extend from where the existing walks are on the south side of the building, northward toward where the sidewalk to the north of the building is. The new sidewalk flat work should extend the length of the location where new parking spots are to be installed/stripped, such that it is continuous over the entire distance where the new parking spaces will be constructed. Refer to site standards for sidewalk concrete requirements.

[KTR RFI 04] “We are reviewing the Building 2A demolition scope and related demolition specifications. The documents include asbestos-containing material emergency response procedures and also state that hazardous materials may be present in buildings or structures to be demolished. The specifications also reference a hazardous materials report on file for review/use. Could the Government please provide the hazardous materials/asbestos report referenced in the specifications? Please also confirm whether asbestos abatement, lead abatement, PCB removal, universal waste removal, or any other hazardous material remediation is included in the contractor’s demolition scope, or if those items will be handled separately by the Government.”

[GOV RESPONSE 04] Upon further internal coordination at NIST, we do not have an ACM report for Building 2A. As such, please provide pricing as if there is no known ACM in B2A, where ACM can be investigated and a report provided for further coordination with the awarded contractor team as part of a modification to the awarded contract at a later point in time

[KTR RFI 05] “Can wet utilities be capped at the foundation and abandoned in place?”

[GOV RESPONSE 05] Existing wet utilities shall be cut and capped per the SOW (building interior, not at foundation). It is acceptable for existing below grade piping to be abandoned in place, once capped and safed off inside of Building 2 or at source. Fill the abandoned line with self-leveling non-shrink grout or flow fill to 3psi, or approved alternative based on the submitted mix. Survey the capped end to document the location and the depth of the abandoned utility. Survey information to be provided to NIST when completed.

[KTR RFI 06] “Can the caissons be cut off 2 feet below grade?”

[GOV RESPONSE 06] All existing concrete footing walls, caissons and otherwise concrete foundations shall be removed entirely. NIST plans new building construction at the Building 2 and Building 2A locations in the future.
