98 7-Sept-11 There has been some confusion regarding drawing S606 for Bldg.

106. First can you please confirm what the abbreviation ‘ATPF’ stand for? Second, we are assuming that these openings occur at each window opening as the opening sizes correspond with the architectural window schedule. Can you please confirm that these frames occur at every new and existing window opening on Bldg 106. Also, what framing is required throughout the blast resistant curtain wall? A plan showing these frames in elevation would be the easiest way to make this clear for all bidders.

AT/FP stands for Antiterrorism Force Protection. See UFC 4-010-01. These frames are required for all windows in Building 106.

There is an elevation view on Drawing S608 that depicts the steel frames for the curtain wall support. Architectural drawings depict the steel as well on Drawing A310, A311 and A604.
