REQUEST FOR PROPOSAL <br />STRUCTURAL PLAN CHECK SERVICES <br />1001 NORTH BROADWAY PROJECT <br />SCOPE OF WORK <br />Review and approved the structural part of the 37-story office tower at 1001 North <br />Broadway with deferring the following items from the first submittals: cladding, <br />equipment anchorage, stairs and elevators. <br />2. Also assuming that the building configurations, structural systems & framing for the <br />subject building will be identical to the 2008 drawings that NYA reviewed & approved <br />previously. <br />3. All building elements shall be redesigned as required to meet the CBC 2007 code <br />requirements. Among others, we list below a few of the important code changes that <br />may impact the subject building redesign: <br />a. It should be verified by the design team & the architectural plan reviewer if the code <br />changes triggers any occupancy category changes especially with respect to the <br />use of the two story atrium spaces at building entry or any other public assembly <br />type uses (the Building Importance factor, I, could go up). <br />b. The entire lateral force resisting system will need to redesigned & rechecked due to <br />the code change. In particular, for the 37-story tower this utilizes a dual structural <br />system - the R factors have been reduced in the new code. New/ different <br />redundancy checks, irregularity checks, modeling requirements, P-Delta checks, etc. <br />will need to be performed as part of the new lateral design. <br />c. Design needs to be updated for new code load combinations; Design of <br />discontinuous/ irregular elements for overstrength needs to include resistance <br />factors. <br />d. All concrete anchorage related items need to satisfy ACI 318-05 Appendix D <br />requirements. <br />e. All wind design related items will need to be redone per the new code requirements. <br />Wind load requirements are more involved & higher per the new code - especially for <br />roof elements & misc. parapets, canopies etc. <br />f. Steel SMRF elements & corresponding column bases/ anchorages need to be <br />designed per AISC 2005 Seismic Provisions. <br />g. Foundations need to be redesigned corresponding to new code forces & <br />requirements incorporating new findings on reduced punching shear capacity of <br />unreinforced concrete deep sections, etc <br />EXHIBIT 1 <br />1901-2
