<br /> <br /> <br /> <br /> <br /> <br /> <br /> REQUEST FOR PROPOSAL <br /> STRUCTURAL PLAN CHECK SERVICES <br /> 1001 NORTH BROADWAY PROJECT <br /> SCOPE OF WORK <br /> <br /> <br /> 1. 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 /> <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 /> <br /> <br /> <br /> EXHIBIT 1 <br /> <br /> <br /> <br /> <br /> <br /> 1901-2 <br />
