The purpose of this review was to provide an opinion as to the structure's ability to support 372 West Street proposed rooftop photovoltaic panels. You also provided catalog information on the St/lteloo proposed photovoltaic (PV) panels. Both the roof structure information and the information Keene,NH03431 on the proposed PV panels are attached to this letter for reference. T:603.283.0300 F 603.283.0301 You are proposing to erect PV panels on the southeast side of the roof of the former pool www.gza.com house.The structure is a single story building measuring approximately 28'x35'.The building has a gable roof which is symmetric about the peak. The roof pitch is 35-degrees. The roof has 2x8 rafters at 16" O.C.These rafters have ties near the peak and ceiling joists between the peak and eaves. 2x4 vertical supports run between the ceiling joists and peak. 1x8 diagonals run from the ceiling joists to the rafters.The rafters run 16.5' on the horizontal. You report that previous renovation efforts were undertaken to remove the pool and convert the building to living space.The work was not completed and the walls and ceiling remain unfinished at this time. The presence of wire cables with turnbuckles, which run between walls, perpendicular to the peak, suggest that the walls had previously begun to move outward due to the end reaction of the rafters at the top of the walls. Since the ceiling joists are above the bottom of the rafters, it is likely they did not restrain the outward end reaction of the rafters. During the renovation efforts, support beams of 4-ply 2x12s were added. These beams run parallel the peak and support the rafters where the rafters and ceiling joists connect. These beams are supported by wood columns at regular intervals. Metal connectors join the columns to beams. The roof deck is plywood, and the roofing material consists of asphalt shingles. M Equal Opportunity Employer M/F/V/H Janurary 18, 2017 GFile No. 02.0172356.10 T-5 Weinberg Residence, Northampton, MA Page 12 Discussion: It is likely that the installation of the beams at the rafter-ceiling joist connection has relieved the rafter system of most of the outward horizontal end reaction at the walls. Still, the lateral restraints are beyond the scope of our review. As such, GZA offers no opinion as to the advisability of removing the lateral wire tension ties. Further, it is unclear if the posts which support the beams have been built on a proper footing.We provide no opinion as to the adequacy of the post/column foundations. Conclusion: Based on the information and photographs you have provided, in our opinion, the roof is satisfactorily robust to support the additional dead load of the proposed PV system. We base this opinion on the information you have provided and the following assumptions. We assume that, owing to their slippery surface,the solar panels will shed snow better than the asphalt shingles.We further assume that the panels will be installed parallel to the roof, eliminating any additional wind load. The design ground snow load for Northampton is 55 psf. Based on the information you provided the proposed PV panels weigh 2.6 psf(4.7%of the design ground snow load). To summarize, in our opinion, the roof is structurally adequate to support the additional Dead Load of the proposed roof mounted Photovoltaic System. If we can be of further assistance, please call Jonathan Rugg(603) 232-8794 or Carl, Goldknopf(603)232-8792. Very truly yours, GZA GEOENVIRONMENTAL, INC. ,a;14(1:44- C1/7/e/.11.Jonathan Rugg, P.r.
