.r..� Northeast December 2,2013 I request that you grant a modification to waive the requirement for control construction for the project at 881 North King St. Northampton, Ma 01060 because the work is of a minor nature,will not affect health,accessibility, life and fire safety,or structural requirements and is impractical in that the cost of control construction is considerable when compared to the cost of the proposed work.((I have provided a stamped letter from a registered design professional which outlines the small amount of work to be performed on the existing roof structure,and states that the roof structure is adequate to support the additional load.))Thank you for your consideration. Respectfully, / t Phillip Baunsgard Jr. i MA-CSL#CS-106113 Installation Supervisor Northeast Solar Design (413)247-6045 136 Elm St. Hatfield, Ma 01038 Northeast'Solar Design,';136 E1m Street,Hatfield MA:01038•:413 247,6045 Vreeland Design Associates An integrative approach to design engineering and site planning Date: December 2, 2013 To: Ann Bronner NorthEast Solar 136 Elm Street Hatfield, MA 01038 From: David Vreeland, P.E. Vreeland Design Associates Re: Northampton Paint Center, 881 North King St,Northampton: Structural assessment of existing roof to support proposed solar array. On November 5, 2013, I conducted a site visit and investigated the existing roof framing in the area of the proposed PV panel installation. The existing roof trusses are installed at 7'-6" on- center, spanning 24', with 2x4 purlins on top of the trusses at 20" on-center and appear to be No 1 Douglas-fir. The top chord of the trusses are at a 4/12 pitch. I have reviewed the mounting details for the proposed array. Based on the specified PV panel unit weight of 42 Ibs, with the attachment points of the array installed along the first to purlins at the eave, and attached to 2x4 blocking installed between the first two purlins at the ridge, with the blocking attached to the purlins with joist hangers, and attached along the 3`d purlin down from the ridge, and then attached to the remaining purlins at 40" on-center and staggered to minimize the load to any one purlin. Install Simpson #H1 Hurricane Ties on the first two purlins at the ridge to reinforce the attachment of the purlin to the truss for uplift. Based on the above; the existing roof truss framing is adequate to support the proposed PV array. Please contact me if you have any questions or need additional information.
