Renovation of a museum in Brewster, New York. Completed plans call for the renovation of a 1,892-square-foot museum.

Reference Number 0000395790 Lightning protection system for Tilly Foster Farm Building #7 . The contractor shall provide all labor, materials, equipment, services, and incidentals shown, specified, and required to furnish and install lightning protection systems for buildings and structures as required by job conditionsfor a complete code compliant lightning rod protection and grounding system to protect the entire building from lightning strikes. The contractor shall design, install and certify the system for a two-story wood frame structure approximately 1,892 SF +/- known as Building # 7 - New Youth Bureau, located at Tilly Foster Farm, 100 Rte. 312, Brewster NY 10509 as shown on the attached Roof Plan and building photos. Time is of the essence for this project so all work must be completed no later than one week after issuance of Purchase Order. Question Acceptance Deadline 08/19/2025 12:00 PM EDT Questions are submitted online No . Questions should be directed to Alexis Hawley, Purchasing Dept: alexis.hawley@putnamcountyny.gov The lightning protection system shall include, but not limited to the following to: o Air Terminal Installation: o Air terminals shall be stainless steel 5/8-inch diameter and minimum of 18 inches long. Air terminalsshall include a cast bronze point protector,stainlesssteel adapter, and copper base. Provide air terminals at intervals not exceeding 20 feet along ridges and around perimeter of flat or gently-sloping roofs. Air terminals shall project a minimum of 10 inches above the area protected. Bond terminals to the conductor system. o Protect flat or gently-sloping roofs exceeding 50 feet in width, by providing additional air terminals at intervals not exceeding 50 feet on flat or gently-sloping area. Locate air terminals within two feet of roof edges and outside corners of protected areas. Air terminal spacing exceeding these dimensions will be allowed if the area protected is within a "zone of protection" from lightning strikes. o Provide air terminalsforstacks, flues, mechanical equipment, and other objects, having metal thickness less than 3/16-inch and not located within a "zone of protection". Connect objects having metal thickness 3/16-inch or greater to lightning protection system. o Do not connect copper equipment to aluminum surfaces, except using bimetal transition fitting. Lead coating is unacceptable for bimetal transition. o Install roof penetrations using through-roof assemblies with solid bars and appropriate roof flashing. Conductors shall not pass directly through roof. o Main Conductor Installation: o Install the main roof conductors along the roof's ridge(s). o Install main conductors to provide two-way path from each air terminal horizontally or downward to connections with ground terminals. o Grounded metal bodiesshall be bonded to the system using bonding connections and fittings. When ground conductors are installed in conduit, conduit shall be nonmetallic. o Install conductors free of excessive splices and sharp bends. Conductor bends shall form an included angle of not less than 90 degrees and shall not have bend radius less than eight inches. Secure conductors to structure at intervals not exceeding three feet. o Down Conductor Connection: o Install full-down conductors at intervals of up to 100 ft. around the building perimeter. Ensure connection to the grounding system below. Conceal down conductors where possible in exterior wall construction. Space down conductors at intervals averaging not more than 100 feet around perimeter of structure. Provide at least two down conductors for each protected structure. Chimney Air Terminal Installation: o Remove and re-install air terminals and bases spaced up to 20 ft. apart on the roof's chimney(s). Bond terminals to the conductor system. o Bond Connection to Water, Gas and Drainage: o Remove and re-install bonds to water, gas lines, drainage systems, and other components as required by code. o Bond building ground systems including electrical, communication, and telephone services and arresters. o Bond metal pipes and roof mounted metal structure to the roof ground loop or to downlead cables. o Provide ground electrodes for each down conductor dedicated for lightning protection system and bond electrodes to building or structure grounding system. Connect down conductor to ground rod using high-strength, removable ground clamp. Provide bronze ground rod clamp having at least 1.5 inches of contact between rod and conductor, measured parallel to the axis of the rod, at ground test wells.
