About this file
This file contains engineering drawings and technical specifications for a Town of Portage town hall renovation project that includes the design and installation of solar photovoltaic and geothermal heating and cooling systems. The project is located at 9907 Church Street, Hunt, New York 14846 (coordinates 42.54, -77.99), and is designed by Turner Engineering, PC and Hager Engineering Solutions. The solar system design specifies 72 Longi LR5-72HBD-550M bifacial solar modules (550 watts each) totaling 39.6 kilowatts DC rated capacity, with three SolarEdge SE11400H-US inverters (11.4 kVA each) providing 34.2 kilowatts AC rated capacity. The system includes a 225-amp service panel, PV combiner panel, fused disconnect, and 36 SolarEdge P1100 optimizers configured as two modules per optimizer across two strings per inverter with 12 modules per string. The estimated annual production is 50.8 megawatt-hours with 47 megawatt-hours of annual export and a 543 percent utilization rate. The geothermal system design includes vertical bore holes 200 feet deep with 20-foot spacing between bores (or alternatively one 600-foot bore if geology permits), utilizing 1.5-inch HDPE piping in a closed-loop configuration with thermal-enhanced grout and flowable fill specifications. All work must comply with NEC 2017 standards and industry specifications as detailed in the four attached sheets (E-201, E-202, LF-100, and LF-200), which were issued on August 29, 2025, with general revisions dated December 1, 2025.
The bid documents do not specify pricing terms, contract values, specific response deadlines, or award dates within the engineering drawings provided. The project description indicates that the solar array construction and installation may be subject to downsizing per town request, and contractors may propose either the specified geothermal system or an alternative natural gas heating and cooling system. No business enterprises have been awarded identical or substantially similar procurement contracts within the past five years. All equipment must be UL-listed for use in the specified system configuration, and all conductors and equipment shall be labeled per NEC standards. The project represents a net-zero energy building design incorporating comprehensive mechanical, electrical, and renewable energy systems.
