About this file
Summary
This document is a set of bid-level engineering drawings prepared by Turner Engineering, PC for the Town of Portage's Town Hall Renovation project located at 9907 Church Street in Hunt, New York. The drawings specify the design and installation requirements for a geothermal heating and cooling system as part of a comprehensive net zero energy renovation that includes full interior renovation, new offices, and all new utilities (plumbing, HVAC, and electrical). The geothermal system design includes a vertical bore hole loop field extending 600 feet deep with 1.5-inch IPS HDPE piping, horizontal loop field trenches with manifold assemblies, and associated piping details for connection to the mechanical room. The project may incorporate either the specified geothermal heating and cooling system or an alternative natural gas heating and cooling system, with a solar array system also included subject to potential downsizing per town request.
The drawings provided (sheets LF-100 and LF-200) represent the detailed technical specifications for the geothermal loop field installation, including bore hole details, horizontal piping trench configurations, floor penetrations, valved manifold assemblies, and return header details. All work must be performed under the direction of licensed professional engineers, with specific requirements for thermal enhanced grout, detectable tape placement, sand bedding, and backfill restoration. No specific bid due dates, pricing terms, set-asides, incumbent information, or funding source details are included in these engineering drawings, which serve as supporting technical documentation for the overall town hall renovation procurement.
