DCR Fleet EV Charging Stations Great Brook Farm Electrical Sketch.pdf

This is an electrical sketch document prepared for the Commonwealth of Massachusetts Department of Conservation and Resources (DCR) supporting a procurement for electric vehicle charging infrastructure at Great Brook Farm State Park in Carlisle, Massachusetts. The project involves the installation of two Level 2 dual-port networked pedestal-mounted charging stations (ChargePoint or approved equivalent), one 100-ampere electrical subpanel, charging station foundations, four bollards, disconnect switches, conduit, wiring, circuit breakers, and associated hardware at the park's Headquarters Building located at 984 Lowell Street. The electrical sketch provides the technical specifications and layout requirements necessary for vendors to understand the electrical infrastructure modifications required to support the charging stations. Mandatory site visits were scheduled for Tuesday, March 10, 2026, from 9:00 AM to 12:00 PM, with vendor questions due by March 16, 2026, at 9:30 AM EST and responses posted by March 19, 2026. Proposals must be submitted electronically through COMMBUYS by March 23, 2026, at 5:00 PM EST, with an estimated contract start date of March 30, 2026, and all work required to be completed by June 1, 2026.

This is a competitive sealed proposal procurement structured as a not-to-exceed fixed-price contract with itemized costs for equipment, labor, and services. The project is subject to the Small Business Purchasing Program (SBPP), which provides award preference to SBPP-registered participants meeting best value criteria, with non-SBPP bidders evaluated only if no SBPP participant meets evaluation standards. All contractors and subcontractors must comply with Massachusetts prevailing wage rates across over 150 construction classifications, with weekly payroll reports containing employee information and wages paid submitted directly to the awarding authority and maintained for three years. Vendors are responsible for all permitting, inspections, equipment commissioning, and work performed in accordance with the National Electrical Code and applicable codes. Coordination with DCR's trenching schedule is required, with approximately 3 days' work needed and 2 weeks' notice required, and vendors must coordinate with DCR regarding any archeological findings that may affect installation timelines. The specific contract budget or award value is not disclosed in the available procurement documents; however, the not-to-exceed fixed-price will be determined based on itemized vendor proposals submitted during the competitive evaluation process.
