Portsmouth Seacoast Greenway Trailheads Design and Engineering

The City of Portsmouth Department of Public Works is soliciting proposals under RFP 01-27-RFP for professional engineering and design services to develop two trailhead facilities for the New Hampshire Seacoast Greenway. The project involves a 17.5-acre site at 445 Borthwick Avenue and a 7-acre site at 850 Banfield Road. The scope of work includes wetland flagging and surveys, engineering and drainage studies, conceptual and preliminary design, easement plans, environmental and cultural permitting, and the creation of final bidable plans and specifications. Planned amenities for the trailheads include paved parking, portable restroom enclosures, bicycle racks, horse trailer accommodations, kiosks, wayfinding signage, landscaping, and seating areas. This project is funded by a HUD grant, requiring strict adherence to HUD and NEPA regulations regarding procurement, reporting, documentation, and labor compliance. All final plans must be stamped by a Professional Engineer licensed in New Hampshire and provided in AutoCAD and PDF formats geo-referenced to NH State Plane Coordinates. Proposals are evaluated on a points-based system, with the highest weight placed on the qualifications of the firm and project team, followed by previous related work, responsiveness to requirements, understanding of the project schedule, and the proposed firm fixed fee. Bidable plans are expected to be completed by Spring 2027.
