Approximately 400 LF of the Town Highway 35 (Gilman Road) embankment along the White River failed as a result of flooding following a severe storm. The vertical height of the failed riverbank is approximately 80 ft. The road embankment was eroded, and the resulting slope was unstable and vulnerable to damage. On behalf of the…
The Guilford Central Village offers an extensive set of amenities within walking distance of one another but the only connection is a 22-ft-wide roadway that must accommodate all travelers, including cars, buses, trucks, bicycles, parents, and children. D&K worked with the town to develop a scoping study to create a safe walking route along Guilford…
Travel speeds in the village were a concern for the wide variety of modes and users in the area, including commuters, logging vehicles, maple sugaring equipment/vehicles, visitors, pedestrians, and bicyclists. D&K visited the village to understand existing conditions while considering potential constraints and opportunities for traffic calming measures and crosswalks. Our project team reviewed on-street…
The City of Lebanon needed to replace a functionally obsolete crossing with inadequate geometry that was at the end of its service life. The three-span, 145-ft-span steel stringer bridge that crosses over the New Hampshire Railroad serves NH 12A at a skew with the railroad tracks immediately adjacent to the congested intersection with US 4….
The Town of Royalton secured FEMA funds to replace a culvert that had been undermined by a large storm event. DuBois & King designed a 12-ft-wide by 7-ft-tall metal arch plate culvert that was sized to accommodate large, native boulders to attenuate flows and provide eddies for fish to rest in while traveling up the…
To serve existing users and a projected increase in operations, the Machias Valley Airport needed to upgrade its fuel farm. Under an on-call contract for airport engineering, D&K worked with the airport to design and support the construction of an AVGAS/100LL fuel farm, including a supplemental survey, structural considerations for a concrete slab to support…
The City of Burlington wished to enhance bicycle connectivity along Colchester Avenue, which crosses the University of Vermont education and medical center campuses. The project area was heavily used by vehicles, bicycles, and pedestrians, and the city wanted to alleviate congestion by constructing an off-street, 2,150-ft-long by 10-ft-wide concrete multiuse path to provide an active…
The Addison Town Hall and Addison Community Baptist Church needed a centralized wastewater system to reestablish use of the historic Town Hall building, which sat vacant for nearly a decade. The structure required significant renovation, and its marginal (mostly clay) soils and a high water table made a conventional on-site wastewater system infeasible. At the…
The existing circa-1927 water lines were deteriorating and in need of replacement due to frequent leaks and need for emergency repairs. D&K provided design, permitting, bid, and construction phase services to replace 3,083 ft of water lines, hydrants, valves, and metering as part of a 9,110-LF distribution system. Construction of the water distribution system was…
