The Hooksett Hydroelectric Project includes a 1.6 MW run-of-the-river hydroelectric power generation dam that is a barrier to aquatic organism passage (AOP), including Blueback Herring, American Eel, and American Shad. D&K worked closely with officials from the U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration regarding the details of the design,…
To support continued and upgraded use of its site for light industrial purposes, Chroma Tech needed to stabilize an adjacent slope. The aim of the project was to improve site stability and minimize erosion and stormwater pollution directly behind the facility. D&K evaluated the site and worked with regulators, the client, and a grant funding…
D&K provided mechanical, electrical, structural, landscape architecture, and civil design and retro-commissioning services for modifications of nine state facilities, converting from district steam to various types of local heating systems. D&K designed a new steam boiler plant—located remotely from the buildings it served—for the New Hampshire State House and two other State buildings. The project…
Located on the Otter Creek, the Huntington Falls Hydroelectric Project is a historic facility that required redevelopment. The D&K team assessed the two non-operational turbines and related appurtenances, the trash rack, and raker upgrades to the Unit 3 turbine following FERC relicensing. Additional D&K services included design and coordination to upgrade all three turbines, resulting…
The Neshobe River crosses through the heart of downtown Brandon, and the historic stone masonry bridge carrying Central Street/US 7 and numerous utilities had a history of substantially inadequate hydraulic capacity. As a demonstration of this issue, the town opened the front and rear doors of the adjacent town offices during a large storm event…
The City of Montpelier, in cooperation with the Federal Transit Authority and the Vermont Agency of Transportation, was redeveloping a brownfield site for a transit center, parking, and multiuse path on the banks of the Winooski River. The project required stabilization of a 135-ft-long by 27-ft-high section of river embankment. D&K provided geotechnical, civil, and…
Heavy rainfall and substantial snowmelt from a storm event combined with insufficient drainage systems to wash out 2,800 LF of a vital roadway crossing a mountain. The steep and winding road serves approximately 1,400 vehicles per day and connects VT 100 and VT 12. The Town of Rochester applied for and received FHWA-ER funding to…
Since their construction, Burlington’s largest parking garages had deteriorated, and the city’s operational requirements had evolved. The city also sought to reduce the frequent maintenance activities required to operate the facilities. D&K’s Resident Project Representative provided full-time construction observation and coordination with the city, design engineer, contractors, and subcontractors for improvements to two parking garages:…
Seeking a modernized and more capacious space for its administrative operations, the Taunton Municipal Airport advanced the construction of a 5,000-SF office building straddling a perimeter fence. D&K provided construction contract administration and observation and, as the Owner’s Project Manager, coordinated closely with the Contractor, Architect, Airport Operations, the Airport Commission, and the Massachusetts Department…
