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…
D&K provided design-build renovations on this 9,000-SF fire station. Upgrades included administrative offices, a training room, and a high-bay apparatus area for eight emergency vehicles. Our civil/site team provided permit work and applications, building surveys, grade development, stormwater management, driveway and parking areas, ADA-accessible walkways, and three 14,000-gallon buried water storage tanks for emergency vehicle…
Located on 4.5 acres in Randolph Village, Salisbury Square is an affordable and sustainable housing development that includes three four-unit, low- and median-income apartment buildings. The development also includes an office building and space for the addition of up to nine single-family homes. D&K provided survey and civil engineering and D&K’s electrical engineers designed the…
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…
Two dams in a park owned by a community association were damaged by storm flows. The lower dam was breached and required design alternatives for its removal; the upper dam had to be evaluated for repairs. D&K reviewed the structural elements of both dams, the retaining wall, and the stream character upstream and downstream. Our…
The 40-year-old wastewater treatment facility, originally designed for a 20-year service life, was past due for a total treatment process change and facility upgrade. The project objectives included: utilize a state-of-the-art treatment process, design capacity for nitrogen removal, consider operational efficiencies and long-term operating costs, address issues with the location in a floodplain, and develop…
To efficiently manage the design of highway surfacing and appurtenant systems, the Vermont Agency of Transportation (VTrans) engages consultants to supplement in-house engineering, environmental, and surveying services. Since 1998, D&K has provided design for state and US highways, including interstates, urban Class 1 sections of US or state highways, major and minor arterials, and rural…
