The Northfield Common had long served as a focal point of the community and a center for gatherings, passive recreation, and events, such as a farmer’s market. The town sought to enhance the space for current and anticipated uses. Through a robust engagement program, D&K worked with town officials, public community members, and abutters to…
The transmission line owner required updated condition information on the foundation and structural support members of 165 high-tension lattice electrical transmission towers. D&K’s structural engineers visited each tower along the entire length of the project, often in remote locations with challenging terrain and access. We used a cloud-based assessment system to allow office personnel to…
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:…
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…
To develop a safer and dedicated cyclist and pedestrian-focused path from downtown to Gallison Hill Road, the City of Montpelier chose to develop a paved, largely off-street pathway, which shared a substantial portion of its alignment with a local railroad. Weaving through a largely urban area, the project creates an active transportation and recreation right…
Burlington was awarded Silver status by the League of American Bicyclists, and the city was interested in “going for Gold.” The city sought to upgrade connectivity and bike/ped facilities to welcome additional cycling demographics that may be interested in cycling, but are intimidated by the speed and proximity of existing vehicle traffic. D&K served as…
