Stormwater design and permitting assistance was required for the widening and upgrade of approximately one mile of roadway near the intersections of Routes 7, 2A, and 127. The project entailed widening, overlay, and reconstruction, as well as new curbing, drainage, bike lanes, signals, and signage. D&K provided drainage design, hydrologic analysis of stormwater runoff rates…
The Charlestown drainage system consisted of 20 catchbasins, manholes, and approximately 3,700 feet of stormwater conveyance pipe, which collected stormwater from approximately 20 acres of pervious and impervious surfaces. D&K evaluated the stormwater collection and conveyance system due to observed system failures, such as stormwater being discharged from the system through inlets rather than the…
The roadway/stormwater component of the Cabot-Danville US 2 safety project consisted of the reconstruction of three segments totaling 4.25 miles. D&K developed stormwater treatment and control to minimize right-of-way impacts and provided planning, design, and permitting assistance.
The National Life of Vermont campus had stormwater conveyance and discharge systems that flow over steep banks and connect into the municipal system on Memorial Drive. Over time, flow through a section of the corrugated metal pipe began to leak at the joints causing erosion around and undermining of the pipe. D&K evaluated existing conditions,…
To provide wide-ranging, reliable, and high-capacity coverage, Verizon Wireless renovates its facilities, establishes new sites, and constructs telecommunication installations on existing, prominent structures. D&K has served more than 200 of Verizon’s locations throughout Vermont. These sites range from locations in buildings, on farm silos, and at other urban locations to remote rural, mountain, and wooded…
D&K provides civil, structural, mechanical, water resource, dam, environmental, and geotechnical engineering and permitting assistance to support maintenance and upgrades to a Northeast-focused hydroelectric utility. Project types include penstock inspections, power generation and project redevelopment studies, new fish passage systems, fish passage system maintenance, FERC licensing support services, permitting assistance, survey, substation and lattice structure…
To address conditions posed by environmental changes, infrastructure service life and suitability, shifting power production, and consumer use trends, Vermont Electric Coop regularly improves its substation yards and transmission infrastructure. Under an on-call arrangement, D&K provided survey, civil, and structural engineering to more than ten locations throughout VEC’s service area.
Green Mountain Power (GMP) is a private electrical utility provider that maintains much of Vermont’s electrical distribution and hydroelectric power-generating infrastructure, solar farms, and natural gas cogeneration facilities. As GMP has grown through expansions and small utility provider acquisitions over the past 20 years, D&K has supported approximately 200 projects, and we continue to provide…
This fast-track project included collecting the location (within 0.06 ft) of approximately 1,535 water gate valve locations for the city’s GIS database and future projects. Working closely with the city and in coordination with ongoing roadway construction activities, D&K staff collected water gate valve locations using survey-grade GPS units tied into the Vermont CORS network….
