To expand on-campus housing, NU needed a new 286-bed, five-story, 75,000-SF student housing facility. The project delivery method was unconventional, as the owner acted as the Construction Manager. D&K provided a range of services, including structural engineering. Structural systems consist of precast hollow core planks supported by structural steel beams and columns to facilitate low…
The Gray Farm needed a new waste storage facility and leachate collection system. D&K visited the site and conducted field survey and mapping, soil investigations, preliminary engineering, final design, and construction phase services while following the requirements of the NRCS EQIP program.
The North Attleboro National Fish Hatchery is a pond complex consisting of large rearing ponds supplied and drained by a network of water pipes and valves, which are equipped with concrete water control structures (called kettles) that control the pond water levels, manage the water between ponds, and drain the ponds. The USFWS required selective…
Located along the Konkapot River, the Berkshire National Fish Hatchery maintains lake trout brood stocks for restoration efforts in the Lower Great Lakes and raises brook trout for local recreation and educational programs throughout Berkshire County. The existing water supply system consisted of three shallow gravel wells and two springs that are connected, piped, and…
Sucker Brook was a deeply incised stream channel that threatened nearby infrastructure and sent an estimated one ton of phosphorus per year downstream toward Lake Champlain. The project goals included a reduction of sediment loading and erosion and the restoration of aquatic and riparian habitat while minimizing construction and maintenance costs. D&K prepared conceptual and…
Built into a hillside, Gardiner’s historic district, bounded by the Cobbosseecontee Stream and the Kennebec River, is garnering new interest and investment after mills and other large institutions closed. D&K developed a ten-year downtown master plan that improves resilience against coastal and inland flooding, economic sustainability, stormwater capacity and pollution control, and multimodal accessibility. Through…
The Chittenden County Regional Planning Commission and the City of South Burlington were interested in understanding how to improve pedestrian, cyclist, and vehicular safety and mobility at the Spear Street and Swift Street intersection. D&K provided analysis of the existing conditions, alternatives analysis, traffic modeling, intersection layouts in CAD, public engagement using an ArcGIS StoryMap…
The New Hampshire Department of Environmental Services identified the 1861 concrete and masonry Union Village Dam as high-hazard and deficient in a number of areas. The owners’ preferred option was to remove the dam to reduce potential hazards and remove a hydraulic and aquatic organism passage barrier from the river, restoring the river to a…
