Civil/site engineering and construction phase services for site development associated with the construction of a new student center. Services included design for access and parking, including pavement markings and signage, walkways and paths, fencing, drainage, stormwater management, water system, and gravity wastewater system. The stormwater management system was designed with subsurface retention chambers, infiltration chambers, and surface retention. Extensive retention facilities were required due to the limited capacity of the existing municipal storm system. Provided technical permitting of stormwater, water supply and wastewater disposal system, Act 250 Land Use Permit, and local approvals/permits.
Norwich University West Hall
Multidiscipline engineering services for West Hall the newest civilian residence hall on the Norwich campus. West Hall is similar to the successful South Hall civilian residence hall. D&K engineers also provided engineering and construction phase services for South Hall. Designed to accommodate 286 students, the $26 million West Hall dormitory is the second phase of a plan to create civilian housing that will eventually house 750 students and allow nearly all Norwich undergraduates to live on campus. Like South Hall, the 84,204-sf West Hall building features lounges, a game room, and facilities for exercise and laundry. It is designed to meet LEED certification guidelines for energy conservation.
DuBois & King provided site/civil, electrical, structural, and construction phase services for the 5-story, 286-bed, brick and steel framed structure with connections to municipal water and wastewater. Services included interior and exterior lighting, telecommunications design, landscape architecture, design of an infiltration percolation stormwater management system, survey, Act 250, and permitting.
Norwich University Student Housing Engineering and Permitting
Engineering services for two new Norwich University Student Housing (NUSH) projects. Services included site, survey, structural, and electrical engineering; landscape architecture; permitting; and construction administration for residential structures at the nation’s oldest military school. Both structures were designed to achieve LEED certification.
South Hall. LEED-Gold, $17.5-million, five-story brick building that houses up to 283 students and is the future benchmark for all new construction and renovation projects on campus. Services included civil/site design, permitting, topographic and boundary surveys, utilities, and cost estimates. Site improvements included grading, stormwater management system, access road/parking, pavement marking/signage, ADA accessible walkways/pedestrian paths, fencing, water system, and gravity wastewater system. Efficiency features include: design strategies to reduce water usage by over 30%; on-site stormwater management system provided water quality treatment, peak flow rate reduction, and groundwater recharge; site design minimized earthwork and reduced increases in new impervious area; and 427 tons of asphalt roadway leading to the dormitory was recycled/reused.
West Hall. Civil/site, electrical, and structural engineering, landscape architecture, survey, and permitting (including Act 250) services for a five-story, 286-bed, 75,000 sf brick and steel framed residential structure. Structural design drawings were produced in a BIM environment. Stormwater management was developed utilizing an infiltration percolation system.
Northern State Correctional Facility Mechanical System Upgrades
Design of energy efficiency measures to lower operating costs in six of the facility’s eight buildings totaling 156,000 sf. Renovated five variable air volume (VAV) heating/cooling systems including premium efficiency motors and variable speed drives. Secondary heating hot water loops were converted to variable flow with premium efficiency pump motors and variable speed drives. Control upgrades included a dual temperature comparison sequence to control the economizer mode for 23 air handling units, so that zones are not overcooled and require additional reheat capacity. Added control capacity to introduce demand control ventilation sequences for three air handling units. Variable air flow capacity was provided for the largest air handling unit.
North Williston Road Route 117 Scoping Study
On behalf of the Chittenden County Regional Planning Commission, D&K explored alternatives to improve the intersection of Route 117 and North Williston Road. In addition to traffic congestion, safety deficiencies, and bicycle/pedestrian mobility limitations, the area experiences repeated flooding and roadway over-topping between the Winooski River bridge and the Route 117 intersection.
Improvement options included signalization, signage, roadway realignment, and a roundabout. As it was determined that the area would flood repeatedly, easily operable gates with flashing lights were suggested for times when road closure becomes necessary. Services included:
Purpose and Need Statement
Right-of-way, utilities, and resource identification
Base mapping utilizing GIS
Topographic survey
Hydraulic condition and floodplain analysis
FEMA HEC-RAS modeling
Multimodal traffic forecasts
Public involvement meeting
Permitting (Act 250, CUD, and USACE)
Hydraulic and transportation alternatives/recommendations
