This massive eleven (11) building master planned campus for the US Navy consisted of more than 669,206 SF of building footprints and more than 734,000 SF of parking. The project, which provided residential barracks buildings, telex buildings, and an LMCC facility, was valued at more than $195M.
The infrastructure needs for the campus were all-encompassing and complex. Overall, the site required 6200 LF of roadway (Birch, Cross, and River Roads), 8700 LF of dual 16” sanitary sewer forcemain, 4300 LF of 12” water main, 2800 LF of additional forcemain, a sanitary lift station, 11,800 LF trail system, and a water booster pump station. The project also included a 500,000 gallon water tank, a booster station, a 300 gallon chlorine tank and injection system, several miles of watermain, and hydrants, valves, and appurtenances.
The traffic elements for this project required Calibre and our staff to analyze multiple intersections and determine control measures, pedestrian interface, and lane requirements, including one traffic signal with detection, radio communication, and future allowances.
The project required pulling more than 20 permits, including NCDENR/DWQ, NCDENR/LQS, NCDENR/PWS, 404, 401.
The earthwork and grading was extensive and moved more than 300,000 cubic yards of material.
Because the site was adjacent to Natural Waters of the US, Calibre designed grading solutions to protect the natural waters from the earthwork operations. Our design included grass-lined swales, which were crafted by shaping the grades during earthwork operations to create conveyance elements with stormwater management benefits.
We provided designs for wetlands crossings of roadway and/or greenway trails at three separate locations for the project. Wetlands avoidance, impact minimization, and permitting played important roles in the design of these elements.
The site incorporates the following LID design processes to diminish water pollution and facilitate on-site infiltration:
- Incorporating grassed swales throughout the site to slow runoff and facilities infiltration
- Disconnecting paved areas where possible to allow runoff to be conveyed over pervious areas instead
- Minimize the use of curb and gutter where possible
Additional sustainable design elements included recycled materials, low VOC content, passive solar design concepts, geothermal heating, ventilating, and air-conditioning system, grass-lined channels, retention basins to reduce impervious cover, increase on-site infiltration, and geothermal wells (198).
Calibre provided design features to reduce or eliminate water pollution, and the buildings included spectrally-selective window glazing allowing illuminating light to enter interiors while blocking heat gain rays, incorporated sanctioned lumber products to maintain forests elsewhere onsite, included solar panels transfer heat to water storage tank, and attained American Society of Heating, Refrigerating, and Air Conditioning energy reduction goals.
The very rapid schedule, which required the bulk of a $1,000,000 engineering design to be completed in less than 6 months, was met without a hitch. We value engineered a major drainage crossing to reduce the cost of the pre-construction estimate by 1/3.
