First Baptist Church of Wilmington Activity Center, Phases I, II & III, Wilmington, NC

CTT provided full design services for Structural and Civil Engineering for Phase I, II & III additions to the FBC Activity Center Building, including all site permitting.  Phase I consisted of the design of a two-story, 21,000 SF addition against the front of the existing lower building.  Phase II consisted of a one-story, approximately 1,500 SF kitchen addition on the rear of the lower building.  Phase III consisted of a 15,650 SF gymnasium addition with stage against the northern side of the existing gymnasium and a single-story, 2,400 SF atrium vestibule addition.  A depressed stage was included in the activity center with a floor elevation and adjacent utility rooms approximately six feet below the outside ground elevation.

Civil site design included the design of the wet detention pond sized to treat runoff from the ultimate build out (Phase 3).  Design also included sole-design responsibility of the parking layout, site grading and utilities.  Parking layout included analysis to accommodate two large church buses through the parking lot and parking for the buses as well.  To keep the depressed stage dry, a foundation drain system was designed and installed around the building to drain into a wet well and pump.  The pump was designed with battery backup, so it will continue to operate during a power outage.  CTT coordinated with The City of Wilmington to incorporate a multi-use hike/bike path into the project.  The City will later connect it to the City-wide multi-use path.  CTT obtained approvals from City Technical Review Committee (TRC), City Water/Sewer, City Stormwater, State Stormwater, and County Erosion Control.
