Colgan, Sr. High School & Aquatic Facility Charles J Colgan, Sr. High School and Aquatic Facility, Manassas, Prince William County, VA This 371,381 SF high school was a $98 million project and consisted of a one and two-story building with structural steel and load-bearing masonry walls, supported by conventional shallow foundations with on-grade slabs. Known as Prince William County’s Center of Fine and Performing Arts, the construction necessitated a special Amphitheatre which included an expanded auditorium and orchestra pit. Furthermore, the school features a 30,000 SF aquatic facility with a competition-sized main pool and a companion instructional pool for swim practice and underwater robotics. The aquatics center is also opened on the weekends to the public. Among the separate structures supporting the school are a concession building, drivers training building, outbuilding, and ticket booth. Multiple competition and practice fields for football, baseball, and softball were constructed for this project along with tennis courts and an outdoor basketball court. In addition, the site includes large amounts of parking for both school busses and cars, along with three storm water management ponds. During WDP’s geotechnical investigation, it was discovered the site contained large amounts of Elastic SILT (MH) soil both in the proposed building pad and in cut areas. Based on recommendations from WDP, the project was bid unclassified with requirements for undercut of MH soils to suitable depths which provided the school system with no costs for the undercut and meant that they did not have to worry about expensive change orders during construction. Besides providing geotechnical engineering services, WDP also provided special inspections and materials testing services which included: 5 Gravity retaining walls 8 to 15 ft. in height: foundations, drainage, structural fill and masonry School structure: structural fill, soils and foundations, cast-in-place concrete, reinforcing steel, masonry construction, and structural steel VDOT right-of-way lane: laboratory testing of soils, testing of concrete and asphalt.
