Triad was responsible for all construction testing and inspections and also provided environmental consulting services for the T.C. Williams High School demolition/rebuild in Alexandria, Virginia.  This project was completed in phases so as not to interrupt the educational process.  The approximate construction cost for the project was $95,000,000.

Phase A-1 included demolition of a section of the existing building, installation of temporary classroom trailers, installation of storm sewer, modification to the parking lots and bus loop and construction of a retaining wall.

Phase A-2, the construction phase of the new building, included installation of intermediate foundation elements prior to shallow foundation construction.  Our scope of services also included inspections of concrete, masonry, reinforcement steel, foundations, subgrade, compaction of soils/aggregates/asphalt, structural steel, pre-slab inspections, and seismic monitoring associated with ground improvement operations.  Geotechnical elements included the installation of 1,770 rammed aggregate piers at the site.  Triad engineering technicians and certified weld inspectors served as an integral part of quality control during school construction.

Phase B-1 included moving from the old to the new building, demolition of the old building, and miscellaneous traffic and athletic field improvements.

The fourth and final phase, Phase B-2, included construction of a multi-level parking structure (in the location of the original building) and various traffic improvements.  T.C. Williams High School was completed under stringent constraints and was occupied on schedule for the 2007-2008 school year.  Also of note, T.C. Williams became the first K-12 school in Virginia to achieve a LEED gold certification by the U.S. Green Building Council.
