Monmouth County, NJ


GTA performed a supplemental exploration to evaluate the extent of fill material across the location of a proposed 170,000-SF building and sports complex. GTA observed the excavation of shallow test pits across the site and performed Dilatometer Tests (DMT) at the approximate building corners. Using the soils’ strength and deformation properties from the DMT tests, GTA generated a refined soil profile for the site. GTA re-evaluated allowable bearing capacity and estimated settlement for the proposed structure in an attempt to optimize the foundation design. GTA provided a report summarizing the results and recommendations for design and construction of the proposed foundations and site improvements. The original engineer’s recommendation of undercutting the entire building pad would have added undue construction costs; however, GTA was able to provide significant cost-savings to the client by keeping the existing fill in place beneath the floor slab while only removing fill from beneath foundation footings and grade beams.

GTA also provided construction observation and testing services for the 170,000 SF building with a 90,000-SF indoor turf field and seven basketball courts on two levels, and associated infrastructure.
