Geotechnical conditions play a crucial role in the proper construction of buildings, roads, runways, bridges, tunnels, and other structures. A solid foundation is an essential prerequisite for any well-constructed improvement. A thorough subsurface exploration can result in a more cost-effective foundation design and reduce construction delays caused by unforeseen conditions.
Big Apple has performed thousands of subsurface explorations on a wide variety of projects. Our experience ranges from projects requiring a few soil borings to large projects requiring several hundred boring and complete geotechnical recommendations. Our highly trained team of construction materials testing engineers and technicians are familiar with specifications from a broad range of agencies such as state and federal high departments, ASTM, AASTHO, NYCDOT, NYCDOB, NYCDEP, NYCHA, NYEDC, NYCMTA, SEPTA, NJTransit, PANYNJ, NJDOT, NJDEP, USACOE, DelDOT, PennDOT, USEPA, and many more.

Ground Penetrating Radar (GPR)
A Non-Destructive Testing method with unlimited applications that identifies inconsistencies within material. Ground Penetrating Radar does not require excavating, cutting, or removal of material. With this technology, Big Apple Group is able to assist with Utility locating to reduce the risk of utility damage during construction, structural analysis, determining the thickness of layers of asphalt, concrete, and many other materials.
GPR provides immediate results and reduces the likelihood of any unnecessary damage to existing structures. Discovering what lies beneath the surface, before coring, drilling, and evaluating while assisting in optimal planning and reduced liability.
Some of the various applications of Ground Penetrating Radar include the Analysis of Bridges, Towers, Tunnels, Balconies, Decks, Columns, Slabs, and Monuments.
