Geotechnical Field Investigation
Geotech consulting plays a crucial role in the proper construction of buildings, roads, runways, bridges, tunnels, and other structures. A geotechnical survey also known as a geo tech survey, is an essential prerequisite for any well-constructed improvement. Thorough geotechnical soil testing and ground investigation can result in a more cost-effective foundation design and reduce construction delays caused by unforeseen conditions.
Big Apple Group maintains a large variety of land and marine subsurface exploration equipment, along with laboratory and office facilities that allow for a variety of material testing and inspection solutions including but not limited to compaction testing and pull testing. We have multiple fully equipped exploration crews with drill rigs mounted on all types of carriers to allow access to virtually any condition on land or water.
As geotechnical consultants, Big Apple has performed thousands of geotechnical drilling surveys on a wide variety of projects. Our experience ranges from projects requiring a few geotechnical borings to large projects requiring several hundred geotech borings also known as soil borings and provide 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)

Non destructive testing of concrete identifies inconsistencies within material. To complete a non-destructive inspection, Big Apple Group uses a Ground Penetrating Radar System which does not require excavating, cutting, or removal of material. With this (GPR) ground penetrating radar, 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 scanning 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 services include the Analysis of Bridges, Towers, Tunnels, Balconies, Decks, Columns, Slabs, and Monuments.
