Renaissance Geotechnical Engineering, PLLC is managed and operated by a NY, OK, TX, MD, and RI registered Professional Engineer with a master’s in civil engineering and a geotechnical focus. The firm’s competencies include providing expert level, cost-effective subsurface investigation and geotechnical evaluation of soils and rocks for shallow and deep foundation design as well as pavement analysis and design. Other competencies include slope stability and settlement analyses of embankments, dam safety investigation, special inspections and construction material testing, construction administration and value engineering. Renaissance Geotechnical also has expertise in pavement management and pavement design through the use of non-destructive and destructive testing such as the falling weight deflectometer (FWD), the ground penetrating radar (GPR), the dynamic cone penetrometer (DCP), and the light weight deflectometer (LWD).
