Our work involves the testing and analysis of subsurface soil conditions including supervision of soil borings and/or test pits excavations; supervision of core drilling; examination of soil and rock samples in our laboratory; determination of depth to bedrock and water table; performance of field testing of soils; analysis of results; recommendations for bearing capacity and foundation design; and provision of specifications for supervision of controlled fill placement and footing construction. When problems arise during construction due to poor soil, groundwater, settlement, etc., we are often called in to determine the cause and prescribe the cure.

We are available to provide any or all of the following engineering services:
