Site Investigations
Built on a century of experience in the foundation construction industry,
Subsurface Constructors maintains a large database of the region’s geology.
Our knowledge of the strata most likely to be encountered on a project
allows us to be a valued foundation consultant during pre-project planning.
In addition, we have truck, ATV and skid-mounted test drilling equipment
that can be used to verify existing geotechnical data, as well as provide a
means for collecting additional soils and rock information.
Foundation Load Testing and Shoring Instrumentation
Subsurface Constructors possesses the engineering expertise and necessary
equipment to perform geotechnical load testing methods. We have completed
thousands of load tests on micropile, augercast pile, driven pile, drilled
shafts, and vibro stone columns, verifying design loads or proving higher
capacities that allow for a reduced number of foundation elements.
On a recent project, we used an
Osterberg Load Cell test to demonstrate that
drilled shafts could withstand a much greater load than the original design
load. The number of drilled shafts on the project was significantly reduced,
resulting in an overall project savings of over 30 percent. This testing
capability clearly allows us to present significant value engineering
alternatives.
On large earth retention projects, quality construction is the top priority,
but services are not complete when our equipment leaves the worksite.
Utilizing our experience and instrumentation, we can continually monitor the
movement of large earth retention systems after we have finished building
them.
