Field Investigations:

These geotechnical investigations include subsurface field investigations, laboratory testing, and geotechnical engineering analyses. ACER's subsurface investigations define the stratification of the subsurface soils and the engineering properties of these soils across the proposed construction area.  ACER uses its extensive knowledge of local geology to prepare these subsurface investigations in a cost-effective and efficient manner.  ACER employees oversee the subsurface investigations, which are conducted through the completion of test borings or test pits excavated by one of ACER's competent, professional drilling or excavating subcontractors.  These test borings and pits provide ACER with the information necessary for proper evaluation of the subsurface soils at the site.  ACER's direct oversight of each subsurface investigation allows for quick, efficient changes in the investigation plan, should the need arise.

As part of the geotechnical investigation, ACER's laboratory-testing program is tailored to the soils and /or rock found at each site.  This enables our geotechnical team to fully define the physical characteristics of the subsurface materials encountered during the subsurface investigation. Soil testing may include any of the following analyses:
