Blackwood-Clementon Road

The Boroughs of Lindenwold and Pine Hill New Jersey planned the construction of a new road and the replacement of two existing bridges along Blackwood-Clementon Road.  ACER performed a subsurface investigation in the area of the proposed road and bridges including...

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:










Atterberg Limits

California Bearing Ratio


Direct shear

Electrical resistivity


Hydraulic conductivity


Moisture content




Soil density

Triaxial (UU, CU, CD) shear tests

Unconfined compression

Geotechnical Engineering Reports:

Based on the results of the subsurface investigation and the laboratory testing program, ACER performs an engineering analysis of the subsurface soils and/or bedrock. ACER then prepares a final Geotechnical Investigation Report, which summarizes the subsurface investigation, on-site soil strength conditions, and gives recommendations regarding foundation design and general foundation installation criteria.


ACER employs an experienced staff of Professional Geologists, Professional Engineers, and Hydrogeologists capable of handling the complexities of any project.  Furthermore, ACER has an extensive network of qualified laboratories and drilling and excavating companies, allowing us to provide these quality services at reasonable costs.
