Sites with environmental issues have often been disturbed below grade or filled with non-native
material. In addition to identifying environmental contamination on such sites, it is important to understand the soils
and geologic properties with respect to future uses. SAI has its own geological/geotechnical staff prepared to address the
combined issues of soils, geology, and geotechnical engineering.
SAI offers Geotechnical Services for a wide variety of projects, including: multistory residential
and commercial buildings, schools, and garages; landfills; earth retaining structures; bridges; highway embankments; earth
dams; transmission towers; parking areas; and brownfields redevelopment.
SAI has provided geotechnical solutions to the following challenges:
- Building residential structures on a former landfill
- Developing specifications for construction of a school to be rebuilt on a contaminated site
- Designing a soil berm for an impoundment
- Evaluating landfill closure stability
- Conducting soil investigations for a major redevelopment area in Atlantic City
Our Range Of Sevices
- Preparation of subsurface investigation programs for drilling/installation of monitoring wells/piezometers
- Evaluation of design soil/rock parameters utilizing field data and laboratory rest results
- Design of earth retaining structures including sheet pile walls, braced excavation, mechanically stabilized earth
walls, and soldier piles and lagging
- Settlement analysis and design of different measures for reducing post-construction settlement including
preloading, wick drains and using light weight fill
- Design of rigid and flexible pavements
- Slope stability analysis
- Seepage analysis through dams
- Design of landfill closure systems
- Design of cutoff walls at landfill/contaminated sites, including slurry walls and deep soil mixing walls
- Veneer stability analysis of landfill liner and cover systems
- Design of methane gas ventilation/detection systems for buildings constructed over close landfills
- Design instrumentation programs for monitoring the construction activities and post construction behavior for road
embankments on soft soils and landfills
- Design of pond liners over steep slopes involving use of geosynthetic clay liners and geocells
In addition, SAI is home to a soil mechanics laboratory for testing the physical and mechanical
properties of soils. Testing capabilities include:
