Our engineers have earned the trust of our clients by providing cost effective and practical design solutions for foundations.


Geotechnical & Geo-environmental Engineering is our core service and includes the following applications:

  • Site investigations;

  • Establishing the geotechnical criteria for foundation support and retrofit; 

  • Underpinning Design  

  • Design of Excavation Support Systems (sheet piling, soldier beam and lagging, diaphragm walls, secant pile walls) 

  • Geotechnical criteria for utility crossings beneath existing embankments or structures (Jack and Bore, Directional Drilling);

  • Dewatering during construction, and permanent underdrains;

  • Establishing the geotechnical design criteria for soft and hard ground tunneling;

  • Ground Improvement Design (Dynamic Compaction or Replacement, Preload, and surcharge, Design of Column Supported Embankment, Stone columns, stabilization with lime or cement, compaction grouting)

  • Geotechnical design of bulkheads;

  • Geotechnical Earthquake Engineering (Site Specific Response Spectra, Site Class, Assessment of Liquefaction Potential and Lateral Spreading);

  • Analyses of slope stability of cuts in soil and rock including soil nail and shotcrete stabilization design, and rock bolting design;

  • Value Engineering 

  • Geotechnical Instrumentation (Inclinometers, Piezometers, Earth pressure cells, Tilt meters, and crack gauges) 

  • Geotechnical observation (Inspection Services) for compliance with the criteria for site preparation, pile load tests, earth fills, and ground improvement designs. Oweis is a certified Class A inspection by NYCDOB.  

  • Expert reports and testimony related to post-construction performance 


Oweis’ geo-environmental services cover a range of services including:

  • Phase 1 Environmental Site Assessments.

  • Design of liners, caps, and containment soil-bentonite walls for sanitary landfills 

  • Limited environmental subsurface soil investigation in conjunction with a geotechnical investigation to evaluate the soil qualities for potential worker exposure, associated materials management during construction activities, and preliminary waste profile for off-site disposal.
