Geotechnical Engineering Specialties
Comprehensive Subsurface Exploration & Testing
We provide thorough, state-compliant site investigations designed for accuracy and regulatory compliance. Our services include test borings, test pits, infiltration testing aligned with State and NYCDEP Green Infrastructure standards, karst investigations, and laboratory testing of soil and rock properties. Electrical Resistivity Testing (ERT) further maps subsurface conditions for deeper insight.
Foundation Design & Expert Recommendations
From shallow spread footings and mat foundations to advanced deep foundation solutions like driven piles, micropiles, caissons, helical piles, and drilled shafts — we deliver tailored foundation designs that provide maximum support and stability.
Advanced Geophysical Surveys
Using non-invasive technologies, we enhance subsurface data while minimizing risk and disruption. Our in-house geophysical surveys include:
- Ground Penetrating Radar (GPR) to detect underground utilities, voids, and material changes
- Electrical Resistivity Tomography (ERT) for detailed subsurface layering and water table mapping
- Multichannel Analysis of Surface Waves (MASW) to profile seismic velocity for site classification and soil stiffness
Retaining Wall & Earth Retention Solutions
Whether you need sheet pile walls, soldier piles, gravity walls, or mechanically stabilized earth walls, ANS designs retaining systems that secure your site and protect your structures. We also specialize in support of excavation designs to keep your project safe and on track.
Earthwork & Site Development Expertise
From soil stabilization and excavation to grading and site restoration, we provide comprehensive earthwork analysis and recommendations. Our expertise includes embankment design, settlement control, compaction monitoring, and ensuring solid groundwork for lasting performance.
Geotechnical Construction Inspection
Geotechnical construction inspections, including deep foundation testing, earthwork compaction, slope inspections, retaining wall monitoring, and excavation support systems. We maintain strict adherence to project specifications and industry standards to keep your construction on track.
Specialized Geotechnical Consulting
We offer expert forensic investigations to diagnose site or structural issues, along with comprehensive slope stability analyses and seismic risk assessments to enhance safety and resilience. Additionally, our team provides pavement analysis and design services to ensure durable, long-lasting surfaces tailored to your project needs.
What clients are saying
"We have worked with the ANS team on several projects around the country and have had a great experience on every occasion. The team’s attention to detail is impressive and the daily reports provided contain the right amount of information about survey updates. The team is proactive and have on several occasions highlighted areas of concern once identified. Upon delivery of geotechnical reports, the team spent time going over the results and implications with us and discussing next steps and key things to look out for during future development."
Adenike Thompson
“ANS does a great job providing daily updates when working on a project and breaking down key points. I continue to seek them out for geotechnical work on my projects.”
Meg Witte
"Working with ANS was an absolute pleasure. Their expertise, dedication and commitment to excellence made our project not only successful but also enjoyable. I look forward to working with them again and highly recommend their services to anyone seeking a reliable geotechnical partner."
