Specialty Field Testing

Advanced Testing Solutions for Complex Site Conditions

Not all construction challenges are addressed by code-required inspections. Many demand advanced, field-adapted testing methods to diagnose unexpected issues, validate assumptions, or support engineering decisions in real-time.

AEIS’s Specialty Field Testing services provide clients with technically advanced, non-destructive, and minimally invasive testing methods that go beyond the standard inspection scope. These services are typically requested to investigate anomalies, verify as-built conditions, or support structural and geotechnical evaluations during construction.

While not mandated under the NYC Building Code, these tests are often critical to resolving disputes, mitigating risk, or guiding corrective work. Our engineers and certified technicians apply deep field experience and scientific rigor to ensure fast, accurate, and actionable results.

Common Specialty Testing Services Include:

  • Ground Penetrating Radar (GPR) – For locating rebar, post-tension cables, voids, and embedded utilities
  • Spectral Analysis of Surface Waves (SASW) – For profiling subsurface stiffness and evaluating soil-structure interaction
  • Impulse Echo & Ultrasonic Pulse Velocity – For flaw detection in concrete and estimating material uniformity
  • Rebound Hammer & Penetration Testing – For surface hardness and in-place concrete strength estimation
  • Half-Cell Potential and Resistivity – For corrosion potential assessment of embedded reinforcement
  • Infrared Thermography – For detecting delamination, moisture intrusion, or thermal irregularities
  • Windsor Probe & Pull-Out Testing – For in-place compressive strength assessment
  • Flatness/Levelness and Surface Tolerances – For slabs and critical structural surfaces
  • In-situ Moisture, pH, and Chloride Content – For concrete durability evaluations

These services are frequently used to address:

  • Unexpected subsurface conditions during excavation
  • Discrepancies between as-built and design drawings
  • Disputes over material quality or placement
  • Restoration or retrofit projects needing non-destructive verification
  • Owner-driven QA investigations for risk mitigation
  • AEIS: Field-Tested, Engineer-Backed

Our specialty testing services are supported by, certified NDT and materials testing technicians, and a deep understanding of construction performance standards. AEIS brings a solutions-driven mindset to every challenge, delivering fast turnaround and field-coordinated expertise helping your project stay on track.

Need clarity on what’s behind the wall, beneath the slab, or inside the structure? AEIS has you covered.
