Inspections Services

Certified inspections, testing, and compliance oversight for NYC projects—covering subsurface evaluations, special inspections, and materials testing from pre‑construction through closeout.

NYC DOB Special Inspections (TR1/TR8) & Testing | Audax NY

On-site inspections verify that concrete and masonry construction complies with approved plans, specifications, and applicable codes. Inspections focus on reinforcement, materials, workmanship, and curing to ensure safety, durability, and long-term performance.

Structural Testing

Structural testing evaluates in-place materials and assemblies to confirm strength, capacity, and performance. Results support design verification, renovations, forensic evaluations, and code compliance decisions.

Drilling & Sampling

Drilling and sampling provide direct information on subsurface conditions and existing structural elements. Collected samples are analyzed to support geotechnical evaluation, material verification, and reliable reporting.

Optical Monitoring

Optical monitoring tracks structural movement, settlement, and deformation with high precision. Data helps identify trends early and supports informed decisions during construction or adjacent work.

Vibration Monitoring

Vibration monitoring measures construction-induced ground and structural vibrations in real time. Monitoring helps protect nearby structures and provides defensible data for compliance and claims resolution.

Subsurface Investigation and Infrastructure Exploration

Subsurface investigations assess soil, groundwater, and underground infrastructure conditions. Findings support design planning, risk mitigation, and constructability decisions.
