SPECIAL INSPECTIONS (CMT)
We are proud to provide comprehensive special inspections and construction materials testing (CMT) to help ensure your project is built to specification, code, and best practices in accordance with the International Building Code. Our inspections support structural integrity, materials performance, safety, and long-term durability across a broad variety of projects in Pennsylvania, Maryland, New Jersey, and Delaware.
Our team offers an array of inspection and testing services including, but not limited to the following:
Fresh and hardened concrete testing (slump, compressive strength, air entrainment, temperature, etc.); non-destructive testing of existing concrete via rebound (Schmidt) hammer, ultrasonic pulse echo, penetrant testing, or other NDT methods; and destructive evaluations via Windsor Probe (ASTM C-803) and coring.
Site soil compaction testing (proctor, density, in situ tests via the nuclear method, ASTM D-6938), and subgrade inspection and validation prior to paving or structural slab placement.
Rebar placement review and tie/lap length verification; mortar and grout mix testing; and masonry unit inspections including grout flow and grout consolidation.
Shop and field visual weld inspection; high-strength bolting (preload verification, torque/tensioning checks); structural steel frame erection review; and NDT Testing & CWI (available upon request).
- Wall reinforcement, drainage verification, embedment, and anchoring; inspection of earth retaining structures, soil anchors, and foundation supports.
Thermal protection inspections on steel/structural elements including spray-applied and intumescent coatings; and firestop materials, joint penetration, and through-assembly penetration review.
Stone subgrade, base course, and paving compaction (ASTM D-2950) and thickness validation; stormwater infrastructure observation including confirmatory infiltration testing and trench backfill compaction.
With ICC- and ACI-certified accreditations, we are qualified to serve as an independent third-party inspection agency (TPIA) for commercial, institutional, residential, and specialty projects. We also provide limited NJ Special Inspectors and ICC Certified Inspectors for limited scopes upon request.
