Field Testing

Accurate data from crews who know construction sequencing.

Our technicians partner with superintendents and inspectors to align on acceptance criteria before arriving on site. The result—fewer re-tests and data you can trust the first time.

  • Certified technicians across earthwork, concrete, asphalt, fireproofing, and structural steel.
  • Connected instrumentation delivering telemetry to dashboards for immediate review.
  • Mobile reporting apps streamline photos, signatures, and daily field logs.
Lab Testing

State-of-the-art laboratories engineered for throughput.

From soil classification to concrete and asphalt performance testing, our labs are calibrated to ASTM, AASHTO, and project-specific standards with rigorous QA/QC protocols.

  • Automated sample tracking that links chain-of-custody to each test result.
  • Dedicated curing rooms and climate-controlled storage for reliable strength data.
  • Specialty triaxial, permeability, and consolidation testing delivered on aggressive schedules.

Reporting

Fast, detailed narratives that keep projects aligned.

Every result is delivered with context—field notes, photos, and specification references—so teams can approve pours, paving, or backfill without delay.

  • Automated distribution lists ensure stakeholders receive updates the moment they publish.
  • Interactive dashboards for trend analysis, non-conformance tracking, and documentation downloads.
  • Integrated client portal with secure historical archives and search-ready reports.
