QA and QC – Construction Company

Independent pile testing and quality assurance that removes doubt and protects your investment

We provide science driven, design ready verification for foundations and structural elements so engineers, contractors and owners can build with confidence.

Whether it is a high rise, bridge, port terminal or industrial complex, our role is clear:

We verify that foundations and materials meet the highest international standards before the superstructure takes shape.

Precision services that reduce risk

We deliver practical, technically rigorous testing so you get reliable answers fast. Our core capabilities include:

Low strain integrity testing to detect cracks, voids, necking or bulging and to confirm pile length and cross sectional consistency without damaging the structure.

The benchmark test for pile capacity. We apply controlled loads in compression, tension or lateral modes and record displacements to establish ultimate bearing capacity and validate design assumptions.

Real time measurement of force, velocity and energy during pile driving or re striking to evaluate pile performance quickly and cost effectively, with correlation to static results where required.

High accuracy verification for drilled shafts and bored piles using ultrasonic probes in access tubes to locate voids, honeycombing or inclusions. Essential for critical infrastructure projects.

Ultrasonic pulse velocity, rebound hammer and other NDT techniques to assess concrete and structural elements for hidden flaws while preserving material integrity.
