The Construction Section consists of four laboratories that provide testing services on construction materials.

Physical Laboratory
Performs compression strength tests on concrete and masonry products. Tensile strength test are performed on steel products including reinforcing steel and pre-stressed cables. D-load tests are performed on both concrete and clay pipe. Sampling and testing is also conducted on PCC aggregate.

Special Materials and Research Laboratory
Tests miscellaneous construction materials including paint, rubber, plastic, coatings, sewer rehabilitation products, high strength bolts, metals, floor finishing materials, and sewer system liners. Non-destructive testing is also available for welds and construction materials.

Drilling Unit
Provides drilling, logging, and sampling services for subsurface investigation. Full laboratory support is available for testing soil engineering properties and possible chemical contamination. Other services include well installation and well abandonment.
