Testing and Inspection | Geotechnical and Geological Engineering

Materials Testing

Reinforcing steel
Prestressing tendon
Compressive strength - concrete, shotcrete cores, non-shrink grout cubes, CMU blocks, masonry grout, masonry mortar, masonry prism
Flexural strength - concrete
CMU unit weight, absorption
High strength bolts
Spray-applied fireproofing
Hot mix asphalt (Superpave); gyratory compaction, Hamburg wheel, tensile strength ratio
Hot mix asphalt (Hveem)
Hot mix asphalt extraction by ignition, bulk specific gravity, theoretical maximum density
Aggregate testing, e.g. sieve analysis, LA rattler, durability, soundness, organic impurities

Special Inspection

Reinforced concrete
Shotcrete/Gunite
Prestressed concrete (pre-tensioned and posttensioned)
Post-installed anchors, i.e. pull/torque, epoxy-set
Structural masonry
Structural steel high strength bolting
Structural steel welding (jobsite/field)
Structural steel welding (shop fabrication/source inspection)
Spray-applied fireproofing
Non-destructive testing (ultrasonic testing, magnetic particle, dye penetrant)
Horizontal wood diaphragm and wood shear wall construction
Hot mix asphalt
Coring of concrete & masonry
Moisture tests – concrete slab
