Materials inspected as part of this project included:
Earthwork – Evaluating finished subgrades, monitoring the installation of deep foundation systems, and performing laboratory Proctor compaction tests and in-place field density tests.
Reinforced Concrete – Check reinforcing steel and placement; checking plastic concrete for temperature, slump and air content; and curing, weighing, and breaking concrete cylinders.
Masonry – Checking proportions of site prepared mortar, construction of mortar joints, and location of reinforcement and connectors; verifying size and location of structural elements; and monitoring grout placement.
Structural Steel – Verifying material of high strength bolts, nuts, and washers; verifying material of weld filler; verifying qualifications of shop and field welders; inspect welding of structural and reinforcing steel; inspecting steel frame joint details.
