Specifications include, but are not limited to: Earthwork under Building (Specification Sections – 014000, 312316.13, 312323) Earthwork testing and inspection under the building and 10 feet beyond the perimeter will be as outlined in Structural Fill Specification Sections. This work will require full-time/parttime inspection based on the building code. A proposed structural fill sample will be obtained, and the required laboratory tests will be performed. Proper depth of cut will be verified, stripped subgrades will be examined by means of proofrolling, and an appropriate quantity of density tests on structural fill will be performed. Specified equipment and compaction procedures will be verified. Foundations (Specification Sections 014000, 031000, 032000, 033000 and Structural Drawings) The foundation system for this project will be spread footings. Inspection during foundation placement will be full-time/ part-time per the building code. Before concrete placement, the foundation bearing area of the spread footings will be verified for the required bearing capacity. The reinforcing steel will be verified according to what is listed in the "Reinforcing Steel" section below. Dowel size, spacing, and projected lap splice length will be verified. The appropriate concrete tests as outlined below will be performed. Normal Weight Concrete (Specification Sections 014000, 033000) Tests on fresh concrete, as listed in the specifications, along with cylinders will be taken for every 75 cubic yards of concrete. Four cylinders per set will be required for compressive strength tests. Any 7-day compressive strength test that breaks less than 70 percent of the design strength and any 28-day compressive strength test that breaks less than the design strength will be reported by telephone. The contractor may mold cylinders, as an economic consideration, when authorized by the Structural Engineer. The Testing Agency will furnish equipment for performing slump tests and cylinder molds for compressive strength tests. The Testing Agency will verify that the Contractor is familiar with and understands the proper cylinder storage, transport and testing procedures. Specimens will be delivered to the Testing Agency by the Contractor. The concrete compressive strength tests will be performed by the Testing Agency. Concrete Mixes (Specification Sections 014000, 033000) Concrete mixes will be provided for cursory review and comments concerning workability, pumpability, and general strength and durability considerations. Reinforcing Steel (Specification Sections 014000, 032000) Size, quantity, clearance to the edge of form, location, length, hook orientation and lap splice length of reinforcing steel will be verified. Reinforcing steel will be inspected for proper support to prevent displacement during concrete placement.
