Materials Testing and Special Inspection Services <br />Our scope of services for the proposed projects will consist of materials testing and special inspection during <br />construction. Our understanding of the proposed projects will be based on the project plan sets and <br />specifications provided by the City. The anticipated tasks for our scope of services will consist of the following <br />field, laboratory and office work, generally presented in chronological order. <br />• Reinforcing Steel Source Sampling: We will pick up reinforcing steel samples and "tag" source materials <br />for site delivery identification. Sampled reinforcing steel will be tested in accordance with ASTM A370, and <br />A615 or A706. <br />Fresh Concrete Sampling, Batch Plant, and Testing: We will provide a technician certified by ACI for <br />reinforced concrete sampling and testing. The work will consist of sampling reinforcing steel and concrete <br />during construction. Our field technicians will sample fresh concrete, perform slump tests (ASTM C 143) <br />and (if requested) air content tests (ASTM C 173 or C 231) when requested by your designated field <br />representative. Air content tests will only be performed if specifically requested (not expected to be <br />required where there is no frost). We will mold at least four concrete compression test cylinders for each <br />50 cubic -yards of concrete, or at least one set of four each day concrete is placed. We will also provide an <br />ACI technician during concrete batch plant operations. Our batch plant visits will consist of checking batch <br />weights, aggregate stockpiles and cement bins. <br />Post -Installed Anchors/Epoxy Dowels Special Inspection: We will provide a special inspector that has <br />been certified by the International Code Council (ICC) to observe installation of powder driven anchors, <br />expansion anchors, adhesive anchors and dowels. Our special inspector will view installation of these <br />anchors in accordance with ICC/ESR requirements, specific to anchors used. Our special inspector will <br />also evaluate drill bit compliance, hole depth and cleanliness, rod diameter, length of embedment, ambient <br />temperature, material condition, product description and name, and adhesive shelf life and condition of <br />packaging. If required, we will also provide pull/torque and/or proof testing of post -installed anchors. <br />Structural Steel (Field Welding): We will provide an American Welding Society (AWS) Certified Welding <br />Inspector (CWI) to inspect structural steel welding and high -strength bolting on site. Their work will consist <br />of periodic inspection of all single -pass fillet welds less -than (<) 5/16-inch-thick; and continuous inspection <br />for all multi -pass fillet -welds greater -than (>) 5/16-inch-thick plus all complete penetration welds made <br />during structural steel erection on site. Our CWI will also tabulate/record all inspected welds, including <br />listing defective welds and documenting correction of defects. Our CWI will also check material, <br />equipment, details of construction and procedures. They will also check ability of the welder. Upon <br />completion of all welding for this project, a verified report will be provided to document that inspected <br />welding was proper and completed in accordance with approved structural plans and specifications. <br />Nondestructive Testing (NDT): We will provide an NDT Technician to perform ultrasonic testing and <br />magnetic particle testing as required by the approved plans. <br />• High -Strength Bolting and Testing: We will provide a special inspector to inspect tightening or torqueing <br />of high -strength bolts during construction. Samples of the bolt assembly (bolt, washer and nut) will be <br />tested in the laboratory, as applicable, for hardness, proof load and wedge tensile. <br />• Structural Steel Shop Welding: We will provide an American Welding Society (AWS) Certified Welding <br />Inspector (CWI) with ICC structural steel and bolting to verify and inspect steel during shop fabrication and <br />construction in the field. Their work will consist of periodic and/or continuous inspection of: <br />Material identification <br />Steel frame joint details for conformance with approved structural plans <br />Welded connection of structural steel and cold -formed steel deck, and reinforcing steel, if required. <br />Our CWI will also tabulate/record inspected welds, including listing defective welds and documenting <br />correction of defects. Our CWI will also check weld filler materials, equipment, welding procedure <br />specifications, and ability of the welder, as necessary. Our inspector may use non-destructive testing such <br />
