Use of Qie correct mix designs will be veriiled in the field, The tests will be performed by an ACI certified engineering technician and will be in accordance with applicable ASTM methods. • L.abaratorv Testing -Concrete: Concrete cylinders fabricated during placement wpl be tested for compressive sirengih in our Laboratory. One specimen from each set of concrete cylinders will be tested at 7 days following placement and two will be tested at 2t3 days. One speclman from each set will be held in reserve in fife event that the concrete strength is below the specified requirements. for the placement of time- critical concrete elements of the structure, an additional concrete specimen may be fabricated For a compressive strength test prier to the 7-day ~ast- Laboratorv Tasting -Grout: Grout specimens will be fabricated during structural CMU wall construction. The samples will be tested for compressive strength in our laboratory. One speclman from each set of specimens wilt be tested at 7 days following placement and flue will be tested at 28 days. One specimen fram each set will be held in reserve in the event that the grout strength is below the specified requirements. • Structural Concrete Reinforcement: The reinforcing steel in the foundations, elevated decks, and slabs-on-grade will he observed to confirm proper size, location, spacing, fastening, and cover. Anchor bolts and bearing plates will be observed to confirm proper installation. Field Observations of tructural Maso r : During structural masonry wall construction, we wi11 periodically observe the placement of the reinforcing steel within the iiollo~v CMU units and ensure that the space to be grouted is clean. We will continuously field test the grout fill to be placed. The samples will be tested for compressive strength in our laboratory. • Structural Steel Inspection: CESi protect engineers will perrorm periodic Inspections of shop and field welded connections as well as bearing artd slip•critical bolted connec#ions as specified in the protect documents. Bolted connections will be tested for proper torque if required. in addition, high strength bolts, nuts, and washers will be inspected For material verification. • Re ortin -Dally hand-written reports will be provided dally. Formal reporting of evaluations and test results will be provided in typed form. Any det(clencies in the observedllested quality of the materials or work that are not Corrected will be communicated to the appropriate protect personnel via telephone or facsimile. If there are any services that you wish to add to or delete front this list, please let us know. All field and laboratory tests will be completed in accordance with applicable ASTM, ACI, AWS, and RISC procedures. RESPONSIBILITIES Our presence at the job site and our performance of qualify assurance testing must not be construed as relieving the contractor fram Isis responsfbifity to comply tivith the plans and specifications, Quality assurance testing is conducted on a representative sample of the construction materials and work performed. Our services are not in any way related to job- site safety. Otrr representatives do not have the authority to supervise the work nor to direct contractor personnel. In performing our services, our engineering representatives will use a standard of care consistent with reasonable and prudent construction materials testing gild special inspection practices in the Cabarrus County area, and wilt make a conscientious effort to cheek that the contractor compiles with the contract documents. We request that scheduling of our services be provided at least 24 hours prior to our being on site.
