Fabrication Inspection7.1 Reinforcing Steel:7.1.1 The inspector shall check all reinforcin

16、g steel todetermine that it has been covered by mill reports, with data inreports conforming to designated standard, and has not beendamaged. Material with kinks or bends not indicated onfabrication drawings shall not be used. Heating to bendmaterial is not permitted, as specified in Specification C

17、 858.7.1.2 All reinforcing steel shall be free of loose rust and asspecified in Specification C 858. A light film of red rust is notobjectionable, as specified in Specification C 858.7.1.3 Reinforcing steel shall be checked for size, spacing,proper bends, and lengths in accordance with the drawings.

18、7.2 Assembled Reinforcing Inspection:7.2.1 All material shall be properly spliced and locatedaccording to the drawings.7.2.2 Reinforcing steel shall be secured in such a mannerthat shifting will not occur during handling of the cage orplacing of concrete. All chairs, bolsters, braces, and spacers in

19、contact with form and reinforcing rod shall be of material thatwill not deteriorate. The cage shall be properly positioned inthe form to provide the specified concrete cover over the steel.7.2.3 The inspector shall check electrical ground connec-tions or any other special items as specified.7.3 Hard

20、ware Inspection:7.3.1 Hardware shall be inspected to ensure compliancewith purchasers specifications.7.3.2 Hardware shall be placed and securely fastened atdesignated locations to prevent shifting or movement duringconcrete placing.7.3.3 Threaded inserts and duct terminators shall be free ofconcrete

21、 and other foreign matter.7.4 Concrete Inspection:7.4.1 Concrete shall be placed to prevent segregation, voidsor honeycombed areas. Placing of concrete shall be observed toensure that it is being placed properly in accordance withapplicable standards.7.4.2 The inspector shall observe condition of co

22、ncrete afterthe forms are removed. Surfaces shall be sound. Patching andfinishing shall be permitted to remove minor honeycomb.Chips, voids, and through cracks shall be repaired by anacceptable method in accordance with Specification C 858.Extensive voids, chips, through cracks, or deep honeycombsha

23、ll be referred to the design engineer or purchasers engineerfor method of repair or acceptability.7.4.3 The inspector shall observe that specified curing isprovided.7.5 Dimensions InspectionThe inspector shall measurefor overall dimensions (that is, length, width, height, wallthickness, and squarene

24、ss, etc.) the first concrete section ofeach type produced from each form. The tolerances shallcomply to the finished product in accordance to SpecificationC 858.8. Tests8.1 The inspector shall check results of slump tests, ifspecified, for compliance to specifications.8.2 The inspector shall review

25、compressive strength data onproduct covered. If not to specified strength, the inspector shallhave concrete tested by method and manner agreed uponbetween the manufacturer and purchaser.9. Nonconforming Material9.1 Material found not to be in conformance with Specifi-cation C 858 shall be rejected u
