Inspection Procedure6.1 The inspector shall inspect forms, materials, and fabri-cated parts used in t

15、he product.6.2 During each inspection, the inspector shall examinecomplete units for all specified features that can be determinedby visual observation.6.3 The first section of each type of precast structure fromany set of forms shall be assembled by the manufacturerwithout grout and the inspector s

16、hall check that fit-up require-ments are as specified.6.4 The inspector shall check that all materials conform torequirements of Specification C 858.7. Fabrication Inspection7.1 Reinforcing Steel:7.1.1 The inspector shall check all reinforcing steel todetermine that it has been covered by mill repor

17、ts, 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.7.1.2 All reinforcing steel shall be free of form releasecoatings and loose rust as specif

18、ied in Specification C 858,although a light film of red rust is not objectionable.7.1.3 Reinforcing steel shall be checked for size, spacing,proper bends, and lengths in accordance with the drawings.7.2 Assembled Reinforcing Inspection:7.2.1 All material shall be properly spliced and locatedaccordin

19、g 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 incontact with form and reinforcing rod shall be of material thatwill not deteriorate. The cage shall b

20、e 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 Hardware Inspection:7.3.1 Hardware shall be inspected to ensure compliancewith purchasers specifications.

21、7.3.2 Hardware shall be placed and securely fastened atdesignated locations to prevent shifting or movement duringconcrete placing.7.3.3 Hardware and other embedded items shall be free ofform release coatings.7.3.4 Threaded inserts and duct terminators shall be free ofconcrete and other foreign matt

22、er.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 concrete afterthe forms a

23、re 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 honeycombshall be referred to the d

24、esign 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 squareness, etc.) the first con

25、crete 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 compressive strength da

26、ta 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 unless acceptance is aut
