16、t and the inspector shall check that fit-up require-ments are as specified.6.4 The inspector shall check that all materials conform torequirements of Specification C858.7. Fabrication Inspection7.1 Reinforcing Steel:7.1.1 The inspector shall check all reinforcing steel todetermine that it has been c

17、overed 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.7.1.2 All reinforcing steel shall be free of form releasecoatings and

18、loose rust as specified in Specification C858,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

19、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 incontact with form and reinforcing rod shall be of material thatwill not deteriorat

20、e.
