Manufacturers Responsibility4.1 The manufacturer shall develop and use an effectivequality control program that shall include material controls,tests, and inspections as agreed upon between manufacturerand purchaser throughout

7、 the fabrication process.4.2 The manufacturers inspection records and associatedtest data shall be made available to the inspector.4.3 The manufacturer shall notify the inspector of anychanges in material, method of fabrication, or quality controlprocedure.4.4 The manufacturer shall designate an ind

8、ividual as liai-son to the inspector. He will sign the inspection activity reports,and when necessary, will be available to the inspector todiscuss matters pertaining to inspection, fabrication, and qual-ity control.4.5 The manufacturer shall prepare sufficient concrete testcylinders to meet the pur

9、chasers requirements for compressivestrength. Test cylinders shall be prepared in accordance withPractice C31/C31M or C1758/C1758M and tested in accor-dance with Test Method C39/C39M. Results shall be entered inan inspection activity report.4.6 The manufacturer, upon request, shall assemble (without

10、grout) selected concrete component sections to form a com-plete structure assembly to determine that fit-up requirementsare as specified.4.7 The manufacturer shall provide marking according topurchaser requirements or according to Specification C858.5. Inspectors Responsibility5.1 The inspector shal

11、l familiarize himself with the manu-facturers quality control program.5.2 The inspector shall determine that the fabrication of theprecast units complies with drawings approved by thepurchaser, including hardware and general requirements.5.3 The inspector shall immediately report to the purchaserand

12、 manufacturer any component parts, complete structures,etc., not in compliance.5.4 The inspector shall clearly indicate on the inspectionactivity report any fabrication problems encountered andsolutions utilized.6. Inspection Procedure6.1 The inspector shall inspect forms, materials, and fabri-cated

United States16.2 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

16、precast structure fromany set of forms shall be assembled by the manufacturerwithout grout 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 S

17、teel:7.1.1 The inspector shall check all reinforcing 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 bendmateria

18、l is not permitted.7.1.2 All reinforcing steel shall be free of form releasecoatings and 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 dr

19、awings.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 spa

20、cers incontact 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

21、.3 Hardware 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 Hardware and other embedded items shall be free ofform

22、release coatings.7.3.4 Threaded inserts and duct terminators shall be free ofconcrete 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

23、accordance withapplicable standards.7.4.2 The inspector shall observe condition of concrete 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

24、with Specification C858.Extensive voids, chips, through cracks, or deep honeycombshall 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 measur

25、e foroverall dimensions (that is, length, width, height, wallthickness, and squareness, etc.) the first concrete section ofeach type produced from each form. The tolerances shallcomply to the finished product in accordance to SpecificationC858.8. Tests8.1 The inspector shall check results of slump t

26、ests, ifspecified, for compliance to specifications.8.2 The inspector shall review 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 Ma

27、terial found not to be in conformance with Specifi-cation C858 shall be rejected unless acceptance is authorized.10. Evidence of Inspection and Reporting10.1 Inspection documents, etc., shall be in accordance withthe specifications.10.2 Inspection records on products completed and shippedbetween ins
