Source Quality Control. 1. Testing laboratory shall provide continuous inspection at concrete batch plant for all structural concrete, defined as follows:
a. Footings, foundation walls, floor slabs‐on‐grade, exterior reinforced slabs.
Source Quality Control. 5.2.1. Ensure that Work meets specified requirements
5.2.2. Schedule, supervise and administer inspection and testing as specified in Section 01 45 00.
Source Quality Control. Obtain approval from Contract Administrator of plant material at source.
Source Quality Control. 4.1 Obtain approval of selected limestone sedimentary planes as source. When proposed source has been approved, use no other source without written authorization.
Source Quality Control. E31.4.1 Prior to delivery to the site, inform the Contract Administrator in writing of gabion fill rock source, and obtain approval.
Source Quality Control. A. Inspection and Testing will be performed under provisions of Section 014000.
B. Testing Laboratory will:
1. Review mix designs and certificates of compliance for materials Contractor proposes to use.
2. Inspect batch plant as they deem appropriate to verify plant quality controls are adequate. Obtain sample of aggregates when it appears they may not conform to requirements specified.
3. Observe batching of mixes that contain high range water reducing admixture. Confirm type and quantity of admixture.
Source Quality Control. A. Inspection and testing will be performed under provisions of Section 014000.
B. Testing Laboratory will:
1. Review manufacturer's test reports for compliance with specified requirements.
2. Verify material identification.
3. Inspect high-strength bolted connections as required by CBC Section 1701A for conformance with RCSC Specification. Bolts in connections identified, as shear/bearing need not be inspected for bolt tension.
4. Inspect welding as required by CBC Section 1701A in accordance with AWS D1.1. The following should be performed for each weld:
a. Verify Welding Procedure Specification (WPS) sheet has been provided and has been reviewed with each welder performing the weld. Welds not executed in conformance with the WPS are rejectable.
b. Verify fit-up meets tolerances of WPS and mark joint prior to welding.
c. Verify welding consumables per Contract Documents and WPS.
d. Verify welder qualification and identification.
e. Verify amperage and voltage at the arc with hand-held meters.
f. Observe preheat and interpass temperatures, weld pass sequence and size of weld bead.
5. Nondestructive test all complete penetration groove welds larger than 5/16 inches by ultrasonic methods for conformance with the weld quality and standard of acceptance of AWS D1.1 for welds subject to tensile stress. Pass sound through the entire weld volume from two crossing directions to extent feasible.
6. Periodically, inspect and test stud welding as required by CBC Section 1701A in accordance with AWS D1.1; review preproduction testing and qualification, periodically inspect welding and perform verification inspection and testing.
Source Quality Control. 1 Upon request, provide Contract Administrator with certified copy of mill test report of reinforcing steel, showing physical and chemical analysis. .2 Upon request inform Contract Administrator of proposed source of material to be supplied.
Source Quality Control. (a) Arrange for a plant inspection by Contract Administrator where specified.
(b) Inform Contract Administrator of manufacturing progress and arrange inspections at appropriate times.
(c) Action required by factory inspection shall not be construed as final acceptance.
(d) Obtain a Certificate of Acceptance from the inspection authority on completion of the Work and provide it to the Contract Administrator.
(e) The Contract Administrator may carry out inspections and prepare deficiency lists for action by the Contractor, during and on completion of project.
Source Quality Control. A. Testing Agency: Engage a qualified testing agency to perform shop tests and inspections.
