Procedure Review The following procedures were reviewed in regard to concreting activ-ities:
WP-IV-101, " Reinforcing Steel Placement," Rev. 1, 2/23/77 WP-IV-102, " Mechanical Splicing of Reinforcing Steel," Rev. 3, 11/21/78 2g7 205-3-
.
WP-IV-106, " Concrete Pre-Placement, Placement, and Post Placement," Rev. 4, 2/1/79 WP-IV-107, " Concrete Cold Joints" WP-IV-ll6, " Post Tensioning Tendon Installation and Protection" WP-IV-ll7, " Post Tensioning Embedded Items" Bechtel Specification flo.10466-C103, " Contract for Forming, Placing, Finishing and Curing of Concrete," Rev. 6, 2/16/79 Bechtel Specification tio.10466-Cll2, " Contract for Placing Reinforcing Steel" 4.
Observation of Concrete Work Activities Three concrete placements were made during the inspection.
The following activities associated with placements flo. OC 134-WO4, OC 131-WO8 and OC 121-W10 were inspected:
a.
Placement OC 134-WO4 Placement OC 134-WO4 involved an interior wall in the Auxiliary Building in Area 4 from elevation 2012'
-0" to the underside of slab elevation above (2023' -4").
C-0C 1921 R/9, C-0C 1922 R/6, C-0C 1923 R/6 and C-0C 1341 R/7 were designated as applicable drawings.
This placement was designated as a " difficult placement" and required a special instruction sheet.
The placement was comprised of 104 cubic yards of Design Mix flo. 47-C-1A-ti and was completed on April 2,1979.
(1)
Delivery and Placement delivery and placement was made by pumping the concrete through a si. eel pipeline.
An adequate number of concrete vibrators was being used for consolidation.
An adequate number of drop chutes (less than 5' from previous concrete surfaces) was being used.
-4-
.
(2)
Process Samoling Samples were taken during the placement.
The determination of slump was observed to have been made correctly and to meet the criteria specified (.1 inch to 5 inches).
(3)
Curing The curing compound (liquid membrane) specified was applied at the completion of the placement.
During the curing phase, it was observed that wet burlap was applied to the horizontal surfacas of the placement and that liquid membrane was being applied to vertical surfaces as the forms were removed. The curing met the specification requirements.
(4) Certification of Placement Personnel Training records were reviewed for one individual operating a vibrator. The records indicated that he had been provided several hours of training in the correct use of vibrators.
No items of noncompliance or deviations were identified.
b.
Placement No. OC 131-WO8 The placement is identi~ied as being an interior wall of the Auxiliary Building, elevation 2000' -0" to 2008', Areas 1 and 2.
Applicable drawing include C-0C 1314 R/5, C-0C 1311 R/7, C-0C 1913 R/6, C-0C 1920 R/8 and C-0C 1919 R/7.
Placement Preparation The forms were observed to be clean, tight and had been dampened in preparation for concrete placement.
The reinforcement was spaced correctly and had the correct distance to the forms. The preparation was inspected by quality control inspectors prior to placement.
Placement volume was estimated to be 172 cubic yards of Design Mix 47-C-1A-N.
In process sampling was in accordance with specifications.
No items of noncompliance or deviations were identified.
