1910.1.1 Construction documents. Openings larger than 12 inches (305 mm) in any dimension shall be detailed on the structural drawings.

1910.2 Tests and materials.

Where required, special inspec- tions and tests shall be in accordance with Chapter 17 and this section.

1910.2.1 Cementitious material. The concrete supplier shall furnish to the enforcement agency certification that the cement proposed for use on the project has been man- ufactured and tested in compliance with the requirements of ASTM C150 for Portland cement and ASTM C595 or ASTM C1157 for blended hydraulic cement, whichever is applicable. When a mineral admixture or ground granu- lated blast-furnace slag is proposed for use, the concrete supplier shall furnish to the enforcement agency certifica- tion that they have been manufactured and tested in com- pliance with ASTM C618 or ASTM C989, whichever is applicable. The concrete producer shall provide copies of the cementitious material supplier’s certificate of compli- ance that represents the materials used by date of ship- ment for concrete. Cementitious materials without certification of compliance shall not be used. 1910.2.2 Tests of reinforcing bars. Samples shall be taken from bundles as delivered from the mill, with the bundles identified as to heat number and the accompanying mill certificate. One tensile test and one bend test shall be made from a sample from each 10 tons (9080 kg) or frac- tion thereof of each size of reinforcing steel.

Where positive identification of the heat number cannot be made or where random samples are to be taken, one series of tests shall be made from each 2 1 /2 tons (2270 kg) or fraction thereof of each size of reinforcing steel.

Tests of reinforcing bars may be waived by the struc- tural engineer with the approval of the building official for one-story buildings or nonbuilding structures, provided that they are identified in the construction documents and certified mill test reports are provided to the inspector of record for each shipment of such reinforcement. 1910.2.3 Tests for prestressing steel and anchorage . All wires or bars of each size from each mill heat and all strands from each manufactured reel to be shipped to the site shall be assigned an individual lot number and shall be tagged in such a manner that each lot can be accu- rately identified at the job site. Each lot of tendon and anchorage assemblies and bar couplers to be installed shall be likewise identified.

The following samples of materials and tendons selected by the engineer or the designated testing labora- tory from the prestressing steel at the plant or job site

debris, dirt and dust. Concrete and masonry shall be brought to a saturated surface-dry (SSD) before shot- crete is deposited.

1909.3.9 ACI 318, Section 26.12.2.1(a). Replace ACI 318 Section 26.12.2.1(a) by the following:

26.12.2.1(a) - Samples for strength tests of each class of concrete placed each day shall be taken not less than once a day, or not less than once for each 50 cubic yards (38.2 m 3 ) of concrete, or not less than once for each 2,000 square feet (186 m 2 ) of surface area for slabs or walls. Additional samples for seven-day com- pressive strength tests shall be taken for each class of concrete at the beginning of the concrete work or whenever the mix or aggregate is changed.
