(a) General. Tests of materials are required as set forth in these rules and regulations. Other materials or combinations of materials may require additional tests. Where job conditions warrant the architect or registered engineer may waive certain tests with the approval of the office.(b) Performance of Tests. The school board with the approval of the architect or registered engineer shall select a qualified person or testing laboratory as the testing agency to conduct the tests. Test samples or specimens of material for testing shall be taken by the architect or registered engineer, his representative, the inspector, or a representative of the testing agency. In no case shall the contractor or vendor select the sample.
Sampling, preparation of samples and tests shall be in accordance with the standards as provided for in the approved specifications or in the applicable building regulations.
Where a sample has failed to pass the required tests the architect or engineer, subject to the approval of the office, may permit retest of the sampled material. In such cases two new samples shall be tested and the material shall be rejected if either sample fails.
(c) Payments. The school board shall pay for all tests but if so specified the amount or a portion thereof may be collected from the contractor. When in the opinion of the architect or registered engineer, additional tests are required because of the manner in which the contractor executes his work, such tests shall be paid for by the school board, but if so specified the amount paid may be collected from the contractor. Examples of such tests are: tests of material substituted for previously accepted materials, retests made necessary by the failure of material to comply with the requirements of the specifications, and load tests necessary because certain portions of the structure have not fully met specification or plan requirements.(d) Test Reports. One copy of all test reports shall be forwarded to the office, the architect, the structural engineer and the inspector by the testing agency. Such reports shall include all tests made, regardless of whether such tests indicate that the material is satisfactory or unsatisfactory. Records of special sampling operations as required shall also be reported. The reports shall show that the material or materials were sampled and tested in accordance with the requirements of these rules and regulations and with the approved specifications. In the case of masonry or concrete, test reports shall show the specified design strength. They shall also state definitely whether or not the material or materials tested comply with requirements.(e) Verification of Test Reports. Each testing agency shall submit to the office a verified report in duplicate covering all of the tests which were required to be made by that agency during the progress of the project. Such report shall be furnished each time that work on the project is suspended, covering the tests up to that time, and at the completion of the project, covering all tests. The verified report shall contain all the information included in the Sample of Laboratory Verified Report (see Appendix).
