6.3.5 When a third party laboratory does the testing, the CQC Engineer shall obtain advance copy of test results.

6.3.6 All testing shall be witnessed by a CQC Engineer.

6.3.7 All inspection, measuring and test equipment shall be checked or tested at prescribed intervals as indicated in the Calibration Report.

(1) All surveying equipment and other inspection, measuring or testing equipment shall be calibrated and maintained.

(2) The Calibration Certificates or reports must be issued and filed. The calibration certificates or reports must be available on site.

(3) Proprietary equipment such as 3.5m retractable pocket measuring tapes and spirit levels will not be calibrated.

(4) When testing is done by Third Party laboratory, calibration certificate shall be obtained for reference.

(5) All subcontractors must be required to demonstrate that they are implementing effective control on their own inspection, measuring and testing equipment. The CQC engineer shall check and monitor such control through formal quality inspection to ensure that the control is being effectively implemented.

(6) Calibrated machine shall be properly labeled, indicating date of calibration, the schedule of next calibration, and agency conducting the calibration.

(7) When labeling is not applicable, data must be available anytime for reference.

6.3.8 Calibration can either be done onsite or offsite. Qualified personnel or accredited agencies shall perform it.

6.3.9 All calibrated and checked equipment must be identified with suitable indicator to show calibration status. Label to include equipment number, next calibration date and deviated error. If labeling is not practical, identification record of the equipment must be available.

6.3.10Equipment found to be outside the acceptable tolerance must be rechecked. If it is still found to be non-conforming, it shall not be used or be removed from the site.

6.3.11Calibration Certificate of all testing equipment by third party laboratories shall be obtained for record purposes.

6.3.12Document Controller shall do material delivery, sampling and testing monitoring and tracking of document.

6.3.13Monitoring of results shall include the following but not limited to;

(1)

Submittal Status Log

(2)

Equipment Commissioning

6.4.1 Testing is an extremely important part of CQC. If tests are not performed properly, many construction procedures cannot be confirmed as adequate. Visual observation alone is insufficient. Refer to Testing Submission for testing requirements. Procedures (a) The Contractor is required to provide a list of required tests and specify whether the test are to be performed by an independent, approved testing laboratory or through the use of his approved personnel and facilities. (b) Regardless of which method of testing the Contractor uses, he is required to assure specified laboratory procedures are used in accordance with the Contract Specifications. (c) All test equipment and measuring devices shall be of the proper type, range and accuracy, and must be calibrated and meet the tolerances required in compliance with the test criteria. All equipment and devices shall be properly calibrated adjusted and maintained in accordance with acceptable standards. (d) Certificates of Calibration must be kept on file as required. Certificates shall show the date of last calibration, and the due date of the next calibration. All such certificates shall be available to the Engineer for review at his request.

(e) In case of testing by Third party Laboratory, Calibration certificate shall be obtained for the record. 6.4.2 Unless otherwise specified, the CQC group shall arrange for factory / field test when they are required under the contract. 6.4.3 CQC inspectors shall direct, witness and document the conduct and result of this test. Field test shall be re-done after required replacement for re-work is accomplished. Successful test shall be documented as such, and the tested item of work certified by the inspector, and in turn by the CQC Head. The Owner shall be notified at least 24 hours in advance on any test in order that he may witness the conduct of the test. 7.0

Excavation

1. Verify with the owner if the elevation reference on site conforms to the elevation reference on plan. 2. Survey existing surrounding structures elevation and current structure defects and have it noted by the owner of the structure or administration officer for future reference. This is important to negate future adverse claim due to the construction works. 3. Study the type of soil in the vicinity. Verify if the soil can hold steep slope excavation. If not provide adequate slope protection measures. 4.

Check if the foundation requires gravel bedding or lean concrete.

5. Excavate to the required depth considering the thickness of the gravel bedding or lean concrete.
