Construction Quality Assurance(CQA) Plan Extension of Closure Cap <br /> Corral Hollow Sanitary Landfill August 21, 2008 <br /> determined by additional sampling, testing, observations, review of records, or any <br /> other means deemed appropriate. <br /> 2.4.3 Documenting Non-Conformance <br /> All non-conformance must be documented in writing on the daily records, logs, and <br /> elsewhere, as appropriate. The documentation must occur immediately upon <br /> determining the extent of the non-conformance. For a non-conformance which is <br /> considered serious or complex in nature, or which requires an engineering evaluation, a <br /> Non-Conformance Report will be prepared and issued to the construction manager and <br /> Contractor. <br /> 2.4.4 Corrective Measures <br /> For a simple or routine non-conformance, corrective measures will be determined by <br /> specification direction, or if none exists, the construction manager, CQA Manager and <br /> Contractor will discuss standard construction methods to correct the deficiency. For <br /> Non-Conformance Reports, which require engineering evaluation, the design engineer <br /> must determine corrective measures. A copy of the Non-Conformance Report, with the <br /> design engineer's corrective measure determination, will be forwarded to the <br /> construction manager, CQA Manager, and Contractor for implementation of the <br /> corrective action. <br /> 2.4.5 Verification of Corrective Measures <br /> Upon notification by the Contractor that a corrective measure is complete, the CQA <br /> manager will verify its completion. The verification must be accomplished by <br /> observations or retesting and documented photographically. Written documentation of <br /> the corrective measures must be made by the CQA Manager on daily reports, logs, and <br /> forms, and, if applicable, the Non-Conformance Report. Verification of corrective <br /> measures will be reviewed by the CQA Officer. Corrective action measures that <br /> require an engineering evaluation will be reviewed and verified by the design engineer. <br /> Vector Engineering, Inc. •143E Spring Hill Drive -Grass Valley, CA• (530) 272-2448 <br /> -12- <br />
