As previously discussed, the major elements of the project were designed to address these objectives. Project requirements for construction quality control and construction quality assurance are defined in the Golden Gilpin Mill Site Mine Reclamation Construction Documents (WRC 2005). Each section of the project specifications contained information or requirements as appropriate for standard references, submittals, quality assurance, installation and testing. The construction contract outlined a number of quality assurance requirements to be met by the contractor during project construction. The primary document governing construction Quality Assurance/Quality Control (QA/QC) was a QA/QC Plan submitted by the contractor and approved by the engineer. The QA/QC plan outlined organizational and schedule control,record keeping and reporting requirements, and submittals and testing requirements. In addition to approving the QA/QC Plan, the engineer was also responsible for reviewing and approving all material submittals and test results to ensure compliance with project specifications. CDPHE staff performed periodic construction oversight of the project,with support from the project engineer. Additional quality assurance was provided through geotechnical and materials testing performed as specified in the construction documents. Geocal Inc., a local consultant, was retained by CDPHE to perform all geotechnical and materials testing required by the project. The project engineer reviewed and approved all test results. The engineer was also on- site as needed for progress meetings and during select times during construction to ensure that all work was performed in compliance with the construction drawings and specifications. VI. FINAL INSPECTION AND CERTIFICATION CDPHE developed an initial punch list for project completion on July 29, 2008. On that date, a pre-final inspection of the clean up was conducted by Doug Jamison of CDPHE with Nathan Torrey of WRC and Josh Romans of LHE in attendance. The final inspection was conducted on September 19, 2008. Attendance at the final inspection consisted of the Doug Jamison of CDPHE and Scott Aschenbrenner of LHE. On September 23, 2008, a final site walkthrough was conducted by CDPHE and WRC Engineering Inc. The pre-final and final inspections consisted of reviewing each specific construction activity outlined in the contract documents. Deficiencies were noted on the inspection checklist and the contractor was notified verbally at the time of inspection and in writing. All of the deficiencies noted during the pre-final inspection had been corrected at the time of the final inspection. At the time of the final inspection, all punch list items identified during the pre-final inspection, except for final demobilization, had been completed at the time of the final inspection. Final demobilization had been completed when CDPHE and WRC conducted a final site walkthrough on September 23, 2008. At the date of this report, the only work remaining under the construction contract between CDPHE and LHE is completion and submittal of as-built construction drawings and any warranty work that might be necessary. A warranty inspection will be conducted in August of 2009.
