CDM will prepare for review by the County, Draft Design Documents which will constitute a 50% design review submittal. The Draft Design Documents will include a preliminary grading plan, design details, other appropriate drawings, and an outline of specifications necessary to define the kinds of materials, type of systems and such other work as may be required. During the draft design process CDM will consider alternate design methods and materials suitable for closure to determine the most cost effective and efficient application. In addition, a construction cost estimate for the project will be prepared and provided by CDM. CDM will utilize construction cost estimators from our construction company subsidiary, CCI, during the project in order to give the County the best information regarding the estimated cost of the project. Cabarrus County will be able to utilize this information in the budgeting process to ensure sufficient funds are available to complete the project. Two weeks after submitting the Draft Design Documents, CDM will meet with Cabarrus County to review and discuss the details of the closure drawings and specifications, along with the overall requirements of the project. At the conclusion of the meeting, it is anticipated that the County will provide written comments to CDM regarding additions, deletions, clarifications and changes that should be incorporated into the Final Design Documents. TASK 4 -GAS COLLECTION/VENTING SYSTEM DESIGN In addition to final closure design, CDM will include in the design a permanent gas collection/ venting system to be incorporated into the closure cap design and construction. Design will include gas collection trenches with passive gas vent risers up through the closure cap. As discussed with the NCDENR Solid Waste Section, this will replace the need for vertical gas wells in waste and will address the need for gas collection and venting following closure of the existing C&D Landfill. This represents additional design services in lieu of the installation of vertical gas wells and costs associated with drilling, gas well installation and CDM field time, as well as reporting, survey, future monitoring, etc. Although originally identified as a separate task in the FY 2007 budget, the proposed gas collection and venting system will now be incorporated into the C&D Landfill closure as a separate design task. This represents an increase over the estimated FY 2007 budget for closure design for the reasons stated above. TASK 5 -DESIGN REVIEW MEETINGS During the design process, CDM will conduct two design review meetings, one at 50% design and one at 95 % design to review the design documents with Cabarrus County and incorporate recommended design comments into the Final Design Documents. TASK 6 -FINAL DESIGN DOCUMENTS Following approval of the Draft Design Documents, CDM will prepare working drawings and specifications setting forth the work in detail and prescribing work to be done, including materials; performance requirements; site work; testing requirements; landscaping; bidding information; proposal, contract and bond forms; general and supplementary general conditions for the contract; and any other information required to receive formal bids. Copies of the completed construction documents will be furnished to the County for review and shall Page 3 of 7 F -'l
