and make reco~endations for construction of the earthen dam as part of the basin. E~GINEERwill m~et with the geotechnical engineer and OWNER during initial investigation to review existing conditions at the proposed location of the basin. Up to three test borings will be performed along the proposed centerline of the earthen dam to develop a foundation analysis. Two test borings up to twenty feet in depth will be conducted in a potential barrow area and the soils analyzed in o~der to develop construction requirements and testing parameters for the earthen dam. In addition, two borings will be extended to auger refusal or twenty feet, whichever occurs first, in the proposed basin area to determine possible excavation depths. The results of the investigation, and recommendations for design and construction will be summarized in a report by the geotechnical engineer. Task 2.0 - Sedimentation Basin Design ENGINEER will prepare hydraulic calculations using Soil Conservation Service methods and the North Carolina ,'Erosion and Sediment Control Planning and Design Manual" to determine the required size of the sediment basin, the height of the earthen dam, pipe sizes, and final slope requirements. The calculations will be based on features shown on the existing topographic map, and the permitted final contours of the landfill. Task 3.0 - Preparation of Technical Specifications and Drawings ENGINEER will prepare technical specifications and drawings for construction of the sedimentation basin for incorporation into bid documents to be prepared by OWNER. The specifications will include recommended soil materials, test parameters, a bid form, method of payment, and construction techniques (developed from Task 1.0), as well as plan sheet(s), cross section(s) and details sufficient to construct 2of5
