The budget for this task is included in Amendment No . 2 to Work Order No . 9 . No additional budget <br /> is necessary. <br /> Subtask 1 . 3 - Preliminary Site Plan <br /> The Oslo CCC is located at a closed landfill . Existing information obtained in Task 1 . 2 will be used to <br /> estimate the limits of waste areas , existing asphalt pavement, stabilized limerock, and compacted <br /> natural soil . A preliminary site plan will be developed for use in preapplication meetings with <br /> Regulatory agencies . The site plan will include layout of the access road and the future facilities <br /> which will be needed, such as proposed buildings and a stormwater detention pond . The <br /> preliminary site plan will be based on information obtained during the IRC SWDD meeting (Task <br /> 1 . 1 ) . The budget for this task is included in Amendment No . 2 to Work Order No . 9 . No additional <br /> budget is necessary. <br /> Subtask 1 . 4 - Site Investigation <br /> Subtask 1 . 4. 1 Subsurface Investigation <br /> As part of the original design, CDM performed a subsurface investigation to explore the subsurface <br /> soil conditions and evaluated the limits of waste within the proposed facility location . Soil borings , <br /> test pits , and piezocones were performed to explore the limits of waste and for the foundation <br /> design and site preparation of the new convenience center. The geotechnical exploration did not <br /> include environment/ chemical sampling or testing of the materials or groundwater encountered <br /> within the site . <br /> CDM prepared a geotechnical report summarizing the results of the subsurface investigation <br /> program, including existing geotechnical investigations . The summary includes results of the <br /> boring and test logs and results of laboratory classification testing of the selected samples . <br /> Recommendations for foundation design and site preparation based on the " elevated " structure <br /> design with a driven pile system were included in the report. <br /> Under this task, CDM will update the geotechnical report to revise the recommendations for the <br /> foundation design and preparation based on the new " on - grade " layout utilizing compactors for <br /> residential solid waste and roll - off containers for recyclables . <br /> Subtask 1 . 5 - Preparation of Design Drawings <br /> CDM will prepare permitting/ construction drawings of the proposed improvements which shall <br /> show the location, size, and spatial relationships between existing and proposed structures , <br /> equipment, and other improvements . CDM will subcontract the architectural , structural, <br /> HVAC / Plumbing and landscape/ irrigation design services to John H . Dean Architect & Associates <br /> and the electrical design services to Smith Engineering Consultants , Inc . All civil and geotechnical <br /> engineering design will be performed by CDM . The level of detail and information to be shown on <br /> the drawings shall be in conformance with generally accepted standards of the engineering and <br /> construction industry. Drawings shall be prepared using AutoCAD 2005 . It is anticipated that the <br /> Drawing set will include the following engineering disciplines : <br /> ® General ( CDM ) <br /> ■ Civil (CDM ) <br /> ■ Structural (John H . Dean Architect & Associates) <br /> A - 3 j13215_Revised.doc <br />
