Tyrus Clayton, Jr., PE <br /> Principal <br /> DATE: April 5, 2020 <br /> SUBJECT: Orange County Regional Landfills <br /> 2021 C&D Landfill Annual Survey and Airspace Analysis <br /> Proposal for Survey & Engineering Services <br /> Draper Aden Proposal No. 2100778 Lump Sum Fee = $5,700 <br /> At your request, Draper Aden Associates (DAA) is pleased to offer this proposal for Aerial Services for the <br /> Construction and Demolition (C&D) landfill located at the Orange County Regional Landfill Facility on <br /> Eubanks Road in Chapel Hill, NC. This proposal outlines our understanding of the project scope, tasks to <br /> be completed, assumptions underlying our fee proposal, and fees for the project. <br /> PROJECT DESCRIPTION: The project consists of aerial survey services using a drone and conventional <br /> survey to produce a topographic survey of the C&D landfill. Data gathered will be used to conduct an <br /> analysis of the airspace used within Phase 1 of the C&D landfill. <br /> SCOPE OF SERVICES <br /> Surveying: DAA will conduct an aerial topographic survey with an sUAS/drone aircraft of the area <br /> associated with Phase 1 of the C&D landfill unit, approximately 8 acres. An FAA licensed Remote Pilot <br /> will conduct flight operations in accordance with FAA rules and regulations. Aerial flights are dependent <br /> on safe weather conditions. The topographic survey will include setting and locating Ground Control <br /> Points and performing check point measurements. The images collected using the sUAS will be <br /> photogrammetrically processed to make a 3D Point Cloud and orthomosaic image of the entire project <br /> area. A draftsman will use the photogrammetric output to generate the earth surface and contours at <br /> one-foot intervals. <br /> An_ _ afgis: DAA will provide an estimate of the total volume of air space used at the C&D Landfill on <br /> Eubanks Road. In order to complete this task, DAA will use the survey produced in the task above, to <br /> compare to the design base grades of the landfill to the permit air space limits to determine the <br /> amount of fill that has been placed since the landfill's inception and also since the 2020 annual survey. <br /> In addition, DAA will obtain tonnage from the Client for the time period between the 2020 and 2021 <br /> annual survey to assess compaction rates for the C&D facility. <br /> Blacksburg, TA • Charlottesville, l',9 •11amplou Rowels, Y,4 •Northern Irrginia •Richniond, V4 <br /> Fa ,elleville, NC•Raleigh, NC <br />
