2023 C&D Landfill Annual Survey and Airspace Analysis
Proposal for Survey & Engineering Services
Draper Aden Proposal No. TBD Lump Sum Fee = $7,000
(2021 PN: 2100778)
At your request, Draper Aden Associates (DAA) is pleased to offer this proposal for Aerial Services for
the Construction and Demolition (C&D) landfill located at the Orange County Regional Landfill Facility
on Eubanks Road in Chapel Hill, NC. This proposal outlines our understanding of the project scope,
tasks to be completed, assumptions underlying our fee proposal, and fees for the project.
PROJECT DESCRIPTION: The project consists of aerial survey services using a drone and conventional
survey to produce a topographic survey of the C&D landfill. Data gathered will be used to conduct an
analysis of the airspace used within Phase 1 and 2 of the C&D landfill.
SCOPE OF SERVICES
Surveying: DAA will conduct an aerial topographic survey with an sUAS /drone aircraft of the area
associated with Phase 1 and 2 of the C&D landfill unit, approximately 15 acres. An FAA licensed
Remote Pilot will conduct flight operations in accordance with FAA rules and regulations. Aerial flights
are dependent on safe weather conditions. The topographic survey will include setting and locating
Ground Control Points and performing check point measurements. The images collected using the
sUAS will be photogrammetrically processed to make a 3D Point Cloud and orthomosaic image of
the entire project area. A draftsman will use the photogrammetric output to generate the earth
surface and contours at one-foot intervals.
Analysis: DAA will provide an estimate of the total volume of air space used at the C&D Landfill on
Eubanks Road. In order to complete this task, DAA will use the survey produced in the task above, to
compare to the design base grades of the landfill to the permit air space limits to determine the
amount of fill that has been placed since the landfill’s inception and also since the 2021 annual

survey. In addition, DAA will obtain tonnage from the Client for the time period between the 2021
and 2022 annual survey to assess compaction rates for the C&D facility.
FEES: These lump sum fees will be invoiced monthly based on our estimation of the percentage
complete on each task.

DELIVERABLES: The project deliverables will consist of a high resolution orthomosaic photo base
image and topographic plat without base image. Drawings are to be in AutoCAD format and presented
to the client in PDF form. Two (2) hard copy mounted prints of the aerial photograph, approximately
24” x 36” in size will be provided. In addition, DAA will generate a memorandum for file detailing the
results of the airspace and compaction analysis.
