Attention: Mr. Ralph Ridley, Engineering Supervisor
Dear Mr. Ridley,
Aero-Metric Engineering, Inc. is pleased to provide the cost for Aerial Photo-
graphy and Topographic Mapping. The project area is located in Sections 4, 5,
8, and 9, Township 41 North, Range 8 East, Kane County, Illinois. The area is
delineated on the enclosed map.
AERIAL PHOTOGRAPHY
Color aerial photography will be acquired as soon after notice to proceed as
weather and site conditions permit.
GROUND CONTROL
Guillou & Associates, Inc. will conduct the necessary horizontal and vertical
control field surveys required for our mapping operations. We will provide a
set of 9" x 9" color contact prints which will be annotated with the desired
control identities. Guillou & Associates, Inc. will post the adjusted
coordinates and elevations upon these prints within the spaces provided. These
prints will be returned to our office.
MAPPING
Upon completion of the aerial photography and ground control surveys, our tech-
nicians will prepare topographic mapping of the project area. The mapping will
be completed at two scales. First, the overall area will be completed at
1"=100' and have a 2' contour interval . Second, the two embankment areas will
be completed at 1"=50' with a 1' contour interval . All mapping will be com-
pleted in autopositive form or final drafted by the scribe (negative engraving)
method.
All mapping will be guaranteed to meet or exceed National Map Accuracy Stan-
dards for 1' and 2' contour interval mapping.
