ST8801-CS 920629TO: Frank Trando, Finance Director
FROM: Kenneth M. Griffin, P.E., City EnGineer ~
SUBJECT: Request of Cost Estimates for Sandy Lake Intersections
and Coppell Road
DATE: June 29, 1992
Transmitted via this memo, you will find attached a copy of some
preliminary rough cost estimates for the followinG:
Sandy Lake/MacArthur Intersection
Sandy Lake/Moore Intersection
Coppell Road from Plantation to Sandy Lake
Coppell Road from Plantation to Bethel Road
These cost estimates represent my best estimate as to what the cost will
be for the permanent construction of each of these projects. Please bare
in mind that an exact cost estimate cannot be obtained until the projects
have been designed and exact quantities have been arrived at. However,
these costs are based on available bid tabulations from other sources.
None of these cost estimates include the associated cost for the purchase
of right of way. Also, various drainage improvements, as identified by
the Albert H. Halff DrainaGe Study, have been included in the cost of
these projects. In particular, I included the Moore Road drainage
improvements north of Sandy Lake and the Coppell Road BridGe improvements
immediately north of Bethel Road.
I will be available at or before the July 22, 1992 City Council meeting to
discuss any portion of these cost estimates as needed. AGain, they are
preliminary rough estimates based on the best available current
information.
If you have any additional questions, please feel free to contact me at
your convenience.
