Approve Engineering Services Contract Supplement for
TH 5/West 78th Street Improvement Project No. 97-6, S.P. 1002-61
The design services contract with Barton-Aschman Associates, Inc. to include
City utility infrastructure in the Trunk Highway 5/West 78th Street Improvement
Project was approved by the Chanhassen City Council on February 24, 1997.
Barton-Aschman Associates, Inc. is the design firm selected by MnDOT to
perform the design work for the improvement-project. As part of the overall
project, the City incorporated the utility infrastructure plan for the area to be
constructed concurrent with the Highway 5 project.
The approved design services contractis in a not-to-exceed amount of $30,724
based upon the estimated scope ofwork for the Utility infrastructure. Barton-
Aschman Associates, Inc. requested and City COuncil approved in May of 1999 a
supplement to the design services contract in the amount of $4,200 based upon the
actual length of watermain designed, number of hydrants and vanes required and
the additional work required above and beyond that known at the time of the
original contract for the utilities being designed between Century Boulevard and
TH 41. This resulted in a revised contract amount of $34,805.
The cun'ent request for a supplement to the engineering services contract is a -
result of the necessity to prepare a variance requeSt for a design exception to
federal bikeway design standards for bike paths located at the approaches to Riley
Creek and Bluff Creek underpasses along'TH 5 and West 78th Street. Design
variance requests are reviewed by a variance board whiCh meets twice a year. It is
necessary for the supporting documentation for the variance justification be
submitted to MnDOT prior to November 15, 1999. BartOn-Aschman Associates,
Inc. has estimated an amount of $2,700 will be necessary to complete the work in
conformance With State Aid requirements.
This additional work could not have been anticipated when the original scope of
services was defined for this project and the design exception to the federal
bikeway design standards is necessary to insure federal funding for the bike paths
at the Riley and Bluff Creek underpasses. I have evaluated this request and
recommend the City Council approve the supplement to the design services
contract in the amount of $2,700 for a total revised contract amount of $37,505..
