Benson, City'Engineer ~/~ October 19, 1999 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..
