SUBJ: Approve Change Order No. 1 to Market Square Storm Sewer,
' Bus Shelter Relocation Project No. 90-13
The Market Square Shopping Center development is expected to open for business in
' October of this year. One of the development commitments made by the City was to
provide a right turn lane access to the site at mid -block between Kerber Boulevard and
Market Boulevard. This work was previously proposed to be included as a part of the
' overall West 78th Street Detachment Project; however, due to circumstances involving the
potential Target site to the west, the detachment project has been delayed and is not
expected to be constructed until 1993.
The City currently has an open contract with Ryan Construction Company for the Market
Square Storm Sewer Improvement Project and Bus Shelter Relocation. This project is
nearly complete. We have contacted the contractor about the possibility of adding a change
order to the original contract which would specify the specific work items for construction
of the right turn lane off of West 78th Street into the Market Square development. The
1 change order amounts to a total of $19,188.00.
Given the timing of the Market Square development project and previous commitments
1 made by the City, staff believes it is appropriate to remove this right turn lane improvement
work from the West 78th Street Detachment project and add it to the active Market Square
Storm Sewer improvement contract. This improvement could be completed yet this fall.
It is therefore recommended that Contract Amendment No. 1 for the Market Square Storm
Sewer Extension Project No. 90-13 be approved.
