I SUBJ: Approve Contract Amendment No. 1 for
Phase II , Downtown Redevelopment
Project No. 86-11B
IIPhase II of the downtown redevelopment is also coming to a rapid
conclusion. As the project progressed, certain elements of the
I project scope were modified by necessity. The widening of Market
Boulevard, for example, was to accommodate turn lanes for the
Crossroads National Bank site as well as the decision to
construct a full-movement intersection at Market Boulevard with
I Trunk Highway 5 to accommodate the Rosemount Engineering traffic
demands. This element comprises $47,089 . 92 of the $58,752 .17
contract amendment.
IThe modifications to the electrification of fountains A and B in
the storm water detention pond resulted from the decision to add
I the second fountain to the project scope. This had been antici-
pated in the Phase I construction element and has been necessi-
tated from and aesthetic and water quality standpoint. Elements
C and D of the change order are relatively straightforward
Iresulting from the change in scope and field conditions.
I have found the attached contract amendment to be in order and
11 the recommended addition is within the construction budget allo-
cated for this project. It is therefore recommended that
Contract Amendment No. 1 for Phase II of the downtown redevelop-
!' project be approved in the amount of $58, 752.17 and that the
contract ceiling amount be increased to $702,180. 50.
