' SUBJ: Approve Contract Amendment No. 2 for North Side Parking Lot
Improvement Project No. 87-17
The North Side Parki ng project incorporates Lot 'ect which rates the area between the
�
Riviera Restaurant and Great Plains Boulevard was authorized under one
feasibility study. This project, like other projects in the downtown, has been
held hostage by the various development proposals such as the Medical Arts
building, Pauly property, Riviera improvements and the improvements to Colonial
' Center. As a result, the project was initially authorized to incorporate only
the east half improvements of the project site with the west half waiting for
construction of Phase II of the Medic al Arts building.
As is not uncommon in this development environment, it became prudent as the
project evolved to address the parking needs and concerns of the Phase I Medical
Arts building and the Riviera. ,To do this it was necessary to proceed with
' construction of as much of the westerly half of the project improvements as
possible at this time. The attached Contract Amendment No. 2 reflects the work
which was directed by the City to be undertaken in the westerly half (Phase II)
portion of the project scope. These project elements were included in the
original feasibility study and, due to the satisfactory unit Pr icess and the
timing of the project, it was deemed prudent -to expand the Shafer Contracting
contract to include this Phase IT work. . __The majority of this work is now
1 complete although no payments have been made to the coAtractoe. <:
It is therefore recommended that the attached Contract Amendment No. 2 to the
' West 78th Street North Side Public Parking Lot project'=be approved in the amount
of $117,786.80 and that a revised contract amount be established for the project
at $669,536.65. Further, the project schedule shall be extended due to the
extended scope to a November 9, 1990 cxEp1etion date.
