SUBJ: Award of Bids for Minnewashta Parkway Upgrade
1 Improvement Project No. 90 -15
I At their regular meeting on April 13, 1992, the City Council considered the awarding of the
Minnewashta Parkway Improvement Project No. 90 -15. As was discussed at the meeting and
in the previous staff report, one alternate was bid as a part of the project. The alternate
I bid was for the additional materials and work associated with constructing an 8 -foot trail
versus a 6 -foot trail which was specified in the base bid. The City Council tabled action on
the award to allow time to investigate the potential impacts of implementing the wider trail
I on the project. The following is a list of the pros and cons which staff is aware of for each
of the two options:
1 6-FOOT TRAIL

1 8 -FOOT TRAIL
I PROS CONS
1. Wider area for bikers and 1. Pickup plow will likely incur sod
I pedestrians sharing the use. damage to properties during the
wintertime.
2. Can be snow plowed with a pickup
I truck. 2. Additional project costs would be
incurred (approximately $40,000)
and State Aid will not pay for the
I wider section.
3. Approximately 20 additional trees
I would be lost and approximately
800 additional square feet of
retaining wall would be required.
I 4. Additional right -of -way would need
to be acquired.
I S. Residents were informed that a 6-
foot trail would be used during the
1 hearing processes.
6. Only a 2 -foot wide green space
I boulevard area would remain which
would be very difficult to keep
I alive and maintain.
Following staffs recommendation to remain with the base bid implementing the 6 -foot wide
I trail, there surfaced some allegations as to the fairness of how the bidding process was
handled by the project consultant engineer. I have discussed this matter with Bill
Engelhardt. With the size of the bids and the number of bids received, it may have taken
I some additional time to verify the bids following the bid opening. In fact, the bids were
checked and re- checked again before the confirmed low bidder information was released.
To date, I have not received any information indicating that there was any intent to
I mishandle the bidding and /or bidding tabulation process by the project consultant engineer.

The confusion occurred as a result of having one low bidder for the base bid and a different
low bidder for the alternate bid. In reviewing the two potential low bids, it is apparent that
the low base bid received from Imperial Developers had three calculation errors on bid line
items which added approximately $10,000 to their base bid. They remain the low bidder for
the base bid, however, Brown & Chris has become the low bidder for the base bid with the
alternate.
In any case, based strictly on the pros and cons impact of the trail width to the project, staff 1
continues to recommend that the 6 -foot trail be implemented. It is therefore recommended
that the base bid for the Minnewashta Parkway street and storm drainage improvement
project No. 90-15 be awarded to the low bidder, Imperial Developers, in the amount of
$1,338,534.40 contingent upon acquiring a signed cooperative agreement with the City of
Victoria and MnDOT State Aid concurrence.
