Council Report 97 -129
Approve Construction Change Order #1 and Authorize Additional
Engineering Fees
Lift Station No. 5 Replacement, Project #96 -02
Proposed Action.
Staff recommends adoption of the following motion: Move that Council
authorize Change Order No. 1 and authorize an additional $4,992 in
engineering fees as they relate to Lift Station No. 5 Replacement, City Project
#96 -02.
Overview.
Lametti and Sons, Inc., the successful bidder on this project, has proposed
changes to this project which reduces the construction cost by $18,520. The
consulting engineer, SEH, has reviewed the proposed changes to ensure the
project will still meet our intent and be acceptable in terms of engineering and
construction standards. The changes are based on using the existing wet well
to house the new lift station wet well and using the existing dry well area to
house a valve vault. The major benefit is due to decreased excavation and
new piping costs. The construction cost will drop from the contract amount
of $275,029 to $256,509.
The additional engineering fees were necessary to analyze the contractor's
proposal and revise the plan sheets. The engineering fee budget increases
from $43,008 to $48,000.
Staff Recommendation.
The proposed change has been reviewed and approved by the consultant
engineer and City staff. The net cost adjustments are fair and reasonable.
Staff recommends Council approval of change order and engineering fees.

RE: Hopkins, Minnesota
Lift Station No. 5 Replacement
City Project No. 96 -02
SEH No. A- HOPKN9601.00
At our request, Lametti and Sons, Incorporated, the low bidder on this project, has explored additional
ways to reduce the construction cost of this project. We have completed our discussions with Lametti
and Sons regarding an option which makes concessions on only one design criterion, that of the grade
of the driveway.
The original and alternate bids as received on May 13 met all of the City's design criteria, with the
alternate bid being chosen for project award. The revised project we have been discussing with
Lametti and Sons is generally consistent with the alternate bid, with the exception that the lift station
wet well would be constructed within the existing wet well of the existing lift station, thereby saving
on manhole, piping, and installation costs.
The control and generator building is planned to be approximately two - thirds as large as the existing
building on site. The alternate bid included reconstructing the control and generator building with the
westerly wall matching the location of the existing westerly wall. The project as now proposed by
Lametti and Sons would reconstruct the building with the easterly wall even with the easterly wall of
the existing building. This would allow for the driveway (of which there is none on the site at this
time) to be constructed on the west end of the building such that maintenance vehicles could back up
to the lift station constructed within the existing wet well.
The resulting driveway grade from Excelsior Boulevard down to the surface of the lift station is
steeper than desirable, but deemed tolerable by maintenance staff. Again, this appears to be the only
design concession necessary to capture the cost savings offered.
The specific changes to the project are documented on revised plan sheets and the enclosed change
order. The net effect is a decrease in construction cost of $18,520. This would be partially offset by
the engineering cost necessary to revise the drawings consistent with the contractor's concept for firm
pricing and construction by the contractor.

The estimated total project budget resulting from this change would be as follows:
Low bid amount
Pump package
Pump control package
Soil boring and testing
Forcemain televising
Design and construction engineering
Less MCES construction reimbursement
Less MCES engineering and administrative
Permit fees and expenses and contingencies
Total City Share
We recommend that Change Order No. 1 and the resulting project budget be approved.

of abandoning the existing forcemain on site, it shall be removed and disposed of.
6. The required period of bypass pumping will increase. The bypass operation includes resetting
the existing gravity sanitary sewer manhole cone to finish grade.
7. The doorway for the new generator and pump control building shall be on the west wall facing
the wet well.
8. The pump control panel shall be installed on the west wall on the south side of the door.
