CONSIDER APPROVAL OF CHANGE ORDER NO. 1 TO
THE CONTRACT FOR CONSTRUCTION OF PIKE LAKE
TRAIL TO ELIMINATE A RETAINING WALL.
MARCH 16, 1998

SUBJECT:
BACKGROUND:
The improvement of Pike Lake Trail was in the 1997 C.I.P.
(Capital Improvement Program). Plans and specifications
were prepared and bids were opened on August 4, 1997.
As part of the design a retaining wall was required on the
west side of Pike Lake Trail.
After construction began Herb Wensmann. owner of both
parcels on the west side of Pike Lake Trail. approached the
City with draft plans to develop one site on the southerly
most part of the property and requested an access directly
to Pike Lake Trail for this site. The engineering staff met with
Wensmann and his engineer to discuss this concept. He can
pursue building on this site with a building permit. Further
development of the parcel would require platting. Pike Lake
Trail is a Minor Collector, and the request for an access at
the proposed location is consistent with a Minor Collector.
Due to the topography of the site an access at the requested
location required significant fill. Wensmann offered the use
of material from his parcel. With placement of the fill the
need for a retaining wall as contemplated in the approved
project plans to support Pike Lake Trail was eliminated. The
need for a guard rail was eliminated as well.
By the time Wensmann brought his request to the City the
retaining wall sub-contractor had incurred costs of
engineering, mobilization, and freight. Additionally, he
incurred a re-stocking charge to return the blocks. The utility
sub-contractor incurred a re-mobilization cost to return to the

project and make required watermain modifications to
accomodate the slope vs. retaining wall. This project was
assessed to abutting properties and Wensmann was
assessed $187,612 for street costs.
Included with this change order is the cost for the utility sub-
contractor to provide a water service stub to one of the
parcels in the Maple Hill Plat. This water service was not
originally contemplated in this contract but the homeowner
requested it during construction. The property was
assessed for water, thus recovering this cost for the City.
The change in contract cost is summarized on the attached
sheet and totals a deduction of $72,632.
There are two alternatives for the City Council to consider:
1. Approve Change Order NO.1 to Pike Lake Trail to
eliminate a retaining wall.
2. Deny this item and provide staff with direction.
On October 13, 1997, the City Council reviewed and
concurred with this change at a work session with the formal
change order to be presented at a later date once final
costs/deductions were determined. The contractor has
finalized his costs and a formal change order is attached for
Council approval.
Alternative No. 1
Motion and second to pprove recommended alternative.
