' TO: Don Ashworth, City Manager

DATE: July 20, 1995
' SUBJ: Change Order for Wetland Restoration and Trail Construction - Powers Boulevard
Reconstruction Project No. 93 -29 and Yuma Drive/ Lotus Ravine Water Quality
' Project - SWMP 12A
City Council awarded the bid for the Wetland Restoration and Trail Construction along Powers
Boulevard and the Yuma Drive/ Lotus Ravine Water Quality Project located near the northwest
' arm of Lotus Lake to Jay Bros., Inc. with the deletion of the excavation of approximately 3,500
cubic yards of wetland materials. This was done under the idea that the Park Department would
perform the excavation of materials associated with the wetland restoration and trail construction
' off of Powers Boulevard. The original bid from Jay Bros., Inc. was to excavate the materials at
$15.60 per yard. Since this bid was very high, staff attempted to do the project. In the process,
we found two park sites to haul the material to and Jay Bros., Inc. has re- evaluated their original
bid and offered a rate of $7.40 per yard. This new rate was adjusted after the haul sites were
found and they further evaluated the soils.
' ANALYSIS
Although the bids were high for this project, staff has made every effort to bring the price down
' while still maintaining efficiency and allowing the project to commence. The Park Department
had agreed to perform the excavation of the wetland; however, this would put them behind in the
' other projects they should accomplish this construction season. It seems that it would now be
worthwhile to have Jay Bros., Inc. perform the additional excavation of approximately 3,500
yards of material and transport it to the park sites under the supervision of the Park Department.
The total amount of the bid award would then be approximately $138,000, which is still about
$28,000 less than the original bid.

RECOMMENDATION
Staff recommends that the City Council approve the change order to have Jay Bros., Inc. perform
the excavation of 3,500 yards rather than the Park Department for the Wetland Restoration and
Trail Construction along Powers Boulevard and the Yuma Drive/ Lotus Ravine Water Quality
Project located near the northwest arm of Lotus Lake.

The additions, revisions and corrections contained herein shall be made to the contract documents for
the project and shall be come a part of the Scope of Work.
Description of Changes:
A. The contract is proposed to be amended to perform muck excavation necessary to construct the
wetland mitigation area. The original contract quantity for muck excavation was reduced by 3 960
cubic yards due to an unacceptably high unit bid price of $15.60 per cubic yard_ The contract
was subsequently awarded with the condition that the City Parks Department Staff would perform
the muck excavation work deleted from the contract. Based on further site investigation of the
existing soils, the Contractor has proposed to perform the muck excavation work at a unit price
of $7.40 per cubic yard_ The proposed unit price of $7.40 for muck excavation is reasonable for
the scope of work to be completed.
Incorporating the muck excavation into the contract will result in an increase in the contract
amount as :follows:
