CITY OF SHAKOPEE CONSENT
Memorandum
To: Mayor and City Council
Mark McNeill, City Administrator
From: Andrea Weber, Parks and Recreation Landscape Designer
Subject: Greenfield West Park- Change Order 2
Meeting Date: September 20, 2005
INTRODUCTION
City Council is asked to approve Change Order 2 for Greenfield West Neighborhood Park.
DISCUSSION
At the June 7, 2005 City Council meeting, Council awarded the bid for Greenfield West
Neighborhood Park and directed staff to make reductions to unit quantities in order to bring the
total construction costs within budget. Change Order # I was approved on June 21, 2005 per the
direction given by Council, with additional funding allocated from the Park Reserve fund to fund
the cost of the trees if needed.
Change Order 2 is being brought to you for approval which includes additional costs for soil
corrections required for the site amenities. Prior to construction, soil borings had been made in
several locations in the development that consistently showed high quality sand subsoils.
However, when sub soil preparation began on the site, significant amounts of clay sub soil were
discovered.
Upon this discovery, which could have been the result of soil exchange on the site, it was
determined that to ensure the long-term durability of the amenities, it would be most prudent to
replace the poor soils with clean granular material. There estimate approximately 800 cu yds of
excavation, and 531 cu yards offill material needed.
The updated project budget follows, with the full costs for staff design, construction
administration services, and the full tree plan approved by Council earlier this year. (Actual staff
design services will not be available until the completion ofthe project, but we anticipate being
under the estimate.) As directed on June 21, the remainder of the project funding would be
allocated from the Park Reserve Fund.
REOUESTED ACTION
City Council is asked to authorize, by motion, the Change Order 2 for Greenfield West Park for
$17,289 in favor ofSunram Construction.
