BACKG ROU N D/J U STI F ICAT 10 N:
City Staff has been working to put together a comprehensive plan for the construction of the Prairie Park
Soccer Complex. The goal of this comprehensive plan was to list, in detail., the different phases of the
soccer field construction with timelines and cost associated with each phase.
Currently the project is in the planning and design phase. A survey needs to be done to have accurate
elevations to create grading plans for contractors to bid on. Construction staking during the grading
phase will be needed for the grading contractor. This cost is not included with this Request for Action
and would be dependent upon the contractor's requirements. Many contractors have GPS systerns so
only a few reference points would be required verSLIs non -GPS contractors would need quite a bit more
staking.
Thegrading is planned to take place in late June and will then allow for time for irrigation installation,
and turf establishment for fall.

RE, : Conipi,ehensive Project Costs - Soccer Fields
A more comprehensive project analysis than was provided in the 2013 CIP was requested by Parks and
Recreation Manager Ross Demant. to present to City staff and the City Council to gain authorization to
begin design of plan and specifications for the Otsego Soccer Fields project.
The project is placid to be split into several components as to have expert contractors in charge of each
element rather than have one general contractor with many subs.
Each phase of the project will have definitive time lines. Currently the only issue with the timeline is
convIeting a survey of the property to determine the actual atuount of soil that needs to be moved. The
survey needs to be completed while the ground is still frozen. April and May can be challenging to
survey an open fields due to muddy conditions. The construction of project is plamied to be split into 7
smaller phases:
1) Grading of the soccer fields — Early June
2) Installation of power by Wright Hennepin — Late June
3) Pond lining, grading of parking lots and installation of pipe from the Public Works Building to
a rnaffliole and installation of wet well — Late June
4) Installation of street lights - July
5) Installation of well VFD and appurtenances - July
6) Installation of booster station and irrigation system - July
7) Turf establislmient — August
Phase I -Soccer Field Grading
ot720 - memo - soccer fields_TPC.doc Page I of 1
CutTently, we are estimating $108,750 in construction costs for grading of the playfield area. This cost
estimate is still a very rough guess without completing a survey and coring for depth of existing topsoil
and will be fine-tuned during the grading design, which requires City Council approval to proceed with.
Plans and Specifications.
Phase 2 - Installation of Electric Service
Wright Hennepin has provided the City with a cost estimate of $2,125 for placing a transformer to supply
power for the water system, irrigation and parking lot lighting. City staff also directed that Wright
Hennepin consider future power needs for lighting of the soccer fields so that the capacity would be 'in
place if such improvements are to be made in the future.

Phase 3 —Pipe From Well to Pond/Pond Lining/Parking Lot Grading
City staff is recom-mending a single contractor perform three elements of the project having an estimated
total cost for construction of$49, 00 (including mobilization costs for all three components):
Installation of water pipe from the Public Works Building to the existing stormwater drainage
manhole adjacent to the salt storage shed and the installation of pipe and wet well adjacent to the
existing storm water pond. The piping and wet well is estimated to cost $20,000. This includes
removal and replacement of some asphalt from the building to the manhole add acent to the salt
storage shed.
Lining of the stormwater pond to retain water for storage from elevation 9 10 down to the bottom
at elevation 904 is estimated to cost $15,000 to construct. The cost of this project component may
change some dependent upon which method of lining is. Our office will be researching the
effectiveness and cost of several methods including a PVC liner, bentonite clay or use of existing
stockpiled clay. Once we have researched each of these methods and the cost assooiated with
them a recommendation will be forwarded to the council for approval as part of the Plans and
Specifications.
■ Class 5 installation and grading of the parking lots is estimated to cost $14,000. The design will
incorporate the opportunity to add additional parking to the east of the north -south drive aisle as
well as pavement, curb and gutter and storm sewer in the future. Two gates will also be installed
at the site entrance from 90"' Street and noilh end of the parking area to control access for security
purposes.
Phase 4 — Installation of Street Lights
Street lights areproposed to be located at the entrance froin 90"' Street and within the parking areas
primarily for security reasons. Wright Hennepin has provided us with a cost estimate of $13,,825 for
seven light fixtures/poles of the same type installed in the parking area east of City Hall. City staff will
work with Wright Hennepin to determine if adequate lighting can be provided with fewer fixtures.
Phase 5 - Installation of Well VFD and Appurtenances
ot720 - nienio - soccer fields—TKAoc Page 2 of 2
The test of the existing Public Works Building well has determined there is an adequate supply of water
sand free at a 100 gpm rate but controls, transducers, floats, RPZ and a VFD need to 'be installed to allow
dual usage of the well. These costs are very fluid still until more design is completed but will require
cutting into the concrete floor of the Public Works Building to gain access to the control roorn based on
the system designed by the architect. A rough estimate for construction is $37,500.
Phase 6 - Booster Station and Irrigation System
The construction costs of supplying and installing the entire irrigation system from the wet well next to
the pond to the soccer fields is estimated at $65,000. Plans and specifications for this phase will be
provided primarily by the selected irrigation contractor subject to review and approval by the City
Engineer.
Phase 7 —Turf Establishment
Parks and Recreation Manager Demant has been in contact with a set -vice professional who specializes in
athletic field turf. This turf specialist has estimated the cost for seeding and initial fertilization during the
first year to be $25,000.
Phase 8 — Engineering, Adminis traflon and Contingency
We estimate fees from our office related to preparation of plans and specifications, surveying, and
construction oversight and completing as -built plans to be $23,300.
The project estimate included with the CIP included a 20 percent contingency solne of which was to
account for engineering and administration costs that have been more specifically defined as separate line
items in this current estimate. Having refined the preliminary cost estimates for the project as outlined
herein, City staff has reduced the contingency to ten percent or $30,000.
Sunimary
The current estimate for the cost of project as outlined herein is $355,000, which is an increase of $12,700
from the amount that was presented as part of the CIP. The cost increase is due to the following:
Although the existing Public Works Building well does not require additional development to be
able to provide water to the soccer field irrigation that was included in the initial estimate,
additional work to access the well controls and make a connection to the water system for a dual
system that both supplies the Public Works building and the irrigation system are higher than
anticipated.
■ Use of the specialized professional for seeding as well as consultation on the development of the
turf is estimated to cost $103000.
■ Gates were added to secure the proposed parking lot adding $2,000 to the project cost.
