Re: Estimate of Additional Cost to Provide Engineering Services
East River Interceptor and Watermain Replacement
Bonestroo Project No. 77-05109-0
Dear Jeff:
According to our Agreement for Professional Services within the City of Shakopee and Section I-C-2
(Major PfOjects), this extension agreement is written to provide you with an estimate of cost for
engineering services for the above-referenced project. We are proposing to complete the work as detailed
in the attached scope of services, Exhibit A.
As discussed at recent meetings, Scott County is planning to reconstruct County State Aid Highway
(CSAH) 101 from the east side of Marschall Road (CSAH 17) to 1,300 feet east of CSAH 17 in 2006.
The City of Shakopee and Shakopee Public Utilities Commission are proposing to replace ex.isting
utilities in this corridor, and the City is also looking at incorporating interceptor improvements adjacent to
this project.
The City Staff and our office have been working with the County in relation to the East River Interceptor
Replacement due to the poor condition of the existing sanitary sewer in this area and its location under
existing mobile homes. The City had previously authorized us to proceed with design of a partial
replacement of this interceptor as part of the West River Interceptor Improvements due to maintenance
concerns with the existing sewer line.. Three alternatives were reviewed along with preliminary designs in
2004. Atthat time and since the County had not yet identified a scope of improvements along CSAH
101, the initial interceptor improvements would have resulted in the City paying for removal and
restoration of portions of CSAH 10 I as well as other associated costs.
Byreplacing aging utility infrastructure in conjunction with the CSAH 101 Project, the City will reduce
costs associated with removal and restoration of CSAH JO I. The City will also reduce their risk for
emergency repairs and traffic disruptions in the future in this corridor. Approximately 1,200 feet of
sanitary sewer replacement is proposed to be added to the previously proposed 900 feet of replacement.
Also, approximately 1,050 feet of watermain replacement is being proposed to be added to the project
These utilities would be included in the County project.
Our previous engineering agreement with the City of Shakopee does not include the design of this
additional sanitary sewer or watermain replacement. Also, various easement acquisition, permits, and
additional coordination with SPUC, Scott County, and MNDOT State Aid were not part of the previous
agreement. The attached Work Plan describes the approach and tasks proposed to be completed by
Bonestroo, Rosene, Anderlik and Associates, Inc. (Bonestroo).
We estimate the additional fee to complete the design will be $30,000 and a fee not to exceed $35,000.

Both of these fees include $3,000 allowance for soils work along the interceptor route to the south of
CSAH 101 as well as additional field survey, preparing permits, preparing easements, easement
acquisition, and coordination with SPUC, Scott County, and MNDOT State Aid. We will review our
progress monthly and will not exceed this amount without your prior approval.
We can continue work on the additional utilities as soon as authorized by the City and complete the
project according to Scott County's preliminary schedule of bidding the project in Winter 2006. If you
have any questions regarding this submittal, please feel free to call me at (651) 604-4829.
The City of Shakopee agrees to reimburse Bonestroo for these services in accordance with Section 4 of
the agreement for professional services. If this agreement meets with your approval, please sign below
and return one copy to our office^
Sincerely,
BONESTROO, ROSENE, ANDERLIK & ASSOCIATES. INC.

Description of the Proiect
Scott County is planning to reconstruct County State Aid Highway (CSAH) 101 from the east
side of Marschall Road (CSAH 17) to 1,300 feet east of CSAH 17 in 2006. The City of
Shakopee and Shakopee Public Utilities Commission are proposing to replace existing utilities in
this corridor, and the City is also looking at incorporating interceptor improvements adjacent to
this project both to the north and south side of CSAH 101. The north side would relocate the
sanitary sewer from under existing mobile hames and the south side would replace the sanitary
sewer at or near the existing sanitary sewer from the north side 'Of the existing railroad tracks to
CSAH 101. The sanitary sewer and watermain will be placed in the same trench as the existing
utilities in CSAH 101.
Design Flow
Bonestroo will revisit the design flow projections in the City's Comprehensive Sewer Plan as
well as discuss with recent staff review to confirm the proper capacity and size of the
replacement interceptor,
Interceptor Replacement
Aportion of the replacement interceptor will be constructed adjacent to the MCES forcemain on
the north side of CSAH 101 and west of the Mobile Home Park. MCES has requested that a
temporary forcemain be set up during construction. Rock ex.cavation will be needed based on
existing boring information in this area.
A sewer line will be placed along the north side of the Mobile Home Park to the location of the
existing manhole to pick up the commercial properties to the east. The sewer line in CSAH 101
will. be located in the same trench as the existing sanitary sewer and watermain to minimize rock
excavation in this area. Final alignment of the sewer line between CSAH 10 1 and the north side
of the existing tracks will be finalized with the plans.
The existing sanitary piping will be replaced with SDR 26 pipe based on previous discussions
with CityStaff. Sanitary sewer pipe placed in the same trench as watermain generally needs to
be a C900 PVC (or DR 18) or equivalent material. Bonestroo will coordinate with Scott County
on placing new rim elevations to match their new roadway design and profile.
Continuous sanitary sewer service must be provided by the sanitary replacement. An obvious
goal of the prqject should be to keep the existing interceptor in operation until the replacement
interceptor can be placed in service. However, due to site constraints along the alignment in
CSAH 10 1, it will be necessary to take portions of the ex.isting interceptor out of service to
permit construction of the replacement interceptor,. Bonestroo will evaluate the required
construction sequencing during design. Temporary pumping and temporary connections will be
specified and detailed, as necessary.
Sanitary Sewer Services
Active sanitary sewer laterals will be reconnected to the new sewer line. Bonestroo will review
with City Staff any inactive laterals that may exist and determine how these will be abandoned or
reconnected with the project. Bonestroo will prepare specifications, drawings, and details for
disconnecting these services from the existing interceptor and reconnecting them to the
replacement interceptor.
Storm Sewer
Storm sewer will be designed by Scott County and reviewed by City Staff. Bonestroo will
collect this design information from the County and indicate storm sewer pipe and structures,
crossing elevations, and pipe size information on the sewer and water plan sets to be inserted in
the County Plan Set.
Watermain
Bonestroo will show replacement of the existing watermain in the same trench as the sanitary
sewer in the CSAH 10 1 corridor as per Shakopee Public Utility Commission (SPUC) direction
and specifications.. Bonestroo will review with SPUC any inactive services that may exist and
determine how these will be abandoned or reconnected with the project. Bonestroo will also
review with SPUC the acceptable downtime for water service in the area and address in the plans
and specifications. Bonestroo will prepare and reference existing specifications, drawings, and
details for the prqject as well as prepare contract documents for disconnecting inactive services
from the existing watermain or reconnecting them to the replacement watermain. Active existing
services will be reconnected to the new main.
Plan Review Meetin~s
Bonestroo will schedule review meetings with the City of Shakopee, SPUC, and Scott County
and prepare minutes of meeting discussions. OUf fee is based upon three (3) review meetings
with each group.
Easements
Drawings will be prepared showing the permanent and temporary easement areas that the
contractor may utilize during construction as part of the plan set. Easement
descriptions/drawings and acquisition will be included in our fee. The fee is based upon two (2)
meetings with four (4) agencies or property owners including the owner of the Shakopee Valley
RV Park, MCES, the owner of the parcels to the west of the mobile home park, and the owner of
the parcels adjacent to the existing sewer line south of CSAH 101 and north of the existing
railroad. Any appraisals and recording of the easements will be by others..
Final Design
This phase will include the development of bidding documents as necessary to facilitate
construction, as well as receive the necessary agency approvals. Preparation of these documents
includes, but is not limited to, the following tasks:
- Existing utilities and removal plans for sanitary sewer outside of the CSAH 101
ROW to insert in County plan set (State Aid format)
- General details and construction notes
- Erosion control/landscaping in areas outside of CSAH 10 1
- Construction staging of sanitary sewer and water replacement
- Interceptor Sanitary Sewer plans in CSAH 101 and defined areas to the north and
south
- Watermain plans in CSAH 101
- Sanitary sewer service plans to insert in County plan set (State Aid format)
- Water service plans to insert in County plan set (State Aid format)
- Restoration plans (outside of CSAH 101 ROW) to inselt in County plan set (State
Aid format)
- Specifications for sanitary sewer, watermain, and any restoration not covered in
the County work
- Quantitiesto insert in County plan set (State Aid format) and bidding documents
- Bonestroo will utilize the standard City of Shakopee and SPUC specifications and
details a. Project-specific items will be addressed in a special provisions section,
as well as a supplementary general condition section.
Permits
Bonestroo will prepare permits to the MPCA (Sanitary), Minnesota Department of Health
(MDH) (Water) , Scott County (Utility work in ROW), MCES (work in easement area), and
possibly Railroad Permits if work is done in rajlroacl right of way in connecting to the manhole
to the north of the railroad.
