andWork Task Detail
RECOMMENDED ACTION: Motion to Authorize Engineering Services for Trunk Watermain
in Coordination with Dakota County TH 52 and CSAH 42 Interchange Project, County
Project No. 42-82, City Project 461
BACKGROUND
At the April 19, 2016 meeting of the Rosemount City Council, the Council approved of a resolution to
order the installation of trunk watermain along the length of the CSAH 42 with the improvements to be
constructed with theTH52/CSAH42 Interchange project. Staff has requested and received a proposal
from SRF Consulting Group, Inc., to carry out the design of the trunk watermain and include the
watermain within the bid documents for the52/42 project. SRF is Dakota County’s primary engineering
consultant responsible for the design of the 52/42 project.
The proposal received from SRF offers to provide project management, design, permitting and bidding
services at an estimated fee of $49,034.38. The SRF fee for professional services is approximately 7% of
the preliminary estimated $698,000 construction cost for the installation of the 16” trunk line along the
extents of the CSAH 42 improvements. The proposed SRF fee is within the guidelines of Manual 45
published by the American Society of Civil Engineers (ASCE) and other professional engineering agencies
for a project of this complexity.
Staff is recommending execution of a contract with SRF to proceed with the design and bidding of the
Rosemount trunk water main. The fee is within the range of that to be expected with this type of project
and the utilization for the prime design engineer for the overall project will help to insure a seamless
installation.
SUMMARY
Staff recommends that the City Council authorize a contract with SRF Consulting Group, Inc. for
Professional Services for Watermain Design and Bidding services for the installation of Trunk Watermain
in coordination with the Dakota County Project to Reconstruct the Interchange at TH 52 and CSAH 42,
Dakota County Project No. 42-82, City of Rosemount Project 461.

SUBJECT: P ROPOSAL FOR P ROFESSIONAL S ERVICES FOR W ATERMAIN R EPLACEMENT,
I N C ONJUNCTION WITH TH 52 AND CSAH 42 I NTERCHANGE
Dear Mr. Wrase:
SRF Consulting Group, Inc. (SRF) is pleased to provide this proposal for final design services for
watermain replacement in conjunction with the TH 52 and CSAH 42 Interchange project. We
appreciate the opportunity to serve the City of Rosemount to complete this project.
SCOPE OF SERVICES
The Scope of Services includes project management, data collection and final design, specifications,
preparation of final construction plans, tabulations of proposed watermain improvements, and an
construction documents will be prepared
consistent with that required for a City of Rosemount project as appropriate and incorporated into
the Dakota County roadway project.
The project consists of the following elements:
Coordination, analysis, and replacement of the City-owned watermain within the interchange
project area.
Our understanding of the work involved in watermain replacement includes the following:
County Road 42 (approximately 5,400 feet, from 1,600 feet west of TH 52 to 3,800 feet
east of TH 52). New 16-inch DIP pipe was requested to be installed for the entire length
of CSAH 42.
Connections to the existing looped distribution system will be required at various
branches, along with any services and the reconnections with the original pipe on either
end.
It is assumed that casings will be required when crossing CSAH 42 and interchange ramp
locations. These crossing may need to be jacked.
Mr. Patrick Wrase, PE - 2 - March 23, 2016
City of Rosemount
Watermain construction plans, general conditions, and special provisions are to be included in the
Dakota County TH 52 and CSAH 42 Interchange project bid.
Coordination of design details and schedule with the Dakota County TH 52 and CSAH 42
Interchange project.
We have attached a detailed scope and task item breakdown for our specific budget and fee, which
includes the following items:
1)Meetings Meetings with City staff via conference call or "GoToMeeting" during the design
process, as needed. Attend Dakota County PMT meetings as needed to coordinate watermain
design with the roadway project.
2)Construction plans will be submitted for review at final design (60 percent and 100 percent) stages.
The plans will meet both Rosemount design criteria and MnDOT/Dakota County format. The
project schedule and staging plan will be incorporated within the overall TH 52 and CSAH 42
Interchange project design and delivery schedule. Preliminary and of
Probable Construction Cost will be prepared.
3)SRF will prepare complete bidding documents in MnDOT/Dakota County format (both special
provisions and general conditions, along with complete construction plans). It is assumed that
the watermain replacement scope of this contract will be bid with the larger TH 52 and CSAH 42
Interchange project. This scope includes assistance from SRF staff in answering bidding
questions.
PROJECT TEAM
The Project Manager will be Steven Miller, PE (MN), Senior Associate, with advisory assistance from,
Dave Nelson, PE, Principal. Steve has extensive experience with municipal services and utility work.
Our design team is prepared to deliver this project within the same schedule as the TH 52 and CSAH
42 Interchange project.
