As part of the 2017 Water and Sewer Rate Study, renewal and replacement of the
Villages water mains, fire hydrants, valves, and other distribution system
appurtenances was identified as a high priority. One outcome of this study was an
increase in funding for water main replacement projects. A primary goal of
accelerating the pace of water main replacements is to reduce the life cycle of
water mains from an unsustainable 600 years to a more pragmatic 130 years.
2018 was the first year of an accelerated water main replacement schedule
supported by new water and sewer rates. Combined, in the first four (4) years of
this accelerated program, the Village has replaced 17,855 feet of water main and
rehabilitated an additional 6,154 feet of water main through the cured -in-place
pipe lining process.
In 2021, the water main replacement project included Wille Street, Prospect
Avenue, William Street, George Street and Connie Avenue. These sections of
water main have had multiple breaks within the last 10 years and the water main
size was increased from 6" diameter pipe to 8" diameter pipe to improve flow and
pressure.
Also in 2021, Staff rehabilitated 2,284' of existing 6" main on Can Dota Avenue,
8" main on Edward Street, See Gwun Avenue, Hi Lusi Avenue, Elmhurst Road,
Main Street, Emerson Street, School Street, William Street, Edward street, 10"
main on Emerson Street and Kenilworth Avenue and the 12" main on Prospect
Manor Avenue. These pipe segments are all crossing underneath Weller Creek and
the Union Pacific Railroad. They were all successfully rehabilitated through means
of cured -in -place -pipe lining.
In 2022, staff seeks to replace 10,923' of existing 6" and 8" water main. The
locations include Deneen! Small and Straton lane, the 1800 and 1900 blocks of
Estates Drive, Waverly Avenue from Lonnquist Blvd. to Golf Road, Audrey Lane
from Connie Lane to Bonita Avenue, Hatlen Avenue from Estates Drive to
Lonnquist Blvd., Pendleton Place from We Go Trail to Kenilworth Avenue, Waverly
Place from Pendleton place to Milburn Avenue and Cottonwood Lane from Busse
Road to Redwood Drive.
These pipe sections are scheduled for replacement due to multiple water main
breaks within the last 10 years. Plans are to abandon the existing water main in
place and installing new water main adjacent to the old one. The water main size
will also be increased from 6" to 8" to improve flow and pressure. The attached
location map depict the proposed project area.

To design these improvements, staff requires technical assistance from a qualified
civil engineering consultant. Accordingly, staff prepared a detailed request for
proposals (RFP) necessary to solicit these services. A copy of this RFP is enclosed.
Consulting engineers were asked to submit a technical proposal detailing the
firm's background, key personnel, and approach to the project. In addition, each
firm was also asked to submit a separate cost proposal indicating work effort
anticipated and a not -to -exceed fee.
The required scope of work includes topography and field data collection;
preparation of plans and bid documents; meetings and obtaining all necessary
regulatory permits.
RFPs were distributed to five (5) local engineering firms and publicized on the
Village's Demandstar website.
Ten (10) technical proposals and ten (10) cost proposals were received. Each
proposal was evaluated based on the background of the firm, related project
experience, proposed services and scope of work, schedule work effort and
proposal content. Each firm received a point ranking (total points = 100) for each
criteria. Table 1 (attached) summarized this analysis.
The highest rated firm is Thomas Engineering (Thomas) of Oak Brook, Illinois.
Thomas Engineering's proposal provided numerous examples of successful water
main replacement projects similar in scale and scope as the proposed work.
Examples cited were water main replacement projects in the City of West Chicago,
Morton Grove -Niles Water Commission, and the City of Wheaton. A copy of
Thomas' technical proposal is enclosed.
Notably, Thomas Engineering was hired by the Village of Carol Stream for Phase I,
II and III of the $3.2 million dollar water main replacement on Schmale Road. The
scope of services consisted of alternative analysis and determination of the
preferred alignment for removal and replacement of approximately 7,000 feet of
10" and 12" deteriorating water main. The work included water main
abandonment, water service line replacement, new fire hydrants, valves,
horizontal directionally drilled water main, boring and jacking, storm sewer and
sanitary sewer replacement, driveway replacement, pavement patching and
parkway restoration. Schamle Road is a four lane highway consisting of many
business and apartment complexes. Thomas Engineering procured all necessary
permits as part of the design process.
Thomas Engineering has not performed water main replacement work for the
Village of Mount Prospect in the past. However, staff contacted references from
municipalities that have contracted with Thomas Engineering on similar projects
and received positive feedback. It is the opinion of staff that Thomas Engineering
has sufficient skills, experience, and resources to successfully complete this
proposed project.
In addition to the technical proposal, each firm was also asked to submit a cost
proposal as well. Table 2 (attached) summarizes staff's analysis of these
submittals.
The lowest cost proposal was also submitted by Thomas Engineering of Oak
Brook, Illinois. A copy of the firm's cost proposal is enclosed.
It is the opinion of staff that Thomas Engineering understands the proposed
project, has prepared a thorough proposal based on extensive experience,
requested a reasonable fee, and is well qualified to perform the work. Notably, the
assigned work effort (1,334 hours) is reasonable and the requested fee ($173,904
or $130/hour) is competitive.
Staff recommends including a 10% contingency in the project award for the
proposed contract because time spent on construction engineering and inspection
can vary due to circumstances beyond the engineering consultant's control. For
example, contractor delays, material availability and inclement weather are all
parameters that can lengthen anticipated construction time. Inclusion of a 10%
contingency ($17,390.00) will increase the project award from $173,904.00 to
$191,294.00.
