DATE: APRIL 25, 2011
SUBJ: BID RESULTS FOR 2011 CDBG PROJECT — BASIN 37 SANITARY SEWER
REPAIRS, LAKE BRIARWOOD SUBDIVISION ($797,285.00)
BACKGROUND
In response to resident complaints in the Lake Briarwood (Basin 37) area about basement
backups and grease blockages, Public Works retained the professional services of Baxter &
Woodman Consulting Engineers of Crystal Lake, Illinois to perform a Sanitary Sewer Evaluation
Study (SSES) and to prepare engineering plans and specifications for rehabilitation work on
Village -owned sewer facilities that service the area. The overall repair effort is comprised of
both public and private sewer repairs with the public repairs split into two (2) Phases. As part of
the bid, there is an option to bid both phases together as one project and Baxter & Woodman
has estimated that there is a potential for savings for the Village in this present economy.
The following repairs of the existing public portion of sanitary sewer system were included in the
bid:
Phase 1
a. Replace approximately 720 feet of sewer near the north ends of Briarwood Drive East
and West
b. Replace approximately 940 feet of sewer generally located along Lynn Court
Rehabilitate approximately 790 feet of sewer along Briarwood Drive East using cured -in-
place pipe (CIPP) to eliminate pipe defects
Revised Cost Estimate for Phase 1 - $689,000
Phase 2
Replace approximately 900 feet of sewer along Briarwood Drive East
Revised Cost Estimate for Phase 2 - $185,000
TOTAL ENGINEER'S COST ESTIMATE PHASE 1 & 2 - $874,000
ENGINEER'S COMBINED PROJECT ESTIMATE (including discount) $851,000
To assist with funding the project, Public Works obtained a $60,000 grant under the Community
Development Block Grant program. The use of the federal grant will require the contractor to
adhere to the federal program reporting rules and requirements.
Additional funds necessary to facilitate completion of both phases (Phase I and Phase II) as a
single project were made available by amending the 2011 budget to include unexpended sewer
improvement funds from the 2010 budget.

BID ESULTS FOR 2011 CDBG PROJECT -BASIN 37 SANITARY SEWER REPAIRS, LAKE BRIARWOOD SUBDIVISION ($797,285.00)
April 25, 2011
Baxter & Woodman prepared the plans and specifications for the repairs to the public portion of
the sanitary sewer system within Basin 37 which is comprised mostly of the Lake Briarwood
Subdivision and multi - family developments to the north and east of the Briarwood area. The bid
requested that each contractor provide pricing for each of the two separate phases and also, a
combined price for all of the work.
BID RESULTS
Prior to the bid opening, five (5) bids were distributed to area contractors experienced in sewer
construction. In addition, public notice was posted in a local newspaper as required. A total of
ten (10) bidders picked up plans and specifications for the project. Sealed bids were received
until 1:00 p.m. on Monday, April 25, 2011 at which time they were opened and read aloud. Five
(5) bids were received. The bid results are as follows:

$295,938.00
$971,280.00
Construction, Prairie Grove, IL
DISCUSSION
Staff has evaluated all bids and determined that all bids received are responsive to the request.
All bidders submitted the required bid bonds and appropriate references. The apparent low
bidder for the proposed 2011 CDBG — Basin 37 Sanitary Sewer repairs is Swallow Construction
of Downer's Grove, Illinois. They have met all the bid requirements and submitted the required
bid bond. Swallow Construction has not worked for the Village in the past. Area references
were contacted and all had good remarks for the company. The engineer estimated that the
cost of the repairs for both phases of the project is $851,000.
Since three (3) of the five (5) bids received were lower than the engineer's estimate for the
complete project, and the fact that sufficient funding is available in the current budget, staff and
the engineer are recommending that the Board award the entire project as one combined
project. Completing the recommended work as a single project will facilitate full realization of
the improvements and minimize disruption and inconvenience for the impacted neighborhood.

April 25, 2011
Staff recommends the inclusion of a contingency in the award for this proposed contract due to
the fact that the bid quantities are estimates and actual field measurements will vary. In this
instance, staff is recommending a 10% contingency to the contract award in the amount of
$72,480.50. The total recommended award would be $797,285.00 ($724,804.50 for the base
award plus a contingency of $72,480.50).
RECOMMENDATION
I recommend awarding a contract for the 2011 CDBG PROJECT — BASIN 37 SANITARY
SEWER REPAIRS, LAKE BRIARWOOD SUBDIVISION to Swallow Construction of Downer's
Grove, Illinois in an amount not to exceed $797,285.00. Sufficient funds for this proposed
contract exist in the current budget. Funding for this proposed project will come from the water
and sewer enterprise fund.

SUBJ: PROFESSIONAL SERVICES AGREEMENT FOR ENGINEERING
ASSISTANCE WITH SANITARY SEWER REPAIRS IN BASIN 37-
LAKE BRIARWOOD SUBDIVISION ($67,000)
BACKGROUND
In response to resident complaints in the Lake Briarwood (Basin 37) area about basement
backups and grease blockages, Public Works retained the professional services of Baxter &
Woodman, Consulting Engineers of Crystal Lake, Illinois to perform a Sanitary Sewer
Evaluation Study (SSES) and to prepare engineering plans and specifications for rehabilitation
work on Village -owned sewer facilities that service the area. The overall repair effort is
comprised of both public and private sewer repairs with the public repairs split into two (2)
phases. As part of the bid, there is an option to bid both phases together as one project and
Baxter & Woodman has estimated that there is a potential for savings for the Village in this
present economy.
DISCUSSION
Staff reviewed the needed work to determine whether there was an opportunity to receive
multiple proposals from area firms to provide construction engineering assistance to the Village
during the recommended improvements. Baxter & Woodman is familiar with the Village's
sanitary sewer system in that they have several years experience working with village staff and
residents in evaluating our sanitary sewers. In addition, Baxter & Woodman has intimate
knowledge of this particular basin in that they performed the sanitary sewer evaluation study,
attended the various Board and resident meetings to hear the concerns of the neighborhood,
and they have also prepared the plans and specifications for the improvements being pursued.
Staff asked Baxter & Woodman to prepare a proposal for professional engineering services to
provide specified construction engineering services for the Basin 37 Lake Briarwood Sanitary
Sewer Improvements. Baxter & Woodman initially proposed a total fee of $71,500.00 to assist
for Phase 1 and Phase 2 of the project. Staff went back to Baxter & Woodman and asked if
there were any cost savings opportunities available. Baxter & Woodman offered a savings if the
Village combined the two engineering assistance agreements into one agreement. The Village
will save $4,500 by combining this work. Typically, total fees of 8 to 10% for engineering
assistance and construction monitoring are expected. The total fee of $67,000 being proposed
is 8.4 % of the actual bid award for the complete project.
Due to their exemplary performance record on Village projects, and intimate knowledge of the
Lake Briarwood sanitary sewer system, it is the opinion of staff that the best interests of the
Page 2 of 2

April 26, 2011
Village would be served by retaining Baxter & Woodman to provide specified construction
engineering services for the Basin 37 Lake Briarwood Sanitary Sewer Improvements Phase I
and II.
RECOMMENDATION
I recommend that the Village Board authorize a professional engineering services agreement
with Baxter & Woodman, Consulting Engineers of Crystal Lake, Illinois for specified construction
engineering services associated with the Basin 37 Lake Briarwood Sanitary Sewer
Improvements Phase I and II in an amount not to exceed $67,000. Sufficient funds for this
proposed agreement exist in the current budget. Funding for this proposed contract will come
from the water and sewer enterprise fund.

SUBJ: BID RESULTS FOR SEWER REPAIRS USING CURED -IN- PLACE -PIPE
(CIPP) PROCESS ($546,572.81)
Background
In the current budget, staff requested funds to continue the combined sewer system repairs.
These repairs were identified during the Combined Sewer System Evaluation Study (CSSES)
completed in 2004. In total, almost $15 million worth of repair work has been slated.
This work primarily consists of rehabilitating existing sewer main pipes using a no -dig, cured -in-
place- piping (CIPP) process. To facilitate this work, staff prepared two (2) separate bid
packages. One package was designed to solicit contractors for rehabilitating sewer mains using
the CIPP process. The other bid package was drafted to procure the services of a sewer
excavation contractor capable of replacing structurally failed pipe (spot relays). The defects
were ranked in the CSSES in categories from 5 being the worst to 1 being minimal to no repairs
being needed. Both of these bid packages are oriented towards repairing a few remaining
Category 4 defects and many of the Category 3 pipe defects identified in the CSSES. The
worst defects noted in Categories 5 and 4 have been repaired in prior years work.
The rehabilitation work performed since 2005 resulted in the elimination of all the worst defects
(Category 5) and will address 100% of the Category 4 with the successful completion of this
year's efforts. In addition, approximately 10% of the Category 3 and 2 defects in our combined
sewer system have been completed to date.
Also, each year the Village also repairs a portion of the separate sanitary sewer system. This
work in the separate sewer system also utilizes the CIPP process. This separate sanitary sewer
work has also been included in these bid packages. Distinct funds were appropriated in the
current budget for these improvements.
As was done last year, the bid will allowed contractors to propose either steam or hot water
curing of the lining for certain diameters of pipe. This change has resulted in a per foot cost
savings as additional footage can be lined with this improvement in technology.
This memorandum presents the results of the bids for the CIPP work only. Bid results for spot
relays will be presented via a separate document. The locations of the work planned for the
Page 2 of 3

USING CURED -IN -PLACE -PIPE (CIPP) PROCESS ($546,572.81)
April 28, 2011
proposed CIPP award is outlined in Attachment A. This year's proposed project features 14,558
lineal feet of lining work in pipes ranging from 8" to 30" in diameter.
Bid Results
Prior to letting, four (4) invitational bids were distributed to contractors experienced in the CIPP
process. Public notice was posted in a local newspaper as required. A total of four (4) bid sets
were released to contractors. Sealed bids were received until 1:00 P.M. on Monday, April 25,
2011 at which time they were opened and read aloud. Three (3) bids were received. The bid
results are as follows:

$ 536,433.20
Michels Lining of Brownsville, WI
$ 1,335,756.00
American Pipeliners of West Chicago, IL
No Bid
Discussion
Staff has evaluated all bids and determined that the bids received are responsive to the request.
All bidders submitted the required bid securities and appropriate references. All of the
submitted bids are compliant with the bid specifications in all aspects and all are an authorized
licensee of an acceptable CIPP system.
Visu -Sewer of Illinois, LLC of Bridgeview, IL is the apparent low bidder and provided all the
necessary material and reference as outlined in the bid specification. Visu -Sewer has done work
for the Village in the past and their work has been satisfactory and timely. Over the last 20
years, Visu -Sewer has satisfactorily completed several CIPP installations in our Village.
Staff is recommending that an estimated 5% contingency ($22,000) be added to the contract. A
contingency would cover the difference between actual lineal footages and the estimates used
to prepare the bid specifications, address unforeseen sewer services that would need to be
reinstated and make any other small repairs needed to be performed prior to the lining of the
sewer. The contingency would raise the total project cost to $546,572.81) ($524,572.81 base
bid plus the contingency of $22,000).

DATE: APRIL 28, 2011
SUBJ: BID RESULTS FOR 2011 SEWER LINE SPOT RELAYS ($235,095.30)
BACKGROUND
In the current budget, staff requested funds to continue the combined sewer system repairs.
These repairs were identified during the Combined Sewer System Evaluation Study (CSSES)
completed in 2004. In total, almost $15 million worth of repair work has been slated.
Some sewer pipe segments have significant structural defects that can only be effectively
repaired by excavating and replacing segments of sewer main (spot relays). The majority of the
sewer rehabilitation is being performed using the cured -in- place -pipe (CIPP) process.
To facilitate this work in 2011, staff prepared two (2) separate bid packages: one package for
sewer repairs using cured -in -place piping (CIPP) and another for sewer repairs requiring
excavation and pipe replacement (spot relays).
The sewer line spot relay bid package was drafted to procure the services of a sewer
excavation contractor capable of replacing structurally failed pipe and installing or repairing
manholes. This proposed work, along with the spot relay rehabilitation work performed since
2005, has eliminated the worst combined sewer defects (Category 5) and addresses the
remaining Category 4 and Category 3 defects requiring excavation and pipe replacement.
Each year the Village also rehabilitates the separate sanitary sewer system using the same
contract and specifications. This proposed work is comprised of both spot relays and cured -in-
place -pipe lining. This work is included in the appropriate bid package (CIPP or spot relay) and
distinct funds are utilized to pay for these improvements.
This memorandum will present the results of bids for spot relay work only. Bid results for the
CIPP will be presented via a separate document. The locations of the work planned for the
proposed Sewer Line Spot Relays award is outlined in Attachment A. This year's proposed
project features (23) point repairs and (5) new or replacement manholes.

BID RESULTS
Prior to letting, seven (7) bids were distributed to area contractors experienced in sewer
construction. In addition, public notice was posted in a local newspaper as required. Five (5)
additional contractors picked up plans and specifications for the project. A mandatory pre -bid
conference was held on April 19, 2011 to allow for questions on the plans and project. Sealed
bids were received until 1:00 P.M. on Monday, April 25, 2011 at which time they were opened
and read aloud. Four (4) bids were received. The bid results are as follows:

$229,679.18
Suburban General Construction, La Grange Park, IL
$231,160.00
LIFCO Construction, East Dundee, IL
$240,400.00
DISCUSSION
Staff has evaluated all bids and determined that all bids received are responsive to the request.
All bidders submitted the required bid bonds and appropriate references. The apparent low
bidder for the proposed spot relay work is Martam Construction of Elgin Illinois. Martam
Construction is a very well known contractor and has worked on numerous Village projects in
the past. They have met all the bid requirements and submitted the required bid bonds. Area
references were contacted and all had good remarks for the company. Previous work for the
Village has been timely, without issue and of high quality. Staff's estimated that the cost of the
repairs for 2011 was approximately $200,000.
Staff recommends the inclusion of a contingency in the award for this proposed contract due to
the fact that the bid quantities are estimates and actual field measurements will vary. Also,
during each year of the project, there have been 2 to 3 additional spot relays discovered during
the CIPP process. The average cost per additional dig can be up to $10,000 and having a
contingency would allow some additional work if needed. In this instance, staff is
recommending a 10% contingency to the contract award in the amount of $21,372.30. The total
recommended award would be $235,095.30 ($213,723.00 base award plus a 10% contingency
of $21,372.30).

FROM: WATER /SEWER SUPERINTENDENT
DATE: APRIL 28, 2011
SUBJ: ENGINEERING SERVICES AGREEMENT FOR CURED -IN- PLACE -PIPE
(CIPP) AND SEWER LINE SPOT RELAY PROJECTS ($80,385)
BACKGROUND
In the current budget, staff requested funds for continuing the combined and separate sewer
system repairs. The combined sewer repairs were identified during the Combined Sewer
System Evaluation Study ( CSSES) completed in 2004. In total, almost $15 million worth of
combined sewer repair work has been slated over fifteen years. This year is the 7th year of the
project.
Due to the scale of this project, literally a multi - million dollar, multi -year effort, staff is
recommending the use of an engineering consultant part -time to assist Village staff in the
oversight of this program. The program for 2011 includes 14,558 lineal feet of cured- in- place-
piping (CIPP), 23 spot relays, and 5 manhole replacements.
DISCUSSION
Baxter & Woodman, Consulting Engineers of Crystal Lake, Illinois prepared the initial CSSES
study that provided the Village with detailed information about the condition of the Village's
combined sanitary sewer system. The firm is very familiar with the Village's infrastructure
rehabilitation program and is well attuned to our customer oriented work philosophies. In
addition, Baxter & Woodman has successfully provided construction engineering services for
each of the 6 annual CIPP and spot relay projects completed to date. All of these projects have
been completed on schedule and under budget.
The CIPP and spot relay programs continue to be substantial and demanding as in previous
years. It is the opinion of staff that the best interests of the Village would be served by the
continued use of Baxter & Woodman on a part -time basis to provide engineering oversight on
these programs.
Mount Prospect Public Works Department
At staff's request, Baxter & Woodman submitted a proposal to supply limited engineering
assistance after contract award that includes half -time oversight of the CIPP project, 100%
construction observation of the spot relay work, and overall contract administration for both
projects.
Page 2 of 2
Engineering Services Agreement for Cured -In -Place -Pipe (CIPP) and Sewer Line Spot Relay Projects
($80,385)
April 28, 2011
Their fee to assist the Village with both of these projects for 2011 amounts to a not to exceed
total of $80,385. The amount paid to Baxter & Woodman in 2010 for this effort was $96,000.
The proposed work in 2011 has 9 more spot relays than performed in 2010 but the CIPP lining
project has 20 less CIPP liner segments than last year. Baxter & Woodman has reduced their
2011 fee request accordingly.
Engineering services for this type of work usually range between 8 -10% of the overall project
costs. When the fee is compared to the actual bids received, the fee is 10% of the proposed
award amounts of $769,168.11. As this is a not to exceed proposal, the fee will vary with the
actual project costs but not exceed the $80,385.
RECOMMENDATION
I recommend that the Village Board authorize a contract with Baxter & Woodman Consulting
Engineers of Crystal Lake, Illinois for specified engineering services associated with the Sewer
Line Spot Relay Repairs and the Sewer Rehabilitation using CIPP Process projects in an
amount not to exceed $80,385. Sufficient funds for this proposed contract exist in the current
budget. Funding for this proposed project will come from water and sewer enterprise funds.

FROM: VILLAGE ENGINEER
DATE: MAY 12, 2011
SUBJECT: 2011 POND REHABILITATION PROJECTS
KENSINGTON BUSINESS CENTER —
POND #4 ENGINEERING DESIGN RECOMMENDATION - $19,687
POND #5A INSPECTION RECOMMENDATION - $8,363
Backjzr
As part of the Kensington Business Center development in the 1980's, the annexation agreement
requires the Village to maintain certain aspects of the 11 retention basins within the park. While
the park's management company provides routine maintenance such as algae removal, the
Village is responsible for dredging work so that the water depth of the ponds conforms to the
design requirements. In addition, the Village maintains and repairs the inflow and outflow
structures in each of the ponds and provides bank stabilization.
In 1998 a comprehensive study of the condition of all the ponds was completed, in part to
identify needed repairs and establish a priority ranking for these repairs. In 2002, 2006, and
2008, the Village rehabilitated ponds #4A, #3 and #7, respectively. The Village Board awarded
contracts for design and construction engineering for each pond to Ciorba Group Inc. ( Ciorba).
The next ponds on the priority list are ponds #5A and #4. The ponds, shown on the attached
map, are at the northwest corner of Business Center Drive and Feehanville Drive. Funds have
been allocated for the design and construction engineering and construction of Pond 5A and for
design engineering for Pond 4.
Discussion — Pond #5A Construction Engineering
The Village Board awarded a contract to Ciorba for design engineering for Pond #5A. The
design has been completed and the project will be let out for bids soon. Village Staff will
provide daily construction inspection but specialized layout, surveying and quantity verification
will be needed. In order to provide a timely and inexpensive transition, staff proposes to use
Ciorba to provide limited but necessary construction engineering services.
Village Staff requested a fee proposal for construction engineering services from Ciorba. Their
fee proposal was closely scrutinized in terms of both proposed staff hours and prices compared
to previous similar projects.
The fee proposal is $8,363.00.
2011 Pond Rehabilitation Projects
May 12, 2011
Discussion— Pond #4 Engineering Design Proposal
As permitted by the Qualification Based Selection process, the Village solicited a proposal for
engineering services for the design of the Retention Basin Dredging Project Pond #4 from a
qualified engineering firm Ciorba, with which the Village has prior experience. Ciorba has
previously completed engineering services for retention basin dredging projects for the Village.
In addition, Ciorba has also provided services for the Village on street light, traffic signal and
bridge rehabilitation projects. With each of these projects in the Village, their work has been
acceptable. Ciorba was asked to submit as part of their proposal the following information:
1. A summary of the firms approach to the project.
2. A staff hour estimate for major phases of work.
3. A maximum, not -to- exceed fee for design of the project.
4. A project schedule.
Tasks that were identified to be performed included:
1. Topographic survey
2. Preliminary design
3. Final plan preparation
4. Bidding assistance
5. Attending meetings
6. Obtain necessary permits from the Army Corps of Engineers, Metropolitan Water
Reclamation District of Greater Chicago, and the North Cook County Soil and Water
Conservation District.
Ciorba's proposal depicts a clear understanding of the dredging project's goals and their
methodology of the design process. Their fee proposal was closely scrutinized in terms of both
proposed staff hours and prices compared to previous similar projects.
This contract is for design services only. Once the project is ready to go to construction, it is
anticipated that a separate construction engineering contract will come before the Village Board
of Trustees for approval. It is difficult, however, at this point to determine the amount of a
construction engineering contract until the project's scope is refined and the design is complete.
Should the consultant meet the Village's expectations during the design phase, we plan to
negotiate a construction engineering contract with the same company. This will allow for a
smooth transition into the construction phase and enable the field personnel to work closely with
their own design team.
The fee proposal is $19,687.00.

2011 Pond Rehabilitation Projects
May 12, 2011
Recommendation
It is Staff's recommendation that the Village Board award a contract to Ciorba Group, Inc. for
construction engineering services of Pond #5a for a not to exceed amount of $8,363.00.
It is also Staff's recommendation that the Village Board award a contract to Ciorba Group, Inc.
for engineering design of Pond #4 for a not to exceed amount of $19,687.00.
There are funds appropriated in the 2011 Budget for these proposed expenditures.
Please include these items on the May 17 Village Board Meeting Agenda.
