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

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

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).
