INTEROFFICE MEMORANDUM
TO: VILLAGE MANAGER, MICHAEL E. JANONIS
FROM: WATER/SEWER SUPERINTENDENT
DATE: MAY 7, 2012
SUBJ: BID RESULTS FOR SEWER REPAIRS USING CURED -IN- PLACE -PIPE
(CIPP) PROCESS ($661,431)
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 sanitary sewer repair work has been
slated.
This work primarily consists of rehabilitating existing sewer main pipes using a no -dig, cured -in-
place -pipe (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.
The CSSES ranked defects in a range of categories with Category 5 being pipes in the worst
condition and Category 1 pipes requiring little or no rehabilitation.
The rehabilitation work performed since 2005 resulted in the elimination of the worst defects
(100% of Category 5). Approximately 95% of the Category 4, 17% of the Category 3 and 5% of
Category 2 defects in our combined sewer system have been lined to date. A total of 67,028
lineal feet (over 12 miles) of sewer has been lined under this project
In addition, 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.
This memorandum presents the results of the bids for the CIPP work. Bid results for spot relays
will be presented in 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 16,690 lineal
feet of lining work in pipes ranging from 8" to 36" in diameter along with the televising and
cleaning of approximately 50,000 lineal feet of sewers

Bidder
Bid
Visu -Sewer of Illinois, LLC of Bridgeview, IL
$ 601,301.00
Insituform Technologies of Chesterfield, MO
$ 608,831.00
Hoerr Construction, Peoria, IL
$ 763,293.70
Kenny Construction, Northbrook, IL
$ 891,774.10
Discussion
Staff has evaluated all bids. All bidders submitted the required bid securities. Hoerr
Construction of Peoria, IL did not submit references or confirmation that they meet the bid
requirements for lineal footage installed for the lining system, lineal footage installed for the
contractor, or whether Hoerr Construction is an authorized licensee of an acceptable CIPP
system. Consequently, the bid submitted by Hoerr Construction is considered non - responsive.
All other bidders satisfied the bid qualifications and submitted responsive bids
Visu -Sewer of Illinois, LLC of, Bridgeview, IL is the apparent low bidder and provided all the
necessary material and references as outlined in the bid specification. Visu -Sewer has done
work for the Village in the past and their work has been satisfactory.
Staff is recommending that a 10% contingency ($60,130.00) be added to the contract to cover
any unforeseen expenses. 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
$661,431.00 ($601,301.00 base bid plus the contingency of $60,130.00).
