INFORMATION_______________________________________________________________
Please replace “Alternate Bid No. 1 of 1” with the revised “Alternate Bid No. 1 of 1’ sheet
(attached).
Please revise section J 1.3.4 to include Layne Inliner (Note: all material will need to meet
specifications in accordance with JSP).
Please revise section J 1.3.5 to include LAYNE (Note: all contractors will need to meet
experience requirements per JSP).
Refer to the attached minutes and sign-in sheet from the pre-bid meeting for eligible bidders for
this project.
Refer to the attached parcel list of affected property owners.
Please revise the bid opening date and time to Wednesday, November 21, 2012 at 10:00 am
local time.
For all pipes, the pipe type, based on the Sewer Departments placement of a camera in the
manholes, appears to be Reinforced Plastic Mortar (RPM) or otherwise known as Truss Pipe.
Based on this, it doesn’t appear that a pre-liner will be required. However given the pipe
material, bids should be submitted based on a wet cure method as well as utilizing a “Neat
Resin” (per ASTM standards).

West Sanitary Sewer Line Rehabilitation Cured In Place Pipe
Meeting Notes/Minutes from the Nov. 6, 2012 Pre-Bid Meeting
Q.
A.
There was a question regarding the signature line on the bid form
See page P-7. It appears that the appropriate line is included on this page
Q.
A.
The water table may affect the required thickness of the liner
The water table is not known. Use the thickness specified in the bid documents for bidding purposes.
Q.
A.
Do we have any video of the line?
No
Q.
A.
Are there estimate flow?
Approx. 1.85 MGD average daily flow at lift station
Note: Please refer to JSP for bypass pumping requirements. Bypass pumping shall be of adequate sized and of capacity to handle
all flows, including peak daily flows, wet weather, and high-groundwater flows.
Pumping plans do not need to be submitted prior to bidding.
Avg. daily flow (dry weather) = 1.85 MGD
Avg. daily flow (wet weather= 4.3 MGD
Q.
Would the City only require a portion of the correction work at a manhole?
A.
If the City elects to have the manhole rehabilitated, the repair work should be for the complete repair per section L of the
JSP. This would include 1” think Cementitious liner as well as the epoxy liner. Other methods would be considered provided the end
product is equivalent to or greater than that described in section L. The City would have the final determination as to the
equivalency based on the Contractors submitted information.
Q.
What type of pipe will be encountered?
A.
The Sewer Department has located all manholes with the exception of MH # 18. This manhole may or may not exist. They
also place a camera in each manhole and it appears that all pipe material is Reinforce Plastic Mortar (RPM) also known as “Truss
Pipe”.
Q.
Can material removed during cleaning be taken to the treatment plant?
A.
Contractor will be responsible for collecting debris and proper disposal during the cleaning process. The material can be
taken to the City’s treatment plant.
Q.
A.
For bid alternate # 1, are all service lines the same size?
Please use attached revised Alternate Bid No. 1 sheet.
Q.
Does the Park Department have any major events planned?
A.
No major events planned this winter. For Dames park, flag football tryouts start in March and games are in April and May.
Regardless of planned events, contractor should take precautions to protect equipment, material, trenches, etc. and provide a safe
working area given the location of the work within a park. Depending on equipment and amount of disturbance, work could be
restricted during certain times around MH # 4.
Q.
Will the City require the Contractor to “jump around” and install the liner in several different size pipes
A.
The City will not require the Contractor to “jump around” and would anticipate the contractor to progress in a workmanlike
manner starting at one end (for example west lift station) and working to the other end (MH 20).
Q.
Is there a concern with noise?
A.
The contractor would need to adhere to the City Ordinances regarding noise. Having said that, if pumps or other
excessively loud equipment will be used in close proximity to residential homes and if they are used in a continuous manner and
after those working hours allowed by City Ordinance, special consideration should be given to minimize the impact to homeowners.
Q.
A.
Can the City provide a list of property owners?
List of property owners is provided as part of the addendum # 1.
Q.
A.
Will any question received be made available to all bidders?
Yes
Q.
Can the City provide funding levels for this 2012 and 2013?
A.
There is currently $634,000 available in 2012 and $750,000 requested in 2013 (pending Council’s approval of the budget at
the December Council Meeting.)
Q.
A.
Is pre-liner required?
If necessary, this should be included in the lf cost of CIPP.
Note: Based on the type of pipe, it doesn’t appear that pre-lining will be required however the type of pipe may require an alternate
curing method (wet cure) as well as an alternate resin (Neat Resin). See addendum # 1 for more information.
Additional questions receive to date:
Q.
Can subcontractors perform the preconstruction cleaning and preconstruction television inspection for this project?
(submitted by J and J Boring, Inc.)
A.
A subcontractor can provide these services provide they have adequate experience and can perform the work in
accordance with the JSP and other applicable standards.
Q.
A.
Can the pump station be drawn down during cleaning and televising? (submitted by J and J Boring, Inc.)
Yes. Contractor will need to coordinate with Sewer Dept.
Q.
Does the City of O’Fallon own the soccer field near the park to the South? Access Road to the field? (submitted by J and J
Boring, Inc.)
A.
The soccer/flag football fields and south loop road are owned by the City.
Q.
A.
Should the manhole # 18 be raised to grade? (submitted by J and J Boring, Inc.)
Sewer Dept. could not locate this manhole.
Q.
A.
Should manhole # 11 be raised to grade? (submitted by J and J Boring, Inc.)
No.
Q.
On the previous CIPP project Layne was listed as an approved contractor in the specifications – as Reynolds. Reynolds was
acquired by Layne in September 2005. In May 2012 all subsidiaries of Layne were asked to take on the Layne name so we now go by
Layne Inliner. Layne Inliner has installed over 15 million feet of CIPP. We are requesting that City of O’Fallon list us as LAYNE in the
1.3.5 section of project specs. (submitted by LAYNE)
A.
LAYNE will be an acceptable Contractor provided they meet experience requirements listed in the JSP’s.
Q.
In section 1.3.4 the specifications list the products allowed (liner) and currently shows the liner tube manufacturers that
Insituform and SAK might typically use. It does not include the one Layne Inliner uses (and has used). We are requesting that LINER
PRODUCTS be added to the list of approved CIPP products in the 1.3.4 section of project specs. (submitted by LAYNE)
A.
Layne Inliner will be considered an approved CIPP product provided it meets or exceeds the requirements listed in the JSP.

INFORMATION_______________________________________________________________
Disregard any Alternate Bid #1 related work and pricing from the proposal.
It should be assumed that all curing of any liner is to be done with hot water (wet cure) over
steam, as a worst-case scenario, until the final pipe material can be 100% verified by the
contractor during construction. All pricing should anticipate hot water curing. If segments of
pipe can be cured with steam based on the pre-construction inspection, then the Contractor may
submit a proposal to the City to identify the steam-cured sections. If there are any savings that
can be achieved by curing with steam, then those costs shall be credited back to the City.
It has been discovered that the minimum thicknesses for the linings of some pipe sizes are
conflicting throughout the bid documents. The correct thicknesses are found in the JSP’s. The
thickness for the 15” pipe remains per the bid form even though it is not mentioned in the JSP.
The bid form shall be modified as follows (please strikethrough the incorrect thickness and
write-in the correct thickness; no revised bid form will be issued):
• 24” Diameter CIPP (shall be 13.5 mm)
• 18” Diameter CIPP (shall be 10.5 mm)
