AGENDA ITEM:
CONSIDER APPROVAL OF A RESOLUTION AUTHORIZING THE
PURCHASE OF A MANHOLENALVE CUTTER, EXTRACTOR
DISCUSSION:
Introduction
The purpose of this agenda item is to consider approval of a resolution
authorizing City staff to purchase one manhole/valve cutter/extractor from
Critex LLC. Of Lima, Ohio.
Historv
In June of 2008, the City Council approved a resolution adopting the 2009-
2013 Capital Improvement Program. As part of the Equipment Inventory
program for 2008, staff had included in the Future Additions, a manhole cutter/
extractor. Rather than jack-hammering the castings which is slow and labor
intensive, or utilizing the infrared unit to perform temporary repairs this unit
does exactly as the name implies.
Current Circumstances
Annually the City of Prior Lake adjusts/seals approximately 35 manhole
castings and several gate valves. The City also makes temporary repairs to
more than 50 manholes annually utilizing our infrared unit. Staff workload
during non-winter months prevent full repair of more than the 35 manholes
targeted annually. These castings are adjusted to prevent damage to City
snow removal equipment. The damage cause by a raised manhole casting
can exceed $3,000 per incident. Prior to the City beginning the adjustment
program at least one plow blade was damaged annually on these castings.
Additionally as part of the sanitary sewer inflow and infiltration reduction
program and street overlay program, staff has implemented an inspection and
improvement program for both sanitary and storm water chimney manhole
repair programs. This program seals these manholes as they are a primary
inflow location for storm water in to the sanitary sewer system.
Attachments A and B show two of the items which staff looks for during an
investigation of potential inflow and infiltration issues. Attachment A depicts
leakage and settlement of the bituminous street surface due to potential
deterioration of the concrete chimney rings. Attachment B shows the chimney
of attachment A with deterioration of the concrete rings and the infiltration of
water from the street sub-base. This type of infiltration can cost additional
money, both for pumping at lift stations and additional charges for treatment
from the Metropolitan Council Environmental Services (MCES).

Over the last three year period, staff has made permanent repairs or upgrades
to over 100 of 2,793 sanitary manholes and 35 storm water manholes. Staff
has also completed temporary repairs to more than 150 manholes over that
same time period. In 2009 staff will make 36 manhole repairs prior to the 2009
overlay project alone. The City also repairs and adjusts approximately 15 of
the more than 2,500 gate valve boxes annually. In 2007 staff investigated the
use of a manhole cutter/extractor to speed up and improve repair of chimney
manholes.
The cutter/extractor allows the City to increase daily completion of manhole
adjustments and seals from 9 to 12 with 50% less staff. The total staff time
savings are estimated to be $6,000 per year. This time can be re-allocated to
other street and storm water maintenance activities. In addition to the
reduction in staff time and costs, the appearance and durability of the repairs
is enhanced due to the clean removal of the structures. This piece of
equipment is not mechanical and is designed for long-term life of more than 20
years with only intermittent cutting tooth replacement. Over a 20-year life the
cutter will save the City an estimated $80,000 factoring in purchase and
anticipated maintenance costs.
Staff solicited quotes from the only two manufacturers that provide cutters that
meet City requirements. The first is a PECO unit provided by MacQueen
Equipment, the second is provided by Critex LLC. of Lima OH. The Critex unit
provides the ability to make the appropriate size cut in addition to a casting
removal attachment and reinstatement equipment, which would require less
labor and create time savings for the chimney repair process. See attachment
C and D. Attachment E provides a visual of the finished product once the
chimney and casting have been reinstated. Staff obtained quotes for the
manhole cutter/ extractor which are provided in the table below:

The quote provided by Critex LLC includes a $6,289 discount if the City orders
the cutter by December 21,2008. This provides the City with a $5,000 total
savings over the only other available cutter that meets City standards. For
that reason staff is requesting authorization to order the cutter prior to the end
of 2008 noting that payment will not be made until delivery 2009.
Conclusion
City staff recommends the purchase of the Critex manhole cutter/extractor to
speed up and improve the process thus reducing costs for manhole chimney
and gate valve repairs.
ISSUES:
This item is a specialty item and is not available on State Contract Pricing.
The reason staff brings this agenda before you at this time is to allow for cost
savings of $6,289 for the purchase of the manhole cutter/extractor. Critex LLC
R:\Council\2008 Agenda Reports\12 15 08\Manhole cutter agenda. DOC please attach color photos to agenda. DOC
provided a special discount price to the City of Prior Lake which is only good
until December 21st.
Staff discussed with Critex that the appropriate funds would not be available
for the payment of a manhole cutter/extractor until after the January 5, 2009
City Council Meeting. Critex has agreed that if an order for the cutter/extractor
is placed by the City prior to December 21st the payment can be made after
January 5, 2009.
The City has explored the opportunity of partnerships related to this purchase
with other communities. At this time neither Savage nor Shakopee plan to
purchase the equipment. Both cities have expressed interest in utilizing the
cutter in return for the use of their specialty equipment that Prior Lake would
otherwise need to rent. Prior Lake currently utilizes Savage's road grader and
brush cutter several times a year.
FINANCIAL
IMPACT:
Based on estimated staff time savings this cutter will allow the City to maximize
street department staff time.

manhole cutter/extractor is $31,827. Staff received two quotes for the
manhole cutter/extractor with Critex LLC providing the lowest cost alternative

II. Lease/RentaIOotions:
Lease and rental options are not available through vendors.
III. Zero Value Ooeration:

replaced as needed. Staff will utilize our current auger power head which attaches to
the skid loaders.
IV. Alternative Fuel Analvsis:
This certain piece of equipment will save on the amount of vehicles and trips utilized
by staff to get to accomplish the desired repairs. Because it is an attachment it does
not directly use fuel, however it is utilized by our skid loaders which do use bio-diesel.
V. Eauioment Utilization:
This piece of equipment can be utilized for both the cutting of manholes and gate
valve castings in the streets. These two processes require similar repair processes.
VI. Eauioment Partnershio:
The City has not found any interested partners at this time. However both Shakopee
and Savage have expressed an interest in utilizing the equipment in return for use of
their specialty equipment.
