Proposal for Inspection of the 250,000 Gallon Elevated Water Tower Located
in the City of Columbia Heights, MN.
M Project # MN2496
Dear Mr. Hansen:
KIM is pleased to submit this proposal to inspect the 250,000 gallon water tower prior to
October V, 2014 in Columbia Heights, Minnesota. KIM proposes to perform a detailed
inspection of the existing conditions of this water tower in conformance with AWWA Manual
M42 Appendix C Inspecting and Repairing Steel Water Tanks and Elevated Tanks for Water
Storage. This type of inspection is not just a verbal report on existing conditions. The report
submitted after the inspection will break down in detail the interior and exterior coating and
structural conditions. Color photographs substantiate the details of this report. The KIM report
will also indicate any unsafe OSHA conditions observed. The report closes with an Engineer's
Cost Estimate of the recommended structural and coating repairs or replacements, which is
essential for adequate budgeting.
By choosing KIM Engineering, Inc. the City of Columbia Heights is investing in the knowledge
and expertise of a consultant who is considered the foremost expert in the Midwest and can
perform an accurate and unbiased inspection of your water tank. In addition, KIM Engineering
did the last inspection of this water tower and is familiar with the tower and city personnel. Our
inspection will clearly identify all of the maintenance requirements of the tower.
The experience of KLM's staff in water tower inspections has been enhanced by our training as
National Association of Corrosion Engineers (NACE) Certified Coatings Inspectors and
American Welding Society (AWS) Certified Welding Inspectors.
City of Columbia Heights, MN
KIM will provide to the Owner two (2) copies of the inspection report, which will provide the
following benefits:
1. Clearly stating the actual condition of the coatings and structural integrity.
2. Identify the amount of sediment and estimate the next time it needs cleaning.
3. Provide a schedule for performing recommended maintenance work.
4. Provide an Engineer's Cost Estimate for all recommended repair work.
5. Color photographs and DVD substantiate details of the report.
6. Copies of the report justify maintenance recommendations to decision - makers.
7. The inspection report can be included in the specification document to provide accurate
information on existing conditions for bidders.
8. Recommendation of future inspections.
9. KLM will also provide drawings in the report for future maintenance.
Floatdown Inspection
The floatdown inspection is KLM's most frequently used and most comprehensive inspection.
This method of inspection provides the inspector /engineer with more information than the other
types of inspection.
KLM will provide NACE Certified Coating Inspectors, with one or both of these individuals
being an AWS welding inspector, whom are properly trained and qualified to perform this type
of inspection. If the tank can be drained in a single day (8 hours), this will enable it to be
inspected, cleaned, and disinfected in a one -day inspection.
In order to perform a complete floatdown inspection, the Owner must have the water at or near
the high water level (HWL) at the start of the inspection. KLM inspectors will insert and inflate
a sterilized rubber raft into the tank interior. During the float inspection, the Owner will be
responsible for opening and closing the valves to the tank. The inspectors will notify the
Owner's personnel when to start draining the tank and at what rate. The inspector, while in the
raft, will examine the interior structure and evaluate the existing coating integrity. KLM will
inspect the roof, roof structure, all appurtenances such as vents, manways, and ladders, the tank
shell, and the bowl. KIM will be responsible to provide a safety ladder and a lifeline in the roof
manway, for the interior inspector, at all times. The inlet pipe or wet riser is excluded from the
inspection, unless otherwise written into this agreement.
The clean-out and disinfection will be performed in accordance to the proposal. Clean-out can
be performed using a 3000 -psi pressure washer if necessary. KLM will pull the pressure washing
hose and gun up through the wet riser and rinse out any sediment from the bowl. KIM will
supply a sump pump and pressure relief valve for the Owner if needed for the clean-out of the
wet riser. KIM will disinfect the tank in accordance with Method 1, 2, or 3 of AWWA C652 -11.
KIM will require the assistance of the Owner to back -flush and disinfect the reservoir of the
tank. KLM can supply the chlorine and do the clean-out from the bottom.
City of Columbia Heights, MN
KIM Engineering, Inc. can also perform the following type of inspection,
ROV Inspection
KIM plans to utilize a two -man crew and a Remote Operated Vehicle (ROV) to perform the
inspection. This inspection method can be performed in one day. The ROV inspection is used
primarily when performing warranty and 5 year anniversary inspections.
KIM will provide NACE Certified Coatings Inspectors, with one or both of these individuals
being an AWS welding inspector, whom are properly trained and qualified to perform this type
of inspection. In order to perform an ROV inspection, the city would be required to have the
water at or near the high water level (HWL) at the start of the inspection. KIM inspectors will
insert a disinfected ROV into the tank interior, for the interior inspection of the roof, roof
structure, and all appurtenances such as vents, manways, and ladders. Videotaping will be
performed with an underwater camera, which will show the coating deficiencies. The camera
will be disinfected in accordance with AWWA. KIM will be responsible to provide a safety
ladder and a lifeline in the roof manway, for the interior inspector, at all times. The inlet pipe or
wet riser is excluded from the inspection, unless otherwise written into this agreement.

KIM will inspect the floor, the reservoir walls, and any interior structure accessible by ladders.
All accessible exterior surfaces, including the roof, will also be inspected. KIM will measure
and photograph all areas that need to be included in the inspection report. KIM will provide a
ladder.
All inspection will be completed in accordance to AWWA MANUAL OF WATER SUPPLY
PRACTICES M42 Steel Water Storage Tanks.

The exterior inspection is critical for evaluating the coating conditions to determine whether the
coating is a candidate for over coating or complete reconditioning. KIM 'inspectors will also
check for structural deficiencies and OSHA compliance.
For each inspection, KLM will provide a MACE Certified Coatings Inspector that is properly
trained and qualified to perform this type of inspection. The exterior will be inspected from all
areas accessible without rigging unless otherwise written into this agreement. Coating conditions
of both the interior and exterior will be examined using a number of different testing equipment.
KLM's inspection will include using ultrasonic thickness readings UT, dry film thickness DFT,
and standard ASTM tests.

Option 1: Floatdown Inspection
The inspection will be performed for a fee of $3,800.00.
Option 2: Remote Operated Vehicle (ROV) Inspection
The inspection will be performed for a fee of $2,800.00.
Option 3: Dry Tank Inspection
The inspection will be performed for a fee of $2,500.00.
Following the inspection the report should be out in three weeks.
If for some reason beyond KLM's control, the inspection of the tank cannot be performed in one
day (8 hours). Tanks that have excess sediment and require more than one hour of cleaning time
may result in extra charges above and beyond the original contract amount. If KIM were
requested to take coating samples from the tanks to check for lead and chromium this would be
an additional $500.00. Fees are subject to change if proposed work exceeds 12 months from this
bid proposal.
