Dear Mr. Olsen:
Subject: CITY OF RENTON STANDARD CONSULTANT AGREEMENT -
' ADDITIQNAL INSURANCE REOUIREMENTS
CH2M HILL is in receipt of the additional insurance requirements the CITY OF
RENTON has submitted for our review and consideration. CH2M HILL has reviewed the
additional insurance requirements and provides the following fa-Aback:
• The CITY OF RENTON requests that the Commercial Generl Liability policy be
in an ISO 1993 Occurrence Form or Equivalent. CH2M HILL's Commercial
• General Liability policy form is an equivalent to an ISO 1988 Form.
The City requests that CH2M HILL's Commercial General Liability coverage
include Contractual liability (including Amendatory Endorsement CG 0043 which
includes defense coverage assumed under contract). This endorsement has not
been approved by the insurance regulators in all states. CH2M HILL's policy
underwriter is in the State of California. The Amendatory Endorsement CG 0043
has not been approved in the State of California,and,therefore, is not pan of
CH2M HILL's insurance coverage.
r
• The City requests that CH2M HILL carry a$5,000 limit of liability for Medical
Payments(any one person). This coverage is not included under CH2M HILL's
Commercial General Liability.

Tom: 1 was just paging through my project notebook and noticed that one of my field reports indicated the
possible presence of oil on the interior surface of the standpipe. Apparently the al Spots tame from a
ing in the standpipe. 1 had told Production to make
malfunctioning spider that Production Finishing was us
sure they pick up those spots. We should have Long Painting look for those spots and solvent clean,as
appropriate,to remove the oil spots.
Let me know If you have any questions. I will try to call you this afternoon.

review and approval.
I spoke with the President of Polybrid(George Ramirez)on Monday,and he mdica:- I the following:
1, The minimum recommended coating thickness for this tank Is 25 mils(as oppo—A to 20).
2. Surface profile should be a minimum of 3.5 mils attar sandblasting.
i 3. Aker Long Painting has had a chance to review the tank interior,they should cl aiss how to treat the
joint laps(gaps)on the tank interior ceiling with Polybrid. The Polybrid coatlnc, designed to be a
continuous-we should avoid any b'sake in the coaling• it may be possible to'.-'dge the gap where

1ECHNICAI. MEMORANDUM CWHIU
Tank Corrosion
PREPARED FOR: Lys Hornsby,City of Renton
Tom Malphrus,City of Renton
PREPARED BY: Karen Komher,P.E.,Structural Engineer
COPIES: Jerry Dupportg/SEA
DATE: SeFtember20,1996
1 visited the site of the Rrmton Highlands tank on August 27 with Jerry Duppong.At that
time,the painter had vndblasted about half of the upper portion of the tank I was asked to
look at the reported corrosion from a structural standpoint
l noted there was heavy corrosion in vertical streaks. 1 was immediately concerned because
the tank was probably designed to hold the water in hoop tension.While tension stresses can
1 typically bridge around pin-hole corrosion,the streaks were too long to bridge,so the
available material to carry the hoop tension was whatever was left beneath the corrosion.
Jerry measured pit depth and found a maximum depth of approximately 0.1 inch. The
painter indicated that he had seen deeper pits;we assumed that pits up to 1/9-inch deep had
occurred in the 1/4-inch plate.The portion of the tank that I looked at was not this badly j
corroded.
Tanks like the Highlands tank are very specialized structures,and tyically only a few firms
nationally can perform the calculations required to determine the extent of the problem. I
talked to both Bob W osniak,who is an independent expert in this field,and to Steve Meyer at
CBI,who both confirmed my suspicions about the potential severity of the problem.They felt
that only the upper portion of the tank was probably critical,smce the worst corrosion
appeared to be there,and because a recent code change increased the allowable stresses in the
lower portion of the tank
i
In order to make an accurate assessment and provide recommendations,it will be necessary i
to do a thorough investigation of the extent of the corrosion.This will require special rigging
and equipment to access th,tank wells. CBI is probably most suited to do this work since
they originally designed and constructed the tank. Other firms,such as PDM or Mr.
W osniak,using a painting subcontractor to provide access,also have the capability to do this
work,but it is important for the firm doing the analysis to do their own investigation,as they
are interdependent. <
My understanding of the potential outcomes of the inwstigaeon are:
• The tank could be safely operated at a lower maximum water elevation.
• 11 there are just a few places where the corrosion is deeper than typical,these could be
welded,and the safe operating level would increase from that detemvned above.
• The plates could be replaced. '
We strongly recommend that this investigation be done by a firm specializing in this work to
allow you to make the best possible decision repardint.the rehabilitation of this tank.

Message:
Per my telephone message earlier this afternoon:
1. Attached are two test results of the tightly-adhered black deposit In pits on the tank wall. These tests
indicate that the material is primarily iron oxide. One sample shows only iron and oxygen. The
second sample shows iron and oxygen with a trace amount of calcium and silicon. Calcium and
silicon are common constituents in potable water and could be included in the deposit through,he
electrochemical corrosion process. I am sanding a copy of this information.o Ron at Production
Finishes
2. We spoke with C81 about me effect of corrosion pitting on the strength of the tank. They responded
with the attached letter. I would like to moot with you and Lys as soon as we can to discuss the
options and direction we want to go.
Please give me a call when you have had a chance to review the attached.

Tom'.
Ray Sled called me yesterday to discuss some concerns he has about the Highlands Tank painting. Ray 'I
Is primarily concerned with having the tank out of service for 2 months while the interior is painted Me i
mention.a %at he had heard of a flame-spray coating that could be applied and would cure instantly I am
aware of I: ,coating procedure•but have not seen it used on potable water Larks. I checked with the
Plastic Flame Spray.and they have a product that is NSF listed as an acceptable material for potable I
water. I have some hesitation recommending this product since I do not know of a local applicator who
can apply this material. Nor do I know of a local representative. They may be around.but there may one iI be one or two applicators,if any,in the Puget Sound area.
There is another coat g that is available that does have the NSF listing for potable water. This is a 1100%
j solids urethane coati (manufactured b Madisson Chemicals,Ontario,Canada)that can be applied
one coat to a thickness of up to 40 mils. It cures in one hour. Obviously,this is a real advantage and
could reduce the coating schedule by at least two weeks(the estimated time of cure for the specified I
epoxy coaling). We have not used this product on water tanks in the Puget Sound area, but Seattle
Water apartment has. I spoke with Martin Jacobsen about SWD experience,and it seems to be
genera good. SWD's major concern related to surface preparation associated with repair of damaged
coatings(since the coating cures very rapidly,any repair coating will not chemically bond to the first coat:
the first coat must be sufficiently abraded before repair coatings are applied). I do not have a good handle
on the cost difference associated with this product over what we presently have in the specifications,but I
can do a little more work on this next week if you wish. y
Here are some of the Issues that will need to be considered for this product. C -
1. The 100%solids urethane can be applied in one c at to the required Ihlckness. The coating thickness
can be Increased In areas of the tank where poling has occurred.possibly eliminating the need for the
epoxy mastic filler (I")
2. The product cures instantl!allowing the contractor to proceed directly with disinfecting the tank, and
eliminating a 2 to 3 week cure period for an epoxy coating.
3. The product is NSF approved for potable water.
4. The product will cost more per gallon and it must be applied with specialized equipment,resulting in a
higher project cost
5 The product is tacky to apply. It must be applied by an experienced applicator certified by the coating
manufacturer. I have identified one certified applicator in the Puget Sound area-the coating
manufacturer indicated they could certify other contractors before the bids were due(it would take less
than two weeks).
i 6. 1 spoke with a local coating contractor regarding schedule. He felt that the coating may De applied in

to 4 weeks,possibly less than three weeks if the contractor could put on two shifts(ham to 9pm)
7. If we change the specs we wilt need to make some modifications to cover quality control issues
(contractor certification and manufacturer's services)and coating repairs associated with this product.
;s well as the product definitions and application thickness.
8. 1 do not know what affect changing the coatin material will have on the review that was done by DOH.
We should be able to find out with a quick phone call-I would be hopeful that there would be no
further review requirement since we are still using an NSF approved material and are not changing
anything related to the disinfecting procedure.
9. Other special issues that may develop as a result in discussions with the coaling manfucturer.
I will be out of the office today and Friday. Would you have time to discuss these issues with Ray and Lys

Message: j Tom: I checked sandblasting production rates for the Highlands tank. Roughly calculating the surface
area the contractor sandblasted in the tank bowl,and assuming it took 8 hours to accomplish this much
surface preparation, I estimate that the production rate is about 80 square feet per manhour This
correlates with information in one of my paint manuals. Therefore,it will take about 122 hours(130.8)to
finish sandblasting the interior of the tank bowl. For two sand blasters,figure about 67 hours and for
three sand blasters estimate 47 hours. If the contractor works 10 hour days(assuming this is the most
sand blasting he win accomplish with breaks and equipment problems),then it might take him another 5
hree
ters
that woul be next
ddays to nish the surface pr oesn't(work the weekend)f eWeashould knpartion with tow more so o(rrow after they start on theawalhs nd ceiling.

MEMORANDUM CWIHILL d
Highlands Tank Painting
nn Tom Malphms,City of Renton
MOM: Jerry Juppon$CH2M HILL
oarE: September 23,1996
Tom: Pursuant to cur conversation last Friday,this note summarizes some of the"punch
list"items that the painting contractor will need to address at Highlands. k
i The last time I climbed the Highlands water tank(August 29th),I noted several items that
will need to be corrected by the Contractor before the project is completed.
I 1. One of the anodes is broken(anode stung next to the access ladder). This anode or
anode string will need to be replaced.
2. The Contractor had a small compressor on the top of the tank. It leaked oil. This oil
will need to be removed.
3. The Contractor was usutg a spider to pro%nde access to the railing. I noted several spots
of oil on the bnttom of the tank bowl where the spider was"parked". It appeared to me
- that the spider motor was leaking oil,and that when the Contractor began to lower the
spider,the motor sprayed oil onto the bottom portion of the tank bowl. This will also
need to be cleaned.

Tom. Karen Kornher(our structural engineer)and I met with Ron Stipec and Bill Vangerpan(steel
fabricator)this horning It looks tome like the Contractor is on the right track. °t
4
After our meeting, Karen had a few comments that she wanted to pass on to the Contractor. Since these
comments might be helpful to the Contractor before he makes his field measurements on Monday,I
forwarded a copy directly to Ron this afternoon.
I need to talk to you briefly about how you would like communications to flow for this project. My
preference would be to have all major communication with the Contractor go through you so you can
keep abreast of events as they unfold. Let's talk some about this on Monday.
t .:a
I hope you don't mind that I sent this memo to Ron-but it looked like the information would help him with
his measurements and,hopefully,will help us through the structural submittal in a more timely manner. a
Also, Karen indicated that she saw no reason why the Contractor could not go ahead and order materials. '
However,I asked that the Contractor wait until Monday so you and I could talk before they order. Karen .1
felt that they could go ahead and order the materials,but the submittals should be in hand before they
begin fabricating.

Tom: I reviewed the time that I have spent on the Highlands project since the Contractor left the site.
Much of my time during this period was spent on the structural concerns and negotiating with Chicago
Bridge and Iron. I estimate that approximately 15 hours have been spent on activities related to the
Contractor's default(site meeting with bonding company and contractors.telephone discussions with the
City and bonding company.cost estimates,revised specifications,etc.).
The cost of engineering services that will be required to complete the project depends on when the coating
work is completed. Coating activities in the winter months will require closer observation in the colder
environmental conditions. We estimate that an additional 24 to 32 hours may be required to complete this
work.

If the contract is to be re-issued.additional engineering costs (squired to include existing conditions

incorporate existing conditions Is 24 to 32 hours.

Dear Ron:
The F6gnlands elevated water storage tank has been out of service since July,1996 for e-
repainting of the tank interior. The original low-bidder for the painting project defaulted
on the contract when the company went out of business,and the tank has remained out of
service while the City has negotiated with the bonding company to complete this project.
It Is in the best interest of the City to return this tank to service as quickly as possible. The
City currently has a bid from long Painting Company to complete this work. Long
Painting is a large,regional painting contractor with the st,df and equipment required to
complete this work. The protective coating for the interior of this tank requires special
certification from the paint manufacturer. It is our understanding that Long Painting has
undertaken the special training required by the paint manufacturer for application of their
product. Long Painting also has the special equipment required to apply the coating.
In our opinion,Long Painting Company is well suited to provide a quick response to
complete this tank painting project and finish the project in a most timely manner.

To: Tom Malphurs From: Jerry Ouppong
Company: City of Renton Date: October 17.1996
Message:
Tom. Per our conversation this morning,1 see no technical reason why we cannot switch to a polable-
grade epoxy paint for the Highlands tank. This is the product we initially specified,but changed to the
polyurethane coating for its fast cure properties. It seems to me that healing the polyurethane type coating
will present some problems,especially since the application period will move into the cooler tall months.
Madison Chemical does not list the temperature required for application of their product in the product data
sheets,but a competitor's data sheet indicates that material must be preheated to 75 to 90 degrees F and
applied at 130 to 140 degree F at the gun. I believe that it will be difficult to maintain temperature of the
product Irom the mixing/storage containers through the hoses to the application gun. It could be done,but
it is another factor that must be closely monitored to make sure the product is applied properly.
The downside to the epoxy coatings is cure time. Several manufacturer's can provide"fast cure"or"low
temperature-curs"epoxy coatings that can be applied at 35 degree F. At 35 degrees F,it will take
approximately 3 weeks to cure. The cure time might be reduced it the dehumidifier is left on and the tank
is well ventilated.
The vast majority of steel tanks in the Puget Sound area have polyamide epoxy coatings on the inside,so
many contractor's have experience with this product. There are also several local technical
representatives for epoxy products. I consider these positive aspects for this coating.
For your information,I attached sections of the original draft specifications that show the epoxy paint. I
modified the product description to provide a low-temperature cure paint and for the coating thickness to
end up at tff mils(this should help Coat pitied areas and other possible areas difficult to Coat•such as
rough welds).
Give me a call it you have any questions.
P.S. I found a few other items of correspondence with PFI in my files that I am sending you this afternoon.
I think you have copies of this already,but I will send just in case.
