SUBJECT: Design for Pool Replastering
CAO RECOMMENDATION
1.) Award a contract to Rowley International for design and project supervision services for pool
replastering in the amount of$16,800
DISCUSSION
In the last quarter of 1997,the County of San Luis Obispo Health Agency notified the City they
were concerned enough with the deteriorating condition of the pool shell plaster to request
replaster work be performed as soon as possible. This concern prompted Public Works staff to
commission an independent report on conditions at the Swim Center to confirm the need and
options for this work(attachment 1). The resulting report from Rowley International concluded
the most prudent action would be to replaster within the next fiscal year(attachment 2). After
reading the report,the Health Agency has reaffirmed their position with a written
recommendation that the City complete replastering of the pool shell before the end of fiscal year
1998-99(attachment 3).
Public Works,along with the Parks and Recreation Department,has concluded that the best
window of opportunity for this project work,that creates the least inconvenience for patrons and
insures work is completed outside the normal rainy season,would be to begin immediately after
the end of the Labor Day weekend in September. Because of this window and the need to
replaster in the next fiscal year,Public Works must immediately complete design work to meet a
tight bid process timeline as shown below.

documents. Because of this we do not have time to seek RFP's for design services. Rowley
International is considered to be the leader in a very specialized field of Municipal Pool
construction. In addition, Rowley International has staff available and ready to perform this
needed work within the time flame required. For these reasons, it is recommended to award a
sole source contract with Rowley International for design services.
CONCURRENCES
The Parks and Recreation Director agrees that Rowley International is qualified for this work.
Furthermore, The Parks and Recreation Director and the County Health Agency are in agreement
that we need to perform this work in the fall of 1998.
FISCAL EMPACT
The proposal for design services from Rowley International is$16,800. Including a$1200
contingency,adequate fimding for the design phase is available within existing resources, so no
supplemental appropriation for this purpose is required. Appropriations for construction will be
submitted as part of the 1998-99 budget process.
ALTERNATIVES
The City could choose to wait until the fall of 1999 to approve this work. If this option is
chosen,there is a high probability the City could face pool closure at the discretion of the Health
Department should the conditions of or the conditions related to the plaster worsen. Closure of
the pool would impact revenue and have a substantially negative impact on the public and the
image of the City.

COUNCIL MEMORANDUM
December 9, 1997
TO: City Council
VIA: John Dunn,City Administrative Officer
FROM: Michael McCluskey,Public Works Director P4W--
SUBJECT: RELINING OF POOL NEEDED AT SWIM CENTER
Sinsheimer Pool opened for business in 1979. Although it is desirable to periodically perform preventative
maintenance on the dry plaster shell of commercial pools,the pool has never been drained to allow such action be
taken. This choice was agreed upon between Recreation and Public Works due to the unusually high year round use
of the facility,the cost of replacing then re-heating 750,000 gallons of water,and because diligent water quality
practices have kept the clarity of the pool at a consistently high quality level.
In 1988,some very limited delamination occurred and a consultant was hired to evaluate the condition. That report
identified that the shell was in good shape,even though a few small patches of plaster had let go. It was determined
that insufficient curing had probably occurred during construction due to wet weather conditions at the time. An
attempt to make an aesthetic repair of these areas underwater was made but proved unsuccessful. Even with the
unsuccessful attempt,the dela nination was so minor there was no need to drain the pool to make a successful dry
repair.
Starting in 1995,the health department began noting there was some new,but still limited,delamination occurring
in their regular inspection reports. In this situation,they routinely recommended replastering work be done;but did
not require it unless the condition got to the point that underwater ceramic tile also began to release from the shell.
Up until 1997,the condition was noted but not deemed severe enough to warrant closure of the pool. Due to the
slow deterioration of the pool plaster,both departments came to the conclusion that a closure of the pool would
eventually be necessary and it was decided to request funding for the repair in the 1999-2001 budget.
However,in 1997,a severe algae infestation occurred and was brought under control. As a result,the delamination
condition of the plaster shell accelerated dramatically. Currently there is almost uniform"pocking"of the plaster
over all areas of the pool bottom. Although no ceramic tile has come loose and the condition is still technically,
aesthetic in nature,the health department is strongly recommending we make plans now to reline the pool in 1998.
They are concerned the condition will continue to worsen to the point where it will become a heath issue and they
will be forced to require repairs be made immediately. Recreation agrees that a September through November
window is the least disruptive programming period for replastering work to occur. This work could take as little as
one month and as long as three. Given this tight time-same,bidding must occur in such a way that construction
work will be ready to begin the week after Labor Day. To be prudent,regular users are being notified now to begin
reserving alternative pool sites for their fall 1998 programming needs.
Staff is considering bringing in a consultant to independently evaluate the situation to determine if the County's
time-line preference is the only option. Assuming the consultant verifies the need to proceed,staff will be
requesting funding for this project in the 1998-1999 budget. It is anticipated there will be intense interest of users
impacted by the closing of the pool therefore,updated information will be provided as this situation develops.

SUBJECT: SINSHEIMER PARK POOL FACILITY EXAMINATION
Dear Mr. Davis=5u t-t H
It was a pleasure to meet with you and your staff to discuss the examination of the
Sinsheimer Park Swimming Pool Facility. On February 19, 1998, 1 visited the pool
site and met with Don Headley the Pool Operator and Deborah Smith-Cooke of the
San Luis Obispo County Health Agency. The following are our/RI comments and
recommendations regarding the facility:
PLASTER
The Pool Plaster surfaces have degraded over time and are rapidly beginning to
show the signs of chemical abuse. It is quite normal for a plaster surface in a well
maintained pool to last approximately 15 to 20 years. Towards the end of that time
span, the plaster will begin to break up and spall on the surface. This phenomenon
is due to the constantly changing chemical levels and resultant pH level shifts.
The breakdown of the plaster does not, in itself, present an immediate health care
concern; however, the resulting roughened surfaces can create additional concerns.
At the time of the inspection, the roughened surfaces appear to have allowed algae
to form and stick to the roughened surfaces. The SLO County Health Agency
believes that the presence of the algae can create additional concerns but at this
point, are satisfied with the City's heightened awareness and preventative measures
to minimize algae growth. Our/RI concerns also include the dangers of the
roughened surfaces and the potential for injuries to the feet of pool users. Don
Headley stated that if the roughened surfaces prove to cause feet and toe injuries,
the users could be provided with foot protection to eliminate the potential for injuries.

POOL SHELL
The Pool shell does not appear to show any signs of distress or failure. It is not
uncommon for pools of this vintage to begin to show some signs of rust or corrosion
from either the structural rebar in the floors or walls or from other metallic features of
the pool shell. This sort or corrosion may exist hidden beneath the existing plaster;
however, at this point it is not very likely and the shell should continue to provide
many years of service.
MECHANICAL SYSTEMS
The existing mechanical equipment package appears to be in a very good condition
and is operating within the required turnover rates. The existing circulation pump,
filter, and heating equipment, although state of the art at the time of the original
installation, provide adequate water quality at a reasonable operation cost. Current
trends in the Pool Industry; however, have led to more highly developed systems and
equipment that now provide a great increase in operational efficiency.
SOLAR HEATING
The existing solar system has been shut down due to numerous required repairs.
The repair costs can easily climb in value as the shutdown will likely cause addition
repairs. The solar panel technology in place at the time of installation is very much
behind the technology in use with modem panels.
CHEMICAL SYSTEMS
The existing chemical system utilizes bromine and ozone and appears to adequately
serve the facility. It should; however, be noted that this combination, although highly
regarded in some areas, has been blamed for skin irritations and other problems at
many facilities and has subsequently been replaced at many locations. The
underlying basis for these replacements comes from the fact that bromine is far more
expensive yet not as effective as chlorine for disinfecting and sanitizing a swimming
pool. The proper use of bromine requires many other costly steps to eliminate the
possibilities of the skin problems noted above.
The proper use of Bromine products should include maintaining an oxidation
reduction potential (ORP) of approximately 750 to adequately sanitize the pool. ORP
is the ability of the water to disinfect and sanitize the pool. In our discussion with the
Operator we were told that the goal is to maintain the pool at the 750 mark; however,
it had been in the lower 650 range on occasion. With the use of bromine all efforts
should be made to maintain the 750 level. If the ORP level stays consistently low,
health issues may arise in the form of increased bacteria counts and increased algae
growth.

RECOMMENDATIONS
The following are our/RI recommendations for the Sinsheimer Park Swimming Pool:
PLASTER
The existing plaster may continue to provide several months of continued service;
however, its is in need of constant attention to keep both algae growth and rough
surfaces to a minimum. We/RI highly recommend that the pool be replastered in
within the next year. We understand there are certain budget issues within the City
to take on such an unexpected project so it is certainly possible to stretch the'fife of
the plaster another budget year. The estimated cost of the plaster replacement is
approximately $100,000.00. If the City were to show a cash surplus the pool the
Staff and the users would all greatly benefit from taking on the project at an earlier
time.
POOL SHELL
There appears to be no problems with the existing pool shell. We/RI recommend
taking a much closer examination at the time of the plaster replacement. At that time
the Pool shell will be much more visible and any recommendations for repair can be
more easily determined. The absence of telltale corrosion stains leads us/RI to
believe that there are very few, if any, structural problems. Structural repairs would
likely not exceed the $10,000.00 mark and an estimate of $5,000.00 is more likely.
MECHANICAL EQUIPMENT
The existing mechanical equipment appears to be working in good general
condition. The only drawbacks appear to be in the lost efficiency of the older
equipment. Probably the best procedure, in lieu of total system replacement, would
be to systematically replace the existing systems one at a time as the system fails
with new high efficiency equipment. The existing equipment could be expected to
provide anywhere from three to seven years of additional service. The systems in
question are the circulation pump and the pool heater. The circulation pump is
probably operating at level approximately 15% below modem high efficiency pumps
and the heater is probably operating at level approximately 30% below modem high
efficiency heaters. These improvements would account for approximately
$22,000.00 saving per year and a payback of approximately eighteen months.
These systems can help to provide improved water quality at a reduced operational
cost.

Rowley Intemational Inc Mr. Davis- - 4 - April 10, 1998
SOLAR HEATING
It is very difficult to evaluate a failing solar panel system to determine the cost
effectiveness of repairing such a system. The best analogy can be made by
comparing it to a new installation. Probably the best example is the similarly sized
pool at Cal Poly San Luis Obispo. The State of California required a Solar
Feasibility Study prior to the completion of that project. As it turns out, the payback
time on the installation of a solar heating system was approximately 16 years.
Ironically the existing solar system at Sinsheimer is approximately the same age
(see Solar Energy Feasibility Study For Cal Poly Recreation Sports, Physical
Education & Event Center Swimming Pool enclosed).
Therefore at the time the solar system becomes cost effective, it begins to approach
the end of its useful life. Our recommendation would be to eliminate the solar
system, unless government subsidies for alternative energy return to improve the
cost efficiency. Installation of the new high efficiency Heaters described above
would help to offset the apparent increased operational costs that would result from
elimination of the solar system.
CHEMICAL SYSTEMS
Despite the current ozone problems, the existing chemical system appears to be
working fine. Don Headley's understanding and careful operation of the system is
partly responsible for the success that he achieves with the bromine system. Should
the city decide to extend the life of the plaster another year it will be taxing on the
existing bromine system and the staff to minimize the algae problems that will be
encountered. The current pool operators knowledge of the system will be
instrumental in the continued success of the bromine system. Any deviation from the
current operation status should be done with extreme care. Future consideration
might include a more effective chlorine system of sanitation if the bromine system
isn't able to be maintained at the highest level.
Please call me if you have any additional questions.

RE: Sinsheimer Pool Plaster Report Comments
Thank you for the opportunity to review and comment on the report from Rowley International
Incorporated. The report appears to be a fair representation of conditions at the pool at that time.
As you may be aware, Section 65535 (a) of Title 22 of the California Health and Safety Code
states that: "All parts of the pool and related pool facilities and equipment shall be maintained in
good repair. Floors shall be kept free from cracks and other defects...". The plaster on the pool
floor and walls continues to degrade, resulting in several rough surfaces that permit continued
problems with algae growth. This Department does not consider these conditions to be "good
repair." Although Rowley International Inc. states that the existing plaster may continue to
provide several months of continued service, it does state that the plaster is in need of constant
attention to keep the algae growth to a minimum.
Don Headley has succeeded in minimizing the algae growth through extensive cleaning efforts
and through maintaining acceptable chemical balances. However, Don has retired and it is
expected that the level of experience and consistent attention to the pool that Don provided will
likely change.
To facilitate ease of pool maintenance in Don's absence, and in light of the above-mentioned
information, this Department strongly agrees with Rowley Internationl Inc.'s recommendation
that the pool be resurfaced within the next year(by April 1999). We therefore believe it is in the
best interest of the City to proceed with the resurfacing of Sinsheimer Pool between now and
April 1999.

PURCHASING CONTROL PROCEDURES 2014
subject: Elements and Waivers of
Competitive Purchasing
Waivers of Competitive Purchasing
Although competition is required whenever practical, exceptions are permitted
when competitive purchasing may not be feasible for specific commmodities,
services and circumstances. EWicyees assigned purchasing authority must use
professional judgment and skill in determining when a waiver of competition is
appropriate, ensuring that the waiver is consistent with prescribed policies
and- procedures, and documenting the exception in accordance with the
instructions contained in Part 4. The conditions and circumstances for
waiving competition are reasonably constant, and are defined below:
1. Emergency Purchases - Emergencies of one kind or another are the most
common situations for which requirements for competition can be waived.
The officials who determine that an emergency exists are limited to those
in positions of high responsibility. In all cases where purchases are
made outside of normal procedures, records must be maintained to indicate
the types and quantities of items purchased, the vendors from whom they
were purchased, and the disposition of the items. Where possible,
informal quotations should be obtained and recorded. If it is not
possible to obtain quotations, that fact must be recorded, even on an
after-the-fact basis if necessary. The complete record of emergency
purchases must be submitted to the Finance Department for a procedural
post audit within forty-eight hours of the end .of the emergency
situation. (Refer to Section PC-404-2 for detailed procedures)
2. Single-Source Purchases - A single-source supplier is the only acceptable
vendor who is able to furnish a certain item or service. Single-source
purchases are infrequent exceptions to competition, and care must be
taken to avoid them because of their bias or preference for a particular
product made by a particular company. In making a single-source
determination, the responsible official must consider the following
factors:
- Is there a lack of responsible ccmpetiticn for a cc modity or service
which is vital to the operation and best interest of the city?
- Does the vendor possess exclusive and/or predominant capabilities?
- Is the product or service unique and easily established as
one-of-a-kind?
. - Can department or program requirements be modified so that competitive
ATTACHMENT 5

Competitive Purchasing
products or services may be used?
- Are there patented or proprietary rights that fully demonstrate a
superior patented feature not obtainable from similar products, or a
product available from only one source rather than dealers and
retailers from which competition could be encouraged?
When a single-source purchase is justified and irpevitable, the reasons and
action taken must be supported by written documentation. The written
justification must be approved by the Department Head and.suhmitted, with the
reg s;ticn or proposed contract, in lieu of a written tabulation/evaluation
of bids or quotations.
