Cape Coral VA Outpatient Clinic
PROJECT IMPACT
The new Cape Coral VA
Outpatient Clinic has been an
important stimulus to the
southwest Florida economy.
At the time of the January
2010 groundbreaking, Fred
Pezeshkan, president and
CEO of Kraft Construction
Company, Inc., said about
600 subcontractors and vendors for the construction job
will be hired from Lee,
Charlotte, and Collier counties. A few months later, Bob
Koenig, senior vice president
and area manager for Kraft
Construction, told the Cape
Coral Construction Industry
Association that 80% of the
suppliers and sub-contractors for the project were procured in
Lee, Collier, and Charlotte counties.
B & I CONTRACTORS
W
hen the new Cape Coral Veterans Administration
(VA) Outpatient Clinic opens in spring 2012, military
personnel and retirees on the Gulf Coast will be able
to utilize a conveniently located, state-of-the-art facility for
medical care and other services. As a key player on the construction team, B & I Contractors, Inc. in Fort Myers can take
credit for the projectʼs complex plumbing and mechanical
aspects.
“Everyone from our plumbers, pipefitters, and tin-knockers
worked hand in hand with the general contractor and other
subs to make this project a success,” said Vincent Cicchesi,
supervisor/estimator, plumbing service & special projects,
B & I Contractors, in an interview with
. Manhattan Construction (Florida), Inc., formerly
Manhattan Kraft Construction in Naples, was the general contractor for the $53 million project.
Established in 1960, B & I Contractors specializes in commercial, institutional, and industrial construction with services
that include HVAC, plumbing, pipefitting, sheet metal, electrical, and fire protection service. “This was a very significant
project for the Gulf Coast,” said project manager Ashley
Fernandez, B.S.M.E. “There were also a number of interest
features about the job that point to where the Florida plumbing market is heading.”

January-February 2012
The new clinic is designed to replace an older veteranʼs
clinic in Fort Myers that opened in 1979 and no longer has the
capacity to meet the growing population of retired U.S. military personnel. Although there are an estimated 200,000 veterans in the region—including 68,000 in Lee County—the
older clinic offers only a limited number of services. As a
result, veterans who require advanced procedures have had
to travel to St. Petersburg for treatment at the Bay Pines VA
Healthcare System.
In a 2010 article in the
, Ralph Santillo,
founder of the Invest in Americaʼs Veterans Foundation in
Cape Coral, said the new clinic may encourage more veterans to relocate to the Fort Myers area, knowing about the
convenient services. That benefit, plus a great deal of affordable housing in the region, may help economic recovery
process for Fort Myers and Cape Coral.
“We are talking to vets outside the area to relocate down
here because we have the facility coming up, and we have a
reasonable housing market right now,” he said. Currently,
about 25% of the people living in southwest Florida are veterans, according to Santillo.

and equipment.
PROJECT SCOPE
The Cape Coral VA Outpatient Clinic is 224,000 square
feet, three times the size of the older Fort Myers VA Clinic.
The facility will occupy a 30-acre site, stand 89 feet tall, and
include 900 parking spots. The building itself is split into two
quadrants: a two-story section and a four-story section. Two
thousand tons of steel and 26,000 cubic yards of concrete
were being used for the clinic, according to a Kraft Construction article.
The facility will be a comprehensive, multi-disciplinary specialty care and outpatient clinic offering services such as primary care, mental health care, diagnostic radiology, laboratory services, audiology, cardiology with cardiac non-invasive
diagnostic services, urology, GI, orthopedics, ophthalmology,
dermatology, minor surgery, and advanced imaging including
CT, MRI, fluoroscopy, ultrasound, nuclear medicine, mammography, and vascular Doppler ultrasound. It will include a
Women Veterans Healthcare center, serving female veterans
on the Gulf Coast.
Faith Belcher, spokesperson for the Bay Pines VA Healthcare System in St. Petersburg, the administrator for local veteran care, said in a 2010 article that the design of the facility
allows for a tower to be constructed with beds and other inpatient services when the need arises. It may also be able to

the future.
B & I Construction was responsible for the mechanical
and plumbing scopes, said
Fernandez. “The building includes operating rooms (ORs)
with their respective recovery
rooms, dental surgery rooms,
and many office spaces,” he
said, noting there were about
100 bathrooms to be installed.
“Months of detailed and extensive overhead coordination
between the many trades were
a critical part of this project.”
PLUMBING
Cicchesi noted that the plumbing scope includes sanitary,
domestic water, condensate, medical gas piping, natural gas,
and fuel piping. “For the domestic water system we furnished
and installed a 30,000-gallon steel underground tank, a fully
redundant booster pump package in a fiberglass exterior doghouse, and all interior equipment and plumbing fixtures,” he
said.
Another challenging aspect of the project was plumbing for
the operating rooms, which have a full welded stainless steel
ductwork system with all stainless accessories, as well as a
decontamination room for sanitizing surgical scalpels and
other instruments.
Cicchesi said the B & I team had to install oversized sensor-operated hand-wash sinks for use by the clinic staff prior
to entering the OR areas. “These were wall-mounted units,
approximately 4.5 feet wide and 3 feet tall, with their own mixing valves,” he added.
There were also four water softeners—handling more than
300 gallons—with a 6-inch flow, added Cicchesi. “We handled
all the stainless steel welding, piping, and ductwork, while
subbing out the low-voltage electrical work.”

MECHANICAL
For B & I Contractors, the mechanical scope included three
350-ton water-cooled chillers, a 35-ton air-cooled chiller, a
70-ton heat recovery chiller, along with 17 air-handling units
and 34 fan-coil units.
The mechanical system included ERVs on all air-handling
units to recover the energy from the exhaust air. The main
makeup water supply to three cooling towers is the condensate from the air conditioning units, which are capable of providing 533 gallons per hour of condensate water at peak
load. “This facility is 100% drained,” said Cicchesi. “All condensate lines run to one area and recirculate to the cooling
tower.”
The heating hot water system is fed by three 2500-MBH
boilers, which provide heat to more than 350 variable air volume units with heating coils to control room temperature. B & I
also handled the natural gas connections to the boilers and

fiberglass fuel tanks, three generator day tanks, and a fuel oil
maintenance system.“The unique mechanical aspect of this project included a
fully louvered generator room, which was made up of large,
stackable hurricane-rated louvers,” said Fernandez. “The
generator room is located on the second floor level, making
this a very complex installation.”
MEDICAL GASES
The VA Outpatient Clinicʼs medical gas system included all
medical gas equipment, alarm panels, and the installation of
35-owner-supplied head wall units. “One of the biggest challenges on the plumbing scope was the large amount of
owner-supplied equipment requiring plumbing connections,”
Fernandez said. “Close coordination was required with the
owner and general contractor in order to correctly complete
the required rough-in.”

Key water heating charts
and formulas
It’s 2012 already, and in this
issue we will try to give you plenty
of information and useful charts
related to water heating. I donʼt receive many requests, so I am glad to accommodate
one on such a pertinent subject. The best part is that you wonʼt have to read too much
from me as these charts and formulas speak for themselves! So here we go …
BTU
GAS INFORMATION
A British thermal unit (Btu) is a measurement of heat energy. One Btu is the amount of heat energy required to raise
one pound of water by 1ºF. Water weighs 8.33 pounds per
gallon, so we can calculate that one gallon of water requires
8.33 Btu to raise the temperature 1ºF.

SUMMARY
There is a lot of other information that we could add, such
as steam. It is a viable heating source and there are several
factors that must be considered, such as operating pressure,
steam trap, condensate line sizing, and so on. We will have
to do a separate article on steam in a future issue.
The charts and information above are all essential to water
heating. They are proven mathematical formulas of algebra
and geometry. If you input the accurate information, then the
results will be correct. It is also good to use the online tools
and calculators. They are true time savers.

Keeping a plumbing
system free of Part III
in a
microorganisms series
by Abigail F. Cantor, P.E., Chemical Engineer
This is the third article in a series about the possibility of
microorganisms growing in plumbing systems. The first article
warned that with high residence time, high surface area, and
no disinfection, microorganisms can grow out of control in
plumbing systems. The second article provided a tour of a
plumbing system, pointing out where and why microorganisms are likely to grow.
This article describes three actions that can prevent
microorganisms from growing out of control in a plumbing
system:
1. Flushing
2. Disinfecting
3. Monitoring
FLUSHING PIPES
Unfortunately, while flushing of pipes with fresh water will
keep the population of microorganisms down, it is not always
practical for plumbing systems in buildings. Flushing requires
a large quantity of water, especially for buildings with a long,
complicated piping system and a large volume of hot water
storage.
In addition, a high velocity of water is required to remove
biofilms from pipe walls once they are attached. It may be
impossible to reach these cleansing velocities if pipe diameter and tank volumes in the plumbing system are large or the
water pressure is too low. A high velocity, also, cannot be
maintained in the multiple bends and branches of a buildingʼs
plumbing system. Even if a scouring velocity can be
achieved, some biofilms continue to adhere firmly to pipe
walls.
Table 1 shows the flow rate of water required to achieve a
flushing and scouring velocity of six feet per second.

DISINFECTING WATER
An alternative to flushing with a large volume or a high
velocity of water is flushing with a low volume of disinfected
water. There are a number of types of disinfecting chemicals
that can be used, but a common chemical for drinking water
is sodium hypochlorite which provides chlorine as the active
disinfecting ingredient. Another name for sodium hypochlorite
is bleach, which can be purchased at grocery and hardware
stores. It is important to purchase household bleach that has
no additives along with the sodium hypochlorite. In household
bleach, about 5.7% of the product is active chlorine. Even
though this sounds like a small amount, the concentration of
active chlorine in the bleach is very high—about 62,700 mg/L
chlorine.
Many municipal and community water systems use liquid
sodium hypochlorite or gaseous chlorine to disinfect the
drinking water before it enters the distribution system.
Enough chlorine is added to maintain a disinfecting concentration all the way to the farthest locations in the distribution
system. Disinfecting in a building that receives chlorinated
drinking water would boost the existing chlorine concentration
or replenish the chlorine concentration after on-site water
treatment devices have removed the municipal disinfection.
Some municipal water systems use a combination of chlorine and ammonia to create monochloramine for disinfection.
Monochloramine is not as strong a disinfectant as chlorine
and must be used at a higher concentration to achieve a

similar disinfecting power as free chlorine. In a building that
receives chloraminated drinking water, household bleach can
still be used for boosting or replenishing disinfection. However, if monochloramine or ammonia is present in the water,
it will take more bleach to reach the desired active chlorine
concentration than if only chlorine was present.
Active chlorine is referred to as “free” chlorine because it is
not combined with other chemicals and is available to react
with microorganisms. “Total” chlorine refers to free chlorine
plus chemical compounds where chlorine is combined with
other chemicals. When disinfecting with sodium hypochlorite,
the concentration of free chlorine is a measure of disinfecting
power. When disinfecting with monochloramine, total chlorine
is used to estimate the disinfecting power because chlorine is
combined with ammonia, but the measurement of total chlorine also includes any free chlorine and any other compounds
of chlorine that have formed in the water. A better measure of
disinfection power, in this case, is to directly measure monochloramine concentration. However, the Total Chlorine test kit
is more widely used as a convenience.
If it is desired to boost or replenish chlorine in a plumbing
system, chemical injection equipment is needed. Chemical injection equipment consists of a chemical feed pump with
accessory valves for proper operation (Figure 1). A multifunction valve, typically purchased with a chemical feed
20
feature
pump, provides for venting of air trapped in the suction line,
pressure release, provision of required backpressure, and
prevention of siphoning. A foot valve at the end of the suction
tubing in the chemical storage tank prevents backflow of
chemical solution from the tubing back into the tank. A chemical injector is a device with a ball check valve that connects
into a threaded tee in the main pipeline and allows only forward flow of the chemical into the drinking water pipeline.
Additionally, a pulsation dampener and/or a static mixer (a
pipe section with interior vanes) may be necessary for proper
mixing of the chemical into the drinking water. Automatic control of the chemical feed pump can be added by using a flow
meter in the drinking water pipeline that sends an electric signal to the chemical feed pump to dose the chemical based on
flow of the water.
To maintain disinfection throughout a plumbing system,
sodium hypochlorite can be injected at critical locations
where disinfection needs boosting or replenishing. The article, “Critical Locations for Microbiological Growth in Plumbing
Systems” explains that those locations are typically after certain water treatment devices. For buildings fed by private
wells, disinfection is also needed in the well water as it is discharged from the well pump. Refer to the article for more
detailed information as every plumbing system should be
assessed individually for disinfection needs.
Care must be taken in selecting a proper dosage of chlorine for disinfecting plumbing systems. Federal drinking
water regulations demand that free chlorine concentration
stay below 4 mg/L. Many municipal and community water
systems maintain a free chlorine concentration between 0.2
and 0.5 mg/L in the distribution system. Some systems may
go up to 1 mg/L. Dosage of monochloramine in municipal
water systems is typically between 1 and 3 mg/L total chlorine. See Table 2 for a summary of typical disinfection concentrations.

Note: To measure milliliters (mL) of bleach, purchase a container marked in milliliters, called a “graduated cylinder,” from a laboratory supply company. Graduated cylinders come in various
sizes with varied precision of measurement, such as a 10 mL
cylinder marked in gradations of 0.2 mL or a 25 mL cylinder
marked in gradations of 0.5 mL.
Chlorine can break down plastic components used in modern plumbing systems. There is not well-documented information on the chemical compatibility of various plastics and
chlorine, but when asked, many manufacturers of plastic
components that come in contact with drinking water cite the
drinking water regulation of 4 mg/L maximum. However, the
more exposure to higher chlorine concentrations over time,
the shorter the life of the plastic components, so it is better to
stay below 1 mg/L free chlorine.
Resin beads inside water softeners and ion exchange
water treatment devices also break down over time in contact
with higher chlorine concentrations. Manufacturers will allow
the resin to come in contact with 1 mg/L free chlorine for short
time periods, but staying in the lower 0.2 to 0.5 mg/L range is
better for the life of the beads.
The maximum allowable chlorine concentration in hot water
systems is not known. The higher temperatures push the
chlorine to be more reactive, and there is danger that the
chlorine can corrode metals. It is best to stay closer to 0.1 to
0.3 mg/L.

feature
As was noted previously, the concentration of chlorine in
household bleach is very high, so only a small quantity of
bleach is added to water to achieve free chlorine concentrations found in drinking water. Table 3 lists the amount of
bleach that should be added to water to reach drinkable concentrations.
MONITORING WATER QUALITY
To prevent the growth of microorganisms in pipes, the goal
is to provide just enough fresh water and just enough disinfection to continuously expose the pipes to a minimum of
about 0.3 mg/L free chlorine in the water. Routine monitoring
of chlorine concentrations throughout the plumbing system is
necessary to determine if the pipes are getting the proper
exposure to disinfected water.
Field test kits are available for measuring chlorine concentrations in water. An example of a field test kit is the Pocket
Colorimeter™ II from the Hach Company. The test kit can
measure both free and total chlorine concentration. With sodium hypochlorite disinfection, free chlorine concentration
should be measured. With chloramine disinfection, total chlorine concentration should be measured as an estimate of
monochloramine concentration. The instructions for measuring the chlorine concentration come with the field test kit and
are simple to follow. These are relatively inexpensive, simple,
and convenient tests that can routinely guide flushing and disinfection dosing in piping systems.
Unfortunately, the control of microorganisms is a little more
complicated than merely maintaining a specific disinfection
concentration. The conditions in piping systems and water
environments vary, and microorganisms can still grow at disinfection concentrations that are typically effective elsewhere.
Monitoring of “microbiological activity” should be performed in
addition to monitoring disinfection concentration.
The best method of monitoring for microbiological activity
has not been determined at this time. However, one test is
typically used to estimate microbiological activity. It is called
heterotrophic plate count (HPC). The test should be performed by a commercial laboratory that uses a special nutrient in the incubation dish called R2A. There are many laboratories that will perform an HPC test, but not all will use the
R2A. Table 4 lists the criteria that the laboratory should use to
run the test. The tests are about $30 a sample, but overnight
transport to the laboratory should be considered in the overall cost. After finding a laboratory that performs these tests

HPC_R2A Criteria
HPC=Heterotrophic Plate Count
Send sampler sealed sterile bottles containing sodium thiosulfate to
deactivate disinfection.
For analysis, use R2A growth media in the incubation dishes.
Incubation temperature range: 25 to 28°C.
Incubation period: 5 to 7 days.
Run two dilutions: 1 mL sample per dish and 0.1 mL sample per dish.
Run each dilution in duplicate.
according to the criteria listed in Table 4, have the laboratory
send sample bottles for HPC_R2A sampling in disinfected
water. To take HPC_R2A water samples from a plumbing system, the water in the plumbing system must sit stagnant for a
minimum of six hours. It is good to use a similar stagnation
time each time. When it is time to take samples, wipe the
faucet or sample tap opening inside and out with an alcohol
wipe, wiping off any excess alcohol. Open the sample bottle
carefully because it has been sterilized to prevent contamination of the water sample. Do not touch the inside of the bottle, the rim of the bottle, or the inside of the cap. Capture the
first-draw stagnation water in the sample bottle and fill the
bottle to the indicated line. Cap and label the sample bottle.
Put the bottle on ice in a cooler and get the sample to the laboratory within 24 hours.
There is another test that has been found to be a better
measure of microbiological activity than HPC. It is a test that
measures chemical compounds of metabolism (ATP) for
organisms in the water. A second generation method has
been developed, but is not readily available at this time in
water testing laboratories.
SUMMARY
Flushing of pipelines and disinfection of water are the available tools for preventing out-of-control microbiological growth
in plumbing systems. In order to determine the right amount
of flushing balanced with the right amount of disinfection,
water quality throughout the plumbing system must be monitored routinely.
This article describes the details of flushing and disinfecting plumbing systems and testing for chlorine and microbiological activity. Future articles will use this information to suggest a practical approach for building and plumbing contractors for preventing out-of-control microbiological growth in
modern plumbing systems.

FORECASTERS SAY
2012 likely to be a better year
A steady increase in Florida’s population, an uptick in
housing starts and a gradually improving economy should
make 2012 a better year for the stateʼs plumbing professionals. Thatʼs the consensus of several economists who track
Floridaʼs housing market.
“New job creation, rising rents, and the inflow of international buyers are positive factors for the stateʼs housing market,” said Lawrence Yun, chief economist, National Association of Realtors, at the recent 2011 International Real Estate
Congress in Coral Gables. “Today, the
smart money is chasing real estate.”
Floridaʼs population is likely to increase by about 130,000 people in
2012, according to John Silvia, chief
economist, Wells Fargo. In a recent
forecast, Silvia added that tourism and healthcare are leading
the recovery, but other sectors will also be adding new jobs.
New housing starts will increase in 2012, says economist
Sean Snaith, director of the University of Central Floridaʼs Institute for Economic Competitiveness in Orlando. He predicts
about 55,000 new residential starts in the coming year. About
three-fourths will be single-family homes and the rest will be
multifamily construction.
“Nationally, U.S. housing starts are at the lowest level since
the end of the second world war,” Yun said. “America is not
building any homes, even though we are adding 3 million
people a year to our total population. Building activity needs
to triple in order to get back to a normal level.”
However, tight credit for builders and developers, as well as
homebuyers, remains a negative factor for the housing mar-
24
January-February 2012
ket, Yun added. “The inventory of newly built homes is very
low,” he said. “That means builders are selling whatever they
can complete. The problem is that they canʼt get construction
loans in the current environment.”
While housing prices have stabilized in most Florida markets, they are still well below the boom-year peaks of 20042005. Thatʼs because foreclosure sales continue to be a large
part of the stateʼs real estate market. However, Yun said that
lenders are bringing their REO (real estate owned) properties
online gradually, rather than dumping them on the market at
once. In addition, many lenders are recognizing that they lose
less money by approving “short sales” (where the existing
mortgage is larger than the homeʼs market value). Some are
accelerating the sales process or even offering incentives for
owners to move.
For Florida residential plumbing contractors, key opportunities include repairing foreclosed homes and other distressed
properties, as well as additions and remodeling projects. One
trend of note: Some Florida parents are investing their excess
cash by buying inexpensive homes and condos for their 20something children. That allows these Millennials to have a
place of their own that they can “fix up” and decorate themselves.
On the commercial side of the business, new construction
is most likely to occur in the healthcare, retail, and warehouse
sectors. Little new office construction is likely as vacancy
rates are now at 12 to 20% in the stateʼs major markets.
Yun notes that international trade will be one of the driving
forces in the stateʼs economy in 2012. That could create new
commercial opportunities in the stateʼs gateway cities like
Miami, Fort Lauderdale, Jacksonville, and Tampa Bay. As Yun
said, “In Floridaʼs commercial markets, the worst is probably
over.”

SPIRIT GROUP ADDS PRODUCT LINE
LOCHINVAR NEWS
Spirit Group has announced that it now carries the
Keckley product line.
For more information
about the line, visit
.
Demonstrating an ongoing commitment to research and
development, Lochinvar is bringing innovation to the industry
with the introduction of its Armor X2 commercial condensing
water heater which combines stainless steel heat-exchanger
technology with modulating/condensing combustion to deliver thermal efficiencies as high as 96%. Available in models
with 1.0, 1.3 and 1.5 million Btu/hr inputs, Armor X2 offers an
efficient, advanced solution for a wide
range of commercial applications.
Designed to eliminate concerns about
meeting hot water demand, Armor X2 is
equipped with two independent combustion
systems that consist of two 316L stainless
steel heat exchangers, gas valves, and
combustion blowers designed to work in
unison. Featuring Lochinvarʼs exclusive Smart Touch screen
control, which incorporates a built-in cascading sequencer,
allows for sequencing of up to eight ARMOR X2 water
heaters.
Lochinvar also introduces the StratoTherm+ solar thermal storage tank which
offers the functionality of a solar thermal storage tank, indirect water heater and hydronic
buffer tank in a single unit. As solar thermal
energy is added to the copper tube spherical
heat exchanger, heat is introduced to the
stored water. Since hot water is less dense
than cold, the heated water rises to the top of
the storage vessel. The stratified hot water in the top of the
tank permits domestic hot water to be generated instantaneously to meet demand, and an ASSE mixing valve ensures
that the water is delivered at the proper temperature A backup hydronic heat source ensures that the storage vessel is at
a sufficient temperature to simultaneously generate domestic
hot water and meet hydronic heating demands. The StratoTherm+ is available in nine models ranging from 125 to 900
gallon capacities.
Lochinvar recently opened a new distribution center near
Chicago in Elk Grove Village, Ill. With its growth in business
and product lines, the addition is intended to meet increasing customer demand.
Like Lochinvarʼs other
facilities, in Detroit, Orlando, Tampa, Phoe nix, Pompano Beach,
Dallas, and company
headquarters in Lebanon, Tenn., the new warehouse stocks
the companyʼs complete line of water heaters, boilers, pool
heaters, and storage tanks.

Dear Readers,
The election season is quickly approaching. Our industry, our personal lives, and
the future lives of our children are in financial crisis. We have allowed our elected officials on
every level to have too much power over our
financial lives and the debt we owe. If youʼre not
concerned, just check out this site:
How many businesses in this industry can afford
to pay the kind of taxes necessary to make up this
kind of debt in this economy? Itʼs not even possible. This should be enough to shock each one of
us into paying more attention to the responsibilities of our elected officials and the amount of
authority we grant them to have.
