One of our most recent
and perhaps most difficult challenges was the complete renovation of a 40
year old pool at the United States Air Force Academy in Colorado
Springs, Colorado. The obstacles that IPCI was confronted with were very
unique and complex. Both IPCI's many years of custom product design
experience and earlier hands-on field construction experience proved
extremely valuable in finding innovative solutions, making this one of our
most successful projects.
The pool was designed with
pipe tunnels, which go around its entire perimeter.
The pool structure is reinforced poured in place concrete.
The decks within the natatorium space consisted of two layers.
The first layer was a 6 inch thick structural slab suspended from
the foundation walls to the pool walls forming the roof of the tunnels. There were insulation and radiant heating coils placed on top
to the structural deck and a second deck 4 inches thick was placed on top of
that with a thick set tile finish. This
existing situation had significant structural inferences, which strictly
inhibited the design window of the new gutter system. The problem was further compounded by the fact that the
gutter had to comply with the NCAA requirements for competition, which
means the pool water had to be maintained at the gutter rim during
competition and not allow for any water rebound back into the pool.
owner requested that all 26 underwater lights in the pool
be removed and sealed water tight and then have new pool tile
overlaid to match the new pool interior. Removing the light fixtures and
making the fixture openings (2 feet in diameter) watertight was a very
intense procedure. One of the
most difficult undertakings is to keep any underwater wall penetration
from leaking. IPCI engineered a mechanical window well sealing system. The
system incorporated a flexible gasket mechanically compressed by a large
stainless steel plate. The
poolside face of the stainless steel plate had a grid system of ½ inch
stainless steel rebar welded to it and a weld stainless wire fabric welded
to the rebar. A special high
strength permanent epoxy masonry grout finish was trawled over the old
window opening so that the new pool tile could be affixed to it.
The new gutter system required completely changing the configuration of
the old gutter without affecting the structural integrity of the existing
pool wall bond beam or the existing gutter stainless steel rim, which is
used to carry the pool bulkheads. IPCI developed a unique custom gutter
profile, which accomplished both. IPCI
then developed a gutter water evacuation system by core drilling 5 inch
diameter vertical holes in the beam directly over the abandoned underwater
light wells. IPCI then designed a special plumbing pipe fixture to fit in
each hole and permanently seal it. These fittings were then connected to a
14 inch diameter PVC pipe manifold that carries the pool gutter water back
to the filter system balance tank. This design exceeded the NCAA
requirements for the carrying capacity during competition and handles both
static and dynamic surge with no problem.
The existing filter system was removed. This system consisted of four 8 foot diameter copper lined
steel tanks which were twenty-five feet long.
IPCI designed a new stainless steel filter system consisting of
only two filter tanks occupying only 180 square feet, which occupies
approximately 23% of the old filter system footprint.
The new vacuum sand filter system saves the owner on heating costs,
chemical costs, makeup water costs, reduces overall maintenance and daily
The newly designed chemical treatment system, which consists
of bromine, ozone and carbon dioxide, creates excellent water quality and
eliminates the unpleasant odors which are often present in indoor
natatorium facilities. The new chemical system automatically evaluates the
pool water quality and feeds the required amounts of chemicals. This automation, as well as all of the other electronic and
monitoring equipment, are installed in a custom designed control package
so that all the pool operations can be performed and monitored from one convenient
of the project documents for design and construction had to be done in
strict compliance with military and government regulations.
Since this job has been completed, IPCI has been awarded three
additional contracts at the Air Force Academy.
One, for the rehabilitation of the Cadet Intramural Pool, which is
60 feet wide by 120 feet long and 7 feet deep with a total gallon volume
of 377,000. This design was
completed last year. IPCI is
currently doing a redesign of the Air Force Academy Officers Club pool,
which is being completely reconfigured and is having a water playground
added for children. IPCI is also doing a bulkhead addition to the natatorium
pool, which is currently in progress.
