>> Male narrator: He also developed design
procedures for establishing continuity and pre-cast,
pre-tension concrete members by using mild reinforcing steel.
Further West, George C. Hansen, a structural engineer with
Phillips Carter Osbourne in Denver contributed design
criteria for pre-cast, pre-stressed members.
From fabrication, to the construction applications,
he also developed lone tables and brochures
for pre-stress members.
Over the years, continued advances in pre-stress concrete
led to the need for a central organization to unify
and advance the industry.
An early informal association was created among the first
pre-stressing companies.
Ultimately, six Florida manufacturers joined to form
the pre-stressed concrete institute on June18, 1954.
Those six companies were Cone Brothers, R.H. Wright and Co.,
Dura-Stress, West Coast Shell Corp.,
Lakeland Engineering Associates, and Lakeland Concrete.
They created six classes of members.
Active for pre-stress companies, associate for
related businesses, professional for architects and engineers,
junior for professionals in training, student for those
in architectural and engineering colleges,
and honorary as designated by the board.
Right from the start, PCI's founders recognized they
weren't creating just another trade association.
PCI would be an organization directed by the
active participation by the professional engineers.
This unique combination of producers, suppliers and
professionals nurtured the growth and vitality of the
pre-stress concrete industry and led to become what it is today.
Douglas P. Cone was elected PCI's first president.
George Ford served as vice president.
While Harry Edwards was named Secretary treasurer.
These men, along with the organization's directors,
established four objectives for PCI.
One, develop standard specifications for
pre-tensioned products for designers and engineers.
Two, conduct full-scale fire tests of roof
and floor-slab products.
Three, develop and promote standardization of
beam sections for bridges.
And four, produce a technical journal and newsletter.
These goals were quickly achieved.
PCI released its first industry standard, specifications for
pre-tensioned bond and pre-stressed concrete products
on November 7, 1954.
As progress continued, the group held its first annual convention
at the Lagomar Hotel in Fort Lauderdale Florida
on April 21st and 22nd, 1955.
More than 300 engineers, designers, contractors,
and producers attended.
In 1955, PCitems debuted as a monthly periodical.
It was followed in May 1956 by the quarterly PCI journal.
Now a bi-monthly, it remains one of the premier
communication vehicles of the pre-cast concrete industry.
On September 1st, 1956 PCI created a
permanent headquarter staff when colonel Martin P. Corn
a former consulting engineer was appointed
PCI executive secretary.
The organization opened its temporary headquarters,
in Boca Raton, Florida.
Three years later, the Florida Pre-stress Concrete Association
was formed to promote the material locally.
PCI headquarters moved to Chicago in December 1959
where it remains today.
But while the headquarters has remained in one place,
the industry has moved ahead with breathtaking speed.

Today, architects and engineers continue to advance the
industries capabilities using new technologies and ideas
to stretch design parameters.
Recent advances include breakthroughs in
seismic techniques that will expand the uses of
pre-cast concrete nation-wide.
Ultra high performance concrete that will expand the durability
of pre-cast concrete to 30,000 PSI and beyond.
Self-consolidating concrete that will produce higher strength,
faster production, and better aesthetics for
all types of projects.
And all pre-cast bridges with beams, deck slabs, peer-caps
and columns.
These components an be used to replace bridges
on rapid schedules.
Where will pre-cast concrete take the construction industry
in the next 50 years?
The answer lies in the dreams of today's architects,
engineers, producers and suppliers as they continue
to stretch the boundaries.
Their work will be nurtured and strengthened by the
encouragement, promotion, resources, and expertise of the
pre-cast, pre-stressed concrete institute.
After 50 years, the best is yet to come and it begins today.
