Full Day Seminar
Helical Piles; When, Where & How?
Norwich Holiday Inn, Norwich, CT (Only 6 mi. from Mohegan Sun Casino)
Tuesday, April 24, 2012

Seminar Content
The helical pile system is a segmented
deep foundation system with helical
bearing plates welded to a central shaft.
Load is transferred from the shaft to the
soil through helical bearing plates. As a
result of their true helical shape, the helices
do not auger into the soil but rather screw
into it with minimal disturbance.
The first section, called the lead section,
contains the helical plates. The lead section
can consist of one to four helices. If
required, additional helices can be added
with the use of helical extensions.
Plain extensions are then added until the
lead section penetrates the bearing strata
and the necessary or appropriate torque is
achieved. The true helix geometry of each
steel bearing plate minimizes soil
disturbance during installation.
The helical pile foundation is preferred
over driven piles, drilled shafts, grouted
tendons, auger-cast piles, belled piers and
other deep foundation systems for a
number of compelling reasons:
- Fast installation and immediate loading
- Pre-Engineered
- Eliminates high-mobilization costs
associated with driven piles, drilled shafts
or auger cast piles.
- Instant torque-to-capacity feedback for
production control.
- Easily modified in the field.
- No need for concrete to cure.
- Uses common construction equipment
easily fitted with hydraulically-driven
torque motors.
- Easy to use in limited access sites, high
water tables and weak surface soils.

Speakers
FEATURED SPEAKER: George W "Pat" Haffert, a sales & marketing
professional for 37 years, has worked for Danbro
since 1999. Pat has over 135 hours of instruction/
training on helical piers and has been Chance
certified since 1999. He has presented or
participated in 200+ presentations to well over
2,000 Engineers and Architects. Pat is a member
of the Helical Pile Association, Chance Alliance
Network and the Deep Foundations Institute.
Charles E. Elias, P.E., has worked as a civil and
structural engineer for thirty years. Over that
period, site design issues, such as soils and
drainage have become critical to the approval
process of successful development projects. His
design experience includes many projects, from
residential to large subdivisions and shopping
mall sites, as well as sitting on various local land
use boards.
Howard Epstein, Ph.D., P.E., is a recognized
authority in structural engineering with nearly
one hundred published technical papers in the
field. Howard is a professor in UConn's Dept. of
Civil and Environmental Engineering, a Fellow
in the American Society of Civil Engineers and
recipient of CSCE's Benjamin Wright Award for
lifetime achievement.
George Torello Jr., P.E., N.A.F.E., a structural
engineer with 50 years of hands-on experience in
the design, review, and inspection of structures.
George was the recipient of CSCE's 2001
Benjamin Wright Award for lifetime
achievement. George specializes in the
investigation of building failures. Frequently
called upon to provide expert testimony, his
extensive background in the analysis of building
failures is an important ingredient in our design of
new structures and in the evaluation of soils
underlying foundations.
