APPLIED
FOUNDATION TESTING, INC. PERFORMS LARGE-SCALE LATERAL OVER-WATER
TESTING
In February
of this year a new Statnamic record was set for the largest lateral
load. Applied Foundation Testing of Green Cove Springs, Florida
achieved a lateral force of 823 tons (7.34 MN) on a pile cap at
the Pascagoula River in Mississippi. The customer was the Mississippi
DOT, and the testing was performed in conjunction with Dan Brown
of Auburn University, and Gray Mullins of the University of South
Florida. Schmertman & Crapps of Gainesville, Florida designed
the load test program, and Dr. David Crapps supervised the testing.
A total of 15 tests were performed. A 120 ft (40 m) barge was used
as a runway for the Statnamic reaction masses as they were thrust
off the pile cap. Berminghammer's 14MN Statnamic device and reaction
masses were used, while AFT provided a special 'sled' to cradle
the reaction masses and a 'jib' to support the Statnamic piston.
This testing
was used to check the design of the pile cap in response to a dynamic
load, such as a ship impact. Loads of over 1000 tons are possible
with this same equipment, and larger Statnamic devices could be
used for even larger lateral test loads. Congratulations to AFT
on this groundbreaking achievement!
DIAGNOSTIC ENGINEERING CONSULTANTS LTD.
INTRODUCE STATNAMIC TO TAIWAN
On November
12th, 1997, Diagnostic Engineering Consultants Ltd. performed the
first Statnamic test in Taiwan. The test was conducted on a 900
mm bored pile at the site of a large incinerator project in Taipei.
A 16MN Statnamic device was provided by Fugro Geosciences Ltd. of
Japan, and the testing was performed under the direction of Fugro
and Berminghammer. On November 15th, a second 16MN test was performed
on an adjacent pile. The piles were 50 m long, and were primarily
friction piles founded in clay.
DECL constructed
a new gravel structure, base frame, and reaction masses for the
16MN testing in Taipei. They will use this same equipment with their
new 20MN Statnamic device which is scheduled to be delivered in
August of this year.
GROUND ENGINEERING PERFORMS TESTING IN
SYDNEY, AUSTRALIA
Ground Engineering
of Sydney, Australia have started testing with their new 16MN device.
On April 21, 1998, they performed an 8.7 MN test on a bored pile,
installed by Franki at the site of the Olympic Village, near the
new Olympic Stadium. On April 23, GE performed a second test on
the same pile as part of a demonstration day attended by over 70
engineers. The site was operated by the Mervac Lend Lease Village
Consortium. The test pile was instrumented with three strain gages,
which were monitored by Sydney University. The testing was well
received by the audience.
FUGRO GEOSCIENCES AND TAMA BLASTING INTRODUCE
30MN DEVICE TO JAPAN
The first Statnamic
test with a 30MN device in Japan was conducted on March 5, 1998.
The pile was a 1.5 m diameter pipe, 46 m long. The pile was tested
to a load of 23 MN. A second test was performed on March 9, and
a third on March 12. Although these three tests were the largest
Statnamic tests in Japan, the companies involved were no strangers
to Statnamic testing. This 30MN device, the 4th of its kind, is
jointly owned by Berminghammer, Fugro Geosciences Ltd., and Tama
Blasting Engineering Construction. These companies already own a
16MN device (Fugro) and an 8MN device (Tama). The 30MN joint venture
is being managed by Makoto Tsuzuki of Fugro Japan, Inc.
This 30MN project
was part of the expansion of a container terminal in the Port City
of Nagoya, Japan. The testing was performed jointly by Fugro and
Tama. The customer for these Statnamic tests was the Japanese Ministry
of Transportation. It is expected that this 30MN testing will help
to elevate the profile of Statnamic testing in the Japanese market.
Although Statnamic has already enjoyed great success in Japan, it
is anticipated that 1998 will be a year of even greater Statnamic
activity.
Congratulations
to Fugro Geosciences Ltd. and Tama Blasting!
UNIVERSITY OF SOUTH FLORIDA/FHWA INTRODUCE
4MN HYDRAULIC CATCH MECHANISM TO THE UNITED STATES
On February
10, 1998, the first 4MN Statnamic Hydraulic Catch Mechanism was
demonstrated in Montgomery, Alabama. The test was viewed by more
than 100 Alabama State Engineers. Dr. Gray Mullins of the University
of South Florida (USF) directed the testing with assistance from
Applied Foundation Testing. The unit performed 2 demo tests.
This catch mechanism was built to operate in conjunction with the
4MN Statnamic device owned by the Federal Highway Administration
(FHWA). Dr. Mullins plans to work closely with the FHWA in Statnamic
research. The unit is also intended for Statnamic demonstrations
for State Departments of Transportation. The University of South
Florida will derive some revenue from the equipment by renting it
to AFT for use with their own 4MN device.
On February
11 and 12, the catch mechanism was moved to a research site at Auburn
University where 6 tests on 2 different piles were conducted. This
testing was performed for Dr. Dan Brown of Auburn. On Monday, February
16, the equipment was setup and ready for testing at USF in Tampa,
Florida - it's 3rd site in less than one week! In April the device
travelled to the University of Massachusetts, Lowell, near Boston,
where it performed 7 tests on drilled shafts. This testing was part
of a research project being undertaken by Dr. Sam Paikowsky, who
directed the testing. The 4MN Catch Mechanism has performed beyond
it's original expectations and will soon revolutionize pile load
testing in the United States!
AFT BEGINS STATNAMIC TESTING IN THE US
PRIVATE SECTOR
Applied Foundation
Testing, based in Florida, has had a busy first-half of 1998. This
new company has recently introduced Statnamic testing to the private-sector
in Florida. Since January of 1998, AFT has performed 24 Statnamic
tests on 5 different private sector jobs, essentially opening a
new market. These tests are in addition to 20 tests and demos to
date for various State Departments of Transportation, including
Florida, Alabama, North Carolina, Mississippi, Missouri, and Iowa,
with testing scheduled for Virginia in July. In June of this year,
AFT completed a successful testing program in New Bern, North Carolina
on the Neuse River Bridge. On this job, three drilled shafts were
tested to loads of up to 13.5 MN using a 14MN Statnamic device (supplied
by Berminghammer). The contractor was Traylor Brothers and the owner
was the North Carolina Department of Transportation. AFT has work
planned with the Mississippi DOT using the 14MN device for over-water
lateral load testing. Loads of up to 8MN are planned for this job
which is set to go this fall. AFT also has an upcoming 30MN job
for the Florida Department of Transportation. Six 30MN tests are
planned on a the 17th Street Causeway in Ft. Lauderdale. Berminghammer
will supply the device.
AFT PERFORMS 30MN OVER-WATER TESTING IN
FT. LAUDERDALE, FLORIDA
Applied Foundation
Testing recently began a 30MN testing program in Ft. Lauderdale,
Florida. Testing was performed at the site of the new S.E. 17th
Street Causeway Bridge. The first test was completed on May 2nd,
with an applied load of 30.7 MN. A second test was performed on
May 17th with an applied load of 30.5 MN. Both tests were conducted
over-water. Four additional 30MN land-based tests are planned for
the project. The drilling contractor was Gimrock Construction, and
the general contractor was Traylor Brothers. The owner was the Florida
Department of Transportation. Berminghammer and Sambo Total Service
Foundation Construction, of Seoul, Korea supplied the testing equipment.
The foundations
tested were 48" (1.22 m) drilled shafts, approximately 30 m
in length. All test shafts on the site included strain gauge instrumentation,
and several shafts also include an Osterberg Cell at the toe. Both
shafts tested thus far behaved elastically.
PRECISION MONITORING & CONTROL - CONTINUED
SUCCESS WITH 3MN
Since taking
delivery of their 3MN with Hydraulic Catching Mechanism, Precision
Monitoring and Control of the UK has performed load tests numbering
in the hundreds! Despite unprecedented success in the UK, PMC has
not shied away from venturing into other markets. In the last 6
months they have teamed with TNO to perform testing in Holland,
as well as Asqalan Construction & Development to perform testing
in Abu Dhabi in the U.A.E. Details are given in the following articles.
PMC AND TNO PERFORM TESTING IN HOLLAND
In November
of 1997, PMC and TNO collaborated on a testing job in Arnhem, Holland.
A total of 31 load tests were completed, ranging between 1.3 MN
and 3.0 MN. A total of 8 piles were tested in two days, with as
many as 7 cycles on one pile.
PMC MIDDLE EAST AND ASQALAN INTRODUCE STATNAMIC
TO ABU DHABI
In April of
1998, PMC Middle East, of Dubai, teamed with Asqalan Construction
& Development to perform 2 demonstration tests in Abu Dhabi
in the United Arab Emirates. The pile tested in the demo was a CFA
pile that was installed by the contractor NSCC. The first load cycle
was taken to 1.5 MN and the second cycle was taken to 2.7 MN. The
demonstration was well attended by the local piling community, and
it is hoped that Statnamic will soon become popular in the U.A.E.
