discussions on the design, construction and performance for
piling and ground improvement techniques for building and
infrastructure works.”
“This was the first conference in Australasia that brought
together practitioners from all of the disciplines involved in
piling and foundation engineering,” said Mark Johnson, executive
director of PFSF. “The opportunity to interact with, and
learn from, other professionals in the industry was incredibly
useful to the attendees. We are definitely planning on organizing
a second conference, tentatively scheduled for Sydney
in 2019, and expect to see even more participation.”
The event featured 28 technical presentations and 11 poster
presentations. Keynote presentations included “Challenges
in the Design and Construction of Deep Foundations for
Transportation Infrastructure Projects,” presented by DFI
president Dan Brown, Ph.D., P.E., D.GE, of Dan Brown and
Associates; “Geotechnical Design Considerations for Rock
Socketed Piles,” delivered by Chris Haberfield, Ph.D., principal
geotechnical engineer of Golder Associates in Melbourne;
“Designing Piles for Seismic Events,” by Harry Poulos,
Ph.D., P.E., consultant with the Coffey Group; and “Ground
Improvement by Dynamic Replacement within Intertidal
Mangrove Mud Environment Ichthys LNG, Darwin,” by
Philippe Vincent, managing director at Menard Oceania.
According to Kim Chan of GHD, the technical program
featured “a good mix of technical and practical application
papers, innovation and new products.” Gerhard Zylowski of
Bauer Foundations Australia adds that the presentations
included “a wide range of current geotechnical techniques
and actual applications.”
Second Chance Line Restraint, LLC offers a
safety solution
Tied-back lines can cause serious damage and injury.
Oftentimes, bridge and foundation contractors use multiple
hoisting lines for their cranes on the jobsite. This can potentially
pose a problem when the crane is done doing multiple
line work, such as pile driving. The operator will secure the
lines that are no longer in use back to the superstructure of
the crane to get them out of the way.
What can happen next is that as the operator of the crane
moves on to normal hook work and then booms down, the
tied-back line gets tighter at an unnoticeable pace as the
boom tip moves away from the crane. If the operator doesn’t
remember to slack the tied-back lines, eventually they will
get tight to the laces and can result in damage. More dangerous,
as the tension increases, the weakest link – whether a
chain or nylon used to tie off, or even the structure where the
line is secured – is sacrificed and breaks at an extremely high
breaking strength, which then shoots that line and whatever
rigging is attached to it up to twice the length of the boom.
This also occurs with cranes with high line pull strength, if
the operator engages the wrong lever by mistake. Each situation
endangers personnel, bystanders and equipment.
Second Chance Line Restraint, LLC offers a line tie-back
system that will give the operator and nearby workers a warning;
as the features of the strap are deployed, the stitching is
heard breaking as well as the tightened line slaps against the
boom as the strap reacts, leaving the last component of the
strap containing the rigging from flight.

Selix Equipment Inc. pleased
with NHES performance
Selix Equipment Inc. was very pleased with the reception of
Center Rock (CRI)’s new utility pole hole line cluster canister
drilling system at the National Heavy Equipment Show
(NHES), held in April in Toronto. Pole line contractors from
across Canada were excited to discover a new, economical
solution for drilling utility pole holes in any rock formation.
Born from CRI’s popular conventional LP drills, manufactured
for the construction market, this new cluster canister
solution from CRI is specially made for hole sizes of 18 inches,
20 inches, 22 inches and 22 inches, and offers 9.6 feet of standard
drilling depth, or greater if requested.
With its low weight, ranging from 1,600 lbs to 2,365 lbs,
this utility LP drill is designed to mount on derrick trucks or
installs on any carriers, such as mini excavators, Bobcat skid
steers or any other rotary head drilling system that uses a
standard Hex drive.
This tool will enable any contractor to increase their production
while reducing their operating costs.
The utility LP drill is a canister outfitted with four or five
down-the-hole (DTH) hammers and bits engineered to efficiently
achieve a perfect rock cut true to the bottom in any
soil condition and hardness. Air is delivered to the tool from
a cost-efficient, low-pressure compressor, working all DTH
hammers simultaneously via CRI’s custom air swivel. The
results are always perfect hole dimensions and depths in
minutes, compared to conventional augers, drill and blast
systems, hydraulic hammers or other typical ways of drilling
these holes.
