John Lawrie Tubulars, a specialist
supplier of steel tubulars for piling for the
construction industry, has expanded its
services nationally. It recently added a new
yard, expanded existing sites and added
new equipment to better service the
construction market.
In May, the company opened Phase 1 of
a new 8 acre (3.2 hectare) yard in Camden,
New Jersey, to complement its existing five
sites across Texas, Colorado, New Jersey,

Pennsylvania and Oklahoma. This new
yard includes a 123,000 sq ft (11,427 sq m)
warehouse, a 5,000 ft (1,524 m) garage, as
well as office space.
In August, groundwork commenced on
Phase 2 of its Northeast expansion,
extending the Camden site by another five
acres (2 hectares). The new acreage near
transportation links provides additional
capacity to store thousands of tons of pipe
for ready shipment to U.S. clients. Plans are

To achieve proper design strength in any
drilled and grouted hole, the bar or
tendon must be centered in the drilled
hole to assure proper grout or concrete
coverage throughout the design length
of the element. Pieresearch, a long-time
industry leader in alignment/centralizer
products for the deep foundations
industry, has developed a new, adjustable centralizer for auger cast
pile, micropile, soil nail and tieback installation. The adjustable
quick-lock unibar centralizer is the answer to uniform spacing
requirements across a wide range of diameters. Three different new
parts are available to fit shafts ranging from an O.D. of 10 to 24 in
(25.4 to 50.8 cm). All are adjustable to fit bar sizes #6 through #18.
The new unibar centralizers are made of lightweight, durable,
noncorrosive plastic and consist of two identical halves that are
quickly and easily snapped together. The adjustable centering
device will accommodate single bar, single and multi-strand
anchors and encapsulated anchors (DCP), and are suitable for steel
or plastic pipe applications. The adjustable unibars can be attached
with zip ties or tie wire, and are offset to fit between rebar threads.
They are lightweight, economical and do not require nuts or bolts
for installation.
Pieresearch will ship these made-in-the-U.S. products directly
to any location.

also underway for a Phase 3 expansion in
the fourth quarter of 2020. The expansion
will involve converting a warehouse to a
full-service fabrication operation for
cutting, beveling, and welding pipe to
exact client specifications.
In Houston, at the supplier's headquarters, work is also underway to develop
on-site facilities including over $1.5 million
of investment in capital equipment that will
be fully operational by the end of
September. The additional equipment has
created 10 new jobs. An additional $1
million of capital investment in equipment
is planned by December 2020, to go along
with continued heavy inventory investment
at all locations to give customers greater
product selection of sizes, walls, and grades
of domestic steel pipe.
John Lawrie Tubulars' capabilities for
supplying products to the pipe pile,
micropile and helical pile industry include
an inventory of over 90,000 tons of readyto-ship steel pipe across its locations. Inhouse services include beveling, plasma
and saw cutting, splicing to length,
inspection, as well as cleaning, blasting,
profiling and adding end plates.

Grout Systems was contracted to design and
install 898, 16 in (40.6 cm) diameter auger
cast piles, each 45 ft (13.7 m) in length for a
total of 40,410 l ft (12.3 km) to support the
Headworks Facility Structures at the Water
Reclamation Facility in Akron, Ohio.
The existing main outfall sewer that runs
through the headworks building was
constructed in 1927 and remained in service
during the installation. Due to the sewer's
age, it was crucial to not disrupt its operation.
There was also a need to excavate in close
proximity to it. These factors were
considered when evaluating the proper
foundation support. Grout Systems was contracted to design and
install an additional 330, 16 in (40.6 cm) diameter auger cast piles at
the same length as above for a total of 15,030 l ft (4.58 km). Many of
these piles were drilled and grouted within inches of the sewer.
All piles were installed in up to 37 ft (11.3 m) of uncontrolled fill
near the Cuyahoga River. Due to encountering obstructions,
locations became problematic, but issues were overcome. This
resulted from extensive load testing to 3x design, and the use of stain
meters that were implemented to interpret unit skin friction in
differing soil zones. Grout Systems believes that the auger cast pile
was the most economical, safest installation choice.
