A Manitowoc 31000 crane was used to lift roof trusses at the new $1.4 billion Mercedes Benz Stadium in Atlanta, Georgia. The 31000 was selected due to its large capacity and small footprint, which allowed it to work inside the tight stadium area. Over 100 lifts of 200-750 tons were planned to install the uniquely designed retractable roof. The 31000 cost close to $1 million to transport and assemble, and will be used on the project for approximately six months.

Power issues initially slowed progress but were resolved through on-site power generation. Segment production and transport have proceeded without issues to support the TBM advance.
Boom dollies are specialized equipment used to transport large cranes over roads safely and economically. They help spread the crane's weight over more axles to meet legal transport limits. While no universal boom dolly design exists due to custom requirements for each crane model, manufacturers have standardized components where possible. Nelson Manufacturing produced the first boom dollies in the 1960s and continues to customize designs. TransWorld also pioneers new solutions like articulating and remote-controlled boom dollies. Proper boom dollies are critical for transporting cranes across different states with varying transport laws.
This document summarizes a large interlocking concrete pavement project at the Port of Oakland in California. The project covered 470,000 square meters and was the largest single installation of mechanically placed concrete pavers in the western hemisphere. Concrete pavers were selected for their flexibility to accommodate various container storage and handling equipment configurations. The pavers were placed over dredged soils, geotextiles, aggregate bases, and asphalt layers to provide structural support and containment of potential leachates from the soils. Layers of pavers up to 1,300 square meters in size were mechanically installed at a rate of 500-600 square meters per machine per day.

"The Load Capacity of Driven Cast-In-Situ Piles Derived from Installation Par...Remedy Geotechnics Ltd
The document discusses a method for estimating the load capacity of driven cast in-situ (DCIS) piles based on installation parameters measured during pile driving. Modern piling rig instrumentation allows parameters like drive energy and advancement rate to be recorded. These parameters can be used to calculate the dynamic drive resistance and correlate it to soil properties like angle of friction. Pile capacity is then estimated using standard soil mechanics equations. The method is illustrated using data from a test pile installed at a site in London. The estimated capacity of 1980kN closely matched the 1947kN capacity observed during load testing, validating the approach. The ability to assess pile capacity in real time based on installation data provides benefits over traditional static analysis methods for DCIS piles

SITE REPORT LIFTING
ACT NOVEMBER 2015
Maxim’s Manitowoc 31000 provides clutch lifting at the
$1.4 billion Mercedes Benz Stadium jobsite in Atlanta.
J
ust when you thought football
stadium design couldn’t get any
more fancy, the rendering of the
new Mercedes Benz Stadium was unveiled
in Atlanta, GA. Global architecture,
engineering and planning firm HOK,
along with tvsdesign, Goode Van Slyke
Architecture and Stanley Beaman &
Sears, designed the new sports venue that
features an impressive array of technology
driven elements, including a retractable
roof that HOK said “provides a radical
departure from the kinetic roofs of other
sports facilities.”
The roof design was derived from the
shape of a falcon’s wing, a reference to
the NFL Atlanta Falcons that will play
in the stadium. “The roof features eight
triangular panels that wrap the stadium
and move in unison along individual
tracks,” HOK said. “This allows the roof to
open and close like a camera aperture.”
Other unique design elements include
360-degree HD halo video boards built
into the roof that offer fans clear views
from every seat. There will be a technology
lounge, a 100-yard bar and a floor-to-
ceiling window view of downtown Atlanta.
As well, exterior lighting can change the
color of the transparent façade.
The 31000 was selected for the job for
a variety of reasons, mainly its massive
capacity combined with its small footprint
and impressive mobility, Ashlock said.
“The 31000 has a small footprint for its
capacity and low ground-bearing pressures
due to four trunnion-mounted crawlers,”
he said. “The crane has extensive mobility,
including the ability to travel with a load.”
The crane’s Variable Position
Counterweight (VPC) system means
that no ground preparation is required as
would be the case for a sled or wheeled
counterweights in other large-capacity
cranes, Ashlock explained.
“The VPC system allows the
counterweights to adjust to an optimum
position depending on the weight
of the load,” he said. “The 31000 has
110,000-pound single line pull and
main load drum line speed of 456 feet
per minute. The crane is available in
combination boom, fixed jib and luffing
jib configurations and has five series of
counterweights for more flexibility for
multiple jobs.”
Ground was broken on the
stadium in May 2014, and
completion is scheduled for 2017.
Stadium jobs are generally
among the most complicated and
expensive. These jobs require the
use of a variety of types and sizes
of cranes, and such is the case
for this new facility. Fittingly the
project has a true “super star”
crane, a Manitowoc 31000 on
rent from Maxim Crane Works.
M.V.P.
With several other cranes from
its fleet working onsite, Maxim
realized the potential for having
such a huge crane on the high
profile project.
“With the economy booming,
the market has created sufficient
demand for this machine,” said
Alan Ashlock, president, southeast region,
Maxim Crane Works. “With Maxim Crane
Works’ coast-to-coast footprint, it seems
like a natural fit for the largest crane
company in the nation to have the largest
Manitowoc crane.”
The 2,535-ton capacity 31000 was
dispatched to the stadium jobsite in
September 2015. The crane was delivered
in 127 loads. There were 24 loads of
custom-designed steel crane mats as well,
Ashlock said.
The steel mats further lower ground-
bearing pressure in the bowl of the
stadium. Ashlock said the matting cost
close to a $1 million.
“The 31000 will be on the job
approximately six months,” he said. “It
is scheduled to be available for its next
project in the second quarter of 2016.”
Once the boom and all the crane’s
components were onsite, it took about 30
days to build the crane.
“This particular erection was
complicated by getting trucks in and out
of a crowded jobsite and working around
multiple other crawler cranes inside the
bowl of the football stadium,” Ashlock
said.
Good ground
Specially designed steel crane mats were
custom made for the project and cost almost
$1 million.
The roof design resembles a big pinwheel,
although the design was said to be inspired
by the wing of a falcon, which is the mascot
for the NFL Atlanta Falcons football team.
The stadium will also be home to the Atlanta
United FC of Major League Soccer. It will
host NCAA basketball tournaments as well as
a host of SEC college football games.

Super star status
Had the 31000 not been available, the
project would have required the use of two
smaller cranes and the need for additional
ground preparation.
As well, without this crane, the
roof components would have been
manufactured smaller, which would have
meant extending the timeline as more lifts
would have been required.
“More lifts would have been higher risk
with multi-crane picks,” Ashlock said. “In
addition, the 31000 offers much more
freedom of mobility around the site.”
Maxim has provided several other cranes
for the project including six Manitowoc
2250s, two 210-ton Link-Belts, two
Manitowoc 888s and two 75-ton rough-
terrain cranes.
The 31000 is rigged with 262 feet of
main boom, 118 feet of luffing jib, series
five counterweights, a 16-part 1,000-ton
load block and two-part 200-ton auxiliary
block. After the crane was assembled and
tested, lift plans were made for all of the
lifts.
“It’s all going great,” said Ashlock.
“The assembly process went smoothly
without any major issues. The first pick is
scheduled for late October.”
Ashlock said the 31000 is currently
sitting inside the bowl of the stadium but
that it will be moving to several locations
around the jobsite for the various roof
picks it will make.
“It will mainly be lifting structural steel
for the uniquely designed roof trusses,”
said Ashlock. “Over 100 lifts are planned
of various pieces ranging from 200 to 750
tons.”
The largest crane the company has
ever built, Manitowoc has produced
two 31000s since the launch of the
machine back in 2005. The first 31000
has been working in South Korea for
the past couple of years. Operated by
Chunjo, South Korea’s largest crane rental
company, the first unit recently was used
for two huge lifts for the expansion of a
petrochemical plant.
Manitowoc worked closely with Maxim
on dispatching the unit to Atlanta and is
very happy to see the crane on such a high
profile job.
“It’s very exciting to see the Manitowoc
31000 working on its first North
American jobsite,” said John Kennedy,
senior vice president of crawler cranes at
Manitowoc. “The timing couldn’t be better
– Maxim had been very interested in this
crane, and the company now has an ideal
project for it to work on. The construction
of this stadium required a crane that had a
very high capacity, but could fit into tight
working quarters.”
The compact footprint of the 31000,
which is enabled by its Variable Position
Counterweight (VPC), has allowed the
company to position the crane inside of
the stadium while it works, something
other large crawlers would not be able
to accomplish, Kennedy explained.
Additionally, the crane’s size does not
require the same degree of ground
preparation that other large capacity
cranes would require, which is saving
Maxim both time and money.
The use of this crane has generated a lot
of interest.
“We certainly plan to build more 31000s
in the future and believe that demand
will only rise when other companies see
how well it’s performing on this project,”
Kennedy said.
“This project showcases that the
31000 can be used on commercial
or infrastructure projects as well as
petrochemical, chemical, pulp and power
plant applications,” Ashlock said.
General contractor on the project is
Holder Hunt Russell Moody (HHRM)
joint venture. Maxim is working for Derr
& Isbell Construction. ■
