INNOVATIVE TECHNIQUES
AND MATERIALS
MERCEDES-BENZ STADIUM
ATLANTA

* Steel management - 30+
steel fabricators across North
America were employed to meet
the demands of changing steel
members and recover from missed
production windows due to late
design changes.
* Digital security badging system
- On-site workers used digital
badging and scanning to track onsite personnel.
* 4D logistics and crane
sequencing - To optimize the
demand for field area crane
access, HHRM JV used 3D and
4D modeling via Revit, BIM 360
Glue and Synchro to produce 3D
visual controls of crane reaches and
workflows.
* BIM/VDC - Weekly and daily
design/trade contractor coordination
sessions using BlueBeam Studio
with live markups to record actions,
fast-forward solutions and allow
days-later fabrication and installation
of work were held throughout
design and construction phases.
* Ethylene Tetrafluoroethylene
(ETFE) - On-site mockups, 3D
BIM and key work sequencing were
used to implement the state-of-theart ETFE skin. ETFE is a copolymer
of ethylene and tetrafluoroethylene,
refined from seawater. The durable,
highly transparent, lightweight film
generates 95 percent of the light,
while weighing just 1 percent of
glass structures.
* 4D Sequencing - 3D and 4D
(3D + time) digital modeling best
practices developed time-based
animations of key work flow
sequences for key systems such as
concrete sequencing, steel erection,
operable roof, MEP staging, crane
and shoring tower sequencing, and
other logistics.
* Roof Mechanization - Despite
several operable roofs having been
completed in recent years, none
had yet used an eight-segment,
aperture-style approach. HHRM
JV captained mechanization
contractors, steel fabricators,
roof and skin contractors, and
an army of digital scanners and
layout specialists to integrate the
complementary systems and ensure
roof operation.

PROJECT TEAM

Owner: Georgia World Congress Center (GWCC)
Developer: Atlanta Falcons Stadium Company (Stadco)
Developer's Project Executive: Darden & Company
Contractor: Holder, Hunt, Russell, Moody, a Joint Venture (HHRM)
Design Team: HOK
Because of the importance of steel to
the project, a Steel SWAT team was established. The prime SWAT included HHRM,
the designers and the lead steel contractor,
explains Wadsworth. "The SWAT integrated five structural engineering design
entities, more than 32 steel fabricators,
erectors and inspectors, which was no
small feat," he says. "It was simple logic
that the only way to reduce information
loss and non-value time lag - like time
spent waiting for approvals - was to focus
and expedite."
The Steel SWAT team was assigned
a conference room in which to work and
meet. Meetings occurred on a daily and
weekly basis to keep the focus in the right
places. "We had spreadsheets, databases,
tracking logs, and a hierarchy of reporting
tools and mechanisms to be able to report
on the status of each piece, by segment,
at a moment's notice," says Wadsworth.
"We made factory visits, site visits, inoffice visits to engineers and detailers,
and reported on RFIs, bulletins and other
critical documents for over four years."
This is not the first time HHRM has
established dedicated teams with one
focus. "The complex nature of design and
construction can create unintentional gaps
or diffuse attention," says Wadsworth.
"We've found that assembling a singularly
focused group to own all aspects of certain
processes can help because they wake up

each morning with no other purpose but to
focus on this singular challenge."
"We did use some new strategies,
such as owning and managing a developer decision log to keep issues in front
of them that were, in a sense, precluding
design from being finished, and procurement and construction," says Wadsworth.
HHRM also helped with design management and at one point had three licensed
architects dedicated on-site to assist with
communication and coordination, and to
help schedule and prioritize design efforts
to keep up with construction.
Communication and conflict resolution throughout the construction process
of a complex project are critical. "We set
up a communication-conflict resolution
hierarchy," explains Wadsworth. Weekly
principals' meetings were held, but only
the highest issues would be brought to that
group. "We also had joint venture meetings, design meetings, hot list meetings,
trade coordination meetings, and the list
goes on. We even had spreadsheets and
calendars to track the regular meetings."
Mercedes-Benz Stadium faced never
seen, seemingly insurmountable obstacles in design and construction over its
several-year gestation, says Wadsworth.
The HHRM JV team, with client and partner buy-in, rose to the occasion. He adds,
"This stadium has redefined both the fan
experience and Atlanta's skyline."
