lifting something that large from 400 feet above the street  
would require planning,coordination,special equipment,  
machinery and a dedicated team.  
Call it what you will—big, jumbo, over-sized—these  
massive panels aren’t a trend. Glass keeps getting big-  
ger to satisfy architects’ desires for spans and spans of  
uninterrupted facades. The results are impressive, but  
their execution is not easy. From the design to produc-  
tion, fabrication and installation, these projects require  
a comprehensive, well thought-out plan. And you’ve got  
to be all in.  
It Starts With a Plan

Steel Encounters, also of Salt Lake City, was the con-  
tract glazier. According to president Tom Jackson, the  
project called for a unique, carefully planned approach.  
The company’s work began more than a year in advance  
of ever being on site. To date, it’s the largest glass with  
which his company has ever worked.  
As part of the design-assist project, Jackson says  
early coordination, communication and teamwork were  
critical. The company’s installation plan began with re-  
view of the architectural drawings and site plans to help  
determine what type of equipment would be necessary

for the installation. Steel Encounters  
worked closely with its glass supplier,  
Germany-based sedak (see sidebar on  
left), on how the glass would be pack-  
aged and shipped, unloaded, the equip-  
ment needed and to gain an overall  
understanding of the project. Several  
trips to visit the fabrication facility  
in Germany were made. This allowed  
them to see not only the production of  
the glass, but also how it was handled,  
packaged and transported.  
Sedak designs its own wooden crates for shipping, and makes sure that  
height and weight restrictions for the shipping company are matched  
when they are packed.  
From Point A to Point B  
Transporting jumbo-sized glass from  
Germany to Utah isn’t a simple task.  
This, too, requires a lot of planning and  
coordination to ensure the shipment ar-  
rives on time and free of damage.  
From Here to There: Fabricating,  
Handling & Transporting Jumbo Glass  
Currently, the largest fabricated glass in the world is made in Europe by  
the German company sedak. Before transporting and shipping to the contract  
glazier, the jumbo units must move--throughout the factory, and onto trucks,  
boats and possibly other means of transport before reaching the jobsite. For  
this purpose, sedak built a semi-automatic transport and storage rack system.  
Glass packaging is a major  
“Because the glass was too large to  
fit into standard high-cube ocean con-  
tainers, the manufacturer modified  
open-top containers, adding 2 feet to  
accommodate the glass,” Jackson says.  
Once crated, the glass was loaded on  
to a barge for transport by river to a  
seaport,where it was loaded on a cargo  
ship for the transatlantic shipment to  
New York City and then transported  
via rail to Salt Lake City.  
“In order to protect the glass and  
keep it clean and pristine until delivery  
to the jobsite, we rented a warehouse  
with an overhead crane where we un-  
loaded and stored one dozen contain-  
ers of glass,” says Jackson. “Careful  
consideration and planning went into  
finding the proper location where we  
could back the oversized loads through  
the overhead door and under the over-  
head crane to unload. We engineered  
and built custom steel racks to store  
the glass. We received and staged 90  
percent of the glass in that warehouse  
before [installation] began.”  
At some areas it’s handled fully automatically and only on a few stations  
is the glass] supported manually with special suction cups,” says Rana Far-  
man, a sedak project manager.  
We decided to design and build our own wooden crates, based on design  
and size of the pieces,” she says, explaining that when the logistics depart-  
ment packs the crates they make sure that height and weight restrictions  
for the shipping company are matched. She says crates are only used when  
the glass leaves their facility. The glass may be stored on an A-frame inside  
a wooden crate or, if necessary, within an open-top container.  
When it comes to shipping, the company has developed its own system to  
make sure that all pieces, whether regular or oversize, arrive on site without  
any interruptions or cracks. Farman says each piece of glass and each proj-  
ect is different so each needs different packaging.  
“The sedak truck will deliver it to the harbor or airport, depending on which  
freight option was chosen by the client,” she says, adding that in the U.S. it  
might be transported on a flatbed truck to ensure it meets height restrictions.  
In collaboration with a freight forwarder and the airport/harbor facility, the  
crates are moved out of the containers/planes with special lifting devices,”  
says Farman. “Due to the weight and height, most of the time sea freight is  
the only option.” One exception, she says, are glass fins with an overall length  
up to 15 meters (49.2 feet).  
Glass over 40 feet is delivered in wooden crates from “roll-on-roll-off ships”  
with MAFI trailers. She says when secured by sedak-attached slings around  
the crates, moving those enormous pieces will be a little easier.  
Jackson says the glass was so large  
they also built a custom trailer for  
transporting the glass to the jobsite.  
It was capable of holding two pieces  
of the 10-by-35-foot glass. Another  
engineering design consideration  
To make sure our clients know what to expect, packing lists including  
each crate piece with overall height and weight are provided before arrival  
on site,” she says.  
If necessary, they will also suggest needed equipment, such as a suction  
cup machine to support overweight pieces.  
For storage, Farman says warehouses should have easy entrance access  
and, preferably, a moving crane system installed.

Main Considerations When  
was building a trailer to withstand  
high windloads. As Jackson says, “We  
couldn’t have a trailer blow over with  
the glass on it.”  
And when it came to getting the glass  
from the warehouse to the jobsite,Jack-  
son says his company even planned for  
the smoothest delivery route.  
Installing Jumbo-Sized Glass  
Having recently completed the jumbo glass installation on 111 Main  
in Salt Lake City, Tom Jackson, president of contract glazier Steel  
Encounters, offers a few best practices for success.  
Have the right equipment.  
Study the drawings and logistics to be sure you  
have the right equipment.  
Coordinate, Communicate  
The plan on how to install the glass  
and the type of equipment that would  
be used was something the team  
worked on long before they were ever  
even on the jobsite. Jackson explains  
that due to tight space at the jobsite,  
an early decision was made to use the  
project tower crane located 400 feet  
above the street to install the glass.  
Communicate with the installers.  
Make sure they understand what they’re doing and walk through  
the process carefully, even rehearsing it—that’s critical.  
Communication with vendors regarding quality.  
Quality needs to be vetted out thoroughly before  
the glass ships.  
“If you have defective glass and you don’t realize it until installation, the  
cost to deal with it can be astronomical,” says Jackson. “It’s worth going  
to the factory and seeing the glass and how it’s packaged, determin-  
ing what’s acceptable and certifying first hand you’re getting what you  
expect to get.  
We also made another unique  
equipment decision because the face of  
the lobby glass wall was inset 5 ½ feet  
from the exterior of the tower above,  
which required a custom motorized  
counterbalanced jib to push the glass
