Transcripts
this will be the greatest stadium built
to date the architecture you look left
right up down so if I stadium has
everything I've been fortunate to be out
here the entire time of the construction
of this project I can still remember
when I flew out here fall of 2016 and
it's been a real treat for all of us
here on the team to be out here every
day and see this thing evolved from its
original site to the 100 foot deep hole
to here today we're getting an up-close
look at sofa Stadium as it enters the
final stages of construction the first
part is really the design you know the
design process usually is over a
two-year period I mean we have drawings
that we've issued for construction that
if they were on the floor they would
come up to here and they're complicated
buildings like 70,000 people in a three
four-hour window all coming in same time
that doesn't really happen to that scale
to that degree on any other building
type since the Roman Colosseum 2,000
years people want to be in the building
they want to be part of the building
they want to experience the building
they want to watch the teams there the
architecture in the buildings have been
not flatlined but they've been sort of
this common type look and feel and all
the focus has been on the green grass
and on the playing surface
so what we do is we do a very deep dive
into the region what does it mean to be
an Angelina what kind of lifestyle how
that can all become embodied into an NFL
venue I think there's two big challenges
right off the bat that we as a design
team you know gave a little positive but
how are we gonna tackle these issues the
seismicity of the of the job and the
proximity to LAX and those two kind of
problems became a driving force and how
the building ultimately looks the way it
does we worked with HKS from the very
early stages of design being here in LA
and it's obviously very high seismic
zone we've got a fault running right
behind the stadium but that also coupled
with the site you might see some
airplanes behind me flying over the
stadium we're really close to LAX and we
had to be below an elevation for the FAA
to let these planes come by on this site
that meant we had to push the stadium
about a hundred feet into the ground
which is extremely unusual to do that
right next to a fault was a challenge on
a scale that no one has ever tackled
before so the seismic demands quite
large we had to plan for that from the
start we're designing for a major event
either on the San Andreas Fault or
Newport Inglewood fault that runs right
past the stadium the roof structure sits
on columns that that have Isolators so
that essentially the ground can move
underneath the roof structure and not
impart large accelerations in a major
seismic event we expect that isolator to
move about 50 inches it's important to
note that the the roof structure and the
seating bowl structure are completely
independent they don't touch the Newport
Englewood fault is just that way a
little bit and it runs kind of
north-south so in the event of an
earthquake the motion is going to be
stronger if
if the earthquake happens on that fall
it's gonna be stronger east-west so this
way right here back and forth this can
be stronger than this way and the
Isolators will tend to move a little bit
more in that direction as there's more
energy from the fault moving back and
forth this way
I think what's it amazing about the
design team that we've brought no one
ever said no I don't think this is
possible
everyone kind of tackled was like okay
this is a challenge how are we gonna do
it this is a unique architectural wonder
of the world and recently the final
piece of the canopy show was lifted and
set in place forming the outline for the
iconic roof that will be seen by tens of
millions of people annually as they fly
into LAX sofa stadiums very unique with
this roof canopy system that they have
it's not like your typical structure
that's enclosed the idea behind sofa
stadium is for the comfort of the fans
to be one-click better than sitting in
an outdoor stadium so you're still
getting all of the outdoor breeze on all
four sides of the stadium but you're
shaded by the fretted pattern et fe
panels above you a lot of people ask us
why do we have a roof in a stadium why
are we covering for us it became a
guarantee you know these buildings now
aren't just for football all right they
have to be entertainment destinations
and so the roof for us was a guarantee
it all starts out at a high level and
then starts to just you know get deeper
and deeper into the details the metal
panel on the on the CEO is a fascinating
kind of exploration for us and and what
we're seeing here is a series of
mock-ups that we utilize testing
different geometries of perforation
different sizes and scales of holes and
ultimately a full-scale sized mock-up of
what an actual panel would be at the
stadium and we did this to make sure
that we are getting the correct amount
of light transparency
the airflow this stadium is going to
appear as a solid object from a distance
and we knew we wanted to change that
perception as you get closer and closer
to the building so as you get from say
the macroscale the air until you
transition to the site you start to
notice that you know can I see through
this building you know can I am I
looking at them through the bowl the
metal which if you can kind of see here
there's actually the first time that
it's been utilized it's called white
anodization or the group out at Kansas
City zainer metals to create this this
this metal it's a beautiful thing that
looks almost white in direct sunlight
but transitions throughout the day so
sunsets sunrises it's going to capture
the the pinks and the oranges the hues
of the beautiful sunsets here so it's
gonna change and evolve throughout the
day and then at night it transitions and
transforms so that holes which we're
letting light into the building actually
in a reverse at night and they emit
light so we have a series of color
changing LEDs throughout the the canopy
of this building that really allow lit
pulse with the energy of the events that
are happening in my career I've been to
several stadiums worked on several
stadiums and the scale of sofa Stadium
really is you know beyond what I've seen
before how do we create the ultimate fan
experience I hope when people would go
to the stadium for the first time yet
they feel like that this building
couldn't happen anywhere else in the
world
