Hi,
my
name
is
Eric
Balkan
and
I'm.
The
project
manager
for
the
school
district
here
at
Aloha
high
school.
The
issue
here
at
the
high
school
that
we're
trying
to
solve
is
that
the
building
itself
is
not
adequately
supported
in
case
of
a
seismic
event
or
an
earthquake
right
now.
The
roof
is
not
adequately
tied
to
the
walls.
The
walls
themselves
aren't
all
strong
enough
and
the
walls
also
aren't
tied
to
the
foundations
below.
So,
in
the
case
of
an
earthquake,
all
the
pieces
want
to
move
separately
and
potentially
topple
over.
A
So
the
way
we
tackled
our
problem
this
last
summer
was
that
we
started
by
digging
up
big
areas
of
the
concrete
slab
pouring
new
footings
full
of
rebar
and
concrete
in
the
ground.
Then
we
took
the
existing
walls
and
to
strengthen
them.
We
took
off
all
the
existing
drywall
put
up
new
plywood
sheeting
along
the
lengths
of
the
walls
and
then
tied
those
new
strengthened
walls
into
the
foundation,
creating
a
path
for
any
new
load
to
get
down
into
the
ground.
A
So
that
brings
us
to
next
summer,
at
which
point
we
will
upgrade
the
roof,
adding
new
plywood
to
the
roof
and
then
we're
strengthening
the
connections
between
our
new
upgraded
walls
to
the
roof.
So
we
will
add
new
blocking
along
the
top
of
these
walls,
tying
the
roof
into
the
walls
and
creating
a
single
path
for
any
loads
from
an
earthquake
to
get
from
the
roof
down
through
these
new
upgraded
walls
into
the
new
foundations
and
the
load
can
go
out
into
the
ground.
