the
undertaking.
Next
slide.
Please
the
stone
arch
bridge,
which
is
also
known
as
bridge

27004,
is
located
within
the
saint
anthony
falls
local
historic
district,
as
well
as
the
national
register
historic
district,
and
it
is
also
a
national
historic
civil
engineering
landmark
it's
completed
in
1883
and
the
bridge
is
a
former
road
bridge
crossing
the
mississippi
river
in
downtown
minneapolis.
G
G

I
will
keep
my
part
of
this
presentation
very
brief.
Therefore.
This
concludes
my
part
of
the
presentation
I'm
available
for
any
questions,
but
the
applicant
is
here
and
will
be
giving
a
more
detailed
presentation
on
the
scope
of
work.
E
A
Thank
you,
hello.
My
name
is
katie
hanskering.
I
am
a
historian
with
the
mndot
cultural
resources
unit
and
the
project
manager
from
the
historian
perspective
for
the
stone
arch
bridge,
our
historical
consultant,
todd
grover
with
mcdonald
mac.
Architects
will
walk
us
through
the
presentation
and
he
and
I
can
be
available
for
any
specific
questions
from
the
hpc.
F
Thank
you,
katie
hello,
I'm
todd
grover
from
mcdonald's,
mac,
architects
and
we've
been
working
with
mndot
on
this
project.
We
are
a
consultant
with
mndot,
but
there
is
a
bridge
engineer
that
has
been
working
on
the
project
lhb
and
they
are
the
engineering
firm
of
record
for
the
repairs,
and
so
we've
been
working
with
them
throughout
this
process
to
from
the
assessment
and
analysis
of
the
of
the
bridge
through
the
development
of
of
documents
for
the
repairs
of
the
bridge.
F
F
So,
just
as
as
staff
had
mentioned
that
this
is
we
recognize,
this
is
a
important
landmark
to
our
region.
The
rehabilitation
of
this
project
will
really
focus
on
repairing
and
maintaining
the
integrity
of
the
stonework
on
the
bridge.
There's
going
to
be
a
full
repointing,
there's
going
to
be
repairs
to
some
stone,
cracking
there's
going
to
be
replacements,
of
some
severely
deteriorated,
stone
and
I'll.
F
Show
you
some
images
of
that
in
a
second
repairing
of
the
drain,
weeps
that
are
currently
on
the
building,
the
repairing
of
metal
tie
rods.
I'll
show
you
some
images
of
that
and
talk
about
that
in
a
moment,
and
then
repairing
installing
scour
and
break
water
protection
at
the
base
of
the
piers.
As
as
has
been
mentioned,
all
work
will
follow
secretary
of
interior
standards
for
the
treatment
of
historic
properties.
F
F
F
This
really
started
out
with
a
very,
very
intensive
assessment
of
the
bridge
to
develop
the
the
scope
of
the
work
that
needs
to
happen.
This
assessment
started
out
with
an
initial
assessment
a
number
of
years
ago,
but
really
went
deep
into
looking,
almost
at
every
stone
and
every
mortar
joint
on
the
bridge
last
year.
F
F
There
was
underwater
both
scanning
and
scuba
investigation
done
at
the
piers
that
were
underneath
the
wall
under
the
water
during
the
water
drawdown
last
last
year.
There
was
a
validation
of
the
underwater,
the
underwater
conditions
investigation
that
some
of
the
piers
that
were
now
in
dry
conditions
rather
than
being
underwater
and
the
understanding
of
the
riverbed
around
the
around
the
piers
granted.
Not
everything
was
understood
during
that
drawdown
because
there
was
still
water
some
water
flowing
through,
but
we
got
a
the
bridge.
Engineers
got
a
much
better
understanding
of
the
scope
of
work.
F
Part
of
the
identification
of
the
issues
were
identifying
the
different
stone
types
looking
at
the
motor
conditions,
stone,
cracking
and
deterioration
both
from
a
visual
but
also
a
condition
analysis
and
then
also
looking
at
some
of
the
previous
repairs
that
have
been
done
on
the
bridge.
Just
a
brief.
His
brief
overview,
the
you
know,
from
the
original
construction
of
the
bridge
there
had
been
some
subsequent
repairs
done,
some
repairs
done
in
the
early
1910s,
where
there
was
some
reinforcing
put
into
the
bridge.
F
These
tie
rods
that
go
through
the
bridge,
along
with
some
infilling
of
the
bridge,
with
some
some
concrete
because
of
some
deterioration.
That
happened,
but
then
we
also
have
in
the
1960s
some
some
repairs
that
were
made
to
a
few
of
the
arch
spans
that
were
seeing
some
settlement
and
some
shifting,
but
also
the
significant
repairs
that
had
happened
once
the
once
the
corps
of
engineers
lock
and
dam
were
installed.
F
F
We
also
perform
the
there's
a
number
of
testing
procedures
that
were
also
performed
on
the
bridge.
What
these
were
really
trying
to
do
was
identifying
the
stone
and
mortar
conditions,
especially
where
we
had
a
number
of
areas
where
there
was
stone
delaminating,
we
wrote
what
what
we
did
is
the
there
was
a
number
of
hammer
testing
areas
that
were
done
to
try
to
understand
the
the
condition
of
the
stones
and
then
once
we
were
identified
able
to
identify
some
of
those
stones.
F
The
intention
with
the
full
repointing
of
the
bridge
is
to
try
to
achieve
a
mortar.
That
is
in
as
aesthetics
comparable
to
the
historic
mortar,
but
also
have
a
mortar
that
is,
is
going
to
be
a
durable
mortar
on
the
bridge
just
because
there
this
is
obviously
a
bridge
that
sees
some
extreme
exposure.
Go
ahead
next
slide.
F
So
the
the
bridge
repairs
that
are
that
we're
going
to
be
undertaking
are
listed
on
the
left
hand,
side,
water,
repointing,
the
entire
bridge
needs
to
be
repointed.
All
of
the
existing
mortar
joints
are
in
in
poor
to
failing
condition,
but
we
also
have
some
issues
with
stone,
cracking
and
edge
loss.
This
is
a
good
image
showing
both
of
those
conditions,
the
stone
most
to
the
right.
F
But
if
you
do
notice
the
stone
kind
of
to
the
center
of
a
darker
stone
towards
the
top
of
the
image.
You
can
see
that
a
lot
of
these
stones
have
some
edge
loss
on
the
stone,
and
we
know
that
during
the
repointing
process,
when
that
mortar
is
removed,
some
of
that
edge
stone
will
be
lost
instead
of
replacing
that
giant
stone.
That's
there.
F
There
are
going
to
be
some
stones
that
we're
going
to
be
have
to
reface
you'll,
see
a
picture
of
that
later
on,
where
they
just
are
too
deteriorated.
That's
what
some
of
the
the
testing
helped
us
to
determine
was
how
deep
this
deterioration
occurs
within
the
stone,
but
then
developing
a
process
that
we
can
essentially
take
the
the
front
six
to
eight
inches
off
of
that
stone
and
install
a
new
veneer
stone
on.
F
On
top
of
that
stone,
the
intention
is
to
drill
some
supports
back
into
that
stone
or
drill
some
acres
into
that
stone,
and
then,
through
that
process,
essentially
mechanically
anchor
that
stone
back
to
the
solid
stone
behind
within
that
process,
it
will
require
some
more
some
stone
plugs
to
be
put
into
the
face
of
of
the
stone,
but
that
process
will
work
as
we
have
developed.
The
process
of
selecting
stone
and
you'll
see
an
image
of
that
in
a
second.
F
The
the
intention
is
that
the
stone
plugs
that
will
be
put
in
there
will
be
minimally
visible,
if
not
really
kind
of
be
hidden
within
the
massiveness
of
the
stone
once
those
anchors
are
put
in.
We
do
have
some
tie.
Rod,
repairs
I'll,
show
you
an
image
of
that
in
a
second
some
scour
protection
on
a
couple
of
the
piers
that
are
in
the
main
channel
of
the
river
and
some
graffiti
removal.
I
want
to
go
to
the
next
slide.
F
F
There
are
some
that
are
still
providing
some
structural
support
that
are
damaged,
and
so
those
we're
going
to
be
doing
a
repair
where
we're
going
to
be
going
back
into
the
tie,
rod
and
re-anchoring
those
to
the
face
of
the
bridge
most
of
those
locations
are
on
mortar
joints.
As
you
can
see
here,
there
are
going
to
be
a
couple
of
locations
where
there's
going
to
be
some
stone
refacing
that
has
to
be
done
around
the
tie.
F
F
So
what
we're
going
to
be
doing
is
extending
those
essentially
putting
a
cap
over
those
and
extending
those
away
from
the
bridge
to
make
sure
that
any
water
that
does
come
out
of
those
exits
further
away
from
the
face
of
the
bridge
in
a
lot
of
these
locations.
The
stone
underneath
these
drain
holes
are
are
more
deteriorated
than
other
areas,
and
so
we
want
to
try
to
get
as
much
of
that
water
away
as
possible,
and
then
there
are
two
piers
in
in
the
in
the
channel
that
have
this
nose
on
the
pier
one.
F
F
Here's
a
good
picture
of
that
failed
stone
edge
where
there
is
the
stone
below
it
is
in
good
condition
and
want.
We
would
want
to
retain
as
much
of
that
stone
as
possible,
but
that,
as
that
reporting
process
happens,
some
of
that
stone
edge
is
going
to
be
lost,
so
we're
going
to
get
a
widened
joint
in
that
location
and
then
also
some
of
the
graffiti
removal.
That's
going
to
be
happening
on
the
bridge.
A
couple
examples
of
that.
F
F
This
is
a
good
picture
of
the
a
deteriorated
stone.
That's
going
to
be
replaced,
you
can
see
the
significant
cracking.
That's
happened
with
the
stone
again.
This
is
one
that
will
a
new
stone
face.
We
put
on
the
stone
and
be
anchored
back
into
the
the
stable
stone.
That's
deeper
within
within
the
the
structure
of
the
bridge.
Again,
six
to
eight
inches
or
more
is:
is
the
depth
that's
going
to
be
removed
and
then
anchored
anchored
to
to
the
stone
behind
it.
F
We're
also
on
a
couple
of
the
piers
that
had
some
concrete
repairs
already
to
to
the
base
of
the
piers.
This
is
this
concrete's
going
to
be
repaired,
it's
been
deteriorated
and
so
those
concrete,
pier
bases
will
be
repaired,
and
so
the
deterioration
is
corrected
and
are
more
stable.
Peer
base
next
slide.
Please.
F
Qualities
the
stone
itself,
stone,
density
and
stone
strength,
and
so
here's
just
an
example
of
two
of
the
four
stone
types
on
the
bridge
that
we
were
able
to
find
very
good
matches
for
and
and
these
a
lot
of
these
stones
are
actually
from
or
the
these
stones
that
we've
sampled
from
are
actually
from
the
historic
quarries
that
we've
been
able
to
document
that
were
originally
used
to
to
build
the
bridge
next
slide.
Please.
F
So
the
schedule
for
this
is
right.
Now
we
are
in
the
final
production
stage.
Our
lhp
is
in
the
final
production
stage
for
their
documents
during
the
summer
of
2022,
there's
going
to
be
the
project
bidding
and
contractor
selection,
with
the
hope
that,
in
the
fall
of
2022
that
we
can
start
up
some
of
the
initial
mock-up
there's
going
to
be
a
significant
mock-up
process,
both
for
stone
selection,
stone,
shaping,
mortar
installation,
mortar
removals.
F
This
whole
series
of
processes
with
the
historic
masonry
and
we're
hoping
that
some
of
those
can
start
in
the
fall
of
2022
so
that
when
spring
of
2023
we
can
start
it
start
in
on
the
project.
The
project
is
going
to
be
over
two
years,
with
one
half
the
bridge
being
done
during
one
construction
season
and
then
extending
into
2024
for
the
second
half
of
the
bridge,
and
with
that
I
am
happy
to
have
amber
or
katie
fill
in
anything.
I
may
have
missed
or
opened
any
questions.
E
Thank
you
for
your
presentation,
todd
and
katie.
We
appreciate
your
time
and
being
here.
Commissioners,
let's
discuss
any
comments
or
questions.
You
may
have
please
kind
of
raise
your
hand
or
shoot
a
message.
In
the
meantime,
I
do
have
a
couple
of
questions,
todd
and
katie.
I
saw
in
some
of
the
early
photos
in
your
presentation
that
there
are
some
previous
repairs
that
were
made
that
appear
to
be
kind
of
like
a
concrete
block,
replacing
one
of
the
original
stones
and
just
wondering
how
those
are
going
to
be
treated.
F
Early
attempt
in
the
1960s
about
trying
to
repair
some
of
those
really
deteriorated
tracked
stones
and
instead,
instead
of
using
stone
as
a
veneer
replacement,
they
use
this
concrete
anchoring
kind
of
sight
poured
concrete
repair
to
to
to
repair
that
stone
they're
in
really
good
shape.
There's
really
nothing
wrong
with
them,
except
for
they're,
not
the
most
aesthetic,
and
so
the
determination
was
made
instead
of
doing
more
damage,
potentially
to
removing
those
because
they're
very
stable
and
they're
they're
concrete.
E
F
There's
not
a
lot
individual
stones,
I
mean
we
could
probably
go
in
and
count
them,
and
knowing
that
I
could
count
them
me.
You
know
kind
of
shows
that
they're
not
they're,
not
in
a
typical
condition
around
the
bridge,
they're
really
isolated.
Some
of
the
joints
are
isolated
more
towards
the
top
of
the
bridge
kind
of
where
the
walkway
was
put
where
the
old
rail
was
was
put
there.
F
E
F
E
F
A
They
have
not,
and
traditionally
in
the
past,
with
other
bridge
rehabilitation
projects,
they
are
usually
not
very
involved
when
it
comes
to
mock-up
reviews,
largely
because
they
trust
our
judgment
as
the
delegated
fhwa
agent.
And
you
know
if
there
are
particular
instances
where
we
feel
like
we
need
additional
consulting
party
feedback.
We
would
go
and
seek
it,
but
for
the
most
part,
mndot
cru
handles
the
mock-up
review
approval
process.
F
E
Yes,
obviously,
you
have
a
long
list
of
involved
parties,
so
I
appreciate
you
know
your
due
diligence
in
going
through
the
process.
I'm
sure
I'm
sure
there's
a
lot
of
agencies
looking
at
this
project.
Obviously
the
stone
arch
bridge
is
one
of
the
most
iconic
pieces
of
minneapolis,
so
I
do
appreciate
all
your
stewardship
and
and
the
work
that
you've
done
the
due
diligence
about
the
mortar
type
and
all
the
research.
E
H
You
I
don't
really
have
a
whole
lot
of
comments.
I
will
just
say
that
I
really
appreciate
the
stamps
that
you
guys
are
taking
towards
the
stone
and
it
sounds
like
you
are
being
really
careful
to
preserve
and
keep
what
you
can,
and
I
just
really
appreciate
the
sort
of
thorough
job
that
you
are
taking
there.
So
thank
you.
F
And
and-
and
I
would
say,
I'm
just
in
front
of
a
lot
of
people
who
have
done
a
lot
of
work
on
this,
and
I
would
say
that
lhb
has
done
a
significant
amount
of
work
in
being
very
careful
and
diligent,
knowing
knowing
the
the
how
iconic
and
and
important
this
bridge
is,
and
so
they've
been
leading
the
effort
and
and
being
very,
very
careful
in
all
of
their
recommendations.
And
it's
really
been
a
collaborative
effort
with
them
with
mndot
with
a
number
of
testing
agencies
and
engineers.
F
E
I'll
say
on
behalf
of
hbc:
thank
you
for
your
stewardship
and
your
due
diligence
in
this
project,
and
we
I
would
say
that
we
are
all
obviously
excited
to
see
the
ongoing
maintenance
and
that
the
bridge
gets
the
attention
it
deserves.
So
thank
you
and
I
believe,
unless
anybody
wants
to
comment,
I
think
that
wraps
up
our
comments,
unless
you
had
any
specific
questions
for
the
hvc
anything
specific
you
wanted
to
address.

Thank
you,
chair
sunburg.
I
don't
have
much.
I
just
wanted
to
say
that
we
have
found
one
hpc.
Commissioner,
that's
accepted
an
appointment
thus
far
to
come
on
to
the
hpc.
The
said,
commissioner,
I
won't
name
them
yet
still
needs
to
go
through
the
appointment
process
through
biz
and
council,
but
we
are
hoping
to
maybe
have
them
seated
by
middle
of
march.
