I-15 Reconstruction Project. Salt Lake
City, Utah. Dynamic Pile Testing,
PDA.
The I-15 reconstruction project was one of the largest highway construction projects ever
performed in Utah covering about 15 miles of the interstate going though Salt Lake City, Utah.
The project involved reconstructing the entire freeway during ongoing traffic. Wasatch
Constructors, the general contractor and our client, drove more than 18,000 steel pipe piles
for 150 new bridges over a period of 4 years starting 1997. PDA Engineering performed all the
dynamic pile testing, PDA, for this project. |

Legacy Parkway Project, Davis County,
Utah. Dynamic Pile Testing,
PDA. The Legacy
Project
involves
constructing a
completely new
highway, part
of which
crosses through
some protected
wetlands of the
Great Salt
Lake. The new
highway, which
has about 60
bridges founded
on pipe piles
along its
alignment, was
started a
couple of years
ago but was
shut down
halfway through
the project due
to
environmental
protests.
PDA performed
all the dynamic
pile testing,
PDA, and pile
inspection
services for S&ME
on this project
before it was
shut down. The
project is
expected to
continue in the
near
future.

Sutter Power Plant, Yuba City, CA. Static
Load Testing of Piles.
This project consisted constructing a new alternate fuel power plant founded on 16”
square concrete piles. The project was managed by Bechtel who used Foundation Constructors out
of Oakley, CA to drive the piles. PDA Engineering performed static load testing on 4 different
piles in compression, tension and lateral loading. |

123rd South Reconstruction Project,
Draper, Utah. Dynamic Testing,
PDA. GRW, a joint
venture of
three large
construction
companies in
Salt Lake City,
Utah, took on
this relatively
large design
build project
for Utah
Department of
Transportation.
The project
involved
rebuilding
several miles
of the 12300
South Street
including a
massive SPUI
overpass bridge
over I-15, a
rail road
bridge and a
bridge over the
Jordan River.
All the bridges
were founded on
pipe piles,
which PDA
Engineering
tested with the
PDA.

Walmart Super Center, Salt Lake City,
Utah. Dynamic and Static Load
Testing. PDA
Engineering
performed
extensive
dynamic
testing of
driven
steel pipe
piles on
this
project,
which
consisted
of driving
over 800
pipe piles
for a two
story
parking
garage. Two
static load
tests were
performed
initially
on the
project for
correlating
with the
PDA testing
used during
the
production
pile
driving.

Carbon County Jail, Rawlins, Wyoming.
Dynamic Pile Testing, PDA.
For this project over 400, 12 inch square concrete piles had to be driven through loose fill
and into dense sands. PDA Engineering performed a dynamic pile test program prior to
production pile driving in order to determine pile lengths before casting the piles.

Four Bears Bridge ND23, North Dakota.
Dynamic Pile Testing, PDA.
The existing bridge leading ND State Route 24 over Lake Sakaneva is currently being replaced
by a new 16 pier bridge founded on 36 inch diameter pipe piles. The contractor Fru-Con hired
PDA Engineering to perform dynamic Pile testing, PDA during the indicator pile test program
before the production pile driving began. Pile testing was performed at each pier on indicator
piles driven from a pontoon barge. |

The Pointe @ 5300 South, Murray, UT
– Permanent Shotcrete Retating
Wall. This project
involved
designing a 22
ft tall
permanent
shotcrete
retaining wall
using two
different
methods. The
wall was
divided into
two parts, one
which was
constructed
using soil
nails and
shotcrete, and
the other
using tied
back sheet
piles covered
with shotcrete
facing. Both
parts of the
wall were
integrated.
The latter
method was
used to speed
up the
construction
process.

North Davis Sewage Treatment Plant,
Syracuse, Utah. Sheet Pile Cofferdam
Design. PDA designed
two very
large deep
sheet pile
cofferdams
for this
project
using a
unique waler
system. The
soils at
this
location are
very soft
with high
groundwater
table making
the design
and
construction
of these
25-30 ft
deep
cofferdams
very
challenging.

Decker North Sewer Lift Station. West
Valley, Utah. Sheet Pile Cofferdam
Design. A 40 ft deep
sheet pile
cofferdam
was designed
for this
project
using a
standard
waling
system in
soft soils
with high
groundwater
table. The
close
proximity of
existing
structures
sensitive to
settlement
required
special
shoring
design and
dewatering
techniques.
Two more
closely
identical
cofferdams
were later
designed for
the same
client in
nearby
locations.

Olmsted Flowline Replacement Project.
Provo Canyon, Utah. Soil Nail
Inspections. The
replacement
of an
existing
10 ft
diameter
water
pipe
placed
up on a
steep
slope
of
Provo
Canyon
required
extensive
soil
nailing
spanning
over 2
years.
PDA
Engineering
performed
all
soil
nail
pull
out
testing,
inspections
and
documentations
during
the
installation
period.

Roosevelt Gap Resort. Deer Valley, Utah.
Soil Nail Wall Design and
Inspections.
Roosevelt Gap Resort is nestled into the ski slopes of Deer Valley ski resort with ski-in and
ski-out access. The hotel is cut deep into the steep slopes of a large hillside. The cuts required
for the construction of the hotel are up to 70 ft tall in places and protected by soil nails and
permanent shotcrete facing. The project was started 3 years ago but construction was halted halfway
through the soil nailing due to financing problems. At this point the project has not continued but
is expected to do so in the near future. PDA Engineering performed soil nail shoring design of some
of these walls including soil nail pull out testing and inspections. |
