Project:
Branson Medical Mall,
Parking Garage and Cahill Road Extension
Location: Branson, MO
Owner:
Skaggs Community
Hospital
Date:
1998 to 2000
PROJECT DESCRIPTION
Palmerton & Parrish, Inc. was
retained to provide Geotechnical Services for this multi-million
dollar hospital expansion and road extension project. Project
includes construction of a three story pre-cast parking garage
structure, five story steel frame Medical Mall building and
extension of Cahill Road. During the Geotechnical Investigation,
use of an ATV drill was required due to steeply sloping wooded
terrain. A Geotechnical Investigation was performed which required
soil sampling and rock coring for both shallow and deep
foundations and for slope stability analysis. Geotechnical aspects
of the project included recommendations for both shallow spread
footings and drilled piers upon dolomite bedrock, fill placement
upon steeply sloping natural hill slope and incorporation of grid
reinforcement into fill slopes to increase degree of slope and
allow structure support upon the crest of slope.
The Cahill Road
Extension required placement of a deep rock fill over localized
alluvial deposits. Palmerton & Parrish performed slope stability
analyses and recommended staged construction to allow dissipation of
pore pressures in natural alluvial deposits below the fill mass. To
verify dissipation of pore pressures, Palmerton & Parrish installed
pneumatic piezometers. Palmerton & Parrish field personnel were
required to monitor piezometer levels to coordinate staged
construction.
Palmerton & Parrish was engaged
to provide construction testing and inspection during the
construction phase of the project. Palmerton & Parrish inspected
installation of spread footings and drilled piers to bedrock,
installation of Tensar Reinforcing Grid in fill slopes as well as
testing of cast-in-place concrete and compacted earth fills. During
building erection, Palmerton & Parrish provided fireproof testing
and inspection and testing of structural connections. Fillet welds
required visual inspection and magnetic particle testing. Moment
connection and field splice welds required ultrasonic testing by an
ASNT Level II Inspector.

Project:
Springfield/Branson National Airport
Location:
Springfield, MO
Owner:
City of Springfield
Date:
March 2006 to April 2009
PROJECT
DESCRIPTION
The Springfield/Branson National
Airport is currently constructing a new Midfield Terminal facility.
The estimated design and construction cost for the entire project is
about $105,000,000. Approximately $80,000,000 of that cost is
associated with site preparation, the foundation package, and
terminal construction, and $25,000,000 is associated with
construction of the aprons, taxiways, landside parking lots, and
entrance roads. Palmerton & Parrish has been involved with the
project as the Geotechnical Engineer and the Quality Assurance
Testing Agency.
Palmerton & Parrish performed
multiple geotechnical investigations as the Geotechnical Engineer
for the project. The geotechnical investigations included drilling
of numerous subsurface borings through soil and rock materials,
collection of subsurface samples, laboratory testing of collected
samples, and preparation of geotechnical engineering reports with
recommendations pertinent to geotechnical engineering design and
site development. Geotechnical engineering recommendations included
recommendations for subgrade stabilization, soil compaction
criteria, concrete and asphalt pavement construction, and detailed
recommendations for drilled pier design and construction for the
Terminal Building.
As the Quality Assurance Testing
Agency, Palmerton & Parrish provided full-time materials testing and
construction observation by a senior level field technician during
completion of the $14,000,000 site grading contract, which lasted
approximately 12 months. Services provided during completion of the
site grading contract included observation of soil subgrades,
including removal and replacement as required, and field density
testing of soil fill compaction. Due to the magnitude of the
project, accurate record keeping and correspondence of field density
test results was a critical part of our services. Palmerton &
Parrish’s services have included pre-drilling of drilled pier
foundation, full-time observation during drilled pier construction
including inspection of concrete reinforcement placement and
concrete sampling and testing, concrete sampling and testing for the
Terminal Building structure, and compaction testing of modular wall
backfill.

Project:
Piezometer and Inclinometer
Casing Installation Lock & Dam No. 25
 Location:
Winfield, MO
Owner:
U.S. Corp of Engineers - St.
Louis District
Date:
1995
PROJECT DESCRIPTION
Lock and Dam No. 25 is a Corp of
Engineers Facility near Winfield, Missouri with an operating lock
near the Missouri shore and Dam across the Mississippi River. The
facility is vital to barge and pleasure boat traffic traveling the
waterway. The Corp of Engineers required installation of
inclinometer casing at three locations through the Lock Wall
socketed approximately 5 feet into bedrock and one piezometer
through the Lock Wall. Sampling of alluvium deposits and Standard
Penetration Tests (SPTs) were also required at 5-foot intervals. The
east Lock Wall is nearly 100 feet from the Missouri Shore and
inaccessible to equipment from land. The project also required
installation of eight Piezometers through the dam structure 5 feet
below the base of concrete and sampling of alluvium deposits to
bedrock.
A major challenge of this
project was difficult access conditions. Equipment could only be
mobilized to drilling locations through hoisting with a crane
mounted on a barge platform. Although the drilling depths and hole
sizes dictated use of a large size auger drill and mud pump,
drilling equipment was limited to smaller weights which could be
crane hoisted. For inclinometer installation, a 6-inch diameter bore
hole was required through the initial 40 feet of reinforced concrete
of the lock wall. For piezometer installation, a 3.75-inch diameter
bore hole was required through the 40 feet of lock wall and dam
concrete. A 6-inch diameter bore hole was also required through deep
alluvium deposits to bedrock at a depth of approximately 120 feet
and 5 feet into bedrock. Retrieval of rock core from the bedrock
unit was also required at many piezometer and inclinometer
locations. Fieldwork required close cooperation between Palmerton &
Parrish field personnel and Corp of Engineers operating the lock
facility since the lock was in operation throughout the project.

Location:
Essex and Maryville, MO
Owner:
Associated Electric
Cooperative
Date:
Fall of 1998
PROJECT DESCRIPTION
Palmerton & Parrish, Inc. was
engaged to perform a Geotechnical Investigation at both sites. One
in the Missouri Bootheel and the other in Northwest Missouri for
these power generation units with heavy compressive loads and
significant machine vibrations. Drilling depths ranging from 65 to
85 feet were required within the thick glacial deposits of
northern Missouri and deep sand alluvium of the Missouri Bootheel.
At the Essex site, downhole shear
wave testing was also required. Drilling procedures required
shelby tube sampling through hollow stem augers as well as
performance of Standard Penetration Tests (SPT) in deep sands
below the water table while using wash boring procedures. A
geologist was also provided to log the borings, collect soil
specimens and observe drilling procedures.
A geotechnical report was prepared submitting boring logs and
alternate recommendations for foundation support. At the Essex
site, a pile load test was witnessed to confirm load bearing of
the selected pile type. Installation of auger cast piles was
inspected by a representative of Palmerton & Parrish during
construction.
