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 incorpora tion
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:
Piezometer and Inclinometer
Casing Installation Lock & Dam No. 25
Location: Winfield, Missouri
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. Field work 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.

Motor Transport Operators
Course DACA41-92-C-0030
Location: Fort Leonard Wood, Missouri
Owner:
United States ArmyPROJECT DESCRIPTION
Palmerton
& Parrish, Inc. provided services to Willard Quarries, Inc. for
purposes of evaluating the aggregates to be used for graded
aggregate base, compacted aggregate base and for both intermediate
and surface asphalt aggregate. This material will be used in the
construction of parking lots and roadway pavements for the Motor
Transport Operators Course Construction at Fort Leonard Wood,
Missouri. Construction activities included the placement of
approximately 80,000 tons of aggregate base material and 80,000 tons
of bituminous asphalt pavement.
Laboratory
testing was accomplished to evaluate the magnesium sulfate soundness
and L.A. Abrasion characteristics of the proposed quarry
aggregate. Stockpile gradations and determinations of specific
gravities and absorption values were performed during crushing.
Mix designs
for both intermediate and surface mixes were prepared by Palmerton
& Parrish and the firms providing project testing and control
during laydown.
During the
progress of the work, Palmerton & Parrish, Inc. personnel have
worked closely with Kansas City Corp of Engineer personnel, the
Resident Engineer and staff at Fort Leonard Wood and with
representatives of the Asphalt Institute.

Power Generation Peaking
Turbines
Location: Essex and Maryville, Missouri
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 Boothill 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 Boothill. 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 proce dures.
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.

Public Affairs Building
Location: Springfield, Missouri
Owner:
Southwest Missouri State University
Date:
1997
PROJECT DESCRIPTION
Palmerton
& Parrish, Inc. provided Geotechnical Services required for this
five-story with basement educational facility. The investigation
required sampling and analysis of both foundation soils and the
shallow bedrock unit for evaluation for both shallow and deep
foundation units supporting both basement and non-basement areas.
Rock coring of the local Burlington Formation which is a karst
limestone was performed to determine suitability of the bedrock for
support of drilled piers. A drilled pier foundation system at high
end bearing pressure socketed into the competent limestone was
selected for support of this major educational structure.
Following the
Geotechnical Investigation, Palmerton & Parrish, Inc. provided
design services for the subsurface drainage system for the basement
and connecting tunnel and assisted in determination of appropriate
lateral earth pressures for basement and tunnel design. The
subsurface drain system incorporated a geomembrane for waterproofing
and geosynthetic for subsurface drainage to buried piping. The
underdrain system was designed in close cooperation with the
Structural and Mechanical Engineers to be compatible with the
structural and mechanical systems.
Palmerton
& Parrish was engaged as the project Geotechnical Engineer in
fielding inquiries from general contractors, piering contractors and
excavating contractors bidding the project.
