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.
