Transportation

PPI serves a cross section of Clients in the Transportation sector, including the Missouri Department of Transportation (MoDOT); Kansas Department of Transportation (KDOT); Oklahoma Department of Transportation (ODOT); Arkansas State Highway and Transportation Department (AHTD); numerous municipalities including city and county governments; multiple consultants specializing in bridge, roadway, railroad, and airport design; and numerous contractors responsible for construction of transportation infrastructure.  Of particular note are PPI’s:

  • Prequalified Consultant Status with MoDOT;
  • On-Call Geotechnical Services Contract with KDOT (2008 to 2012; 2012 to Current);
  • On Demand Geotechnical Services Contract with ODOT (EC 1444, 2013 to 2015);
  • Long-standing role as Geotechnical Engineer of Record and Construction Materials Testing Firm for the Springfield-Branson National Airport;
  • Geotechnical Engineer of Record for hundreds of city and county bridges;
  • Subsurface Drilling Contractor for hundreds of MoDOT, KDOT, ODOT, and AHTD bridge projects, completing investigative core holes and concrete coring for drilled pier foundations; and
  • Subsurface Drilling Contractor for dozens of new BNSF bridges and bridge replacements.

Representative transportation-related Projects include the MoDOT Safe and Sound Bridge Program in 2009 and 2010, during which PPI completed subsurface investigations for over 120 bridges in a 6 month period.  In 2014 and 2015, PPI was the Geotechnical Engineer of Record on the Ozark Regional Road Constructors (ORRC) Design-Build Team for the Rogersville U.S. 60 Project Freeway in Greene and Webster Counties.  Subsurface investigation for the Project included geophysical and traditional subsurface drilling studies to gather data for design of new bridge foundations, sinkhole avoidance and mitigation, and new abutment fills.  PPI also provided Construction Materials Testing (CMT) services for the Contractor’s Quality Control (QC) Program during construction.

PPI was the Geotechnical Engineer of Record for the City of Joplin’s TIGER Grant Project, 20th Street Overpass at the KCS Railway.  PPI mobilized four (4) drill rigs in December 2012 and January 2013 to allow efficient completion of the field subsurface investigation and accelerated completion of the Geotechnical Engineering Report.  Supplemental studies were completed to investigate possible mine features within the project extents, and PPI provided CMT services under contract to the Design Engineer, Transystems, in 2015.
