Jet Grouting: Pier 3 of Bill Emerson Memorial Bridge

Cape Girardeau, MO.
 
August 1997 to February 2000
 
The foundation limestone for the seismically critical Pier 3 of this massive new road bridge over the Mississippi River was found to contain huge karstic features, infilled with red clay. Various deep foundation options to support the pier’s footing were examined but found to be not cost effective and practically impossible technically.

Geosystems acted as a subconsultant to the bridge designer (HNTB of Kansas City, MO) to review possible foundation remediation options, and 3-fluid jet grouting of the 129 foot by 87.5 foot foundation for a depth of 50 feet below rock head was recommended.

Geosystems range of services on this project included:

  • Initial technical assessment of conditions.
  • Assistance in drafting of specifications and preliminary designs.
  • Monitoring and recording of all field test programs and subsequent production work.
  • Conducting material QA/QC programs.
  • Coordinating verification methodologies.
  • Maintenance of daily records.
  • Preparation of interim and final technical reports.
  • By the end of construction, the foundation had been treated to a level satisfactory to resist the designer’s calculated loading requirements.
