TRB will conduct a webinar on Monday, June 24, 2019, from 2:00 PM to 4:00 PM ET that discusses the cone penetration test (CPT), which can provide data for investigating and characterizing site specific subsurface conditions. Improperly characterizing subsurface conditions may increase risks during the planning, design, construction, and operation of transportation infrastructure. This webinar will focus on using CPT to assess geoseismic hazards, such as liquefaction, using a case study of a highway bridge in California.

This webinar was organized by the TRB Standing Committee on Seismic Design and Performance of Bridges and the Standing Committee on Foundations of Bridges and Other Structures.

Some registrants will need to pay $95 to attend this webinar.  Sign into to view registration information.

Webinar Presenter

  • Sharid Amiri, Caltrans
  • Gerald Verbeek, Verbeek Management Services

Moderated by: Kenneth Fishman, McMahon & Mann Consulting Engineering and Geology

Webinar Outline

  1. Brief description of CPT technology
  2. Site investigation using CPT for a bridge site
  3. Site characteristics using CPT
  4. Seismic CPT data acquisition and analysis
  5. Evaluation of liquefaction at a given bridge site using CPT
  6. Question and answer session

The first 90 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions.

Learning Objectives

At the end of this webinar, participants will be able to:

  • Describe CPT technology and how to apply it to design highway bridges
  • Describe how to use CPT technology to investigate subsurface characterization on a highway bridge
  • Describe how to use CPT technology to evaluate liquefaction on a highway bridge

Professional Development Hour Information

A certificate for 2.0 Professional Development Hours (PDHs) will be provided to Professional Engineers (PEs) who register and attend the webinar as an individual For approved webinars, TRB’s webinar program awards Registered Continuing Education Provider (RCEP) Professional Development Hour (PDH) credits associated with participation only to the registered individual and not to other members of a group that view the webinar together. To receive PDH credits, please register as an individual and sign into the webinar from your personal computer. After doing this, you may join your group in a meeting room.  To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations.

In addition, advance registration is available until just before the webinar starts. Once the webinar starts, you will be unable to submit your registration. Individuals that are registered for a webinar but do not receive their confirmation emails due to their organization’s internal firewalls should contact the TRB Helpdesk ( for assistance in signing in.

Individuals registered as Florida PEs are no longer required to email TRB with your license number to report your attendance. Instead, please use your certificate that TRB provides through as verification of your attendance to the Florida Board of Professional Engineers.

Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.

This webinar was developed in March 2019. TRB has met the standards and requirements of the Registered Continuing Education Program (RCEP). Credit earned on completion of this program will be reported to RCEP by TRB. Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, DC 20005.
