INSTRUCTOR:  Jerry A. DiMaggio P.E., D.GE, M.ASCE  

The instructor is very knowledgeable and has lots of experience. Excellent presentation.

This webinar offering concentrates on the design and construction of driven-pile foundations. Driven pile foundations are often a technically sound and cost-effective foundation choice where a deep foundation solution is appropriate based on site conditions, applied loads and project schedule and performance requirements. The LRFD platform offers a rational framework for consideration of driven pile foundation systems. The webinar will use the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge Design Specifications as a basis for the technical content. Applicable articles in Section 10.5 and 10.7 of AASHTO LRFD Specifications will be used as a basis of discussion.

The webinar will include discussion on the choice of driven pile type, definition of appropriate limit states under strength, service and extreme limit state conditions in a rational and sequential approach. Both structural and geotechnical limit state checks will be examined as well as special design situations, such as scour, time changes to geotechnical resistance and seismic conditions. Special attention is focused on appropriate use of static analysis methods, the importance of driveability analysis and the selection of construction monitoring tools. Brief discussion on consideration of scour, setup and relaxation will also be included. The webinar will assume that the participant has a basic working knowledge of the driven pile design and construction on soil and rock.

Learning Outcomes

This webinar will help you design and establish construction monitoring programs for driven pile foundations on soil and rock using the LRFD approach.

Webinar Benefits

• Learn the basics of the LRFD platform as applied to driven pile design and construction
• Continue building on the knowledge gained from previous LRFD webinars
• Examine the possibilities and benefits of improved communications between geotechnical, structural and construction specialists for driven pile design and construction

Intended Audience

This webinar will benefit geotechnical, structural and construction specialists, as well as general civil engineering professionals involved in the design and construction of driven pile foundations. Driven pile contractors and material suppliers will also find the webinar very valuable. Basic knowledge of LRFD and geotechnical principles is a prerequisite. The webinar will benefit professionals, and construction specialists with 0-25 years of practical experience in driven pile foundations use.
