This webinar was co-sponsored by ASCE's Geo-Institute (G-I) and ASCE Continuing Education

Instructor:  Michael J. Byle, P.E., BC.GE., F.ASCE

Course Length: 90 minutes

Purpose and Background

It frequently becomes necessary to conduct investigations of existing foundations and structures due expansion, modernization, restoration and adjacent construction. For newer construction, plans may be available, but for older structures that is often not the case. Where there is limited or little information, investigations must be done to assess the nature and condition of structures for underpinning, condition assessment or reuse. This webinar presents strategies and tools useful in investigation of geo-structures such as foundations, retaining walls and other buried structures.

Proper planning of and execution of investigations is necessary for success. Proper planning and investigation require knowing construction methods and materials that may have been used in the original construction and assessment of configurations that might be expected. Understanding of available investigative tools is also essential. This webinar provides strategies and examples of geo-structural investigations for a variety of structures.

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
