This webinar was co-sponsored by ASCE's Structural Engineering Institute (SEI) and ASCE Continuing Education
Instructor: James A. D'Aloisio, P.E., SECB, LEED AP
Course Length: 1 Hour
Purpose and Background
A frost-protected shallow foundation system (FPSF) is an alternative to extending footings below the frost line to avoid foundation frost heave. The design methodology uses insulation and proper backfill selection to prevent the soils below the foundations from freezing. These can be set at a much shallower depth than conventional foundations. Use of FPSF can reduce a project's required excavation depth and allow reduced use of concrete, which saves construction time and money, in addition to other benefits. This webinar presents an overview of the concept, summarizes the benefits and potential challenges for design and construction, considers integration with insulation requirements for energy code compliance, and reviews the design methodology for heated and unheated buildings and other structures.
Primary Discussion Topics
- Frost depth vs. depth of frost-protected foundations
- Comparisons of material and impact quantities for FPSF vs regular foundations
- Drainage requirements for FPSF systems
- Integration with energy code insulation requirements
- Pitfalls to avoid when using FPSF

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]
