Workshop:
Skill Level: Veteran; subject matter context is to be presented to an experienced preservation engineering audience
Denver soils are notorious for expansive clays and associated problems and challenges with the preservation and remediation of existing buildings. Soils issues will be presented and discussed by structural engineers and geotechnical engineers. Preservation issues associated with soils problems will be presented and discussed including their effects on existing structures, general diagnostics, investigative strategies to evaluate existing foundation systems, and Treatments.
Facilitators:

- Bill Jordan, PE, Bill Jordan & Associates, Newcastle, New South Wales, Australia
- Jerry E. Maly, PE, Wiss Janney Elstner, Inc., Denver, CO, USA

- Brian Renfrow, PE, Buckhorn Geotech, Montrose, CO, USA
- Fred Rutz, SE, J.R. Harris & Company, Denver, CO, USA
- Jim Shepherd, AIA, Beyer Blinder Belle, Washington, DC, USA
- Moncef Souissi, CTL|Thompson, Inc., Denver, CO, USA
- Justin M. Spivey, PE, Tipping Mar, Berkeley, CA, USA
- Dean Tills, PE, SE, Robert Silman Associates, New York, NY, USA
- Tom Szynakiewicz, Hayward Baker, Broomfield, CO, USA
Learning Objectives:
- Discuss various soils issues, characteristics and behaviors.
- Discuss diagnostic approaches and evaluations of building distress conditions that would indicate soils issues may exist.
- Identify the roles of the soils consultant and the preservation engineer when dealing with foundation/soils evaluations.
- List different solutions for various challenges when dealing with different soil types.
- Present physical examples and demonstrations of foundation restoration and soil strengthening approaches.
- List common soil typologies and mechanisms that trigger distress in historic structures.
- Link common observations of distressed conditions to potential soil or foundation issues.
- Describe the roles of the various professional design consultants and construction tradesmen in the evaluation, design and repair of structures with various foundation/soil issues.
- Develop a background of common soil/foundation repair solutions.
- Describe the construction practices and installation procedures of selected means of soil/foundation repair techniques through practical hands-on demonstrations.
Format:
The workshop format will include a mixture of lectures, discussion, case studies and demonstrations.
Preliminary schedule:
