CS2.1: Bridging the gap

Friday, November 15, 2024
8:30 AM – 10:00 AM EST
CE: 1.5

General Admission/Adminsion générale Simultaneous Interpretation Available/Interprétation simultanée disponible AIA CES Approved

This session has qualified for 1.5 LU|HSW Credits

Starting with some explosive examples of why mortar matters, moving to new uses in old barns, shaking it up with how we want old masonry to survive, well, shaking, then rounding out the session with finding one solution to many problems – this technical session is all about bridging some of the many gaps we see in our industry.

From an engineer’s perspective we look at ways to bridge the gap between actual performance of existing buildings and other practices that can cause problems. Looking at how to bridge the gap between existing buildings and what may be needed for a new use, and providing ways to overcome the technical obstacles that trouble many projects. This means looking at how to bridge those gaps between contemporary codes and frameworks with buildings that have demonstrated ability. But mostly we are aiming to bridge the gap between what are effective highly technical approaches specialists use and the decision makers or owners that often make decisions directing resources. Our presenters have a mix of backgrounds and case studies that can help challenge the status quo by demonstrating what can be done with these buildings we find so interesting.

HSW Justification
Key focus is on keeping buildings from collapsing on people while meeting overall conservation objectives of a project, as well as prolonging and extending the use of an existing building. These presentations focus on the special considerations impacting the structural integrity of a specific type of building (barns), and improving the structural performance of building materials and assemblies during seismic events, to further prevent loss of life or property.

Learning Objectives:

  • Upon completion participant will be able to describe the risk posed by incompatible mortars, and define current state of research for mortar compatibility.
  • Upon completion participant will be able to define the differences between Farm and Building codes and describe key considerations of a barn rehabilitation project.
  • Upon completion participant will be able to describe the process for seismic evaluation and upgrade for unreinforced mortar, demonstrating specialists inspired guidance to their projects.
  • Upon completion participant will be able to describe and defend low cost retrofit strategies to rehabilitate unreinforced masonry buildings.
