Presenters, Presentations, and Learning Objectives


“Assessing Retrofit Single Ply Roof Systems Installed Over Existing Metal Panel Roof Systems” (1.0 CEH)

Metal buildings with metal panel roof systems are commonly used across the United States, and a retrofit single-ply roof system is frequently installed after the metal roof is no longer providing useful service.  Research has been conducted to experimentally and analytically investigate the performance of metal panel roofs retrofitted using single-ply roof systems.  Various large-scale assemblies were subjected to an industry-recognized uplift-resistance test to determine uplift resistance and mode(s) of failure.  Variations in fastener schedules and type were also evaluated using finite element analysis (FEA) models that were developed and calibrated by experimental testing.  Of specific concern are differences in uplift resistance of retrofit single ply roof systems because of variations in attachment, including fastener types, schedules, and spacing of existing structural members.


Learning Objectives

  • Review and classify current industry practices for retrofit single ply roofs.
  • Discuss the research parameters and results of physical testing of retrofit single-ply roof systems installed over metal panel roofs.
  • Understand the different failure modes and uplift-resistance differences because of variations in the structural attachment of retrofit single ply roofs.
  • Identify the structural concerns of the existing purlins when changing the uplift load path.
  • Recognize best practices for retrofit single-ply roofs over existing metal panel roof systems.

“Plaza Waterproofing: Applying Fundamentals from Failed Investigations to Rehabilitation Design” and “Integrating Tunnel Waterproofing with Slurry Wall Construction: Site, Material, and Workmanship Considerations” (1.0 CEH)

More and more buildings are being constructed adjacent to existing buildings and further into the soil and likely into groundwater. Designing new buildings adjacent to existing construction can present significant waterproofing integration challenges. Not only is leakage through buried plaza and foundation systems detrimental to the building structure and occupants, identifying and repairing buried waterproofing conditions is difficult and cost prohibitive. Additionally, the existing adjacent system’s materials and configurations amplifies the challenges when integrating new to existing waterproofing systems. This presentation will focus on how fundamentals learned from investigations of leaking plaza systems can be applied to appropriately detail vulnerable transitions to adjacent plaza systems. Fundamentals we will review include drainage, waterproofing membrane options, and design of penetrations and terminations. The presentation will also review waterproofing a connector tunnel and detailing the intersection to an existing slurry wall. We will review how the geotechnical report should be used to inform the waterproofing selection. We will review blind-side, positive-side, and other foundation waterproofing systems and the design of critical transitions to adjacent systems.


Learning Objectives

  • Review fundamentals for plaza waterproofing systems learned from leakage investigations such as drainage level, waterproofing membrane options, and detailing critical conditions.
  • Select appropriate waterproofing basis-of-design materials and systems for integration between new and existing membranes.
  • Coordinate waterproofing installation with existing materials and configurations.
  • Understand significance of the geotechnical report.
  • Understand waterproofing and flashing configuration for connector tunnel through a slurry wall.

“Enclosure Failures” (1.0 CEH)

Mr. Rutila will present selections from over 30 years of enclosure failure investigations, with emphasis on failures that are relevant to professionals in today’s building construction industry. The inevitable question: Why did “it” break?


Learning Objectives

  • Review fundamentals for various building enclosure systems, focusing on wall construction, learned from failure investigations such as air and vapor barrier membrane options, and detailing critical conditions.
  • Select appropriate building enclosure basis-of-design materials and systems for integration between new and existing systems.
  • Coordinate installation with existing materials and configurations.
  • Understand impacts of building science issues with regards to enclosure failures.
