Cliff Bishop

Licensed Professional and Structural Engineer, at Exponent, Inc.

Dr. Bishop specializes in the holistic evaluation of building and bridge structures. While at Exponent, he has led investigations of concrete, steel, wood, and masonry structures and their interior finishes and building envelope components that were damaged as a result of design/construction defects, construction procedures, and natural hazards, such as wind, floods, hurricanes, and earthquakes. These investigations typically include on-site testing and documentation, analysis of structural and non-structural component response, interpretation and application of building codes and standards, and identification of the most appropriate repair. He often employs sophisticated engineering analysis and state-of-the-art research in support of these investigations. Dr. Bishop sound engineering advice provides the basis necessary for building owners, insurers, and other stakeholders to make informed decisions.

Course Title: Moisture-Resistant Buildings

Delivery Method: Live Online

Course Description: This six-hour course examines the science of moisture intrusion, movement and consequences, analyzes guidance provided by building codes and standards, and assesses the performance of moisture-resistant foundations, wall systems and roofing systems. The course concludes by examining mechanical systems that can be utilized to control moisture.

Learning Objectives:

Learning Objective 1:
Learners will be able to explore the sources and effects of interior moisture in buildings, identifying potential risks such as mold growth, energy loss, and damage to building systems and materials.
