Sub-Slab Drainage Systems: Design and Construction Considerations
Many buildings have enclosed below-grade spaces that can be exposed to permanent, temporary, or perched groundwater conditions. These groundwater elevations can fluctuate several feet, if not more, due to precipitation or tidal influences. Groundwater infiltration into these below-grade spaces, or worse, a buoyancy failure of the basement slab, can result in potentially costly problems for building owners and tenants if not handled appropriately.
Failure to adequately address high groundwater conditions can lead to the disruption of building operations, damage to interior finishes, deterioration of structural and mechanical components, and potential interior air quality issues. Unfortunately, it is not always clear who should lead the design efforts, since architects and plumbing, geotechnical, structural, and civil engineers may all be involved in the system design. In this webinar, we will focus on the design elements of sub-slab drainage systems and the multidisciplinary design considerations that are critical to successfully executing its design and construction.
LEARNING OBJECTIVES
After attending this webinar, participants will be able to:
- Identify the components of sub-slab drainage systems.
- Understand when these systems are necessary.
- Discuss the design roles and responsibilities for these systems.
- Review commonly encountered construction conditions.
Participants will earn 1.0 AIA CES Learning Unit (LU/HSW) for attending the live webinar. Registration is free. Please note that space is limited – email events@sgh.com to join our waitlist if the session is closed when you register.
About the Speaker
Zachary Boswell is a geotechnical engineer with experience in subsurface explorations, shallow and deep foundation systems, site characterization, temporary and permanent support of excavation systems, retaining walls, turf fields, groundwater leakage mitigation, soft ground engineering, ground improvement, and forensic investigations for a wide range of infrastructure and development projects. Zachary engages with the geotechnical engineering community and contributes to advancing the profession through his involvement with the American Society of Civil Engineers, the Boston Society of Civil Engineers Section, and the Deep Foundations Institute. He is an active problem solver and collaborator, committed to finding the right solutions and providing his expertise to clients and colleagues to overcome complex geotechnical engineering challenges.
Bryan Strohman has diverse experience in geotechnical, civil, and structural engineering, including investigating, designing, and rehabilitating a variety of structures. His work experience includes mechanically stabilized earth walls, slopes, foundations, piles, excavation support systems, retaining walls, artificial turf fields, drainage systems, buried arches, box culverts, pipes, three-sided structures, bridges, and nuclear facilities. He has performed a number of investigations of mechanically stabilized earth wall failures, foundations, and damage to underground structures. His technical expertise is focused on heavy civil structures, soil behavior, and drainage systems. His broad experience has also involved numerous soil-structure interaction analyses. He is an active participant in the American Society of Civil Engineers’ Embankments, Dams, and Slopes Committee, and currently serves as the committee secretary. He is also a member of the Deep Foundations Institute’s Codes and Standards Committee and the Boston Society of Civil Engineers Section Geo-Institute Technical Group.
