Webinar – Long Span Mass Timber: Designing the University of Idaho’s New Arena

April 14, 2021 – 12:00 pm - 1:00 pm




Join at 10 am Pacific, 11 am Mountain, 12 pm Central, 1 pm Eastern

The new University of Idaho Central Credit Union (ICCU) Arena will be a showpiece for U of I’s Vandal Athletics program, provide a unique gathering place for sports, concerts and events, and celebrate Idaho’s timber heritage with innovative mass timber construction. Designed as a multi-event and court sport facility, the arena will accommodate 4,000 spectators and include a basketball home court, practice court, locker rooms, conference space, concessions, media room, and offices. The project aims to serve as a national model for the use of mass timber for long-span sport facilities; the design showcases the use of innovative wood materials with a particular emphasis on Idaho forest products. In this webinar, the project’s architect and structural engineer will discuss the unique aspects of designing a long-span mass timber structure. Topics will include code analysis and compliance, detailing considerations at connections, structural design processes for a long-span roof, and designer-manufacturer interface.
