Annual Meetings-Mass Timber/ CLT

Pdf Summary

Mass timber, including Cross-Laminated Timber (CLT) and Glue Laminated Timber (glulam), is being increasingly used in construction projects to reduce carbon emissions. Odeh Engineers developed different structural schemes for a mid-rise residential building in Boston, featuring various levels of carbon reduction using mass timber and hybrid steel frames. Polls reveal concerns about fire, water damage, and lack of experience with mass timber. The Mass Timber Project Life Cycle involves material and code selection, design, fabrication, shipping, and construction. Mass timber products must meet manufacturing standards and adherence to building codes. Currently, there are 1,677 mass timber projects in the US, with various tall mass timber buildings completed or in the design phase. Extensive fire testing has been conducted on mass timber elements, assemblies, connections, and more to ensure fire performance. Key early design decisions and engaging manufacturer partners are crucial in utilizing mass timber efficiently. Understanding manufacturing capabilities, virtual modeling, and quality control are essential aspects of mass timber construction projects. Proper moisture management and protection are vital considerations in utilizing mass timber effectively.
