2 Credit(s) earned on completion of this course will be reported to AIA CES for AIA members. Certificates of Completion for both AIA members and non-aia members are available upon request. This course is registered with AIA CES for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product. Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.

3 Course Description With so many compelling reason to build with mass timber the question is no longer why? but how?. As a construction method in its own right, mass timber construction has its own rules and regulations which need to be understood by all if mass timber is to achieve its potential of becoming the construction method of choice for most building types. This presentation will discuss focus on best practice in terms of design, procurement and construction through a number of case studies of recent projects that Eurban have been involved in.

4 Learning Objectives At the end of the this course, participants will be able to: Key learning points: KEY LEARNING OBJECTIVE 1 Understand what is being done in the UK in order to optimise the delivery of mass timber projects in terms of design and construction. KEY LEARNING OBJECTIVE 2 Understand the role of a CLT designer / specialist contractor on mass timber building projects and how knowledge and experience can inform design decisions and help deliver such projects effectively and safely. KEY LEARNING OBJECTIVE 3 Understand the risks associated with the design and delivery of large-scale mass timber buildings and how one might overcome such risks KEY LEARNING OBJECTIVE 4 Understand how mass timber construction differs from concrete construction and stick build construction, particularly in terms of the perceived risks of fire and moisture, and how to design for them.

7 Architecture should be about satisfying a social need, not about addressing a financial condition. Using natural materials will escape the constraints of speculative industries, and return to a socially-alert, environmentally sustainable architecture. Gilles Perraudin, 2013
