38 Student Lessons Learned The United States has some ground to make up in the mass *mber design and construc*on field compared to Europe and Canada It is currently easier for students to use known structural systems in design steel and concrete, rather than advance the conversa*on on mass *mber What are the current fire ra*ng standards for mass *mber construc*on? Which applica*ons are preferred for which parts of a structure: CLT, NLT, Glulam etc? How can we make it easier to find informa*on?
