A comprehensive understanding of the schedule associated with the construction of mass-timber versus typical concrete structures provides important data metrics for teams deciding on utilizing this material and method. This study compares simulated manpower loaded schedules of traditional concrete construction applications with that of a real-time, mass-timber construction project. The study produces practical outputs that highlight schedule efficiencies in mass-timber applications, when compared to cast-in-place concrete method. The study found that the mass-timber crew erected 2,323 square feet of structure per day, while a concrete crew would erect 1,825 square feet per day. Additionally, the study found that the concrete crew had more than twice as many workers as the mass timber crew with less production.Keyphrases: concrete, cross laminated timber, glue laminated timber, manpower, mass timber, productivity In: Tom Leathem, Wes Collins and Anthony Perrenoud (editors).
