The document summarizes structural aspects of the David O McKay Building at Church College of New Zealand. It describes the massive trusses used between the gym and auditorium, as well as cross bracing elements and spacing blocks welded between cross members to brace against lateral loads from seismic events. Photos show the bottom connections of the trusses to reinforced concrete beams and pillars, indicating the building was designed to withstand seismic events in addition to wind loads.
