ExAC study notes · one summary per exam
The must-know of each ExAC exam.
Section 1Design & Analysis
Programming, site analysis, engineering coordination, cost, schematic and design development.
Six topics, one workflow: program → site → schematic → engineering → cost → design development. Questions test process and sequence, not design talent.
Net-to-gross by occupancy: office 65–75%, residential 60–70%, education 60–70%, healthcare 50–65%, lab 50–60%.
Match the cost method to the phase: order-of-magnitude in SD, Class A at tender; sort costs with the Yardsticks elemental categories.
The architect coordinates and integrates; each engineer owns their discipline. When two answers fit, pick the one that documents, verifies or consults first.
