Site and environmental analysis
Site and environmental analysis is the second pre-design pillar of Section 1. The primary references are CHOP Chapter 5 (pre-design) and the CHING site-planning chapters. The questions in this category test data triage under pressure: given a partial site description, what information drives the next design decision, what is missing, and who confirms it.
The site data inventory to keep in your head
A complete site analysis covers, at minimum: location and address, legal description and lot dimensions, zoning designation and setbacks, height and density limits, easements and rights of way, topography and grades, geotechnical conditions, surface and subsurface hydrology, climate (heating and cooling degree days, prevailing winds, solar orientation, snow loads, rainfall, frost depth), existing vegetation and trees, neighbouring buildings and shadows, services and utilities (water, sanitary, storm, gas, electrical, telecom), vehicular and pedestrian access, transit access, noise sources, environmental hazards (flood plain, contaminated soil, radon), and heritage or archaeological constraints.
Section 1 will not test all of those at once. It will pick two or three from the list, drop them into a scenario, and ask you to identify which constraint drives the next design choice. Build the inventory as a checklist you can run through quickly under exam conditions.
The decision questions Section 1 keeps asking
Site analysis questions usually follow one of three shapes. First: a constraint plus a wrong choice ("the client wants three storeys on a lot zoned for two; what is your next step?"). Second: missing data ("the brief does not mention frost depth; where do you find it?"). Third: ranking ("which of the following constraints most influences building orientation?"). Drill all three shapes against the Site and Environmental Analysis topic page so the recurring patterns are familiar.
