On a multi-family or mixed-use project you are usually the first consultant hired and the last one standing. Early on you test massing against the rules: height, density, setbacks, parking, and what the Official Community Plan intends for the site. You draw a schematic design, sit down with planning staff at a pre-application meeting, and start pulling together a team of consultants who each need a stable set to work from.
Through rezoning and the development permit, your job is persuasion as much as design. You write the design rationale, present to an advisory design panel where the municipality has one, answer staff comments round after round, and revise. Every revision ripples outward: the landscape plan, the shadow study, the renderings and the developer's pro forma all have to catch up with your latest set.
Once the permit is issued, design development and construction documents take over, then tender and site questions from the builder. By then marketing is already selling your building with images. The gap between what you approved and what the public sees is where architects lose the most sleep, and it is the gap a shared record closes. See how that record works on Order & review.
A useful habit: treat visuals as part of the drawing set, not an add-on. Decide at schematic design which views matter for staff, council and sales, and keep those camera positions through every round. Comparing the same view across versions shows what changed faster than any memo, and it protects you when someone asks, months later, what was actually approved.
