What kind of commercial project?
Pick the closest match. Drives system recommendation and the per-SF base.
How tall is the building?
Height drives both the recommended system and the install cost factor (high-rise needs unitized, cranes, and sequencing).
How big is the scope?
Pick whichever you actually know. They all work — the engine converts to system area in the background.
Counts framing + glass together, not vision-glass only. Most accurate input the engine accepts.
Where is the project?
Florida HVHZ + wind speed varies wildly by county. Picking the right region applies the right code framing and cost factor.
Special requirements?
Pick any that apply. Each affects the price — you'll see exactly how on the results screen.
Glass makeup tier?
If you've talked to a designer about a specific tier, pick it. Otherwise leave the default — the engine picks per region and project type.
