On a residential site, the priorities are usually noise, access, and keeping the mess contained — a single narrow staircase or a tight side gate can shape the whole job plan more than the cutting itself.
On a commercial site, the scale changes: larger openings, thicker slabs, more coordination with other contractors on site, and often work scheduled around business hours to avoid disrupting operations.
The core skill — accurate, controlled diamond cutting — stays the same in both cases. What changes is the planning around it: access logistics for a villa, and scheduling and coordination for a commercial or industrial site.
