Why construction dust behaves differently from ordinary soil
Ordinary internal soil arrives with people and settles at a predictable rate. Construction dust is fine, abundant and driven by wind, machinery and vehicle movement, and it enters through doors, air intakes and any gap in the envelope. It settles on every horizontal surface including ones that normally need attention monthly, and it returns within hours of being removed while the source is active.
That changes the shape of the work. Instead of cleaning specific surfaces on a cycle, everything needs attention at once and repeatedly. Entry mats saturate, glass hazes, stock and displays need wiping, and floors need more passes. None of that fits inside a visit designed for a normal week, and pretending otherwise produces a premises that looks poor and a provider that appears to be underperforming.
