Construction changes the condition of a building system
Renovation, tenant improvement, equipment replacement, and new construction can introduce dust, debris, packaging, temporary protection, and access changes into the air system and mechanical areas. A post-construction cleaning request should begin with what changed, which areas were affected, which systems were operating during the work, and what the owner needs before occupancy or turnover.
The goal is not to make a blanket claim that a building is ready. A useful scope identifies the equipment, ductwork, air handling units, coils, filters, mechanical rooms, and occupied zones that need to be considered. It also states whether the requested work supports a construction closeout, a tenant handoff, a maintenance reset, or a new preventative plan.
