Selective demolition
Definition: The careful, targeted removal of specific building components — finishes, non-structural walls, fixtures, cabinetry, flooring — while preserving the structural frame and systems that will remain. In renovation, selective demolition serves two purposes: clearing the way for new work and revealing existing conditions behind finished surfaces. It is often the first construction activity and the point at which concealed conditions are discovered. Hazardous-material testing (lead, asbestos) must occur before selective demolition disturbs suspect materials.
