## Each item designated for removal shall be classified as remove and salvage, remove and reinstall, or remove and legally dispose.
−### These three dispositions drive entirely different handling, documentation, and storage obligations. "Save the light fixtures" stated verbally and undocumented is the classic dispute generator; the disposition belongs on the drawings, item by item. {note}

## The demolition configuration shall be selected to match the structural role of the removed elements and the sensitivity of adjacent retained work.
−### Non-structural partition stripping, structural element removal, facade selective demolition, roof cut-outs, and MEP demolition each carry different engineering, protection, and sequencing burdens. The configuration set on this datasheet drives whether engineer-stamped shoring, temporary weather protection, or negative-air containment is mandatory. {note}

## The cutting method shall be selected for the material and for proximity to retained construction.
−### Saw-cutting gives clean, controlled edges next to work that remains; mechanical breaking is faster but transmits impact and vibration; hand tools are mandated near fragile or character-defining features. The choice is a trade-off between speed and the energy delivered into adjacent construction. {note}

## The dust containment method shall be selected for the class of contaminant generated by the removal.
−### Hoarding alone suffices for clean inert debris; wet suppression controls nuisance dust; a negative-air enclosure with HEPA filtration is mandatory wherever regulated asbestos or lead may be disturbed. Under-specifying containment spreads contamination through occupied space; over-specifying wastes schedule. The contaminant class, not preference, sets the method. {note}
