#occupational/takeoff
This week (2025w51)
William Bonn, as part of [[units-takeoff]] for Howard University East Towers,
used an `Area` "Typical - Unit Balconies" for `Phase` "UNIT - RESIDENTIAL" takeoff.
Our senior Joel Jansen approved of the method.
I'd like to use the method tentatively for takeoff strictly typical of all units
(e.g. master switches, MSDE's, etc.),
but there is potential for significant efficiency gains
in treating units like panelboards in [[switchgear-takeoff]]:
picking one unit type to be typical of many nearly identical types.
