Vertical construction adds a dimension general laydown-yard lighting planning doesn't need to consider: work is spread across multiple floors simultaneously, connected by stairwells and hoistways rather than open ground.
Unlike a single-level site where one lighting plan covers the whole active work area, multi-story construction has work progressing on several floors simultaneously — slab pours on one level, MEP rough-in on another, finishing work on a third. Each level effectively needs its own lighting plan rather than one plan covering the whole project.
Before permanent elevators or hoists are operational, equipment moves between floors via stairwells or temporary hoists — weight and single-person portability matter directly here. A compact, light unit that one person can carry up a stairwell has a real practical advantage over heavier equipment needing a hoist or multiple people just to relocate a level.
Stairwells, temporary hoistways, and floor-to-floor access routes are their own hazard zone, distinct from the active work floors themselves — see our night construction safety guide for why access routes need dedicated coverage rather than relying on spillover from work-area lighting.
Early in a build, before exterior walls or partitions exist, floor plates can be relatively open — but as the structure closes in, work areas become more compartmentalized and confined, closer to the confined-space lighting case than open laydown-yard lighting. See our confined space lighting guide for that transition.
The LI-300's light weight and fast single-person deployment suit floor-by-floor redeployment and stairwell transport. The LI-TP-200 suits more confined, compartmentalized spaces as a structure closes in.

Yes — early open floor plates shift toward more compartmentalized, confined spaces as walls and partitions go up, closer to a confined-space lighting case.
