Marine Reserve Base

Steel Welded Stair Case Study: U.S. Marine Reserve Base


Construction crews needed floor-to-floor access as they erected the 400,000-square foot, 4-story U.S. Marine Reserve Base.


Lapeyre Stair shipped the first stair tower early to provide crews with floor-to-floor access. Subsequent stair stystems were delivered in stages.
