Abstract
A multilevel modular building with scissor stairs and a method for constructing such a building is disclosed. The scissor stair comprises a pair of stairways connecting the floor of a module on a lower level with the floor of a module directly above. The stairways are disposed adjacent to each other in parallel vertical planes and configured in an X shape. A fire wall separates each stairway. In this manner, the stairways of the present invention provide the upper level with two separate and remote routes for access or egress in a minimal amount of space.
