Our project site includes an existing lab building as well as a modular building (essentially a large trailer) that is temporarily housing expansion of the lab until a new lab building is added to the site. The existing lab building is being reused and expanded. The modular building will be removed once the new lab is occupied.

Is it correct to exclude the modular building from calculations for the percentage of Building Reuse - Maintain Existing Walls, Floors and Roof?
