Apparatus for raising a building formed of a plurality of modular units. Each module raising unit comprises a rigid, stationary framework supporting a plurality of movable trusses which are raised and lowered relative to the stationary framework by means of a plurality of jacks. The jacks act on the upper portions of the movable trusses, and a principal function of the stationary framework is to provide support for the movable trusses to guard against side forces resulting from wind thrust imposed upon the building during its erection. Preferably, a plurality of hydraulic jacks is employed, but an auxiliary system of mechanical, screw-type jacks is also provided together with an associated followup system to provide support in the event of any failure in the hydraulic system. A supporting structure which includes a plurality of rails is also provided and may be mechanically coupled to each module raising apparatus. Each module may then be equipped with a plurality of flanged wheels which are adapted to ride on the aforementioned rails so that each module may be placed on the supporting structure with the wheels thereof resting upon the rails and with the module then being rolled into place upon the jacking apparatus.
