1. A building support system comprising:
a plurality of caissons that extend below building grade to one or more of an engineered depth and a competent subsurface;
a plurality of caisson caps, wherein each of the plurality of caissons is coupled to one of the plurality of caisson caps, respectively, each caisson cap sitting atop each caisson, each caisson cap comprising,
a top plate that includes multiple openings for pouring concrete for the caisson;
a lockout mechanism for locking the caisson to one of a plurality of structural support members of a building module;
a plurality of stabilizing tabs and blocks for mating with the one of the plurality of structural support members of the building module;
a screw sleeve oriented in a center of the caisson cap for accommodating a screw jack that moves up and down substantially along a central axis of the caisson;
a screw jack bearing plate positioned at a topmost point of the screw jack, wherein a plane of the screw jack bearing plate is perpendicular to the central axis of the caisson; and
a module bearing plate coupled to the one of the plurality of structural support members of the building module, wherein the screw jack bearing plate bears on the module bearing plate and supports and raises and lowers the building module when the jack screw is rotated.
