Abstract: A system for raising and lowering a building relative to its foundation. A plurality of permanently-installed lifting apparatuses engage the building or a building support structure and exert an upward force causing the building to be moved vertically relative to the foundation.

Abstract: An apparatus, system and method for raising and lowering a building, wherein a yoke receives the end of a building lifting beam and travels vertically on a vertical guide. The yoke is connected to a jack, and the yoke and jack are provided with independently releasable locking means. In operation, the jack is locked on the guide at an initial supporting position to allow the yoke to move, and then the yoke is locked on the guide to allow the jack to move to a new supporting position on the guide, allowing the yoke to climb up and down the guide through alternating component lockings and movements.

Abstract: An apparatus for lifting and lowering buildings includes first and second beam support frames. Each support frame includes a horizontal base adapted to rest on the ground, a vertical beam guide extending upward from the base, a beam support member engaged in the vertical beam guide such that the beam support member moves substantially vertically up and down in the beam guide, and a jack mechanism operative to move the beam support member up and down. A beam having a length selected for use to raise a selected building has a first end supported by a beam support member of the first support frame, and a second end supported by a beam support member of the second support frame.
