Abstract: An adjustable construction support apparatus includes a poured concrete footing assembly and a tube assembly retained in the footing assembly. A threaded collar is attached to a top portion of the tube assembly. A threaded shaft has complimentary threads to the threaded collar, and the threaded shaft is received by the threaded collar such that a lower portion of the threaded shaft extends into the tube assembly. A nut is welded to the threaded shaft and is adapted for receiving a wrench for applying a torque for rotating the threaded shaft. A swivel assembly is connected to an upper portion of the threaded shaft, and a bracket assembly is attached to the swivel assembly. The bracket assembly is adapted to engage a portion of a structure. The tube assembly includes a disparate diameter region adapted to receive a portion of the footing assembly such that the tube assembly is secured in the footing assembly and is prevented from moving vertically in the footing assembly.
