Method for supporting a structure

A method of elevating a portion of a building surface above a fixed surface, the method comprising the steps of:

• providing a support pedestal comprising a base member having base threads, a support member having internal support threads and external support threads, and a height-adjusting member having a first threaded cylindrical engagement portion that is adapted to rotatably engage with the base threads and having a second threaded cylindrical engagement portion that is adapted to rotatably engage with the internal support threads to operatively interconnect the base member and the support member;
• positioning the base member on the fixed surface;
• rotating the height-adjusting member relative to the base member or the base member relative to the height-adjusting member to rotatably engage the first threaded cylindrical engagement portion with the base threads until the height-adjusting member is in threaded engagement with the base member;
• rotating the height-adjusting member relative to the support member or the support member relative to the height-adjusting member to rotatably engage the second threaded cylindrical engagement portion with the internal support threads until the support member is in threaded engagement with the height-adjusting member;
• rotating the base member relative to the support member or the support member relative to the base member until the external support threads are rotatably engaged with the base threads;
• and
• placing the portion of the building surface on the support member.
