Abstract
A height adjustable jack piling assembly has a piling with a top and a bottom. A hinge axis is disposed on the top and a bearing plate is disposed at the bottom. A height adjustment mechanism extends upwardly from the bearing plate and through the piling to raise the piling, and the corresponding hinge axis, by operating the height adjustment mechanism from the top. The method includes placing a jack piling assembly and second lower piling, each having a hinge axis, into the earth and operating the height adjustment mechanism of the jack piling assembly to align the hinge axes.
