A one-piece, Z shaped steel plate foundation comprising a main plate body extending the longitudinal length of the foundation from a top to a bottom of the foundation, a single rear flange extending perpendicular to the main plate body in a first direction at a rear edge of the main plate body, wherein the single rear flange does not extend past the main plate body in the direction opposite the first direction, a single front flange extending perpendicular to the main plate body in the direction opposite the first direction at a front edge of the main plate body, wherein the single front flange does not extend past the main plate body in the first direction; and a plurality of mounting holes at the top of the one-piece metal plate foundation configured for attachment to the structure to be supported.

A measuring device and method for horizontal dynamic impedance of specified foundation depth based on differential response analysis of pulse excitation. The measuring method is realized based on the measuring device. Two rigid piles with different lengths are embedded into different foundation depths. Motion characteristics of the two rigid piles in the process of collision impact with the outside are different under the same pulse excitation. Dynamic impedance of specified foundation depth is deduced from the formula according to the differential response. Single-degree-of-freedom oscillators are arranged on the pile heads of the two piles, and strain gauges are arranged on the bottoms of the single-degree-of-freedom oscillators to obtain stress states of the single-degree-of-freedom oscillators, thereby calculating the relative displacements of the single-degree-of-freedom oscillators. This is simple in structure, reliable in measurement and convenient in data collection and processing.

A method for installing and deploying concealed mounting points for a davit or jib crane on a roof patio or large balcony covered with stone pavers. Specifically, a metal plate assembly lower flange is affixed to the concrete roof slab with its contact points covered by waterproofing membrane. The metal assembly hard point upper flange holes correspond to the holes in the mounting base of the davit or jib crane. The metal assembly when installed is lower than the pavers supported by metal pedestal transition components. As such, the metal assembly hard point is concealed and covered by a removable cover plate that also sits on top of the metal pedestal transition components and is flush with the top of the pavers.
