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.
