Abstract: A pipe-support system including a pipe-support frame structure having plural, substantially horizontal, pipe-support levels supported by columns including a distribution of side columns uniformly spaced along at least one side of the frame structure, and featuring selectively graduated, support-level-indifferent, lateral-connectivity access for quickly available, removeable, outrigger gravity attachment to the frame's side columns, through gravity catch and hook structures, of modular, outrigger, lateral, worker-platform scaffolding either as individual scaffolding units, or as assemblies of plural, individual units, all such units deriving vertical support through outrigger connections made to the frame structure.
