Construction scaffold: Welded steel tubular modular scaffold with 2"x10" wood plank platforms and toe-boards. 2"x4" lumber guardrails inserted into slots in integral ladders, in conjunction with steel tube cross-bracing provide some, though not adequate, fall protection. Interior structural steel has been sprayed with fireproofing insulation. Cold-formed sheet metal studs will provide support for wall cladding. Ann Arbor, Michigan 2005.
