This part of BS 1139 specifies requirements for the structural design of prefabricated tower scaffolds utilizing components from mobile access and working towers specified in BS EN 1004 but in configurations that are outside of the scope of that standard.
These configurations include:
-
prefabricated tower scaffolds outside the height limits of BS EN 1004;
-
towers with more than one working platform;
-
large deck tower scaffolds;
-
linked tower scaffolds;
-
cantilever tower scaffolds;
-
stepped tower scaffolds;
-
tower scaffolds used as a means of access;
-
towers built on base plates instead of castors.
This British Standard applies to prefabricated tower scaffolds subject to wind loads up to and including 0.1 kN/m2.
NOTE Where a prefabricated tower scaffold might be subject to wind in excess of 0.1 kN/m2, and it cannot be dismantled or moved to avoid these winds, suitable wind design criteria can be found in BS EN 1991‑1‑4.
This British Standard does not cover prefabricated tower scaffolds using guys as a method of stabilization.
