Independent Tied Scaffolds
An independent scaffold consists of a double row of standards, with each row parallel to the building. The inner row is set as close to the building as is practicable. The distance between the lines of standards should be the minimum necessary to accommodate the required number of boards and toe boards.
A variation may be adopted in which the row of standards nearest to the building can be set back about 300 mm from the building face. This means that one of the boards of the platform can be laid between the inside row of the standards and the building face.
The standards should be connected with ledgers parallel to the building and fixed with right angles couplers. Transoms are then fixed to the ledgers with putlog couplers to support the recommended platform widths.
Sole boards and base plates should be used under each standard as recommended.
Ledger bracing is generally fixed to alternate pairs of standards.
Sway bracing is required at intervals not exceeding 30 M.
The scaffold should be tied into the building at the frequency recommended.
