Intermediate Scaffolding (SI) case studies
Intermediate Scaffolding (SI) · Put your knowledge to work in context.
The Intermediate Scaffolding (SI) high risk work licence is a NSW credential that sits between basic and advanced scaffolding. It is intended for people who build, alter and dismantle intermediate scaffolds on construction and industrial sites, and who need a licence to work in that class. The Intermediate Scaffolding (SI) case studies are 5 cases and about 2,996 words.
1Licence scope and the mixed crew on a school refurbishment
A two-storey school refurbishment requires a 9 m high scaffold along one elevation, plus a 3.5 m tower inside the hall and a 2 m guard-rail frame at a loading dock. The site supervisor holds a basic scaffolding certificate; a labourer holds an intermediate certificate; the leading hand's intermediate certificate expired five weeks ago and renewal is booked next month.

A 12 m long, 8 m high scaffold is to be built along the face of a building, but a 2.5 m deep service trench runs parallel to the wall for 5 m of that length, leaving about 1.2 m of level ground between the trench edge and the scaffold's base. The designer's generic drawing shows ties at every second lift and every third bay, with base plates on timber soleboards.

An intermediate scaffold sits over a busy city footpath, with a covered walkway at ground level and a 4.5 m clearance to a 11 kV overhead line running diagonally above one corner. The scaffold has been up for four months and is now to be partly dismantled so the facade below can be rendered, then re-erected.

A scaffold was handed over three weeks ago for a crew of roofers. On a Monday morning the site manager finds that over the weekend someone has removed the internal ladder access hatch and two guard-rails to slide roofing sheets onto the platform, added a plank ramp from the platform to the roof, and hung a gin wheel from a ledger without any bracket.
