Layher Allround parts list for a house elevation

Before you rely on this guide

This guide summarises published rules to help you plan and is not legal advice. It has not been reviewed by a qualified scaffold designer or engineer. ScaFix is a planning aid, not structural approval: the manufacturer's instructions, the scaffold design and a competent person's inspection decide what is built and used on site.

How does 8.5 m become three bays?

Layher Allround’s common bay lengths are 3.07 m and 2.57 m. Three long bays would be 9.21 m, two would be 6.14 m. The engine fills the elevation with 1 × 3.07 m + 2 × 2.57 m, 8.21 m in all, just under the 8.5 m wall: each end of a lift stops roughly 15 cm short of the corner, which is still within reach from the deck. Three long bays would overshoot the wall by about 70 cm. One bay is longer than the others, which means two lengths of ledger, deck, guardrail and toe board on the order.

With the eaves at 5.2 m, the scaffold has two working lifts, at 2.25 m and 4.25 m. The top lift sits below the eaves so the roofline is in reach without the lift clashing with the gutter.

Parts list: Layher Allround, one elevation 8.5 m × 5.2 m

Computed by ScaFix’s engine for exactly this job, with the system’s own bay lengths and rules. Corners are in the list only where the job is a whole house; openings, sheeting, hoists and loading bays are not. The manufacturer’s instructions decide: this is a planning aid, not structural approval.

Why does each line have the number it has?

Four standard lines (three bays plus one), each with an inner and an outer standard, and three ledger levels (the base and two working lifts) explain almost the whole list:

The bracing rule is Layher’s own: “Stiffen at least every fifth bay with vertical diagonal braces”, preferably on the outside (Layher Allround, Instructions for Assembly and Use 04.2018, p. 22).

How does the list change for other houses?

A narrower front, 6.5 m, takes two long bays and 108 pieces; a wider one, 10.5 m, four short bays and 178. Width adds standard lines and bays; height adds whole lifts. Taking the same 8.5 m front up to 7.5 m eaves, a third lift, gives 182 pieces.

Same system, same engine: the elevation’s width and the height to the eaves changed.

Which UK rules apply on top of the list?

• Guardrails and toe boards. The Work at Height Regulations 2005 require the top guardrail to be at least 950 mm above the edge, an intermediate guardrail so that no gap exceeds 470 mm, and toe boards suitable and sufficient to prevent falls of people and materials (SI 2005/735, Schedule 2). Allround’s three-part side protection, top rail, mid rail and toe board, is what the guardrail and toe board lines provide.
• Manufacturer’s instructions. HSE’s position is that system scaffolds are erected to the manufacturer’s instructions, anything outside them needs a design, and the scaffold is inspected after installation, at intervals of no more than 7 days, and after anything that could affect it (HSE: Scaffolding). NASC TG20 is for tube and fitting scaffolds, not for Allround.
• Distance from the wall. Layher notes that once the clearance between the building and the deck exceeds, for example, 30 cm, side protection may be needed on the inside too (Layher, p. 11). On a front with deep window reveals or external insulation, plan inside brackets or an inside guardrail.
• Hoisting. Layher recommends a building hoist for erection when the deck height exceeds 8 m, unless the scaffold is no more than 14 m high and 10 m long (Layher, p. 22). A two-storey elevation is well under that.

What is not on the list?

• Corners and returns if the scaffold wraps round to a side elevation.
• A loading bay for materials, and the extra ties it needs.
• Sheeting or debris netting, which raise wind loads and need more ties.
• Brackets for wide eaves or insulated walls.
• Sole boards under the base jacks, and transport.

This is a planning aid, not structural approval. Layher’s instructions for assembly and use, HSE guidance and a competent person’s inspection decide how the scaffold is built and used.
