Scaffold system

DELTA 73 in ScaFix

ScaFix plans DELTA 73 scaffolding with the system's own bay lengths (0.73–3.07 m) and depth (0.73 m), draws the scaffold in 3D and works out the parts list. Below is our example house with DELTA 73.

DELTA 73 compared with similar systems on the same house

The same example house, computed by the same engine with each system's bay length and default depth. The difference in piece count comes from the bay length, the depth and how the system is built.

DELTA 73: parts by wall size

Scaffold depth 0.73 m, access: decks with ladders. Each wall is a whole number of 3.07 m bays, so the scaffold covers it exactly. One straight wall, no corners.

How to compare the setup

These are fixed ScaFix examples, not customer jobs. Use the wall dimensions and roof shape stated with each example.
Compare the same system variant, bay lengths, scaffold depth, deck heights and access. Matching house dimensions alone do not give matching parts lists.
The displayed quantities are calculated by ScaFix's engine. Check the setup against the manufacturer's assembly instructions and the actual job; a parts list is not a structural calculation.

Limits

The number of wall ties follows the system's tie rule. Their positions must be checked against the manufacturer's assembly instructions.
Round corners, silos and hanging scaffolds are in Pro. A round scaffold is not a standard configuration and needs a calculation or the supplier's documentation. A hanging scaffold (Layher Allround and HAKI Universal) always needs a structural calculation from the supplier or an engineer.

Questions and answers

Which bay lengths does DELTA 73 have in ScaFix?

ScaFix uses the bay lengths 3.07 m, 2.57 m, 2.07 m, 1.57 m, 1.09 m and 0.73 m and the depth 0.73 m for DELTA 73.

How many parts does the example house need with DELTA 73?

With DELTA 73, the 11.4 m × 5.3 m example house needs 284 parts in all, split into the groups in the table. Your own building gets its own parts list.

How many parts does DELTA 73 need for a 12.28 m × 6 m wall?

A 12.28 m long, 6 m high wall with DELTA 73 (4 × 3.07 m) needs 77 parts in all according to ScaFix: 15 frames and standards, 8 decks, 10 base jacks and legs and 14 wall ties and fittings, with decks on 2 lifts. A 30.7 m wall 12 m high needs 320.

Is the DELTA 73 plan from ScaFix approved for erection?

ScaFix is a planning tool, not a structural calculation or approval. Always check the scaffold against the manufacturer's assembly instructions and the rules that apply before you erect it.
