Scaffold system

JUMBO in ScaFix

ScaFix plans JUMBO scaffolding with the system's own bay lengths (3 m, 2.5 m and 2 m) and depth (0.73 m), draws the scaffold in 3D and works out the parts list. Below is our example house with JUMBO.

How many parts does JUMBO need for a house?

ScaFix plans JUMBO with the bay lengths 3 m, 2.5 m and 2 m and the scaffold depth 0.73 m. On ScaFix’s 11.4 m × 5.3 m example house, scaffolded all round, JUMBO needs 308 parts; Jamax needs 268 on the same house.

The system in ScaFix

Manufacturer: JUMBO
System type: Frame scaffold (facade scaffold)
Variants in the system picker: JUMBO Facade
Bay lengths: 3 m, 2.5 m, 2 m
Depths: 0.73 m
Wall-tie rule in ScaFix: The rule has not been checked against the manufacturer's document yet. Check the ties against the instructions. The wall-tie count in the parts list is an estimate from this rule.

The example house with JUMBO

ScaFix's own example: the 11.4 m × 5.3 m house with a gabled roof, eaves 4.5 m and ridge 6 m, scaffolded all round. The numbers below are the app's own, worked out by the same engine as in projects.

System: JUMBO Facade
Scaffold depth: 0.73 m
Decks at: 2.5 m, 4.5 m
Top deck: 4.5 m
Access: Decks with ladders
Parts in all: 308

JUMBO 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.

The example house with JUMBO and similar systems
System	Bays on the long wall	Depth	Parts in all
JUMBO	1 × 2 m + 3 × 3 m + 1 × 2.5 m	0.73 m	308
Jamax	4 × 3 m	0.68 m	268
Layher Blitz	4 × 3.07 m	0.73 m	271

JUMBO: parts by wall size

Scaffold depth 0.73 m, access: decks with ladders. Each wall is a whole number of 3 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 JUMBO have in ScaFix?

ScaFix uses the bay lengths 3 m, 2.5 m and 2 m and the depth 0.73 m for JUMBO.

How many parts does the example house need with JUMBO?

With JUMBO, the 11.4 m × 5.3 m example house needs 308 parts in all, split into the groups in the table. Your own building gets its own parts list.

How many parts does JUMBO need for a 12 m × 6 m wall?

A 12 m long, 6 m high wall with JUMBO (4 × 3 m) needs 83 parts in all according to ScaFix: 15 frames and standards, 8 decks, 10 base jacks and legs and 20 wall ties and fittings, with decks on 2 lifts. A 30 m wall 12 m high needs 350.

Is the JUMBO 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.
