WACO systems in ScaFix

The bay lengths and depths are every size the catalogue offers for the system, across its variants. «Approval» is the number the system’s tie rule cites; «–» means the rule cites a manual or no document.
System	Type	Bay lengths	Depths	Approval
Waco Frame	Frame	3.05 m, 2.13 m, 1.52 m	1.52 m, 0.91 m	–
WACO Narrow Frame	Frame	3.05 m, 2.44 m, 2.13 m, 1.52 m	0.7 m	–
WACO RED Box Frame	Frame	3.05 m, 2.44 m, 2.13 m, 1.83 m, 1.52 m, 1.22 m	1.52 m, 0.91 m	–
WACO RED Access Frame	Frame	3.05 m, 2.44 m, 2.13 m, 1.83 m, 1.52 m	1.52 m	–

WACO systems on the same example house

Each system planned on ScaFix’s example house (11.4 m × 5.3 m) with the default settings. The totals differ with bay length, depth and part design; a lower total is not better by itself. How the example is set up is on the methodology page.
System	Long-wall bays	Depth	Parts in total
WACO RED Access Frame	5	1.52 m	340
WACO Narrow Frame	5	0.7 m	348
Waco Frame	6	1.52 m	352
WACO RED Box Frame	5	1.52 m	370
