HAKI systems compared head to head

Every pair of HAKI systems in the ScaFix catalogue: which bay lengths and depths they share, which only one of them has, and what the planning engine counts for each on the same example house, parts group by parts group.

How do the HAKI systems differ?

ScaFix has 2 HAKI systems: HAKI Ram and HAKI Universal. On the same example house (11.4 m × 5.3 m), HAKI Ram needs 220 parts and HAKI Universal 652. Bay length, depth and part design set the totals; they say nothing about price or load class. ScaFix is a planning aid, not a structural approval.

Pair by pair: bay lengths and depths

Each pair of HAKI systems, from the catalogue the engine plans with. «Only in» lists the bay lengths one system has and the other lacks; the last column is the parts total of each on the example house.

HAKI systems compared head to head
Pair	Type	Shared bay lengths	Only in the first	Only in the second	Shared depths	Parts on the house
HAKI Ram – HAKI Universal	Different types: Frame / Wedge	3.05 m, 2.5 m	1.66 m	–	0.7 m	220 / 652

Parts group by group on the same house

Each HAKI system planned on ScaFix’s example house (11.4 m × 5.3 m) with the default settings. The rows are the groups of the app’s parts list; «–» means the system has no part in that group. How the example is set up is on the methodology page.

Questions and answers

Can I mix parts from two HAKI systems in ScaFix?

No. ScaFix plans each wall with one system’s own parts and never mixes systems in a parts list. Whether two systems of one maker may be combined on site is for HAKI’s instructions to say. ScaFix is a planning aid, not a structural approval.

Why do the parts totals of the HAKI systems differ?

A wall is filled with each system’s own bay lengths, so a shorter bay means more bays, standards and ledgers; the depth changes the transoms and decks, and frame systems count frames where modular systems count standards and ledgers. The totals say nothing about price or load class.
