How ScaFix plans MJ OPTIMA
2 m lifts; ties every 4 m vertically, every 6.14 m (2 × 3.07 m) / 5.14 m (2 × 2.57 m) / 4.14 m (2 × 2.07 m) along the wall; diagonals at least one per 5 bays in every lift

Wall-tie spacing along the wall for MJ OPTIMA

ScaFix ties MJ OPTIMA every 4 m in height. Along the wall a tie sits on a standard, so the spacing is always a whole number of bays: for a wall built from one bay length, the table shows how many bays lie between two tied standards and the spacing that gives. Rule: DIBt Z-8.22-986 MJ OPTIMA (bis 23.07.2027) Anlage B §B.5 a. ScaFix is a planning tool, not a structural approval.
