How ScaFix plans WACO RED Access Frame: 2.01 m lifts; ties every 4 m vertically, every 3.05 m (1 × 3.05 m) / 4.88 m (2 × 2.44 m) / 4.27 m (2 × 2.13 m) along the wall; diagonals at least one per 1 bays in every lift

Wall-tie spacing along the wall for WACO RED Access Frame

ScaFix ties WACO RED Access Frame 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: Waco RED frame scaffolding brochure ORN1701 (BrandSafway 2020) p. 20 «Scaffolding Safety Guidelines» F (SSFI): first tie at 4 × the minimum base, vertical ≤ 26 ft (7.9 m), at each end and ≤ 30 ft (9.1 m) along. ScaFix is a planning tool, not a structural approval.

US rules for WACO RED Access Frame (OSHA 29 CFR 1926.451)

Height-to-base for WACO RED Access Frame: planned 5' (1.52 m) wide, it must be restrained by guying, tying, bracing or an equivalent means above 4 × that width, 20' (6.10 m) — §1926.451(c)(1).
Ties for WACO RED Access Frame: at horizontal members that support both inner and outer legs, placed as the manufacturer recommends or starting at the horizontal member closest to that height, then repeated vertically every 26 ft (7.9 m) or less, because the scaffold is wider than 3 ft (0.91 m), and at each end and horizontally every 30 ft (9.1 m) or less from one end — §1926.451(c)(1)(i)–(ii).
Guardrails on WACO RED Access Frame: the top rail 38 to 45 in (0.97–1.14 m) above the platform on scaffolds made or placed in service after 1 January 2000, with a midrail about halfway — §1926.451(g)(4).
Toeboards on WACO RED Access Frame, where they are needed against falling objects: at least 3½ in (89 mm) high — §1926.451(h)(4).
ANSI/ASSP A10.8 is the US consensus standard for scaffolding safety; the manufacturer's instructions apply on top of both.
ScaFix is a planning tool, not a structural calculation or approval. A competent person must check the scaffold before use.
