Wall-tie spacing along the wall for Excel Modular Scaffold

ScaFix ties Excel Modular Scaffold every 6.1 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: Excel Modular Scaffold «Standard Component Technical Manual» Rev. AL § ties, p.109: ties at the ends and ≤ 30 ft along, ≤ 26 ft vertical (≤ 20 ft for ≤ 3 ft wide), first ≤ 4 × base (24" bearer: 2.44 m). ScaFix is a planning tool, not a structural approval.

US rules for Excel Modular Scaffold (OSHA 29 CFR 1926.451)

  • Height-to-base for Excel Modular Scaffold: planned 4' (1.22 m) wide, it must be restrained by guying, tying, bracing or an equivalent means above 4 × that width, 16' (4.88 m) — §1926.451(c)(1).
  • Ties for Excel Modular Scaffold: 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 Excel Modular Scaffold: 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 Excel Modular Scaffold, 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.
