Meok Bs7121 Mcp

csoai-org/meok-bs7121-mcp

Built for UK crane and hiab operators who need to prove BS 7121 compliance before the lift happens, not after the incident. Ten tools cover the enforcement wedge: clause lookup across parts 1/3/4/5/7, lift category classification that triggers Appointed Person signoff, CPA Contract Lift versus Hire triage (the contractual split that decides who pays when things go wrong), ground bearing pressure calculations, exclusion zone validation, LOLER thorough examination scheduling, and CPCS card verification. Connects to the regulations HSE actually prosecutes on: LOLER 1998, PUWER, CDM 2015, and CAA airspace notifications under CAP 1096. Reach for this when you're quoting a job and need to know if you're hiring out kit or planning the entire lift, or when your Principal Contractor asks for an audit pack before you roll on site.

BS 7121 lift-plan compliance for UK crane + hiab operators. Parts 1/3/4/5/7 clause lookup, AP competence, CPA Contract-Lift vs Hire triage, GBP calc, LOLER scheduling. By MEOK AI Labs.

Why this exists

BS 7121 is the UK lift-planning bible. Five parts most operators reference daily. Plus LOLER, PUWER, CDM 2015, CPCS. Mobile, tower, crawler, lorry-loader — every category has its own triage.

Real UK cases this MCP exists to prevent:

Brand Energy & Infrastructure Services UK — £1.6m HSE fine (Nov 2024). Jack Phillips (24) killed Eastbourne. Expired sling + missing exclusion zone.
Baldwins Crane Hire v Vision Modular Systems (ongoing 2026, £951k claim). CPA Condition 9(d) — proves Contract-Lift vs Hire triage at the QUOTE stage is the £100k+ wedge.

This MCP sits ABOVE 3D Lift Plan and Lolerflow — it doesn't simulate; it validates, classifies, and produces audit-quality compliance attestations.
