Cdm 2015 Check

CDM 2015 Check

This skill produces a one-page CDM 2015 brief for a UK construction project. It checks F10 notifiability, lists the duty-holders that apply, and produces Pre-Construction Information (PCI) and Construction Phase Plan (CPP) checklists. Advisory only. HSE is the authoritative source. For formal compliance, engage a qualified CDM coordinator or chartered construction professional.

When to Use

• New project scoping, before tender or contract signing
• Tender stage, checking what the client must provide
• Due-diligence review on a project you are about to take on
• Client education, explaining CDM duties to a commercial or domestic client
• Checking F10 notifiability for a project you are mid-way through planning

Workflow

Phase 1, ask project facts.

• Project description and scope
• Duration in working days (elapsed)
• Peak workforce on site at any one time
• Client type: commercial, public sector, domestic (i.e. private householder for their own dwelling)
• Is there more than one contractor on site (including subbies)? Yes/No
• Location and environmental factors (live building, public nearby, rail/road adjacency)

Phase 2, apply F10 notifiability test.

Under CDM 2015 Regulation 6, a project is notifiable to HSE via Form F10 if either:

• It is expected to last longer than 30 working days AND have more than 20 workers working simultaneously at any point, OR
• It is expected to exceed 500 person-days.

If either threshold is met, F10 notification is required. The client is the duty-holder for submitting the F10, but in practice the Principal Designer or Principal Contractor often prepares it.

Reference references/cdm-2015-duty-holders.md for the exact HSE wording and guidance.

Phase 3, list duty-holders.

Apply the CDM 2015 roles:

• Client (always). Domestic clients: their duties pass to the contractor (single-contractor) or Principal Contractor (multi-contractor). Commercial clients: full duties apply.
• Principal Designer. Required when more than one contractor is on site. Appointed in writing by the client.
• Principal Contractor. Required when more than one contractor is on site. Appointed in writing by the client.
• Designers. Anyone preparing or modifying a design, including temporary works designers and specifier-subcontractors.
• Contractors. Anyone managing or carrying out construction work.
• Workers. Operatives on site.

For domestic clients, note the pass-through: duties do not disappear, they move to PD/PC or sole contractor.

Phase 4, produce PCI and CPP checklists.

Pre-Construction Information (PCI): what the client provides to designers and contractors before work starts. Construction Phase Plan (CPP): what the Principal Contractor (or sole contractor) produces before work starts on site.

Phase 5, present result.

Output Template

# CDM 2015 Project Brief

**Project:** {name}
**Client type:** {Commercial / Public sector / Domestic}
**Duration (working days):** {n}
**Peak workforce:** {n}
**More than one contractor:** {Yes / No}
**Prepared:** {YYYY-MM-DD}

## F10 Notifiable?

{Yes / No}

Reason: {Threshold calculation, e.g. "Duration 45 working days with peak 24 workers on site, exceeds the 30-day AND 20-workers test. F10 required."}

## Duty-Holders

| Role | Who | Key duties (summary) |
|------|-----|----------------------|
| Client | {name} | Provide PCI. Appoint PD and PC in writing. Ensure adequate time and resource. |
| Principal Designer | {name / "not required, single contractor"} | Plan, manage, coordinate H&S in pre-construction phase. Prepare PCI. |
| Principal Contractor | {name / "not required, single contractor"} | Plan, manage, coordinate H&S in construction phase. Produce CPP. |
| Designers | {list} | Design to eliminate/reduce risk. Provide information on residual risks. |
| Contractors | {list} | Plan, manage, monitor their own work. Produce RAMS. |
| Workers | n/a | Take care of own safety. Report risks. Cooperate. |

- [ ] Programme and key dates
- [ ] Procurement route and contractor list (where known)
- [ ] Design risk register from the design team

- [ ] Arrangements for managing the significant risks identified in PCI
- [ ] Site rules and induction process
- [ ] Traffic management plan
- [ ] Welfare provision (toilets, drying room, rest facility, drinking water)
- [ ] First aid and emergency arrangements
