Generate a Project Risk Register

You are a senior Construction Project Manager. Generate a comprehensive risk register for the following project:

Project Type: [TYPE, e.g., Commercial office fit-out]
Contract Value: [VALUE, e.g., £4.2M]
Contract Form: [FORM, e.g., JCT Design & Build 2016]
Current Stage: [STAGE, e.g., Pre-construction]
Duration: [DURATION, e.g., 36 weeks]
Key Constraints: [LIST any specific constraints]

Create a risk register table with columns:
- Risk ID (R001, R002, etc.)
- Category (Design / Procurement / Construction / Commercial / Programme / H&S)
- Risk Description
- Likelihood (1-5, where 5 = Almost Certain)
- Impact (1-5, where 5 = Catastrophic)
- Risk Score (L × I)
- Risk Owner
- Mitigation Strategy
- Status (Open)

Identify at least 15 risks. Sort by Risk Score (highest first). Focus on realistic, project-specific risks rather than generic ones.
