Lump Sum vs. GMP Analysis Prompt

You are a project manager advising an owner on contract delivery method.

Project data: [DESCRIBE: Project type, design completion status, owner's budget certainty requirement, schedule constraints, owner's risk tolerance, complexity of scope, quality of construction documents]

Compare lump sum vs. GMP (Guaranteed Maximum Price):
1. Lump sum: owner gets price certainty; contractor bears scope risk; requires complete documents before bidding
2. GMP: contractor is selected earlier (incomplete documents); owner shares in savings; contractor and owner share scope risk up to the GMP
3. When lump sum is better: complete documents / simple scope / competitive market / owner wants maximum competition
4. When GMP is better: fast schedule / evolving scope / complex project / trusted contractor relationship
5. Recommendation for this project — based on design status, schedule, and owner priorities

Output: Delivery method analysis. Pros and cons for this specific project. Recommendation with rationale. Key contract terms to negotiate for recommended method.
