Compare like with like
Before comparing figures, confirm proposals use the same plans, specifications, and quantities. A large difference may reflect a missing item or different material rather than real savings.
- A clear scope definition
- Materials, specifications, and allowances
- Exclusions and owner-supplied items
- Stages and linked payments
- How changes are priced and approved
Ask for assumptions to be explained
Anything unresolved at pricing should appear as an assumption or defined allowance, so its effect is clear when the final selection is made.
