Why terms matter
Pricing terms affect what is included, provisional and risky.
Common groups
Most terms relate to measured work, allowances, tendering, variations, cost planning and commercial review.
Use the glossary beside the quote
Shared definitions help clients, architects and builders review the quote on the same basis.
Use a controlled vocabulary
Choose one term for each commercial concept and use it consistently across the estimate, tender comparison and client pack. If the contract documents define a term differently, follow the project definition and make that clear.
Resolve ambiguous wording
Words such as allowance, estimate and provisional can carry different meanings. When the commercial effect matters, add the amount, scope covered, adjustment method and person responsible for confirmation.
Review checklist
- Define terms at first use
- Use the same wording in every project output
- Link allowances to a clear scope
- Check project-specific contract definitions
