Research Context: Source edition/date: 2024/2025 edition. Research reviewed on 2 November 2026.
Two construction quotes can describe the same project name while including different work. Site preparation, finishes, approvals, protection of existing areas and disposal arrangements often explain a large part of the gap.
Understand the Research Context
UNEP’s 2024/2025 Buildings and Construction report examines the sector’s sustainability transition. A global report does not certify a building, material or contractor. Read the UNEP: Global Status Report for Buildings and Construction 2024/2025 for the original context. The practical questions below are Best10Companies editorial analysis, not the source organization’s checklist or an endorsement.
What to Ask Before You Commit
Use an agreed scope, drawings and schedule when requesting proposals. Ask each contractor to identify quantities, assumptions, exclusions and provisional items. Discuss change approval and how progress will be recorded. Important engineering, safety and contractual decisions should be reviewed by qualified professionals rather than inferred from the appearance of a quotation.
| Check | Evidence to Request |
|---|---|
| Common scope | Drawings, specification and quantities |
| Price boundaries | Exclusions and provisional items |
| Changes | Approval, evidence and effect on time or cost |
A Practical Exercise
Choose one room or work package and trace it from existing condition to accepted finish. The activities between those points are useful checks against both proposals.
Build a Clearer Shortlist
Use the same brief when you compare companies offering Construction & Property services. Keep the answers, assumptions and exclusions together so that a later decision is based on comparable information. When you are ready to post your requirement, describe the scope and the evidence you need rather than requesting a general promise of results.
