Home Construction Contract Checklist Thailand: Review Before Signing

What to check in the contract

• Scope of work: list inclusions and exclusions in writing, such as earthworks, fencing, landscaping and off-house utilities.
• Drawings and specifications: attach architectural and engineering drawings and a materials/equipment spec list, with criteria for substitutions.
• Price and BOQ: attach the bill of quantities (BOQ) so it can be compared with the contract price.
• Payment stages: should match completed work stages; be cautious of an unusually high first payment.
• Schedule: start and handover dates, late-delivery penalties and extension conditions.
• Variations: require an approval and price agreement before work starts.
• Inspection and warranty: the period and what is and is not covered must be written into the contract.
• Building permit: confirm who applies to the local authority for the construction permit and who supervises the works.

For Greenery projects: more than 50 homes delivered, over 15 years of experience, and a 5-year main-structure warranty under the contract terms, covering only the items the contract specifies.
