What are the main types of construction contracts under Belgian law?

Belgian construction law recognizes several contract types including enterprise contracts, architect agreements, and subcontracting arrangements, each with specific legal frameworks.

Belgian construction law governs various contract types, each with distinct legal implications and requirements. The enterprise contract (ondernemingsovereenkomst) is the most common, where a contractor agrees to deliver a completed construction project for a fixed price or based on measurements.

Architect agreements fall under intellectual services contracts, establishing the architect's duties for design, supervision, and coordination. These contracts must clearly define scope, fees, and liability limitations.

Subcontracting agreements involve specialized work delegation, requiring careful attention to payment terms, liability distribution, and coordination responsibilities. The main contractor remains liable to the client while managing subcontractor relationships.

Management contracts and design-build agreements are increasingly popular, combining design and construction responsibilities under single entities. Each contract type has specific legal requirements regarding warranties, liability periods, and dispute resolution mechanisms.

Key considerations include the 10-year architect and contractor liability period, mandatory insurance requirements, and compliance with public procurement rules for government projects. Contract clauses must address payment schedules, variation orders, force majeure events, and termination procedures.
