What is a Building Contract?
The Building Contract is a fundamental document for construction projects in Switzerland, structured in accordance with the Swiss Code of Obligations (Articles 363-379) and incorporating SIA standards, particularly SIA 118. This agreement is essential when a property owner (employer) engages a contractor to undertake construction works, whether for new buildings, renovations, or major modifications. It comprehensively addresses all aspects of the construction project, from technical specifications to legal obligations, while ensuring compliance with Swiss federal and cantonal building regulations. The document is particularly important as it provides legal certainty and clear allocation of risks and responsibilities, incorporating specific Swiss construction industry practices and requirements. It should be used whenever engaging in significant construction works in Switzerland, as it provides the necessary framework for project execution while protecting the interests of all parties involved.

A Building Contract is your primary legal document for any construction project in Switzerland, establishing the binding relationship between you as the property owner and your chosen contractor. This comprehensive agreement governs everything from project specifications to payment terms, ensuring your construction work complies with Swiss law and industry standards.
When do you need this document?

Additionally, banks and insurance providers typically require a formal building contract before approving construction financing or providing project insurance coverage.
Key legal considerations
Your Building Contract must address several critical legal elements under Swiss law. The scope of works section should detail exact specifications, materials, and quality standards to prevent disputes over deliverables. Payment terms must comply with Swiss payment practices, typically including advance payments, progress payments tied to completion milestones, and retention amounts. You should include comprehensive warranty provisions covering both defects liability periods and guarantee obligations as required under the Swiss Code of Obligations. Risk allocation clauses are crucial, particularly regarding weather delays, ground conditions, and variations to the original scope. The contract should also specify dispute resolution mechanisms, with many Swiss construction contracts incorporating SIA arbitration procedures for efficient conflict resolution.
