The guarantee of completeness in construction law: admissibility, scope, practical implications
Guarantees of completeness are key instruments for the allocation of risk in construction contracts. The contractor is required to perform all services necessary to achieve the contract’s objectives – even if they are not expressly mentioned in the specifications. But when is this transfer of risk effective, and where do public policy, the duty to warn and the sphere theory draw clear boundaries?
Hon. Prof. Dr Irene Welser will address these questions in her lecture ‘On the Admissibility of Guarantees of Completeness’ at the Austrian Construction Law Forum.
The focus is on:
- Distinction: Declaration of inspection/knowledge versus genuine assumption of risk
- Contract models and specifications: functional, constructive, hybrid forms; lump-sum and unit prices
- Limits of admissibility
- Practical guidelines for effective clauses
