This episode unpacks the critical role of architect’s instructions in construction contracts. We discuss what constitutes a valid instruction, the authority of the architect to issue changes, and the legal and procedural requirements surrounding such instructions. The episode also examines scenarios where contractors may challenge or refuse instructions, the implications of non-compliance, and the process for issuing variations that impact cost and schedule. Through real-world examples and key case studies, we shed light on best practices for managing and documenting architect's instructions to minimize disputes and ensure project alignment.
