Abstract
Rework in construction contracts is an interesting topic as it influences contractual claims and disputes. Changes in design, scope, and construction turn into rework and then affect project completion time, performance, and contract sum. Addressing the rework provision in a well-defined contract before the work commences will safeguard the project against unforeseen circumstances Contractual rework provisions are difficult to trace as they are often written indirectly or in a complex context. Therefore, a list of rework causes from the literature is used in this study to investigate rework clauses and identify the relevant provisions in the general contract conditions. Rework provisions in the New Zealand standard contract are reviewed first and the identified contract clauses are then evaluated based on the result of the questionnaire survey and professional interviews. The mixed method, both quantitative and qualitative approach, is utilized for data collection and analysis. This research revealed that only five significant causes of rework, involved in the categories of process, materials and equipment, are adequately addressed in the contract conditions, so the remaining causes of rework require further investigation. The result also identified five contract clauses related to rework provisions. The study suggests the contract parties review the rework provisions ahead of time during the negotiation of the contract. This approach enables the parties to manage their obligations under rework events by addressing other causes of rework. Properly addressing the causes of rework in the contract provisions reduces contractual claims, disputes, and improves the overall project performance.
