- Description
- A considerable amount of research has examined the cost performance of construction projects, yet there has been a paucity of studies that have examined the impact that client initiated change-orders and rework have on contractors. This paper seeks to add further clarity to this issue by replicating previous empirically-based research to establish the validity and reliability of the key issues influencing a contractor's cost performance. A total of 98 projects were used to examine the value of rework and change-orders and their influence on a contractor's margin. Only 65% of projects experienced a cost increase, though a mean rework cost of 0.39% of the contracted value was incurred. The difference between approved client change-orders and those by the contractor for subcontractors was 0.5% of the total costs incurred, which adversely impacted the organisation's profit. Margin losses may well have been higher as rework is seldom formally documented and reported.
