Only 65% of projects experienced a cost increase during their construction, though a mean rework cost of 0.39% of the contracted value was incurred, which had a negative impact on the contractor’s overall margin. In addition, the difference between approved client change-orders and those by the contractor for subcontractors was 0.5% of the total costs incurred for the sampled projects, which had an adverse impact on the organisation’s profit. The upshot here is that the contracting organisation underwent a mean loss in profit of 23% per annum over the period of analysis. It is suggested that margin losses might well have been higher as rework was seldom formally documented and reported.
