The tender estimate for the construction of the Special Youth Care Centre in the Eastern Cape was not properly prepared and calculated by the quantity surveyor. The estimate of R173, 8 million was 33% below the contract amount of R231 million. According to an analysis of the tender report compiled by the implementing agent, the reasons for the increase in costs include the conservative pricing estimates. Future cost increases were not considered and operational costs, such as provision of accommodation for supervision personnel and transport of materials and equipment were not taken into account.
