5.2.6 Officials accompanying the delegation on the tour of the facilities complained that the leakages in Unit 4 had been there ever since the roof was 'repaired' by a DPW-appointed contractor. They were concerned about how maintenance-tenders were awarded, as often repairs are not up to standard, leading officials to believe that service providers were not equipped to handle the projects and that fronting, nepotism and favouritism corrupted the process. That only four contractors were attending to the entire region's needs was a major cause for concern. The DPW explained that contractors were registered and screened by the Contractor Development Board. Projects greater than R500 000 were advertised in an open tender, while those below R500 000 were attended to by contractors identified from the DPW's database. Risk assessments were done for bigger projects and regional offices submitted bids to the national office where necessary. The DPW emphasised that planned maintenance was its responsibility, while capital works was that of the DCS. Most of the work that needed to be done was of capital nature.
