4.1 Maintenance and Facilities 4.1.1 As mentioned above and in the Committee's May 2010 oversight report, poor maintenance and infrastructural weaknesses compromise security as well as the humane detention of sentenced and unsentenced offenders. The Committee, aware of the complexities inherent in the DCS' relationship with the DPW, nevertheless emphasises its dissatisfaction with the delay in the finalisation of the long overdue DCS-DPW SLA. The SLA is a blueprint for how resources will be spent in order to maintain assets such as buildings and equipment for example. The absence of such an SLA and maintenance plans for each centre, reflects poor management nationally, which in turn is echoed at centre-level. In addition to ensuring those maintenance needs that fall within its scope are addressed immediately, the DCS, because it is charged with the safe and humane detention of inmates, must ensure that serious maintenance issues are reported immediately, and that the necessary pressure is applied to ensure their speedy resolution. The National Commissioner must, by 28 February 2011, provide the Committee with the DCS' assessment of the draft SLA, clear timeframes for when any negotiations to amend it will be finalised as well as an indication of when the SLA will be signed.
