The Construction Registers Service comprises the Register of Contractors and the Register of Projects which have been established in terms of the CIDB Act (Act 38 of 2000). The Register of Contractors grades and categorises contractors according to financial and works capability. It is mandatory for public sector clients to apply the Register of Contractors when considering construction works tenders. The Register of Contractors facilitates public sector procurement and serves as a framework for contractor development.The Register of Projects gathers information on the nature, value and distribution of projects. When clients register projects, the track records of contractors are updated and the information is available to other clients through the cidb website. Public sector clients are required to register projects above R200,000 while private sector clients and large state owned entities are required to register projects above R10 million. The cidb has also developed the i-Tender service which enables clients to advertise tenders on the cidb website. i-Tender automatically alerts registered contractors of tender opportunities by email and sms. Tenders are also displayed on the cidb Register of Projects website.
