In exceptional cases, Infrastructure South Africa (ISA) will review infrastructure investment projects and programmes below the R1 billion threshold if they are able to demonstrate that they hold a significant strategic contribution to South Africa’s short and long-term socio-economic development. These projects will need to demonstrate that they are in alignment with guiding development policy frameworks, such as the: National Development Plan (NDP), National Infrastructure Plan (NIP) 2050, Infrastructure Development Act (IDA), National Spatial Development Framework (NSDF), Economic Reconstruction and Recovery Plan (ERRP).

Infrastructure South Africa (ISA) does not provide grant funding, project funding or financing directly to Project Sponsors from either the private or public sectors. The mandate of ISA is to support Project Sponsors with project preparation, through the SIDS Methodology, to ensure that their projects reach the bankability stage.

Although Infrastructure South Africa (ISA) does not provide direct project funding, projects that are registered with ISA will go through the SIDS Methodology, utilising defined processes that support business case development, to ensure that they reach the bankability feasibility stage. These processes are dependent on project readiness, the complexity of the work that needs to be completed, as well as the proposed allocated time frames for each project. There is no set period for projects to reach bankable feasibility level. However, in terms of the infrastructure investments projects appraisal and approval process, as soon as a project is approved for registration with ISA, the Early Business Case must be concluded within 6 months.

The SIDS Methodology adopts the Five Case Model from the UK Infrastructure and Projects Authority (IPA); an internationally recognised best practice methodology for business case development. This methodology is recognised by both local and internal Development Finance Institutions (DFI) for infrastructure project preparation phase. Using this methodology, ISA seeks to establish the strategic fit, social and commercial viability of projects and programmes and offer support to Project Sponsors to develop their early, intermediate, and final business cases in line with best practice standards.

Information about the SIDS Methodology is available directly on the ISA website. Click here

The SIDS Methodology provides guidance for project sponsors or developers to take their projects from concept phase to achieving bankable feasibility. Support is offered to project sponsors to develop their early, intermediate, and final business cases to ensure that projects are strategically aligned, economically and socially desirable, commercially viable, affordable, and implementable. The process is designed with the requirements by the National Treasury in terms of funding for capital projects via the Budget Facility for Infrastructure (BFI) and the Public Private Partnership (PPP) process. In addition the methodology aligns with the requirements for funding of capital projects by the Infrastructure Fund (those projects that qualify for blended finance).

The following benefits are achievable for sponsors or developers:

  • There is a defined process or roadmap to take projects from concept to bankable feasibility studies, which is an internationally recognised process that aligns with the requirements by the National Treasury, Infrastructure Fund, as well as local and international DFIs.
  • Projects can obtain visibility to investors through the SOURCE system, which is accessed by infrastructure projects funding and financing institutions.
  • Infrastructure South Africa (ISA) provides support to private sector infrastructure projects in terms of unblocking and navigating processes in government to unlock infrastructure investments.

Infrastructure South Africa (ISA) focuses on both economic and social infrastructure projects and programmes. These projects and programmes must have a project value of R1 billion and above.

  • Unblocking support on projects especially within the regulation and permitting phase in line with the provisions of the Infrastructure Development Act.
  • ISA provides project preparation support.

Infrastructure South Africa (ISA) accesses technical support from the Technical Advisory Panel as well as resources in the form of secondees from the private sector. ISA also works closely with local and international funding and financing institutions that provide project preparation support. ISA also leverages the technical capacity of the Infrastructure Fund for this purpose. This is in addition to the internal capacity of the team to support project sponsors on project preparation.

When an infrastructure investment project is registered with Infrastructure South Africa (ISA) and complies with the registration criteria, it is submitted for approval to the Infrastructure Investment Review Committee (IIRC) and a decision by the IIRC is communicated within a month to the project owner. As the project moves from Early Business Case, to Intermediate Business Case and Final Business Case, ISA remains in close contact with project owners and sponsors throughout the process.

  1. The Project Sponsor completes the registration form. 
  2. Projects then go through a registration process.
  3. ISA has a Portfolio Management Office which, inter alia, ensures that the registration requirements are complied with and submits the application to the Infrastructure Investment Review Committee (IIRC) for approval. 
  4. An Early Business Case is developed and submitted to the IIRC for approval.
  5. The Intermediate Business Case is developed and submitted to the IIRC for approval
  6. When the IBC is approved by the IIRC, it is submitted to the National Treasury, DFIs and other funding and financing institutions for funding decisions to be made.
  7. When the funding decisions are made, Infrastructure South Africa submits the project or programme to the PICC Council and/or Cabinet to approve the project as a Strategic Integrated Project.
  8. Following Cabinet’s approval, the Minister of Public Works and Infrastructure gazettes projects as SIPs, as per the provisions of the Infrastructure Development Act.

The Infrastructure Development Act (IDA) 23 of 2014 is a key guiding policy framework for infrastructure development in South Africa. The aim of the IDA is to:

  • Provide for the facilitation and co-ordination of public infrastructure development which is of significant economic or social importance to the Republic.
  • Ensure that infrastructure development in the Republic is given priority in planning, approval, and implementation. Schedule 2 of the Act allows for a shorter period for the regulation and permitting of projects.
  • Ensure that the development goals of the State are promoted through infrastructure development.
  • Improve the management of strategic infrastructure during all life-cycle phases, including planning, approval, implementation, and operations.
The Infrastructure Development Act provides for unblocking and acceleration of both public and private sector infrastructure projects. ISA coordinates with regulatory agencies, public entities, national and provincial governments as well as municipalities to unblock government processes that may impede infrastructure investments. The actual method of work undertaken by ISA is determined by the type of projects and the requirements to unblock the projects. ISA works within the defined regulatory, policy and relevant statutes of government.
The Infrastructure Fund (IF) is managed by Infrastructure South Africa (ISA) and operationalized by the DBSA through a “ring-fenced” division of the bank. A Memorandum of Agreement was signed in August 2020 between National Treasury, DBSA and ISA. As part of the Infrastructure Fund value chain, Infrastructure South Africa has a mandate to develop and manage the IF pipeline. It should be appreciated that infrastructure projects can be identified from a variety of sources, including from Government, public entities, ISA, private sector and civil society. However, all potential programmes and projects will require ISA approval before they are formally admitted to the IF project pipeline.
