Infrastructure South Africa (ISA) hosted the Sustainable Infrastructure Development Symposium South Africa (SIDSSA) 2025 between 25 and 27 May in Century City, Cape Town. The SIDSSA is a pioneering event aimed at bringing together key stakeholders, experts, and decision-makers in the field of infrastructure development.
The Keynote address at the Symposium was delivered by H.E President Cyril Ramaphosa on 27 May 2025. The symposium was anchored by the Minister of Public Works and Infrastructure, Mr. Dean Macpherson and various other Ministers and Deputy Ministers who led numerous panel discussions and technical discussions throughout the Symposium.
During the symposium, Infrastructure South Africa launched the second edition of the Construction Book, featuring over 250 projects valued at more than R268-billion – nearly double the value of the previous edition.
In addition, the top seven catalytic projects were announced for project preparation support, benefiting from a first-of-its-kind R600-million funding allocation to accelerate their implementation.
Team Gauteng at SIDSSA 2025
The Gauteng Provincial Government, led by Premier Panyaza Lesufi, showcased a bold portfolio of bankable, transformative infrastructure projects at SIDSSA 2025.
As a strategic partner of the Summit, Team Gauteng participated under the theme: “Delivering Catalytic, Scalable Infrastructure for Inclusive Growth.”
Gauteng used the platform to demonstrate how infrastructure development is central to unlocking economic potential, creating jobs, and enabling the Just Transition, while accelerating the implementation of the Gauteng Infrastructure Masterplan and the South African Economic Reconstruction and Recovery Plan (ERRP).

The Gauteng Provincial Lounge at SIDSSA 2025
The Gauteng Lounge, a collaborative space hosted by the GGDA, featured participation from the Gauteng Department of Economic Development (GDED), Gauteng Department of Infrastructure and Cooperative Governance (GDID) and Gauteng Infrastructure Financing Agency (GIFA).
Attendees were able to explore projects such as:
- The City of Johannesburg’s Waste-to-Energy Programme – a flagship 88MW project that exemplifies climate-smart innovation, converting landfill gas into clean power and job opportunities in the circular economy.
- The OR Tambo SEZ – Precinct 2 expansion – located near Africa’s busiest air cargo terminal, this project supports advanced manufacturing in pharmaceuticals, electronics, and agro-processing, backed by strong logistics infrastructure.
- The Lanseria Smart City, South Africa’s first post-apartheid smart city development, designed for green living, AI-driven planning, and urban resilience.
The Lounge also offered access to the full Gauteng Infrastructure Investment Booklet, which features over R230-billion in investment-ready opportunities in the water, transport, energy, housing, and industrial development sectors.
G20 Dialogue on Fiscal Policy
Speaking at the UK G20 Dialogue on Fiscal Policy, Mr. Saki Zamxaka, Acting Group CEO of the GGDA unpacked the province’s approach to financing sustainable infrastructure, grounded in blended finance and institutional capacity.
From under-execution at a local level to designing projects that attract private capital, Mr. Zamxaka highlighted the realities and opportunities facing provincial governments.
It’s no longer just about funding — it’s about viability and delivery. Without capable municipalities, infrastructure won’t materialise, even with the best pipeline.
The panel also included Hon. Ashor Sarupen, Deputy Minister of Finance, South Africa and John Humphrey, His Majesty’s Trade Commissioner for Africa.
Gauteng remains committed to enabling bankable infrastructure, accelerating project implementation, and building investor confidence.
