Leading consulting engineering and infrastructure advisory practice, Zutari is continuing its involvement with the world-leading MeerKAT radio telescope array, where it has played a leading role since the project first broke ground.
“Zutari has been involved with this initiative for about 15 years. It is one of our flagship projects, and very close to our hearts. We are very proud and privileged to be a part of such an exciting global venture,” said major projects director, Jana Jooste. “What makes our ongoing involvement unique is that, whereas we previously only designed the infrastructure for MeerKAT, our current appointment is as a professional services consultant for the client. It means we are embedded in the client’s team, a testament to the incredible collaboration we have as part of a global professional team on this flagship international project.”
The main client is the Square Kilometer Array Observatory (SKAO), based in the United Kingdom. Zutari’s current role is to guide the infrastructure construction contractors through the designs and subsequent construction work. “The local design and construction activities need to be closely aligned with other work packages being developed, specifically the telescopes being developed in China. Where this becomes interesting and challenging is coordinating all these global efforts to find ways, tools and mechanisms to make sure that ultimately there is a single integrated telescope array,” explains Jooste. “We regularly sit in on meetings with the other design teams based all over the world. Zutari is also developing power solutions for the site. Hence, there is an international flavour to what ultimately will be a South African solution on the ground here in the Northern Cape.”
Zutari’s longstanding involvement with the project extended to assisting the National Research Foundation (NRF) with the necessary technical support to ensure South Africa could demonstrate that it had the capability to host the telescope. The telescope is operated by the South African Radio Astronomy Observatory (SARAO), a NRF facility.
The 64-dish MeerKAT is the largest radio telescope in the southern Hemisphere, and one of two SKA precursor instruments based in South Africa. Located in the Karoo semi-desert, it was expanded with an additional 24 dishes under the MeerKAT+ project. This was jointly funded in 2019 by SARAO and the Max-Planck-Gesellschaft of Germany, and since 2020 by the Istituto Nazionale di Astrofisica. The telescope will later be gradually integrated into the Square Kilometre Array Mid-frequency telescope (SKA-Mid).
The SKA Observatory (SKAO) is an intergovernmental organisation bringing together worldwide expertise to build and operate cutting-edge radio telescopes, to transform our understanding of the universe and deliver benefits to society through global collaboration and innovation.
The SKAO has a global footprint consisting of its global headquarters in the UK, the two telescopes at radio-quiet sites in South Africa and Australia, and associated facilities to support the operation of the telescopes. Once fully operational, the SKAO will be a single global observatory operating two telescopes across three continents, on behalf of its member states and partners.
Local community engagement is a high priority for the SKAO. “The telescope will be operating for an extended period of time, and the buy-in and benefits to the local community are a major focus area.” Initiatives have been implemented to benefit and upskill local companies and entrepreneurs, from providing physical labour, local contractors and suppliers, to related soft services. “We are looking at the entire region both during construction and post-construction when the telescope is operational,” says Jooste.
Another benefit for the South African economy is the anticipated construction of a data centre and operations centre based in Cape Town, which will attract international researchers.
Zutari’s involvement with the project has garnered it major local accolades. It won the project category from R50 million to R250 million at the 2023 CESA Aon Engineering Excellence Awards. It subsequently received a commendation for Most Outstanding Civil Project (Technical Excellence) at the 2023 SANRAL SAICE National Awards. The project was also declared a winner in the Consulting Engineers category at the Construction World Best Project Awards last year.
“We are proud to have provided the critical base infrastructure needed for these SKA dishes to operate effectively,” says Dr Gabi Wojtowitz, who oversaw the foundation and geotechnical work. Zutari conducted preliminary and detailed design, verification, and construction monitoring for the 24 dish foundations for MeerKAT+, and also the power and fibre needed to collect and relay data over vast distances. The project included the complete design verification and design of the access and foundation elements for the remaining 109 dish positions for the SKA-Mid array.
