Infrastructure South Africa


The INFRA SA Consortium is responsible for the design of the Infrastructure & Power Sub-elements for SKA1-mid in South Africa. This includes Access (roads, civil works), Buildings, Communication, Site Monitoring, Security, Antenna Foundations, Vehicles, Power, Water and Sanitation.

The Consortium held a detail design walkthrough in South Africa from the 4-7 December 2017, the objective of which was to review general design progress, confirm that the design solutions are correct and to identify any gaps / issues prior to the CDR submission. These objectives were achieved and paved the way for the finalization of documentation to the European Commission at the end of January 2018.

IN-SKA (SKAO, INAU and INSA) presented our deliverables to the European Commission in Brussels on the 14th March 2018.

The Consortium submitted its CDR Readiness Review Note to the SKAO on the 19th March 2018. All CDR documentation was submitted to the SKAO at the end of April 2018. The CDR is scheduled to take place in Manchester from the 2-4 July 2018.

The power and optic fibre cabling has arrived on site and work will now be underway to install these cables at the SKA1-mid Antenna Foundation prototype.

The ECP to effect changes to the SKA1-mid Physical Configuration has been approved by the SKAO CCB. These changes were a result of changes to powerline routing following the line route survey that was undertaken on site.

The geotechnical and geohydrological investigations have been completed and the final reports received by SARAO. These are being used as inputs to the construction licenses required for the SKA.

The INFRA SA Health & Safety Specification and Safety in Design (hazard analysis) has been finalised. Work is now underway to finalize the Power Ramp-Up Plan for SKA1-mid.

The Consortium submitted its updated Cost Plan to the SKAO in March 2018. Capital costs have increased slightly due to increase in material costs and RFI compliance.
