SKA Infrastructure Construction Opportunities Market Survey


The Square Kilometre Array (SKA) radio telescope is a multinational project to deliver the largest, and one of the most technologically advanced, radio astronomy facilities in the world. In 2012, South Africa, along with eight African Partner Countries, was awarded the right to host the mid-frequency component of the SKA – known as SKA_MID.

The SKA Observatory, with its global headquarters located in Manchester (United Kingdom), was established as an inter-governmental treaty organisation responsible for the funding, construction and operation of the SKA telescope.

The SKA telescope will be delivered in a phased manner, with the first phase in South Africa referred to as SKA1_MID. For further information, go to

This artist’s rendition of the SKA-MID dishes in Africa shows how they may eventually look when completed. The 15m wide dish telescopes, will provide the SKA with some of its highest resolution imaging capability, working towards the upper range of radio frequencies which the SKA will cover.

Note: This Market Survey does NOT constitute the initiation of any procurement process, which is due to be undertaken at a later date by the SKA Observatory. Procurement opportunities made available by the SKA Observatory shall be conducted in terms of approved SKA Observatory procurement policies and procedures.

These opportunities are NOT issued by SARAO, nor shall they be conducted in terms of the Public Finance Management Act and associated national regulations such as the Preferential Procurement Regulations 2017 (PPPFA).

Local (Karoo) Opportunities

In respect of Contract 1, lead contractors will be required to sub-contract up to 30% of the value of the contracts, excluding major equipment and materials, to Exempted Micro Enterprises (EMEs) and Qualifying Small business Enterprises (QSEs) resident within 150km of the project site (primarily Carnarvon, Williston, Brandvlei and Van Wyksvlei Local Municipalities). Should no suitable local enterprises be available, opportunities will be extended across the Northern Cape Province. Similar conditions are in place for Contract 2, with no minimum percentage applied due to the highly specialised nature of the works.

These opportunities shall be facilitated by the lead contractors only AFTER the award of the main contracts by the SKA Observatory.
