Description:
The SARAO RFI team is responsible for the testing of all internal Radio Frequency Interference (RFI) sources on the Karoo site for the current telescopes on site, such as MeerKAT and also for future expansions (so called MK+), and new telescopes such as the SKA (Square Kilometre Array). Given the number of items, physical size of the items and the increase in site equipment that needs qualification testing or re-testing, RFI test facilities additional to the small inhouse reverb chamber currently used by SARAO, is required.

This tender is for the Construction of an RFI Measurement Facility, with a reverberation chamber to be located at the SKA Klerefontein Support Base in the Karoo, Northern Cape.

The Measurement facility will be housed in a modular building until the SKA Engineering Operations Centre (EoC) is constructed and it will then be moved to the EoC.

The major part of the work for this contract is the supply and construction of a screened RFI chamber and as such the contractor supplying this will be the main contractor. The supply of a commercial off the shelf modular building, the foundations for the building and the electrical connections to the available power at the site can be subcontracted.

This main contract includes the supply, installation, qualification and commissioning of the RFI test facility, but excludes the supply of RFI test equipment (to be supplied by SARAO) that will be used when operating the chamber.
