Request for Proposals (RFP) for the provision of services on the Wind Tunnels Legacy System. The purpose of the Request for Proposal (RFP) is to obtain capability, pricing and general information on the business of potential Contractors for the CSIR to determine the Contractors most capable of providing the service. CSIR has endeavoured to upgrade the computing hardware, software and general machinery to modern systems, affordability and other constraints have resulted in remaining operational “legacy” systems. “Legacy” systems are considered systems that have not been upgraded since the inception of the facilities but maintained in operational conditions to date, through preventative and corrective maintenance and for which there is no further official commercial or technical support. These systems may date back to the 70’s but mostly mid 80’s. Preventative and corrective maintenance services as well as other operational support for these systems are required by the CSIR Defence and Security’s Aeronautic Systems Impact Area.
