Explanation of Unusual or Complicated Terms

  • 80/20 Procurement System: A preferential procurement framework governed by South African public procurement regulations. It reserves approximately 80% of contract opportunities for Small, Medium and Micro Enterprises (SMMEs) and Historically Disadvantaged Individuals (HDIs), while allocating 20% to other qualified entities. This mechanism promotes economic transformation and market access for previously marginalised groups.
  • Sealing Bladder: A flexible, pressure-rated elastomeric membrane used in hydraulic accumulators or isolation systems. It expands and contracts to store energy, absorb shock, or maintain system pressure without direct fluid contact with mechanical components.
  • Safety Valve: A critical pressure-relief device engineered to automatically vent excess pressure from a closed system when predefined thresholds are exceeded, preventing equipment rupture, leaks, or hazardous failures.
  • Adaptor Hose Assembly: A pre-fabricated flexible conduit fitted with specialised couplings or threaded fittings on each end. It is designed to bridge mismatched pipe diameters, thread types, or connection standards, enabling rapid installation and maintenance flexibility.
  • Informal Tender: A streamlined procurement process utilised for lower-value purchases. It features simplified documentation, faster evaluation timelines, and reduced administrative overhead compared to formal competitive tenders, while still maintaining transparency and fairness standards.

Joint Ventures, Consortia and Subcontracting:

Most large tenders are composed of tasks in a number of different fields, and it is not always possible for a single company to cater for all of them, and therefore Joint Ventures and Consortia are formed to then submit a tender together.

Government tenders are also requiring the subcontracting of a percentage of the tender work, and the trouble is then finding Subcontractors to comply with the tender requirements

To assist companies with finding tender partners and subcontractors, you can now submit your contact details and company information on this page, so other interested parties can contact you for purposes of forming Joint Ventures and subcontracting
