The following returnable documents are mandatory: signed and completed SBD 1 (Procurement Invitation) including SBD 4, SBD 6.1, and the signed Bid Submission Certificate form; proof of authority (e.g., company resolution); proof of CSD registration; a valid B-BBEE certificate or sworn affidavit (for EMEs/QSEs) to claim preference points; completed pricing schedule (SBD 3.1) or quotation on company letterhead; product specifications or datasheets for proposed materials; confirmation of willingness to cut reinforcing rod sections into 0.5 m lengths. Bidders must also provide unit prices and total quotation, estimated delivery period, and warranty information where applicable.

Evaluation follows a staged process: Stage 1 – compliance with submission requirements; Stage 2 – evaluation against technical specifications, including quality and possible due diligence interviews or proof of delivery; Stage 3 – price/preference evaluation using the 80/20 preference point system (80 points for price, 20 points for specific goals); Stage 4 – tax compliance check; Stage 5 – award and contract signing. The lowest priced bid receives maximum points for price, with others ranked relative to it. Preference points are claimed via SBD 6.1 for B-BBEE status level, black-owned, black female-owned, black youth-owned, people with disabilities, and EME/QSE status. A valid B-BBEE certificate is required to earn specific goal points.

The scope is the supply and delivery of materials and equipment for constructing rain manipulation structures (rainout shelters) for a long-term drought experiment at Tierberg LTER in the semi-arid Karoo. The structures must provide partial rainfall exclusion and rainfall addition while withstanding long-term outdoor exposure. Delivery is to a shipping container at Renu-Karoo Nursery, 2 Van Dyk Street, Prince Albert, Western Cape, on a date agreed with NRF-SAEON. Materials must be suitable for permanent outdoor installation, new, unused, and free from defects. The full list of materials and quantities is specified in Table 1 of the document, including Y standards, timber, screws, roof sheets, gutters, pipes, concrete blocks, and various consumables. Suppliers must provide product specifications or datasheets for proposed materials and confirm willingness to cut reinforcing rod sections into 0.5 m lengths.

Pricing must be submitted on SBD 3.1 or a quotation on company letterhead. The price schedule is firm and inclusive of all costs, including delivery to the specified delivery point and VAT. The NRF requires firm quantities for the contract period, with delivery dates determined during the contract. Estimated quantities may be required for establishing the contract ceiling price. The NRF issues written purchase orders for actual quantities. Price adjustments are subject to special conditions and risk sharing. Prices must be quoted in South African Rands. The pricing schedule lists all 40 items with quantities and units, plus a line for delivery to Renu-Karoo Nursery. Total price excluding VAT, VAT, and total contract including VAT (ceiling price) must be provided.

The 80/20 preference point system applies. Price points are calculated using the formula Ps = 80(1 - Pt/Pmin), where Pt is the price of the tender under consideration and Pmin is the price of the lowest acceptable tender. Specific goals points are allocated as per Table 1 in SBD 6.1: B-BBEE status level contribution (levels 1-3: 8 points, 4-6: 6 points, 7-8: 2 points), supplier at least 51% black-owned (3 points), black female-owned (3 points), black youth-owned (1 point), owned by people with disabilities (1 point), and EME or QSE (4 points). A valid B-BBEE certificate is required to claim these points.
