Supply of tga and dsc crucibles to the national metrology institute of south africa

The procurement is for thermogravimetric analysis (TGA) crucibles and differential scanning calorimetry (DSC) crucibles. The available document is the SBD 6.1 preference points claim form and does not contain further scope details.

Returnable documents:

• SBD 6.1 (Preference Points Claim Form): must be completed and signed to claim B-BBEE preference points. It requires company details (name, VAT number, registration number), type of company, principal business activities, classification, years in business, and B-BBEE status level claimed.
• Proof of B-BBEE status level of contributor: a valid certificate, sworn affidavit, or other prescribed proof must accompany the bid to claim points.
• Sub-contracting details: if any portion will be sub-contracted, indicate percentage, sub-contractor name, B-BBEE status, and whether the sub-contractor is an EME or QSE, and if it falls under a designated group.

Disqualification risks:

• Failure to submit proof of B-BBEE status level means no preference points are claimed.
• False or fraudulent B-BBEE claims may lead to disqualification, contract cancellation, recovery of costs, restriction from state business for up to 10 years, or criminal prosecution.

Evaluation is based on price and B-BBEE status level of contributor, using either the 80/20 or 90/10 preference point system.

• 80/20 system applies to bids with a Rand value up to R50 000 000 (all taxes included).
• 90/10 system applies to bids with a Rand value above R50 000 000 (all taxes included).
• Maximum total points for price and B-BBEE combined is 100.
• Price points: maximum 80 (80/20 system) or 90 (90/10 system), calculated using the formula Ps = 80(1 - (Pt - Pmin)/Pmin) or Ps = 90(1 - (Pt - Pmin)/Pmin), where Pt is the price of the bid under consideration and Pmin is the price of the lowest acceptable bid.
• B-BBEE points: awarded according to the status level table:
• Level 1: 20 points (80/20) or 10 points (90/10)
• Level 2: 18 or 9
• Level 3: 14 or 6
• Level 4: 12 or 5
• Level 5: 8 or 4
• Level 6: 6 or 3
• Level 7: 4 or 2
• Level 8: 2 or 1
• Non-compliant: 0 points
• The purchaser may require substantiation of any preference claim before or after adjudication.

The tender is for the supply of thermogravimetric analysis (TGA) crucibles and differential scanning calorimetry (DSC) crucibles. No further technical specifications are provided in the available document.

B-BBEE requirements:

• Bidders must submit proof of B-BBEE status level of contributor to claim preference points.
• Proof may be a B-BBEE status level certificate issued by an authorised body, a sworn affidavit as prescribed by the B-BBEE Codes of Good Practice, or any other requirement prescribed in terms of the B-BBEE Act.
• The applicable preference point system (80/20 or 90/10) depends on the estimated Rand value of the bid.
• Bidders must complete the SBD 6.1 form and declare any sub-contracting arrangements.
• No minimum B-BBEE level is specified as a pre-qualification; points are awarded based on the status level claimed.

Evaluation is based on price and B-BBEE status level of contributor. The 80/20 system applies for bids up to R50 million, and the 90/10 system for bids above R50 million. Price points are calculated using the specified formula. B-BBEE points are awarded per the status level table (Level 1 to 8, non-compliant). Total points for price and B-BBEE must not exceed 100.

The National Metrology Institute of South Africa (NMISA), Section: Organic Analysis, requires two TGA crucibles and two DSC crucibles as specified.
