2.9 Tender Evaluation Strategy
2.9.1 Technical Evaluation Threshold
Mandatory Technical Evaluation Criteria (gatekeepers) are ‘must meet’ criteria. These criteria shall not be
weighted, or point scored but shall be assessed on a Yes/No basis as to whether the criteria are met
unless set otherwise. An assessment of ‘No’ against any criterion shall technically disqualify the tenderer
and shall not be further evaluated against Qualitative Criteria.
Qualitative Technical Evaluation Criteria are weighted evaluation criteria used to identify the highest
technically ranked tenderer after determining that all the Mandatory Evaluation Criteria have been met.
The Qualitative Evaluation Criteria are weighted to reflect the relevant importance of each criterion. The
minimum weighted final score (threshold) required for a tender to be considered from a technical
perspective is 70%.
Evaluation will be done according to Tender Engineering Evaluation Procedure 240-48929482
