Why PPP committee rejected proposal for Nairobi-Mombasa Expressway
The PPP committee, in collaboration with the National Treasury, reviewed the proposal and the PDP report.
The committee found that the proposal does not meet the relevant criteria and should be abandoned in accordance with Section 43(11)(c) of the PPP Act, 2021.
"The committee directed that the Contracting Authority consider restructuring the Project to meet the evaluation criteria through expansion of the existing A8 highway," read the committee recommendation in part, as seen the public notice on My Government newspaper on Tuesday, August 12.
The committee recommended the resubmission of the proposal for a fresh determination in line with Section 43(12) of the PPP Act.
