LHDA calls for tenders for the construction of Polihali dam and appurtenant works
The Lesotho Highlands Development Authority (LHDA) has called for the submission of tenders for the construction of Polihali dam and appurtenant works under Phase 2 of the multibillion-rand bi-national Lesotho Highlands Water Project.
Interested and suitably qualified tenderers have until November 12, 2021, to submit their proposals.
The Polihali dam will be a 166-m-high basalt concrete face rockfill dam (CFRD) situated on the Senqu river near the town of Mokhotlong.
The reservoir capacity will be 2 325-million cubic metres and, apart from the main dam embankment, the project includes a 43-m-high saddle dam, also CFRD; a 33-m-high upstream cofferdam; 105-m-high intake tower with a 5 m outlet tunnel/chute to release 300 m3/s; a 98-m-long ogee spillway designed to discharge 4 300 m3/s; two bridges and an outlet house incorporating compensation and flood release valves, as well as a 2 x 2.1 MW mini hydropower station.
Tender documents will be available for download or collection from the LHDA from August 9.
A virtual pre-tender meeting will be held on August 23, with a site visit scheduled on August 31.
