LHWP to launch prequalification for Phase II works in January 2019

The prequalification for the construction of the Phase II main works, the Polihali dam and Polihali transfer tunnel, is commencing in January.

Lesotho Highlands Water Project (LHWP) will start 2019 with the launch in January of the construction pre-qualification for the Phase II main works, the Polihali dam and Polihali transfer tunnel. 

“The call for Expressions of Interest for the construction of the 165 m-high Polihali dam and the 38 km-long Polihali transfer tunnel is expected to attract the interest of major engineering and construction companies, and we encourage suitably experienced contractors to join forces with local contractors and apply,” Tente Tente, Phase II Divisional Manager, confirmed yesterday.

The prequalification documents will include requirements for participation by Lesotho- and South Africa-national contractors, in accordance with the terms of the Phase II Agreement and the project’s commitment to ensuring local participation. It will be advertised on the LHDA website at http://www.lhda.org.ls/phase2/tenderbulletin/ and in local print media.

“Implementing large scale infrastructure projects combines ‘maths and music’:  the maths of delivering multiple highly technical engineering components within a specific timeframe and budget, and the ‘music’ of the softer skills of diplomacy, communication, social, environmental and community protection, while considering the interests and expectations of multiple, diverse stakeholders. Phase II of the Lesotho Highlands Water Project is no exception to this and while the project is behind the timelines proposed in the feasibility report, given the two-year deferred start, Phase II is moving ahead purposefully, with 2018 having been a busy year for the both the water transfer and hydropower components,” added Mr Tente.

In summary, more than 35 contracts are in force covering a range of environmental impact assessments, socio-economic and resettlement projects, hydropower feasibility, advance infrastructure projects encompassing access roads, project housing, power and telecommunications, geotechnical investigations, the Polihali diversion tunnel, major bridges and the main works including the Polihali dam and transfer tunnel. Other than the geotechnical drillers, demarcation survey and the first two advance infrastructure construction contract awards announced in the previous quarter, these are all consulting services contracts.

Phase II is moving ahead purposefully, with 2018 having been a busy year for the both the water transfer and hydropower components.

Resettlement planning is nearing completion; livelihood restoration demonstration projects have started in the project area. Environmental Records of Decision have been granted for the Polihali western access corridor and the main Polihali project area, environmental go-ahead has been given for the new Polihali western access road and the Polihali dam, Polihali transfer tunnel, major bridges and project housing. The fieldwork for the cultural heritage protection programme is progressing steadily. Equally importantly, the dam and tunnel designs are at an advanced stage and several more advance infrastructure construction contracts are under procurement.

The further feasibility studies for the hydropower component of Phase II are nearing completion. Conventional hydropower has been confirmed as the more feasible option to meet Lesotho’s energy needs. To this end, the decision was taken earlier this year to advance the studies for two sites on the Senqu river and advance one at Oxbow to bankable feasibility. These studies are expected to be completed by the second quarter of 2019.

A pumped-storage scheme option has been deferred as a result of the prevailing economic conditions.

“Advance infrastructure construction has started and is expected to be largely completed by 2020 before the dam and tunnel construction commences. In all, we’re confident that 2019 will see Phase II taking great strides with activities on the ground evident to all.”
