Abstract

The delivery tunnel op phase 1A of the Lesotho Highlands water project extends 37km from the 'Muela reservoir in Lesotho to an outfall on the Ash/Axle River near Clarens in South Africa. The tunnel, for which tender design was carried out by one design consultant, was procured as two entirely separate detailed design and two separate construction contracts - the 15km southern section in Lesotho and the 22km northern contract in South Africa. Both contracts were completed successfully within time and budget. This paper introduces the overall tunnel project and then describes the work undertaken in each of the two separate design and construction contracts.
