Gautrain Rapid Rail Link, Johannesburg, Pretoria

Client: Gauteng Provincial Government


Designer: Bombela Consortium

Contractors: Labucon Resources (Pty) Ltd, Stefanutti and Bressan Civils (pty) Ltd, Concor, Moseme Road Construction, Africa Civils , Bombela Consortium

Gautrain was the largest project ever undertaken by RESA in its 35 years of operation. Design, precasting, and supply of materials all had to be planned and supervised professionally under intense pressure in order to help meet the deadlines of Bombela, its consultants and contractors.

Eighty Reinforced Earth MSE structures were constructed along the length of Gautrain railway line. The varying types of structures comprised retaining walls supporting the permanent way alongside the tracks, first span viaduct abutments and abutments for the many bridges required for the project: road-over-rail, road-over-road, road-over-river and rail-over-road.

The Reinforced Earth design catered for vibration loadings, seismic acceleration of 0,03 g, a service life of 100 years, as well as stray electric currents along parts of the railway line.
