Bombela, the consortium which is to build and operate the R25-billion Gautrain project, consists of international partners Bombardier, Bouygues Travaux Publics and RATP, and local stakeholder Murray & Roberts, along with empowerment company the SPG.
"SPG has ensured that its involvement is not only an equity level, but at all operational levels of the project," Diliza said on Friday.
The company said that its inaugural joint venture (JV) with diversified transportation distribution and logistics company, Unitrans, was enjoying success.
The venture, called Induna Tippers, is responsible for the transportation of the 2-million tons of material being excavated during the construction phase of the Gautrain project.
The Induna Tippers JV is 50,5% owned by SPG, with the remaining 49,5% owned by Unitrans.
The construction of the Gautrain will be completed in two phases – with the first phase to be completed in 45 months (in time for the 2010 FIFA World Cup), and the second phase to be completed in 54 months.
The first phase will involve the construction of a network between the OR Tambo International Airport and Sandton, north of Johannesburg.
The second phase will include the remainder of the rail network between Sandton and Johannesburg, including the route from Midrand to Hatfield.
The project is a public-private partnership beween Bombela and the Gauteng government, and will link Tshwane, Johannesburg, and the OR Tambo International Airport by 2011.
