CONSTRUCTION UPDATE – 28 February 2011

Posted on Mar 9, 2011 in Construction Update – 2011, Featured

A) CONSTRUCTION

On 8 June 2010, Phase 1 of the Gautrain System was opened for commercial service. The first phase operations include the airport train service between Sandton Station and OR Tambo International Airport, a commuter service between Sandton and Rhodesfield – with an intermediate stop at Marlboro Station – as well as dedicated feeder and distribution bus services to and from the Sandton and Rhodesfield Stations. The Operations Control Centre, together with the Train and Bus Depot facilities located just south of Allandale Road in the Midrand area, were also completed as part of the first phase scope of works.

The remaining sections of Sandton Station required for the Phase 2 operations are now substantially complete. These works included completion of the podium slab over the station complex, the remaining parking facilities, the third platform to service the southbound line to the Rosebank and Park stations and an undercover municipal taxi terminus. The reinstatement of Rivonia Road, which also formed part of these works, was completed and the road was re-opened to traffic in its final two-way configuration during December 2010.

Monthly Construction Updates now focus on progress of the Gautrain Phase 2 works, comprising the underground section between Sandton Station and Park Station and the route between Midrand Station and Hatfield Station.

1. Underground Section

Within the southern portion of the Phase 2 tunnel section between Sandton Station and Johannesburg Park Station, the civil works are complete. Tracklaying within the completed tunnel is also approaching completion and has currently progressed southwards from Rosebank Station to the final section adjacent to the platform within Park Station itself. Test running of trains and testing of the signalling system between Sandton and Rosebank Stations commenced during January 2011 and is ongoing.

The underground works also include the construction of seven emergency access shafts located at intervals along the single-track rail tunnel between Park Station and Sandton Station. These shafts will provide emergency services personnel access to the tunnels below. At the bottom of certain of these shafts there will be safe havens where passengers can gather in case of an emergency. Construction works at four of these emergency access shafts are substantially complete and are ongoing at the remaining three.

The reinstatement of Wolmarans Street and Smit Street is complete and both of these roads are open to traffic. Reinstatement of the two remaining roads bordering Park Station – Eloff and Joubert Streets – is also substantially complete, but these will not be opened to traffic until the station external works are further progressed.

Construction of the Pretoria satellite bus depot is ongoing. This facility is located to the north of the CBD, in the vicinity of the Pretoria Zoo. It is the base from where the fleet of Gautrain feeder and distribution buses that will serve the three stations in the Tshwane area will operate. Maintenance work and major servicing of the buses, however, will take place at the already operational Gautrain Bus Depot, which is located adjacent to the Train Depot and Operations Control Centre in Midrand. Construction of the guardhouse, the office building, the workshop and the utility buildings is well advanced and the concrete hardstand areas are substantially complete.

PRETORIA TO HATFIELD, INCLUDING VIADUCT 7 OVER NELSON MANDELA BOULEVARD

Viaduct 7 comprises a set of “Y-shaped” viaducts and flyovers that carry the Gautrain railway lines into Pretoria Station from the south and then across Nelson Mandela Boulevard and the adjacent PRASA railway network towards Hatfield. Construction of all of these structures is complete and the installation of trackwork and associated railway infrastructure across the decks has also been completed.

Between Pretoria Station and Hatfield Station, a number of bridges crossing the existing PRASA railway line have been either widened or lengthened to accommodate the adjacent Gautrain tracks. All of these bridges have already been completed and reopened to traffic, with minor finishing works ongoing. The extensive lateral support works in cuttings, together with the earthworks and construction of the retaining structures necessary to widen the existing embankments, are complete, as is construction of dividing walls between the Gautrain and PRASA railway lines. Erection of noise barriers and boundary fencing are also approaching completion. Tracklaying operations and the installation of associated railway infrastructure between Pretoria and Hatfield, which commenced during October 2010, are well advanced along the full length of this final section of the route.

B) OVERALL PROGRESS

Construction started at the end of September 2006. Gautrain will be completed in two phases:

1. The first phase was initially planned to be of a 45 months contractual duration, but was completed three weeks ahead of this, on 08 June 2010. It includes the network between the OR Tambo International Airport and Sandton and includes the stations at OR Tambo, Rhodesfield, Marlboro and Sandton, together with the Depot and Operations Control Centre located near Allandale Road in Midrand.

2. The second phase, being constructed concurrently, will be completed during 2011. It includes the remainder of the rail network and stations linking Sandton to Park Station in Johannesburg and the route from Midrand to Hatfield.
