CONSTRUCTION UPDATE – 12 July 2010

Posted on Jul 14, 2010 in Construction Update - 2010

On 8 June 2010, Phase 1 of the Gautrain System was opened for commercial service. This was truly a world class achievement and took place 19 days ahead of the initial contractual completion date of 27 June 2010.

Gautrain arrival at Sandton Station platform area

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 will be completed by December 2010. These works include completion of the podium slab over the station complex, the remaining 2/3 of the parking facilities, the third platform to service the southbound line to the Rosebank and Park stations, an undercover taxi terminus and the final reinstatement of Rivonia Road.

This and future construction updates will 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.

A) SOUTHERN SECTION

1. Underground section

Within the Phase 2 tunnel section between Sandton Station and Johannesburg Park Station, civil works, including final lining, cable duct installation and walkways, together with the installation of mechanical and electrical equipment, are ongoing. By the end of June 2010, these works had been completed from Sandton to Rosebank Station and are well advanced along the remaining length of tunnel to Park Station. Tracklaying within the completed tunnel is progressing southwards from Sandton.

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 are ongoing at each of these emergency access shafts.

PARK STATION
