CONSTRUCTION UPDATE – 31 March 2011

Posted on Apr 13, 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 were completed during March 2011. 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, the route between Midrand Station and Hatfield Station and the Pretoria satellite Bus Depot.

The Phase 2 works are well advanced, with those between Rosebank Station and Pretoria Station, including all testing and commissioning (T&C) activities, being substantially completed during March 2011. Access has been provided to the Bombela Operating Company to the full railway alignment – which includes all stations along this section of the route – and Trial Running between Rosebank and Pretoria Stations commenced on 08 March 2011. Trial Running along the final links to Park Station and Hatfield Station will follow and is planned to commence within the next few weeks.

Trial Running, which follows completion of the T&C process during which all systems and sub-systems are commissioned and tested to demonstrate that they meet required performance standards, is carried out under the control of the Operator. Trial Running comprises numerous drills and exercises, familiarisation of staff with operating conditions and – during the latter stages – running of the full system to the service timetable.

1. Underground Section

Within the southern portion of the Phase 2 tunnel section, all civil works, tracklaying, railway infrastructure installations and T&C activities are complete between Sandton Station and Rosebank Station and Trial Running within this section of the tunnel, under the control of the Operator, commenced on 08 March 2011 and is ongoing. From Rosebank Station to Park Station, all civil works, tracklaying and railway infrastructure installations are also complete, and T&C activities are 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.

PARK STATION

All structural works for the station and parkade are complete, including the concrete ventilation chamber at the northern end of the platforms and the cut and cover linking the station to the tunnel portal. Backfilling of the cut and cover structure commenced during January 2011 and is ongoing.
