CONSTRUCTION UPDATE – 30 APRIL 2011

Posted on May 12, 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 to the full railway alignment between Rosebank and Pretoria – which includes all stations along this section of the route – was provided to the Bombela Operating Company in early March 2011. Under the control of the Operator, Trial Running between Rosebank and Pretoria Stations commenced on 08 March 2011, and is ongoing. 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 well advanced.

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 five of these emergency access shafts are substantially complete and are ongoing at the remaining two.

PARK STATION

All structural and building works for the station and parkade are complete, including the cut and cover tunnel linking the station to the tunnel portal, where backfilling is well advanced.

Within the underground station, internal finishes, platform tiling and mechanical and electrical (M&E) installations are all substantially complete and T&C activities are also approaching completion.

The phased reinstatement of Oxford Road adjacent to the station is ongoing. These road reinstatement works have been carried out on a phased basis to enable the two station entrances and the ventilation structure located on the western side of Oxford Road to be constructed. Oxford Road was opened to two – way traffic (two lanes in either direction) during April 2011. The remaining lanes will be opened once the works on the western side of the road have been completed. At the same time, various other roads in the Rosebank area that were re-configured to facilitate traffic flows during construction of the station will be reinstated to their original configurations. These works will be completed within the next few weeks.

External works are also approaching completion, with remaining items being completion of the external pavements along the site boundaries, landscaping and de-snagging.

Construction of the Pretoria satellite bus depot is almost complete. 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. This facility will be handed over to the Bombela Bus Operator within the coming weeks, whereafter trial running of buses along the Tshwane routes will commence.

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, together with the installation of trackwork and associated railway infrastructure across the decks, is complete. Test running of trains between Pretoria and Hatfield commenced during April 201 and is ongoing.

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 are also complete along the full length of this final section of the route. Energisation of the overhead catenaries took place during April 2011 and test running of trains between Pretoria and Hatfield is currently in progress.

HATFIELD STATION

At Hatfield Station, works within the station building and the parkade are substantially complete, apart from de-snagging and the finalisation of M&E testing and commissioning activities.

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.
