Well, the first one mentioned only has one post and the other two are in the wrong forum (Subways and Urban Transport). Can a mod just close them all, or maybe merge this with the first one?

All of these have been posted in relatively recently. Not to mention many other contributions from South African forumers elsewhere showing off the Gautrain stations in other threads in the transport section.
Wasn't aware of these, I constantly get asked to create an international thread for the Gautrain so was of the impression that one didn't exist.

I desagree about the wrong forum issue. I think it could be in both forums. This question is object to debate in the Subways and Urban Transport forum. Even if it's going to run a 200kmph it's still a suburban system. Otherwise, the "San Fransisco Bart" or the "Paris RER" threads would be at the wrong place also.

BART and RER are both rapid transit systems linking suburbs to the city centres, with lots of intermediate stations. Gautrain links two separate cities with high speed rail and few intermediate stations.

If a high speed line was built between, say, Philadelphia and New York, with half a dozen stations en route, would you call that a suburban system?

I don't think ANY project is worth 4 threads all to itself that was the only point I was trying to get across.

I'm pleased for South Africa that they're finally investing in infrastructure that is much needed (judging by the road between Jo'berg and Pretoria)!

The rapid rail link being tunnelled under Joburg has won an international award for best global public-private project.

THE Gautrain has won international recognition at the annual Public Private Finance Awards, held in London last week.

On the night some 22 awards were given out. The Gautrain won the Best Global Project to Sign award; other similar awards were Best UK Deal to Sign, and Best European Project to Sign.

"This award shows we can hold our own in the world," said Jack van der Merwe, the chief executive of the Gautrain Management Agency and the Gautrain project leader.

The Gautrain is a public-private partnership (PPP) company, under the broad umbrella of the Bombela Concession Company. It is the biggest PPP in Africa.

Winners are selected by partnership experts to highlight the best deals and public-private companies in the market. The competition is held by the Public Private Finance magazine, a publication that focuses on public-private partnership projects in the United Kingdom and Europe.

"As one of 22 category winners, judges recognised the Gautrain's expertise to overcome the unique engineering and socio-economic developmental requirements of this PPP project," added Van der Merwe.

The project has had to deal with geological difficulties, the topography of Gauteng and the "unique socio-economic deliverables". Other PPP projects shortlisted in the Best Global Project to Sign category were the Britannia Mine Water Treatment Plant and The Conference Centre Dublin.

"It has also managed to make successful an unusual financial structure [part public, part private] and address socio-economic issues - a unique and challenging feature of South African PPPs," said the judges. "To achieve this, a creative solution was developed so that construction began at commercial close, four months before the financial close."

Two phases
The award acknowledges the team of lawyers who put the deal together. "It is attributed to hard-working South Africans like Metja Ledwaba from Ledwaba Mazwai, which was responsible for the legal aspects of putting the Gautrain deal together. This was done in association with international legal consultants Pinsent Masons," Van der Merwe said.

The chief executive of Bombela, Jerome Govender, said, "This confirms our belief that Gautrain is truly a world-class South African project."

The high-speed Gautrain will connect Johannesburg and Pretoria, with a link going to OR Tambo International Airport.

Construction of the Gautrain is being undertaken in two phases, running concurrently. Phase one will run for 45 months and the network and stations between the airport, Rhodesfield, Marlboro and Sandton will be completed by 2010. Phase two will be completed in 54 months, by 2011; the remainder of the network - the link between Park Station and Sandton, and the route from Midrand to Hatfield in Pretoria - will be completed in this phase.

The total cost of the project is R25,2-billion. More information can be obtained from the Gautrain website or from the Gautrain toll free number 0800 Gautrain (0800 428 87246).

Gautrain could win esteemed award
2008/05/27

The Gautrain project has beaten 250 top global infrastructure projects and qualified as a semi-finalist in the prestigious international 2008 Bently Empowered Award programme.

This is in recognition for its innovative customisation of project management software in two categories, according to a recent statement.

Winners will be announced on Thursday 29 May at a ceremony in Baltimore, in the United States.

Gautrain project leader, Jack van der Merwe said although the competition winners for this award still need to be announced, it is a great honour for Gautrain to have achieved semi-finalist status.

One of Bently's products is Project Wise, a document and project management software programme which was customised by Gautrain.

It is used by many other globally recognisable flagship projects such as the London Underground rail system.

The two competition categories in which Gautrain excelled was Innovation in Rail and Transit; and Connecting Project Teams.

In these categories, Gautrain competed with major companies and projects such as the General Motors Corporation, Indian Department of Transport, a new High Speed Railway Line the Atlas Mountains of Algeria and the High-Speed Train Arrival in Barcelona, Spain.
Gautrain's Project Wise document control software programme was modified to suit its unique Private-Public-Partnership (PPP) project management needs.

As a Gauteng Provincial Government initiative, Gautrain is recognised as the biggest PPP project in Africa.

Gautrain's private partners are structured under the Bombela Concession Company and the construction of Gautrain is managed according to a concession agreement.

The software was customised to enable all the private and public partners to work collaboratively in an integrated system.

It was also specified in the PPP Concession Agreement that all documents in the Project Wise system would constitute legal documents with a proper auditable tracking system which would enable the monitoring of the parties' adherence to the contractual agreement.

Project Wise has been used since 2003 when Gautrain was still in a tender and procurement process.

More than 100 000 documents have been filed on Project Wise to date, ranging from geospatial images, photographs, correspondence and reports.

It is used by a variety of disciplines such as engineers, architects, land-use planners and environmentalists working on the Gautrain.

The highly secured system has been customised to facilitate a real time audit trail of documents with a collaborative workflow process and ISO quality management systems.

During the tendering process, the security of the tender documents in the system was never compromised.

The Gautrain Project Team is currently rolling out a system that will link the as-built drawings, designs and documentation to a geospatial system, which will allow users to find documents by clicking on the location and specific structures on a map.

The Gautrain PPP team using Project Wise comprises both local and international partners. – Nthambeleni Gabara, BuaNews

CONSTRUCTION UPDATE - 30 JUNE 2008

A) SOUTHERN SECTION
1. Underground section

PARK STATION





Tunnelling activities at Park Station continued through slightly improved ground conditions, with the single tunnel excavation towards the north reaching approximately 460 metres by the end of June 2008.

Within the station box, excavation continued, reaching final depth in most parts. Waler beam construction and strut installation continued in tandem with the excavation. Casting of the base slab at rail level has commenced.

Piling for the foundations of the multi-storey parkade structure that will be constructed above the station continued.

EMERGENCY SHAFT 1 (HILLBROW)
The land required for Emergency Shaft E1 in Hillbrow will soon be expropriated, after which construction of this shaft will start.

The single-track rail tunnel between Park Station and Sandton Station will feature seven emergency access shafts. 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.





EMERGENCY SHAFT 2 (THE WILDS, HOUGHTON)
At Shaft E2, excavation was completed to the final shaft depth of approximately 50 metres.

Excavation of the adit tunnel linking the bottom of the shaft to the rail tunnel below has commenced. From the intersection of the adit and the rail tunnel, tunnels will be excavated in two directions simultaneously. The one tunnel will head south towards Park Station, while the other tunnel will head north towards Rosebank Station.

EMERGENCY SHAFT 3 (RIVIERA)
Construction of the shaft collar has been completed and shaft excavation approached 10 metres.

EMERGENCY SHAFT 4 (HOUGHTON)
The excavation of Shaft E4 to its 14.3 metre final depth is complete and construction of the base slab, sump and shaft lining are in progress. Being a shallow shaft with direct access to the surface, there is no safe haven necessary at the bottom of this shaft.

ROSEBANK STATION
The Tunnel Boring Machine (TBM) continues to make excellent progress. Excavation of the single-track rail tunnel beneath Oxford Road towards Shaft E2 has reached just over 1 600 metres, which equates to approximately 55% of the distance to be excavated by the TBM.

Excavation of the last part of northern cut & cover section was completed, where casting of the floor slab at rail level has commenced.

Construction of the first lift of the underground station box perimeter walls up to the concourse slab level was well advanced and construction of the concourse slab itself continued.





Excavation of the single-track rail tunnel towards Emergency Shaft 5 reached 324 metres.

EMERGENCY SHAFT 5 (DUNKELD, ROSEBANK)
Tunnelling towards Sandton Station – the only section of tunnelling being excavated from this shaft - has progressed to approximately 600 metres. Excavation of the safe haven chamber at the bottom of the shaft is progressing simultaneously.

Construction of E6 in Illovo will start in 2009, after the tunnel between E5 and Sandton Station has passed below it.

EMERGENCY SHAFT 7 (WESTERN SIDE OF RIVONIA ROAD, SANDTON)
Shaft E7 is located on the western side of Rivonia Road, opposite “The Inandas”. Geotechnical investigations have been carried out, perimeter hoarding completed and site establishment has commenced.

SANDTON STATION





At Sandton Station, where shaft sinking of the south shaft is complete and excavation of the adjacent cavern sections had been excavated approximately 40 metres in each direction, preparations for tunnelling operations are in progress.

Excavation of the north shaft – which will house the atrium entrance to the station - continued.

Piling, foundations and column construction for the three level underground parkade structure continued.

MUSHROOM FARM PARK CONSTRUCTION SHAFT
Two sets of tunnels are being excavated towards Sandton Station. The single track tunnel and side cavern section progressed to approximately 500 metres, while the double tunnel towards Sandton reached 354 metres by month end.

The double track tunnel towards Marlboro Portal reached just over 1 000 metres. Later this year, the tunnel being excavated from Mushroom Farm Park will meet with the tunnel being excavated from Marlboro Portal to form one, continuous tunnel.

Mushroom Farm Park is a temporary shaft, used to provide access for tunnel construction. The community park will be fully reinstated once construction operations are complete.

MARLBORO PORTAL





Excavation of the double track tunnel towards Mushroom Farm Park progressed to 2 189 metres from the portal.

Inside the tunnel, the final lining is being applied to the tunnel walls. Construction of the floor slab to support the railway tracks is in progress. Precast concrete walkways are being installed – these also serve as service ducts for the numerous services required within the completed tunnel. Construction of a centre wall to seperate two sets of tracks inside the tunnel is in progress.

Construction of the cut and cover structure adjoining the portal entrance is ongoing.

2. Surface alignment

VIADUCT 1A AND 11 OVER JUKSKEI RIVER AND EAST BANK ROAD
A continuous long-span elevated rail bridge is called a viaduct. Several viaducts are being built to cross rivers and roads on Gautrain’s route. The precast concrete deck segments for these viaducts are being manufactured at the precast yard.

A launching girder nick-named “Hakuna”, one of three such underslung launching girders deployed on the project, is assembling the viaduct deck segments at Viaduct 11, where placing of segments to 3 of the 5 spans was completed by the end of June. These custom- built girders are launched across the supporting piers to rapidly assemble the precast deck segments. Segments are then glued and stressed together to form the deck spans. This international bridge deck assembly method enables construction to proceed with minimal disruption to existing infrastructure and traffic below.





MARLBORO STATION
Substructure construction for the parking basement and concourse at Marlboro Station is well underway and platform wall construction has commenced.

Construction of a series of underpasses, where the two pairs of railway lines cross below the N3 highway alongside the Marlboro Road Bridge just to the north of Marlboro Station, continued.

The deviated northbound off-ramp of the N3 was opened to traffic in early May, which enabled excavation for the cut and cover sections towards Marlboro Station to commence. Excavation for the main highway diversion (N3 Northbound carriageway) below the extended section of the Marlboro Bridge deck was completed toward the end of June, ahead of this section of road being opened to traffic in early July.

B) NORTHERN SECTION (Depot to Hatfield Station)

VIADUCT 2 OVER MODDERFONTEIN SPRUIT
Side panel installation and casting of deck slabs is complete and erection of the precast bridge parapets, which also serve as noise barriers, approached completion.





TRAIN AND BUS DEPOT
At the Train Depot, Gautrain’s 24 train sets will be maintained, serviced cleaned, and securely stabled overnight. The adjacent Bus Depot will perform a similar function for Gautrain’s dedicated fleet of 125 luxury buses.

Construction of the Depot facillities is well advanced, with both the Bus Depot and the Train Depot administration buildings already complete. The train maintenance workshops will be completed within the next few weeks.





RAIL YARD





The laying of trackwork for the stabling sidings at the Train Depot is well advanced. These are the sidings where the trains are “stabled” (or parked) when not in use.

At the flash butt welding facility, rails are welded into 216 metre long lengths, using high tech rail welding methods. The 216 metre long lengths of rail are then transported as required on specially equipped works-train wagons to the construction site as track laying progresses. Having been placed in position on concrete sleepers, these long lengths are joined together into a continuous length of rail, which eliminates the need for jointed gaps between rails.

Once tracklaying in the Depot has been completed, tracklaying on the mainline sections will proceed outwards from the Depot in both directions. The tracklaying operation is highly mechanised and utilises a wide range of specialised equipment such as works-trains, ballast wagons – which transport and place the crushed rock that forms the base below the sleepers – equipment to transport and place rails and sleepers, ballast tampers and mobile flash butt welding equipment.

PRECAST YARD
The Precast Yard – also temporarily located at the Depot - is equipped with twin concrete batching plants and several overhead gantries and tower cranes that are required to manufacture a variety of precast concrete elements. These include viaduct segments, bridge beams and parapets, tunnel walkway sections and noise barriers. From here, precast elements are transported to the various construction sites as needed. It is currently the largest precast facility in Africa.

VIADUCT 3 OVER ALLENDALE ROAD
Assembly of this viaduct deck was completed at the end of April, with the use of a launching girder, which was then dismantled and transferred to viaduct 11 in Marlboro. Erection of the bridge parapets along the sides of the bridge deck is in progress.





MIDRAND STATION
Stripping of topsoil at Midrand Station has been completed and bulk earthworks activities are under way.

Between the Depot and the Midrand Station, earthworks and drainage were ongoing and good progress was made on the various bridge structures along this section of the route. Deck slab construction at the K60 Bridge continued, the new bridges at Ridge Road and West Road are complete and opened to traffic and piling is in progress at the Dale Road Overpass.

From the Midrand area northwards, relocation of utilities, bulk earthworks, bridge construction and fencing activities continued, with work now underway along most of the alignment towards the south of the Technopark area at Centurion. At the New Road bridge, casting of the in-situ decks continued. Piling, abutment construction, M-beam erection and deck slabs were in progress at a number of the other bridges along this section of the route, including those at George Road, a service bridge, OvP15 and Teal Road.

VIADUCT 4 OVER RIETSPRUIT AND OLIFANTSFONTEIN ROAD SOUTH
Supporting piers for this viaduct are almost complete, with only two pier heads remaining to be cast.

VIADUCT 5 OVER THE N1, BEN SCHOEMAN AND INCLUDING CENTURION STATION
Viaduct 5 carries the elevated alignment through Centurion and supports the elevated Centurion Station platforms located approximately midway along its length. This viaduct stretches from the John Vorster Interchange crossing the N1 in the south and then continues through Centurion to the Jean Avenue Interchange crossing the Ben Schoeman highway in the north.

The sinking of deep foundation shafts for Viaduct 5 at both of these interchanges continues, together with construction of the foundations of the supporting piers of the section of the viaduct within Centurion. At Jean Avenue, pier construction is in progress. Two of these piers are already complete and construction of the in-situ deck sections on top of these has commenced.





Several temporary steel pedestrian bridges have been erected over the N14 highway at the Jean Avenue interchange and across the N1 at John Vorster interchange to provide construction workers safe access across these busy highways.

VIADUCT 7 OVER NELSON MANDELA BOULEVARD
Construction of the foundations is in progress.





Near Salvokop at the approach to Tshwane, construction of an underpass which will accommodate the twin Gautrain rail tracks that will cross underneath the Ben Schoeman highway, continues.

PRETORIA STATION
The existing staff parking area was vacated to enable construction of the Gautrain Station to proceed. Hoarding has been erected around the construction site, relocation of utilities is in progress and foundation construction will soon begin.

HATFIELD STATION





At Hatfield Station, piling for the foundations of the parkade structure is in progress and construction of the retaining wall structures along the adjacent Metrorail lines continues.

Between the Pretoria Station and Hatfield Station, a number of bridges crossing the existing railway line require to be either widened or lengthened to accommodate the adjacent Gautrain tracks. Piling and substructure works for the extension of various of these bridges - including those at Cilliers Street, Walter Jameson Road and Lynwood Road - continued, as did construction works on the new road over rail bridges at Ridge Road and Grosvenor Road.





C) EAST-WEST AIRPORT LINK
3. Airport Link (Marlboro Station to OR Tambo International Airport)

VIADUCT 13 OVER CENTENARY WAY, MODDERFONTEIN
Viaduct deck segment erection for all ten spans of Viaduct 13 has been completed and launching girder T2 was dismantled and transferred to Viaduct 15.





VIADUCT 14 OVER ZUURFONTEIN ROAD AND RAILWAY LINE
Pier construction continued at Viaduct 14, which will span Zuurfontein Road and the adjacent existing railway line. The assembly of launching girder T3 at the east abutment is almost complete.

Several other new Gautrain rail bridges are being built in this area, with work currently under way at ten of these.

VIADUCT 15 INCLUDING RHODESFIELD STATION
The Rhodesfield Station platforms are elevated and will be located approximately one third of the way along Viaduct 15, directly above the existing Metrorail railway lines running between Isando and Kempton Park. The station entrance, concourse and parking area will be positioned at ground level on the eastern side of the existing railway lines.

The piers supporting this section of the viaduct are complete and erection of the deck spans will commence shortly. Launching girder T2, which is now being assembled at Rhodesfield, having completed its work at Viaduct 13, will be used to erect the precast viaduct segments.





VIADUCT 15 INCLUDING OR TAMBO INTERNATIONAL AIRPORT STATION
By far the longest viaduct on the east-west section of the route is the 1.5 km long Viaduct 15, which supports the both the Rhodesfield and ORTIA Station platforms and will carry the double track railway line over the R21/R24 road network to the elevated OR Tambo International Airport Station. The majority of piers have been completed and deck erection will commence shortly. Deck erection will start just west of Rhodesfield Station and will then progress eastwards towards ORTIA Station.

Construction of the external shell of the ORTIA Station concourse is almost complete and is visible above the elevated drop-off road. This is immediately adjacent to the new Central Terminal Building which is currently under construction at the airport.

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

1.
The first phase has a duration of 45 months. 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 in 54 months, towards 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.

Toll-free call centre: 0800-GAUTRAIN (0800-42887246). The call centre is operational weekdays between 6am and 9pm with an answering system after-hours.

Communities are reminded that regular Community Liaison Forums are held in affected areas. These afford residents the opportunity to voice their concerns and have their questions answered by Gautrain officials who are present at these meetings.

CONSTRUCTION UPDATE - 31 JULY 2008

A) SOUTHERN SECTION
1. Underground section

PARK STATION


PARK STATION- STATION BOX VANTAGE POINT


PARK STATION- STATION BOX, BASE SLAB 50M COMPLETED

Excavation of the single tunnel from Park Station towards Emergency Shaft E2 in Houghton had reached approximately 520 metres by the end of July 2008.

Within the station box, excavation continued and one third of the base slab at rail level had been cast. Construction of the columns to support the concourse level slab above has commenced. Piling for the foundations of the multi-storey parkade structure that will be constructed above the station was completed.

ROSEBANK STATION- CONCOURSE

Construction of Rosebank Station is making good progress. Construction of the first lift of the castellated perimeter walls up to concourse slab level is almost complete and casting of these walls above the concourse slab level has commenced. Construction of the concourse slab itself continued

Excavation of the last part of northern cut & cover section was completed during June and 54 metres of the base slab to this section is now complete.

Excavation of the single-track rail tunnel beneath Oxford Road towards Shaft E2 has reached just over 1 700 metres, which equates to approximately 60% of the distance to be excavated by the Tunnel Boring Machine.

Excavation of the drill and blast single-track rail tunnel towards Emergency Shaft 5 reached 365 metres.

EMERGENCY SHAFT 5 (DUNKELD, ROSEBANK)
Tunnelling towards Sandton Station – the only section of tunnelling being excavated from this shaft - has progressed to 733 metres. An approximately 50 metre long section of the safe haven chamber at the bottom of the shaft has also been completed.

Construction of Emergency Access Shaft E6 in Illovo will start in 2009, after the tunnel between E5 and Sandton Station has passed below it.

EMERGENCY SHAFT 7 (WESTERN SIDE OF RIVONIA ROAD, SANDTON)
Shaft E7 is located on the western side of Rivonia Road, opposite “The Inandas”. Site establishment and installation of dewatering wells is complete. The shaft collar has been constructed and shaft excavation has commenced.

SANDTON STATION


SANDTON STATION, STATION BOX SIDE WALLING


SANDTON STATION, SHAFT AND TUNNEL ENTRANCE

At Sandton Station, where shaft sinking of the south shaft is complete, the staggered tunnel towards the south has progressed to 68 metres and main cavern top heading has advanced to 77 metres, with 5 metres remaining to link this to the north shaft.

Excavation of the north shaft – which will house the atrium entrance to the station - continued.

Piling, foundation, retaining walls and column construction for the three level underground parkade structure has made good progress.

MUSHROOM FARM PARK CONSTRUCTION SHAFT
Two sets of tunnels are being excavated towards Sandton Station. The single track tunnel and side cavern section progressed to approximately 570 metres, while the double tunnel towards Sandton reached 397 metres by month end.

The double track tunnel towards Marlboro Portal reached 1 170 metres. Later this year, the tunnel being excavated from Mushroom Farm Park will meet with the tunnel being excavated from Marlboro Portal to form one, continuous tunnel.

Mushroom Farm Park is a temporary shaft, used to provide access for tunnel construction. The community park will be fully reinstated once construction operations are complete.

MARLBORO PORTAL
Excavation of the double track tunnel towards Mushroom Farm Park progressed to 2 340 metres from the portal.

Inside the tunnel, the final lining is being applied to the tunnel walls. Construction of the floor slab to support the railway tracks is in progress. Precast concrete walkways are being installed – these also serve as service ducts for the numerous services required within the completed tunnel. Construction of a centre wall to seperate two sets of tracks inside the tunnel is in progress.

Construction of the cut and cover structure adjoining the portal entrance is ongoing.

2. Surface alignment

VIADUCT 1A AND 11 OVER JUKSKEI RIVER AND EAST BANK ROAD


VIADUCT 1A & 11


AERIAL VIEW OVER VIADUCT 1A & 11

A continuous long-span elevated rail bridge is called a viaduct. Several viaducts are being built to cross rivers and roads on Gautrain’s route. The precast concrete deck segments for these viaducts are being manufactured at the precast yard.

A launching girder nick-named “Hakuna”, one of three such underslung launching girders deployed on the project, is currently assembling the viaduct deck segments at the pair of viaducts - Viaduct 11 and Viaduct 1a – which cross the Jukskei River and East Bank Road.

These custom- built girders are launched across the supporting piers to rapidly assemble the precast deck segments. Segments are then glued and stressed together to form the deck spans. This international bridge deck assembly method enables construction to proceed with minimal disruption to existing infrastructure and traffic below.

Placing of segments to all five spans of Viaduct 11 was completed by the end of July and the launching girder has been moved laterally and reassembled at the adjacent Viaduct 1a, where segment erection will begin shortly.

MARLBORO STATION


MARLBORO STATION, SUBSTRUCTURE CONSTRUCTION FOR THE PARKING BASEMENT AND CONCOURSE


AERIAL VIEW OVER MARLBORO STATION

Construction of the Marlboro Station is well underway. All the parkade columns are complete and casting of ground floor surface beds and the first floor parkade slab above continued. The concourse structure works and building of platform walls are ongoing.

Construction of a series of underpasses, where the two pairs of railway lines cross below the N3 highway alongside the Marlboro Road Bridge just to the north of Marlboro Station, continued.


AERIAL VIEW OVER THE N3 INTERCHANGE AND UNDERPASSES


N3 UNDERPASS

The deviation of the northbound carriageway of the N3 below the extended section of the Marlboro Bridge deck was opened to traffic in early July, to enable excavation of the existing roadway to commence. Construction of the cut and cover box sections to the south of the interchange and of the U-section structure on the east-west line continued. Backfilling over the completed sections of cut and cover box at the southbound onramp and on Marlboro Drive was in progress.

B) NORTHERN SECTION (Depot to Hatfield Station)

VIADUCT 2 OVER MODDERFONTEIN SPRUIT
Side panel installation and casting of deck slabs is complete. The erection of precast bridge parapets, which also serve as noise barriers, have been completed.

TRAIN AND BUS DEPOT
At the Train Depot, Gautrain’s 24 train sets will be maintained, serviced cleaned, and securely stabled overnight. The adjacent Bus Depot will perform a similar function for Gautrain’s dedicated fleet of 125 luxury buses.

Construction of the Depot facillities is well advanced, with both the Bus Depot and the Train Depot administration buildings already complete. The train maintenance workshops are approaching completion, where rail installation and electrical and mechanical installations within the building are now in progress.

RAIL YARD
The laying of trackwork for the stabling sidings at the Train Depot is well advanced. These are the sidings where the trains are “stabled” (or parked) when not in use.

At the flash butt welding facility, rails are welded into 216 metre long lengths, using high tech rail welding methods. The 216 metre long lengths of rail are then transported as required on specially equipped works-train wagons to the construction site as track laying progresses. Having been placed in position on concrete sleepers, these long lengths are joined together into a continuous length of rail, which eliminates the need for jointed gaps between rails.

Once tracklaying in the Depot has been completed, tracklaying on the mainline sections will proceed outwards from the Depot in both directions. The tracklaying operation is highly mechanised and utilises a wide range of specialised equipment such as works-trains, ballast wagons – which transport and place the crushed rock that forms the base below the sleepers – equipment to transport and place rails and sleepers, ballast tampers and mobile flash butt welding equipment.

PRECAST YARD
The Precast Yard – also temporarily located at the Depot - is equipped with twin concrete batching plants and several overhead gantries and tower cranes that are required to manufacture a variety of precast concrete elements. These include viaduct segments, bridge beams and parapets, tunnel walkway sections and noise barriers. From here, precast elements are transported to the various construction sites as needed. It is currently the largest precast facility in Africa.

VIADUCT 3 OVER ALLENDALE ROAD


AERIAL VIEW OVER VIADUCT 3

This viaduct is rapidly approaching completion. Erection of the bridge parapets along the sides of the bridge deck is well advanced and deck waterproofing has commenced.

MIDRAND STATION
Stripping of topsoil at Midrand Station has been completed and bulk earthworks and retaining wall construction activities are under way.

Between the Depot and Dale Road in Midrand, earthworks and drainage were ongoing and good progress was made on the various bridge structures. Deck slab construction at the K60 Bridge was completed and parapet installation commenced. Piling was in progress at the Dale Road Overpass.

From the Midrand area northwards, relocation of utilities, bulk earthworks, bridge construction and fencing activities continued, with work now underway along most of the alignment towards the south of the Technopark area at Centurion. At the New Road Bridge, casting of the in-situ decks is complete and backfilling to reinstate the road above iss in progress. Deck slab construction continues at the Utility Bridge south of George Road and at the George Road Bridge itself. M-beams have been placed at the King Willow Bridge and on the southern half of Olifantsfontein Bridge. Piling has been completed at the ROW and Samrand Road Bridges. Reinforced earth abutment walls are in progress at the Olievenhoutbosch Bridge.

At the Brakfontein Road Bridge, the southern abutments foundations are complete and the construction of the overpass walls is in progress. Excavation at the N1 off ramp at Brakfontein was completed and piling was in progress at the Nelmapius Bridge.

VIADUCT 4 OVER RIETSPRUIT AND OLIFANTSFONTEIN ROAD SOUTH
Supporting piers for this viaduct have been completed.

VIADUCT 5 OVER THE N1, BEN SCHOEMAN AND INCLUDING CENTURION STATION


JEAN AVENUE, VIADUCT 5, SECOND PHASE OF CANTILEVER CONSTRUCTION


AERIAL VIEW OVER VIADUCT 5

Viaduct 5 carries the elevated alignment through Centurion and supports the elevated Centurion Station platforms located approximately midway along its length. This viaduct stretches from the John Vorster Interchange crossing the N1 in the south and then continues through Centurion to the Jean Avenue Interchange crossing the Ben Schoeman highway in the north.

The sinking of deep foundation shafts for Viaduct 5 at both of these interchanges continues, together with construction of the foundations of the supporting piers of the section of the viaduct within Centurion. Construction of the piers themselves has commenced and pier construction at Jean Avenue and at the John Vorster interchange is ongoing. Construction of the in-situ deck sections on top of two of the piers at Jean Avenue is in progress.

Several temporary steel pedestrian bridges have been erected over the N14 highway at the Jean Avenue interchange and across the N1 at John Vorster interchange to provide construction workers safe access across these busy highways.

VIADUCT 7 OVER NELSON MANDELA BOULEVARD


VIADUCT 7 PIER CONSTRUCTION

Construction of the viaduct foundation and supporting piers is ongoing.

Near Salvokop at the approach to Tshwane, construction of the first phase of an underpass which will accommodate the twin Gautrain rail tracks that will cross underneath the Ben Schoeman highway, is approaching completion. During the coming months, the deviated southbound carriageway of the highway will be reinstated to its original position, where after construction of the second phase of this structure below the northbound carriageway will begin.

PRETORIA STATION
The existing staff parking area was vacated to enable construction of the Gautrain Station to proceed. Hoarding has been erected around the construction site, relocation of utilities and demolition of existing buildings are in progress and foundation construction will soon begin.

HATFIELD STATION


HATFIELD STATION, CONSTRUCTION OF THE PORTAL STRUCTURE


HATFIELD STATION, CONSTRUCTION OF A RETAINING WALL

At Hatfield Station, piling for the foundations of the parkade structure is ongoing and construction of the retaining wall structures along the adjacent Metrorail lines continues.

Between Pretoria Station and Hatfield Station, a number of bridges crossing the existing railway line require to be either widened or lengthened to accommodate the adjacent Gautrain tracks. Lengthening of the bridge at Cilliers Street has already been completed and the road re-opened to traffic. Construction works for the extension of the bridges at Walter Jameson Road and Lynwood Road continued, as did construction works on the new road over rail bridges at Ridge Road – where M-beams have been erected over the existing railway lines - and at Grosvenor Road.

VIADUCT 14 OVER ZUURFONTEIN ROAD AND RAILWAY LINE
Erection of deck spans utilizing launching girder T3 has commenced at Viaduct 14, which will span Zuurfontein Road and the adjacent existing railway line. The first two spans from the eat abutment had been erected by the end of July. Foundation and pier construction continued on the western section of this viaduct. Several other new Gautrain rail bridges are being built in this area, with work currently under way at ten of these.

VIADUCT 15 INCLUDING RHODESFIELD STATION
The Rhodesfield Station platforms are elevated and will be located approximately one third of the way along Viaduct 15, directly above the existing Metrorail railway lines running between Isando and Kempton Park. The station entrance, concourse and parking area will be positioned at ground level on the eastern side of the existing railway lines.

The piers supporting this section of the viaduct are complete and erection of the deck spans, using launching girder T2, commenced during July. Three spans of viaduct segments had been erected by month end.

VIADUCT 15 INCLUDING OR TAMBO INTERNATIONAL AIRPORT STATION
By far the longest viaduct on the east-west section of the route is the 1.5 km long Viaduct 15, which supports the both the Rhodesfield and ORTIA Station platforms and will carry the double track railway line over the R21/R24 road network to the elevated OR Tambo International Airport Station. The majority of piers have been completed and deck erection, which has started just west of Rhodesfield Station, will progress eastwards towards ORTIA Station.


AERIAL VIEW OVER VIADUCT 15

Construction of the external shell of the ORTIA Station concourse is almost complete and is visible above the elevated drop-off road. This is immediately adjacent to the new Central Terminal Building which is currently under construction at the airport.

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

1. The first phase has a duration of 45 months. 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 in 54 months, towards 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.
