GAUTRAIN CONSTRUCTION
Avoiding harm still the focus after first tunnelling death

Construction of the Gautrain project is on schedule, says project leader Jack van der Merwe.

The man with deep pockets, having already spent more than R7,4-billion on the R25-billion project, says work on the rapid-rail link between Johannesburg, Tshwane and OR Tambo International Airport is'progressing well'.

He laments, however, the project's first on-site fatality, recorded underground in September.

He says the international construction industry equation is that one life is lost for every kilometre of tunnel completed, which is never acceptable, but a statistical and unfortunate reality, and a situation the Gautrain project will attempt to avoid at all costs.

With about one kilometre completed, 14 km of tunnelling work remains.

Take a look at the progress as recorded at the end of September, with photos provided by the Gau-train project team.

PARK STATION Tunnelling towards Rosebank station is in full swing. Nearly 15 m of the tunnel has been excavated and eight steel arches have been installed inside the tunnel. The foundation for a gantry crane steel structure at the portal opening is nearly completed. It will be used to hoist excavated rock from the tunnel opening. Construction of the station box and the sinking of foundation pillars for the parkade are in progress

ROSEBANK STATION A concrete platform is being prepared from where the tunnel boring machine will start tunnelling in the direction of Park station. The machine will be ready to start excavation by January next year. Tunnelling towards Sandton station is 15 m from the tunnel opening. Excavation of the station box is progressing. Lateral support braces are being installed to prevent the structure from collapsing while excavation is in progress

MARLBORO PORTAL Tunnel excavation has reached 815 m from the portal opening. The total length of the tunnel towards Mushroom Farm Park will be 2 700 m. Low profile dump trucks are removing the excavated rock to a crushing plant near Linbro Park for recycling. A weigh bridge is being installed to ensure haulage trucks keep to load requirements before leaving the construction site

LINBRO PARK TO RHODESFIELD STATION Construction of viaduct 15 over Pretoria Road/R21 is in progress. Hoardings are being erected around the construction site, which borders existing Metrorail tracks. Seen here is pier shaft construction by means of slide shuttering

VIADUCT THREE Preparations are underway to install the custom-built, imported launching crane which will assemble viaduct three over New Road. Launching girder brackets are being fitted to the pier heads to carry the launching girder, and girder rails have been installed. Seen here is the assembly of the launching girder on viaduct pier heads. The launching girder will be used to assemble viaduct spans

PRECAST YARD The casting of viaduct spans and M-beams are in progress. M-beams are used in the construction of bridges. They are precast in formwork (moulds). When ready to be installed, they will be transported by means of low-bed trucks to the various bridge and viaduct construction sites. The precast yard is the future site of the bus depot
