GIBB Engineering has completed a feasibility study into the construction and operational feasibility of connecting the existing Western Precinct to Midfield Development at OR Tambo International Airport.

The research could lead to the airport being divided across the two major terminal precincts by an underground tunnel that would bridge the gap between the aircraft stands and the cargo/terminal buildings.

Tunnel connectivity is seen as key to the future master planning and infrastructure development of the airport. If constructed, the tunnel would enable the linking of the current Western Precinct (existing terminal and associated aprons) to the new future cargo and new mid-field terminal developments.

The linkage, once fully constructed and operational would provide access to shorter connection times of people, baggage and services within the current infrastructure and future airside developments.

Aviation service providers (baggage handlers, refuelers, marshallers) would benefit from shorter distances and travel times to get to servicing aircraft. Airlines would be able to improve aircraft connection times and ensure that aircraft can spend more time in-flight than waiting on the ground to be serviced and/or filled up with passengers.

The scope of work defined in Phase 3 of the study evaluates the tunnel connectivity time and a possible route between the two terminals, an overall assessment on the closure of aircraft facilities during the construction, the cost implications, the duration of the project, the advantages of the new connecting tunnel and the viable tunnel and road connector assess points.
