Bauer Indonesia completes Expansion of Taxiway at Jakarta Airport


The Soekarno-Hatta International Airport, located in Cengkareng, Banten, suburb of the Indonesia’s capital city, Jakarta, is one of the largest airports in Asia and 17th world’s busiest airport with an annual passenger volume of around 63 million (as of 2017). In order to deal with the increasing number of flights (now at over 447 thousand flight movements per year) and to optimize the time taken for ground handling of individual aircraft, a new connecting taxiway will be constructed to connect the existing runways at east side of airport. Currently, there is only one connecting taxiway located at west side of airport which supported for all aircraft’s movement.


P.T. Bauer Pratama Indonesia, the local subsidiary of Bauer Spezialtiefbau GmbH, was commissioned by P.T. Hutama Karya as main contractor of P.T. Angkasa Pura II (Persero) – Indonesia’s Airport Company and the biggest Indonesia’s airport operator – to carry out the ground improvement work for the construction of the new connection taxiway.

The project title is “East Connection Taxiway Phase 1” which included two main tasks: extensive ground improvement for the connection between the north and south runways, and foundation work for a taxiway bridges over the airport’s main access road. This project is a continuation of the previous “Secondary Apron” project that has been completed on May 2017 located at the north side of the airport where Bauer has also carried out ground improvement work of 98,300 square meters as initial part of East Cross Taxiway.

The ground improvement work needs to be provided to increase the capacity of in-situ soil prior to pavement work. After improvement, the in-situ soil which is dominantly soft to medium stiff silty clay is expected to reach a CBR value (mechanical strength) of 6% under the pavement layer and the allowable settlement at a maximum of 100 mm in 10 years after construction.

The ground improvement was executed with 5- to 16-meter-deep Full Displacement Columns (FDC) over a total area of 199,000 square meters. And for foundation of the taxiway bridges, a total of 1,072 bored piles with a diameter of 1.2 meters was drilled to a depth of up to 37 meters. Three Bauer BG 14 rigs, one BG 22, one BG 28 and its accessories were in operation. The project commenced in February 2018 and was completed over a period of eight months in October 2018.
