Piles for Tunnel Project in Rotterdam


With a population of around 650,000, Rotterdam is not only the second largest city in the Netherlands, as home to Europe's largest seaport, it's also an important transport hub for freight traffic. A wide variety of goods from all over the world make their way to European cities after arriving in Rotterdam by ship. Most of these goods are transported onward from Rotterdam on freight trains or trucks. In order to better direct traffic in the city and permanently alleviate road congestion, a new highway called the “Blankeburgverbinding” (Blankenburg Connection) is currently being built west of Rotterdam between the existing A15 and A20 highways.

The new A24 highway will be approximately 4 km long and will cross the Scheur River by two tunnels. As part of the project, Bauer Funderingstechniek B.V., the Dutch subsidiary of Bauer Spezialtiefbau GmbH, was contracted to deliver and install GEWI piles, which are micropiles with threads. In total, approximately 10,000 t of GEWI material will be delivered by Bauer between July 2019 and May 2020 and installed as 4,500 individual piles.

In the run-up to the actual construction work, preliminary pile load tests were conducted in 2018 to investigate the primary friction properties of the three soil strata at the site. Soft clay, followed by firm clay and medium-dense to dense layers of sand were detected down to a depth of up to 20 m. The design of the GEWI piles for the tunnel ramps was adjusted based on the results of the pile load tests. The installation of the pile foundation for the southern ramp of the future Maas Delta Tunnel, which is 30 m deep, began in the summer of 2019.

'In total, eleven teams with eleven Klemm KR 806 rigs are currently being used in the joint project with our partner De Vries Titan,' says Maarten Daalmeijer, project manager at BAUER Funderingstechniek B.V. 'This way we can be sure to keep to the tight schedule.' In this project, Bauer is installing the deepest GEWI piles in the Netherlands to date, with a final penetration of 64 m below the NAP (Normaal Amserdams Peil), or 'Amsterdam Ordnance Datum' – a height reference point for the Amsterdam water level.
