Replacement of drinking water pipes
Smart pipe replacement under time pressure
Dunea and Heineken needed to replace outdated pipes along the busy Europaweg in Leiden. Due to the tight time frame for the reconstruction and the major traffic and economic impact, an efficient approach was crucial. The challenge: to renew the pipes within the tight schedule and meet all technical requirements — without delays or additional inconvenience.
Key facts of this project
- Sector
- Kabels & Leidingen
- Client
- Dunea
- Location
- Leiden, Europaweg
- Type of project
- Gesloten Front Boring (GFT)
Our approach
BT Engineering developed a smart and feasible design, taking implementation risks into account from the outset. We chose a Closed Front Boring (CFB) method, in which two construction pits are constructed to cross the pipeline without open excavation. This was necessary due to the technical complexity of the location, where various forces converged on a small surface area.
Success factor
The design takes into account risk factors such as the interaction between sheet piling and struts, the pressure load from the drilling machine, and the influence of high water pressure on the subsoil.
In addition, the integrated design minimizes environmental risks such as subsidence due to drainage and possible disruptions to surrounding infrastructure. Thanks to this approach, the contractor can carry out the project without delay and with minimal impact on traffic and the environment.
