Bachy Soletanche builds the foundations for Riverside 2
Bachy Soletanche UK has recently signed geotechnical contract for the construction of a second waste-to-energy plant for client Cory. The subsidiary has undertaken to build an underground bunker and foundation piles under the direction of general contractor Hitachi Zosen Inova AG (HZI).
Focus on Riverside 2
Once completed, Riverside 2 will be one of the largest and most efficient waste-to-energy plants in the UK. It will process almost 650,000 tonnes of non-recyclable waste, generating enough electricity to power 176,000 homes every year. The Riverside Energy Park extension will meet a crucial need for waste treatment and energy generation infrastructure in London and the South East City. What’s more, the facility is the only one in the UK capable of receiving residual waste by river. As a result, around 100,000 truck journeys will be avoided on the roads.
Work completed
Geotechnical work included the construction of a 165-meter-long secant pile caisson consisting of 228 cased CFA piles, as well as the installation of 1,273 foundation CFA piles. To guarantee the efficiency and robustness of the installed piles, 10 static load tests were carried out, requiring the installation of 39 CFA reaction anchor piles. Bachy Soletanche collaborated with two companies on the site: Green Piling for the installation of 585 driven precast concretepiles, and Dunton Environmental, a Menard subsidiary, for excavation and the supply of ancillary equipment.
Martin Stanley, Director of UK Operations for Bachy Soletanche, explained on completion of the project:
“Thanks to the experience gained from the delivery of the first Riverside installation in 2008, and based on customer audits of other recent projects, we established a strong relationship with the main contractor early on. As a result, we had a good understanding of the project and were able to work collaboratively with HZI and its partners to address a number of challenges that arose during the course of the program.”
To ensure on-time delivery of the underground bunker, a key element of the project, Bachy Soletanche mobilized four drilling rigs and four service cranes in a restricted area.
The project was completed according to the customer’s schedule, with no delays to subsequent work. This success is a testament to the dedication of the project team, Bachy Soletanche’s supply chain, and their effective collaboration with Hitachi Zosen Inova.
Congratulations to the Bachy Soletanche teams for their excellent work!
