HS2 logistics hub will help cut carbon emissions

Our Skanska Costain STRABAG JV has constructed a 30-acre logistics hub where waste from our London tunnels and other local HS2 sites will be processed. The hub, near Willesden Junction, will form the beating heart of the logistics operation for HS2 in London.

The hub will process the 5.6million tonnes of earth which will be excavated to allow construction of HS2’s 26 miles of London tunnels. Once processed, it will be taken by train to three locations across the United Kingdom to be re-used.

At its peak, eight trains will leave and arrive at the logistics hub every day, maximising the use of rail freight in the construction of HS2 in London and reducing by one million the number of lorry movements on the UK’s roads. It will also reduce carbon emissions for logistics by 40 per cent.

New zero trim technique will transform construction

Cementation Skanska, working jointly with the Skanska Costain STRABAG JV and specialist supplier Hercules Site Services, developed the new zero trim piling technique which has the potential to become a game-changer for the construction industry.

MORE: Zero trim will cut health and safety risks and significantly reduce carbon emissions, cost, noise and programme durations.

The technique uses a vacuum excavator that sucks out excess concrete from a pile while it’s still wet – rather than overpouring concrete and leaving site teams to break out the excess concrete afterwards. This can lead to health problems, including hand-arm vibration syndrome, hearing loss and silicosis. This new approach removes the need to do this, creating a safer method for people in the industry.

HVO trial prompts use across Cementation Skanska’s plant fleet

Cementation Skanska will be using Hydrotreated Vegetable Oil on all its plant fleet, including piling rigs, from 1 January 2022 after a successful trial carried out in collaboration with HS2 and the Skanska Costain STRABAG JV.

MORE: HVO was first used on a Liebherr LB36 piling rig with a 390 kW engine, the largest engine to pilot the use of the high performance fuel Green D+.  The trial collected and compared data with the engine running on diesel and on HVO fuel alone. The data, verified by Brighton University, revealed that CO was reduced by 57%, NOx was cut by 38% and PM reduced by 36% when the engine was run on HVO.  

The decision to use HVO will lead to significant carbon savings compared to red diesel and support our aim of becoming net zero for carbon emissions by 2045.

Cutting edge 3D concrete printing will cut carbon by 50%

3D concrete printing technology will be tested in 2022 by our Skanska Costain STRABAG JV team on HS2 and could halve carbon emissions.

MORE: The innovation, which represents a nmajor leap in construction technology, is expected to simplify the build programme and deliver environmental, cost and community benefits when it is used on HS2 for the first time.

As flexible mobile technology, 3D concrete printing means the technique can be used in physically restricted areas so there is no need to develop complicated and potentially expensive logistical plans. In addition, 3D printed concrete delivers a low carbon, quick drying solution that saves time.
