The project

European Spallation Source, Lund

The latest addition to Europe's scientific research capability, this cutting-edge facility will host the most powerful linear proton accelerator ever built.

Situated near the university town of Lund, Sweden, the Group are building a cross-discipline research facility based on the world's most powerful neutron source. European Spallation Source ('ESS') is a collaboration of 13 European countries, intended to yield discoveries that could benefit the fields of energy, technology and the environment. Designed to house world-leading scientific equipment as well as up to 3,000 researchers, ESS Lund is a testament to the power of collaboration in which the Group is proud to be a part.

The first major project for the Group's Netherlands-based European business, Severfield Europe B.V, this project showcases the Group's expertise in the continent. The scope of the project is to supply, fabricate and erect c.3,000 tonnes of structural steel, roof plates, cladding, filigree floors as well as the erection of precast concrete elements including concrete stairs, wide slab floors and precast hollow walls. The steel fabrication for this large contract is mainly being provided from our Dalton facility, together with certain approved subcontractors, both in the UK and in Europe. This has required close organisation of an international supply chain and workforce to ensure that the project runs smoothly.

Given the extreme sensitivity of the instrumentation to be contained within the facility, the building must be extraordinarily sturdy and resistant to movement. The project design had to take account of the effects of high winds and seismic activity, resulting in specific requirements during the construction phase for extremely heavy welding. Plate steel up to 80mm thick was required for some aspects including a crane beam in the high bay building.

Not only will ESS become one of the world's most modern research facilities, it will also be one of the most sustainable and energy smart research facilities. The facility will use as little energy as possible and all energy will be from renewable energy sources and the waste heat will be recycled.
