Turner Construction Company is to acquire Dornan Engineering Group, a specialist mechanical, electrical, instrumentation and commissioning engineering contractor with operations in Ireland, the UK, Continental Europe, and the Nordics.

The transaction is subject to the customary merger control approval process in the European Union.

Dornan's 1,000 direct employees will deliver approximately $760 million (€700 million) of work in 2024. Dornan’s backlog of work is approximately $1.2 billion (€1.1 billion). Dornan delivers services on complex large-scale projects for blue-chip clients in the advanced technology sector, including data centres and biopharma facilities. The Group also delivers key projects for clients in the industrial, healthcare, commercial, aviation, and education sectors.


Turner is long recognised as a leading builder of advanced technology projects in North America and Dornan is a leader in this market in Europe. Both companies have well-established long-term client relationships. The combination of Turner and Dornan creates a business of significant scale in Europe with the ability to deliver an increased portfolio of work and a wider range of services.

Turner has expanded its service offering in Europe and is working on advanced technology projects in the Netherlands and Spain. Through the complimentary services of Dornan, Turner sees a significant opportunity to expand its presence in Europe with new and existing clients.
