New York-based Turner Construction Co. closed its acquisition of Irish-based contractor and engineering firm Dornan Group, the company announced Jan. 7.

The deal boosts Turner’s presence in Europe and adds to its capabilities. And the contractor, which ranks No. 1 on the ENR Top 400 Contractors with $17.1 billion in revenue in 2023, including $666.6 million in international revenue, says Dornan’s backlog grew from €1.1 billion at the time the purchase was announced last July to €1.6 billion today. Its own backlog is more than $33 billion. 

The companies did not disclose the deal’s terms. 

In addition to Ireland, Dornan has offices in the U.K., Netherlands, Belgium, Denmark, Sweden, Germany and Switzerland. It specializes in mechanical, electrical and instrumentation work. 

“Dornan brings incredible strength to Turner, and this partnership uniquely positions us to serve our global clients better—particularly in the rapidly expanding advanced technology market,” said Peter Davoren, chair and CEO of Turner, in a statement. 

The close comes after Turner announced a leadership restructuring in November aimed at growth in sectors such as data centers, semiconductors, energy transition, industrial and biopharma. At the time, company leaders said the Dornan purchase would support an expansion of its services to new markets and clients. 

Dornan will retain its current leadership team and brand as a Turner company, according to the announcement. 

Turner is a subsidiary of Hochtief Group.
