The work secured by its main structures division in Barnsley covers a mixed bag of projects for unnamed clients in power, manufacturing and the office sector.
All three projects are currently scheduled to start before the end of the year and run throughout 2021.
Mark Smith, chief executive officer of Billington, said: “The award of these three contracts is great news for Billington and is a testament to our team in a continued difficult trading environment.
“We look forward to working closely with the clients to successfully deliver these projects.”
