The new contract wins last month span the health and education sectors, featuring two new schools, including a special needs school, Beacon College in Hereford, two NHS developments and a new community college.
Interserve has also been awarded contracts on infrastructure projects for Northumbrian Water, as well as a refurbishment contract for a specialist robotics centre at Sheffield College.
Nicholas Pollard, chairman of Interserve Construction, said: “We are delighted to have recently secured a further £68.5 million worth of new business on sensible terms.
“This clearly illustrates how Interserve Construction is growing and winning work across the country.
“Our full pipeline for 2020, and already highly secured for 2021, is a testament to the hard work of our colleagues and suppliers, in what has been a gruelling year for every business.”
