A large part of the new work is for the Department of Health through several NHS Foundation Trusts in West Yorkshire, Nottinghamshire, Lancashire and Teesside.
Several of these projects support the NHS’s response to the Covid-19 pandemic.
They included the creation of new intensive care units, decontamination facilities and a significant contract to reconfigure and upgrade existing operating theatres in preparation for the return to routine surgery following the initial stage of the Covid-19 pandemic.
Interserve expects further operating theatres will be required over the next 12 months to cope with a backlog of nine million patients awaiting surgery, deferred during the Coronavirus crisis.
This will require a significant investment by the NHS to expand it operating theatre capacity.
Elsewhere, Interserve Construction has secured new business from local authority clients seeking to improve their local highways infrastructure, deliver framework projects with utility companies and new school developments.
Its most recent win is the £11m Hessle Foreshore Tidal Defence Scheme for East Riding of Yorkshire Council.
Interserve will create a 700m long, permanent tidal defence adjacent to the Humber Estuary.
The works will provide protection to low-lying properties near the Hessle foreshore from flooding in the future.
Paul Gandy, managing director at Interserve Construction, said: “In these tough times, with Covid-19 continuing to dampen the economy, our June figures are very encouraging.
“Our new business pipeline remains strong and lays solid foundations for Interserve Construction as we emerge from the Covid-19 lockdown.”
