Liverpool-based Nobles Construction has won a £1.5m contract to refit Aintree Hospital NHS Trust's outpatient department.
Nobles will strip out the 130,000 sq ft outpatient building and provide new finishes as well as full mechanical and electrical installations.
Peter Linford, director at Nobles Construction, said: "Nobles continues to benefit from its growing reputation for work in the health sector. Our experience proved fundamental in the tender process and we're looking forward to working closely with the client to deliver an excellent facility for the community."
Nobles Construction has worked with Aintree Hospital on other projects including the Marina Dalglish Breast Cancer Unit and the Colposcopy Unit.
