The construction and civil engineering contractor has been appointed to build one of the largest Tesco stores in the North West.
Britannia Construction said it has secured £30m of business so far in 2011.
Paul Halfpenny, Britannia's managing director, said: "We have been appointed by developer Morbaine to work on the redevelopment of its Ashley Retail Park in Widnes, undertaking the construction of a new 120,000 sq ft foodstore and filling station for Tesco, set to be one of its largest stores in the North West. The store will be built on stilts, partly covering the car park, with access to the sales deck via lifts and travelators located in a glass topped atrium."
Halfpenny added that the store is due to open in spring 2012 and Britannia will commence construction over the next few weeks.
Britannia was picked for the work ahead of Vinci, Bowmer & Kirkland, Barr, Simons Group and Watkins Jones.
Tesco has entered a 25 year lease for a foodstore and petrol filling station at Morbaine's Ashley Retail Park.
