Balfour Beatty has won £73m-worth of sea defence schemes in the North-west.
The deal consists of the £20m Anchorsholme Scheme for Blackpool Council and the £53m Rossall Scheme for Wyre Council to replace over 2.9 km of seawalls dating from the 1930s.
The firm said it would use building information modelling on both schemes for both design and construction. It will also train teams from the two councils to use BIM to monitor and maintain the new seawalls.
Work on both contracts will start this winter. Anchorsholme will complete in summer 2015 and Rossall in the summer of 2017.
Both schemes will be funded predominantly by the Environment Agency.
