Murphy was awarded the initial £37.8m enabling works contract for the station in January.
Beaulieu Park station is currently expected to be completed by end of 2025. Once open, the station will be managed by Greater Anglia and served by its fleet of new trains with services into London.
Katie Frost, Network Rail’s route director for Anglia said: “J Murphy and Sons have made an excellent start with the enabling and civils works and this contract award will allow us to seamlessly continue to deliver this amazing new station for Chelmsford without pause.”
Chris Cayton, Managing Director – Transportation, J Murphy & Sons Ltd said: “We’re very proud to be continuing our long partnership with Network Rail through the construction of Beaulieu Park station, a major enhancement to the transport network in Chelmsford.
“Significant progress has been made by the Murphy team over the past few months, including modification to the rail systems, groundworks and piling for the station building.
“In the coming months residents will see their new station take shape, as the platforms are constructed, and the steelwork is erected, ahead of major commissioning of the railway infrastructure at Christmas.”
