The contractor’s power division will start this month in the Boston Manor Park area on preparations to install three 66,000 volt gas-filled cables between substations in Popes Lane in Ealing and Bridge Road and Osterley Court in Isleworth.
Murphy will be using a horizontal directional drill to install the ducting which will house the new cables.
This £19m project for Scottish and Southern Electricity is due to be completed by Christmas next year.
