Norfolk wins $82m of work with BHP

Engineering company Norfolk Group has signed an $82 million contract with BHP Billiton for work on rail signalling systems in the Pilbara region of Western Australia.

Norfolk's electrical and communications company O'Donnell Griffin would design and install new and modified rail signalling systems for BHP Iron Ore's Port Hedland inner harbour project, Norfolk said in a statement.

Up to 200 staff would work on the project, Norfolk said.

O'Donnel Griffin will partner with global infrastructure giant GE to develop the rail signalling technology.

Norfolk Managing director Glenn Wallace said the company had a strong focus on continuing to grow its rail business.

"Last year we created a National Rail Group within O'Donnell Griffin to recognise the specialist expertise we can deliver in this area," Mr Wallace said.

"Norfolk has built a strong relationship through our successful work on previous projects which recognises our ability to design and deliver industry-leading rail signalling technology."
