Alcoa has announced Transfield Services as the preferred tenderer for a $66 million maintenance contract at its Pinjarra alumina refinery.

The deal entails mechanical, electrical and scaffolding services.

Transfield will also be invited to tender for work at Alcoa's Kwinana and Wagerup refineries on an ad-hoc basis under the five year contract, which commences July 1.

"The win increases our market share and we will draw on our extensive experience in providing integrated services to many of Australia's largest refineries," Mr Goode said.
