Barclay Mowlem

Barclay Mowlem was an Australian construction company that traded from 1957 until 2006.

History
In 1957, Barclay Bros was founded in Brisbane by Don and Ian Barclay, growing to become one of the largest construction companies in Queensland. In 1958 it expanded into Papua New Guinea when it was awarded a contract to build a new hospital in Madang. In 1971 John Mowlem purchased a 40% shareholding, later taking 100% ownership. It expanded into all other Australian mainland states except South Australia and into Asia.

In 1985, Barclay Bros merged with Roberts Construction, making it one of the top five Australian construction companies. In 1988 it was rebranded Barclay Mowlem.

In December 2005, Barclay Mowlem was included in the purchase of Mowlem by Carillion. With no other Australian operations, Carillion put the business up for sale, with Laing O'Rourke purchasing it in July 2006 and retiring the brand.
