Decmil Group has won a $90 million contract with the BHP Mitsubishi Alliance to build an accommodation village in Queensland.

Subsidiary Decmil Australia will begin work in April on the facilities near Moranbah for the Caval Ridge mine project in the Bowen Basin.

The new work bolsters Decmil's order book to about $500 million.

"This contract win aligns with DGL's and Decmil Australia's strategic growth plan to leverage expertise and reputation for service delivery of O&G,

mining civil and building construction works into the Queensland market," Decmil chief executive Scott Criddle said.

Decmil first moved into the Queensland market about 12 months ago.

Late last year it struck a deal with Maroon Group to build, own and operate up to 2,265 rooms in the Calliope Accommodation Village, near Gladstone.

"The combined project construction values of the BMA contract announced today and for the Calliope Accommodation Village is approximately $240 million and provides a strong platform to expand both DGL and Decmil Australia's east coast operations," Mr Criddle said.
