Carillion Alawi or Oman, a subsidiary of UK-based Carillion, has won a £275m contract to build a new parliament building in Muscat.

Designed by London-based architect Q-Dar, the construction work includes the Majlis Oman, the new parliament house, Majlis A’shura and Majlis A’ddowla, together with VIP areas, an information centre, library, offices and other support facilities.

The two-phase contract work has commenced with the Majlis Oman scheduled to be complete by September 2011 and the ancillary works by September 2012.

The parliament is designed to represent the Oman territory with the access gates surrounded by water to represent seas and oceans.

Carillion Alawi has previously built the largest mosque in Oman, the Sultan Qaboos Grand Mosque, and is in the process of building the Royal Opera House for the Royal Court Affairs and the Oman Botanic Gardens for the Diwan of the Royal Court.
