Queensland government public servants moving into a landmark new office building will be encouraged to buy information and communication technology services from the private sector, despite concerns the industry may not be up to the task.

Due for completion in 2016, 1 William Street in the Brisbane CBD will house the Queensland premier, senior government ministers and their staff, directors general and 4500 public servants, in addition to private sector tenants.

Landmark: an artist's impression of the new building.

An ICT blueprint for the building produced by the Queensland Government Chief Information Office outlines plans for agencies to share infrastructure and buy in ICT services, rather than providing and managing their own.

Agencies would be charged for resources on a fixed or consumption basis and the report flags the need for an advanced billing system to enable this to occur.
