The main station will be a steel and internal timber composite roof structure with trains leaving from a second level below the raised the main station concourse.
Approach railway lines will enter the station on raised viaducts supported by V-shaped piers, allowing people and trams to pass below.
Curzon Street station will be the first brand new intercity station built in Britain since the 19th century.
Firms have until 17 January to complete prequalification documents with firms shortlisted to bid in May. The successful bidder is scheduled to be revealed in the second quarter of 2020.
