Work is anticipated to begin in July with completion scheduled for September 2013.
The new building will be constructed in front of the current school allowing the academy to continue to operate.
The academy project includes health and science facilities and new community facilities for the Edgbaston and Harborne area.
These will include a national standard sports hall, a movement hall, drama studio, a main hall, dining facilities and learning resource centre to compliment the range of classrooms and outdoor learning spaces.
Students at the academy contributed to planning the new academy structure and met with the architects to discuss the main elements of the scheme and to give a ‘student voice’ to what was required in the new building.
BAM’s pre-construction manager Simon Bird said: “We are delighted to be able to use our skills and experience to deliver a vibrant, modern learning facility for Harborne and to enhance the lives of people in the area.”
The academy, which is sponsored by Birmingham Metropolitan College, will have 800 pupils aged 11 to 18.
