The Academy Trust governing the Rydens Enterprise School and Sixth Form College have published an OJEU notice for their expansion plans.
A new school and college is being funded by selling off excess land at the site for redevelopment.
The new scheme will be built on the existing playing fields and the work is set for completion by September 2016.
Up to six contractors will make the shortlist and expressions of interest must be submitted by April 28 via http://www.mytenders.org/search/Search_AuthProfile.aspx?ID=AA0441 or further information can be obtained from [email protected]
