The application to demolish the existing Dumbarton secondary school is set to go before a meeting of the local planning committee by either January or February.
If all goes to plan, construction work could begin in June 2011, with an expected completion date of August 2012.
Interested firms have until 23 December to obtain PQQs from Ken Dee at West Dumbartonshire Council. Email: Ken.Dee@west-dunbarton.gov.uk
