Interserve has won a £38m deal to construct a new pharmaceutical research centre.
The contractor will design and build the National Biologics Manufacturing Centre for The Centre for Process Innovation in Darlington.
The centre will provide laboratory space, clean rooms, open plan space and pilot plant areas, office, conference and training facilities.
Work is expected to starts on site in April 2014 and should complete at the end of March 2015.
Companies will be able to use the centre to develop, prototype and scale up biologic products, processes and technology. Biologic medical products are made using biological processes rather than chemical synthesis.
The Centre for Process Innovation started looking for a contractor to build the centre in September 2013.
