Firms have been invited to bid for a public sector projects framework covering up to £2.5bn of construction work across the South East.
The four-year South East and London Construction Framework for Major Projects is expected to be worth between £1bn and £2.5bn.
It is thought that up to 10 contractors will be selected for the project - which is being progressed by Hampshire County Council, but will be available to other public sector bodies in the region.
The framework includes plans for schools, libraries, offices, social services properties, museums, leisure facilities, housing developments, universities, health service buildings, police buildings and emergency services buildings among others.
The range of projects undertaken will include construct only, design and build, and develop and construct, with new build, extensions, renovations, repairs and maintenance, and site infrastructure works among the construction work on offer.
Firms have until 23 August to make their interest known.
