Leadbitter is believed to have fended off competition from contractors including Bam Construct and Willmott Dixon to win the £23 million Swansea University Innovation Hub.
In 2011, the firm won a place on the £300m South West Wales framework which includes contracts for schools and public buildings in Swansea, and for schemes of more than £12m.
Leadbitter has offices in Swansea, Bristol and Cardiff. It is currently seeking local suppliers to undertake work on the development of the £150m first phase of Swansea University’s new Science and Innovation campus, which is being developed by the university with St Modwen, through Vinci Construction UK and the Leadbitter Group.
The Swansea Bay Science and Innovation Campus will include the College of Engineering and College of Business & Economics, and will be a showcase for science, technology, engineering and mathematics.
Phase one will also deliver testing and research buildings, plus accommodation for 2,000 students, an information and resources centre and retail facilities.
