Construction services business ISG has secured an £89m project to bring forward the Cardiff Transport Interchange building for developer Rightacres at its Central Square scheme.
The mixed-use project, which is being funded by Legal & General and designed by Cardiff-based Holder Mathias Architects, incorporates about 500,000 sq ft of new space, which includes the 14-bay bus interchange with a covered concourse, 318 apartments for the private rented sector and about 90,000 sq ft of office space
ISG and Rightacres have a pre-existing relationship that includes ISG building the new Foster + Partners-designed BBC Cymru Wales headquarter building and Nr Two Central Square, home to Hugh James and Cardiff University's School of Journalism.
The latest win is ISG's single largest UK construction project of 2019 and takes the contractor's tally of work awarded at Central Square past £200m.
"The Cardiff Interchange has been one of the most highly anticipated developments of recent years and this announcement reflects real collaboration and vision from all project stakeholders to create a mixed-use scheme that delivers for our city," said ISG project director Kevin McElroy.
"Not only will this dramatically improve connectivity for businesses, residents and visitors to Cardiff, but alongside the iconic BBC Wales headquarters, will transform this strategic gateway site."
Jason Hyett, Rightacres project director, said signing of the build contract marked "a great landmark in the project's timeline and is thanks to the input of a great number of people".
Stephen Hill, Holder Mathias partner, added: "The interchange is an extremely complex, challenging and multi-layered project that, once complete, will provide a modern, innovative and truly mixed-use set of environments.
"Not only will it deliver Cardiff’s new bus and coach station, but it will provide a landmark residential offer in a key city centre location and dynamic new office accommodation."
