ISG’s innovative work to overcome a multitude of complexities on its Liverpool Lime Street development has been profiled in a feature-length Construction News editorial.
Working alongside Ion Developments, ISG is nearing completion on its £39 million project to transform the site opposite Lime Street Station, a scheme that comprises ground floor retail space, a 10-storey, 412-bed student accommodation block and a three-storey Premier Inn hotel with 101 guest rooms.
The site’s location between two Grade II-listed pubs on the busy Lime Street city centre location has presented the team with a number of logistical challenges since construction began in November 2016.
ISG needed to close Lime Street to enable it to complete complex demolition of two existing buildings, and also carry out intricate work to level the uneven ground on site, work which required lengthy planning and contractor engagement from the outset.
According to senior project manager, Shaun Boylan, however, the most challenging aspect of the build involved the complex 1,300 tonne steel frame, an innovation that was necessary not only to make sure the retail space could carry the weight of the buildings above it, but to allow the client to have maximum flexibility when letting out the area.
“At the point ISG went into contract, the client didn’t know who would be letting the retail space and wanted maximum flexibility,” says Shaun.
“This was a key design challenge right from the outset.”
Because the need for maximising retail space had prevented the use of bracing, a complex ‘moment frame’ had to be developed, entailing thick beams every four or five gridlines to reinforce the structure – a structure that Shaun says will take some beating.
“Taking the bracings out of the retail space and adding the moment frames has added the best part of 300 tonnes,” he says.
“Some of the connections, I’ve never seen anything like it – it’s a heavy frame.”
The Liverpool Lime Street project is due for completion in July 2018.
