ISG's challenges of working in a 150-year-old building highlighted in trade press

UK - ISG, Edinburgh, City Centre

Retaining the façade of a 150-year-old Grade B listed building is just one of the many challenges facing ISG in Edinburgh city centre, where we are demolishing the interior of the Mint Building on West Register Street to provide 61,000 sq ft of Grade A office space.

ISG’s senior contracts manager, Allan Currie, spoke to Construction News about the logistical complications involved in the project, which is also located above a live substation servicing most of Edinburgh city centre.

“Once we opened the Venetian building and realised what was really there, [we had] to find a solution that would still allow us to deliver the job,” Allan said.

The existing gable was discovered to be structurally unsafe, and coupled with the façade retention and the fact that all external roads could not be obstructed, the building’s new steel frame had to installed internally.

“We went into the basement first and put the new foundations in there, working in very confined spaces, and then we knocked holes through the floor all the way up through the building to let us drop the new steel frame inside, threading it down through the building.”

Allan said discovering the construction processes inside the listed building had proved to be fascinating for the ISG team.

“When you look at the stone and what else they put in 150 years ago, without a machine – it’s fantastic,” he said.
