Aquaforce Jetting is carrying out concrete removal for the redevelopment of Four North, St Andrew Street in Edinburgh, known previously as Edinburgh House.
ISG is undertaking extensive refurbishment of the eight storey building, which includes the addition of an extra floor at roof level, open plan floor plates and bike storage facilities. Once completed, the building will accommodate up to 500 staff and offer stunning views over the city.
Structural refurbishment specialist Freyssinet won the contract to create a new lift shaft through the centre of the building, enlisting Aquaforce Jetting Ltd to remove the concrete. Using both hand lance and robotic hydro demolition techniques, Aquaforce is currently breaking out concrete from the 8 post-tensioned floor slabs to facilitate the installation of new lift shafts.
It is anticipated the works will take around 10 weeks to complete.
