Marks & Spencer, Grafton

When a major urban development is taking place – and 44 adjoining owners and leaseholders all have to be kept on board – it’s essential that all problems are anticipated and solutions found before any works can commence.

This was the challenge facing Hegarty Demolition when it was contracted to convert the former Brown Thomas landmark premises into a modern shopping complex. Demolition works included the selective removal of old three and four storey buildings, the retention of protected facades on Grafton Street, Duke Street and Duke Lane, the retention of a protected building on Duke Lane (while constructing a basement underneath) and the protection of retained buildings on Duke Street.

A modular steel frame support system was erected on all facades (15m high) over footpaths, with canopies and fans to protect pedestrians. In this busy urban location all 44 adjoining owners/leaseholders were dealt with and the project planned in detail to ensure uninterrupted continuation of business in buildings and shops surrounding the site.
Strict Health & Safety measures were implemented and environmental controls put in place to monitor all aspects of the works, i.e. noise and vibration levels, dust emissions and Code of Conduct for all site operatives. Incidentally, this was one of the first projects where smoking on site was prohibited. Demolition in these sensitive locations was labour intensive and the removal of rubble and debris took place outside normal trading times – mostly at night and early morning.

Enabling Works included basement excavation, underpinning retained adjoining buildings, earthwork support systems, pumping & dewatering. An intricate temporary works system was erected under No. 5 Duke Street (protected structure). This allowed the excavation and construction of a double basement.

The full scope of the Enabling Works was completed skillfully and professionally to a tight programme schedule in an active and busy commercial location without a hitch or claim from adjoining owners.
