Triple tower demolition exemplifies collaboration excellence

The demolition of the former Coursington, Allan and Draffen Towers (CAD) in Motherwell, Scotland, impressed the judges who commended the way the team worked closely with the client, consultants, specialist contractors and local stakeholders to move a challenging project forward.

Built in 1970, the three 20-storey residential towers had been local landmarks for more than 50 years. Following unsuccessful work by a previous contractor, the project inherited partially completed demolition, structural instability, incomplete asbestos removal and the discovery of post-tensioned concrete construction.

The partners developed a programme to stabilise the structures, remove hazardous materials and prepare the towers for demolition.

Following detailed assessments, explosive blowdown was selected as the safest and most viable method. Preparatory works included strip-out, removal of glazing and cladding, structural modifications and blast modelling.

All three towers were demolished in a single controlled operation in December 2025. Notably, the project was completed on time, on budget and with zero accidents or incidents, while neighbouring properties, including homes just metres from the towers, remained undamaged.

“This award is a fantastic recognition of what can be achieved when everyone works together as one integrated team,” said Tom Koerner, MD at Thompsons. “The project combined specialist knowledge and experience to overcome an exceptionally complex set of challenges.”

“The three 20-storey towers presented significant engineering challenges, including their vertical post-tensioning system and proximity to neighbouring properties. Addressing these challenges required careful assessment, open communication and a shared commitment to safety throughout the project,” added Perses Group’s Stephen McCann.
