The multi-faceted NT Future project on London’s busy South Bank involved plenty of drama – heavy demolition, the remodelling of production and performing spaces, and the reimagining of public areas.

But Wilsons’ calm leadership ensured that the Grade II* listed icon – and its three theatres – remained fully operational throughout the three year transformation, employing 1,000 staff and welcoming up to 2,500 visitors daily.

He meticulously choreographed the project around the theatre’s packed schedule of evening performances, twice-weekly matinees and day time rehearsals.

Noisy activity was restricted to three hours a day, with the most disruptive work banished to night shifts.

In order to minimise disruption to actors and theatregoers, Wilson introduced bespoke piling and demolition methods to reduce noise.

Lisa Burger, Executive Director of the National Theatre, said: “Dennis was a pillar of strength throughout the construction period.

“Consistently calm under immense pressure, he was never confrontational and constantly looking for a solution. He was always able to see the bigger picture and focus on our project goals and vision.”

Chris Blythe Chief Executive at award organisers the CIOB said: “The NT Future project was fiendishly complex, with surprises that could have sunk a lesser team,  but Dennis’ five star performance and outstanding leadership mark him out as one of the most tenacious, versatile and talented leaders working in construction today.”

A judging team of 22 senior industry professionals spent six months visiting projects and interviewing candidates.

Blythe added: “Once again, there was an extraordinary array of talent on display at CMYA this year and standards were sky high.

“Congratulations to all our finalists and medallists, your achievements have made the industry extremely proud.”
