The continuing construction boom along the river has seen firms like Balfour Beatty and McAlpine seek expert advice on keeping workers safe near the water’s edge.

Ant Eddies-Davies, who runs Live the Adventure in Shropshire, has been sharing his rescue skills with builders having previously trained everyone from international defence forces to emergency services in how to stay safe on the water.

Eddies-Davies has been focusing on sites around Canary Wharf.

He said: “We have run courses this year for a number of leading construction companies who are building alongside the water’s edge.

“Regulations mean everyone working near water needs to have proper safety training and protection.

“It makes a lot of financial sense for companies to bring us in to help train up their staff rather than pay water patrols for months and months on end.

“This is a great project to be involved with and I hope my knowledge will ensure the staff are fully up to speed with the correct procedures.”
