Our client said…

“We’ve a tall building at the head of a narrow ventilation shaft in the middle of a pedestrian access to the O2 arena. We need you to take the roof off, reach down inside it, extract the old dry cooler, replace it with a new, larger model, connect it, replace the roof and all the while ensure that the cooling of critical secure rooms is not impacted. Oh and by the way, you’ve only got a weekend to do it!”

We replied…

“No problem!”
