One of Britain鈥檚 best known project managers prepares to retire after 30 years

When David Trench decided that his construction and consulting firm had come as far as it could alone, he and his partners promptly put it on the market. Last week, White Young Green (WYG) happily pocketed the firm that project managed the Millennium Dome and the British Library.

Trench is confident that any changes to the firm he founded will be minimal. 鈥淭here are now 2000 people in WYG. They have to have certain rules or else it would be chaos. I don鈥檛 think we would go out now and employ someone on a large salary without asking the directors of WYG first, but that鈥檚 exactly what I would expect.

鈥淚 think we鈥檒l continue with our own culture and stay in our niche market. WYG thought we were worth buying so it鈥檚 not going to set about destroying us.鈥

Trench is a man who has lived construction from his earliest days 鈥 he is the son of the late Sir Peter Trench, a former managing director of Bovis. However, one reason for the merger is that he is planning to stay on until September to project manage his firm鈥檚 integration into WYG, then retire. 鈥淚鈥檓 64 now and it鈥檚 time to hang up the boots,鈥 he says.

Bernard Ainsworth, who has worked with Trench many times over the past decade, most notably on the Dome, is unconvinced by this: 鈥淗e鈥檒l keep popping up. Taking it easy? Maybe. But David retiring? I鈥檇 put a question mark over that.鈥

Trench may prove Ainsworth wrong. He is determined to bow out, particularly after a turbulent 2005, in which he quit his role at the Ascot redevelopment.

鈥淒elivery gets harder the older you get. It needs a lot of personal drive and push so when Howard Shiplee [now the London 2012 construction boss] joined Ascot doing the same job as me under a different title, it got complicated,鈥 he says. 鈥淏eing the older veteran and a bit tired, I left him to it.鈥

However, Trench is known for his refusal to quit. The Dome team were under constant pressure, but he never lost faith in the project. 鈥淚 never had a moment of thinking we wouldn鈥檛 get it done on time,鈥 he says.

Richard Coffey, who worked with Trench on the Dome says it was his colleague鈥檚 drive that kept the project on track. 鈥淭here were times when people were saying 鈥榚nough is enough鈥 and he would say 鈥榥o, come on, we can do this,鈥 so we did.鈥

Despite public condemnation of the Dome, Trench is convinced it will still be a success. 鈥淚t was bad timing. It was completed as the Blair honeymoon was ending and it was an easy football to kick. Everyone said it was a waste of money but the cost of the construction worked out at 拢300 a square metre. I defy anyone to build anything cheaper than that. The Dome鈥檚 five time the size of the Albert Hall. It will make a huge comeback.鈥

Trench admits he will miss his career, but says travelling is now his priority. 鈥淗e could do with time to work on his golf,鈥 adds Coffey, 鈥渁s long as he gets rid of those tartan trousers.鈥
