Meet Balfour Beatty’s HS2 ‘superhub’ supremo

A large programme of work like this gives social value benefits and career opportunities. There's talent out there, but not always the opportunities. HS2 has given massive opportunities to a lot of people who wouldn't otherwise have had them: 2,000 people will be employed on Old Oak Common.

The Old Oak Common project has been on site for three years now. What are the main challenges ahead for you?

It's a logistically complicated project and interfaces with three railways. That's why we’ve gone for a ‘top down’ construction approach of the station box. That part is mostly complete. I’ll be looking ahead to the superstructure and the roof, which is complex, and there are 52 lifts and 44 escalators to install. That means a lot of trades to manage. The 4D model will be important when we look at the constructability.

One important thing I’ve always found with major projects is understanding and strategically managing the transition of the team through the phases of the project. There are a lot of civil engineers at the start, but then you need a plan to phase the project into the building of the superstructure, the fit-out, the testing and commissioning.

You’ve been at Balfour Beatty 44 years, with tremendous major project experience, notably on Heathrow T5, T2B and on Crossrail. What are the main things you’ve learned from these jobs?

I was on T5 from start to finish – six years – and it was probably the best job I worked on: the safety culture, the approach to collaborative working, it was groundbreaking for the industry.

I think relationship building is key. On the Whitechapel Crossrail station, London Underground were embedded in our team, plus London Overground. It was probably the most complicated Crossrail station: we had 14 different configurations to manage, and I was there right through the testing and commissioning stage.

But when it came to the handover, it was relatively easy compared to the other stations, because we'd already formed the relationships. So, we learned the importance of having your stakeholders in the team, and not seeing them as a third party.

How has the digital perspective changed your role?

Heathrow T2B was probably the best project I worked on for 4D modelling. We changed our methodology, from ‘bottom up’ to ‘top down’ construction, by running scenarios through the 4D model and changing the plant positions to dig from north to south.

We spent a long time reaching that decision, working with designers and supervisors and specialists, and we saved six months on the programme.

Telematics are helping with our carbon reduction. You understand how much plant idling time there has been, how productive the equipment has been. An important part of my role is looking at what we can do to use the equipment more efficiently.

You are an FCIOB. Has that helped your career?

I was reporting to Mike Peasland, when he was Balfour Beatty CEO (2010-13). Mike is FCIOB and he pushed me to apply for CIOB membership and said he would act as my sponsor. I told him I'm an electrician by background, expecting not to be accepted, but when I did the interview, the assessors were very interested in my project work overseas (I’d worked on power plants in the Middle East and Indonesia, the Alexandria Bibliotheca in Egypt, a rail project in Hong Kong). And they said they felt I could go straight to fellow.

Up to that point in my career, I had a bit of imposter syndrome; I left school at 16, I don't have a degree. Getting that FCIOB recognition gave me a great deal of confidence. 

After that, I was asked to manage the change programme for Balfour Beatty and manage the Dubai business. That was interesting. But I always felt more comfortable running major projects than a business. 

Any career advice you’d give to aspiring major project directors?

Take opportunities, take risks, stretch yourself. Speak up and make your ideas count. Don't get hung up about senior people: they’re human beings, go and talk to them and learn from them. Get a mentor, build a network. Don’t expect your career to be laid out in front of you – you need to own it and manage it.
