Tony Douglas's role as managing director of T5 is much wider than simply running the construction project. He has a team of senior directors to look after that. His responsibility is as much to do with liaising with all the stakeholders in the project, from the rest of BAA, to T5's ultimate tenant, BA. He also talks regularly to shareholders, investors and insurers of the scheme and to all the local councils, interest groups and businesses affected by the terminal's construction.
'This is a massive plc in its own right, ' says Douglas of T5.
'So explaining policy, extending influence and expressing clarity externally are very important.
'Internally, my role is to provide a confidence, a belief in what we are doing and to mediate between the energy and dilemmas presented in an organisation of this talent.
Some of the T5 designs are still being finalised so the company can capture the best of the latest techniques and technologies at use in airports as late in the day as possible.
'I take the judgement of when the design is fixed, ' he says. 'I have to create a courage and a leadership that says it's the right time to decide.'
