Mace’s chief operating officer for major programmes, Jason Millett, admitted the scale of Heathrow’s runway construction “will raise eyebrows in terms of how many people we need and where we’re going to get them from, with so many big infrastructure projects going on” in post-Brexit Britain. He added however that: “At least we have certainty about needing people now — there is a skills shortage and we need to invest more in training apprentices and graduates, and this is a long project which gives us an opportunity to deal with that.”
