Clarification

Last week Building reported that Mace was working on Foster + Partners’ proposal for an airport in the Thames estuary (“Davis Langdon and Mace back Thames estuary airport”, page 10). We would like to make clear that Mace’s involvement was on an informal basis and that this does not mean that the firm supports the proposal.
