Transport Initiatives Edinburgh, the under-pressure group tasked with installing an 11.5-mile tram line in Edinburgh, has had three more senior personnel quit their job.
At least six key members of staff have now left in recent months after the latest departure of two construction specialists and a risk assessor.
TIE is owned by the city council and is overseeing the project linking the airport with Newhaven.
The work has been riddled with delays, cost overruns and contractor disputes, and the continuing problems may end up forcing TIE to shorten the line to end at Haymarket instead of Edinburgh city centre.
In August, adviser Graeme Bissett walked out on the project, followed soon after by TIE finance and performance director Stewart McGarrity. In November, David Mackay, the organisation’s chairman, also quit.
The latest resignations are Bob Bell, a construction manager on the key InfraCo trams contract; Mark Hamill, a risk manager at TIE, who has quit and is expected to leave this month; and Graeme Barclay, TIE’s construction director.
