Other parts of the Rotary Group around the UK are also in jeopardy and have been so since May when Australian parent company Hastie Group entered voluntary administration.
The Dublin branch of the company went into receivership last week.
In the UK, Rotary has divisions in Warrington, Livingston, Newcastle, London and Leeds as well as Northern Ireland. It was bought by Hastie for more than £100m in 2008.
There are rumours that Lorne Stewart is on the point of rescuing some or all of the Rotary group.
The Construction Index has asked for a statement from the administrators FTI Consulting, and will bring further details when they are confirmed.
