The investigation has, importantly, revealed that the roof is stable and therefore that the chamber is safe to access in order to implement the initial work to enable its reoccupation.
Arup's European chairman Philip Dilley this afternoon revealed a schedule to target mid-April to mid-May for the works and 'thereafter reoccupation of the chamber'.
The first step will involve the fitting of straps, which will make the chamber safe, to bring it back in to use at the earliest opportunity.
The report also confirms only a lightweight scaffold is required, and therefore work can progress 'at an advanced pace'.
The parliament's presiding officer George Reid said: 'Two weeks ago we established what went wrong in the chamber, today we know how to fix it.
'Based on the report provided by Mr Dilley today, we continue to target mid-April to mid-May for the work.'
The report will be subject to scrutiny by the Parliament's independent structural engineering consultants Atkins and the Health and Safety Executive.
