Reports on the failure of three central Christchurch buildings will be heard by the Canterbury earthquakes royal commission before Christmas.
Investigations into the collapse of the Pyne Gould Corporation, Forsyth Barr and Hotel Grand Chancellor buildings in the February quake were this month released by the Department of Building and Housing.
The commission will begin hearing submissions on the PGC building collapse from November 28, followed by a hearing on the Forsyth Barr and Hotel Grand Chancellor buildings in the week beginning December 5.
A commission spokesman said there was still uncertainty on the timing of the Canterbury Television building hearing because the department's technical investigation was not complete.
Department building quality deputy chief executive David Kelly said this month that a report on the CTV building, in which 115 people died, was "more complex" and required further analysis.
A provisional decision was made to hold that hearing in March.
Investigations into other building failures in which lives were lost were "ongoing", the commission spokesman said. Hearings into some of those failures will be held in the weeks beginning December 12 and January 23 and 30.
The hearings at St Teresa's Church Hall in Riccarton will resume on Monday, with a presentation on seismicity. The royal commission has to provide its full report to the Government by April 11.
