Department of Building and Housing Technical Investigation Reports
The Terms of Reference require the Commission to receive and take into account the results of a technical investigation conducted by the Department of Building and Housing (DBH) into the failure of the CTV, PGC, Forsyth Barr and Hotel Grand Chancellor buildings.
On 30 September 2011 the Commission received four reports from DBH:
- ‘Investigation into the Collapse of the Forsyth Barr Building Stairs on 22 February 2011’ by Beca Carter Hollings & Ferner
- ‘Report on the Structural Performance of the Hotel Grand Chancellor in the Earthquake of 22 February 2011’ by Dunning Thornton Consultants
- ‘Investigation into the Collapse of the Pyne Gould Corporation Building on 22 February 2011’ by Beca Carter Hollings & Ferner
- 'Structural Performance of Christchurch CBD Buildings in the 22 February 2011 Aftershock Stage 1 Expert Panel Report Covering Pyne Gould Corporation Building, Hotel Grand Chancellor Building, Forsyth Barr Building, 30 September 2011'
The result of the investigation into the CTV building is not yet available.
While the Commission expects the results of the DBH technical investigation will be of significant assistance, we will seek our own advice and form our own views. Eminent structural engineer Mr William T. Holmes from San Francisco will review the DBH reports for the Commission.
As required by the Terms of Reference, the Commission is also conducting an independent inquiry into the failure of the same four buildings, gathering and analysing information about their performance during the earthquakes.
All the reports will be contestable in the Commission’s hearings process.
