Central city Red Zone limited access

As at midday 22 June 2011 access into the central city Red Zone is open to CPEng engineers and their safety(s).

Safety is our primary concern and the reason for shutting the Red Zone – many buildings have suffered additional damage and there have been some collapses.

Entry is for building inspection/evaluation purposes only – no property retrieval/business access is permitted until further notice.

Public Information Update: 1230hrs Monday 18 April 2011

Geotech update

  • Civil Defence geotechnical teams are checking where rocks have come down during the Saturday evening aftershock. They are also checking if existing Port Hills cracks being monitored have widened.
  • The aftershock is reported to have caused rockfalls in Lyttelton, Diamond Harbour, Port Levy, Scarborough, Heberden Ave, Evans Pass Road, WakefieldAve, Peacocks Gallop, Moncks Bay, and Redcliffs. Nothing has been reported west of Heathcote but this is being checked today.
  • The aftershock has reinforced the need for houses in these areas to remain red placarded.
  • The wet weather meant no work was done above Evans Pass Road yesterday.  The road is closed today, tomorrow (Tuesday) and Wednesday.
  • Residents in affected rockfall areas can register for updates at porthillsgeotech@ccc.govt.nz

Business Access and CBD

  • Engineers have completed their checks of indicator buildings in the Central City following Saturday’s aftershock. The aftershock caused more cracking and some falling masonry.
  • The Strategy Building, corner of Victoria and Salisbury Streets, is currently being demolished. This is expected to take 2-3 days to complete. Montreal Street around the building will be closed while this work occurs.
  • The Hotel Grand Chancellor was inspected on Saturday night after the 5.3 aftershock, and there has been no change.
  • Business access in the CBD is on target to continue as planned.

Water

  • Half a dozen crews have been working through the weekend. Admirals Way in South Brighton is the only pocket still without water. Crews are working to repair this.

Liquefaction

  • Saturday’s aftershock caused some further liquefaction and flooding in the eastern suburbs.
