Brookhaven - GeoTech investigations have started

GeoTech investigations commenced in Brookhaven in early February.   All of the approx 372 properties are zoned TC3. (see photos of GeoTech last week in Delta Way http://www.brookhaven.net.nz/photos.htm)

AMI have scheduled approx 15 so far and the number is expected to rise as people look at their options and make decisions.  Work will be progressively undertaken during this month and through the winter.  After the investigation a report is made and sent to Arrow. 

The next step usually is a structural engineer is engaged to recommend and design suitable foundation. 

Then a registered surveyor conducts a survey to confirm boundaries and determine the height of the new floor in order to comply with Variation 48 of CCC Flood Plan.

How does one get to GeoTech Report you may be asking?  This is a general overview based on feedback from residents who are AMI/Arrow International clients.

1.  EQC determines that your house is overcap.
2. Private insurers make contact with homeowner to advise your property will be managed by their Project Management Office(PMO) e.g. AMI uses Arrow, IAG use Hawkins etc.
3. PMO visits property and generates a scope of works or detailed repair analysis  (this is additional to EQC scope).
4. Draft report on the scope is sent for property owner to check and advise variances.
5. Redraft of report by PMO to include changes or variations.
6. Recommendation is made by PMO to private insurer as to Repair or Rebuild.
7. Owner is notified and repair or rebuild options are presented..
8. If PMO recommend a rebuild and property owner wishes to rebuild on existing site, Geotech is ordered by PMO.

Rules on damaged TC3 sites delayed

Foundation guidelines for earthquake-damaged green-blue Canterbury properties will not be ready until mid-April.

The Department of Building and Housing (DBH) is developing foundation designs for quake-damaged houses classified technical category 3 (TC3) by the Canterbury Earthquake Recovery Authority (Cera). The guidelines had been scheduled to be released last month.

The 28,000 TC3, or green-blue, properties are considered to be on the most badly quake-damaged land able to be economically repaired. Houses in the zone needing to be rebuilt or have foundation repairs must meet new foundation standards.

DBH building quality deputy chief executive David Kelly said developing the new techniques had been "more complex than anticipated".

"As soon as you get into work like this, which is new work, there are things you don't know about simply because you can't anticipate it. It's the nature of the work really," he said.

Foundation designs would fall into two broad categories – stabilising the land and "deep piling and making sure the connection to the foundation is properly thought through".

Geotechnical and structural engineers were taking advice from international experts to ensure the new standards were robust, Kelly said.

"We really appreciate that people are anxious to see this work because they want to get on with life, but the worst thing we can do is get it out and be inaccurate," he said. "There is certainly pressure on us to move as quickly as we can, and we are trying to."

Foundation designs that involve land remediation will be new ground for insurance companies as they do not insure land as part of house policies.

AMI Insurance earthquake recovery executive manager Peter Rose said the company had no problem with the designs involving land remediation.

"We believe we have responsibility for any necessary strengthening in the land as it relates to the appropriateness of the foundations," he said.

IAG Canterbury recovery executive manager Dean MacGregor said the insurer took a similar position, but "only at a philosophical level".

"We would definitely consider it on the basis that if it wasn't going to cost any more than we would have paid for those foundations anyway."

The Earthquake Commission is due to start its geotechnical assessments on more than 8000 TC3 properties with foundation damage soon.

Customer services general manager Bruce Emson said delays from DBH would not affect the process. It was already possible to repair some TC3 properties with foundation damage.
