I hope this is the appropriate forum - mods, please move it if it isn't.


I'm interested in recommendation for a good structural engineer in Christchurch to review a Cavity Critter video of our subfloor of our 1940s home that was commissioned by EQC.


This is to get an independent review to confirm EQCs report.


Of most concern to me are several joists with (what looks to me as a layman) significant splits along the length. ECQ advised this is natural splitting along the sap line of the timber and not earthquake related, but it would be nice to get this confirmed.


And regardless of if they are quake related or not, we would still like a professional opinion on whether they need to be addressed or are of no consequence.

There were a couple of those in rimu joists under our house, kind on unknown whether the EQ contributed or not, but not a major issue.


An engineer probably charges $250/hour, plus travel, plus whatever to write a report etc, everything loaded to cover professional liability insurance etc.


The fix (if even needed) is probably some galv bowmac brackets/straps and galv bolts, washers etc, and a builder/handyman with a drill and spanner.  EQC had no problem paying for that in our case (though in the end repairs were over-cap and in the insurer's hands).

I would recommend having a chat with the team at Project Structure I know one of the team personally and they know what they are doing.




As Fred99 said, having an engineer in does cost, but if it is to double check something structural, the cost is probably worth it.

Thanks guys.


For peace of mind I think it's probably worth the cost (assuming it's not more than a few hours work).


The problem for us is that the subfloor is very tight, and getting someone under there is nigh on impossible which could make any potential repairs far more expensive and difficult.


We already have the Cavity Crawler video, which I'm hoping might make an assessment by a structural engineer more affordable if no onsite visit is required.


Any further recommendations or suggestions are more than welcome.
