This is the relevant bit, you need a producer statement for high wind areas.

mattwnz:
The thing is that the council has said that the existing producer statement and engineers calculations are for a low wind zone. The same exact sheds are being sold today, and we supplied the council with a producer statement that is less than 12 months old, which says it has only been designed for a low wind area. Yet we were told by the manufacturer that it that it would be fine for a high wind area.

The manufacturer "saying its fine" won't stand with the council. I would challenge the manufacturer to provide you a high wind area PS, or argue that they have provided you something which is not suitable.

Thanks, yes that make it a simple request. Basically if they sold something as suitable for high wind zones, then hey have to have documentation to backup that claim, such as a producer statement showing high wind calculations. I don't think they can then charge me do do their job for them, by hiring a engineer. Will see how it goes as they are still away for the holidays until the end of january.

yep spot on.

i'm a civil engineer and have in the past designed generic structures for installation in various wind zones across NZ (for a manufacturer of greenhouses) - and the key requirement is proof that it complies with the loading code for your site / wind zone

this proof this will include calculations and a producer statement signed by a chartered engineer - and this SHOULD be available from the retailer / manufacturer - especially if they say it was designed for a high wind zone

cheers and good luck
