Site Suitability & Design Notes
This kitset is designed for sites up to Extra High wind zone and snow loads below 1.5kPa, with the plans set for earthquake zone 3. Where full building consent plans have not been supplied, the client is to confirm all design parameters, so confirm your site’s wind, snow and ground conditions with our team before ordering. Bracing design is supplied for IBS Rigidrap-XT and GIB sheet bracing to the walls and strap bracing to the roof; the bracing products themselves are supplied by others.
At 5.6° the roof pitch is below the 8° minimum for typical corrugated roofing, so choose a trough/tray or trapezoid profile — NZBC E2 allows these down to 3°. Check that the stud and nog spacings suit your chosen cladding and lining products. All door opening sizes on the plans are frame opening sizes, SFML supplies frame-to-frame connections only unless other arrangements are made, and there is no allowance for architectural design or detailing.
