The project
A name, an address and the legal description so a printed sheet says which building it is about, and who it is for.
Property owner
Site facts
Decided by where the site is. Each one selects what a clause shows you instead of the whole table, so leaving one blank is fine: the clause that wanted it will say so.
Wind, corrosion, climate and earthquake zones, wind regions and lee zones, by address.BRANZ Maps
The territorial authority is the council, and it fixes the climate zone: Table C.1.1.2: Climate zones by territorial authority lists one zone for each (two are split, and both halves are in the list). Pick it and the zone comes cited. Where none is picked, a zone read off a map can be typed below.
Rainfall
E1/AS1 Appendix A lists a design intensity for 255 locations. Pick the nearest; the clause reads the figure and cites the table. Where the territorial authority or MRM gives a different figure, enter that too: E1 uses whichever is higher and says which.
Site constraints
What a PIM or a pre-application meeting turns up. Most of these come from the district plan rather than the Building Code, so what they cite is a plan rule.
“No” and “not checked” are different answers, and a sheet that prints the first when the second is true is a false record. Anything nobody has looked at stays unknown.
Nothing recorded yet.
The building
Design decisions more than one clause reads. Change one here, or in any tool's dock, and every tool reads the new value.
Roofs
Every roof the building has, the predominant one first: E2’s flashing table and E1’s gutter sections read the first roof’s pitch, and a section can take its own. Name each as the drawings do.
No roof yet.
