Isn’t using foam cladding used as a standard by all builders? Do they mention what type of cladding will be used? There is nothing in our tender. The frame is mentioned - MPG 10, 90mm x 45mm pine frames.
I would think all builders would have to adhere to the same standards as regulated by HIA. So many intricacies 🙄
No EPS is really only used for 1st floor not ground floor. It is very popular but not the only option. Lots of houses are built with brick to both ground and first but now you are restricted in your house design (no offset between ground and first floor, boxy design) or you need a lot of structural steel which is mega $$s.
Did they say what the stud centres were? 90mm x 45mm would be standard for structural but you can use thinner ones for noggings etc. I assume for 1st floor, they will stick with Hyjoist. Enquire about Hebel powerfloor for 1st floor if you want that solid feel. Also ask whether they fix ceiling plaster to aluminium battens for large areas like LDK,
