Ask your builder to explain this for each one and confirm to you in writing. Don't sign until you understand the differences and rationale for each performance solution as well checking the engineers signed validation document for each solution.

This all ads up over thousands of builds.

I want to push back on some of these knowing I won't win them all. But I think a non-negotiable for me is the weaker mortar particularly as I will have a pool next to the house and chlorinated water splashing over the bricks regularly. I assume this could wear away a weaker mortar mix? The reduced water proofing doesn't sound so bad as it is areas that won't see a lot or any water. The shower and bath will still be waterproofed. I don't quite understand the 20mm DPC one - would this be an issue if we end up with garden beds next to external walls, and hence more moisture? I'm very close to just walking away on this build as they have raised prices substantially including a doubling of our slab cost from tender to contract stage. Realistically will Henley negotiate on any of these performance solutions??

The shower and bath will still be waterproofed. I found the Porter Davis discussion (below) but there has been a lot of other discussion since then. Waterproofing is the best keyword to use if you do a forum search. viewtopic.php?p=1275656#p1275656 wixy I don't quite understand the 20mm DPC one - would this be an issue if we end up with garden beds next to external walls, and hence more moisture? The DPC is to stop rising damp. It use to be outwardly visible but aesthetics often subjugate function. Having a garden bed against the house is not a good idea, particularly if you build on reactive soil. You need to do a forum search on this topic as well. wixy Realistically will Henley negotiate on any of these performance solutions?? Anything is negotiable (often at a cost) but Performance Solutions are now engrained in the Henly culture and work practices. Performance Solutions use to be called Alternative Solutions. I hated the name change because having a performance option most often signifies optioning something superior. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: Builder has proposed performance solutions - are these o 10Mar 03, 2023 10:33 am The stated principle of the NCC is its a 'performance based' code. There is inbuilt flexibilty to vary from DTS which can be of benefit to homebuyers and builders however i would want to fully understand the alternative, see the prior validation and consider cost/benefit before agreeing.
