@CPM_81 Would Architects generally engage a QS? Wouldn't that usually be the Client that does this, with the builder doing it their side?
I have a certain amount of sympathy for the architects. A lot of the time people do actualy come up with the extras to go significantly beyond the initial extimated budget, that's just the reality. And it isn't the job of an architect to price something - agreed though they would/should have a fair idea.
The other thing is it the range of pricing, we did a big job in 2023 and once of the quotes we got was 50% more expensive than 3 other quotes. And one was very low balled. What type of quote should they be designing towards? With prices rising steadily in the last few years, how are they supposed to "keep up" when it's not even their job to price things?
Also, some of the finishes or client decisions have a huge impact on price. Windows, for example. You can go for one of the 2 big/expensive companies, or one of the Irish named ones from down south. There could be 20k difference. All these decisions add up and can materially impact the ultimate price. Decisions around insulation, heating etc all impact price. Not to mention kitchens, bathrooms, flooring, tiles etc.
The other thing is there's a lot of info out there to allow the client to take an amount of responsibility themselves. Speaking for myself, I knew what ballpark we were in having read newspapers, threads online etc. I find it hard to believe that you genuinely felt what he was designing could come in for what you said the budget was when it came in 2.7x the budget. Were you not forewarned of this when it came in 2.4x the budget? Part of this is the cient re-iterating the budget, making sure the architect truly understands. As in, ask him what the new build and refurb square metres are and then ask is reasonable to expect what he's proposing to fit.
