We're getting to the finished plan stage of our renovation and our architect has estimated around £120k for the work (I realise that this is likely to increase and have prepared for a shock when actual quotes come in!). In his notes there is a bit about it being up to the client whether or not to instruct a quantity surveyor.
We're at the stage where our plans are being finalised for planning permission, and I think we'll have a structural engineer out before then to make sure the plans will work.
Is it usual to instruct a QS on a project this size and at what stage would you usually add them to the project?
Many thanks!
