Hi folks. I had an engineer to draw up the plans of my house and apply for planning permission on my behalf. All of this is completed and planning has been obtained. I now want to change engineer for the building stage (as I am not happy with him) and eventhough I have the house plans on soft copy (pdf only), I am wondering if there is anything else I should be getting from the original engineer to move forward with another engineer. Any advice would be appreciated. Thanks in advance
