In addition, does anyone have experience of getting into this without a construction background?
Happy to have a chat. I'm a charted building surveyor and engineer (a sponsored STRE was my second career).
Local authority is good. It's how I started many years ago originally as a land surveyor. Building surveying or building control are still options BUT many local authorities use consultants, outsource work or self employed Surveyors working on contract.
Private practice is a meat grinder. You're only as good as you're last project and if the client gets pissy, the senior partners get pissy...with you.
An MSc is good
I have an ONC, HNC, BSc and a post graduate in building conservation. They get you in the door as a junior to start your professional competency. You will not progress until you get chartered and that means the silk tie, pin stripped suited Royal Institution of Chartered Surveyors and you'll need documented experience (projects, reports, specifications, diagnosis). I passed first time. Most don't and return a year later. ( I was lucky, land survey, local authority, police force (looking after property) building society (looking after planned maintenance, then all maintenance then all the property and RE reserve, still quite young and a student member of local RICS committee.You had to play the game.
If you get up the food chain it's good. If you end up in a practice where you are running round juggling client's budgets, requirements, legislation, contractors and bastard senior partners it's not so good and until you are chartered unless you can get in with local authority you are at the bottom.
It's like diferent regiments/corps. Some good, some fun, some full of bullshit.
I have RICS, FCABE and CBuildE but that took a lot and you're always learning.
As said above, you often have to diagnose without opening the patient (or lifting the bonnet to explain why the car won't start) and that needs experience.
I've just spent two days going over a £6m mansion with a structural engineer. We were feeding off each other trying to work out the history and condition and issues for the client. It would have been easy to have missed the asbestos the owners had covered up.
Happy to chat
