Do sign up for student membership of RICS and CIOB - that should give you access to some things.
If you still want something I think Real Estate Concepts (Jowsey et al) is a really good starting point. OK - I know it has real estate in the title but essentially you get a chapter on everything - a bit of law, a bit of construction, a bit of building surveying, quantity surveying, development etc.
I am looking into starting preparing for a bsc in building surveying this coming September and I am looking for books to read to better prepare myself for the part time course. Have you any suggestions or guidance you could provide to support me further with my preparation activities
