I am not a surveyor nor an architect but I am carrying out a buildings defects survey in advance of an expert witness architect coming to do a building defects report.

This architect has said he won't find every fault in a two/three hour survey and he wants me to shortlist faults for him to look at before his site visit.

I have found loads of faults but what in your opinion are the most common and serious faults cowboy builders make? I am sure I have not found everything yet.

This is a masonry barn conversion but new build faults are probably just as relevant.

I do a lot of pre-purchase work through estate agents, surveyors and insurer`s. I find that if they F%$£ up the cosmetic stuff then the rest will be b$ll%^$.

In your case there has to be line drawn between spending ££££ on getting expert witness/statements and spending £££ on putting it right.

Unfortunately most cases require that you get an expert from each trade plumber/spark/roofer but trades such as the one i have the pleasure of working in don`t have a single body to oversee things.

Did you have the works carried out or did you inherit the job?

I have inherited the job.

Everything needs to be fully checked right down to the foundations.

seems like your expert wants you to do his work for him. I have had surveyors assume that dpc are felt when they are two layer slate, dado rail supposedly installed 'probabably to hide damp' and 'amatuerish wainscotting prossibly to hide poor or defective plastering'.In actual fact the wainscotting was top quality tgvand b douglas fir at £6.00 a metre! You will note the choice of words though... probably....possibly... not definately or surely. If your expert cant find the majority of faults as you have he should take up a new career... any suggestions? ps have recently had to condemn a basement flat with about 70 contraventions to building regs. Lady was not pleased having spent some £20,000.00 on having it furbished, only to be told it all required ripping out and redoing, and that the work had affected the structural stability or the rest of the property as they had excavated below the founds.

I found more wall tie failures today and areas where the slab is only 3"-4" thick instead of 6"!

It seems that it is only the foundations left to condemn!
