Hi, A piece of information I thought some might find useful. I recently enquired about an RSJ calculation for a roof span having been advised to get a structural enginner at a cost of anything up to £425 + vat. I contacted Corus who put me intouch with Catnic. Catnic will work out your calculation free of charge, however there is a charge of £75.00 for a certificate if you need it for the building regulations - thats fair I think.
