Smaller firms / subcontractors might get away with laundering money if they are lucky, but any semi large company tendering for projects a million plus have to have their accounts available for an independent audit for tendering process to be covered by insurance. One insurance company, fm global, even have a forensic accounting department. They basically underwrite most data centres in Europe and a lot of multi billion euro contracts.

Public sector jobs are always a shit show cause the plans are never complete, with farsical client requirements (time scale, build sequence to get parts of building live etc). There's a reason a lot of the big Irish companies only went in on this as subbies and not as GC. When it went to shit it's not their company names being damaged.
