For example, could the person giving the orders, the architect responsible for the job, restrict the scope of the project to such an extent that there would only be one bidder capable of doing the work, as you were mentioning earlier? If that contractor is the only one capable of doing the work, then he or she could set conditions, impose specifications or money issues, to such an extent that there would be no way of avoiding fraud.
