During the bridge repair project (in the execution phase), the customer (town hall) asked for a change of parameters in comparison to the original requirements. It is a matter of increasing the fencing of the bridge on both sides in response to a request by a newly elected city mayor. He, in his election campaign, promised he is going to make the prevention against suicides by jumping from the bridge. However, the contractor does not want to change the project scope, because that would mean to rethink all the parameters of the bridge and the entire project. That would significantly slow down or even delay entire project.
