Given the continuously tightening fees, project controlling within planning offices is becoming more important. No engineering or architecture’s office can avoid the permanent verification of its economic efficiencies and counteract the imminent aberrations. Therefore it is necessary to be able to edit all decision-relevant data like costs, invoices, working hours etc, according to all possible conceivable criteria and to analyse it. Only a permanently updated overview of the project helps you to recognise saving potentials and to find out where the work has been done notably efficient.
