All the risks and uncertainties are put on the door of the suppliers / contractors. One should realize that although the surveying and mapping process never costs more than 1 or 2 percent of total budget, the same is not true when it comes to the time taken for the mapping project. The fact is that many projects are delayed just because the survey data of right quality and proper map was not made available to the engineer / planner.
