The same applies to the calculated results. Program is really easy to use. Firstly you study your tender, collect all the drawings and standards. From these documents you can decide how to set up the Price Master tender. You decide how to divide your take offs.
More details mean more work but also more meaningful results.
It is possible to enter all your take offs using one DRWG, Line number and Area, but it is not advisable. The next step is to find the line classes for the tender. Some clients make this work easy by standardizing all their piping. If you are not so lucky, you can create your own. This is not difficult but needs some minor planning.
