order to elaborate the auxiliary WF, the unit WF or the complex unit WF in the same
way that the AP, PU, PUC were elaborated, the quantities of project material for
each one of the cases were applied, how in the price table of an economic budget,
one starts from the simplest units to obtain the most complex units. An example of
unitary WF is given in Table 13: m
3 of concrete: HA-30/P/20/IIa + Qb in floors and
foundations. Finally, by applying the project’s measurements to the unitary WFs, the
project’s WF results are obtained.
