@schmetterlich In my view, "penalizable" means "subject to penalty", and it should not be confused with "penalizado", which is already a fact, something that has happened, a penalty already applied. I fear your Spanish source is poorly written und might be therefore "subject to a wrong interpretation" :-). Be careful.

The next paragraph states the following: Por el lado del contratista, se requería flexibilizar las fechas de los hitos intermedios penalizables, puesto que no calzaban con la correcta y eficiente planificación de los procesos constructivos, esto sin sacrificar la fecha fin, por tanto debía existir una colaboración mutua.

Maybe "once hitos parciales penalizables" refers to 11 milestone dates whose non-compliance was sanctioned?
