Tochnog Professional offers many options for staged analysis of complex building processes. Elements can be activated at times of choice, the material of elements can be changed during the building process, geometrical regions can be activated or de-activated, stresses can be set or reset or multiplied by specified factors to model pressing, beams and interfaces are available for structural parts, excavations can be done for elements or regions with elements, special post processing allows for output of forces and moments in isoparametric elements, etc.

The first picture here shows a 3D building process, whereas the second picture only displays the structural parts of the building process. Calculation courtesy of Zueblin AG, Germany, http://www.zueblin.de.
