BD2 uses basic matrix structural analysis formulation combined with time-dependent material properties, to carry out a Time Simulation of a structure under construction. During this process, all stress conditions are checked at every construction step and in service.

BD3 provides a 3-dimensional environment in which it performs a time simulation of construction stages for concrete pre- and post-tensioned structures.

The MC3D geometry control program Is used to monitor the casting operations and establish “as-cast” curves step-by-step to verify that the actual superstructure geometry is in close agreement with the geometry described in the design documents.
