model (Appendix E). This information was used by LPR to design the rigging for the
complex lifts on the project (Figure 23).

Mortenson’s 3D digital model, built from design-team models, included steel, concrete,
ductwork, piping, conduit, fire sprinklers, scaffolds, temporary steel, falsework, crane
locations, even rigging frames for steel lifts. It was used during construction for
development and coordination of shop drawings, generated in 2D for field use.
Mortenson’s 4D model, which added the element of time, was used for visualization and
construction sequencing – for virtual prebuilding as a way to educate subcontractors and
anticipate and eliminate field problems (Post, 2006b).
