AEC case studies
Verified construction sequencing examples demonstrating phasing logic, load transfer validation, and staging constraints in live projects.
Sequence validation in fit-outs often hinges on coordination between structural integrity and temporary support systems. For example, a high-rise lobby retrofit required staging floor demotion without halting tenant operations. By modeling each lift shaft insertion in time sequence, designers confirmed that intermediate shoring loads stayed within existing beam capacity. Solver settings used quasi-static stepping with small time increments to catch subtle interference.
Demolition phasing benefits from 4D modeling to visualize mass haul paths and prevent structural imbalance. In a historic building remodel, partial floor removals were staged over three weeks, with each phase checked for lateral drift under gravity only. The simulation allowed adjustment of tie-beam install timing to maintain stiffness thresholds. This reduced field change orders by highlighting ahead of time where temporary cross-bracing was needed.
Temporary works like formwork or falsework benefit from simulating installation sequences under live site conditions. A bridge abutment project modeled crane swing arcs and staging access lanes to ensure clearance during form erection. Timing intervals included 15-minute buffer zones for rigging adjustments, avoiding overruns. Solver settings used event-triggered steps, activating each support only when preceding elements were confirmed stable.
