Documentation Advantages – Rapid Visualization

• Integrated visualization and documentation process

• Changes to model automatically updates project documentation


Documentation Advantages – Integrated Information

• Inherent Information in model objects create quick automatic schedules

Program Design Validation

Too small OFFICE spaces. Area of the spaces is 95.48 sq ft, when the required minimum area is 125.00 sq ft.

Model Based Layout

Combined model reviewed with structural engineer, layout team, and detailers.

Points exported from model to total station for layout.

As-built information overlaid for verification prior to concrete pour.

Early field verification to accelerate release to fabrication


Model Based Layout

Trades: Mechanical, Plumbing, Electrical, Fire Protection
