8. Estimation Tool
Improves Coordination
Effective Marketing Presentation of
Construction Approaches
Identifies Potential Construction Conflicts

9. Reduces Errors Made in Design Phase
Helps Clients & End Users Visualize
Product
Helps Owner Make Informed Decisions
Provides Material Inventory for Owner

10. REVIT® From AutoDesk®
• REVIT Structure – M&N (Gaul & Chris Greene)
• REVIT MEP – MMM Design Group
• REVIT Architecture – MMM Design Group
Compatible with AutoCAD, 3ds Max, &
Google SketchUp
• Import/export .dwg files
• Import/export 3D model

11. Model Developed after 35% Submittal and
was Submitted with Final Submittal
Design
• Utility Conflicts
• 3D Rendering – M&N (Jeanah Bauer)
• Owner can Visualize Final Product

12. Construction
• Contractor can Visualize Construction
• Scheduling/Phasing
• Equipment Maneuvering
NAVY
• Inventory
• Inspection – catalog damages/repairs
• Internal Marketing & Discussions
• Identify Utility Conflicts for Retrofits

13. Structural – Piles, Pile Caps, Deck, etc.
Civil – Stormwater, Grading, Paving
Mechanical – Water, Sanitary, SY Utilities
Electrical & Communications
Architectural - Buildings

14. Pier 5 – New Construction

15. Hitchcock Street – Renovation

27. View to Show Pier Supporting Utilities

43. NAVY & SKANSKA Happy with Product
• Reduction in RFIs
• Reduction in Turnaround Time on RFI’s
M&N’s Efforts
• 635 Man Hours (includes converting Revit Model
to Uniformat AutoCAD file Requested by NAVY)
• $61,795 ≈ 1.2% of overall fee.

44. Offshore Heavy Weather Mooring
Structure
• Piles Battered Inward to Reduce Obstructions in
Ship Channel
• Concern with Pile Day Lighting from MLLW to -20’
MLLW
• Possible Conflict with Mooring Anchor Plate
Model was an Independent Effort
• Not Requested by NAVY, & not submitted
• Developed as a Design Aid

50. Mooring Anchor Plate in Vicinity
• Cut Section at Elevation of Mooring Anchor Plate
• Export Section to AutoCAD
• Insert Contractor RFI Drawing into Section View
Identify Conflicts with Plate
Answer RFI & Adjust Design as Required

52. BIM Has Been Helpful By:
• Improving Coordination
• Identifying Potential Construction Conflicts
• Reduction in Errors Made in Design Phase
• Help Visualize End Product
Potential Future Uses of BIM for M&N
• Design Build Projects (Most Contractors are BIM
Ready)
• Projects with a High Possibility of Conflicts
• Sustainable Design
• Cataloging Deficiencies in I&R Work (can be done
in conjunction with GIS)
