Recipient


1. Technology Introduction

• 3D Laser Survey• Building Information Modeling

(BIM)• Virtual Simulation/Pre-

visualization• Clash Detection


3D Laser Survey

Point Cloud 3D Solids Model


Building Information Modeling (BIM)


Virtual Simulation/Pre-visualization


Clash Detection & Coordination

Where is the coordination

error?

Structural Plan

Mechanical Plan


• Ability to view, annotate, and measure• Capability to simulate phasing and

constructability• Requires all players to contribute• Free 3D file viewers include Navisworks

(.NWD) and Design Review (.DWF)


2. Relationship to Current Construction

Technology• 3D Shop Drawings• Direct Fabrication• Prefabrication

Direct Fabrication


Direct Fabrication


Prefabrication


3D Capable Trades

• HVAC• Plumbing• Structural Steel• Precast Concrete• Rebar• Steel Stud Walls• Curtain Walls, etc.• Millwork• Unit Restrooms• Laboratories


Relative Sophistication DisparityGeneral Contractors (Very Low to Low)

Engineers (Very Low to Moderate) Architects (Low to Moderate) Subcontractors (Varies, some extremely

high)

Maximize advantage of sophisticated players

Enhance process for Subs already using 3D Mentor less advanced members Integrated Project Delivery


3. Waste Reduction

• In Design• In the Shop• In the Field


Waste Reduction• 40% of US solid waste stream is construction waste.1

• Construction industry productivity falling while all others increasing.2

1. US Green Building Council

2. US Bureau of Labor Statistics


Waste Reduction in Design


Simulation & Virtual Prototyping

• Test Equipment Layout for Critical Spaces– Surgery Suites– Nurse Stations

• Test Sightlines• Test Processes• Test Aesthetics

Reduced waste of User Changes after construction.


• Reduced Document Coordination Effort• No duplication of effort between A/E• Real-time Project Metrics

Time for Efficient Design & Systems Coordination

Documentation Waste


Waste Reduction in the Shop

Efficiency Algorithms


No Part Duplication


Waste Reduction in the Field


Just-in-time Delivery


4. “Risk = Cost” Equation

• Increase in Architect’s Exposure

• Decrease in Contractor’s Risk• Decrease in Owner’s Risk• Reduced Risk for All = Reduced

Cost


The Big BIM/IPD/Lean Idea


Automatic Document Coordination

3D Systems Coordination

Virtual Building Simulation

Direct Fabrication

Project Delivery Improvement


Unknown Consequences Of Sharing BIM Information

Design Only Information In BIM ModelExtensive Pre-coordinationFabrication From Design Models

Increased Exposure to Risk

Increase in Architect’s Exposure


Reduced Coordination Errors Reduced Unknown Conditions More Efficient Workflow Cooperation & Collaboration Reduced Contingency

Increased Confidence & Reduced Risk

Decrease in Contractor’s Risk


Decrease in Owner’s Risk

Reduced Bidding Costs Due To Reduced Contractor Risks

Reduced Risk Of – Change Orders From Unknown

Conditions– Coordination Changes– Fighting Among AEC Entities

Reduced User Changes Due To Better Pre-visualization And Planning


Reduced Risk for All = Reduced Cost

Architect’s Exposure However

Architect’s Risk
