What Is BIM?What Is BIM?

DefinitionDefinition• BIM is the move from analog to digital

design and construction. A model-based technology linked with a database of project information - AIA

• Construction is the only industry that does not/cannot test a design before production

2D vs. 3D2D vs. 3D

4D Example4D Example• The Sundt Corporate Office

44thth Dimension - Time Dimension - Time• Each element in model tied to CPM

Schedule• Construction sequence can be

simulated showing conflicts between trades

• Play “What if?” game with model to find more efficient construction path - saving time and money

• Once construction begins model used to track construction progress

5D5D

• Each component of the BIM tied to the Cost Estimate

Model ChangesModel Changes

• The ability to change the model is strictly limited to those who are responsible for changes to that portion of the model

• A precise audit trail can be maintained

BenefitsBenefitsandandAdvantagesAdvantages

Benefits & AdvantagesBenefits & Advantages

• Clash Detection• Faster Construction Time• Streamline

Delivery/Fabrication• Better Performing Facilities• Fewer Claims• Real Time Value Engineering• User Understanding – 3D

Visualization

ChallengesChallenges

ChallengesChallenges• Lack of standards for organization

and format of data contained within the model

• Contracts/Delivery Methods– Defining responsibility– Allocation of Risk– Ownership of data– Insurance/Surety/Bonding

• Interoperability• Fear of change• Initial investment costs• Learning curve

Challenges – For DesignersChallenges – For Designers• Change in culture & work flow

– Work is divided up by major building elements in lieu of by drawing sheets

– Decisions are made earlier as to materials, specifications and quantities

First StepsFirst Steps

• Get Senior Management involved to ensure leadership support

• Dedicate someone to the effort – BIM Champion

• Prepare a BIM plan – keep it simple and specific

Learning CurveLearning Curve

• It is generally accepted that there is an initial cost and loss of productivity while obtaining the necessary resources as firms go through the initial learning curve.

• Those firms who have made it through this initial learning curve (on average between 6 and 18 months) experience the benefits.

Question: Yesterday vs. Question: Yesterday vs. TodayToday• Yesterday: When & why

adopt BIM?

• Today: How do we effectively deploy it?

Software & Training CostSoftware & Training Cost

• Design Software $3,200.00 +/- per user

• Navisworks $8,000.00 +/- per copy

SummarySummary

• Use of BIM is leading to a revolution in project delivery and facility maintenance.

• The traditional tri-party approach to design and construction will, over time, be replaced by “Integrated Practice” and collaboration
