The Next 45 Minutes What Are BIM, Lean and IPD?

How Are They Tied Together?

Should You Care About Any of These?

How Can You Get Up-To-Speed?


3/45

What Is BIM?

BIM = Building Information Modeling

Software simulation of design, construction, and facilityoperation

Virtual Design & Construction BIM is VDC + Analysis, Operations, etc.

BIM is a processnot a software! (10% technology /90% sociology)

Data-Rich Computer Model Can truly be a collaborative process, which means

interdependencies are created

What Is BIM?

BuildingInformationModeling

(BIM) Virtual Time Machine

Integrated Project Data

Data Sharing

Enhanced Visualization

Coordination

Collision Detection

Linked Parametric

Information

Process Collaboration

Interoperability

Digital

Intelligent

Object-Oriented

Data-Rich

There are so many definitions!


5/45

Definition: 3D modeling refers to thecreation of three-dimensional objects that aredefined mathematically and geometrically

3D (L X W X H) Project Geometry.

Visualization & Design Assist

Collision Detection & Coordination

Constructibility Review

Digital As-Built Record Documents

Size, location and intelligent attributes of objects.

Objects may be linked to each other to form aspatial relationship.

Paper documents generated from 3D Model

Models from different disciplines may be linkedtogether to form a federated model.

Embedded Knowledge

Quantities of all materialslinked directly to databases

Data-Rich Model enablesaccurate quantity survey ofmaterials

Cost implications of designchanges can be understoodin real time


9/45

BIM TerminologyCollaborative BIM Model is developed collaboratively with the owner,design team, construction team, and others allcontributing.

Non-collaborative BIM Model is not developed collaboratively, and the

construction team must develop its own model

based on the information provided by the design

team in construction documents. Contractor hasgreater control over information in model.


10/45

Think of spatial coordination as a spatial spell check

for a building's components: Equipment; Fixtures; Pipes; Ducts; Conduits;

Structural Members; Architectural Features

Get started early because it can take a lot longer thanyou anticipate

Get input from all trades early

Consider running meetings live

It is going to be a challenge getting a group of 10-15strangers to interact & collaborate

Spatial Coordination

5D BIM provides early reliable and defendable costing,backed up from a commercial database or your companys

own historical cost database.

Benefit: Predict Costs Early

Benefit: Evaluate Alternatives

Design alternatives can be completed to provide real-time costcomparisons of building envelopes, MEP systems, structural systems,levels of interior finish out, alternate sites, different parking ratios, and

landscaping proportions.

14/45

Getting Started with BIM

Understand the advantages that BIM would have foryour firm

Understand where BIM is in your market and what yourcustomers are doing

Select the right BIM software based on compatibility: Internal needs and preferences

Other software used

Current and future customers and market

Get training for key people Re-engineer internal processes and procedures to take

advantage of this new tool

What to Look for in a BIM Tool Simplicity

Functionality

Interoperability/Collaborativeness

Vendor Longevity

Support/Training

Environment


16/45

Barriers/Challenges Technology, Software, Staffing

Staffing? Learning curves?

Interoperability costs?

Paradigm Shift

Different way of doing business

Traditional contract terms tailored to paper-based practices

Earlier collaboration necessary

Legal Concerns

Who should pay for the model?

Who owns the model?

Who is responsible for accuracy of the model?


17/45

Guidelines to Consider

Motivation Drives Use of BIM

BIM doesnt change contractual roles

Can facilitate more collaboration

Supportive environmentwithout it, you wont get far

Build critical mass of BIM knowledge

Collaborative effort


18/45

Why Use BIM? Improve customer experience

Enhance productivity

Optimize schedule

Provide effective collaboration


19/45

Origins of Lean Production Manufacturing philosophy which shortens the

timeline between customer order and productshipment by eliminating waste

Modeled after the Toyota Production System(TPS)

Lean Construction is not Lean

Production


20/45

Origins of Lean Construction Transformation, Flow and Value

Theory developed to understand production inconstruction

Workflow Reliability

Real-world efforts at productivity improvements andweekly planning failures


21/45

Last Planner System

LPS is:

An outcome product of LEAN Construction

Starting with milestones & working backwards

Getting team member buy in

Optimizing the overall project


22/45

Lean Benefits

Lower Costs

Fewer Delays

Better Safety

Less Surprises

Less Waste

Constructor / Designer / Owner Satisfaction


23/45

Benefits of Team Buy-in

Develop Realistic Schedules

Take Ownership

Make Better Planners Proactive not Reactive

Integrating BIM in Pull Planning

Pull Planning Session


26/45

What is Pull?

This means no one upstream should producea good or service until the customer

downstream asks for it. Products andservices are created only on demandinother words, dont make it until the next guy

needs it.


27/45

1. Transportation (moving products that is notactually required to perform the processing)

2. Inventory (all components, work in process

and finished product not being processed) 3. Motion (people or equipment moving or

walking more than is required to perform theprocessing)

4. Waiting (waiting for the next production step)

Types of Waste (Muda)


28/45

Types of Waste (Muda)

5. Overproduction (production ahead of

demand) 6. Over Processing (resulting from poor tool or

product design creating non-value addedactivity)

7. Defects (the effort involved in inspecting forand fixing defects)

8. Underutilization of Resources

(not following up or implementing

ideas or suggestions)

33/45

A New Way of Planning

Traditional Thought

Leadershipdictatesdirection

Planningis partitioned bytrades/disciplines and is

linear. It is predictive andgenerally fixed, settingparameters for management

Managementcontrols areinflexible, autocratic -

processes are fixed andmeasures are isolated andgenerally historical

Lean Thought

Leadershipfacilitatescollaborative direction

Planningis collaborative,project based and seeks tointegrate efforts to eliminatenegative iterations. It learns asproject evolves

Managementdevelops anetwork of commitments to

implement plan, evolvesintelligence, measures areintegrated and proactive


34/45

Summary Lean Construction

Improves how work is managed in planning,designing, constructing, operating, and usingbuilt environments

Offers three opportunities for implementation,depending typically on the project procurementsystem used (DBB, CMAR, DB, IPD, etc.)

Is learned by doing Is adopted by eliminating waste, followed by

using the LPS


35/45

Integrated Project Delivery (IPD)

Definition: IPD is a project delivery method

distinguished by a contractual agreement

between a minimum of the owner, designprofessional, and builder where risk and rewardare shared and stakeholder success isdependent on project success.
