VDC definition

Virtual Design and Construction (VDC) is the use of multi-disciplinary performance models of design-construction projects, including the Product (i.e., facilities), Work Processes and Organization of the design - construction - operation team in order to support business objectives.

to be the world's premier academic research center for Virtual Design and Construction of Architecture - Engineering - Construction (AEC) industry projects.

Virtual Design and Construction (VDC) is the use of multi-disciplinary performance

models

of design-construction projects, including the Product

(i.e., facilities),

Organization

of the design - construction - operation team and Work

Processes

in order to support

business objectives …

to support exceptionally reliable engineering and management processes to plan, design, construct and operate sustainable facilities

Plus-Delta of Civil and Environmental Engineering

Provides fixed physical assets and wealth of society

High global demand for infrastructure and housing

Opportunity to impact global climate challenge significantly

Low productivity

 compete with other ways to spend $

High energy use and rising energy costs

Structural reliability << societal need (Chile)

VDC elements

Slide by Martin Fischer

Slide12

VDC has a management focus

Design of

Product

: classic focus of engineering design and analysisFirst object-oriented CAD models at StanfordOrganization: Necessary because of complexityEmerged because of influence of Ray LevittProcess and production management

Necessary because projects live over time

Emerged from discipline of CEM, started at Stanford

Slide13

Coordination latency (days)

What they are: metrics, target and measured values, status (

)

So what: Bloom et al.

Latency of different teams

Management objectives and metrics

Rework volume

:

Cost

: >= 95% of budgeted items within 2% of budgeted cost

Prediction basis:

> 80% of predictions founded

*Function (quality) conformance (%):

>= 99%

Quality - Delivered Scope

: 100% satisfaction by

POE

Design versions

:

2 or more >= 80%

Schedule conformance (%):

>= 80%

*Sustainability: >

75% better energy, water, materials, than 2002, profitably

Staff trained in VDC:

>=

4/project

Cost conformance (%):

>= 95%

Globalization

: >= 50% of supply and

sales

Outcomes: major milestones

Production management: short intervals

Product models - BIM

What it is: Objects with attributes

Building Information Modeling (BIM)

 - process involving generation and management of digital representations of physical and functional characteristics of places. Building

Information Models

 (BIMs

) - files which

can be exchanged or networked to support decision-making about a place.

Production management

What it is: transformation

of

operational inputs into "outputs" that, when distributed, meet the needs of customers.Short-interval“pull”LeanOriginsLean community

Slide22

Complexity

Definition: High uncertainty and knowledge required exceeds that of any individual, e.g., construction (flight/surgical) team; design structural

Other task

types: Simple: many people can quickly learn to do the workSpecialized: large amounts of training need to learn to do the (virtuoso) work, e.g., Master-builder (

pilot/surgeon)

Reliability management is a

requirement

in situations with

complexity, and VDC can help

Implication: complexity inspires the management, organization and process focus of VDC
