CEE320: Seminar on Integrated Facility Engineering:

Introduction

Martin Fischer, Instructor

Big Idea: Design organizations and processes that make building projects sustainable. Use the computer to model, analyze, and visualize project alternatives.

CIFE Interactive (iRoom)

• Multiple screens• Multiple views

– Product, Organization, Process

– Function, Form, Behaviors

• Unified, yet flexible control– Multiple screens,

applications

7

Vision for Civil Engineering• Design

– Buildings, and– Corresponding processes and organizations

• For– Best use by today’s and future users

• With– Most efficient use of resources

• Considering– The triple bottom line: economy, ecology, equity

• Using computational methods– To model, simulate, analyze, and visualize the design and

its fitness for purpose• To

– Communicate design options to all relevant stakeholders,– And generate a clear execution plan

HOW: VDC Levels1. Visualization (assume manual integration)

•Routinely model and visualize all “expensive” elements of the product, organization and process

•Get input from all stakeholders when it matters•Manage with model-based methods• Incrementally enhance current business goals•Requires (possible with) project justification

2. Integration (computer based)•Product, organization & process models “interoperate”, i.e.,

notify, highlight, control, propagate, parameterize•Single data entry • Incrementally enhance business goals•Requires corporate multi-project support

3. Automation•Automated design and (CNC) manufacturing•Do high-quality work really fast all the time•Enables breakthrough project performance •Requires corporate multi-project support

Benefits of 3D/4D models on Paradise Pier• Preconstruction

– Unprecedented stakeholder involvement (400 in 2 months)

– More precise specifications

• Bidding– Bids within 2% of each other– Contractors understood scope and challenges

within 48 hours, could use rest of time to work on bid

• Construction– Contributed to reduced change orders (with

potential for further reduction)

displacement cooling mixed cooling

Am I selecting the right systems?

Virtual building model enabled CFD simulation provided the decision basis to select the more expensive displacement cooling system.

Method to Achieve Breakthrough Goals

Controllable factors - Visualization phase:– Modeled Scope: VDC models to build; factors to consider– Managed Scope: model-based management methods– Organization design strategy– Coordination activity– Prediction basis: computer-based models– Design versions

Controllable factors - Integration phase:– Integration focus: VDC models

Controllable factors - Automation phase:– Automation focus: design, fabrication tasks

àMeasurable process improvement– Field material delivery– Decision latency (Decision-making promptness) – Response latency (Decision-making no earlier than necessary)– Field-generated Requests for Information– Rework volume

à2015 Breakthrough goals
