01 History Lesson

"Those who cannot remember the past are condemned to repeat it"

Interchangeable Parts

• Popularized the idea in late 1700’s

• Won Contract to provide 10,000 Muskets to US Military

• Gave famous demonstration to John Adams and Thomas Jefferson

Muskets Were Unique

• Cost more to Make

• If one part did not work,it was a problem

One Part is a Problem

• Cost more to Make

• If one part did not work,it was a problem

Limiting Factor

Small Problems become Big Problems


• Custom Parts for many

Shared Parts

• No Customization

• Cohesive Unit

03 What is IFC?

IFC is a Software Standard

Industry Foundation Classes (IFC)

ISO 16739

IFC uses 3D Models

Industry Foundation Classes (IFC)

IFC Candidate Standards

IFC RoadCandidate Standard Status: Published

The focus of this phase is to implement and validate the Candidate Standard IFC 4.3 and bring it to the status of a Final Standard and publish it as an ISO Standard. Phase 1 included the “Requirements Analysis Report” which was published and the delivery of the schema extension Candidate Standard.

This phase is a Call for Participation to the software vendor community to implement and test the standard against a specific set of use cases.

IFC BridgeCandidate Standard Status: Published

The ifcBridges team delivered this Standard and as part of the project execution plan were able to deliver against these collective team goals:• WP1 – Common Definitions and Data Requirement• WP2 – ifcBridge Extension and MVD Development• WP3 - bSDD• WP4 – Roadmap and next phase• WP5 – Deployment and Dissemination

The project is now complete and is widely available for use.

04 IFC in Practice

2020 buildingSMART Award Winner Innovation in Client Leadership

Norwegian Public Roads Administration“Machine Readable Norwegian Classification Manual for Bridge Registrations”Norway

Open standards enabled:

Open machine-readable manual

Bridge designers used IFC software

Developed using Linked Data and semantic web

Integrating ontologies was key

ifcOWL, IFC 2x3, IFC4

“To use of openBIM® and other open standards is the very essence of this

project”

Elin Dalen-Rasmussen, Norwegian Public Roads Administration

2020 buildingSMART Award Winner IFC for Design: Panama Canal 4th Bridge

2017 buildingSMART Award Winner IFC Model for Operations & Maintenance


First “bridge with brains” usin g embedded senors

Gov. Mario M. Cuomo Bridge3.1-mile crossing of the Hudson River with eight l traffic lanes, dedicated bus

lanes and a shared-use pedestrian/bike path on the northern span. Owner: New York State Thruway Authority (NYSTA)Design Consultant: HDR Design-Build Contractor: Tappan Zee

• Connected to Construction Documentation (specifications, DWR’s, NCR’s)

• Models from 4 different software applications

• Over 1 million connections between the 2D documents and the 3D model

• IFC format enabled the connections to be automated

2020 buildingSMART Award Special MentionTeam Collaboration using openBIM®


project”


IFC based standards enabled team collaboration and project information to be shared by:

• 36 BIM users across 8 different companies

• 20 models from 5 disciplines using 6 different software applications

• Federation of a total of 1,370,000 IFC structural objects.

2020 buildingSMART Award FinalistResearch Project: IFC Model Based Workflows



project”


Research Summary

• Paper-less project

• Model-based design to enable digital workflows

• Limited number of drawings

• Specification of work and cost estimation were automated

• 4 design programs linked to a cost estimation software based on IFC

• 50% time reduction, especially at revisions

2020 buildingSMART Award WinnerAsset Management Open standards enabled:

Over 100 disparate models

successfully geo-located,

exported to IFC

250,000+ elements modelled

within the terminal

Mandated openBIM delivery

requirements for Native and

IFC models for AIM

requirements

Improved productivity

Auckland AirportAuckland Airport maps its future with openBIMNew Zealand

“openBIM enabled us to do more with less by being free to work between multiple tools as needed, without having to work within the constraints of one software”

Karl Fitzpatrick, Auckland Airport

“The idea that IFC was the BIM deliverable method became agreed by the client due to

its efficiency and final on-site savings”

Véronique Remande, ICOS Groupe

• Model was contractual deliverable

• Minimal 2D Documents for 3rd parties

• Bill of Bars generated from Bentley OBM

• IFC export sent to Fabricator
