Main 2 root causes of low productivity are,

• lack of interoperability• lack of collaboration

Essential Definitions.

• what is openBIM?openBIM simply means working with BIM using open Standards.

• Well, what are open Standards?

• Open BIM supports a transparent, open workflow and allows project members to participate regardless of the software tools they use.

• OpenBIM speaks in the same language for all of the processes in life cycle of the project.

• Open BIM provides enduring project data for use throughout the asset life–cycle, avoiding multiple input of the same data and consequential errors.

• All of the software vendors can participate in life-cycle. We have IFC, right?

• Project members can decide about their software upgrades independently from their peers in different project.



• buildingSMART

buildingSMART, formerly the International Alliance for Interoperability (IAI), is an international organization which aims to improve the exchange of information between software applications used in the construction industry.

SESSION KEY POINTS

What is IFC?The Industry Foundation Classes IFC represent an open

specification for Building Information Modeling BIM data that is

exchanged and shared among the various participants in a

building construction or facility management project. IFC's are the

international openBIM standard.

The IFC schema specification is the primary technical deliverable

of buildingSMART International to fulfill its goal to promote

openBIM®.

The schema specification can describe how a facility or

installation is used, how it is constructed, and how it is operated.

IFC can define physical components of buildings, manufactured

products, mechanical/electrical systems, as well as more abstract

structural analysis models, energy analysis models, cost

breakdowns, work schedules, and much, much more.

How to create IFC































Model View Definitions (MVD)

A Model View Definition (MVD) is a subset of the overall IFC schema to describe data exchange for a specific use or workflow, narrowing the scope depending on the need of the receiver. An IFC View Definition, or Model View Definition, MVD, defines a subset of the IFC schema, that is needed to satisfy one or many Exchange Requirements of the AEC industry.




Official buildingSmart MVD’s for IFC 2×3

• Coordination View – spatial and physical elements for design coordination among the architectural, structural, and installation sectors (MEP).

• Space Boundary – identification and export of additional space boundaries (polygons defining the extent of space contact with directly adjacent surfaces (such as walls, floors, ceilings) and openings). It can be used for building energy analysis and Quantity take-off.

• Basic FM Handover View – a basic view providing data for facility management (Facility MAnagement). Transfer of model information to CAFM (Computer Aided Facility Management) and CMMS (Computerized maintenance management system) applications.

• Structural Analysis View – a structural analysis model, developed in a structural design program, sent to one or more structural analysis programs.


buildingSmart officially defined two MVDs for IFC4

• Reference View – suitable for workflows based on reference models, with unidirectional exchanges. Any modification of the model must be processed by requesting a change to the original author.

• Design Transfer View – supports the editing of interconnected elements: insert, delete, move and modify construction elements and spaces, with a limited scope to parametric exchange.

Information Delivery Manual (IDM)

• What is an Information Delivery Manual (IDM)?

IDM is a technical document (physical or digital) that describes what information is required, in what order, when should it be delivered and who is responsible for providing it.

• Are there standards for the production of an Information Delivery Manual?

Standards for IDMs can be found in:

• ISO 29481-1:2016 Building Information Models - Information Delivery Manual - Part 1: Methodology and Format

• ISO 29481-2:2012 Building Information Models - Information Delivery Manual - Part 2: Interaction Framework

https://www.iso.org/standard/60553.html

https://www.iso.org/standard/55691.html


• Structure of IDM

1. Use Case. It is a combination of the purpose of the information delivery, business need, involved actors and their roles and external aspects, that need to be considered within the delivery.

2. Process Definitions. These are represented in the form of different types of process and/or interaction maps.

3. Exchange Requirements (ER). It present in detail the geometrical and information requirements of the delivery. Even though these properties are presented in non-technical terms, they need to be specific.





• BIM Collaboration Format (BCF)

The format was created on the basis of IFC, but with additional capabilities added for the needs of communication, The new feature is the exchange of only information containing a reference to a model element (via GUID), a description of the problem and optional additional files, instead of replacing entire IFC models.

BIM Collaboration Format (BCF)




▪ Design phase

o Documenting quality assurance / quality checking (QA/QC) items of BIMs

o Identifying design coordination (clash detection) issues between domain BIMs

o Annotating design options, object substitutions, and material selections

▪ Procurement phase

o Bidding coordination items and clarifications

o Cost and supplier information for objects, assemblies, and/or systems

▪ Construction phase

o Quality assurance / quality checking (QA/QC) records of installations vs. BIMs

o Tracking availability of items/materials and coordinating substitutions

o Collection of last-minute information for handover to owner/operator as part of the COBie deliverables

▪ Operations phase

o Notations to handover models as changes are made to the facility and its many elements during occupation

o Owners notes about needed upgrades

buildingSMART Data Dictionary (bsDD)

• What is bSDD?

The buildingSMART Data Dictionary (bSDD) is an online service that hosts classifications and their properties, allowed values, units and translations. The bSDD allows linking between all the content inside the database.



• How it is used?

• bSDD is used to uniquely identify properties independent of which format the property resides is.

• bSDD is used for language translation of property descriptions enumerators and values

• bSDD is used for mapping between various classification systems


• How bsDD can help?

• Agreement on Common Terms

• Multilingual Translations

• Assigning each property a unique

• Helps finding building products

• Helps selling building products
