WP2: Building Information Modelling and Interoperability Workshop – [email protected]

About BIMBuilding Information Modelling (BIM) is the process of generating and managing digitaldata about a facility data during its life-cycle. The process produces the BuildingInformation Model (often also abbreviated as BIM) which covers three-dimensionalgeometry, spatial relationships, geographic information and component properties for thedesign, construction and operation of a building. BIM serves as a sharable repository whereinformation is linked and over time encompasses everything about the facility.

Building Information Models are created primarily by architects and engineers for designand analysis. But why stop there? BIM can be a source of key information for manyactivities during the life-cycle of the facility. Updating the model with commissioned data,and linking it with operation and maintenance information, can help with the facilitymanagement process, optimize energy performance, support emergency preparedness andmuch more.

BIM is not just one model, technology or standard. It is about the collection and digitalembodiment of data throughout the entire life-cycle of a facility with emphasis onintegration and interoperability of the data and its usage.

Insights into the future of building design,construction and management BIM isrevolutionizing the way project stakeholders usedigital data created by different participantsthroughout a building’s life-cycle. This new processis quickly becoming recognized for the value itbrings to any project.

Challenging the AEC-FM Industry: Interoperability, BIM and Collaborative Workspaces

Building Information Modellingis one of the most promisingdevelopments in the architecture,engineering and construction (AEC)industries.With BIM technology, an accuratevirtual model of a building isconstructed digitally.When completed, the computer-generated model contains precisegeometry and relevant data neededto support the construction,fabrication, and procurementactivities needed to realize thebuilding.[Eastman C., et al., BIM Handbook ... p 1]


Challenging the AEC-FM Industry: Interoperability, BIM and Collaborative Workspaces

Interoperability identifies the need topass data between applications, and formultiple applications to jointly contributeto the work at hand [Eastman C., et al., BIMHandbook ... p 66]

Issues in Interoperability for AEC-FM

Traditional approaches to sharing project information via file exchange using formatssuch as .dxf, .dwf, .dwg and .pdf do not transfer the appropriate levels of objectintelligence from one model to another.

New approaches which strive to address the need to exchange more intelligent projectdata include necessarily new formats.At present, data exchanges between two applications are typically carried out in fourmain ways:• direct;• proprietary links between specific BIM tools;• proprietary file exchange formats, primarily dealing with geometry; and• public product data model exchange formats like IFC, XML-based exchange formats .


Interoperability between 3D Parametric Model and Energy Performance Simulation

Energy analysis programs, such as Ecotect, IES<VE>,eQuest, Energy Plus, Design Builder, HEED etc havetraditionally been used to study the energyperformance of buildings in order to design moresustainable and energy efficient buildings.Programs may range from simple, user friendly,free tools to extensive, sophisticated programs thatneed specialized knowledge and are used bybuilding engineering firms. The range ofapplications include simulations, load calculationsand thermal, solar, lighting, acoustic, ventilation,computational fluid dynamics (CFD) analysis as wellas a host of other functions. Most of theseprograms support 3-D modeling functions, andmay allow the engineering/design team to be ableto import drawings from CAD or other drawingformats (like Revit Architecture).

BIM standardization in the construction industry

At the present time BIM and Interoperability are regulated by specific standards ISOsuch as:- ISO 12006-2:2001 Building construction - Organization of information aboutconstruction works - Part 2: Framework for classification of information;- ISO 12006-3:2007 Building construction - Organization of information aboutconstruction works - Part 3: Framework for object-oriented information;- ISO 22263:2008 Organization of information about construction works – Frameworkfor management of project information- ISO 29481-1:2010 Building information modeling - Information delivery manual - Part1: Methodology and format- ISO /TC 59/SC 13: Organization of information about construction works.


A significant role on standardization is taken on by the OmniClass ConstructionClassification System (known as OmniClass™ or OCCS), which scope is to encompassbuilding objects at every scale through the entire build environment, from completedstructures, vast projects, and multi-structure complexes to individual products andcomponent materials. It is designed to address all kind of building (vertical andhorizontal, industrial, commercial and residential). It also addresses actions, people,tools, and information that are used or take part in design, construction, maintenance,and occupancy of the buildings. The approach of OmniClass based on the building lifecycle is particularly important in a field such as construction, traditionally focused onorganizing segments of information, one portion and one discipline at a time.

Innovation

Several studies in recent years show that tedious manual data input for building energyperformance and consumption simulation diverts time and resources from productivesimulation runs, also because of the fact that data defining a building, its heating,ventilation and air conditioning (HVAC) and lighting systems and its expected pattern ofuse and operating schedules, is managed by different and non-interoperable software.By utilising BIM as a data source and interoperability as format exchange for energyanalysis, the data input will be more efficient and the existing data more reusable.

Buiding Information Model for

Architectural design

Architectural design begins with preliminary building massing models, continues with building core and shelldesign, the layout of interior spaces and construction detailing. The development of the architectural BIM modelprovides the basis for coordination of all other disciplines (i.e. mechanical, electrical, structural, plumbing)
