Critical Issues and BIM – NIBS buildingSMART alliance conference – January 7-11, 2013

The fundamental day-to-day business processes of the Engineering, Construction, Owner, and Operations sector are changing.   That said, major cultural change must occur in order to make significant progress.   The efficient life-cycle management of the built environment will not happen until change management is accelerated.   Efficient construction delivery methods (IPD – integrated project delivery, JOC – job order contracting), cloud computing, and BIM are all integral components.

Symposium Name:   The buildingSMART allianceTM Conference

Symposium Title:     Integrating BIM: Moving the Industry Forward

Day(s)/Date(s):          January 7-11, 2013

Monday and Tuesday: Board, Council and Committee Meetings

Tuesday and Wednesday: Conference Educational Sessions

Thursday: Information Exchanges

Friday: BIM Academic Education Symposium

Building information modeling (BIM) is beginning to fundamentally change the building industry in a very positive way. Its impact is already being felt in countries around the globe. In an industry known for construction delays and cost overruns, high quality BIM projects are being built on-time (or even early) and significantly under budget.

Now is the time to expand your knowledge of all things BIM and find ways to implement it in your work. The buildingSMART allianceTM Conference will help you understand how BIM can better integrate the design, construction, fabrication and operation processes, and provide you with the latest metrics available to assess industry progress.

With the theme, Integrating BIM: Moving the Industry Forward, the buildingSMART alliance Conference looks at the big picture of implementing BIM into daily practice. The week-long event includes committee meetings, such as the buildingSMART alliance Board of Direction, National BIM Standard-United States Planning and Project Committee meetings; two days of educational sessions; a full day of innovative technology demonstrations with the Information Exchange Working Group; and a BIM Academic Education Symposium focused on teaching the next generation.

The National BIM Standard-United States (NBIMS-US) Version 3 Planning and Project Committees will begin planning the new standard during these face-to-face meetings. The Planning Committee Meeting is members-only. However, the Project Committee is open to anyone interested in becoming involved. It is a good place to start if you are considering joining the NBIMS effort. The buildingSMART alliance Board of Direction Meeting is also open to the public.

The buildingSMART alliance Conference Educational Sessions are broken into two days. The first day will focus outwardly on three aspects of BIM implementation: design-construction integration, construction-fabrication integration and construction-operations integration, as well as developing the metrics that can be used to assess what progress the industry is making, on an annual basis, toward process improvement. The second day will be more of an inward look at the standards under development by the Alliance, as well as various standards efforts and strategies on the international front.

During its all-day meeting of innovative technology demonstrations, the Information Exchange (IE) Working Group will reveal the newest, most cutting-edge building information modeling (BIM) information exchange standards for inclusion in the National BIM Standard-United States™. The meeting, which is free and open to the public, is where the latest progress will be presented and the course of information exchange development will be set for the year.

The week will close with the BIM Academic Education Symposium. This workshop, jointly sponsored by the buildingSMART alliance and the BIM Forum,consists of a day-long series of presentations by leading BIM educators on topics related to implementing academic curricula at their educational institutions. The topics include the use of BIM in: student projects, interdisciplinary collaboration in studios, scheduling and estimating classes, IPD projects and facilities management. Researchers, academicians and practitioners in the AECOO industry are all strongly encouraged to attend and help shape the future of BIM integration in academic curricula.

BIM for Owners = BIM for FM, Building Information Modeling for Facility Managment

ImageImageImageImage

Ok, so we get that 3D visualization is a component of BIM.  Design concepts can be beautifully illustrated, and one can relatively easily make a change to the model and the output documents update. Clash detection and the ability to eliminate clashes prior to the construction work starting is also a big “plus” for BIM.  Now it is time to focus on the information in BIM.

It’s time to focus on the true value of BIM for Owners (as well as Contractors, Oversight Groups, the general Community, etc.), the efficient life-cycle management of the built environment.

There are major challenges to attaining BIM, the most significant being change management.  For example, the traditional culture of the AECOO sector (Architecture, Engineering, Construction, Operations, Owner) has been based upon adversarial, non-collaborative ways of conducting day to day business.  As a result, sharing information, consistency, and standardized efficient practices have been difficult at best.

Cloud computing, as well as major market drivers may force change.   That said, when information   becomes more widespread, what standards will it be authored to?  How are things and/or objects defined?  How and when will information be updated?  What specifics and/or parameters are required to define or redefined and object.  For example take a door –  physical configuration (accessibility, dimensions, weight, materials, manufacturer, year built/age), functional aspects(acoustic rating, fire rating, thermal transmittance, security, self-closing, condition, cost, replacement cost, life-cycle), maintenance requirements, warranties?

Also the above, and more, must be considered for the “I” in BIM, in order to fulfill the definition of BIM.

A shared digital representation of physical and functional
characteristics of any built object including buildings,
bridges, roads, process plants etc. forming a reliable basis
for decisions. – ISO

Building Information Modelling (BIM) is the process of generating and managing data about the building, during its life cycle. Typically BIM uses three-dimensional, real-time, dynamic building modelling software to increase productivity in the design and construction stages. – NBS

Building Information Modelling (BIM) is a new approach to being able to describe and display the information required for the design, construction and operation of constructed facilities. It is able to bring together the different threads of information used in construction into a single operating environment thus reducing, and often eliminating, the need for the many different types of paper document currently in use. To use BIM effectively however, and for the benefits of its use to be released, the quality of communication between the different participants in the construction process needs to be improved.
If the information needed is available when it is needed, and the quality of that information is appropriate, then the construction process can be improved. For this to happen, there must be a common understanding of building processes and of the information that is needed for and results from their execution. The Industry Foundation Classes (IFC) provides a comprehensive reference to the totality of information within the lifecycle of a constructed facility. It has been created as an integrated whole in response to the identification of business needs expressed by the international building construction community. It does not contain a comprehensive reference to individual processes within building construction.
The case for a comprehensive reference to processes in building construction is clear and compelling. By integrating information with the process, the value of such a reference is greatly enhanced and it becomes a key tool in really delivering the benefits of BIM.  – buildingSMART, NIBS

The future of BIM modeling is to expand the information model to include more of the life cycle phases (ie: real property commerce, maintenance and operations, environmental simulation, etc.), to standardize life cycle process definitions and associated exchanges of information, and to standardize information content so that meanings and granularity are clear and consistent. This expanded scope definition will make BIM useful to a wider community including, for example, real property managers, appraisers, brokers, mortgage bankers, facility assessors, facility managers, maintenance and operations engineers, safety and security personnel as incident responders, landscape architects, infrastructure engineers and operators, and others outside the business verticals associated with new building design and construction. – BIM Initiative – NIBS

COBIE – BIM – Life-cycle Facility Managment

After a 3 month period of international review, the COBie Guide has just been published on the buildingSMART alliance website.  The COBie Guide can be considered the “commentary” to the COBie information standard “code”.  The Guide provides enforceable quality standards for the delivery of COBie data. To obtain a copy click COBie_Guide_-.

This version of the COBie Guide will be submitted for United States National BIM Standard balloting in the next round.  The Guide is organized to allow the specification of regional and client customization. As a result, it is hoped, that this document can be applied to accelerate the already rapid use of COBie world-wide. – Bill East, US Army October 9. 2012 – via FMOC

The quality standards identified in this Guide will be built into the bimserver.org COBie checking routines to provide anyone using COBie a free quality control tool.

The COBie Guide: a commentary to the NBIMS-US COBie standard
by Dr. Bill East, PhD, PE, F.ASCE1, Mariangelica Carrasquillo-Mangual 2
EXECUTIVE SUMMARY
The Construction-Operations Building information exchange (COBie) format is the international standard for the exchange of information about managed facility assets. COBie does not add new requirements to contracts; it simply changes the format of existing deliverables from paper documents and proprietary formats, to an open, international standard format.
While COBie provides the format for the exchange of required asset information, it does not provide details on what information is to be provided when, and by whom. This Guide provides best-practice guidelines for these requirements. This Guide can be considered the “commentary” that accompanies the COBie format specification. To use this guide, customizations reflecting regional practices, specialized project types, and client’s requirements should be documented in Appendix A. The correct application of the COBie Guide may then be reference directly in appropriate specifications.
As of 2012 over twenty commercial software products support COBie. These products cover the entire facility life-cycle from planning, design, construction, commissioning to operations, maintenance, and space management. Software implementers will find the information in Appendix B helpful for low-level mapping of required properties.

Abstract
In previous work, building information models (BIMs) were developed for three buildings: Duplex Apartment, Office, and Clinic. However, the mod-els were developed inconsistently and contain differing levels of detail and quality of content across disciplines. One reason for these differences was the lack of an ontology that describes the specific requirements for life-cycle modeling for the heating, ventilating, and air conditioning (HVAC) domain. The objective of the work described here was to develop an ontol-ogy for the design phase of typical HVAC systems found in low-rise Army facilities.
This report documents the process modeling and data-exchange require-ments of HVAC engineering design practice, following Information Deliv-ery Manual (IDM) and Model View Definition (MVD) procedures defined by the International Organization for Standardization (ISO) and the buildingSMART Alliance.

1 Introduction
1.1 Background
The US Army Engineer Research and Development Center, Construction Engineering Research Laboratory (ERDC-CERL) has developed a core life-cycle building information model based on three example Army buildings: an Officer Duplex Apartment, a Headquarters Office, and a Clinic. These models were developed inconsistently over time by different modelers, and they reflect different levels of detail and quality of content across disci-plines. One cause for these differences is that an ontology describing the requirements for life-cycle modeling has not been identified for the heat-ing, ventilating, and air-conditioning (HVAC) domain. Current efforts at HVAC modeling typically focus only on those hard physical collisions be-tween ductwork and structural or architectural building elements. One of the difficulties of modeling the HVAC system is the complexity of the sys-tem itself.
Life-cycle information exchanges have previously been identified in the structural steel domain—an analysis model, a design model, and a detailed model. The analysis model reflects the needs of structural engineers to evaluate the requirements of the building and size the system to meet the facility’s requirements. The design model shows sufficient detail to allow construction contractors to bid. The detailed model provides fabrication and erection details required to physically construct and connect the sys-tem. A life-cycle model for HVAC systems includes a similar phased set of information needed to effectively support activities over the facility life cy-cle.
Traditional Army HVAC systems include four major subsystems. The first is the circulation of a thermal fluid, typically water that is heated or cooled, depending on the season. The second is the set of equipment needed to transfer energy from the thermal fluid to a thermal transfer fluid, typically air. The third subsystem is the transport mechanism for the thermal trans-fer fluid. This thermal transfer fluid is circulated by pressure differentials in the case of ductwork systems, or through convection currents in the case of radiators and fan coil units. The fourth subsystem is the set of sen-sors that provide a feedback loop to ensure proper delivery of thermal flu-
ERDC/CERL CR-12-2 2
id, heat-transfer rate of equipment, and adequate distribution of thermal transfer fluid.
The work accomplished in this effort complements efforts being conducted by organizations developing and promoting energy modeling tools. It is intended to establish a common minimum standard framework, used on typical Army facilities, to describe the components and topology of HVAC systems from an HVAC engineering design perspective. This work will help to establish the foundation for the delivery of HVAC models during the design stage, thereby easing the requirements on energy modeling tools that currently force the manual entry of higher-order HVAC infor-mation that is not available today.
1.2 Objectives
The objective of this work was to develop and document an ontology ad-dressing the specific requirements for the design-phase of HVAC systems typically found on low-rise Army facilities such as housing, offices, and clinics.
1.3 Approach
The HVAC design process was mapped in order to identify and document all specific data-exchange requirements relevant to the HVAC engineering design practice. This work was executed in conformance with the Infor-mation Delivery Manual (IDM) and Model View Definition (MVD) proce-dures defined by the International Organization for Standardization (ISO) and the buildingSMART International Alliance for Interoperability (e.g., Wix 2007 and Hietanen 2008).
ERDC/CERL CR-12-2 3
2 HVAC System Design Process Models
2.1 Overview
The selection, design, and modeling of Heating, Ventilating, and Air-Conditioning (HVAC) domain equipment and systems involve iterative, evolutionary, collaborative processes. The HVAC Designer should be an active member of the design team, ideally beginning in early project plan-ning, interacting with other team members and the Project Owner pri-marily through the Architect who is coordinating the overall design pro-cess.
The process model details in this document focus on the HVAC Designer Activity Tasks and Data Exchanges as part of the overall design process. Activity Tasks and Data Exchanges performed by other design team mem-bers are represented here only through interactions and communications with the Architect, without explicit representation of Tasks and Data Ex-changes performed by other team members.
2.1.1 HVAC system design phases
The overall design process can be divided into a variety of incremental phases that may vary depending on the project contracting type. The Pro-cess Models detailed in this document represent commonly identified phases applicable to most contracting types in the United States. The phases included here are Programming, Concept Design, Schematic De-sign, Design Development, and Construction Documents production. The-se combined phases bring a project from early planning to the point of generating design construction documents for bidding the project.
2.1.1.1 Programming and concept HVAC system design
The Programming phase of design focuses on identifying and codifying the requirements for fulfilling the needs and wants of the Owner of a project. These requirements can be referred to as the Owner’s Project Require-ments (OPR) as defined in the ASHRAE Guideline 0 (ASHRAE, 2005).
From the Architect’s perspective, Programming will focus on functional space requirements and budget constraints as well as higher-level objec-tives such as the Owner’s desired level of energy-efficiency and aesthetic
ERDC/CERL CR-12-2 4
considerations. From the HVAC Designer’s perspective, Programming will focus on proposing HVAC-related space requirements and understanding potential impacts of identified OPRs on HVAC-related issues.
The Concept Design phase will begin to develop conceptual design alterna-tives that meet the identified OPRs. The level of detail developed in Con-cept Design will vary depending on the project contractual type and agreements. These variations may range from simple overall massing and orientation concepts to relatively complete layout of functional spaces.
The HVAC Designer will work with the level of Concept Design detail pro-vided by the Architect to elaborate HVAC systems as much as possible without performing work that requires additional detailed assumptions that will likely change dramatically as design proceeds. The HVAC Design-er will develop early Basis of Design documentation including at least sug-gested HVAC system types, and propose HVAC-related spatial require-ments. The HVAC Designer may also perform preliminary HVAC cost and whole-building energy performance estimations based on available design data, as appropriate for evaluation of Concept Design alternatives.
Ideally, sufficient levels of detail will be modeled using a Building Infor-mation Modeling (BIM) tool for sharing amongst Design Team members. An Owner accepted Concept Design BIM will then be passed to the Sche-matic Design phase for further elaboration.
2.1.1.2 Schematic HVAC system design
The Schematic Design phase will build on the previously developed Con-cept Design to add significantly more detail to the accepted conceptual de-sign. From the perspective of the HVAC Designer this will include selec-tion and preliminary sizing of main HVAC equipment for the proposed system types; coordination of Mechanical Equipment Room (MER) spaces within a combined architectural, structural, and MEP (mechanical, electri-cal, and plumbing) design model; zoning of functional spaces into HVAC zones; and estimation of whole-building energy performance and HVAC system construction costs as appropriate given known building infor-mation. Sizing, performance, and cost estimates may still be based on simplified functional-area-based methods. Preliminary piping schematics and air-flow diagrams may also be developed at this point.
ERDC/CERL CR-12-2 5
An Owner accepted Schematic Design BIM will be passed to the Coordi-nated Design phase for further elaboration.
2.1.1.3 Coordinated HVAC system design
Coordinated Design comprises two phases commonly referred to as Design Development and Construction Documents. Design Development elabo-rates the accepted Schematic Design to the level of detail required to fully evaluate its acceptability. The production of Construction Documents then generates documentation of the accepted design to support the process of Construction Bidding.
From the perspective of the HVAC Designer, in coordination with the De-sign Team through the Architect, Design Development finalizes the selec-tion of HVAC equipment and MER layout, adds more complete HVAC dis-tribution system layout, enhances and updates building information required for accurate HVAC-related calculations, finalizes those calcula-tions, and documents as much HVAC information as possible in the coor-dinated Design Development BIM.
An Owner accepted Design Development BIM is then used as the basis for generating Construction Documents.
2.2 Specification of processes
This section of the document contains three Process Map diagrams cover-ing the HVAC design phases of (1) Programming and Concept Design, (2) Schematic Design, and (3) Design Development and Construction Docu-ments production. Immediately following each of the three diagrams be-low are textural descriptions of the Activities and Events shown in each diagram. Textural descriptions of the combined set of data exchange ob-jects shown in all of the diagrams are given in the Specification of Data Objects section.

3 Exchange Requirements and Functional Parts
This section provides a more detailed overview of each of the exchange re-quirements identified above and their related functional parts. Further de-tails, including tabular listings of objects and properties within each ex-change requirement are given in separate documents adhering to the Information Delivery Manual (IDM) formats. Compressed archives of each exchange requirement and its related functional parts are listed below.
3.1 er_exchange_building_model[basic].doc
A basic building model is defined as ‘the set of information that provides both a graphical representation of the design of a building and key pieces of information about the building that can be further used to analyze building performance’ (from http://www3.autodesk.com/apac_sapac_main/files/4525079_BIM_A_Key_to_Performance-Based_Design.pdf)
The purpose of exchanging a basic building model is to provide infor-mation about a building that enables downstream analyses (structural, thermal, lighting, acoustic etc.) to be undertaken, and that supports facility management activities in the occupied building. The basic building model provides information about the building, the layout of spaces within it and the main building elements from which it is to be constructed
Particular information that is required with the basic building model in-cludes:
• the name of the project (for identification purposes) and the units gen-erally used throughout the project; additionally, the current phase of the project may be given but this is not mandatory
• configuration of a site on which a building is located including the geo-graphical location (latitude, longitude and elevation above sea level for the site datum) and shape layout
• further information about a site may be provided including land title number and local address
ERDC/CERL CR-12-2 36
• location of a building in connection with a site or external space on which it is located
• overall shape of a building with its plan shape at various heights and elevation shape at various orientations so that building areas, height, volume and building mass can be established
• configuration of levels or storeys within a building with their plan shape and height so that areas and volumes can be established
• configuration of spaces within a building or building storey, including both partial and complete/room spaces and the association between partial and complete spaces, with their plan shape and height so that areas and volumes can be established; this allows for the definition of atrium spaces that span more than one storey of a building
• spaces should have a name and a type that specifies their function (for later use in analysis)
• dimensional information concerning spaces should enable calculation of areas and volume and include length, width and height information and the plan shape of the room.
• the elevation of spaces above the building reference should be given.
• one or more 3 dimensional shape representations should be defined for the space including at least a ‘bounding box’ representation (the box that contains the space shape) and probably a more detailed 3 dimen-sional representation of the boundaries of the space.
• arrangement of major building elements within a building and within the storeys of a building with their shape so their typical length, width, height dimensions can be established; major building elements being defined as walls, floors, roofs, ceilings
• shape representations of building elements should be defined including their 2D profile, bounding box and 3 dimensional representation of their boundaries.
• type or style definitions should be given where a given type or style of building element will be used many times; each occurrence of a build-ing element will be designated as being of a particular type
• provision of openings within buildings elements within which further building elements can be constructed to fill the openings (referred to as ‘filling’ elements)
• provision of filling elements with their shape so that their typical length and height dimensions can be established; filling elements being de-fined as doors, windows, skylights/rooflights
ERDC/CERL CR-12-2 37
• shape representations of filling elements should be defined including their 2D profile, bounding box and 3 dimensional representation of their boundaries.
• type or style definitions should be given where a given type or style of filling element will be used many times; each occurrence of a filling el-ement will be designated as being of a particular type
• relationships between openings and major elements and between openings and filling elements so that the identity of particular filling elements within particular major elements can be determined
• Optional information that may be required with the basic building model includes:
• material from which a building element or filling element is construct-ed
• classification of spaces, building elements and filling elements accord-ing to particular classification systems and tables
• connection relationships between major building elements
For a complete specification of this exchange requirement and its related functional parts see ERDC_er_exchange_building_model[basic].zip
3.2 er_exchange_HVAC_model[space].doc
The scope of this exchange requirement is the exchange of information to enable provision of technical spaces that have as their primary purpose the housing of HVAC or other technical equipment. The purpose of the ex-change requirement is to enable coordination of HVAC systems space re-quirements with other technical systems requirements (notably electrical and piping systems) and with building design with regard to the provision of space for the technical systems.
This exchange requirement allows for the provision of information at vari-ous stages during the design process including outline conceptual or sketch design, full conceptual design and coordinated design. The infor-mation provided at each stage is essentially the same. However, the level of certainty regarding equipment and components used will increase at each stage allowing greater certainty in space provision.
It is assumed that the information provisions outlined in the exchange re-quirement er_exchange_building_model[basic] have been satisfied for the project stage concerned. This provides an initial assessment of spaces from the perspective of building design and project details.

• Proposed technical space specification with area, configuration and height. At earlier stages of design, area and height only may be given; later stages of design may also propose a space configuration.
For a complete specification of this exchange requirement and its related functional parts see ERDC_er_exchange_HVAC_model[space].zip
3.3 er_exchange_HVAC_model[equipment].doc
The scope of this exchange requirement is the exchange of information to enable coordination of HVAC Equipment with other technical design roles, building design and structural design. It includes the need for shape, size and location of components and also for weight, as well as other equip-ment properties to be included.
This exchange requirement allows for the provision of information at vari-ous stages during the design process including outline conceptual or sketch design, full conceptual design and coordinated design. The infor-mation provided at each stage is essentially the same. However, the level of certainty and specificity regarding equipment and components will in-crease at each stage allowing greater certainty in space provision. Addi-tionally, equipment and components may still be specified at a generic lev-el at the end of design, with specification of manufactured equipment and components coming during procurement and construction.
It is assumed that the information provisions outlined in the exchange re-quirement er_exchange_HVAC_model [space] have been satisfied. This provides an initial assessment of spaces from the perspective of building design and HVAC design as well as project details.
Information provided through this exchange requirement includes:
• HVAC equipment component type and size
• Shape representation of component type
• Weight of component type
• Location and orientation of occurrences of component type
• Properties of the equipment types and occurrences required for HVAC design process

3.4 er_exchange_HVAC_model[systems].doc
This exchange requirement describes the information to be provided about duct and pipe HVAC systems. It allows for the provision of information at various stages during the design process including:
• Representation of components and their relation to spatial structures (sites, buildings and spaces) without connection to systems
• Line based representations at early design stages that enable routing, terminal location and main plant location information to be ex-changed;
• Full 3D shape representations at detailed design stages that enable co-ordination between different building services systems, between ser-vices and structure and between services and the building construction elements.
Information items that may be required about HVAC duct systems in-clude:
• System name
• Terminal type, size, location, orientation, airflow rate, discharge veloci-ty, pressure drop; supply air temperature may also be included for supply air systems.
• Duct section size, shape, location, flow rate, air velocity, pressure drop
• Duct fitting type, size, location, pressure drop
• Equipment type, size, location, pressure drop
• Shape of elements
• Connections between elements in the ductwork system
• Material from which elements are constructed
• Classification of elements
Constraints that have been applied during the design of the duct systems to limit or control duct sizing or equipment selection may also be included as part of the exchange requirement. These should be identified as a re-quirement by the user. Particular constraints considered include:
• Limiting pressure drop in a ductwork section
• Limiting velocity in a ductwork section
ERDC/CERL CR-12-2 40
• Limiting dimensions for a ductwork section (height, width, diameter)
• Ductwork construction standard
• Duct sizing method
Information items that may be required about piping systems include:

• Pipe fitting type, size, location, pressure drop
• Equipment type, size, location, pressure drop
• Shape of elements
• Connections between elements in the piping system
• Material from which elements are constructed
• Classification of elements
Constraints that have been applied during the design of the pipe systems to limit or control pipe sizing or equipment selection may also be included as part of the exchange requirement. These should be identified as a re-quirement by the user. Particular constraints considered include:
• Limiting pressure drop in a pipe section
• Limiting velocity in a pipe section
Note that as of IFC2x4 a specialization of System (ifcDistributionSystem) has been added to capture the concepts of a distribution system in a new element. The distribution system has predefined types for various heating, cooling, ventilation, plumbing, security and electrical systems.
Information provided through this exchange requirement also includes:
• Grouping of spaces into zones served by an identified system

4 Model View Definition
This section formalizes the combined information delivery requirement arising from the exchanges required based on the process maps. This sec-tion summarizes the necessary content which is available as a complete Express sub-schema and associated documentation produced to the ISO/buildingSMART international standard.
4.1 Inputs to a HVAC MVD
The following considerations have been derived from the Process map and Exchange requirements above, from the practical considerations discov-ered in modeling the three building types and from consideration of the two primary MVD definitions that support the design and documentation of HVAC systems.
4.2 buildingSMART Coordination Model View Definition 2.0
Design and documentation of HVAC systems must be conducted in the context of a detailed description of the architectural fabric and spatial re-quirements of the facility.
In particular the HVAC subset of the Coordination view allows for the use of the critical connectivity port objects and relationships:
• IfcPort and IfcDistributionPort
• IfcRelConnectsPortToElement and IfcRelConnectsPorts
4.3 buildingSMART FM-10 Handover Model View Definition
It is also central to an integrated working method that the design and doc-umentation of HVAC systems deliver information appropriate to and use-ful for the handover process, thereby supporting the owner/operators spe-cific use cases:
• Registration of assets including spaces and equipment
• Use of the facilty and effective utilization.
• Operations and Maintenance of the systems
• Refurbishment and replacement of equipment
• Tracking of cost and environmental impacts
ERDC/CERL CR-12-2 43
• Security and safety during use.
In summary, the COBie Handover view includes business rules that re-quire:
• Every occurrence, space, type, zone and system being uniquely named. This also applies to the project, site, building, building floor.
• Every occurrence having an associated uniquely named type.
• Every occurrence being related to a space.
4.4 Other considerations
Whilst these two MVDs actually support the required data, practical expe-rience gained in this project in the areas of design checking and validations suggests that further additional business rules are needed to enforce the use of available objects. These rules include both practical (and universal) rules and rules
4.5 Connectivity
Additional rules are defined to ensure that full connected systems are cre-ated.
• All ‘Ifc Flow Segments’ relating to HVAC distribution (‘Ifc Duct Seg-ment Type’) to have exactly 2 ‘Ifc Distribution Port’s.
• All ‘Ifc Distribution Port’s to be paired by a connecting relationship with no sink-to-sink nor source-to-source connections.
Other objects including IfcFlowTerminals may or may not have ports, de-pending on whether they are part of the HVAC systems.
4.6 Analysis
Although not central to the scope of this project, the HVAC MVD should demand inclusion of the associated property sets for spaces and HVAC systems relating to
• Demand-side design (cooling load and heating load for each space based on outside air, ground, solar, occupancy)
• Supply-side design (temperature and pressure drops along ductwork)
ERDC/CERL CR-12-2 44
• Equipment selection (boilers, chillers, air handlers, cooling towers, etc.)
• Load simulation
• Performance data, balancing.
These requirements may be developed further to reflect the US ASHRAE guidance.
ASHRAE, 2005. ASHRAE Guideline 0 -2005: The Commissioning Pro-cess, Informative Annex J – Owner’s Project Requirements.
ASHRAE, 2005. ASHRAE Guideline 0 -2005: The Commissioning Pro-cess, Informative Annex K – Basis of Design.
4.7 Classification
Analysis and reporting demand that the spaces, systems and objects with the model should be correctly classified.
• A library of common industry construction and material type perfor-mance data used in HVAC-related calculations keyed to accepted cate-gorization schemes from sources such as ASHRAE 90.1, CA Title 24, or Omniclass Tables 21 and 23
• A library of industry Space Type requirements used in HVAC-related calculations keyed to an accepted Space Type categorization scheme from sources such as ASHRAE 90.1, CA Title 24, GSA, or Omniclass Tables 11 and 13.
It is not clear yet how far the encoded business rules can express this re-quirement, but the rules include:
• The classification shall be to Omniclass 2010 Tables.
• Buildings shall be classified to Omniclass 2010 Table 11
• The Spaces (and Zones) shall be classified to Omniclass 2010 Table 13
• The Systems shall be classified to Omniclass 2010 Table 21
• The Types and Materials shall be classified to Omniclass 2010 Table 23

The BIM Evolution Continues with OPEN BIM Draft V8 20120131

What is BIM?
BIM is an acronym which represents three separatebut linked functions: Building Information Modelling:
Is a BUSINESS PROCESS for generating and leveraging building data to design, construct and operate the building during its lifecycle.
BIM allows all stakeholders to have access to the same information at the same time through interoperability between technology platforms.
Building Information Model:
Is the DIGITAL REPRESENTATION of physical and functional characteristics of a facility. As such it serves as a shared knowledge resource for information about a facility, forming a reliable basis for decisions during its life-­‐cyclefrom inceptiononwards.
Building Information Management:
Is the ORGANIZATION & CONTROL of the business process byutilizing the information in the digital prototype to effect the sharing of information over the entire lifecycle of an asset. The benefits include centralizedand visual communication, early exploration of options, sustainability,  efficient design, integration of disciplines, site control, as built documentation, etc. – effectively developing an asset lifecycle process and model from conception to final retirement.

What is OPEN BIM?
OPEN BIM is a universal approach to the collaborative design, realization and operation of buildings based on open standards and workflows.
OPEN BIM is an initiative of buildingSMART International (bSI) and several leading software vendors using the open buildingSMART Data
Model. Why is it important? OPEN BIM supports a transparent, open workflow, allowing project members to participate regardless of the
software tools they use. OPEN BIM creates a common language for
widely referenced processes, allowing industry and governmentto procure projects with transparent commercial engagement,comparable service evaluation and assured data quality. OPEN BIM provides enduring project data for use throughout the asset life-­‐cycle, avoiding multiple input of the same data and consequential errors. Small and large (platform) software vendors can participate and compete on system 9ndependent, “best of breed” solutions. OPEN BIM energizes the on-­‐line product supply  side with more exact user demand searches and delivers the product data directly into the BIM.
