Framework for building information modelling (BIM) guidance
ISO/TS 12911:2012 establishes a framework for providing specifications for the commissioning of building information modelling (BIM). It is applicable to any range of modelling of buildings and building-related facilities, from a portfolio of assets at a single site or multiple sites, to assets at a single small building and at any constituent system, subsystem, component or element. It is applicable to any asset type, including most infrastructure and public works, equipment and material. BIM processes are applicable across the entire life cycle of a portfolio, facility or component, which can span inception to end-of-use. The main user of the framework is the information manager, who utilizes the framework to assist in structuring an international-, national-project- or facility-level BIM guidance document. The framework can also be used for BIM guidance provided by application providers.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical
experts in an ISO working group and is accepted for publication if it is approved by more than 50 %
of the members of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a
technical committee and is accepted for publication if it is approved by 2/3 of the members of the
committee casting a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for
a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or
ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be
transformed into an International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 12911 was prepared by Technical Committee ISO/TC 59, Buildings and civil engineering works,

TECHNICAL SPECIFICATION ISO/TS 12911:2012(E)
Framework for building information modelling (BIM)
guidance
1 Scope
This Technical Specification establishes a framework for providing specifications for the commissioning
of building information modelling (BIM).
This Technical Specification is applicable to any range of modelling of buildings and building-related
facilities, from a portfolio of assets at a single site or multiple sites, to assets at a single small building
and at any constituent system, subsystem, component or element. It is applicable to any asset type,
including most infrastructure and public works, equipment and material. BIM processes are applicable
across the entire life cycle of a portfolio, facility or component, which can span inception to end-of-use.
The main user of the framework is the information manager, who utilizes the framework to assist in
structuring an international-, national-project- or facility-level BIM guidance document. The framework
can also be used for BIM guidance provided by application providers.

4 Intentions
4.1 Intention of the framework
The construction and facilities industry is adopting the use of object-orientated methods in capturing
the information about its products. This is being driven internally by demands for efficiency and
externally by demands for a higher quality and value in the product. In order to maximize the return on
this investment, the industry needs better structured and more re-usable performance specifications.
This Technical Specification specifies a framework for providing a specification for the commissioning of
BIM. The framework allows international-, national- and project-specific BIM guidance documents to be
collated and partners in new projects to assimilate the practices and expectations of other partners. It
is intended that supplements be merged into or appended to this Technical Specification. The objectives
of the framework are the following.
a) Create a common framework giving guidance for the application of BIM:
1) aid the development of clear and repeatable processes;
2) allow international, national and project/enterprise guidance document to be prepared
according to a common framework;
3) allow application guidance documents to be prepared according to the same common framework.
b) Make BIM guidance documents manageable:
1) encourage completeness of guidance documents by providing a check-list of outcomes,
management and inputs;
2) encourage the provision of reasoned explanations for demanded performance;
3) achieve extensibility of guidance documents;
4) support the merging and comparing of “BIM guidance” documents.
c) Make BIM guidance able to be tested:
1) encourage the testing of guidance documents against this framework;
2) encourage the testing of BIM usage against guidance documents;
3) encourage the use of formal contractual clauses which refer to guidance documents.

4.2 Intention of BIM guidance documents
BIM guidance documents are used for a variety of purposes, including to
a) establish the desired outcomes and define appropriate quality,
b) identify appropriate management effort and tools,
c) identify necessary effort and resourcing, and
d) achieve and maintain a common understanding within the national and project contexts.
4.3 Overview of framework sections
BIM guidance documents may additionally address the presentational conventions for application in the
generation of drawings and documents. This content may be carried forward from national and project
drawing and document production standards.
Principals, design managers and end users should be able to easily navigate and understand any BIM
guidance document that results from implementation of this Framework. The enterprise is supported
when the objectives for using BIM (BIM guidance Framework section 1: Outcomes) is reviewed and
approved at the principal level. Design management (BIM guidance Framework section 2: Controls)
is supported by reviewing and implementing the management policies needed. Since these policies
are keyed into the overall objectives, the dialogue between the design manager and the principals is
supported. Design teams can review and implement the input requirements (BIM guidance Framework
section 3: Controls) as this defines what they shall do. Again, since these requirements are keyed into
the management policies, the dialogue between the design teams and design manager is supported.
The style and content is intended to ensure that the requirements within the guidance document are
directly measurable either by human inspection or by automated checking.
A BIM guidance document may be provided at an overall project or facility level, but may also be provided
more specifically for individual BIM sub-processes within those overall objectives. These individual
processes may be arranged in series and in parallel. The IDM methodology (as given in ISO 29481-1) shall
be used to document, review and specify new BIM processes. The outcomes of review of new processes
should then be documented in the BIM guidance document, thus adhering to this framework.

5 Formal aspects of BIM information exchange
5.1 General recommendations
The following recommendations are intended as a checklist for the formal aspects of information
exchange arising from the use of BIM a guidance document .
5.2 Delivery agreement
An agreement may be written for each process where data are exchanged between actors, for a project
or a facility. The objective of the agreement is to specify the purpose, how the delivery shall be conducted
and controlled and what data are to be delivered. The agreement should be harmonized with national
legislation, as well as with other contractual documents. It may be included as part of a contract for
a service or as an attachment to the contract. It may specify the consequences of non-fulfillment of
the requirements. The agreement on information delivery/exchange should only cover this where the
compensation for faults in delivered information is not covered by the main contract for the assignment.
5.3 Specification of content
The intended result (deliverables) may be specified by use of this framework. The agreement may cover
how the information shall be delivered and/or stored, including:
a) file or database format;
b) data schema;
© ISO 2012 – All rights reserved 5
---------------------- Page: 9 ----------------------
ISO/TS 12911:2012(E)
c) media or data repositories.
5.4 Acceptance
The process of checking/reviewing the information may be stated, whether by the sender and/or the
receiver; the methods and tools to be used may be stated also.
5.5 Owner’s rights and rights for use of information
If ownership of the information is not explicitly transferred, the agreement may allow or disallow
other usage and/or modification of the information. The terms of the agreement should comply with
intellectual property rights as expressed in laws and industry agreements.
5.6 Responsibility
Normally, the supplier of the information is responsible for the information fulfilling the requirements.
A model may, however, contain information that is not appropriate for the purpose of the delivery. The
agreement should make clear whether responsibility should include all information delivered, only a
specified subset or everything except a specified subset. A model may include information supplied by
several actors. It should be made clear whether one actor takes responsibility for all content or if each
actor is responsible for separate contributed parts. A third option is for responsibility to be shared by
the group which participated in creating the model, without pointing out specific parts.
5.7 Traceability
In order to follow up on an agreement, the entities delivered on different occasions should be recorded;
communication regarding the deliveries should be recorded as well .
If responsibility for parts of an information model is divided between actors, there should also be a method
for documenting the responsible actor for each part of the model and the actions/versions for each part.
5.8 Compliance
This framework is intended to support rigorous testing of compliance with the BIM guidance document.
This should be achieved by inspection or by the application of automatic compliance checking configured
with the content of a BIM guidance document. In either case, it is expected that:
a) every BIM object, attribute and relationship shall satisfy all of the objectives defined in Framework
section 1: Outcomes;
b) the results make reference to objectives from other clauses of the document;
c) a BIM object, attribute and relationship shall satisfy an objective by showing that it is not applicable,
is not selected, is excepted or is as required.
5.9 Implications of non-compliance
Compliance with the framework is intended to be tested according to Section 6. Non-compliance can
impact usability of the BIM guidance document and create difficulties in the coordination of separate
BIM guidance documents and so lead to contractual ambiguities.
Compliance with the BIM guidance document is intended to be tested against the levels of results, the
management and the input stages documented in A.1, A.2 and A.3. Non-compliance can impact the
quality and efficiency of project/facility delivery.

ISO/TS 12911:2012(E)
6 The framework for the BIM guidance document
6.1 Overview of the framework
6.1.1 General
The framework shall be mandated/adopted/applied/implemented for use by authors at international,
national and project/facility levels. National bodies and organizations responsible for projects or
facilities may mandate the framework and BIM guidance document produced according to it.
It shall be implemented for use in BIM guidance documents on specific facilities and projects.
The authoring conventions for International Standards should be maintained at every level of the
guidance document so that titles have no effect, but the body text shall be normative, including the
invocation of other clauses. It shall be possible to test every framework section.
The guidance document shall be divided into three sections or areas; for BIM Sections 1 to 3, see Figure 2.
For additional details, see Annex A.
6.1.2 Framework section 1: Outcomes
The outcomes section shall provide guidance for the specification of the desired results.
The content may be derived from the IDM process and exchange requirement deliverables or other
documents defining the structure and content of the desired results.
6.1.3 Framework section 2: Controls
The controls section shall provide guidance for the specification of managerial processes and quality
assessment associated with the process of BIM.
The content may be derived from the IDM validation rules and business rules deliverables or other
documents defining the constraints on the desired results.
6.1.4 Framework section 3: Input
The input section shall provide guidance for the specification of the inputs required to achieve the aims
selected in Framework section 1: Outcomes and the managerial processes required by Framework
section 2: Controls.
The content may be derived from the IDM functional parts and concepts, deliverables or other documents
defining units of information necessary for the desired results.
6.2 Integrity
The fundamental structure of the framework shall be maintained.
The fundamental structure of the framework makes certain that there is consistency and compatibility
between guidance documents. This ensures that each BIM process can be developed, approved and
implemented at the appropriate level of management and responsibility, and ensures that similar clauses
can be easily located and reviewed.
The following features are required.
a) The guidance document shall be organized into three framework sections, relating to the desired
outcomes, controls and inputs.
b) Decimal numbering shall be used and each clause shall have a title. There shall be further subdivisions
as indicated in Annex A.
© ISO 2012 – All rights reserved 7
---------------------- Page: 11 ----------------------
ISO/TS 12911:2012(E)
c) The ordering and numbering of the clauses shall be maintained.
d) Three levels of guidance shall be distinguished:
1) international clauses shall be entitled “Common . ” and their numbers given the suffix “A”;
2) nationally and regionally mandated policies shall be entitled “National . ” and their numbers
given the suffix “B”. This may include guidance provided by professions and associations;
3) project- and facility-specific implementations shall be entitled “Specific .” and their numbers
given the suffix “C”. This may include guidance provided with specific applications and
implementation conventions, including owners or corporate policies.
e) every reference to a clause shall correspond to a clause appearing later.
6.3 Extensions
The integrity of the framework, as defined in 6.2, shall be maintained when the guidance document is
a) expanded by the insertion of additional clauses at the end of the existing framework sections or by
the subdivision of a framework section,
b) translated into other languages, or
c) trimmed (filleted) to suppress clauses not relevant to specific implementation.
A guidance document, being an implementation of this framework, may suppress (sub)clauses within
sections and/or add additional clauses. It may not suppress any of the three framework sections. it is
possible for future revisions of this Technical Specification to incorporate additional clauses to reflect
the increasing scope of the application of BIM.
6.4 Clauses
Clauses, being the “leaf terminal subsections” of the guidance document, shall be written in order to express
the normative objective by the clear expression of requirements, exceptions, applicability and selection.
6.4.1 Objective
Every clause shall have an objective which summarizes the intention and implies the impact of non-
compliance.
6.4.2 Applicability
Every clause shall identify the scope of application. This shall be one or more measures, which
progressively focus on the objects relevant to the objective.
6.4.3 Selections
Any clause may identify the scope of selection. This may be one or more measures, which collectively
widen the focus of objects relevant to the objective.
6.4.4 Exceptions
Any clause may identify the exceptions to the scope. This may be one or more alternative measures,
which eliminate objec
