Building information models - Information delivery manual - Part 1: Methodology and format (ISO 29481-1:2016)

ISO 29481-1:2016 specifies
-      a methodology that links the business processes undertaken during the construction of built facilities with the specification of information that is required by these processes, and
-      a way to map and describe the information processes across the life cycle of construction works.
ISO 29481-1:2016 is intended to facilitate interoperability between software applications used during all stages of the life cycle of construction works, including briefing, design, documentation, construction, operation and maintenance, and demolition. It promotes digital collaboration between actors in the construction process and provides a basis for accurate, reliable, repeatable and high-quality information exchange.

Modèles des informations de la construction - Protocole d’échange d’informations - Partie 1: Méthodologie et format (ISO 29481-1:2016)

L'ISO 29481-1:2016 spécifie:
-      une méthodologie qui relie les processus métier employés pendant la construction d'installations à la spécification des informations requises par ces processus; et
-      un moyen de cartographier et de décrire les processus d'information sur tout le cycle de vie des travaux de construction.
L'ISO 29481-1:2016 est destinée à faciliter l'interopérabilité entre les applications logicielles utilisées à toutes les étapes du cycle de vie des travaux de construction, dont la préparation, la conception, la documentation, la construction, l'exploitation et la maintenance, ainsi que la déconstruction. Elle promeut la collaboration numérique entre les acteurs du processus de construction et donne une base pour un échange d'informations précis, fiable, répétable et de haute qualité.

Informacijski modeli stavb - Priročnik z informacijami - 1. del: Metodologija in oblika (ISO 29481-1:2016)

Standard ISO 29481-1:2016 določa:
– metodologijo, ki povezuje poslovne postopke, izvedene med gradnjo obratov, z navedbo informacij, ki jo ti postopki zahtevajo, in
– način za povezovanje in opisovanje informacijskih postopkov prek celotnega izvajanja gradbenih del.
Namen standarda ISO 29481-1:2016 je poenostaviti interoperabilnost med programskimi aplikacijami, ki se uporabljajo v vseh fazah gradbenih del, vključno s poročanjem, načrtovanjem, dokumentiranjem, gradnjo, upravljanjem in vzdrževanjem ter rušenjem. Spodbuja digitalno sodelovanje med udeleženci v gradbenem postopku ter zagotavlja podlago za natančno, zanesljivo, ponovljivo in visokokakovostno izmenjavo informacij.

Introduction

This International Standard has undergone a major review in the light of refined approaches to the

development of information delivery manuals and their technical implementation in software readable

forms. It is important to note that these changes do not render existing information delivery manuals

(IDM) invalid.

Building information modelling provides a digital technology for describing and displaying information

required in the planning, design, construction and operation of constructed facilities. Increasingly,

this modelling approach is expanding to encompass all aspects of the built environment, including civil

infrastructure, utilities and public space. These are collectively referred to as construction processes.

This approach to managing information brings together the diverse sets of information used during

the life cycle of the built environment into a common information environment, reducing, and often

eliminating the need for the many types of paper documentation currently in use.

This approach is commonly referred to as building information modelling (BIM; reflecting its initial

application in the architectural domain), while the same acronym is used to refer to the product of the

process, the information model itself, or building information model (BIM).

Though the focus of construction processes described above is on the physical fabric of the built

environment, BIM technology can also benefit the processes associated with managing the use of

space within buildings, urban neighbourhoods and cities at the broader scale, as well as infrastructure

networks and facilities. These are referred to here as use cases.

An IDM provides help in getting the full benefit from a BIM. If the required information is available in

the BIM to support a construction process or use case, and the quality of information is satisfactory,

then the process itself will be greatly improved.

For this to happen, there needs to be a common understanding of the processes involved across the

entire life cycle development of a built environment project, including the information that is required

for and results from the execution of that process. This applies to any activity that results in an

exchange of information and may not relate directly to a BIM, e.g. the process to arrive at a work plan or

contractual agreement.

This part of ISO 29481 sets out a methodology for the provision of an integrated reference document

that describes the processes and data required in the development or management of a constructed

facility. It describes how to identify and describe the processes undertaken within that context, the

information required for their execution and the results. This part of ISO 29481 also describes in

general terms how this information can be further detailed to support solutions provided by software

developers, enabling its reuse, and configured to meet national, local and project needs.

In summary, this part of ISO 29481 provides a basis for reliable information exchange/sharing for users

so that they can be confident that the information they are receiving is accurate and sufficient for the

activities they need to perform. The development of this part of ISO 29481 has been driven by the need

of users for reliability in information exchange.

Part 1:
Methodology and format
1 Scope
This part of ISO 29481 specifies

— a methodology that links the business processes undertaken during the construction of built

facilities with the specification of information that is required by these processes, and

— a way to map and describe the information processes across the life cycle of construction works.

This part of ISO 29481 is intended to facilitate interoperability between software applications used

during all stages of the life cycle of construction works, including briefing, design, documentation,

construction, operation and maintenance, and demolition. It promotes digital collaboration between

actors in the construction process and provides a basis for accurate, reliable, repeatable and high-

quality information exchange.

4 Information delivery manual
4.1 General

This Clause describes a series of concepts and principles that inform the development of an IDM.

4.2 Users of this part of ISO 29481

The main users are expected to be the IDM developers who create interaction maps, process maps,

exchange requirements and information constraints using knowledge elicited from end users and

solution providers.

In addition, some users of specific IDMs might identify needs for new IDMs and thus become users of

this part of ISO 29481. These users include the following:
— professional IDM-developers and solution providers;

— information users, i.e. executive users and end users concerned with producing the content of the

IDMs and benefiting from the result.

---------------------- Page: 15 ----------------------
SIST EN ISO 29481-1:2017
ISO 29481-1:2016(E)

Another group of users will be those who use the documentation that results from the use of the

standard, taking note of the business process and detailed specifications of the information that a

user fulfilling a particular role would need to provide at a particular point within a project. Such users

include the following:

— project manager, responsible for organizing the business process and ensuring that the information

exchange is appropriately managed;

— BIM manager, making the necessary arrangements to support an exchange requirement;

— client, who initiates (develops) and includes an IDM in the contract;

— contractor/consultant, using the IDM to make the necessary arrangements to comply with the

required business process and to comply with the required information delivery;

— business manager, using an IDM as a template or standard to be applied in many projects within its

organization;

— construction organization, using an IDM for a specific project type as a template or standard to be

applied in the sector.
4.3 Business context

Figure 1 shows an example of a business context that requires an IDM: a client (Role 1) engages

a consultant (Role 2) to deliver some service. In such a scenario, there is a need to understand and

formalize both the collaborative and contractual aspects of their relationship and how information will

be delivered within that context. The IDM describes the information requirements associated with all

the transactions (both ways) associated with that relationship. Some of that information will be held

within a BIM, while other may originate from either party or from an external source.

Figure 1 — Example of a simple business context requiring an IDM

The first step in developing an IDM is to consider the nature or context of the information exchange.

There are two ways of looking at that, each with an associated methodology.

— Process maps are most useful when the focus is on the business processes (defined by activities

executed by actors with roles) that need to be followed to deliver a service or produce an end

product (such as a design). In this case, the information that is the focus of the IDM is associated

with a business requirement.

---------------------- Page: 16 ----------------------
SIST EN ISO 29481-1:2017
ISO 29481-1:2016(E)

— Interaction maps/transaction maps are most useful within a business process when the focus is on

the interactions between actors with roles who are to deliver a service or product and the concern

is to ensure that agreed communication protocols are in place to ensure that the project goals are

achieved. In this case, the information that is the focus of the IDM is associated with a transaction.

These are complementary approaches and are explained in further detail in later sections. Within a

given business context, it may be appropriate to use both methodologies: process mapping can be used

to clarify the details of a transaction identified in an interaction mapping exercise, while an interaction

map can be used to rigorously understand an information transaction defined in a process map.

4.4 Complete schema

Where the information requirements are satisfied by a BIM, a complete information schema that covers

all of the information required for all actors throughout the construction process will be large and

comprehensive. Such a schema is relevant in defining all of the project information needs for all business

processes at all life cycle stages, but it is not the way that project information is usually delivered.

4.5 Breaking a complete schema to support requirements

It is more usual for information to be exchanged about a particular topic and the level of detail provided

to be driven by the life cycle stage. This may be a single business process at a specific point in the

project life cycle, but commonly consists of information units that may be relevant to more than one

life cycle stage or business processes. This is commonly
...
