1 Scope
This part of ISO 15686 provides information and guidance on the use of standards for information exchange
for service life planning of buildings and constructed assets and their components
as well as the required supporting data.
It provides guidance on structuring information from existing data sources to enable
delivery of their information content in a structure that conforms to international
standards for information exchange. In particular, reference is made to ISO 16739. The Construction Operations Building Information Exchange (COBie) standard for the exchange of facility information in tabular data are used as an
alternative representation. COBie is a tabular representation of a handover view of the IFC schema.
It is also applicable to the exchange of service life information between categories
of design and information management software applications that have standards-based
information exchange interfaces including:
-
a) Building construction Information Modelling (BIM);
-
b) Computer Aided Facilities Management (CAFM).
Excluded from this part of the standard are
-
— information exchange using proprietary methods, and
-
— processing and analysis of data within individual software applications, though examples are provided.
The main target audience is the Information manager who will use the framework to
assist in structuring the International, national or project/facility level BIM guidance
document.
This Standard specifies the structure and representation of service life data. It
is focused on key exchange requirements underlying the common transactions.
This document may be used for a variety of purposes
-
a) to achieve and maintain a common understanding within the national and project contexts;
-
b) to establish the desired outcomes and to define appropriate quality;
-
c) to identify appropriate management effort and tools;
-
d) to identify necessary effort and resourcing.
Service life planning involves the application of data about elements within a building
or constructed assets to enable their design, predicted or estimated service life
to be determined and communicated. Buildings are increasingly designed using Building
Information Modelling (BIM), an approach that can provide a specification of all the
objects in building and how they are aggregated into parts, assemblies and systems. An architect
or engineer can define the objects using BIM; it is anticipated that the actor having the service life planning role
will apply service life data to these objects and make the data available for other purposes through the use of data exchange standards.
Using information exchange standards to describe the structure of service life planning
information is important because it normalizes the way in which service life information
should be delivered from source to user so that relevant different attributes can
be exchanged and a range of software applications can be used to capture the information.
1.1 Process map
The process map (see Figure 1) shows the key sequence of information exchanges and places the information exchanges
in context, identifying the sending and receiving roles. It is based on the process
map for design given in ISO 15686‑1:2011, Annex B, and the management plan given in ISO 15686‑3.
In summary, ISO 15686‑2, ISO 15686‑8, ISO 15686‑5 and ISO 15686‑7 define four processes which use service life data.
-
— ISO 15686‑2 (Testing): Product and testing are brought together to obtain the service life characteristics.
-
— ISO 15686‑8 (Prediction): The characteristics are brought into a specific context to obtain a predicted service life.
-
— ISO 15686‑5 (Costing): The predicted or measured service life is used with cost or environmental impact rates to obtain a life cycle cost or assessment.
-
— ISO 15686‑7 (In-use inspection): The context factors are revised to reflect in-use surveys.
The process map document covers the determining of the service life of a type of product
(during early design stages) and of occurrences of products of a particular type (during
later design stages, construction and operation/maintenance).
NOTE The data requirements for ISO 15686‑7 (In-Use inspection) are used in Clause 7 and Annex B.
