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.<\/p>\n
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.<\/p>\n
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:<\/p>\n
Building construction Information Modelling (BIM);<\/p>\n<\/li>\n
Computer Aided Facilities Management (CAFM).<\/p>\n<\/li>\n<\/ol>\n
Excluded from this part of the standard are<\/p>\n
information exchange using proprietary methods, and<\/p>\n<\/li>\n
processing and analysis of data within individual software applications, though examples are provided.<\/p>\n<\/li>\n<\/ul>\n
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.<\/p>\n
This Standard specifies the structure and representation of service life data. It is focused on key exchange requirements underlying the common transactions.<\/p>\n
This document may be used for a variety of purposes<\/p>\n
to achieve and maintain a common understanding within the national and project contexts;<\/p>\n<\/li>\n
to establish the desired outcomes and to define appropriate quality;<\/p>\n<\/li>\n
to identify appropriate management effort and tools;<\/p>\n<\/li>\n
to identify necessary effort and resourcing.<\/p>\n<\/li>\n<\/ol>\n
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.<\/p>\n
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.<\/p>\n
1.1<\/b> Process map<\/p>\n
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.<\/p>\n
In summary, ISO 15686-2, ISO 15686-8, ISO 15686-5 and ISO 15686-7 define four processes which use service life data.<\/p>\n
ISO 15686-2 (Testing): Product and testing are brought together to obtain the service life characteristics.<\/p>\n<\/li>\n
ISO 15686-8 (Prediction): The characteristics are brought into a specific context to obtain a predicted service life.<\/p>\n<\/li>\n
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.<\/p>\n<\/li>\n
ISO 15686-7 (In-use inspection): The context factors are revised to reflect in-use surveys.<\/p>\n<\/li>\n<\/ul>\n
Figure 1<\/b> Exchange requirements detailed in this part and their relationship to other parts<\/p>\n
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).<\/p>\n
\nNOTE The data requirements for ISO 15686-7 (In-Use inspection) are used in Clause 7 and Annex B.<\/p>\n<\/blockquote>\n
1.2<\/b> Data requirements<\/p>\n
The determination of service life is undertaken at various times during the design, construction and operation of a project. During the early design stages when product information is aggregated a level such as the whole building or as specifications of whole systems; it is only the design life of a product that can be determined. At the earliest design stages when only product occurrences are defined, design life is estimated at the occurrence level. At later design stages, when individual products are located and these products are designated by type, design life can be indicated for all occurrences at the type level. Similarly, when individual products are identified, it becomes possible to determine a reference service life when a manufacturer\/supplier can be identified. As with design life, reference service life can be allocated to the product type level.<\/p>\n
At later design stages and during construction, when the configuration and location of products has been fully established, it becomes possible to analyse the service life of products according to \u2018in use\u2019 conditions. These conditions can vary the reference service life depending on factors such as exposure to weather, aggressiveness of the local environment and other degrading (or upgrading) factors. The result of applying in-use conditions is to define an estimated service life which is simply the length of time of a product occurrence lifecycle.<\/p>\n
Finally, the condition of a product occurrence can be checked from time to time during the operational stage. From the condition of the product, a residual service life can be assessed. If degradation is more than has been expected, the residual service life is reduced to less than the value that might have been expected from the estimated service life.<\/p>\n
The overall data requirements for the process are summarized in Figure 2.<\/p>\n

Clause 4 of this part of ISO 15686 defines the data requirements to identify the product.<\/p>\n
Clause 5 suggests the data required for the specification\/selection of product.<\/p>\n
Clause 6 adds the testing regimen and the key service life metrics.<\/p>\n
Clause 7 adds the context and the predicated estimated service life.<\/p>\n
Clause 8 adds the impacts (to date and predicted) for stages in the life cycle value.<\/p>\n
Clause 9 suggests a representation where uncertainty and ranges of values are relevant.<\/p>\n
Annex A provides a formal representation for Service Life definition.<\/p>\n
Annex B provides a formal representation for Service Life factors.<\/p>\n
Annex C provides a formal representation for Environmental and Economic Impact measures.<\/p>\n
Annex D offers example calculations.<\/p>\n
1.3<\/b> IFC support for service life planning<\/p>\n
IFC contains support for a wide range of building and construction topics. The information needed for service life planning and related topics is supported by specific objects (entity types) in the schema (e.g. an object handling functional measures’), but also as general objects handling the technical performance of building components and systems, property information (e.g. material) about the building components, information about needed measures of care and maintenance etc.<\/p>\n
There are several concepts captured in the IFC schema that are relevant to service life planning and that can be applied in a specific subset (view) of the IFC schema about service life planning. These include the following. See Table 1.<\/p>\n
