21、ice life planning, is an essential contribution to the development of a policy for service life planning of buildings and constructed assets.This part of ISO 15686 establishes the basic procedures necessary for the service life planning process of buildings. However, for this to occur it is consider
22、ed that an information system is needed. An information management system suitable for carrying out the service life planning process needs to meet a number of rigorous requirements including being able to capture enough information and support the methods needed to calculate the effect of the envir
23、onment (and microclimate) on the building materials and components used, define maintenance schedules for different qualities of building materials installed under different environmental conditions. apply life cycle costing methodologies using the captured data to calculate the benefits of using ei
24、ther high performance materials with little maintenance or lower performance materials with better maintenance procedures. Procedures need to be able to take ease of replacement and demolition into account, incorporate new knowledge and predictive methods for material performance and maintenance wit
25、hout affecting methods and data structures that enable calculations based on current knowledge, support interoperability between software applications, and be used by designers, constructors, owners, operators and demolishers throughout the construction lifecycle.Practically, this means applying the
26、 technology that is generally being termed Building construction Information Modelling (BIM) systems. BIM and the use of software applications that enable it is becoming a normal way of working within the construction industry. It offers significant benefits including the ability to work with constr
27、uction components and assemblies as objects that encapsulate both shape (in the form of geometric information) and other information about performance, delivery, operation and more. Performance can include information about durability and sustainability metrics. This offers powerful capabilities for
28、 dealing with these key areas of interest at every level from individual component to constructed facility.This standard is particularly concerned with the provision of information for service life planning. It proposes structures for the capture and exchange of service life planning information bas
29、ed on the Industry Foundation Classes (IFC) standard for information exchange and sharing and on the Construction Operations Building Information Exchange (COBie) standard.The standard starts by providing the service life planning context within which it is prepared. Each-subsequent section covers a
30、 stage of the lifecycle of service life information, starting with its measurement and publication, followed by its adjustment in the context of a particular facility and finally its use in whole-life calculations. The annexes summarize the standard properties and provide worked examples of how the
31、data might be used in manual or automated calculations. ISO 2014 All rights reserved vBS ISO 15686-4:2014BS ISO 15686-4:2014Building Construction Service Life Planning Part 4: Service Life Planning using Building Information Modelling1 ScopeThis part of ISO 15686 provides information and guidance on
32、 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 st
33、ructure 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. COB
34、ie 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 construc
35、tion 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 audien
36、ce 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 commo
37、n transactions.This document may be used for a variety of purposesa) 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 ne
38、cessary 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 Mo
39、delling (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 serv
40、ice life data to these objects and make the data available for other purposes through the use of data exchange standards.INTERNATIONAL STANDARD ISO 15686-4:2014(E) ISO 2014 All rights reserved 1BS ISO 15686-4:2014ISO 15686-4:2014(E)Using information exchange standards to describe the structure of se
41、rvice 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 mapThe p
42、rocess 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 summar
43、y, 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
44、 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.Figure 1 Exchange requ
45、irements detailed in this part and their relationship to other partsThe 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/mainte
46、nance).NOTE The data requirements for ISO 15686-7 (In-Use inspection) are used in Clause 7 and Annex B.2 ISO 2014 All rights reservedBS ISO 15686-4:2014ISO 15686-4:2014(E)1.2 Data requirementsThe determination of service life is undertaken at various times during the design, construction and operati
47、on 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, de
48、sign 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 deter
49、mine 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.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 in use conditions. These conditions can vary the reference service life depending on factors such as exposure to weather, aggressiveness of the local environme
