- ISO 15686
ISO 15686 is the in development ISO standard dealing with
service life planning. is a decision processwhich addresses the development of the service lifeof a building component, buildingor other constructed work like a bridgeor tunnel. Its approach is to ensure a proposed design lifehas a structured responsein establishing its service life normally from a reference or estimated service life framework. Then in turn secure a life-cycle cost profile(or wholelife costingwhen called for) whilst addressing environmental factors like life cycle assessmentand service life careand end of life considerations including obsolescenceand embodied energyrecovery. Service life planningis increasingly being linked with sustainable developmentand wholelife value.
The objective of service life planning is to provide
reasonable assurancethat the estimated service life of a new building on a specific site, with planned maintenance, will be at least as long as the design. Service life planning facilitates the making of well-informed decisionsregarding value engineering, cost planning, maintenance planning, and environmental impact. As service life cannot be estimated precisely, the objective requires the making of an appropriately reliable estimate of the service life of the building using available knowledgerelating to the service life of each material, component, assembly, and systemthat is to be used in the building.
If the estimated service life of any of these is likely to be less than the
design lifeof the building, a decision should be made as to whether maintenance, repair, or replacementcould ensure that its essential functionscould be adequately maintained. To assist with specificationand design, and avoidance of obsolescenceand waste, service life planningmay include projections of the needs for, and timing of replacement and end of life recovery.
15686 for service life planning is being prepared by
Technical Committee ISO/TC 59, Building construction- Subcommittee SC 14, Design life.
In Great Britain, the new British Standard BS ISO 15686-5:2008 Buildings and constructed assets. Service life planning is currently being launched (September 2008). The life cycle costing standard and the additional Standardized method of life cycle costing for construction (SMLCC) provide an in-depth guide to life cycle costing, an area of increasing importance. The
BSIexplains that "the UK building industry recognizes that life cycle costing (LCC) is necessary and important, but confusion exists about the best method to realise the economic and environmental benefits of such costing".
