  • ISO 15686 is the in development ISO standard dealing with service life planning. It is a decision process which addresses the development of the service life of a building component, building or other constructed work like a bridge or tunnel. Its approach is to ensure a proposed design life has a structured response in establishing its service life normally from a reference or estimated service life framework. Then in turn secure a life-cycle cost profile whilst addressing environmental factors like life cycle assessment and service life care and end of life considerations including obsolescence and embodied energy recovery. Service life planning is increasingly being linked with sustainable development and wholelife value. The objective of service life planning is to provide reasonable assurance that 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 decisions regarding 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 knowledge relating to the service life of each material, component, assembly, and system that is to be used in the building.
