Provides guidance on durability, required and predicted service life and design life of buildings and their components and/or parts. Applies to new buildings and their components and/or parts rather than to alterations and repairs. Applies to civil engineering projects involving buildings, but only partially to other civil engineering projects such as roads, bridges and dams. Does not deal with many aspects of obsolescence. Covers introduction, definitions, requirements for durability, predictions of durability, design life of buildings and components and expression of durability. Includes appendices, tables and figures.
