Design for Maintainability - Application Guides S.

Building services systems require maintenance from the moment they are put into operation until the end of their operating lives. The cost of system maintenance has been demonstrated to represent a significant proportion of the total building operating costs, possibly on a par with the cost of utilities (energy and water).;Cost savings can be made over the life of an installation if proper attention is given to maintenance aspects during the design of a system. It is often the case that maintenance is a relatively low priority for the designer. However, many of the basic design features which can have a considerable impact on maintainability are often relatively simple to implement and can easily be shown to result in significant savings.;This guide aims to demonstrate, for each stage in the design process, how maintenance aspects should be considered, justified and implemented. It has been produced in conjunction with BSRIA "Technical Notes TN10/92, Space Allowances for Building Services Distribution Services - detailed design stage".
