Improving Structural Safety in the Alteration and Refurbishment of Old Buildings

摘要

Building alteration and refurbishment continue to dominate the construction activities in the UKrnand many developed economies. This is because the need to upgrade older buildings to achievernbetter functional usage and energy (or even) structural performance standards are continuouslyrnrequired. However, due to the fact that in many cases, such older buildings usually have very littlerninformation available on the as-built (or historical modification) status; there is a need to plan thernproposed works effectively to ensure that health and safety is not compromised in any way.rnStructural safety must be assessed before, during and after the works and the need to incorporaternthis into the work programme is highly essential. This research examines some recent projects inrnthe UK where the author was consultant structural engineer and researcher. It explores the methodsrnused to ensure that structural safety is achieved throughout the works. These principles werernincorporated into the project cycles involving the: brief, initial assessment, initial design, initial striprnout, construction stage 1, complementary designs, construction stage 2 and project completion andrnhand over. This strategy is innovative as it facilitated an integrated and systematic approach to thernuse of risk assessment for structural safety in the light of the dynamic nature of constructionrnrefurbishment sites. Key learning points are discussed with a view to contribute to knowledge andrnengender wider debate in the development of current Guides and Approved Codes of Practice.rnIssues for further research are also highlighted.
