Construction related factors inè uencing the choice of concrete è oor systems
2002
Designers have a wide choice of concrete e oor systems for their buildings. They can choose from three basic types available: in situ, precast or hybrid construction. A survey was conducted within the UK construction industry to investigate, in particular, the construction related factors ine uencing the choice of concrete e oor systems. The data collected were subjected to frequency and severity index analyses, Kendall’s concordance test and the chi-squared tests to produce a rank ordering of 12 construction related factors. Five factors were identie ed as being the most important, namely ‘appropriateness of use’, ‘cost’, ‘constructability’, ‘speed’ and ‘health and safety’. These e ve factors ree ect current industry emphasis, and therefore could be adopted as the principal criteria for evaluating and selecting concrete e oor systems during the design stage. They could also be used as assessment criteria for developing future systems.
