Logistics of materials handling methods in high rise in‐situ construction

Results of an international investigation concerning the selection of materials handling methods for high rise in‐situ concrete buildings by contractors’ planning engineers in France, Germany and the UK are presented. Findings indicate that materials handling methods differ in each international location. Tower cranes still dominate for high rise in‐situ concrete buildings, although contractors will also frequently utilise concrete pumps in conjunction. Company size has little impact on the materials handling method selected. Eight predominant (construction method) selection factors are identified, and ranked for each international group of contractors. Statistically, the rankings are shown to be almost the same for each country. Relative costs, speed of construction, and site safety are the principal selection criteria. Correlation analysis reveals a degree of association between the selection factors.
