Analysis of construction sub-processes for the evaluation of the real performance of tower cranes

Abstract The productivity of work performed at construction sites is primarily dependent on the effective deployment and use machinery. Nevertheless, manufacturers do not state actual performance their machinery because it difficult to determine due its dependence specific conditions present each site. One most important machines used in buildings tower crane, which provides secondary transport material onsite. In order evaluate effectiveness such using a deterministic or stochastic approach, relatively extensive exact set data describing activities given crane needs be prepared. These describe real requirements ongoing sub-processes with regard utilisation cranes. This contribution concerns analysis key during building monolithic reinforced concrete structures connection site; particular, describes preparation processing this for evaluation time placed
