Furthermore, such an effective and proactive Management System purports that the integration between the climbing concrete forming machines and the concrete pumping, pouring and placing devices must be achieved. First of all, the methodology adopted by the Research Unit required to perform a comparative analysis, in close co- operation with the Leading World Manufacturers, through the investigation of the most effective managerial and technical available options. Furthermore, the investigation performed by the Research Unit took into account some meaningful case-studies (located in Germany, Italy, Spain, Sweden, and Switzerland). The main conclusion lies with the need for distinguishing amongst different kinds of High-rise Tower (depending on its heights and shapes) and the preferred models of Site Management to be followed. Keywords: high-rise towers, site management, formworks, concrete pumping system. 1 1. The formwork and steel fixing systems In Italy, the poor performances and the lack of managerial skills affecting the construction sites are due to an absence of the co-operation amongst the various Players (Client Organizations, Main Contractors, Sub-Contractors, and Suppliers). Indeed, quite often it happens that a Public or Private Client Awarding Organization seems to neglect the Site Management-oriented topics. Likewise, the Main Contractor does not want to be really involved into the Site Management-related solutions, preferring to leave the choice of the preferred formwork, steel fixing and pumping systems to its first- tier Sub-Contractors.
