Work inputs and related economic aspects of multitier shoring towers

Shoring towers are the common formwork solution for high-clearance construction. Because towers account for a remarkably high percentage of the cost of the constructed concrete element, work input data and related economic aspects of tower erection constitute important information for constructors. This paper presents three case studies of high multitier shoring towers, each representing a different tower type. Tower data, major construction parameters, and work inputs for each case are presented. Findings are compared and discussed, and due conclusions are drawn. Finally, recommendations on measures expected to increase the economy of shoring solutions using multitier towers are offered, and some restrictions on the adoption of work input data are listed.
