Today construction industry is building higher and more complicated constructions than ever thanks to the advancements in materials, technical knowledge and methodologies. One important material is concrete, which has been used to create impressive architectural marvels. This dissertation aims to examine the differences between climbing and slip formwork systems for tall concrete structures that require several pouring steps in height. The main differences noted between both systems are formwork configuration, assembly and cycling of the formwork and climbing elements, price and quantity of material, labor required, the quality of the finished structure and safety during construction. A case study was investigated with the help of formwork supplier PERI Sverige AB and nordic contractor PEAB AB regarding a 20,5 meter high reinforced concrete silo located in a mining complex in Kiruna, Sweden. Through a review of the existing literature in the subject, interviews with experts in the topic and the outcome from the project case study, the results shows that while the SCS climbing system from PERI Sverige AB required more working days compared to a slip formwork system, it was chosen as a more appropriate solution for this project in combination with the crane at the jobsite, due to the amount of labor required, safety and overall cost of it. In conclusion, the selection of the SCS climbing system as formwork system proved to be the most adequate solution for the case study when critical aspects such as assembly and cycling of formwork, price and safety were evaluated.
