ONE Tower Limassol will be the tallest building in Cyprus reaching 37 stories. SEAMLEXITY addressed a number of challenges concerning the complex geometry of the building. Among these, the concrete structure and building envelope have been rationalised and the geometric references have been redefined. Following the involvement of the committed sub-contractors, SEAMLEXITY has provided a comprehensive clash detection process and modelling audit services using BIM tools. Our specialist software provided precise setting out information to the projects consultants and contractors.
