After winning the tender, the architect approached Van Rossum for further development of the project. The building comprises two parts: a low-rise and a high-rise section. The design was created for the high-rise with prefab inner walls and a load- bearing prefab exterior wall. This enables the construction speed of one story per week. The bridge construction between both towers comprises of four steel lattice trusses and a secondary load-bearing structure safeguarding these trusses. The trusses are designed in such a way that each joist can be eliminated without causing the rest of the construction to fail. In order to prevent the lattice trusses being jammed between both towers, a pure hinge system was designed as a support. During the design phases of the project, SCIA Engineer allowed us to quickly review different alternatives for the structural design. During a short period of a few weeks, different stability systems were taken into account, resulting in an optimal combination of structural inner walls and a structural facade. In the final phases, an accurate calculation of internal forces of all structural elements was carried out in SCIA Engineer. This calculation is both used by us as the main structural engineer to design the elements and by the sub- contractors to calculate their individual elements. Van Rossum Raadgevende Ingenieurs Contact Marjan Kluft Address Pedro de Medinalaan 3a 1086 XK Amsterdam, Netherlands Postbus 37290 1030 AG Amsterdam, Netherlands Website www.vanrossumbv.nl Van Rossum is characterised as a creative solver; a construction adviser who knows that many integral solutions are only possible with the knowledge from the other construction fields. Choices made at the start of the design process have a major influence on construction costs and quality. In the first stage of a project in particular, we can exert defining influence on efficiency within the process. It is therefore important to start the process with a top design team that maintains 100% communication. We act as advisers to our clients and are able to make a clear economic constructive concept. Guaranteeing the feasibility of project.
