19 Category 1: Buildings 1 RAI Hotel - Amsterdam, Netherlands Owner COD Architect OMA General Contractor Pleijsierbouw Engineering Office Van Rossum Raadgevende Ingenieurs Construction Period 2016 - 2018 In Amsterdam, the biggest hotel of the Benelux is being built next to the RAI Amsterdam, conference hall, with 650 hotel rooms. The building is a tower of 91 metres in height, with triangular volumes cantilevering out from the structural core in the centre of the building. The main load-bearing structure consists of a concrete core, with walls cantilevering from the core. A secondary steel structure is designed to make the second cantilever for the façade. The farthest point of the floors makes a cantilever of 23 metres to the core. During the initial design phase, SCIA Engineer gave us the possibility to make quick parametric studies to make comparisons between different structural options and show the feasibility of the structural design with regards to the special architecture of the building. SCIA Engineer was used to perform a stability calculation, including the determination of eigenfrequencies and accelerations. Moreover, internal forces in all the structural elements in the building were calculated with SCIA Engineer. The SCIA Engineer’s output of the concrete forces was directly used to determine the reinforcement in the concrete core. 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.
