78 Used software: Scia Engineer, ESA-Prima Win Introduction The ambitious inner city renewal project “Rond de Admirant” is located on the Emmasingel, near two monumental buildings: the former Philips head office “De Bruine Heer” (“The Brown Gentleman”), and the former factory site “De Witte Dame” (“The White Lady”). The Italian architectural firm Massimiliano Fuksas Architetto was asked by the developer to design the “De Witte Dame” plan. The building’s shape resembles a (half-) droplet, or egg; the largely transparent glass façade shows the occasional indentation. This modern architectural design - known as BLOB (BiLinear OBject) – has caused quite a stir in Eindhoven. Because of the building’s shape, the floor space decreases with each storey (measuring 1000 m2 on the ground floor, and only 200 m2 on the 4th floor); also, the 2nd, 3rd and 4th floors have large voids, stretching out to the façade. The steel construction is non-bearing, because of the glass façade; the concrete framework (floors, walls and columns) are therefore self-supporting. The framework also provides for stability, whereas the glass façade is only supported horizontally on storey-level. Design The concrete skeleton was designed as a 3-D model with the use of Scia Engineer. The ground- and 1st floor are to be used as store locations, therefore, the principal insisted on relatively large spaces between the columns (maximum of approximately 9 metres). At the same time, the architect demanded similar edge distances on each floor, compared to the superjacent (curved) floor framing. Because of these demands, hardly any column is placed directly above another, and every floor level (concrete floor, d = 400) is constructed as a transition slab (with high concentrations of punching stress and shear forces here and there, as well as flexural moments). Entrance building “De Admirant” Eindhoven The grand finale of the vast inner city renewal project by ‘Rond de Admirant CV’ (Heijmans Real Estate) consists in the construction of a striking and futuristic building. The works started in October 2008 and the architectural name used for this construction is known as BLOB (BiLinear OBject). Both the non-bearing (glass) façade construction and the concrete framework were designed en dimensioned by ‘IMd Raadgevende Ingenieurs’, using the 3-Dimensional computational software package Scia Engineer. By using this computational software, the required material quantity was minimised, while the construction process was optimised.

At present the firm consists of 40 highly educated employees. IMd is completely independent and does not have any business links with manufacturers, suppliers, contractors, developers and other interested parties who could influence our impartial and independent consultancy. IMd is a member of the Dutch association of consulting engineers (ONRI) and possesses the “quality management system” certificate according to NEN-AND-ISO 9001. It is a firm where the internal communication proceeds smoothly and all employees are kept informed about the most recent developments. In the almost 50 years that our firm has existed the quality of our service has always been a key issue. The most important characteristics of this service for us are: • A good product that fits the budget of the client • Aproduct that fits the concept of the architect • Creativity and ingenuity • A flexible and service-oriented attitude Projects They vary greatly: from prestigious office complexes to pedestrian bridges, from houses to complex shopping centres, from alterations to new-housing and from simple and small to complex and large. Each project has its own charm and is a constructive challenge. The projects are carried out at the request of property developers, government organisations, foundations, architects, contractors and private parties. This diversity in clients is made possible because of the independence of the firm of consulting engineers. View IMd Raadgevende Ingenieurs The view of IMd is that the success of a project largely depends on the first stage of the design process. The cooperation between architect, client, mechanical engineer and structural engineer is decisive in order to have a fine design in complex projects. In the preliminary design various alternatives are presented for the structure of a building. The advantages and disadvantages of every constructive alternative will then be discussed in the design team. Wishes of the client and architect, requirements in the field of building physics, possibilities regarding the technical installations: they all affect the choice of an optimal structural design. In addition to the constructive design, IMd regards its role as a coordinating engineer as very important. In its existence IMd has built up a perfect reputation. In addition to the inspection of the basic principles of the drawings and calculations of suppliers of prefabricated concrete and steel constructions, the content of these elements is also assessed with great care. We ask the client to make it possible for us to carry out the consultancy work in a constructive way. In the end this will create the best result for the client.
