De Brug (‘The Bridge’) consists of a four storey office building, each with a surface covering approximately 130 by 30 metres. The bottom one of these four storeys rests 35 metres above ground level, directly above the existing Unilever industrial complex. The total floor area amounts to 15.700m2 GFA.
The building is constructed as a steel structure combined with a steel plate concrete floor. Because the building rests on as little as three supports, the façades require large steel lattices. These give the building the appearance of an old-fashioned bridge structure, to which the building owes its name: ‘De Brug’, or ‘The Bridge’ in English. To minimize the steel structures’ proportions, lightweight concrete has been preferred over gravel based concrete as a pressure distribution layer on the steel plate concrete floor. A low-vibration and soil-displacing pile driver system has been used to lay the building’s foundations.
