From the time that it was established in 1953, ABT's approach has been characterised by striving for 'representative structures and doable architecture'. On the basis of giving content to the concept of 'integrated design'. In order to arrive at a feasible project within the limiting conditions of time and cost, ABT evolved at an early stage into a multi-disciplinary engineering practice. In 1965 a number of structural consultancy areas were added to the building consultancy.
ABT has now expanded into a pioneering engineering practice, with branches in Velp, Delft, Düsseldorf and Antwerp, that provides a complete range of structural services from both a building and a design aspect.
