During past decades, the design of multi-storey precast concrete structures has developed into an attractive alternative to cast in situ and steel structures. The present Recommendations aim to guide designers toward solutions and considerations that past experience has shown to be successful. Moreover, owners and investors are informed of the additional advantages and qualities that can be achieved by using precast concrete in accordance with current practice. By following these Recommendations, errors made in the past can be avoided.

To establish the state of the art, the Working Party of the FIP Commission on Prefabrication circulated two questionnaires: a preliminary questionnaire in Belgium and the Netherlands, the results of which were presented in FIP Note 88 (1980), and later a revised questionnaire distributed internationally. In addition, the Working Party co-opted a number of corresponding members from various countries.

The conclusions presented in these Recommendations are therefore supported not only by building technologies that have evolved over time in different countries, but also by the expertise of those involved in their continued development. Since the detailing of connections, for example, often varies from country to country due to local practices or codes, the reader should bear in mind that the details given in this publication are intended only as examples of possible approaches. However, it is clear that the general quality of a precast building structure depends on the selection of appropriate layouts, structural units, and connection principles, and that sound planning and construction procedures are universally applicable.

The Chairman of the Working Party was Mr. J. N. J. A. Vambersky, Ingenieursbureau Ir. E.J.A. Corsmit BV, Frankenslag 32, 2582 HS The Hague, the Netherlands, who welcomes any comments or criticism on these Recommendations.
