This article contains the previous calculations and preparatory works for the covering of the Arena of Valladolid with a penumatic dome in the shape of a segment of a sphere, made out of polietilene membrane and radial "perlon" ribbons reinforcement. The objective of the dome being the temporary covering (10 days) of the Building Techniques and Materials Show (CONSTRUVALL-89) organized by the School of Architecture students at the University of Valladolid In March 1989. The works for the making up of the dome are also described as well as the attempt for its inflation that, unfortunately, failed due, above all, to the bad weather conditions of those days.
