Le système de coffrage auto-grimpant indépendant peut comprendre une pluralité de tours de support. De plus, au moins deux fermes peuvent être reliées à la pluralité de tours de support. Les fermes peuvent être espacées les unes des autres. En outre, une ou plusieurs plateformes peuvent être formées à l'intérieur d'un périmètre délimité par les au moins deux fermes. La ou les plateformes peuvent être conçues pour s'étendre ou se rétracter à l'intérieur du périmètre. En outre, des vérins à vis peuvent être disposés au niveau de chaque point de raccordement des au moins deux fermes sur la pluralité de tours de support. Les vérins à vis peuvent être conçus pour déplacer verticalement les au moins deux fermes vers le haut et vers le bas de la pluralité de tours de support.
