In precast construction industry there are many one-way prestressed or steel-concrete composite structural systems. However, due to transportation limitations there are almost no solutions that may provide two-way action. This article describes an innovative prestressed partially precast structural system for construction of two-way slabs that allows long-spans and high span-to-depth ratios. Since the system was developed in 2003, more than 250,000 m2 of civil and residential structures have been built.
