What Is Jump Formwork and How Does It Work?

TL;DR

Jump formwork is a construction technique for tall structures that supports vertical concrete elements like shear walls and lift shafts. It allows for fast construction and high-quality finishes by minimizing crane time and labor. The method includes various types such as normal jump, guided climbing jump form, and self-climbing jump form, each with unique benefits for high-rise building projects.
