If construction speed is a priority when you build a tall concrete structure, slipforming may be the answer. Slipforming differs from conventional concrete forming because the forming panels move semicontinuously in relation to the concrete surface being formed and form ties are not used.
Improvements in this advanced construction technology have made large projects even more economical than ten years ago; larger yoke capacities and better laser guidance systems result in more efficient and faster slipping rates.
Traditionally used to construct high-rise building cores of at least 25 to 30 stories, vertical slipforming in recent years has been used primarily for agricultural structures, such as storage silos and feed plants, and for very large offshore oil platforms.
