The temporary support of a structure, excavation, or trench, achieved through the use of shores, is a critical aspect of construction safety and stability. These shores, typically constructed from timber, steel, or aluminum, are designed to bear loads that the existing structure or soil cannot safely handle on its own. For example, during the demolition of a load-bearing wall, a system of vertical and horizontal supports would be erected to transfer the weight to adjacent structural elements, preventing collapse.
This process is vital for preventing structural failure and protecting workers from injury during construction, demolition, or repair projects. Its application ensures the integrity of buildings, excavations, and other structures, particularly when existing elements are compromised or removed. Historically, rudimentary forms of this support were employed in mining and early construction projects, evolving into more sophisticated engineering solutions with the advent of new materials and calculation methods.
