propping

Propping refers to the provision and arrangement of temporary supports or props to hold, brace, or elevate a load, structure, or object during work or use. It is used across industries including construction, architecture, theater, and film, and may involve timber, steel, or hydraulic systems.

In construction and civil engineering, propping supports formwork, beams, or slabs during erection, shoring, or repairs. Common devices include timber standards, adjustable steel props, hydraulic jacks, and screw jacks. Propping requires calculations of load, spacing, and duration, with bracing and redundancy to prevent sudden collapse, and routine inspections.

In theatre and film, propping refers to the management of props—objects used by actors or on set. A prop master sources, maintains, and assigns props, ensuring safety, durability, and continuity with the script and design. Some items are life-size, some are fragile, and many require special handling or safety protocols for weapons or hazardous materials.

Safety and standards: Propping is governed by local safety regulations and industry guidelines. Key practices include proper load assessment, securing against tipping, clear access for workers, and prompt removal of temporary supports after the work is done. Inappropriate propping can lead to structural failure or hazards to personnel.

The use of propping is context-dependent, and practices are tailored to the specific requirements of each field. Related concepts include shoring and formwork in construction, and prop management in theatre and film.
