What are Deadman in construction terminology?

• A. Lightweight panels used for formwork
• B. Weighted concrete blocks with attachment points for tieback anchors
• C. Temporary scaffolding supports
• D. Bracing systems for roof structures

Answer: (B)

In construction terminology, deadmen refer to weighted concrete blocks that have attachment points for tieback anchors. These are used to provide stability and counterbalance forces in various construction scenarios, especially when dealing with excavation or slope stability. The purpose of a deadman is to securely anchor elements of a construction project, such as temporary walls or shoring systems, ensuring that they remain in place under lateral loads.

When tieback anchors are installed, they often require an opposing force to prevent movement or collapse of the wall or excavation site. Deadmen serve this function by providing the necessary weight and stability, allowing for safe working conditions during construction.

This application is particularly crucial in situations like deep excavations or when dealing with retaining walls, where the risk of soil movement can lead to significant safety hazards. Thus, the use of deadmen is essential for maintaining structural integrity and safety on a construction site.
