Which statement correctly describes Initial Dead Load?

Which statement correctly describes Initial Dead Load?

• A. It refers to loads after deck curing
• B. It refers to loads before the concrete deck is hardened
• C. It refers to wind and seismic loads
• D. It refers to live loads from occupants

Answer: (B)

Initial Dead Load is the weight the structure must carry during construction, specifically while the concrete deck is still fresh and has not yet hardened. This phase includes the weight of the forms, reinforcement, and the freshly poured deck as it sits before curing, along with any temporary bracing needed to support the structure. That’s why it’s described as loads before the concrete deck is hardened. Once the deck cures, its weight becomes part of the permanent dead load, not the initial condition. Wind, seismic, and live loads are separate categories: wind and seismic are external dynamic forces, and live loads come from occupants or vehicles, not the fixed weight of materials during construction.
