Building the Mold: Crafting Concrete Formwork with Precision

In these images, a construction worker is preparing formwork—temporary molds used to hold wet concrete in place until it sets. The process involves aligning wooden planks and nailing them together along vertical reinforcing steel bars (rebar).
The worker first positions the board precisely, ensuring it lines up with the rebar spacing. Then, nails are driven in to secure the form firmly. Properly built formwork ensures that concrete structures (such as beams, columns, or foundations) maintain their shape, alignment, and strength during curing.
Attention to accuracy and stability in this step is crucial to avoid leaks or deformities when the concrete is poured. Skilled workers often reuse wooden boards, balancing cost-efficiency with safety and structural quality.
