What is a key reason to perform alignment checks on formwork during placement?

• A. To reduce curing time.
• B. To increase surface roughness.
• C. To shorten the pour duration.
• D. To ensure final geometry and prevent distortion.

Answer: (D)

The main idea here is maintaining the exact size, shape, and location of the formwork so the finished concrete matches the design. Formwork supports wet concrete as it flows and sets, and the pressure from the pour can cause forms to shift, bow, or tilt if they aren’t properly aligned and braced. By checking alignment during placement, you ensure the faces are square, level, and true to the drawings, and that joints and edges line up correctly. This keeps the final geometry from drifting and prevents distortion that would affect fit, openings, surface finish, and embedded components. It’s about preserving the intended dimensions and shape, not about curing time, surface roughness, or how long the pour takes.
