Which class of formwork is used for temporary or light loads?

• A. Class I
• B. Class II
• C. Class III
• D. Class IV

Answer: (D)

Formwork class tells you how much load the forms are built to carry and how long they’ll be reused. For temporary or light loads, you want the simplest, lightest formwork that can still safely support the fresh concrete until it reaches strength. Class IV is designed for these situations, using lighter materials and simpler framing, making it easier to set up and strip and more cost-effective for short-term or light-duty pours. The heavier classes are meant for higher loads and longer reuse, so they’d be unnecessary and more costly for temporary or light-load applications.
