What is the purpose of tell tales used by form watchers?

• A. To measure concrete volume
• B. To check form elevation and plumb
• C. To ensure safe worksite conditions
• D. To prevent air infiltration

Answer: (B)

Tell tales, used by form watchers, are specifically employed to monitor the elevation and plumbness of formwork in construction. Their primary purpose is to provide visual indicators that help ensure the forms are correctly aligned during concrete placement. This is critical because any deviation in elevation or plumb can lead to issues in the structural integrity and finishing of the concrete work. When tell tales are installed, they typically consist of a string or other indicator that reflects the vertical and horizontal alignment of the forms. As concrete is poured, workers can observe these tell tales in real time to ensure that the formwork remains stable and within the intended specifications. Maintaining proper form elevation and plumb is essential for achieving the desired aesthetic and functional outcomes in the finished construction. In contrast, the other options focus on different aspects of construction monitoring and safety that do not directly relate to the specific function of tell tales.
