🧐 Frequently Asked Questions

Q. What is the purpose of a construction blackboard?

A. These blackboards are used in construction and civil engineering to embed crucial information directly into site photographs. They typically display the project name, type of work, location (station point), and contractor, providing clear, unalterable context for progress reports, quality control, and official records.

Q. Can I change the font or the layout of the table?

A. This tool uses a standardized, fixed layout and font to ensure clarity and professional consistency, which is a common requirement for official documentation. Customization of the table structure or font style is not currently supported.

📚 Fun Fact: The Role of the "Kokuban" in Site Photos

The practice of including an information board in site photos is a standard in the Japanese construction industry, where it's known as "shashin kanri" (写真管理, or photo management). This "kokuban" (黒板, blackboard) serves as a verifiable, in-frame record of the work being documented.

This method is highly valued because it prevents data manipulation and simplifies the daunting task of organizing thousands of photos from a large-scale project. By having the metadata visually present in the image itself, it ensures that each photo is self-contained and easily identifiable. While digital cameras and apps have modernized the process, the core principle of embedding key project data directly into the photograph remains a fundamental practice for reliable site documentation in Japan and beyond.
