What is the bottom cross section dimension for third- and fourth-order accuracy monument survey control management?

The bottom cross section dimension is the size of the reference base on the monument used for higher-accuracy surveys. For third- and fourth-order accuracy monument survey control management, the standard specifies a compact, square face of 35 cm on each side. This smaller dimension helps keep the mark stable, durable, and easy to re-locate in the field, while providing a clear, repeatable reference surface for precise measurements. Why not larger or in meters? A 40x40 cm size is larger and not the specified standard for these orders, and dimensions in meters would be impractically large for a field monument, making the mark cumbersome and harder to maintain.
