What is the dimension of standard concrete monuments defining the position of provincial, city, and municipal boundaries?

In surveying, boundary markers need to be reliable, durable references that can be found and reoccupied years later. The standard concrete monument used to mark provincial, city, and municipal boundaries is a square cross-section pillar with a 30 cm by 30 cm base and a height of 100 cm. This size strikes a practical balance: it’s thick enough to resist ground movement and weather, and tall enough to be easily seen above ground cover and to accommodate any official engravings or seals. Smaller cross-sections, like 15x15 cm, would be less stable and more prone to damage or displacement, making re-surveying harder. Larger cross-sections, such as 40x40 cm or 50x50 cm, would add unnecessary weight and cost without giving notable benefits in stability or visibility. So the 30 x 30 x 100 cm dimension is the standard that provides durability, visibility, and practicality for long-term boundary marking.
