Final answer:
The 'grade level' is the term for the ground level where the foundation of a building will meet, which is a critical starting point in construction. A level horizon ensures floors and ceilings are horizontal, affecting both the building's stability and aesthetic. Proper grade setting is foundational in the step-by-step construction process, from the lowest to the highest level.
Step-by-step explanation:
The term that refers to the level of the ground where it will meet the foundation of the completed building is known as the 'grade level' or simply 'grade'. In construction, establishing the correct grade is crucial for setting the foundation of a building. The grade level is the reference point from which builders measure the elevation of the foundation and the subsequent floors of a structure. The building process itself generally starts from the lowest level and works its way up to the highest level in a systematic manner, ensuring that all floors and ceilings are horizontal and align with the level horizon, a concept which is fundamental for both aesthetic and structural reasons.
Understanding how to ensure a level horizon is vital in construction projects, as this affects the stability and appearance of the building. Floors and ceilings should be parallel to the horizon to create visually pleasing and structurally sound buildings. Additionally, the spacing and proportions within the building, often following mathematical formulas, rely on this initial leveling.
