What is staking out in surveying?
Construction surveying or building surveying (otherwise known as “staking”, “stake-out”, “lay-out”, “setting-out” or “BS”) is to stake out reference points and markers that will guide the construction of new structures such as roads or buildings.
What is the distance between the stakes in laying out a building?
In most cases you want to make sure your batter boards have enough room for you to move your lines while you try to square the building. So, place your stakes at least 4 feet apart from each other and use batter boards that are at least 5 feet long.

What are the basics of surveying?
Surveying is the process of measuring the relative positions of objects near the earth’s surface. It involves making distance and angular measurements. Surveyors use these measurements to calculate the position of objects in three-dimensional space relative to a known point.
What is horizontal and vertical angle?
A horizontal angle is the difference between two measured directions. Horizontal angles are measured on a plane perpendicular to the vertical axis (plumb line). Vertical angular measurements are measured to determine slope of survey lines from the horizontal plane (level line).
How do surveyors measure distance?
To measure distances, land surveyors once used 100-foot long metal tapes that are graduated in hundredths of a foot. To measure the horizontal distance between two points, one surveyor uses an EDM instrument to shoot an energy wave toward a reflector held by the second surveyor.
What is a backsight in surveying?
1 surveying : a reading of the leveling rod in its unchanged position when the leveling instrument has been taken to a new position. 2 surveying : a sight directed backward to a previous station.
How do you calculate backsight?
Measure a backsight on A (for example, BS = 1.89 m). Measure on C a foresight FS = 0.72 m. Calculate HI = BS + E(A) = 1.89 m + 100 m = 101.89 m. Find the elevation of turning point C as E(C ) = HI-FS = 101.89 m – 0.72 m = 101.17 m.
How do you calculate RL in surveying?
9. 8 Rise and Fall Method This method consists in finding the difference of level between consecutive points by comparing each point after the first with that immediately preceding it. The reduced level (R.L.) is found by adding rise of subtracting fall to or from the preceding reduced level itself (R.L.).
