- HI (Height of the Instrument) = 100 ft + 5 ft = 105 ft.
- Elevation of middle point = 105 ft – 6 ft = 99 ft.
- Elevation of new benchmark = 4.5 ft – 7.5 ft + 99 ft = 96 ft.

How is elevation measured in construction?
The building height is the vertical distance between finished grade and the highest point on the building, provided that the measured elevation does not include fill or berms. However, on sloped sites the building height is measured from the average finished grade to the highest point on the building.
What is BS and FS in survey?
From each levelling station, measure a backsight (BS) and a foresight (FS) , except: at starting point A, where you have only a backsight measurement. at ending point B, where you have only a foresight measurement.
What is FS in surveying?
The Fundamentals of Surveying (FS) exam is generally your first step in the process to becoming a professional licensed surveyor (P.S.). It is designed for recent graduates and students who are close to finishing an undergraduate surveying degree from an ABET accredited program.
What is the most accurate way to measure elevation?
The most important altitude measurement tool in your phone's arsenal is the GNSS/GPS receiver. If your phone can find at least four satellites, with one directly overhead, you can usually get an altitude reading accurate to within 10 to 20 meters (35 to 70 feet).
How to find the elevation difference between two points of land?
If you’re trying to find a difference in elevation between 2 points of land, use tie a length of string between two posts and use a level to determine the difference. Steps.
What does it mean if your elevation is positive?
If the number is positive, then your location is that many feet or meters above sea level. If your measurement is negative, then you’re that amount of feet/meters below sea level. Someone who lives near the mountains will be at a much higher elevation than someone who lives on the coast.
How to measure a metal post?
Measure the height of the posts with a measuring tape. Place the bottom of a measuring tape at the foot of the metal post. Start where the post enters the ground, and stretch the tape to reach the top of the post. Write down or memorize this measurement, as it will come in handy later.
How to find your exact location on Google Maps?

How to find benchmarks in a plot?
1. Try to find 2-3 benchmarks in the area. Look around the plot of land to search for benchmarks, or objects that have a consistent elevation. Since the elevation of certain objects (e.g., trees, bushes) can change over time, try to choose a sturdy, unmoving object as a benchmark.
How to find grade in degrees?
Using basic trigonometry, you can find grade in degrees quickly. The diagram below shows the three basic aspects you’ll need to find grade. Simply take “rise over run” and use arctangent (tan -1) to find theta (θ) – that’s your grade in degrees. Returning to our example, the rise is 2 and the run is 6.
How to use transit level?
Transit levels can be used to help you figure out the angle created by a set of three objects, and the distance between each object relative to the other two.
What is grade in construction?
Grade of an object’s physical feature, a landform or a line (plane) is used to indicate the slope of the thing being measured. Applications of grade include physical features like hills, riverbanks and canyons and construction aspects such as roads, roof pitch and landscaping. In other words, how to find elevation grade is an important skill in ...
What is elevation grade?
Elevation grade (or slope) is the steepness, or degree of inclination, of a certain area of land. It can simply be the steepness between two specific points in a given area, the average of an area's gradual change in steepness, or an erratic variation in the elevation of the ground. We usually measure the ground's elevation as its altitude ...
