In quantity surveying it means extracting all the measured items in a drawing so as to create a "bill of materials". For example, if building a home you need to know the quantity of all the materials required, so you 'take off' and list all the lumber, drywall, piping, fittings, tiles, etc., etc.

What are the classification of surveying?
Surveying can be classified into two main categories: plane surveying and geodetic surveying. Plane surveying deals with small areas on the Earth's surface where the curvature of the Earth can be neglected. Geodetic surveying involves measuring large areas and taking into account the curvature of the Earth.
What is a term for collecting peoples opinions?
Survey, surveying, polling. Taking a poll.
Why was the ordinance of 1785?
Congress created a system for surveying - taking a detailed measurement of an area or land.
What is backsight in surveying terms?
In surveying, backsight refers to sighting a previously established point in order to orient the instrument before taking new measurements. This helps ensure accuracy and consistency in surveying work by referencing known points.
Who taught George Washington about the trade of surveying?
oh get off of this i am in a good mood
Why is levelling important in surveying?
Leveling in surveying is important to get an accurate measurement. The rise and fall of the grade will cause the measurements to be off, resulting in an inaccurate measurement of plots of land.
What is meant by transiting in theodolite surveying?
Transiting in theodolite surveying refers to the process of aligning the theodolite to a reference point by rotating it horizontally and vertically. This ensures that the theodolite is accurately positioned before taking measurements or readings. Transiting is essential for establishing precise horizontal and vertical angles in surveying work.
Types of surveying in civil engineering?
Plain Surveying Geodetical Surveying
What is the function of clamp screw in plane table surveying?
The clamp screw in plane table surveying is used to secure the alidade or sighting equipment in place on the plane table. It helps keep the equipment stable and prevents it from moving while taking measurements or making sightings. This ensures accuracy and precision in the surveying process.
What are the classes of surveying?
The main classes of surveying are geodetic surveying, topographic surveying, cadastral surveying, construction surveying, and hydrographic surveying. Geodetic surveying deals with large areas and high accuracy measurements for mapping the Earth's surface. Topographic surveying focuses on determining the natural and man-made features of a specific area. Cadastral surveying involves demarcating property boundaries. Construction surveying is done to guide the construction of infrastructure and buildings, while hydrographic surveying is used to map underwater features.
Different types of compass in the field of surveying?
prismatic surveying and surveying compass.
What are general classifications of surveying?
General classifications of surveying include geodetic surveying, plane surveying, topographic surveying, cadastral surveying, construction surveying, and hydrographic surveying. Geodetic surveying deals with large-scale measurements of the earth's surface, while plane surveying focuses on small-scale measurements on a flat surface. Topographic surveying involves mapping of the land's natural features, cadastral surveying deals with land parcel boundaries, construction surveying is used for building projects, and hydrographic surveying is for mapping bodies of water and their features.
