What are methods of setting out?
The method of setting out is the reverse of surveying process. The process involves the positions and levels of building lines and road alignments shown on the construction plans to be established on the ground by various techniques and instruments.
What is the 3 4 5 method of setting out a building?
To get a perfectly square corner, you want to aim for a measurement ratio of 3:4:5. In other words, you want a three-foot length on your straight line, a four-foot length on your perpendicular line, and a five-foot length across. If all three measurements are correct, you’ll have a perfectly square corner.
What is builder square method of setting out?
The Builders Square is used where walls meet, calculating rafter angles, creating stairways, calculating octagons, and can be used as a diagonal square. The SAVAGE™ Builders Square’s precision laser etching makes this square the most accurate in the industry.
What is the difference between surveying and setting out?
Abstract. A definition often used for setting out is that it is the reverse of surveying. What is meant by this is that whereas surveying is the process of producing a plan or map of a particular area, setting out begins with the plan and ends with some particular engineering project correctly positioned in the area.
What are some common examples of materials involved in setting out a building?
By far, brick is the most commonly used building material, followed by cement, timber, roof tiles and gypsum plasterboard.
What is the 3 4 5 Triangle rule?
The 3:4:5 triangle is the best way I know to determine with absolutely certainty that an angle is 90 degrees. This rule says that if one side of a triangle measures 3 and the adjacent side measures 4, then the diagonal between those two points must measure 5 in order for it to be a right triangle.
What is theodolite method of setting out?
A theodolite or total station is set up over a control point which has known co-ordinates. The instrument is then pointed at another control point in order to orientate the instrument to north. If a conventional theodolite is being used it normal to turn the instrument to north and reset the horizontal angle to zero.
What are the types of construction methods?
The procedures and techniques utilized during construction. These include preparation of the project site, earthmoving, foundation treatment, steel erection, concrete placement, asphalt paving, and electrical and mechanical installations.
What is setting out PDF?
The International Organisation for Standardisation (ISO) define setting out as: Setting out is the establishment of the marks and lines to define the position and level of the elements for the construction work so that works may proceed with reference to them.
What is setting out as used in building construction?
What is setting out? Also known as “staking out” or “laying out”, setting out in surveying is the practice of transferring the building design onto the land itself so that the workers can follow it during construction. Key points and guide markers are set out to ensure accurate building takes place.

What is the purpose of setting out in construction?
Setting out procedure is done in order to clearly define the outline of the excavation and the centre line of the walls so that construction can be carried out exactly according to the plan. The centre line method of setting out is generally preferred and adopted.
