- Crayons, Chalk & Markers.
- Flags & Line.
- Nails & Markers.
- Identification Markers.
- Pipe Nails.
- Stakes & Pins.
- Station Markers.
What is the instrument used for setting out the angles of a building?
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.
How do you set out in building construction?
STEPS
- Site clearance.
- Obtain the architect or building plan.
- Get the necessary materials ready (i.e. pegs, nails, rope or line, hammer, tape, marking tool etc)
- Firstly, take note of the four corners where we have the proposed columns/pillars or as case might be.
What is the purpose of setting out a building?
Setting out a building is the process of transferring architectural proposals from drawings into the ground. It establishes the location points for site boundaries, foundations, columns, centre-lines of walls and other necessary structural parts. Also, it establishes the buiding’s correct extent, angle and level.
What are Markingout tools?
Marking-out tools
- Pencil – Used to mark lines and centres for cutting or joining.
- Try square – Used to help draw perpendicular lines on materials to mark out the sides of a woodwork joint.
- Marking gauge – Used to scribe lines parallel to edges so that waste wood can be chiselled away from a woodwork joint.
What is the 3 4 5 method of setting out a building?
4.1 Setting out Right Angles: the 3-4-5 Method The second person holds between thumb and finger the 3 metre mark of the tape and the third person holds the 8 metre mark. When all sides of the tape are stretched, a triangle with lengths of 3 m, 4 m and 5 m is formed (see Fig.
Who is responsible for setting out a building?
As a setting out engineer you will be responsible for getting a construction site ready for development. This can include working with detailed site plans and levelling the ground ready for work to begin.
What kind of tape do you use to set out a building?
For shorter distances, the steel tape is most appropriate, eg distances between two rooms, thickness of wall while setting out etc. For larger distances, eg perimeter wall measurement, hexagonal check, the flexible type is most appropriate.
Why are tape measures made in different sizes?
Tape measures are often designed for specific uses or trades. Tapes may have different scales, be made of different materials, and be of different lengths depending on the use it is intended for.
What is the procedure for setting out the tape?
The procedure is then to simply turn to the required bearing and measure the distance ensuring that the tape is held as near horizontal as possible We will look at the calculations for Points B1, B2, MH26 & MH27 from Control Point 2. The data shown in black in Table 1 was established when the control points were set up.
How to measure the distance back to the building?
Measure back towards the building a distance equal to half the wall thickness at each end of the extended line at fix a peg (one at each end) Assuming a 600mm bucket is to be used for excavation measure 500mm each side of the peg and fix in place the profile posts.
