3 4 5 method of setting out a building- 12 RIGHT ANGLE TRINAGLE USED IN SETTING OUT One of the most important procedure used in setting out is the process of ensuring that all right angle corners are properly aligned One of the simplest ways is to use the method known as 345 triangle method Since the corner pegs of the building are to be removed during excavation these points are transferred outside that periphery by extending lines and driving pegs in the ground The following procedure applies to a simple layout as shown in Figure 44, page 44, and must be amended to apply to different or more complex layout problems
The 3 4 5 method is an application of the Pythagoras Theorem ie Forming right Angle Most times, 2 or 3 people are involve in this 3 meters is Measure from the Parallel Line created, then 4 Meter Away from the First point forming a Right Angle, you use your Measuring tape to Confirm the distance between the 3m point noted at the parallel line and the 4m noted at Process of setting out a Building 1Students will first identify the site plan which shows the building footprint Before the work begins, the students need to be able to identify that the architectural plans are stamped by the County Government for approval This is because if the drawings are not approved, it's the masons 🕑 Reading time 1 minuteSetting out of building foundation trenches is the process of laying down the excavation line and centerline on the ground based on the foundation plan The setting out process is also called as ground tracing that is performed before commencing the excavation process Once the design of foundation is complete, a
3,4,5 miles, or 3,4,5 centimeters, the right angle is still there So If we are looking at a house plan in the sketch above, I could use say 2M as my unit I would bang a nail in the formwork 8M (that is 4units of 2M each) from the bottom right hand corner Another one would go in at 6M (3units of 2M) along the other edgeBuilding & Construction Information 345 method is commonly used for setting out the right angle by using the tape which gives pretty accurate right angle and is widely used in day to day practice Person 1 holds the zero mark & 12m mark of tape Person 2 holds the 3 meter mark of the tape Person 3 holds the 8 meter mark of the tape When all the sides are stretched, a triangle
Setting out is done based on the principle of "Whole to part" According to this principle the largest possible rectangle of the building is found and set up first Then it is further divided into small parts completing the major setting out for the building It is very important that setting out process is done in a horizontal plane 36 x 36 = 1296 6724 1296 = 80 sqrt 80 = 5 Using the m along the house as a base line, the outside corners are set out by measuring 36m from one end of the base line and 5m from the other For an extension this is the best way of setting out Whenever I'm setting out I put all the diagonals on the drawings before handSecond stage setting out Second stage setting out continues on from the first stage, beginning at the ground floor slab, road subbase level etc Up to this point, all the control will be outside the main construction, for example, the pegs defining building corners, centre lines and so on will have been knocked out during the earthmoving work and only the original control will be undisturbed
