BASIC SETTING OUT IN CONSTRUCTION

“Setting out” is the process of locating points for columns, site boundary level, pile position and other necessary structural parts according to the construction drawing. Errors should be avoided because the whole structure will be build based on the respective setting out. A setting out should be made to full fill the requirements such as length, angle and level.

Steps for the simple setting out for a building

A temporary bench mark or level should be obtained to start the setting out for the whole building.

A specific height from a near land or from the road level can be obtained as the reference level point for a setting out. This level point will conduct all over the building boundary area or 1m away from the building boundary level.

Reason – The excavation work should be done as shown in the engineering drawing.

From this point, can continue the setting out related to the given drawing.

Take angular setting out – Right angles setting out to mark the next columns on a straight line. (Use the Pythagoras theorem)

Finally, after the completion of setting out for the whole building, use a twine to connect the centre lines of all columns. (Use the bench mark reference height to connect all of them).
