How to carry out a levelling traverse or run The Levelling Procedure · Construction Technology 1 Details of the Surveying practical 1 and 2, 17 Rise and Fall method, practical 1 The aim of this exercise is to produce a contoured drawing of your 'block of land' survey on the dayRise and fall method In this method, the difference of level between two consecutive points for each setting of the instrument, is obtained by comparing their staff readings The difference between their staff readings indicates a rise if the back staff reading is more than the fore sight and a fall if it is less than the fore sight

Rise and Fall Method;Rise and Fall method is a method of surveying to carrying Bench Mark from a known point to another unknown point In this method BS and FS reading are taken by fly levelling1st take the known point BS reading then take FS readingNow shift the instrument foreword and order 1st BS Staffman to go forewordNow take the take the BS reading which was FS reading of 1st settingRise and fall method Height of instrument method deals with obtaining the RL of the line of collimation by adding BS reading of a point whose RL is known The RL of line of collimation is called Height of Instrument From this, the staff readings of all intermediate stations is subtracted to get the RL at those points

What Is Height Of Instrument And Rise Fall Method Of Levelling

Levelling in surveying Designing Buildings Wiki Share your construction industry knowledge Levelling is a process of determining the height of one level relative to another It is used in surveying to establish the elevation of a point relative to a datum, or to establish a point at a given elevation relative to a datumExample of HI Method The following staff readings were observed successively with a level, the instrument is moved after fourth and sixth readings 225, 150, 095, 210, 290, 154, 075, 195, 210 m Enter the above readings in a page of a level book and calculate the RL of points by height of instrument method, if the first readings was taken with a staff held on a bench mark of 100 mIs basically BS FS to give a rise or a fall if its a rise add it to the reduced level If its a fall take it away (you should have been given a bench mark for a level for the starting point ie the reduced level starting point metres in this example)
