Differential leveling survey methods/equipment to achieve second-order standards are: • Compensator-type (automatic) engineer’s level (three-wire observations) with a one piece invar-tape yard rod. Three-wire leveling involves reading and recording all three of the horizontal cross-hairs for each shot. The object of this levelling operation is to obtain a record of the undulations of the ground surface along the centre line of a proposed engineering project such as a road, railway or canal etc. distance on horizontal axis and height on vertical axis). In profile levelling, you find the elevations of points placed at short measured intervals along a known line, such as the centre-line of a water supply canal or the lengthwise axis of a valley. You find elevations for cross-sectionswith a similar kind of survey (see Section 8.2). Prepare a set of profile leveling notes for the raw leveling data listed below and show the arithmetic check. Profile leveling is also defined as a surveying method carried out along a central line of a piece of land on which linear engineering work is to be conducted. in land surveying maps and plan showing the features on the land. Fly Levelling Procedure. In this chapter we will discuss the terms, equipment, and procedures for two types of leveling. lab #5: chain surveying (mapping by tape) 15 lab #6: study of level and levelling staff 18 lab #7: differential or fly levelling – reduce levels by h.i method 22 lab # 8: differential or fly levelling – reduce levels by rise and fall method 24 lab # 9: closed loop leveling 26 lab # 10: profile leveling The usual procedure is to determine the profile. Leveling is an art of determining the relative height of different points on, above or below the surface. A stake is set at TP2, and a foresight of 5.35 ft is observed. The reduced level of the benchmark is used to determine the reduced levels of other points. Differential and profile leveling are two surveying methods that are very useful for agricultural and horticultural projects. For planning and estimating project works like roads, bridges, railways, airports, water supply and waste water disposal surveying is required. What is the stationing of the turning point if it is instead located 83.45 m before the given reference point?

All data in feet. STADIA LEVELING. Levelling report-1. Introduction(Refer next slide) Leveling is the general term applied to any of the various processes by which elevations of points or differences in elevation are determined. Land Leveling. Elevations are needed to set slope stakes, grade stakes, footings, anchor bolts, slabs, decks, sidewalks, curbs, etc. Now attach two tapes to the nail on the top of the peg (or survey arrow). This allows the surveyor to immediately verify whether the readings are correct. Principles of levelling : a) Simple levelling : The operation of levelling for determining the difference in elevation, if not too great between two points visible from single position of the level is known as simple levelling. Differential and profile leveling rank next to the measurement of distance in importance as a surveying technique. Spirit leveling is a precise way to obtain data for smaller land areas, and is commonly used along road, railroad tracks, aqueducts, and canals. Experienced pacers can measure distances within 1/50 to 1/100 in open and level terrain. • Electronic digital/bar-code leveling system with one-piece invar rod. INSTRUCTIONS -Profile leveling is a method of surveying that has been carried out along the central li ne of a. tract of land on which a linear engineering work is to be constructed/ laid. 4.

Business Profile. Surveying hand calculations: 1. In surveying, a PROFILE is a vertical section of the earth measured along a predetermined or fixed line. Profile leveling is an extension of differential leveling, and a closure check is required if the line runs between bench marks. It has a compensator which consists of an arrangement of three prisms. The elevation of BM A is 1,213.65. Since the chosen area has irregularities in steepness, setting of ground points was indeed hard. From this cross section of the alignment is drawn. Procedure for profile levelling 1.Longitudinal levelling. ROAD SURVEYING Section I. RECONNAISSANCE SURVEY ... graphic map or profile and cross-section leveling. You will use a non-sighting level, such as the flexible tube water level (see Section 5.3). Leveling, one of several procedures of surveying, is the process of determining the elevation of points such as the ground, the tops of stakes, or parts of a building. One report per student is required for the first lab. The following chapter will discuss the … The instrument is moved, and a backsight of 4.00 ft is observed on station 460. Harrelson et al. Civil Engineering questions and answers. Ordinary Differential Leveling Determining or establishing elevations is, at times, the most essential activity of the field engineer. In this case, readings of intermediate stations are taken and reduced level of each station is found. Many different types of surveys can be used depending on the desired results. The level may be moved to a temporary point called a turning point (TP) The elevation of a point is the height of the instrument (HI) minus the foresight (FS) Differential Leveling TopHat Problems CIVL 1101 Surveying - Introduction to Differential Leveling 5/7 In Profile Leveling usually, the surveyor assigns an elevation of 100.00 units to the datum rather than considering the “Mean Sea Level” as the datum. Leveling is the process of determining the elevation of points on, above or below the surface of the earth. (1994) also provide a nice graphic example of proper field book notation for level surveys. The data generated by a profile survey can be used to determine the slope between points, depths of trenches, ground clearance for overhead power lines, and many other applications. Two staves are useful for this. Longitudinal profile levelling by traversing : 11. Surveying: The value of curvature and refraction corrections. The right Leica equipment and accessories calibrated from an approved laboratory at a specific time can give you a good quality measurement. Profile leveling is a method of surveying that has been carried out along the central line of a track of land on which a linear engineering work is to be constructed/ laid. The basic concept of leveling involves the measurement of vertical distance relative to a horizontal line of sight. It is a branch of surveying which deals with the measurement of the elevation of the point with respect to the datum level above or below the surface of the ground..
