To set out right angles in the field, a measuring tape, two ranging poles, pegs and three persons are required. The first person holds together, between thumb and finger, the zero mark and the 12 metre mark of the tape. The second person holds between thumb and finger the 3 metre mark of the tape and the third person holds the 8 metre mark.

Wherever a feature intercepts the tape, write down the measurement. With a second tape, take offsets at 90° to the first tape, measuring across to trees or other features in the garden.

Surveying, a means of making relatively large-scale, accurate measurements of Earth’s surfaces. It includes the determination of the measurement data, the reduction and interpretation of the data to usable form, and the establishment of relative position and size according to given measurement requirements. Jul 20, 2018 · Offset in Chain Survey. Suppose AB is a chain line and p is the corner of a building. Two points ‘a’ and ‘b’ are taken on the chain line. The necessary requirements for field work are chain, tape, ranging rod, arrows and sometime cross staff. It is a system of surveying in which sides of various triangles are measured directly in the field and NO angular measurements are taken.

Sometimes numbers on a stake designate an "offset" of so many feet to the point of survey For example, a stake could be marked "C/L OS 15ft", which means the stake is offset from the center line by 15ft. The surveyor's field book is the only place you will find all the right answers, or later on the prints. Best of luck

SURVEY 1 PRACTICAL REPORT ON LINEAR MEASUREMENT AND LEVELLING In surveying, tape correction(s) refer(s) to correcting measurements for the effect of slope angle, expansion or contraction due to temperature, and the tape's sag, which varies with the applied tension. Surveyor swings the tape on chain line and selects the point on the chain where offset distance is the least (Fig. 12.13) and notes chain reading as well as offset reading in a field book on a neat sketch of the object.

The first step for both methods is to set out a tape measure through the centre of the area to be recorded, this is called a baseline Tape Baseline A tape measure laid between two Control Points . Distances are measured from this baseline to features on the site using another tape measure or a measuring rod. Chain Surveying Project Description of the Project… The intersection method depends on the measurement of two angles.

Construction surveying techniques are also used for verifying the location and quantities of completed work (as-built). Traditionally a "station/offset" method was used for establishing construction control. The introduction of computers, total stations and GPS in surveying have revolutionized the way construction surveys are done now.

offset is 10 feet beyond the catch and for cut sections the offset is 7 feet beyond the catch. When using a rod, level, and tape, the conversion from elevations to rod readings will A steel tape is sometimes equipped with a reel on which the tape can be wound. A tape can be, and often is, detached from the reel, however, for more convenient use in taping. Various types of surveying tapes are shown in figure 11-36. View A shows a metallic tape; view B, a steel tape on an open reel; view C, a steel tape or To set out right angles in the field, a measuring tape, two ranging poles, pegs and three persons are required.

The second person holds between thumb and finger the 3 metre mark of the tape and the third person holds the 8 metre mark.

But for comparatively short lengths to be measured, a tape of 30 meter long and 6 mm wide will be probably found as a more convenient size. Types of Measuring Tape Used in Survey.

Surveying, a means of making relatively large-scale, accurate measurements of Earth’s surfaces. It includes the determination of the measurement data, the reduction and interpretation of the data to usable form, and the establishment of relative position and size according to given measurement requirements. All offsets which are not at right angles to the main survey lines are known as oblique or tie line offsets such as CD and CE (Fig. 3.4.) When the object to be plotted is at a long distance apart from the chain line or it is an important one such as a corner of a building, oblique offsets are taken.
