Intro to Antique Surveying Instruments

There are three kinds of surveying instruments that are rather unique to North American surveying. They are the compass, the chain and the transit. In addition, the engineer's or surveyor's level contributed very strongly to making the United States the leading industrial nation in the world by virtue of the highly efficient railroad systems it helped design in the mid 1800's. I take a great deal of satisfaction in pointing out that in this country it was the compass and chain that won the

Dumpy Level Survey–What, Where, How, Parts - Civil Engineering

The dumpy level is an optical surveying leveling instrument consisting a telescope tube firmly secured in two collars fixed by adjusting screws to the stage by the vertical spindle. The telescope of dumpy level can rotate only in a horizontal plane. Relative elevation of different points of a surveying land is determined with dumpy level.


Pegs (see Fig. 8) are used when certain points on the field require more permanent marking. Pegs are generally made of wood; sometimes pieces of tree-branches, properly sharpened, are good enough. The size of the pegs (40 to 60 cm) depends on the type of survey work they are used for and the type of soil they have to be driven in.

The levelling instruments essentially consist of the following: A levelling head with three foot screws which enables to bring the bubble at its centre. Telescope that provides line of sight to bisect distinct objects. A bubble tube to make the line of sight horizontal either mounted on top or side of the telescope.

Land Surveying Equipment, Surveying Supplies, Surveyor

The main pieces of surveying equipment in use around the world are the following: theodolite, measuring tape, total station, 3D scanners, GPS/GNSS, level and rod. Most survey instruments screw onto a tripod when in use. Analog or digital tape measures are often used for measurement of smaller distances. What is the most common survey equipment?

Chapter 10 Differential Leveling Survey Specifications › publications › manualsAll differential leveling equipment must be properly maintained and regularly checked for accuracy. Systematic errors due to poorly maintained equipment must be eliminated to ensure valid survey adjustments. Equipment acquisition, repair, adjustment, and maintenance are covered in Chapter 3, “Survey Equipment.”

Land Survey or Surveying Equipment: Used & New Construction

In the early 1900s, surveyors started to use surveying equipment such as planimeters, theodolites, automatic levels and measuring wheels. A planimeter is the best known tool for measuring asymmetrical land areas as they eliminate the need for charts or manual calculations; whereas a theodolite allows measuring of horizontal and vertical angles.

Surveying instruments - Designing Buildings Wiki

Surveying is the process and technique of determining distances and angles between points, used on construction sites for the purposes of levelling and setting out works . Surveying relies for its accuracy and efficiency on having the right instruments. Surveyors use a range of instruments for land surveying and mapping, and setting out .

SURVEYING USING A LEVEL INSTRUMENT › academics › aalfraihatSmall, “localized” survey work can easily and quickly be done using a level instrument. Potential weir sites, locations where road crossings, division boxes, etc. have to be built, can be mapped by taking a few cross sections in the field and working it out in the office.
