Surveying or land surveying is the technique, profession, art and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them. A land surveying professional is called a land surveyor. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as building corners or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. Surveyors work with elements ofgeometry,trigonometry,regression analysis, physics, engineering, metrology, programming languages, and the law. We use equipment, such as total stations, robotic total stations, theodolites, GNSS receivers, retroreflectors, 3D scanners, radios, clinometer, hand held tablets, digital levels, subsurface locators, drones, GIS, and surveying software.

Scope

Consultants will perform engineering and related services for projects on an as needed, Task Order basis. Consultants will be required to execute a Task Order which will specify the scope of services, task schedule, and compensation. The specific services consist of the following:

Boundary demarcation survey Field based survey using modern surveying instruments has helped us in demarcating boundary and establishing pillars as and where necessary. Need based land demarcation projects was taken up for Government and Private Bodies.Based on the requirements temporary bench marking was done and later pillars were established.Science and Technology Park made use of modern survey equipment like Differential Global Positioning System (DGPS), Electronic Total Station (ETS).

Column centerline coordinate marking Center Line is a line that passes through the center of a column. Grid of similar lines for a number of columns form a centre line plan. Centre line plans helps you understand the exact positioning of a column on site.Column may be of different dimensions and but may have same center line. Centre line grid for columns are plotted on a land before beginning excavations. Checking for center line of a column grid ensures that columns are located at exact locations as per drawings.Total Station Surveys are conducted to plot the center line marking over the plot.

Land plotting works Plotting means to represent on paper, to a suitable scale, the previously surveyed objects in accordance with their shape and size. Plotting is commenced after the field-work is over. The plotting of a chain survey is done in the following steps: ... The scale depends upon the importance of the work and extent of survey.

Grid based level sheets To determine the positions of the contours on a plan the leveling methods are used to find the relative positions of points on the surface of the ground with reference to certain benchmarks at regular intervals. This technique of making observations and plotting on a plan is called as grid leveling.
