Surveying is the back bone of construction projects, we must need surveying before starting a construction project, during execution of construction activities and after completion of project.

Before starting project surveying help us in design and calculation of quantities.

During execution of construction activities surveying is most important thing, It help us to maintain the exact locations and heights.

After completion of project surveying is called topographic surveying and it helps us to prepare the As-Built drawings, to make comparison between design and actual constructed structures, to check the differences.
