Construction Survey: Elements, Equipment, and techniques used in Construction Surveying

A construction survey established or marks the desired position of the building corners, roads, utilities, and sidewalks designed by an engineer. It receives prime attention to ensure the building does not overlap or encroach over the designated setbacks, property lines, or easement.

Different elements surveyed in a construction survey

1. The existing condition of a future work site
2. Stakeout limit of work, lot corners, and location of a construction trailer
3. Verifying location of structures during construction
4. Giving horizontal control on various floors
5. Stakeout markers and reference points that guide the development of new structures
6. Conducting an As-built survey, a survey that is held at the end of the project to verify whether work authorized is completed to the specification set on the plan.

Equipment and techniques used in construction surveying

Surveying equipment like theodolites and levels measure absolute angular deviation, vertical, horizontal, and slope distances. Along with computerization, electronic distance measurement, GPS surveying, Laser scanning, and total stations have supplemented the traditional optical instruments.



The equipment Builder’s level neither measures vertical nor horizontal angles. It combines a telescope and spirit level to allow the user to establish a visual line of sight along a flat plane. It can transfer elevations from one place to another when used together with a graduate staff. Another method to transfer height is by using water in a transparent hose, as the water level in the tube at opposite ends will be the same as elevation.

To Conclude

Mostly, the results of construction survey in Kelowna are observed in building, roadway, or other human-made improvements.
