Before undertaking any project, it is important to make sure that proper surveying is done. Surveying helps you make a clear plan of action regarding how to proceed with your project, and ensure its success. Engineering surveys deal with every aspect of an engineering design like the topography of the area, layout of the building, etc. Professional engineering surveys tend to be much more detailed than those done by civil engineers, and serve additional purposes as well.
The main purpose of an engineering survey is to find out more about a site either before or after the construction is done. It can be used by architects, builders and civil engineers to prepare base plans. Engineering surveys are essential for all large scale construction projects such as railway lines, roads, dams, bridges and planned residential areas. Civil engineers in particular rely heavily on them to make sure that the plans are perfect.
These surveys can be divided into various categories depending on their purpose. Typically, they fall into three main categories: design, planning and construction. Planning surveys are done before the construction work starts at a particular site. They include channel alignment surveys and investigation surveys which include channel cross section, valley, gully, vertical control and reservoir area surveys. These forms of surveying help engineers get a complete picture of the situation of the site. After the planning is done, design surveys are done to check the feasibility of the project, and make changes if necessary.
Construction surveys are an important part of surveying and project management and they can be done both during and after the completion of the work. They serve to keep a check over the entire construction process to make sure that all relevant standards are met. They can also be used for the maintenance of the buildings, once the construction is done. Some examples of this type of surveying include emergency spillway, principal spillway, existing channel and embankment surveys.
Surveying can be done using various methods. One of the newest and most effective ways of conducting engineering surveys is using a technique called lidar surveying. This technique uses 3D scanners to provide accurate measurements of both the interior and exterior of buildings. However, this method can only be used after the construction is done. Professional surveyors use theodolites, Dopplers, total stations and GPS devices to make sure that their task is executed properly.
The area in which surveying is done would dictate the tools used by the surveyors. Differential leveling uses a mounted telescope and a tripod to measure lengths and angles. Trigonometric leveling uses various mathematical equations to help with the surveying. Surveying is a complicated process and is done by a team of specialists including planning engineers, field engineers and hydrologists.
As you can see, proper surveying is an essential part of project management. If you need engineering surveys done, make sure that you hire the services of a trained and reputed professional. Bear in mind that only surveys done by certified and licensed surveyors are considered good enough.
