Surveying is a task that is crucial to many industries, and while you might not have ever given the subject much thought, your safety each and every day depends upon the skills of trained surveyors. Here are some reasons why surveying is an extremely important job.
We have all seen a person standing in the street looking at the road through a special device known as a theodolite. This is a common surveying instrument that measures angles in both the horizontal plane and the vertical plane. This instrument, as well as clinometers, digital levels, GPS receivers and total stations are just some of the tools that surveyors must learn to use.
Each tool helps a surveyor take highly accurate measurements, which are needed for many projects, not the least of which is road construction. Not only does a surveyor monitor the creation of roads, they also help build railways and even bridges. In addition, they are called in after construction to keep an eye on the complete project as it ages over time. Failure to make note of structural problems can result in huge catastrophes, such as when a bridge collapses. During initial construction, roads are graded and sloped according to safety standards, and surveyors are the ones who ensure that these roads can accommodate different levels of traffic and different types of vehicles.
In the past, surveyors were used to establish boundary lines, and this is still a very important job. When new communities are developed or new houses are built, surveyors need to come in and set the boundary lines. Surveyors also are called in when there is a dispute regarding boundaries.
Creating boundaries is often one of the initial tasks at a new construction site, but surveyors also painstakingly monitor the progress of every step of construction. They begin by making sure that the ground is level and that the foundation has been constructed properly. If the ground is not level or the foundation is not level, this can result in many serious problems. Surveying engineers also are called in to inspect older buildings to look for any serious or even minor structural issues.
Aside from the buildings of roads and structures, surveyors also are engaged in mapmaking or cartography. This includes highly detailed maps of landforms and waterways. This is needed by many groups, from commercial shipping operations to geologists to those searching for natural resources. In fact, surveyors are often employed by mining companies to help set up new mines or improve and expand operations at existing mines.
