You must know that those topographical surveys can be very important to any type of project, whatever is the size. Using the latest in the surveying technology, a topographical land survey may uncover various unforeseen issues which would save the developer some money and also time.
A topographical survey could give an accurate representation of the surface of the ground and such will also permit natural and also manmade objects that include the existing structures, the boundary details, the tree positions, grid levels, the drainage and ground surfaces. The topographical survey may show an area in as much detail you need which would depend on the project size as well as the terrain that is involved.
Understand that information is normally gathered through the use of the electronic theodolite or total station that would measure the distances and the angles between those points on the ground. This relates to the standard datum point wherein the height and location are determined already. To be able to add more details to the survey, then those techniques like 3D laser scanning or aerial photography may be utilized too. All the information that are gathered onsite can be edited and also supplied to you in whichever you would fit you best in the 2D drawings or electronic files.
Having such topographical survey done on the project may surely highlight the possible issues. The distances between those surrounding properties are actually recorded accurately to avoid the potential boundary as well as right to light problems. The survey may also determine if you will be building on the flood plain or if the ground is actually at risk for flooding. Due to climate change as well as the recent amount of heavy rainfall leading to various places getting flooded, the need for those topographical surveys has surely increased. Due to the combination of the ever increasing rainfall that puts pressure on river banks, those manmade drainages and growing population, topo survey have surely become a very important tool for the builders and developers.
The kind and amount of topographical survey detail that is collected on the site should be based on your specification. But, the experienced land surveyors will make use of their knowledge of planning to offer additional information which might be essential for any future design or planning application. The information may be collected as well from utility companies that can be added to the topographical survey plans.
Aside from having that topographical land survey by the engineers, you may also save time for the project's designer and also reduced the risk for contractor through accurately mapping the drainage positions, the water supply as well as the electricity cables.
