You should know that the topographical surveys can be quite essential to any kind of project, regardless of the size. The use of the latest in surveying technology, the topographical land survey may uncover a lot of unforeseen issues which save the developer some money and time.
The topographical survey would give an accurate representation of the ground’s surface and this will also allow the natural and manmade objects which include any existing structures, the boundary details as well as grid levels, the tree positions, ground surfaces and drainage. The topographical surveys 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 actually relates to such standard datum point in which the height and location are being determined already. In order to add more details to the topographical survey, the techniques like the 3D laser scanning or aerial photography may also be utilized. All of the information which are gathered onsite may be edited and supplied to you in whichever manner would suit you best in the 2D drawings or the electronic files.
Getting that topo survey on the project can highlight those possible issues. The distances between the surrounding properties are being recorded accurately in order to prevent potential boundary and 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. Because of climate change and the recent amount of heavy rainfall which led to several areas being flooded, the need for such topographical surveys has really increased. Due to such combination of the increasing rainfall which is putting pressure on the river banks as well as the manmade drainages and growing population, topographical surveys have certainly become a quite important tool for builders and developers.
The type and amount of such topographical survey detail which is collected on the site must be based on your specification. However, such experienced land surveyors can make use of their knowledge of planning to provide more information that could be important for any future design or 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.
