What is the Best Survey Type for Construction?

What Type of Survey Do I need for My Construction Work?

When it comes to construction, there are many factors that can affect the success of a project. To ensure safety and efficiency, owners need to be aware of the best survey type for their needs. There are four different types: aerial surveys, boundary surveys, topographic surveys, and 3D laser scanning. Each one has its own advantages and disadvantages.

Aerial Surveys: Aerial surveys are popular for fast and inexpensive solutions. They can cover large acreages of land quickly and efficiently but they do not have the same level of detail as other survey types.

Boundary Survey: Boundaries can be determined using a boundary survey which involves measuring distances between two points, usually at opposite corners or along property lines. However, this method is only appropriate in cases where maps are unavailable because it relies on accurate measurements that must be made by hand with tools such as strings, tapes, rulers and markers. This process also takes much more time than aerial surveying which has become increasingly common in recent years due to low costs and increased accuracy over previous methods like photogrammetry (taking photos from one spot and using a series of measurements to map out features in the photo).

Topographic Survey: Topographical surveys are most often used by engineering firms as they provide an accurate representation of ground elevations. This type is also appropriate for projects involving excavation or earthwork when builders need to know how much material needs to be removed from one area versus another. However, this type can take up more time than other types since it can involve calculations that require advanced math skills. It’s worth noting that this process should only be done by professionals with extensive experience because mistakes made during these calculations could have significant consequences on a project such as inaccurate design estimates which would increase cost overruns later on down the line.

Laser Scanning: The use of lasers for scanning has been utilized in surveying for over 20 years. It’s an accurate, cost-effective alternative to traditional survey methods like aerial and topographic surveys that are often used by civil engineering firms or construction companies.
