Types of Land Surveying

Posted on: 24 September 2020


A land survey is a science that involves measuring both natural and human-made features by applying the principles of geometry and mathematics. A land surveyor uses various tools to measure things like the elevation, boundaries and angles on a property. There are different types of land surveying, each with its purpose. Here's a look at the main types of land surveying in the country.

Cadastral Surveys

A cadastral survey is one of the most common land surveys in the county. It's used to establish the boundaries of your property. This type of survey helps landowners determine what area they're working with.

A cadastral survey involves field and record research. This includes making measurements and computations to set boundary lines based on state laws. It also entails locating encroachments and easement lines.

Construction Surveys

A construction survey involves staking out structures on a piece of property. This includes walls, roads, buildings and utilities. The process of staking gives construction workers important details for implementing improvements highlighted on development plans.

Construction surveys can be further classified depending on the project in question. For example, for excavation, a special kind of construction survey called a bulk earthwork survey would be conducted. Construction surveying also sets out grid marks, footings, columns, penetrations, and foot slabs.

Topographic Surveys

Topographic surveys are meant to define any human-made and natural features in a specific area. The surveys identify existing trees, hedges, creeks and regions with sloping land. The findings of topographic surveys help engineers and architects work around natural obstructions.

Topographic surveys also identify human-made structures, including barriers, buildings, fences or any landscaping elements. Engineers need to consider these structures when making development plans. This type of survey is mainly implemented by using a combination of ground field methods and aerial photography.

Subdivision Survey

A subdivision survey is necessary when dividing a piece of land into small tracts, estates or lots. This survey is essential during the design of drainages and streets. The survey has to be recorded by the state and local government agency.

Subdivision surveys are mainly used when dividing a large piece of land into small units. These units are allotted for commercial and residential use. In the case of residential areas, these units are given to individuals in a family. Subdivision surveys also help property developers create an ideal sub-division plan.

There are many types of land surveys in the country, all of which vary depending on the purpose of the survey. Whether you're planning a development project or want to subdivide your land to different members of your family, it's important to familiarise yourself with the appropriate land survey regulations. Make sure you research and consult widely before choosing a land surveyor for your property.
