For anyone planning on new construction of any type of building or other structure, you know that surveys are needed before the work ever begins. Land surveyors are different than construction surveyors, however, and it's good to understand this difference and what these surveyors can do for you before you start work. Note too that they can ensure that the construction work has been done properly, after it's finished. Note a few reasons why you need to call a construction surveyor before you plan any type of construction, even a residential home, and why you might call them after the work is completed.
Boundaries Versus Guides
One unique difference between land and construction surveyors is that a land surveyor notes the boundaries of land as well as its topographical information, whereas a construction surveyor can help to guide construction work along a tract of land. As an example, if you're looking to construct a very large apartment complex, a land surveyor can tell you the boundaries of the plot you've purchased and note if there are encroachments, but a construction surveyor can tell you how to build each building around water features, trees, and the like. They can also assist in noting the best way to direct plumbing pipes and other underground features so they're out of the way of tree roots and other hazards.
Adding to Construction
Another reason to work with a construction surveyor in particular is that adding to construction can be affected by the land itself. For instance, if you want to put an additional story on your home, this will put added weight on the foundation and the soil. If you want to expand that apartment complex parking lot, adding concrete to an area close to a water feature can mean soil that is too soft to support it. A construction surveyor can work with you to ensure these types of things are planned properly before construction begins. A land surveyor can usually only tell you if your addition to current construction will create encroachment on another person's property, or if you will need an easement, not if it can be supported.
When Work is Finished
Another aspect of construction surveying versus land surveying is that a construction surveyor can note if work is done in terms of length and other such dimensions. For example, they can note if that new parking lot for your apartment complex is as large as promised, or if bridges, roadways, and other such features are as long as intended, things that a land surveyor does not usually check. For any construction project, it's good to call such surveyors from a place like Transit Technical Services after work is done to ensure it's been done right.
