Topography refers to the measurements involved in the contours and elevations of land. This is particularly useful when it comes to excavating an area for building. It is useful when designing a building to completely understand the contours of the earth on a construction site. A topography map can help a contractor or excavator to get an idea of the lay of the land. This will allow them to see how the land runs and the different elevations. The professionals can predict how the water might run from the area and decide how to level areas for the construction of buildings.
A construction professional might need the help of topography to create a site plan to develop a new building or even an entire subdivision of housing. They might need this information to ensure that they are building structures in locations that will be most beneficial if there is a flood. They might also need them if they are trying to determine where they want to put the buildings. A professional may work in conjunction with the architectural engineer, site designer and excavator to come with the best plan for the buildings using the topography of the area. They could also use the information to predict the movement of the earth around an area. This is very helpful in areas that are susceptible to earthquakes. The slope and topography of an area is vital to knowing how flooding plays into a building project and whether a plan is needed to avoid flooding.
