Why is it important to accurately model the land features of your project site with a toposurface?
It's important to model the land features in order to create an easy-going process between the designer and those that are in charge of creating the structure. If you design a home with incorrect land features, it will cause many problems, as the design can’t be built since the instructions aren’t clear. Things ranging from the foundation, to the latitude and longitude of where the structure will sit, will not be communicated properly and therefore when built, there will be many mistakes, or the whole design will have to be updated. It’s extremely important also when there are land fixtures such as trees or other environment components that could interfere with the construction of the design.
When designing a project...
When designing a project a combination of both would work since changing a whole terrain could affect the environment as well as be really extensive labor. You can always make the design to reflect the components of the terrain and from there decide whether changing the terrain is cost friendly or modifying the design to fit the terrain is better. While excavating is really popular in terms of building the home, it also is very extensive and therefore it's difficult to decide which way is the best when designing.
Why do stairs follow specific proportions with a set relationship between the tread length and riser height?
Stairs follow specific proportions when talking about tread length and and riser height. These proportions are set in place in order to follow a common standard in terms of people stepping up and down stairs safely. You don't want really high risers that make you fall, or very short treads that don’t support your whole foot when going down and up the stairs. It’s all put into place in order to avoid accidents and allow the general population to be able to safely go up and down the stairs. Building modeling is helpful since it displays how the stairs look and if they are functional property since they are being designed. This allows for them to be correctly built once the design is correct and is functional.
