For example, in most of the cases, you will have to build pillars if you have an infill site. Therefore, it is better to evaluate the quality of the soil before purchasing it, or before deciding to build a construction.

Before digging a foundation , you have to prepare the site thoroughly. Consequently, you have to remove the trees and most importantly their roots. Nevertheless, you have to comply with the local regulation regarding these issues, otherwise you risk a significant fine. If on your site there are a lot of old trees, it would be a good decision to search for another land, as it is very expensive and time-consuming to cut trees, transport them and remove their roots from the ground.

In order to dig the foundation , you have two main options: renting a hydraulic digger, or hire several people to dig the trenches by using shovels. Obviously, the first alternative will do the job quickly, but there are cases in which a hydraulic digger might not have access to narrow or isolated sites. In that case, the only solution is to hire persons to dig the foundation by using shovels. From our experience, digging a foundation with shovels is better and cheaper than renting a digger.
