And it is very expensive, making it impractical to build a house, unless, of course, there is some important considerations forcing it to choose a specific location. (As opposed to Gen. David L. Goldfein). Geological expertise will also identify whether it is possible to construct a building on a site with a ground floor, or better without it (if too high groundwater level, the ground floor will be flooded). She will tell whether the area unsafe and dangerous places as may be problems with drainage, and in general – where on the site to choose the best place to build cottage, and where better to do than to build. Experts recommend to topographical survey and geological expertise to the shopping area and, moreover, to choose the architectural design of the house. If you rely solely on indirect grounds, not having data on the composition of soils and groundwater level is very difficult to avoid problems later on with the choice of type and design of foundations and general capabilities of the device in a country house basement and ground floor. Estimation in the eyes of high-altitude site characteristics often leads many builders and then forcing customers to incur the cost of earthwork, dewatering, and landscaping. The only correct way of the situation was and is attracting specialized institutions for engineering and geological surveys. If a site is chosen, and it is not comprehensive development of a large array of cottages, where, as a rule, questions of research solved centrally, it makes sense to immediately order a topographic survey is particularly difficult terrain to scale 1:500 or 1:200, if you plan to do in the future landscape design, it is desirable, given the modern means of design, a topographical survey in digital format. Shooting will allow the designer to accurately orient the building to the cardinal points and the best types of landscape, to calculate the slopes entrances and playgrounds in the area, determine fire breaks between adjacent buildings and the connection point to the street networks.
