The foundation is a construction that determines the structure of a building. The foundation serves as the support burden that was on it and determine the strength of a building. Understanding more clearly by

Definition Foundation
The foundation is a very important element of the building, as a part of the construction of the building that serves as the foundation of the buildings on it. and according Sonny Yoedono Benedictus (Sonny Yoedono Benedictus blogspot) And ensure solid footing to put buildings and building expenses continue to be distributed from top to bottom soil structure foundation strong enough. The foundation therefore should not experience any change in position or move, in the sense of moving horizontally or upright. The strength and robustness of the construction of the building depends on the foundation construction. To plan a foundation must meet the following requirements:
The construction should be strong and sturdy to support the building above it.
The material used for the construction of the foundation must be durable and not easily destroyed, so hopefully when the damage occurred not because the foundation is not strong.
The foundation must be located on the basis of hard ground, so that the position of the foundation is not easy to move either sideways, or rolled down.
Characteristics Foundation
To select the type of foundation that needs to be considered is whether the foundation is suitable for a variety of conditions in the field and whether the foundation is allowed to be settled in accordance with the schedule of work economically?
Here are the things to consider in selecting the type of foundation:
The state of foundation soil
Time and cost of work

Sturdy, rigid and strong.
In general, the basic foundation soils have different characteristics, different parameters affecting soil characteristics such as the influence of groundwater that would result in severe soil volume submerged in contrast to the ground is not waterlogged soils same though. The type of soil physical and mechanical characteristics of each give strong support different land. Thu. A foundation must be well planned, because if the foundation is not properly planned will be part of a larger decline than the surrounding areas (Cornellia Rimba).
There are three criteria that must be met in the design of a foundation, namely:
The foundation must be placed precisely, so it does not collapse due to outside influences.
Pondasi should be safe from kelongsoran carrying capacity.
The foundation must be safe from excessive decline.
Types of foundation
A. Shallow Foundations
Shallow foundations are usually made near the soil surface, the depth of the foundation established generally less 1/3 of the width of the foundation to a depth of less from 3 m. Shallow depth of the foundation is not the standard rules, but it is a guideline. Basically, the surface loading or other surface conditions will affect the bearing capacity of shallow foundation. Shallow foundation is usually used when the soil surface is quite strong and rigid to support the loads imposed where it supports the type of structure is not too heavy and not too high, shallow foundations are generally not suitable in a weak or compressible soil is very poor, such as soil density urug poor, shallow foundations are also not suitable for the type of peat soil, subsoil young alluvial deposits and soil types, etc..

B. Foundations In
The foundation is a foundation established in the ground with a certain into which the basic foundation bearing capacity is influenced by structural loads and ground conditions, the foundation is usually installed at a depth of more than 3 m below ground surface elevation. The foundation can be found in the form of a pile foundation, walls or foundation piles and caissons compensation. The foundation can be used to transfer the load to deeper layers to achieve certain to get into the soil that supports the building so that the load power strutur unsuitable soils near the surface of the ground can be avoided (Hendra triyatmoko). Types of foundation:
Pile foundation
Foundation Piers (diaphragm walls
Foundations Caissons (Drill Pile)
CONCLUSION
Based on the explanation above, it can be concluded that the determin the construction in the foundation is the strength of a building. Characteristics of the foundation that must meet the standards of the state of the land and its location. While other types of shallow foundation and the foundation of which the foundation.
