Ground Preparation <ul><li>It consits of adapting the ground for the construction through demolition, debris removal and nivelation. In this process is require de use of heavy machines for example excavator or devasting. </li></ul>
Foundations <ul><li>It consists of the construction of elements that form the base of the building. The materials used are the socle, that are individual platforms for each pillar, the flagstones, that are floating sheet that are support directly from the ground, and the pile, that are supports of big size that can be built in a open cavity of the ground. They are make of concrete. </li></ul>
Structure Elevation <ul><li>It is the stage in which pillars and foundations that form the “skeleton” of the building. This structures are made of reinforced concrte, mass concrete, steel beam and jack arch brick.The machine mainly sued are crane. </li></ul>
Covering <ul><li>It consist of the construction of the cover of the building. The materials used in the construction of cover are tiles, arabic or mixt, slate slab, metallic slab or fribrocment slab. </li></ul>
Building external coverage <ul><li>In this process exterior walls are built that isolate the interior from the enviroment. It is cover with polyurethane foam rubber. </li></ul>
Paving and Wall up <ul><li>It is the stage in which is built the floor and the partition, that divided the floor of the building. The materials used in the paving are stone ware, wood, marble, granite and terrazzo. The materials use for the partition are bricks and dry wall. </li></ul>
