House Construction Steps - On site demonstration
The construction of house is commenced with the proper arrangement of a plan. Plan is prepared on the basis of floor plan, structural drawing of beam/column/foundation together with measurement of the rooms.
Prior to start the construction work, clear the site of rocks, garbage and trees for the house. Then, levels the site, arrange wooden forms to function as a template for the foundation and excavate the holes and trenches.
For laying out plan, center to center distance is chosen. Lay out is completed by placing ropes. Then the area is excavated based on the marking on the ground. Soil is dug from the marked position. The excavated portion should be cleansed properly. Now, the area is fully arranged to start base concrete work.
All the materials should be arranged properly on the day of starting the concreting work. The cement should arranged on the nearest day of concrete work. If there is no space of storing cement and it is stored in open area, the quality of cement get damaged.
The rock or gravel should be arranged well before the day of concrete. For the base concrete work, 4 mm or 1½ inch gravel should be used.

River sand or M sand should be stockpiled. In case of using M sand, it should washed properly.
A concrete mixer is set on the construction site. 1½ inch gravels are provided on the bowls and delivered to the mixture. M sand is also taken on the bowl and delivered to the mixture. Then cement is added. Water is added to the mixture from time to time as per water cement ratio. So, the materials of concrete is mixed consistently.
Prior to placing concrete, the excavated area should be sprinkled with water.
In one mix, one bag of cement; 5 bowls of M sand and 7 bowls of 1½ inch gravel are applied. After being mixed properly, the materials are delivered to the required excavated area. A mark is made to the excavation up to which the based concrete is provided. The mark is made through a steel rod or a piece of wood. After placing the concrete in the excavation, the mix is scattered with a spade manually up to the level. Then it is jammed properly.
Next structure of the foundation should be Reinforced Concrete Cement Structure. To get more details about reinforced concrete cement structure, go through the following video tutorial.
