Introduction to the stages of building from zero to one hundred – the last section

Construction process; vector molding and finishing
At this point, the jaws are placed beneath the molds to withstand the forces for a specified period of time. After executing the steel structure or molding in the concrete building, it is the staircase and the creation of pavilions. Wall and ceiling insulation should then be installed, including sound insulation and heat insulation. The insulation is usually done within a short period of time during the construction process, followed by various plumbing and installations.
After the piping is completed and the pipes are insulated, it is time to place the pottery and the main materials in the walls. Concrete is sprayed on walls where the finishing work is completed. This is usually done with special machines that push the concrete out. However, in some cases for small buildings this may be done manually. Bleaching is another process of building after concrete spraying and it can be said that the final work on the walls and ceiling is done at this stage. Finally, exterior design is based on previous designs and installation of accessories such as boilers, cabinets and more.

Some important points
It is necessary to explain that prior permission for the construction process must be obtained from the relevant institutions to begin construction. The building permit is one of the most important basic permits that must be obtained before construction begins; otherwise, the municipality will prevent any construction operations.
Another point to note is the comparison between the concrete structure and the steel structure; each has advantages and disadvantages. For example, the steel frame is less resistant to fire and heat, but on the other hand, the speed of the steel frame is much higher than that of the concrete structure and will speed up the construction process faster because the steel frame can be run simultaneously in all parts. Be. The cost of steel used in the steel structure is higher than that of steel in concrete construction; also, since mortgages on construction projects are paid on completion of the construction process, concrete buildings can be loaned after the completion of each floor. Received and financed the construction of the other floors.
However, in buildings constructed of steel, the relevant loans can only be obtained at the end of the entire construction. Steel structures have longer lifespan than concrete structures and also have decay value, meaning that when steel buildings are demolished, steel skeletons can be sold as second-hand, but concrete demolitions have nothing to do with them. . Considering the issues mentioned, one cannot absolutely choose between these two types of structures, but it must be determined depending on the type of building and its type of use.
