How to do construction work:

Description:
The main methods of building the facility are shown in the following figures. These methods are as follows:
1- Employer construction workforce (work done by the employer himself)
2- Construction work management by the employer
A) Hiring the members of the organization to do the work (trust)
B) Performing work by subcontractors
Note: One of the two methods (a) or (b) or both can be used

3- Doing construction work by a general contractor.
4- Construction work contract from design to execution or design-construction contract (rejection key).
5- Professional construction work management
Many large industrial organizations, and a number of government departments, have their own construction workforce. These forces are primarily used for repairs, maintenance, and replacement work. But such workers usually also have the authority to hire new construction projects. Employers often use their construction staff to manage their new construction work. The employer acts as a general contractor and signs subcontracts with a specialized contractor.
Construction work by a general contractor with a master contract is probably the most common way to build a facility.

Here we just mention that the use of two new methods in providing construction services is increasing:
A) Design method – construction (or turnkey).
B) The method of applying professional management in construction affairs.
The concept of design-construction or turnkey construction work is that the employer enters into a contract with an institution, according to which the contracting institution undertakes both the design and construction of facilities that meet specific needs (usually in terms of implementation). Meet. Often companies accept such contracts that specialize in a particular type of building and also have standard designs that are tailored to the client’s wishes.

Because both design and construction work is done by an organization, coordination problems are minimized and construction work can begin before the final design is completed. (In conventional construction methods, it is also possible for construction work to begin before the design is completed. In this case, the construction contract will be based on payment. This construction method is called the “fast track” method.) These disadvantages The main method of design – making it difficult to create competition between suppliers and the complexity of evaluating their proposals.
The use of professional construction management to build facilities is also somewhat different from the conventional construction method. In this case, the building manager acts as the employer’s representative and manages both the design and construction of the facility. The employer enters into three separate contracts for the design, construction and construction management of the project. Adopting this method in construction work will save time and money due to the close coordination between design work and construction work. Opponents of this approach, however, point out that construction work management assumes little or no financial responsibility for the project, and that the cost of the service it provides does not result in any savings from improved coordination in the design work. And renders construction work fruitless.

Designer, calculator and contractor of the building:

In the building ID card, there is a section related to the work experience of the following people:
A) Construction designer (ie architectural engineer)
B) Accounting Engineer
C) Builders and workshop organizers who include:
The contractor, engineer, workshop supervisor, technician, architect and in general the people in charge of the technical departments in a limited number or those who have been effective in the construction of the building from the beginning of work or parts of the implementation of the company. In this section, the work address (companies) and their telephone numbers are registered. In case of any problems, the above-mentioned people, who are fully acquainted with the construction of the building, will be helped to make major repairs in accordance with the existing plans. In general, the building identification card is very useful during breakdowns and repairs. And with its help and guidance, repairs are done in a short time and at a low cost.
Construction site:
Studies that should be done before starting work on the location of the building, issues such as weather effects, rainfall, changes in ambient temperature, especially in cold and frosty seasons, have adverse and destructive effects on materials, components and parts.
It is noteworthy that, in each re-launch and up to the workshop in many ways, there are many problems, including technical issues, collecting the desired director, especially at a higher cost, which firstly: delays the delivery of the building; Second: it increases the cost of the building.
Before starting a small or large building plan, the ground resistance under the direction of the walls should be determined for the designer so that they can create the location of the columns, walls and the plan as a whole, usually good ground, dark green with soil grains. They have a high density and adhesion.
Different types of soil are sandy, clayey, dodge, rocky or mixed.
Most of the lands in Iran are of clay types. These soils are hardy and if there is fine-grained and coarse-grained sand in them. It will be reliable. In some cases, the building is built on sloping clay soils, in this case, the principles of stability of the building should be considered so that there is no risk of drift when the ground moves.
Dej lands also have complete, dense and reliable compositions on which high-rise buildings can be built.
In general, the earth has different layers and compositions, each layer of which should be tested. In ordinary buildings, we can be aware of the type of earth by drilling wells and leaving soil layers, but for the construction of high-rise buildings, we can speculate. Sounding should be done from different layers of foundation and construction of the building.
In some cases, the land is sandy or loamy. In this case, the foundation advances to the level of hard ground and is constructed with basic foundations and, if necessary, flat foundations.
In short, recognizing the soil for the designer’s performance and calculations is one of the basic and very important issues for building a building that neglecting it will cause many problems and damages.
