Contracting and carrying out contracting and work rights

The increasing awareness of the quality level of various structures and buildings and the rise of expectations regarding availability, safety, and ensuring the performance of various parts of the structure has led to the emergence of different disciplines in quality inspection.
Today, paying attention to the quality level of materials and components used in the structure and how to use them in execution is one of the most important and key points in all small and large projects.

Experience has shown that in order to successfully implement any project, the ability of the project contractor is the first word. Therefore, before starting any project, it is necessary to know what contracting is and the types of contracting contracts and their implementation methods.

The contractor is an inseparable part of various construction projects, oil, gas, etc.
A contractor is a natural or legal person who is responsible for the implementation of the contract based on the documents and according to the specified time, cost and quality.

Sometimes, contractors entrust the performance of a part of the operations under the contract to a natural or legal person who is specialized in carrying out executive works, which are called subcontractors.

A contracting agreement is a contract according to which the employer assigns the contractor to perform an action under certain conditions, against a certain amount and within a certain period of time.

Choosing the right type of contract to carry out projects can reduce project costs by an average of 5% and the duration of project implementation by 33%.

The types of contracting contracts are:

1) single agent or trust:

In this method, the employer himself prepares executive agents including manpower, machines, equipment and materials and undertakes the executive management of the project.

This method is often used in small projects that do not have wide dimensions. In this method, all 3 main phases of the project, i.e. engineering, procurement and implementation, are the responsibility of the employer. Since the employer himself does the work. The lack of motivation in the employer's executive personnel is one of the unfavorable factors in single-factor contracts.

Also, due to the lack of other executive elements such as consultants, contract managers, contractors, etc., in this method, compression is observed in all activities, which requires proper management of the employer. The lack of experienced professional engineers or the lack of equipment and The required machines cause delays in these projects.

Also, the lack of strong management in the work execution stages and the lack of proper coordination between manpower and equipment cause the project implementation process to be longer.

2) two factors:

In this method, the employer reduces his risk by placing the responsibility of all activities related to design, purchase of equipment, implementation, installation and commissioning on the responsibility of a contractor and puts the heavy responsibility of project management and implementation on the contractor.

The speed of work in two-factor contracts is high. Since the contractor is responsible for the design and engineering of the project, he is able to start the implementation phase of some activities once the design is finished. Of course, it is possible for the contractor to carry out the design. creates contradictions between some designs of the contractor and the employer.

Due to the fact that in this type of contract, the contractor performs design and implementation activities, the lack of transfer of technical knowledge from the contractor to the employer in this method causes the employer to be unable to use technical documentation and experience in similar cases.

3) three factors:

The most common method of contracting contracts is the three-factor method, which is also referred to as the contractual method or the conventional method. In this method, in addition to the two factors of the employer and the contractor, a third factor called the consultant is also added to the contractual factors. In this method, the employer considers a consultant as the one who performs all the design steps and entrusts the execution of the work to the contractor.

One of the disadvantages of this method is the differences in the attitude of the designer and the executor, that is, the consultant and the contractor. Also, modifying and revising the design during execution in this method is very time-consuming.

4) Four factors or implementation management:

In the four-factor method or management contract, which is a type of conventional three-factor system, the employer employs another external organization to manage the project.
The task of this institution is to manage and control the project and coordinate between planning and implementation.

The use of this institution reduces the responsibility and risk of the employer.
The management contracting method is one of the methods that are often used in large projects. This method was actually created to help the employer in solving the shortcomings and limitations of the three-factor method. The four-factor method can be considered as the newest method. Enumerated contractors' contracts.

5) Design, procurement and execution:

The design, procurement and execution method is also referred to as turnkey method.
In this contractual method, the contractor is responsible for design, procurement and execution, and the employer's risk is reduced because by transferring all project activities to the contractor, the employer is relieved of these responsibilities.

Most infrastructure and industrial projects in developed countries are implemented in this way.
But the disadvantages of this type of contract can be mentioned as follows
1) In case of design changes by the contractor, the quality will decrease significantly.
2) The contractor provides less services to maintain his profit.
