Analysis of EPC general contracting mode of 1
The basic connotation of 1. 1 In the process of long-distance pipeline engineering construction, EPC general contracting mode is the basis to ensure the smooth development of pipeline engineering construction. According to the operation requirements of EPC general contracting mode, EPC general contracting mode requires the general contractor to complete the overall design, procurement, construction and trial operation of the project according to the requirements of the project contract, ensure the orderly development and close integration of each stage, and reasonably control the safety, quality, progress and cost of the project. As the most widely used project general contracting mode at present, EPC general contracting mode occupies a large proportion in the contract volume of long-distance pipeline projects, which makes great breakthroughs and developments in China's long-distance pipeline projects.
Main features of 1.2. Compared with the traditional long-distance pipeline project construction management, EPC general contracting mode has many characteristics. Its application in practical engineering has brought greater benefits to builders and contractors. At the same time, it also bears a very important management responsibility, which provides a more reasonable management model for long-distance pipeline projects. EPC general contracting mode involves a large scale of engineering projects and is often used in the construction of large-scale long-distance pipeline projects. The whole project has a long construction period, which involves many interests and needs reasonable distribution. In addition, the construction cost of long-distance pipeline project is fixed, so it is necessary to transfer the project construction risk reasonably through EPC general contracting mode.
Application of 2EPC general contracting mode in long-distance pipeline project
2. 1 structural features.
2. 1. 1 large line length. Long-distance pipeline project needs to span multiple areas, which has the characteristics of high strength, strong fluidity and lack of support. These characteristics lead to heavy workload, long pipeline lines and many areas in the field construction of long-distance pipeline projects. However, there are some differences in the understanding of pipeline construction in different regions. In the process of project construction, the corresponding land acquisition and the relationship between workers and peasants may affect the implementation of long-distance pipeline projects.
2. 1.2 Information transmission is difficult and coordination organization is complex. In traditional engineering projects, managers, constructors and technicians will gather in a certain area for on-site construction. Through timely and effective communication, the smooth operation of the on-site management system can be ensured. However, in the long-distance pipeline project, the pipeline is often hundreds of kilometers long, and the hydrogeological conditions vary from place to place, and some areas even need to completely change the plan. The traditional management mode has been unable to cope with this situation. Moreover, many long-distance pipeline projects belong to concealed projects, and their on-site process management is very important. If it cannot be effectively controlled, the consequences will be very serious. Therefore, all contractors of long-distance pipeline projects must keep information unblocked, command well-founded and cooperation effective, and EPC general contracting mode can fully meet such requirements.
2. 1.3 distribution is difficult and the transportation distance is long. The long-distance pipeline project has a long construction distance, and the required pipes are large in quantity and volume. At the same time, a large number of equipment, facilities and other auxiliary materials need to be equipped in the field construction process, and these materials, equipment, personnel and machines need to be reasonably distributed to the corresponding sites. There are some problems in the distribution process, such as super-long and super-wide, and the transportation distance is long, so it needs multiple transportation to meet the construction requirements of long-distance pipeline engineering [2].
2.2 Responsibility of all parties. In the process of long-distance pipeline project management, EPC general contracting mode requires the owner to sign corresponding contracts with the supervisor and general contractor, and then the general contractor signs contracts with subcontractors. In the project management process of EPC general contracting mode, all parties need to clarify their respective responsibilities. The owner needs the general contractor to arrange the on-site project implementation, and the supervisor is responsible for supervising the project construction. The general contractor and the supervisor are fully responsible for the owner. In this management mode, the general contractor manages all subcontractors on site according to the contract, and the subcontractors are responsible to the general contractor. The specific responsibilities of each party are as follows.
2.2. 1 owner. The owner's management in the long-distance pipeline project runs through the whole construction process. The owner needs to carry out site selection, survey, planning and design in the preparatory stage of long-distance pipeline project, and select EPC general contractor that meets the construction requirements. In this process, it is necessary to ensure that the long-distance pipeline project is approved and the decision is correct, the relevant design scheme is scientific and complete, be responsible for the changes in each implementation stage, organize in-depth research on the planning and feasibility of the project, organize the basic design of the project, select the EPC general contractor through the preparation of the corresponding bidding documents, purchase the materials needed for the project, and provide the contractor with environmental conditions that meet the requirements according to the contract requirements. During the on-site project construction, supervise and manage the contractor's work activities accordingly, and finally organize relevant personnel and institutions to carry out inspection and acceptance to confirm the project construction and final completion status.
General contractor. The general contractor in the long-distance pipeline project needs to be responsible for the design, procurement, construction and other work in the project implementation stage. In the process of site construction, the cost, time limit, quality and safety of the project construction should be reasonably controlled to ensure that the project construction meets the requirements of corresponding environmental protection standards. In addition, the general contractor shall organize professional and technical personnel to provide corresponding support for the design and procurement of long-distance pipeline projects, and ensure that the quality and construction period of the whole long-distance pipeline project meet the corresponding requirements by coordinating the relations between all parties.
2.2.3 Supervisor. The main responsibility of the supervisor in the long-distance pipeline project is to effectively manage and supervise the long-distance pipeline project on behalf of the owner. During the on-site work, the supervisor should not only assist the owner to do the preparatory work, prepare all kinds of bidding documents and construction plans, but also effectively control the implementation process of long-distance pipeline project. The corresponding completion acceptance work should ensure the realization of the project construction quality and time limit for a project from an objective point of view, and timely check the project quality and time limit for a project on behalf of the owner.
2.3 Specific measures.
2.3. 1 Improve the project management system. The traditional management mode adopted in the construction of long-distance pipeline project can no longer meet the needs of current industry and social development. While contacting a large number of excellent construction cases, the owner is gradually changing the project management concept of long-distance pipeline projects. In the process of project implementation, it is necessary to fully clarify the site management procedures, clarify the responsibilities of all parties and individuals, set scientific and reasonable management scope and boundaries, establish and improve the long-distance pipeline project management system, and ensure clear responsibilities and strong execution.
2.3.2 Implement effective contract management. In the concrete construction process of long-distance pipeline project, the signed project contract is the basic basis to ensure the smooth development of the whole project. The rules and regulations formulated by the owner, supervisor and general contractor in the process of project implementation and the corresponding guidelines to be followed in the process of contract management need to be clear. All parties must follow the basic principles of honesty and dynamic management, work in strict accordance with the provisions of the contract during the site construction, reduce site design changes and temporary contract modifications, and take effective management measures for violations of the contract.
3 Conclusion
In the process of social and economic development, the demand for energy is increasing, and its transportation engineering is becoming more and more important. The application of EPC general contracting mode in long-distance pipeline engineering can fully clarify the main responsibilities among owners, supervisors and general contractors. Implementing EPC general contracting mode in different ways is an important foundation of China's long-distance pipeline construction industry. With the development of China's economy and the improvement of project management level, EPC general contracting mode will continue to innovate, and gradually form an EPC general contracting mode with China characteristics, laying a solid foundation for energy engineering construction in China.
