Several models of engineering project management

Compatible with this, the management model of construction projects is also continuously developing. At present, there are seven project management models.
I, DBB mode
, that is, design-bid-bid-block mode, which is the most traditional engineering project management model. The management model is the most common internationally. The World Bank loan projects and the projects based on the International Consultation Engineer Federation (FIDIC) contract conditions are based on this model. The most prominent feature is that the implementation of engineering projects must be carried out in the order of design-bidding-construction, and only one stage can begin after the end of the end. my country’s first use of the World Bank loan project-
The Lubu Guan Hydropower Station project implements this model.
The advantage of this mode is strong generalality. You can freely choose consulting, design, and supervisors. All parties are familiar with the use of standard contract texts, which is conducive to contract management, risk management and reduction of investment. The disadvantage is that the engineering project must be transferred to the owner after planning, design, and construction. The project cycle is long; the owner’s management costs are high, and the early investment is large; it is easy to cause more claims when changing.
. The CM mode is construction-management (
–
) mode, also known as the staged packing method, is to hire construction experience from the beginning of the construction of the fast path method for construction. The CM unit participated in the implementation of the construction project in order to provide designers with suggestions for construction and subsequently responsible for the management of the construction process. This model has changed the traditional model of bidding after the design was completed in the past. The unit is responsible for the supervision, coordination and management of the project, meet with the contractor regularly during the construction stage, supervise the cost, quality and progress, and predict and monitor the changes in costs and progress. The CM model originally originated in the United States in the 1960s. Since the 1980s, it has been widely popular abroad. Its biggest advantage is that it can shorten the project from planning, design to completion, save construction investment, reduce investment risks. It can be relatively early Ground gain.
. DBM mode
is the design-construction mode (
design-build method
). Construction and design -construction contractors are not only responsible for the cost of design stages, but also can choose subcontractors or use the company’s professionals to complete the project by themselves, including design and construction. The only entity is responsible for the design and construction of the project, the design -the construction contractor is not only responsible for the cost of the design stage, but also to select the subcontractor or use the company’s professionals to complete the project by the company, including design and construction, including design and construction Essence In this way, the owner first chose a professional consulting agency to replace the owner to study and formulate the basic requirements of the proposed project. He authorized a person with sufficient professional knowledge and management ability as the owner’s representative to contact the design — construction contractor.
4. BOT mode
is to build-operation-transfer (
build-operate-transfer
) mode. The BOT model is a financing and construction method of financing and construction of government infrastructure construction projects that rises abroad in the 1980s to rely on private capital, or the privateization of state -owned projects of infrastructure. The government opens its own infrastructure construction and operating markets, authorized project companies to be responsible for raising and organizing construction, and after completion, it is responsible for operating and repaying loans. After the agreement expires, it will be transferred to the government for free. The BOT method does not increase the burden of foreign debt in the host country, and it can also solve the problem of lack of infrastructure and insufficient construction funds. The initiator of the project must have a strong economic strength (large consortium), and the pre -examination and bidding procedures must be complicated.
5. PMC mode
is the project contract (
Project
) mode, which is the owner hired a professional project management company to represent the owner’s organizational implementation of the project or several stages of the organization and implementation of the project. Management and service. Because PMC contractors have different degrees of participation and scope of their duties in the design, procurement, construction, and commissioning of the project, the PMC model has greater flexibility. In general, there are three basic application modes of PMC: 1. Owners choose design units, construction contractors, suppliers, and sign design contracts, construction contracts and supply contracts with them, and entrust PMC contractors to carry out engineering management. 2. The owner signs a project management contract with the PMC contractor. The owner selects the design unit, the construction contractor, the supplier (or part of it) by specified or bidding, but does not sign the contract. Contracts, construction contracts and supply contracts. 3. The owner signed a project management contract with the PMC contractor, and the PMC contractor selected the construction contractor and the supplier and signed a construction contract and a supply contract, but it was not responsible for the design work.
. EPC mode
is the design-procurement-construction (
–
) mode, which is also known as the “general contracting” model in my country. In the EPC model, not only the specific design work, but also the overall planning of the entire construction project content and the planning and specific work of the entire construction project’s implementation of the organization and management. In the EPC mode, the owner can roughly explain the investment intention and requirements, and the rest of the work will be completed by the EPC contracting unit; the owner does not hire supervision engineers to manage the project. Most risks such as natural force risks and unpredictable difficulties; the general price contract is generally adopted. In traditional contracting models, materials and engineering equipment are usually purchased by the general contracting unit of the project, but owners can retain the risks of the procurement of some important engineering equipment and special materials in the project implementation process. In the EPC standard contract conditions, the contractor is responsible for all design and assumes the entire responsibility of the project. Therefore, the owner cannot interfere with the work of the contractor too much. The basic starting point of the EPC contract conditions is that the owner has few participation in engineering management. Because the contractor has undertaken most of the risks of engineering construction, the owner focuses on completion acceptance.
Seven. The mode is the partnership () mode. It is a management model that determines the common goals of the construction project on the basis of fully considering the interests of all parties. It generally requires owners to reach a short -term or long -term agreement on the basis of mutual trust and resource sharing. By establishing a working group to cooperate with each other, timely communicate to avoid disputes and litigation, and jointly solve the implementation process of construction projects together The problems in the middle sharing the risk and related costs of the project to ensure the realization of the goals and interests of all parties. The partnership agreement is not just an agreement between the owner and the construction unit, but the construction project needs to be signed by all parties, including the owner, the general contractor, the subcontractor, the design unit, the consulting unit, the main material and equipment supply units, etc. Essence The partnership agreement is generally based on the three major goals of the construction project and the issues of engineering change management, disputes and claim management, safety management, information communication and management, and public relations. It’s really fast, it’s already in the blink of an eye

I don’t know where you are copied, and don’t think about the difference.
The project management model is a compassion. First of all, it is necessary to distinguish from whose project management: owners, design, construction, equipment units. From the perspective of the owner, the project management is divided into several categories. They are all about financing, implementation, and organizational models.
The first category, the financing model is about where the money comes from, asset rights and business transfer. TOT mode
4, ABS mode
5, PPP mode
6, PFI mode
Category 2, the implementation mode is about how to send out the construction task, there are several categories:
1, traditional mode (that is, parallel pack)
2, engineering project management mode
(1) PMC mode
(2) PM mode
(3) CM mode
3. Engineering general contracting mode
(1) “Traffic Key” mode (and EPC is not a mode)
(2) EPC mode
(3) DB mode
(4 4 ) Other engineering general contracting mode
The third category, organizational mode. It is about the organizational model of the owner’s management project. There are several categories:
1. The self -operated system of the construction unit
2, the three parties of the A, B, and C, and the engineering headquarters
4, the Infrastructure Office Room system
5, professional institution system
6, project legal person responsibility system
7, agency construction
, finally, the problem of chaotic management model category. The third category is the content of China. Most of the first and second categories have been moved by foreign management models. Foreign economic systems are different from the domestic economic system and legal foundation. It is easy to be chaotic. It should be classified first to clarify which aspect of it.
