Construction project management model?

What are the specifics of the construction project management model, the following Zhongda Consulting for you to answer.

1 Overview of engineering project management modes 1.1 Currently commonly used engineering project management modes ① traditional project management mode, that is, the design - bidding - construction mode (DBB); ② design - procurement - construction mode, that is, EPC; ③ construction management mode, that is, CM, according to the actual situation can be divided into agency-type CM and risk-type CM; ④ design - management mode, that is, DM, which can also be It can also be divided into two specific forms; ⑤ Project Management Contracting Mode, i.e. PMC; ⑥ Project Management Mode, i.e. PM; ⑦ Build-Operate-Transfer Mode, i.e. BOT.1.2 Connotation of Engineering Project Management Mode 1.2.1 Overview of Engineering Project Management Engineering project management is a systematic management activity of effectively planning, organizing, controlling, and coordinating the whole process of construction of engineering projects according to the objective economic law. From the content point of view, it is the management of the whole process of engineering project construction, that is, from the project proposal, feasibility study design, engineering design, engineering construction to the completion of the whole process of management, the construction of any project needs this process, it is phased, is the objective requirements of project construction. From the nature of the project management is the micro-foundation of fixed asset investment management, the nature of the investment management category. Engineering project management can be divided into project management of the constructor, project management of the contractor, project management of the consultant and so on according to the different management subjects, and this paper only discusses the project management of the constructor.1.2.2 Connotation of Engineering Project Management ModeEngineering Project Management Mode, refers to the object to be managed as a system, and through a certain way of organization and management, it enables the system to operate normally and ensures that its objectives are Realization. China's engineering project management mode should be selected in line with the laws of China's market economy and international practice, and can promote the development of capital construction. All parties involved in engineering projects have their own project management mode, but it is mainly the owner's project management mode that affects the progress and benefits of engineering projects. Therefore, the engineering project management mode discussed in this paper is from the standpoint of the owner's side, and the management of the project is carried out by an independently existing engineering project management consulting company (i.e., the third party of the project). Engineering project management mode is directly related to whether the project construction goals can be achieved, and whether the operation of the project after completion can achieve the established social and economic benefits. Therefore, it is of great significance to understand and select the appropriate engineering project management mode.2 Discussion on the Classification of Engineering Project Management Modes2.1 The Role of Classification of Engineering Project Management ModesAt present, there are a lot of engineering project management modes adopted in the actual domestic projects, moreover, with the gradual opening up of China's construction market, the process of engineering construction is also becoming more and more standardized, more and more engineering project management consulting firms are being set up domestically, and the owners also recognize the importance of standardizing engineering project management. However, many domestic construction participants, for the types and characteristics of engineering project management mode is still not enough to understand thoroughly. Therefore, it is necessary to classify the engineering project management modes often used in China, which is reflected in the following: ① synthesize and classify the commonly used engineering project management modes, which will help the construction parties, especially the owners, to understand and correctly select the engineering project management modes; ② classify the engineering project management modes used in China's actual projects, which will help to find out the gaps between China and the developed countries in the management of the projects, so as to learn and introduce the advanced project management modes. 2.2 The principle of engineering project management mode classification according to the project management company services are management or contracting nature, engineering project management company whether directly with the construction contractors to sign a contract and the size of the responsibility of the management company, the author of the engineering project management company project management mode is divided into two categories: the first type of mode (project management services) and the second type of mode (project management services) and the second type of mode (project management services). 2.2.1 The first type of mode---providing project management services Project management services refer to the engineering project management company's preparation of feasibility study report, feasibility analysis and project planning for the owner at the decision-making stage of the engineering project in accordance with the contract. In the implementation stage of the project, it provides the owner with services such as bidding agent, design management, procurement management, construction management and commissioning (completion and acceptance), and manages and controls the project on behalf of the owner in terms of quality, safety, progress, cost, contract and information. Engineering project management enterprises generally assume the corresponding management responsibilities in accordance with the contract. According to the scope of services provided, it can be summarized into the following types: ① management of certain objectives or work of the project; ② management of a certain (or certain) stage of the project construction; ③ management of the project construction by stages and objectives; ④ all-round and whole-process management of the project.2.2.2 The Second Type of Mode - -Providing project contracting services Project contracting here refers to management contracting, i.e., the engineering project management company contracts out the project in accordance with the contract, but the project management company is often only responsible for the whole process management of the project and subcontracts out the construction, design and so on. The project management contracting company should generally bear the corresponding management risks and economic responsibilities in accordance with the contractual agreement.2.2.3 Basic difference between the two types of modesProviding the first type of modes, the project management company acts as the owner's consultant and agent to provide the owner with the whole process or a certain stage of services. The responsibility of the project management company is to be responsible for coordinating the relationship between design and construction and between different contractors, and to manage the progress, cost and quality of the project in accordance with the entrustment contract, but the project manager is not responsible in this respect. The project management company providing the second type of model is usually evolved from the general contractor in the past, the project manager also plays the role of the general contractor of the construction at the same time, the progress of the project, the cost of the quality of the project are assuming greater risk. Provide the first type of mode of management company only with the owner to sign a contract, not with the contractor to sign a contract, no direct contractual relationship with the contractor, the contractor's binding force is small, directly involved in the development of project objectives parameters, it is the management of the project belongs to the nature of the service; the second type of mode is not only with the owner to sign a contract, but also with the contractor to sign a contract, the contractor binding force is large, it is contracted to the engineering project goals and parameters and to ensure their realization, it is the project objectives and parameters of the project. The second type of model not only signs a contract with the owner, but also signs a contract with the contractor, which is binding on the contractor, and it contracts for the project's target parameters and ensures their realization, and its management of the project is contractual. Therefore, the benefits of engaging in the second type of model are greater than those of engaging in the first type of model, but the risks are also greater. The difficulty of the second type of mode lies in how to reasonably determine the responsibility and authority and management interface between the owner and the project management company in terms of project financing and risk management, and how to reasonably determine the service income of the management company.2.3 Classification of Engineering Project Management ModesFor the several engineering project management modes commonly used in the international and domestic markets and developed in recent years, the author classifies them in the light of the principles mentioned above and gives a classification of the characteristics of various management modes. The characteristics of various management modes are analyzed. In order to illustrate the problems, this paper combines the current relevant research results and gives a sketch of the contract and management coordination relationship between the main parties involved in the project under the various modes.2.3.1 The first type of mode 2.3.1.1 The traditional mode, also known as the design-bidding-construction mode, is a mode whereby the project management company carries out the management in the construction stage of the project and coordinates the relationship between the owner and the construction party. Advantages: the management method is more mature; the owner is free to choose the consultant designers and supervisory units, and can control the design requirements; competing prices through bidding is favorable to the owner; standard contract text can be used. Problems: poor constructability of the design; poor ability of the supervising engineer to control the project objectives; too long construction period; unfavorable to the division of responsibility for construction accidents; disputes due to drawing problems.2.3.1.2 Agency Model In this model, the CM manager acts as the owner's consultant and field agent to provide the owner with services at a certain stage or during the whole process, and the CM manager's job is to be responsible for the coordination between design and construction and the relationship between different contractors. between design and construction and between different contractors. In the agency CM model, the project management company is compensated by a fixed fee plus a management fee. Advantages: Owner can select its own engineering consultant; complete scope of work and project principles can be determined before bidding; complete management and technical support; shorten construction period and save investment. Disadvantages: the CM manager does not guarantee the schedule and cost; the cost of possible claims and changes is high, and the owner is at high risk.2.3.1.3 Project Management ModeWhen an owner has several projects in different stages of implementation at the same time, it is necessary for the project manager to be responsible for a single project from the beginning to the end. The work of each consulting engineer and general contractor is also coordinated and phased. The risks on both sides are similar to those of the traditional model, and the owner has to hire a high-level project manager instead of the traditional model, which is mainly practical for the construction side to carry out multiple projects at the same time.2.3.1.4 Design-Management ModelThis model is that the owner signs separate contracts with the design-management company and the contractor, and the design-management company is responsible for the design and manages the implementation of the project.2.3.1.5 Design-Build, PEC Turnkey Projects Design-Build, PEC Turnkey Model The owner first recruits a professional consulting firm to study and approve the basic requirements of the proposed project, and the owner selects a design-build general contractor to be responsible for the cost of the entire project on a lump-sum contract basis. This model allows the contractor to provide a full range of services from project planning through to completion and handover. The model features: risks are mainly borne by the contractor; reduce the cost of the whole process of construction; minimize disputes and conflicts; can guarantee the quality of the project; the owner has less control over the project.
