Web-based project management based on network system (hereinafter referred to as WBPM) supports the use of network information technology to establish a central database, provide engineering information services, promote the exchange and cooperation of all project participants, and constantly update the data in the database, so that owners, architects, structural engineers and contractors can grasp the current situation of the project in time and make analysis and decisions in time. In this way, the main factors affecting the project construction can be integrated, and the project can be successfully completed by strengthening exchanges and cooperation among project participants.
1 WBPM management model;
WBPM management mode should first build a local network system, which includes the following components: network engineering center, communication platform system, network security system and user system. Then the local area network is embedded into the internet through the router, which can realize remote project control and management. The functions of each part of the LAN are summarized as follows.
Network engineering center: central database: storing and processing engineering information, including engineering overview, material use, engineering equipment use, engineering progress and other information; Can generate quality control, investment control and other stages of the schedule, and related calculations and analysis.
Archives management: record and query all kinds of documents related to the project, including project contract management, design changes, instructions issued by supervision engineers, meeting minutes, etc. , and manage various documents.
CAD Gallery: Stores architectural design, structural design, water supply and drainage, HVAC and other design drawings of building equipment for query.
Communication platform system: instruction system, the project department or supervision engineer can issue construction or supervision instructions according to the progress of the project to control the construction site in real time.
Mail receiving and dispatching system: all participants in the project can exchange information at any time and strengthen coordination and cooperation.
Network security system: through the necessary security verification of users who log in to the system, identify the types and permissions of users and ensure the security of the system.
Users: it can be owners, architects, structural engineers, builders, subcontractors at all levels and other contractors of all projects. Users can get information through the network and strengthen communication and contact. Users can also upload information and have the right to control the openness of the transmitted information. The LAN system should be maintained and managed by special personnel, and the central database should be updated in time to sort out all kinds of documents.
2 WBPM management mode needs technology and implementation.
The realization of project management mode needs the technical support of network information and supporting hardware facilities. It first requires technicians to master VB programming language, design, develop and maintain databases with VFP or SQL, and design and develop networks with HTML or JAVA programming language. In terms of hardware, it is necessary to have client/server, browser and network architecture that can realize this technology.
Once an enterprise decides to adopt a network-supported management mode, there are usually two ways to achieve it:
(1) Enterprises rely on their own resources and technological advantages to independently develop systems and install and maintain them themselves.
(2) Enterprises employ professional technicians to develop, research and install systems, provide technical training for system maintenance personnel or purchase network-supported engineering management software. In the first case, the enterprise must invest a lot of manpower and financial resources to develop technology and maintain the system. Its advantage lies in its independent property rights and high security. In the second case, the enterprise can get the system only by paying the fee, but it still needs to carry out technical training for the managers.
Advantages of 3WBPM management mode
Large-capacity information storage provides convenience and powerful information processing functions for all parties involved in the construction and supports system decision-making. This mode can track and record the implementation of the contract, which is convenient for the project management department to control the project progress and investment; In the process of construction and management, the procedures can be simplified, and the project manager or supervision engineer can send instructions by fax or email to obtain information; For enterprises, it is convenient and quick to obtain the information of all reconstruction projects, which is convenient for unified management and coordination; Because the whole management process adopts automatic information processing, it not only saves the cost, but also optimizes the management process. The rapid circulation of information facilitates the communication between participating units and saves costs. Participants in the project can keep abreast of the current situation of the project through constantly updated online information, make full preparations for the next process, strengthen the process connection, and provide guarantee for the timely and quality completion of the project; Rapid information transmission can ensure that the project management department and supervision engineer can grasp and control the project in real time; The smooth flow of information can make the construction parties maintain good relations, thus reducing the possibility of disputes in the project. Even if there is a contradiction, you can easily find the problem through the records and files of the project, saving a lot of investigation expenses. The centralization and completeness of information greatly reduces the time to find information, improves the efficiency of work and decision-making, thus speeding up the progress of project implementation and shortening the time of project construction.
The smooth communication of information improves the foresight of decision makers on project implementation, can effectively control the interference in the process of project implementation and reduce the risk of project implementation. Remote project control and management can be realized by using network to transmit information. Webcor, a famous American construction company, is a large construction contracting company. It built an office building with 12 floors in California, with a total contract value of $50 million. Its owner is in new york, its design unit is in San Francisco, and contractors for other projects are also distributed all over the United States. Due to the adoption of network management mode, nearly 50 thousand dollars of information and communication expenses have been saved. The president of this company thinks that if all subcontractors adopt this system, the information communication cost can be saved by 200,000 dollars.
4 network technology in project management application prospects
Using network technology to summarize information, exchange and process computer information, so that construction workers can manage engineering projects supported by network systems through the Internet. Many construction enterprises around the world have begun to use or try to use this technology, the main reasons are as follows: First, this model optimizes the management process, saves time, reduces production costs, and brings competitive advantages to enterprises. Second, the owner has requested or used the management system, so the construction management party has to adopt the system.
In the exploration of applying computer information technology to project management at home and abroad, P3 software developed by Primavea Company in the United States has a high market share. At present, almost all large and super-large projects in China have adopted this software for project management. This software series has the functions of managing multiple projects at the same time through various views and tables, analyzing and making decisions through the combination of open database and other systems, automatically generating 100 standard reports for document management, and transmitting information and communication through e-mail. Microsoft Project, launched by Microsoft Corporation, is a project management software with progress as the core, which is widely used in the world at present. It is also the product of the combination of the powerful function of computer network information management and engineering project management, which can realize remote management and control. In China, some software companies have developed some project management software for a certain process of project management or from the perspective of a project participant, such as the software developed from the perspective of supervision and project manager, which has the characteristics of specialization and strong pertinence, but still cannot realize the ability of rapid multi-party communication and remote control and management. It can be predicted that the application of network technology in project management will bring revolutionary changes to project management and lead the whole construction industry to the road of informationization.
5 concluding remarks
Adopting the project management mode based on network system as the basic means of project construction and management not only improves the efficiency of information processing, strengthens the communication and coordination among project participants, shortens the construction period and saves costs, but also standardizes the process of project management to a certain extent, improving the efficiency of project management and the effectiveness of target control. It can promote the integration of China's construction industry with the international construction industry and meet the challenge of China's entry into WTO.
