1、A Study on the Engineering Construction Schedule ControlSong Shihai （重庆建工机电安装工程有限公司 400039） （Chongqing Construction Mechanical and Electrical Installation Engineering Co., LTD 400039） Abstract: In the whole process of engineering construction, its schedule control is a very important part, which not
2、 only directly affects the quality of the whole project, but also plays a very important role in the economic effect of the entire project. Meanwhile, in the particular process of engineering construction, since construction is a dynamic process, coupled with the numerous factors that involved in th
3、e engineering construction schedule control and the program is quite complex, it is so imperative to put the factors and program involved in order; and from a dynamic point of view, the construction schedule control can be studied and analyzed in a comprehensive way. The paper begins with the study
4、of relative definitions of engineering construction schedule control and illustrates the involved factors and the corresponding influence of them on the engineering construction schedule control based on the case study of real estate project construction schedule control at Fuyuan Jiayuan of Taian C
5、ity. And some related suggestions are put forward on the base and the author expects to make an active theoretical guidance effect on engineering construction. Key words: Engineering Construction; Schedule Control; Measures; Factors 1 Introduction Engineering project management is very complex and p
6、ractical work, whose core contents are generally composed of project schedule management, project quality management and project investment management. In these three core contents, the engineering project schedule management is the center, which plays a vital role in the entire construction of the
7、project. However, the engineering construction schedule management control is the core of the project; therefore, carrying out the study of construction schedule control is an important prerequisite of a good project management. The project management content a bit numerous, including scope manageme
8、nt, cost management, quality management, personnel management, schedule management and other aspects, and because the project subject is influenced by many factors, in the particular implementation progress, there are a great many uncertainties, so the small mistakes of management may cause schedule
9、 to delay and cost to overrun, leading to the decline of program economic benefits and even the failure of the entire project, therefore, this paper analyzes and discusses the construction schedule control and the author expects to find out the relevant factors that influences the engineering constr
10、uction schedule, and on this basis, some ideas are put forward about how to control these factors and thus better control of construction schedule. 2 Related Overview of the Construction Schedule Control 2.1 Related Concepts of Construction Schedule Control Construction schedule control mainly refer
11、s to the strengthening of management of various factors that affect the construction schedule and taking all effective measures to strictly control the construction process of the program in a certain range, to making sure the achievement of the construction schedule management goals in the process
12、of the construction. Specifically, it means making certain plans of work content, work procedures, duration, and cohesive relations at each stages of engineering project construction. The plans should be implemented; in the course of implementation, it is necessary to check that whether the actual p
13、rogress is conducted according to plan requirements; the reasons for the deviations should be analyzed, remedial measures or adjust should be taken; the original plan should be modified until the project is completed and delivered. Construction schedule control is the focus and core of the whole pro
14、ject management, which runs through the project from the beginning until the whole process of completion and acceptance of the tender stage. 2.2 The Contents that Included in Construction Schedule Control, Due to the fact that construction control goes throughout the whole process of construction, i
15、t includes more contents, such as the controls of pre-construction and construction control in the progress and a control after construction progress, which mainly includes, firstly, determining the content and characteristics of the schedule control work and, control methods and specific measures,
16、risk analysis of schedule aim achievement, as well as what other unsolved issues; secondly, making plans of overall schedule of construction organization and making time arrangement of the construction preparation work and various tasks; thirdly, making plans of project schedule; fourthly, making pl
17、ans of the annual, quarterly, monthly projects. During the period of construction, schedule control is mainly based on the changes of the duration of every construction process and the increase and decrease in construction content that caused by design changes, the changes in internal construction c
18、onditions and external conditions, timely analysis, taking appropriate measures. Schedule control after construction progress mainly refers to the work after the completion of construction work, including: organization engineering inspection, process engineering claims, data compilation, classificat
19、ion, cataloging and archiving of project schedule and so on. 2.3 Significance of Construction Schedule Control Construction schedule control is an important task of in engineering construction management and an essential indispensable part of the whole project, which has a significant role in the en
20、tire engineering construction. Meanwhile, engineering construction schedule control is a relatively complex process that not only involves the duration of the project, but also includes the influences of workload of the engineering and resource consumption; and from the relational point of view, the
21、se factors of the construction schedule control are mutually affected and interrelated; therefore, to make a good construction schedule control, it is a must to control it from multiple perspectives so that the construction schedule and project implementation condition can be evaluated properly. Con
22、ducting the engineering construction schedule control has a very important theoretical and practical significance, in theory, making good construction schedule control is the basis for project management, and it can greatly improve the project management level and acts as reference for the whole pro
23、ject management. From a practical sense, making good engineering construction schedule control can make full use of limited resources, improve the efficiency of the whole construction, cost savings and improve the economic benefits of the whole project. 3. Main Measures of Engineering Construction S
24、chedule Control 3.1 The Mode and Organizational Structure of Making Engineering Schedule Management In terms of Fuyuan Jiayuan real estate of Taian City, a main reason why some problems of this project come out in the process of engineering construction schedule control is that it a failure to build
25、 a progress management model and organizational structure in a good way, resulting in some issues of the emergence of labor shortages, engineering rework and uncompleted coordination work. When it comes to the establishment of mode and organizational structure of the project schedule management mode
26、l and, it firstly needs to establish an efficient management team which plays an indispensable role in the construction schedule control, such as the staff assignments, operating mode, operating procedures, operational systems of project construction and a high standard of management objective are b
27、etter achieved through an efficient management team, making a variety of units in charge of construction such as the civil engineering, strong power, weak power, air conditioning, steel structure, installation well coordinate during operation an the whole progress of the project is well controlled.
28、In the second place, making the mode and organizational structure of project schedule management needs to establish an efficient project team at the beginning of project construction. 3.2 Working out Feasible Construction Schedule Plans In terms of the Fuyuan Jiayuan real estate of Taian City, anoth
29、er important reason why some problems emerge in the process of construction schedule control is that the lack of feasibility of the construction schedule plan, leading to a big difference between project time of the overall plan chart of Taian City Fuyuan Jiayuan real estate project and specific con
30、struction time. Fundamentally speaking, working out feasible construction schedule plan is to make the schedule possesses the feasibility and suitability and project department needs to draw up and verify according to some actual conditions such as project scale and fixed duration for the days for c
31、onstruction. For instance, in terms of Fuyuan Jiayuan real estate project of Taian City, in the preparation of the construction schedule, it is necessary to take full account of the relevant factors, such as to give full consideration to the time factors of Spring Festival as well as harvest. The sc
32、hedule are mainly worked out and verified from the following aspects: firstly, whether the total project goals and sub goals meet the contract requirements; secondly, whether the subentry project of construction has the phenomenon of omission; thirdly, whether the project construction arrangement me
33、ets the requirements of the construction sequence; fourthly, whether the project construction process, materials, labor, machinery, parts, equipment, and other supply plan meet the needs of the engineering phase; fifthly, whether the co-ordination of various professional articulations are in place i
34、n the process of project construction; sixthly, the condition of funds supply supplication of owners in the project construction process. 3.3 The Implementation of the Construction Schedule In terms of Fuyuan Jiayuan real estate of Taian City, the bad implementation of construction schedule is a sig
35、nificant reason that leads to the failure of construction schedule, at the same time, in the process of construction of the project, some construction schedule that has not been well implemented are not given related adjustment measures, but allows the duration of the delay, for example, in the cour
36、se of implementation, since coordination is not in place, strong electrical construction has not completed, leading to delays for air conditioning installation. From the point of view of construction schedule control procedures, the implementation of the project construction schedule is actually a k
37、ind of fulfillment of construction schedule. Therefore, the project manager should regularly and frequently conduct inspection and supervision of the construction schedule implementation. In the meanwhile, in the inspection and supervision process, if a problem occurs, it is necessary to adjust the
38、construction schedule and construction programs according to the actual situation of construction in a timely manner, ensuring the implementation of the whole days for construction. Adjustment methods include two kinds: one is to shorten the days for construction by compressing the duration of the c
39、onstruction period. The other is to shorten the days for construction through the organization of overlapping jobs or parallel jobs. According to the project situation, the above two methods can also be adjusted in the same construction segment. At the same time, the coordination work of constructio
40、n project should be done actively. Specifically speaking, mainly based on the master of implementation of the plan, the relationship among various units should be coordinated to so exclude contradictions timely, overcome weaknesses links and ensure the aim achievement of the operational plan and schedule control. 3.4 Focus on Technical solutions From Fuyuan Jiayuan real estate project of Taian city, the reasons why the construction schedule is not well implemented and why there are trouble in schedule control are
