By paying attention to the construction preparation of the project and making and optimizing the schedule according to the construction period, the practical application of the construction schedule in the project is ensured.
1 Pay attention to the construction preparation of the project. The construction preparation of an engineering project is an important part of construction production, the overall arrangement of project objectives, resource supply, construction scheme selection, spatial layout and time arrangement, and the fundamental guarantee for the smooth progress of civil construction and equipment installation.
2. According to the requirements of the contract period, it is not only the contract requirement, but also the need to realize the business objectives of the enterprise to prepare the construction progress plan and complete the construction tasks according to the contract period. At this point, the interests of both the construction unit (owner) and the construction unit are completely consistent. Control is to compare the actual value with the planned value, find out the deviation during the period, and then make feedback adjustment. Working out the construction progress plan is to determine a planned value to control the construction period and work out effective measures to ensure the implementation of the plan, so as to ensure the completion of the contract construction period.
2. 1 Selection of project schedule type The preparation of the application schedule is to decide when to do something or when the project will progress to what extent. The types of project progress plans are classified according to their contents, including target plans and support plans. The project construction schedule itself is the most basic target plan, which determines the construction period of the project. In order to achieve this goal, there should be a series of supporting plans, such as material use plan, turnover material use plan,
Mechanical equipment use plan, labor and parts use plan, semi-finished products use plan, etc. In terms of the length of time control, there are general progress plans and phased plans. The master schedule controls the whole process of engineering construction, and the phased plan includes the annual, quarterly and monthly construction schedule and the ten-day and weekly operation schedule of this project. From the form of expression, there are written plans and plane plans. The former uses words to explain the construction tasks of each stage and the image progress requirements to be achieved; The latter uses vivid and concise charts to express the construction progress. As far as I know, the most commonly used are cross planning, network planning and diagonal planning. From the perspective of management scope, there is an overall schedule and a zoning schedule. The master plan is a strategic schedule for the overall project, which is generally rough. Zoning plan is the progress plan of a certain part of the project or a certain professional type of work, which is generally more detailed.
The preparation of project schedule is based on long-term experience in construction production, operation and management and theoretical knowledge of construction schedule control.
3. 1 Contract of this project. The stipulation of the construction period in the contract is the basic basis for determining the planned value of the construction period, and the commencement and completion dates of the project stipulated in the contract must be implemented through the schedule.
3.2 The construction organization design of this project. These data define the construction capacity allocation and construction organization method, reflect the construction characteristics of the project, and thus become the basis for determining the target plan of each stage in the construction process.
3.3 The enterprise's construction, production and operation plan and project schedule plan are an integral part of the enterprise plan, which should obey the guidance of the enterprise management policy and meet the requirements of the enterprise's comprehensive balance.
3.4 Project design schedule. Drawings are the foundation of construction, and the construction progress must be connected with the design progress, and the construction time of corresponding parts must be arranged according to the delivery date of each part of drawings.
3.5 Material and equipment supply plan. If there is already a supply plan for materials, equipment and turnover materials, then the project construction progress must be coordinated with it. In addition to the above five points, we should also consider the preparation of the project schedule as the main basis, and at the same time pay attention to the information about the site construction conditions, including the hydrological, geological, climate and environmental information of the construction site, as well as traffic conditions, energy supply and auxiliary production capacity.
4 The preparation of the project construction schedule network plan has obvious logic, which can not only clearly express the work content and time arrangement in the project control schedule, but also clearly express the internal relations and constraints between the work, and can use digital methods to analyze and optimize the plan, so the network plan has better and more advantages than the horizontal plan. "Network planning technology" has been more and more widely used in the control of construction period of construction enterprises.
