The progress control of cement plant construction project refers to the preparation of the optimal construction progress plan within a given construction period. During the implementation of the plan, the actual construction progress is often checked and compared with the planned progress. If there is any deviation, analyze the reasons and the degree of influence on the construction period, find out the necessary adjustment measures, modify the original plan, and so on until the project is completed and accepted. Its overall goal is to ensure the realization of the established target construction period of the construction project, or to shorten the construction period appropriately without increasing the cost.
1 progress control method of cement plant construction project
Mainly planning, control and coordination. Planning is to determine the overall schedule control objectives and sub-schedule control objectives of the construction project, and to prepare the schedule plan. Control is to compare the actual construction progress with the planned progress in the whole process of construction project implementation and adjust the deviation in time. Coordination is to coordinate the progress relationship between units, departments and task groups related to construction progress.
2, cement plant construction project schedule control measures
The main measures are organizational measures, technical measures, contract measures, economic measures and information management measures.
Organizational measures are mainly to implement the specific tasks of schedule control personnel at all levels; Establish an organizational system for schedule control.
According to the structure, progress stage or contract structure of the construction project, decompose the project, determine the progress target and establish the control target system; Determine the schedule control system, such as inspection time, method, coordination meeting time, participants, etc. ; Analysis and prediction of factors affecting progress. The technical measure is to speed up the construction progress. Contract measures refer to the coordination between the contract duration of the construction contract signed by subcontractors and the related progress targets. Economic measures refer to the financial guarantee measures and corresponding incentive measures to realize the progress plan. Information management measures refer to continuously collecting relevant information of actual construction progress, sorting out statistics and comparing them with the planned progress, and providing comparison reports to the construction unit on a regular basis.
3, cement plant construction project schedule control tasks
It is mainly to prepare the general construction schedule and control its implementation, so as to complete the task of the whole construction project on schedule; Prepare the unit project construction progress plan and control its implementation, and complete the unit project construction task on schedule; Prepare the construction progress plan of the branch project, control its implementation, and complete the construction tasks of the branch project on schedule; Prepare quarterly, monthly and ten-day operation plans, control their implementation, and complete the specified progress goals.
Due to the construction characteristics of cement plant construction projects, especially large and complex construction projects, the construction period is long and there are many factors affecting the progress. When planning and implementing the plan to control the construction progress, we must fully understand and estimate these factors, so that the construction progress can proceed as planned as far as possible. When there is deviation, the relevant influencing factors should be considered and the reasons should be analyzed. The main influencing factors are:
(1) Influence of related units
The main construction units of cement plant construction play a decisive role in the construction progress, but owners, design units, bank credit units, materials and equipment supply departments, transportation departments, water and electricity supply departments and relevant government departments may cause difficulties in some aspects of construction and affect the construction progress. Among them, the design unit's drawing is not timely and there are mistakes, and the change of design scheme by relevant departments or owners is the most frequent and influential factor. If materials and equipment cannot be supplied on schedule, or the quality and specifications do not meet the requirements, the construction will be stopped. There is no guarantee that the funds will also interrupt or delay the construction progress.
(2) Changes in conditions
During the construction process, engineering geological conditions and hydrogeological conditions are inconsistent with the exploration design, such as geological faults, caves, underground obstacles or bad weather, rainstorm, high temperature, floods, etc., which all affect the construction progress, resulting in temporary shutdown or partial destruction.
(3) Technical error
Technical accidents due to improper technical measures taken by the construction unit; Lack of experience in applying new technologies, new materials and new structures can not guarantee the quality and will affect the construction progress.
(4) poor organization and management
Unreasonable construction organization, improper deployment of labor and construction machinery, and unreasonable construction plane layout will all affect the implementation of the construction progress plan.
(5) Accidents
If there are unexpected events in the construction process, such as serious natural disasters, fires, major engineering accidents, etc., it will affect the construction progress.
In order to improve the efficiency of cement plant construction, the construction period of cement plant is getting shorter and shorter, but with the continuous improvement of construction technology and means, the ability of construction enterprises is also greatly strengthened, which provides a basis for speeding up the construction progress. However, in order to effectively control the construction period, both the owner and the construction unit should work together to achieve good results.
