Engineering Construction Organization Design Paper 1

Brief Analysis on Construction Organization Design of Water Conservancy Project Abstract: Water conservancy project is the top priority of a country, and its construction quality and progress have a far-reaching impact on the function of water conservancy project. The purpose of this paper is to discuss the design of the construction organization of water conservancy projects.

Keywords: design and construction of water conservancy projects

1. Definition of the construction organization design of water conservancy projects

The so-called construction organization design is the most basic basis for demonstrating that the design can be feasible and economical in reality, and at the same time it is restricted by natural conditions, social politics and economy, which makes it the most basic basis for the overall design planning and layout of water conservancy construction and the bidding documents. Up to now, the construction of water conservancy project is still a practical subject with experience as the main technology. In the current extremely competitive society, it is of far-reaching significance to strengthen and improve the understanding and research on construction organization design.

Second, the important significance and role played by the construction organization design of water conservancy projects

As a technical document for preparing for the construction of a proposed water conservancy project and preparing for the strategic deployment of construction, the design of construction organization has a very important position.

1. It is a part of the overall design

At present, the survey and design institutions in China have many sub-bureaus, such as geology, surveying, hydrology, who can do it, experiment, hydraulic engineering, construction, electromechanical and budget, which are all parts of the survey and design, and have a special relationship of interdependence and mutual restriction. The design of construction organization is closely related to the layout of hydraulic hub and the characteristics of structural form, and it is also impossible. In some countries in Europe and America, hydraulic engineering and construction are also integrated. Therefore, in the study of the overall design scheme, all the above should cooperate with each other, coordinate with each other, carefully analyze and study, so as to get a technically feasible and economically reasonable overall design scheme.

2. It is an important factor in making decisions on engineering construction.

When we talk about engineering construction decisions, we need not only the goals of regional electricity load, irrigation, water supply and comprehensive utilization, but also the hydrology and electromechanical majors to calculate the effects of engineering investment separately, and we should also analyze and calculate the natural conditions, social economy, financial sources and the length of construction period in the region where the project is located, and provide the basis for engineering construction investment estimation. Among them, the investment of hydraulic engineering and construction teams has a great influence, especially the construction specialty. Increasing the static and dynamic investment of temporary construction projects and changes in construction period are all used as the basis of economic analysis, which is conducive to the rational decision-making of the project construction site.

3. It is the main basis for the reserve and layout of the preparatory construction project.

In the construction preparation of the project, the planning of the material yard, the facilities of the project, the living building, the construction equipment, the materials and equipment and the installation site all need to be strictly planned and arranged, and the projects involving inundation, land occupation, resettlement and environmental protection are involved. The contractor carries out the preparatory preparation according to the construction organization design, so as to facilitate the overall arrangement. And more importantly, the design of the construction organization is a guide to the construction, which is conducive to grasping the key procedures and coordinating funds reasonably, giving full play to the labor force, completing the planned investment and corresponding construction tasks in stages on schedule with high quality and high yield, and creating good conditions for the construction of the project to play its benefits in advance.

4. It is an important basis for construction and management.

In the past, China's engineering construction was guided by planned economy, and mandatory distribution engineering design and construction were adopted. However, in the current national form, the bidding method of design and construction is gradually implemented, and the design system should be changed accordingly to adapt to the rapid development of market economy.

Among them, the task of construction organization design is to work out the overall design scheme for technical feasibility development and economic and reasonable arrangement in coordination with other design majors, and submit the feasibility report document. Besides, it is also necessary to adapt to the modern bidding method, provide the owners with economic and sound bidding technology, and provide services for the preparation, preparation and strategic deployment of the project. Therefore, the design of construction organization is not only the economic basis for the owner as a bidding technology, but also the most powerful basis for the contractor to deploy the construction strategy and guide the construction technology, and its importance is self-evident.

III. Basic contents of construction organization design of water conservancy projects

Due to the different stages of construction design, construction design can be divided into pre-bid design (that is, design before bidding) and post-bid design (that is, design after bidding). According to the object of construction organization design, construction organization design can be divided into general design, single construction organization design and division construction organization design. The basic contents of construction organization design include construction diversion, construction technology, construction progress and construction layout.

(1) Construction diversion

The water conservancy project is built on the river of the water source, so there is a contradiction between its construction and the river water. In order to solve this contradiction, some or even all of the river water must be diverted to form dry land construction conditions, and the conditions for comprehensive utilization of the river will not be damaged as far as possible, so it is necessary to put forward a special design for construction diversion. Construction diversion is an important factor in selecting dam site, hub layout, dam structure and construction method, construction progress and construction layout in water conservancy project design, and it is also the central link of the whole construction organization design.

Therefore, it is the main key to control the construction period and an important factor affecting the total investment of the project. The construction of water conservancy projects needs to adapt to natural conditions, so the most important thing is that it should adapt to the laws of water regime. Under normal circumstances, the cost of adapting to the water regime law is much less than that of changing the water regime law, and in many cases, the water regime law is difficult to change or even cannot be changed, so the construction diversion has become a control link in the construction of the main project, and in the diversion project, interception, drainage, flood crossing, plugging, flood prevention and water storage have all become the construction control factors of the main project.

obviously, if the construction procedures and river laws of the main project can be well adapted and the project is progressing smoothly, then expenses can be saved. However, if this is not done, it will not only disrupt the construction plan, so that the construction period will be delayed and the expenses will be increased, but also cause accidents and forced shutdown, which will seriously affect the construction of water conservancy projects. In the case of special construction technology and equipment, the construction period of water conservancy projects depends on the number of projects and the conditions of construction diversion. This is because the project cost of diversion can be inversely proportional to the construction period, so construction diversion is still the main factor to control the construction period.

it should be specially noted that river closure is a key link in the design of diversion for our construction, and it is also an important procedure for the construction of the main project. Only when the diversion building is completed can the conditions for diversion be met, so the prerequisite for river closure is diversion, and the diversion project is realized by the diversion measures and water retaining cofferdam.

(2) Construction method

The foundation of construction organization design is the construction method, which is completed by the construction technology, construction sequence and construction technology with specific construction equipment. The construction method is important because it is a synthesis of the feasibility and economic rationality of the post-construction technology of the structure of the building, and its research projects are basically the following:

2.1 The characteristics of the construction technology of the building with its implementation sequence and methods are studied.

2.2 study the sequence of building construction of the main project and the technical characteristics of the implementation situation matched by the construction diversion.

2.3 with the support of specific technical equipment, study the reasonable index of low construction intensity that can be achieved within the construction period.

2.4 research and study the rational layout of the site suitable for the construction plane and elevation of the construction procedure.

2.5 study the supply of necessary technical materials and the consumption of materials, and provide basic data for budget analysis of unit price.

2.6 to study the scientific management of construction safety, quality, progress and benefit, and the construction technology and requirements.

(3) the progress of construction

The progress of planned construction is from the start of construction preparation to the completion of the project site. During the whole construction period, the relationship between the construction procedures, construction speed and technology supply of all the individual projects in the construction site, and the indicators of overall planning time and intensity shown through comprehensive coordination and balance, the current progress plan is expressed in the form of horizontal line diagram, diagonal line diagram and network diagram. Then, in the planning and research of construction progress, the key problems to be solved are:

3.1 The construction procedures should be reasonably divided. It is in the water conservancy project that the period that has a great influence on the construction degree needs to be reasonably divided, such as river closure, flood crossing, plugging, flood interception and water storage period, so that it can be properly arranged and reasonably divided.

3.2 level of construction mechanization. Machinery and equipment need to adapt to the natural conditions of the project and the characteristics of the building. The procedures of construction machinery and equipment have an impact on the construction intensity, and will directly affect the construction speed and project progress.

3.3 control of key construction period. Through the construction practice of water conservancy projects, it can be found that the exchange of the whole project schedule is controlled if the river closure starts at the beginning and the construction period of the first dry season in the later period. Therefore, at the same time of arranging the progress plan, the construction methods and methods of the diversion buildings before the closure and the dam after the closure should be fully demonstrated, including the closure, foundation pit drainage and foundation treatment, and dam filling, so as to achieve reasonable and safe flood control and divide the key construction periods.

3.4 the effect of economic investment. Because there are many water conservancy projects, complex jobs, large quantities, long construction period, far away from towns and huge investment, there are many difficulties in the planning of its progress, and there are many changing factors. The relationship between its progress plan and the investment of resources and time is closer, and the degree of influence is also increased, which requires the planning of progress to make full use of resources and resources to achieve the best economic effect.

Engineering Construction Organization Design Paper 2

Talking about Compiling Construction Organization Design of Building Engineering

Abstract: This paper analyzes the situation that should be paid attention to in the process of compiling construction organization design of building engineering, and strives to organize the construction of the project in the most effective, economical, reasonable, rhythmic, civilized and safe way, so as to realize the project with good quality and quantity, quickly and safely.

Keywords: preparation; Reasonable; Scientific arrangement

The construction organization design of a building project is a global guiding document based on the preliminary design or expanded preliminary design drawings, other relevant materials and on-site construction conditions, which is used to guide the whole construction project or group project to carry out construction procedures and organize construction activities. It is the basis for construction enterprises to establish construction conditions, assemble construction forces, organize the supply of materials and resources, and plan temporary facilities for on-site production and living. It is also the basis for construction enterprises to formulate annual construction plans and organizational design of unit projects, and it is an effective measure for construction enterprises to realize scientific management and ensure the optimal completion of construction tasks.

in my daily work, I found that the compilation of this part determines the rationality of the whole project construction and plays an important role in the completion of the project. Therefore, in view of compiling the construction organization design of building projects, the following points are discussed:

1. Abide by relevant laws and regulations

China has promulgated a series of laws and regulations on the construction of building projects, and the project can only be started after it has been approved by the relevant departments. Therefore, when compiling the construction organization design, it is necessary to strictly abide by laws and regulations and conscientiously implement the relevant provisions of capital construction, which is the basic condition for compiling all construction organization designs.

2. Strictly carry out construction procedures

Every project has strict construction procedures, which is the basic core to ensure the smooth progress of construction. If the normal construction procedures are violated, the objective construction procedures will be changed at will according to your own subjective imagination, which will not only fail to speed up production, but will lead to serious safety consequences. Therefore, when compiling the construction organization design, the basic project construction procedures must be strictly observed, and the person who compiles the construction organization design should also have a very clear understanding of the actual construction of the project.

3. Comparison method of construction organization scheme

The selection of construction scheme must be compared with multiple schemes. When comparing, be sure to seek truth from facts, and avoid formally demonstrating an established scheme. The purpose of comparison is to choose the most economical and reasonable scheme among multiple schemes. The current new construction technology often involves factors such as design and building materials, and all aspects should cooperate closely. It must be pointed out that adopting new technology is not the purpose, but the purpose is to obtain the optimal index scheme. Therefore, we must proceed from reality and never copy it mechanically. For some traditional methods that are still effective at present, as long as the indicators obtained in the scheme election are good, they are still excellent schemes. Of course, we should also pay attention to the development direction of a new technology in the comparison of schemes. If the promotion of a new technology is not obvious or even good because of some habits or immature objective conditions, as long as the final direction is correct, we should allow the pilot to be carried out and improve in practice, and finally achieve the goal.

4. Scientifically arrange the construction plan

The construction plan is the most important part of the construction organization design document. The calculation and supply of all resources on the construction site, the arrangement of various business organizations and the layout of the construction site plan should be based on the construction plan, which is arranged according to the requirements of specific projects on the basis of the prioritized construction plan.

the construction plan of any project, that is, the construction sequence of each sub-project and type of work in the project, must have certain objective laws, that is, the overall arrangement of a series of construction activities in the space and time of the project. Some should be connected in sequence, some can be overlapped, and some should have a certain period of technical intermission. These are the objective laws of construction. In order to shorten the construction period, interchange or parallel construction can also be organized. Sometimes, in order to get the balance of some resources, we can organize flow construction or artificially extend or adjust the duration of a certain type of work.

in addition, there is also a problem of sequence between different parts of the project, such as underground first and above ground later; Do the foundation first, then do the main structure, and then do the decoration engineering. However, if there is no reasonable plan in actual construction, it will also be reversed, resulting in a series of losses and waste.

5. Adopt advanced construction technology and equipment

Try to adopt advanced science and technology to improve the construction level. In building construction, the key to improve labor productivity, shorten construction period, improve project quality and reduce project cost and consumption is to adopt advanced construction.
