Discussion on the importance of project management in
construction organization design
Abstract: The construction organization is a construction project and guide the importanttechnical and economic documents. Can regulate the construction workers, machinery, raw materials, environment, technology, equipment,construction, installation, management, production and other conflicts, to supervise the construction and control of organizational design in order to ensure scientific and rational project high-quality, low cost, less the completion of energy.
Keywords: project management; construction organization; design; importance
Construction design and project construction is an important document guiding construction, construction enterprises are able to high-quality, high speed, low cost, low consumption of completed building projects to ensure effective measures, but also strengthen the management, the importance of improving economic efficiency means, is also properly handle the construction workers, machinery, raw materials, methods, environment and technology and equipment, civil works and installation of collaboration, consumption and supply, management and production and other kinds of contradictions, scientific and rational, planned and orderly , the equilibrium organization of production and an important guarantee for project construction.
With the establishment of socialist market economy, an increasingly competitive construction market, the objective situation of construction enterprises have become increasingly demanding, not only in technology and equipment, personnel quality, the construction put forward higher requirements of the organizers, and engineering economic management Pre-settlement work in the project is also facing new challenges. Strict construction market situation, some construction companies are not actively taken measures, professional and technical staff is not updated, training, science and technology management level is very backward, with the preparation of construction design review did not attract enough attention, so there will be the following common situations:
(1) audit is not compiled before the start of construction organization design: not to pursue the construction of floor plans, materials, cluttered, moving out of import of machinery and equipment, unplanned demand for labor, quality, security, construction without assurance measures, resulting in nest Workers serious waste management lower.
(2) whether it is the preparation of construction design professionals: In order to cope with the higher authorities and supervisory agencies, Party member or check the information to the construction workers on behalf of the Code construction design, because the data simply do not know right now who is a leading construction management recent arrangements, had casually made up, just go.
(3) the preparation of the low level of construction organization design: Some construction units, construction organizations do not understand the importance of the
construction process, to write about the sub-construction process, draw a floor plan, schedule progress, it regarded construction organization design.
(4) to abandon technology economy: a considerable number of construction enterprises in the preparation of construction organization design, construction organization which only concerned the various sub-project of the technical measures, without considering the sub-project aspects of economic indicators, leading to the completion of settlement disputes about economic loss.
[Example 1] in a district of Nanning City, the life of a dormitory building to be a form of water renovation project, but because the dormitory was built in the eighties, has been twenty years, the owners between buildings without authorization of their own debris occupied the public space of normal channels, resulting in too narrow passage between two buildings, traffic problems, so the resulting need for manual handling of construction materials to construction sites, construction materials are stated not to enter the venue and request for additional materials secondary transportation fee, Party A will not sign recognition, resulting in economic losses. If the construction units in the field before the start of the investigation, carefully review the preparation of construction design and engineering contract be described in the notes, you can reduce unnecessary trouble.
[Example 2] of a residential building project excavation, construction site is not large, the construction unit construction with construction design, but no earth survey program, no excavation of the slope coefficient of discharge, nor the accumulation of pre-construction earthwork calculation, the original machine in the pit excavation uppercut on it, because there is no construction design survey on the ground, resulting in ruptured a nearby residential building to the water, resulting in increased costs of grading required to show there is no clear , resulting in a Jixietaiban increase moving away more, but also back when the backfill backfill, resulting in construction enterprises in the economy by the economic loss in vain.
[Example 3] Construction of a residential building products business in the construction process, when preparing to start construction organization is very simple, even the template sub-project calculations are not, in the basement of the construction of the installation template template installation height of 5 m, maximum beam for the 600 × 1200, thickness 250, in the erection of experience by the workers under their erection, supervision and acceptance can not be acceptance of the results, but also re-checking, the results support the strength of pole did not meet the template requirements of a full return to work. Rework the economic losses can be imagined. Such as steel is now more fitting to discuss the situation, the tender list or did not say by welding sleeve, you said in the welding construction organization, it can talk with the sleeve construction of a visa; Earthwork and temporary facilities in the Shih group calculated as long as the excess of the quota rules set paved the way is part of the claim. The problem is now that this file is isolated, not construction, not cost, because it is not targeted.
The above three examples fully show that the construction design in the construction process as well as pre-settlement project plays an important role, not only organized
the construction of organizational design, guiding production role in the objective economic management has become a very important can not be ignored component. Construction design is the arrangement of a construction company building a comprehensive technical and economic documentation of construction products. The depth of the content of their preparation, can be divided into construction design, construction organization design, construction design outline and so on.
Meaning: in order to process the entire project implementation macro-control. Complete the construction of a sub-organization design should include: project overview, construction methods, quality assurance measures, manpower and machinery plan and guarantee measures, construction of network diagrams, and bar charts, safety measures, details of resources, energy conservation measures, construction period to ensure measures.
Implementation of the project in the construction of the session, the price of construction projects through the construction drawings to determine the general preparation of the budget, the determination of the construction contract price, engineering and project final settlement price to determine price and other processes. Construction design of which is the main factor of the project cost, therefore, project cost management, construction design must pay close attention as an important link in this regard should address the following two aspects of the relations.
Fixed construction budget to reflect the actual construction of each sub-part of the construction process of each project component of labor, materials, Jixietaiban consumption standards. It is to identify and control the construction and installation cost base; is to design technical and economic comparison, based on technical and economic analysis; is the construction unit based on the analysis of economic activities; the preparation of bidding price, bidding price of the base; is the preparation of the fixed budget and estimates based on indicators; is construction drawing budget, project contracts, project budget and project an important basis for final prices, but the budget is fixed under normal construction conditions, the majority of the construction unit to the current level of machinery and equipment, the reasonable construction period , construction technology, labor organizations based on each sub-part of the preparation of the consumption of the project. However, construction of the project there are many special cases in which sub-part of the project construction method is not necessarily the same under a fixed budget, as currently stipulated in the budget scale, \Such as \the earth and stone work on the manual calculation rules. Trench digging, earthwork grading time required to \design\shall be calculated, \design\no clearly defined, put the slope coefficient by a fixed proportion of the implementation of the provisions.
Construction projects with construction design is closely related to project cost. The basic construction design includes: project overview and analysis of construction conditions, construction programs, construction technology, construction schedule, construction general layout. There are economic analysis and construction preparation work plan. Among them, the construction program and construction process is more
important to determine, for example: the choice of construction machinery, horizontal transport method of choice, moving the main structure of the construction methods and construction methods and construction technology of choice, etc., are a direct impact on project budget price changes. In ensuring the quality and meet the owners requirements and schedule requirements of the premise, optimize the construction program and construction process is to control the cost of investment projects and reduce the importance of measures and means.
Construction design is not only an important guiding document production and management activities, preparation of construction plans is an important basis for the budget. Therefore, the construction unit leaders before the start of the unit project to tissue engineering, materials and equipment, industrial scale, economic planning, project cost and other personnel to seriously familiar with the drawings, in-depth on-site field survey of the technical and economic organizational measures. Project cost in the preparation of construction design is directly related to the economic interests of enterprises, because, in the project cost management and implementation of the provisions of the budget scale, the cost of personnel staff plays the role of business manager in charge; in the bidding and construction contract, the cost commissioned by the enterprise legal person can be used as the legal representative of the agent, the exercise of powers conferred by enterprise legal person; in the construction and budget work, supervision plays a role in the economy. Therefore, the full cost of in-house staff not only understands technology, understand the policy, but also understands the role of legal expertise and is prepared well construction design and improve an important aspect of economic efficiency of enterprises, but also works to overcome and avoid an economic dispute settlement reasonable and effective way. Finally, the construction organization of this document is very important, it is the technical and economic documents. Construction of the project, be sure to supervise the construction and control of organizational design to ensure the project's construction order, to prevent the construction design a mere formality. Engineering construction design is the quality, safety, effective measures to guarantee progress.
