Budget estimate of the importance of building works

[Paper Keywords] shall budget preparation, project cost

[Abstract] At present, management of construction project cost management system, valuation methods, valuation basis and has done a lot of management tools such as the reform of the budget estimate to use for many years into the fixed guide from the mandatory, according to market prices and Science reasonable allocation of resources to predict construction costs, construction and implementation phase of the project to introduce competition and incentives to save investment and reduce the cost.

First, the budget estimate to improve the quality of the measures
(A strengthening management
In order to improve the quality of work budget estimate, the management of the budget estimate of the static to dynamic management of change "check type" to "preventive", review and find the budget estimate process error-prone because of budget estimate should give high priority attention, as a preventive measure. At the same time change "check type" for the overall management of the whole process of full and strict implementation of the "three links" management procedures (ie, prior guidance, intermediate inspection, finished school trial), according to the process of budget estimate of the actual situation, the impact of budget estimate of the quality characteristics, or weaknesses in key positions set the calculation of basic unit price, unit price table for individual projects and investment in three "management point." budget estimate the impact of quality constraints nipped in the bud, to achieve the quality of case-based self-control, while a "quality information card", check out the problems of the middle one by one record, analyze the causes and develop strategies to achieve improved product quality budget estimate purposes.

(B improve people's quality
In the past the traditional quality management, quality awareness of the quality tends to narrow the concept of people's quality, quality of work short shrift. Because the budget estimate did not like the design drawing, local changes will not affect the overall situation. Shall not budget for staff responsible strong, and once the price is wrong, work is not careful, rates, decimal point, such as wrong numbers is reversed, which would have led all the preparation work must rework, causing human and material waste, the design results in a delay in the case of time. Therefore, we must implement the "prevention first, combining prevention inspection, focusing on improving" the management principle. in the budget estimate process has paid attention to human factors, by improving people's quality to improve project quality, by improving the quality of work to ensure product quality.

As construction projects in various forms, a wide range of ever-changing construction elements, construction methods varied, is very familiar with the budget estimate for the preparation of personnel in the work there will be some omissions inevitably encounter some difficult and thorny issue, coupled with the current new materials, new techniques, new methods and new technologies are emerging, we must access large amounts of data to relearn new knowledge in order to better budget estimate to complete the task. Therefore, to improve the quality of people, strengthening sense of responsibility is very important.

(C strict accordance with the preparation of budgetary estimate of order
Estimate and budget preparation must follow certain procedures, namely: (1 to collect information, develop a work plan, (2 computing unit, (3 individual project budget preparation and budget estimate of total aggregated three steps to complete.

(D preparation of computer applications
Construction budget estimate is a consistent and strong, large and very cumbersome calculation reproduces the work. In the past, manual preparation, the estimate and budget staff had fixed a large number of entries and a variety of computation between the repeated copying and proofreading, in the calculation of a large number of simple repeat spent a lot of work, time and effort, not only inefficient, slow, and often wrong, and the related design work is very coordinated. In this case, to improve and enhance Overview budgeting tool is very important. With the deepening of China's economic reform, construction and design industry is the design phase into the highly competitive market, the design unit in order to capture the market and broaden the market, to design high-quality units made timely and accurate The design results, to improve their credibility, project budget as an important pArt of the design is pArticularly critical. building construction project bidding has been widely used form of construction units and construction also requires enterprises to timely and accurate preparation of engineering control prices and the tender offer. These are required to estimate and budget work big improvement, to change the traditional manual approach, the calculation using the modern computer tools to assist completion of the construction project budget preparation is necessary. This is to raise almost budgeting efficiency and quality of the fundamental guarantee.

(E preparation process should pay attention to the problem
1. Artificial eArthwork calculation of distance, according to the downhill folding distance (see scale provided in the appendix) calculated accurately, especially Watian whichever pArty should break away from the center of gravity, do not take the conversion coefficient at the maximum depth, and After the break away from the distance should be fixed in the unit.

2. Hole dug inside and outside the cave in the rock to calculate the distance.

3. Earthwork transport should "install, play, unloading," the distance account, or easily re-count.

4. Code table in the consolidated number of fixed price, pay attention to their unit, must be divided into different units of the same unit. That is, to pay attention to the natural side, loose side, real side of the difference between the conversion coefficient of the corresponding appendix in both the fixed should be familiar with and master.

5. Dangerous goods, freight unit of freight not only high, but must consider the gross factor coefficient of 1.35 and 0.8 can not be loaded (refer to road transportation).

6. Fixed the height factor regulations, combined with height adjustment of the actual location of the project scale, otherwise the height of the artificial, mechanical efficiency will be ignored, resulting in project budget can not hold.

7. Unit price calculated on the basis table must write clear, simple, complete, or, when the time-consuming proofreading, review can not tell.

Second, the impact of project investment of several factors
(A material budget price
In construction materials used in the wide variety of different specifications, in the preparation of materials, not one by one when the budget price of detailed calculations, but the largest amount of the construction process or the amount is small but very expensive cost of the project have a greater affected part of the material as the main material, a common cement, wood, steel, gasoline, diesel, explosives, sand and gravel material.

In the calculation of material budget price, you should carefully collect basic information to enable the preparation of the materials budget price in line with reality. Usually the situation according to the project areas where construction materials, external traffic conditions, and have practical experience in construction and related information, according to save money principle, a reasonable choice of supplier sites, the proportion of all goods and materials supply prices, reasonable transport methods. reposted elsewhere in the Research Papers Download http://www.hi138.com aggregate amount of the construction projects big, great impact on project cost, the price should be thorough in the preparation of site investigation, serious collection of geological exploration, testing, design information, to master the production conditions, production processes, transport means, to calculate the correct selection of fixed, to ensure that the aggregate Price correct and reliable.

(B access to the standard rates must be consistent with existing regulations
Different departments in the preparation of budget estimate must be fixed by the respective departments and the existing provisions, the preparation method of budgetary estimate, not mistaken identity.

(C proper use of fixed quotas and subheadings selected
In preparing the project budget, due to the different design stages, also different selection of fixed, fixed at various stages of the case of failure to pay attention to the transition scale factor.

In the selection of the fixed price when the project budget preparation, construction design should be based on the provisions of the construction methods, processes, machinery and equipment configuration, the transport distance, the selected conditions, the fixed line. Meanwhile, to the general description of the scale, chapter explains, section appendix carefully read the instructions and master, familiar with the purpose of each sub-scale the scope of work content and the related use of fixed coefficients.

Since each specific construction project, the actual provisions of the labor situation and the fixed combination of construction measures can not be exactly the same conditions and time scale should be used similar to the provisions of the actual situation, do not allow for modifications and changes in the fixed level. When the fixed large difference between the actual situation and conditions, or fixed missing items, reference should be fixed at close industry sectors to supplement and can not change or changes.

Almost in the use of a fixed budget preparation process, pay close attention to changes in the existing scale and related costs of standards, preparation methods, the required changes, so always use the existing quotas and regulations.

(D engineering calculation
Quantity is one of the main impact of the project cost, engineering calculation was correct or not, will project cost, a great deal of influence economic indicators. Therefore, engineering calculations, design drawings must be in strict accordance with the geometric contours Appendix provides size and stage of the fixed coefficient.

(E scientific and realistic
Professionals in the preparation of budget estimate budget estimate should adhere to the principles of scientific objectivity, in-depth investigation and study, the full collection of first hand to understand the engineering design and construction conditions, the correct application of quotas and the existing provisions, so that the amount of feet, suitable price, costs accurately, and resolutely stop all sorts of excuses and overestimate risk calculation and to engage in "fishing projects" budget. but no less operator counting, want to make enough investment, without leaving gaps.

Third, the conclusion
With the social, economic, and scientific and technological development, cost management of construction projects have entered a new period of comprehensive development and reform, full implementation of building construction project legal person responsibility, the bidding system, construction supervision and contract management system. With the deepening of economic reform and development, preparation of budget estimate methods, content and cost of components vary greatly in recent years, combined with large scale construction projects, involving a wide range of technical complexity, long period, so that construction investment (including estimates estimates, budget) preparation of the task is very heavy. to improve the quality of work budget estimate, the control of project cost is significant.
