I, the main problems and difficulties of cost management
1, the tender offer
How much is the guaranteed cost of the project? How many more points can be reduced? What sub-projects can do unbalanced offer?
2, target cost responsibility system
Target cost subject volume, price, cost how much? Project profitability evaluation? How many points should be submitted? Only to get the correct cost data to ensure that the company, the project department, sub-suppliers multi-win, in order to effectively realize the target cost responsibility system management.
3, the total cost control
Contract signing (subcontracting, resource allocation, etc.): should be based on the cost of the design of the measured value of the volume, price, the completion of the project subcontracting, resource market bidding, purchasing and other contract signing work to ensure that the project contract cost shall not be more than the cost of the design of internal control.
Total cost dynamics: According to the beginning of the budget output value and engineering changes, visas, and the A side of the price of how to get the total dynamic value of the cost of each project? Is the current total input cost exceeded?
4, the process of staging / node control
BIM application scenarios, the completion of the settlement of the cost reduction comparison
Second, the cost of measurement methods
1, the expert method (obsolete)
Starting from the basic structure of the budget, the establishment of the enterprise through the quota and the actual comparison of the quota library, as a cost measurement of the basic model. Through the decomposition of the budget (WBS), more away from the actual, and then the budget value and the actual comparison, the budget plan value and the actual comparison, the cost control variables are too fine, its unit price parameters for the fictitious, the market does not exist, so the overall accuracy is low, the results are sloppy, and the actual interface can not be achieved even if the cost is huge.
2, large indicator estimation
Can avoid the actual control of the project in the project cost project measurement problems, but the cost control variables are too loose, the basic actual control of the cost of the subject of the project volume do not know, low precision.
3, the industry's excellent elite method (to simplify the complex problem)
Merge the budget to establish the engineering cost subjects - and the actual data can interface, as shown below.
Through the above method can be a complex problem simplified, solve the main contradiction principle, and the market can interface (market unit price can be measured).
The cost account consists of two parts: the cost classification account and the minimum cost control account. One of the cost control subjects that is the basic control variables of the system, the system can be refined to its measurement, contract signing, the corresponding dynamic control of all operations, the following chart.
Indicator cloud platform - can be completed through the software to compare the construction drawings and construction budgets of the enterprise cost project, the working principle schematic and flow charts are shown below.
Third, engineering cost data accumulation and analysis indicators cloud platform Main features and technical advantages
1, rapid technical measures
Budget list with material consumption of a variety of format files complete automatic import.
Initial templates for enterprise inventory projects and the creation of their project budget guidelines.
Intelligent automatic creation of enterprise list items.
2. Accuracy technical measures
Automatic detection of the budget list import function to ensure that the budget data correctly into the system.
The automatic detection of the value of the consolidated budget to ensure the correctness of the construction plan budget, etc..
3. Integrity of technical measures
Each data of construction projects in the software includes: construction drawings budget and construction budget part.
Indicator + content in hundred dollars + cost reduction % + volume difference contribution % + price difference contribution %.
Cost accounts are generated through system templates, effectively preventing omissions.
4, normative technical measures
The establishment of enterprise engineering cost items are generated through the system template, laying a unified foundation for the comparison of different projects.
The enterprise calculation parameters are gradually standardized.
Cost items are generated through system templates, resulting in standardized form, name, and content.
5, unified management of budget and enterprise cost data
This software system is based on multi-project architecture, is different from the traditional budget software is the most important thing, so the system has a strong budget and construction budget management functions.
Through the engineering cost big data network I give you to analyze the cost measurement of some of the problems and solutions, I believe we have a deeper understanding of the construction industry professionals interested in, welcome to do further understanding or leave a message to consult.
