Abstract

PURPOSE:To accurately manage a profit in a work section by collating an execution budget with a paid experience and outputting a work profit-loss transient sheet which recognizes a profit-loss condition at an arbitrary time point during works. CONSTITUTION:For the respective types of work items KM, an estimation to indicate costs required for a construction plan and an execution is prepared, an aimed budget which has calculated the budgetary profit at every type of the work item KM is prepared for the estimation, and based on the aimed budget, the execution budget to execute the production plan for the work section is prepared. Further, the execution budget is collated with the paid experience, and the work income transient sheet is outputted which grasps the profit-loss condition at the arbitrary time point during the works. Thus, by outputting the work profit transient sheet at a necessary time, the profit-loss condition at the present time point of the works can be immediately and accurately recognized, and the profit management in the work section can be accurately carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a construction work revenue management system that allows construction work revenue management to be performed at any time even during construction.

(b), Conventional Technology Recently, the content of construction work has become more and more sophisticated and complex, and the cost ratio has also tended to deteriorate.

(C)0 Problems that the invention attempts to solveHowever, in the past,
Because there is no established method to compare budget and actual results,
For process control, construction control, quality control, etc. at the work site, we understand the construction from a technical and construction perspective, compare it with the budget,
It has become impossible to carry out appropriate profit management.

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned drawbacks, it is an object of the present invention to provide a construction work revenue management system that can accurately manage revenue at a construction site.

(d) Means for solving zero problems, that is, the present invention creates an estimate showing the cost required for construction planning and execution for each work type item (KM), and ) Separately, create a target budget (2) that calculates the budget profit, create an execution budget (3) for the workshop to execute the production plan based on the target budget (2), and then create the execution budget (3) based on the target budget (2). It should be configured to output a construction profit/loss transition table (5) that shows the profit and loss status at any point in time during construction by comparing the payment results with 3).

Note that the numbers in parentheses are for convenience and indicate corresponding elements in the drawings, and therefore, this description is not limited to the descriptions on the drawings. The following r (el
The same applies to the column ``Action''.

(e) 0 Effect With the above-described configuration, the present invention can obtain the construction profit and loss status at any given time in the work place by outputting the construction profit and loss transition table (5).

(f), Example Embodiments of the present invention will be described below based on the drawings.

Figure 1 is a flowchart showing an embodiment of the construction revenue management system according to the present invention, Figure 2 is a diagram showing an example of a target budget, Figure 3 is a diagram showing subjects by process, and Figure 4 is an execution budget. FIG. 5 is a diagram showing an example of a construction profit and loss transition table, and FIG. 6 is a diagram showing an example of a breakdown table of the construction profit and loss transition table.

As shown in FIG. 1, the construction work revenue management system SYS according to the present invention, which is executed using a conveter, creates an estimate regarding a certain construction work in step S1.

This estimate takes into account the blueprints, specifications, contract documents, estimate conditions, etc., and also takes into account the various conditions of the work site, creates a construction plan, and calculates the costs required for each type of work. For example, as shown in Figure 3, B's work category 1 is divided into 1 for net construction cost and 2 for expenses. 4, 5 for A building equipment costs, 6 for other construction costs, and 2 for expenses are further divided into 7 for construction costs, and 8 for general expenses. 3 more
For each type of 8, 3 is for temporary construction cost, 9 is for temporary facility cost, 4 is for temporary construction cost KIO, 4 is for building A building cost, and 11 is for pile/earthwork cost.
It is categorized into 12 main subjects, 12 for physical structure, and 13 for finishing costs. Further, each item and major subject are classified into their respective subject KM, and an estimate is prepared for each subject KM mentioned above.

In this way, an estimate is created in step S1 of the construction work revenue management system SYS, and the estimated amount EA is determined. Based on the created estimate, the target budget is prepared in step S2 shown in FIG. is created. The target budget document 2, as shown in Fig. 2, is calculated for each subject KM shown in Fig. 3. This target budget document 2 includes the contents of the estimate,
The budget profit is calculated for each KM item of the type of work based on consideration of design documents, construction plans, etc.

After the target budget 2 has been created, the construction work revenue management system SYS enters step S3 to create an execution budget 3. This is a plan for establishing and implementing production plans regarding quality, construction methods, etc., and enables rational and economical construction management by comparing with actual results.

An example of the output of the execution budget document 3 is shown in Figure 4. In the example shown in FIG. 4, the estimated budget and target budget already obtained in steps S1 and S2 are shown together with the execution budget.

Once the execution budget document 3 has been created, monthly profit management is carried out by comparing the execution budget with the order/payment record, and in order to grasp the final construction profit, step S4 of the construction work revenue management system SYS is performed. , and create Construction Profit and Loss Trend Table 5. This construction profit and loss trend table 5 is
As shown in the figure, a rough calculation for each event or subject is output, and as shown in FIG. 6, a detailed breakdown for each subject is output. In other words, each work site compares the monthly execution budget 6 with actual expenditures 7, and then adds the expected future expenditures 9 to this to determine the final cost FC and final expected profit/loss FB of direct construction costs during the construction period. can be grasped at any point in time. The construction site collects and organizes actual construction costs as construction is carried out, performs cost calculations, and constantly compares construction implementation costs with the budgeted amount. As a result, for the work type KM whose profits and losses are in the red,
Take measures such as improving construction methods, modifying construction plans, and changing designs.

The construction profit and loss trend table 5 is output periodically, such as monthly or weekly, to accurately grasp the profit and loss situation of the construction work.

(g) 0 Effects of the invention As explained above, according to the present invention, each work type subject K
For M, create an estimate showing the cost required for construction planning and execution, create a target budget by calculating the budget profit for each work type item KM based on the estimate, and based on the target budget, the workshop will make a production plan. The system is configured to create an execution budget for carrying out the work, compare the execution budget with the actual payment results, and output the construction profit and loss trend table 5 that shows the profit and loss status at any point during the construction. By outputting the construction profit and loss trend table 5 when necessary, it becomes possible to immediately and accurately grasp the current profit and loss situation of the construction work.
It becomes possible to accurately manage profits at the workplace.
