Description

Technical Field

[0001] The present invention relates to the technical field of engineering management, and in particular to an integrated engineering management system based on engineering cost analysis. Background Art

[0002] In engineering management work, the initial estimated cost of a building often does not match the actual cost. This has brought certain difficulties to our engineering management work. We often need to re-coordinate construction work and material procurement, which is also very unfavorable for cost management and accurate management of working capital.

[0003] In view of this, this application is hereby filed. Summary of the invention

[0004] The purpose of the present invention is to provide an integrated engineering management system based on engineering cost analysis, which can further improve the degree of fit between the initial estimated cost and the actual cost, facilitate more accurate cost management and working capital management, and help managers to predict to a certain extent the situations that may be encountered during the actual construction process, which has positive significance for rationally planning construction work, rationalizing construction expectations, and promoting the smooth progress of the project.

[0005] The embodiment of the present invention is achieved as follows: A comprehensive engineering management system based on engineering cost analysis includes: an engineering cost prediction module and a data correction module.

[0006] The project cost prediction module is used to determine preliminary cost data based on the construction object.

[0007] The data module is used to execute the correction process, which includes the following steps: S1. Determine the construction start time and construction completion time according to the construction plan of the construction object, record the period between the construction start time and construction completion time as the construction time, and record the time required to construct the construction object as the standard construction period.

[0008] S2. Predict the weather forecast data during the construction period based on the historical weather data and real-time weather data of the area where the construction object is located.

[0009] S3. Determine the available construction time within the construction time according to the weather forecast data. If the available construction time is greater than the standard construction period, the construction completion time is corrected forward according to the difference between the available construction time and the standard construction period to obtain a reference early completion time. If the available construction time is equal to the standard construction period, the construction completion time is used as a reference on-schedule completion time. If the available construction time is less than the standard construction period, the construction completion time is corrected backward according to the difference between the available construction time and the standard construction period to obtain a reference delayed completion time.

[0010] S4. If the reference early completion time occurs, the natural loss item in the preliminary cost data is reduced and corrected according to the time difference between the reference early completion time and the construction completion time to obtain the reduced cost data.

[0011] S5. If the reference delayed completion time occurs, the natural loss item in the preliminary cost data is increased and corrected according to the time difference between the reference delayed completion time and the construction completion time to obtain the increased cost data.

[0012] Furthermore, the natural loss item includes at least one of: raw material storage loss, building material natural aging loss and building material mechanical loss.

[0013] Furthermore, if the construction object is located in a Gobi region, the mechanical wear and tear of building materials includes: damage to building materials caused by sand and gravel under the action of wind.

[0014] Furthermore, the correction process includes the following steps: S6. Construct a real-time three-dimensional model of the construction object according to the construction progress.

[0015] S7. When the wind reaches a strength capable of carrying sand and gravel, the wind direction and wind strength are determined based on real-time weather data.

[0016] S8. Determine the windward side of the building based on the wind direction and the real-time three-dimensional model. Determine the impact capacity of gravel on the windward side based on the wind strength, wind direction, angle between the windward side and the material of the windward side. Determine the degree of damage to the windward side based on the impact capacity and duration.

[0017] S9. Increase and amend the natural loss item according to the degree of damage.

[0018] Further, in S8, if the windward surface includes: a first windward surface and a second windward surface, and the first windward surface and the second windward surface are both inclined relative to the wind direction, the first windward surface and the second windward surface are arranged facing each other, and along the wind direction, the distance between the first windward surface and the second windward surface gradually decreases.

[0019] The number of bounces and the intensity of the bounces of gravel between the first windward surface and the second windward surface are determined based on the distance between the first windward surface and the second windward surface, the angular relationship between the first windward surface and the second windward surface and the wind strength, and the degree of damage to the first windward surface and the second windward surface is corrected based on the number of bounces and the bounce impact strength.

[0020] The beneficial effects of the technical solution of the embodiment of the present invention include: The integrated engineering management system based on engineering cost analysis provided by the embodiment of the present invention can further improve the degree of fit between the initial estimated cost and the actual cost, facilitate more accurate cost management and working capital management, and can help managers predict to a certain extent the situations that may be encountered during the actual construction process, which is of positive significance for rationally planning construction work, rationalizing construction expectations, and promoting the smooth progress of the project.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0028] As shown in this specification and claims, unless the context clearly provides an example, the words "a", "an", "the", etc. do not refer to the singular, but also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0029] The flowcharts used in this specification are used to illustrate the operations performed by the system according to the embodiments of this specification. It is understood that the operations of each step are not necessarily performed precisely in order. On the contrary, the steps can be processed in reverse order or simultaneously. At the same time, other operations can also be added to these processes, or one or more operations can be removed from these processes.

[0030] The inventors of the present application have discovered through research that, in actual engineering management work, when the initial estimated cost of a building is inconsistent with the actual cost, some people ignore the actual construction conditions when formulating the initial estimated cost, resulting in a difference between the actual construction progress and the construction plan, which directly leads to major changes in the construction progress and arrangements, and indirectly leads to changes in the cost.

[0031] For the other part, it was not that the initial estimated cost was wrong, but that in the subsequent actual construction process, external conditions (including but not limited to weather conditions) changed significantly, resulting in a deviation between the actual construction conditions and expectations, which led to the situation where the initial estimated cost was inconsistent with the actual cost.

[0032] The above situation is part of the reason why the initial estimated cost is not consistent with the actual cost.

[0033] In order to overcome the deficiencies in the prior art, this embodiment provides an integrated engineering management system based on engineering cost analysis, which includes: an engineering cost prediction module and a data correction module.

[0034] The project cost prediction module is used to determine preliminary cost data based on the construction object. That is, according to the construction scale, materials, construction period arrangement, construction personnel requirements, etc. of the construction object, a series of related cost assessments are performed to obtain preliminary cost data. It should be noted that the confirmation standard of preliminary cost data is not specifically limited in this application and can be formulated according to actual conditions and needs.

[0035] The data module is used to execute the correction process, which includes the following steps: S1. Determine the construction start time and construction completion time according to the construction plan of the construction object, record the period between the construction start time and construction completion time as the construction time, and record the time required to construct the construction object as the standard construction period.

[0036] S2. Predict the weather forecast data during the construction period based on the historical weather data and real-time weather data of the area where the construction object is located.

[0037] S3. Determine the available construction time within the construction period based on weather forecast data, that is, determine the time (working time) during the construction period when construction personnel can normally carry out construction based on weather forecast data and the work and rest schedule of construction personnel, that is, the available construction time.

[0038] The construction time can be divided into the following situations: (1) If the available construction time is greater than the standard construction period, it means that the available construction time is sufficient to complete the construction of the object and there is still time left. In this case, the construction completion time is corrected forward according to the difference between the available construction time and the standard construction period to obtain the reference early completion time. The reference early completion time is the time point obtained by advancing the construction completion time, which represents the time point that may be completed in advance.

[0039] (2) If the construction time is equal to the standard construction period, the construction completion time will be used as the reference on-time completion time. This means that the project can basically be completed on time according to the construction completion time.

[0040] (3) If the available construction time is less than the standard construction period, it means that the available construction time is not enough to complete the construction of the object. In this case, the construction completion time is corrected backwards according to the difference between the available construction time and the standard construction period to obtain the reference delayed completion time. The reference delayed completion time is the time point obtained after postponing the construction completion time, which represents the time point that may delay the construction completion.

[0041] S4. If the reference early completion time occurs, the natural loss items in the preliminary cost data are reduced and corrected according to the time difference between the reference early completion time and the construction completion time to obtain the reduced cost data. Since the actual construction period is shorter than the standard construction period, for items that will have natural loss over time, the natural loss will also decrease as the loss time is shortened due to the shortening of the actual construction time. Therefore, the reduction of the natural loss items can be determined according to the time difference between the reference early completion time and the construction completion time.

[0042] S5. If the reference delayed completion time occurs, the natural loss item in the preliminary cost data is increased and corrected according to the time difference between the reference delayed completion time and the construction completion time to obtain the increased cost data. Since the actual construction period is longer than the standard construction period, for items that will have natural loss over time, the natural loss will increase as the actual construction time increases. Therefore, the increase in the natural loss item can be determined based on the time difference between the reference early completion time and the construction completion time.

[0043] For the preliminary cost data, when determining the extent of reduction and increase of natural loss items, the standards for reduction and increase can be flexibly formulated according to actual needs and circumstances, and this application does not impose specific restrictions.

[0044] Specifically, in this embodiment, the natural loss item includes: at least one of: raw material storage loss, building material natural aging loss and building material mechanical loss loss.

[0045] Among them, if the construction object is located in the Gobi region, that is, the construction environment is the Gobi, the mechanical wear and tear loss of building materials includes: the damage caused to the building materials by sand and gravel under the action of wind.

[0046] Accordingly, the correction process includes the following steps: S6. Construct a real-time 3D model of the construction object according to the construction progress. That is, according to the actual construction situation of the construction object, a 3D model of the current construction object is established. The real-time 3D model will change with the progress of the construction, and it reflects the 3D of the currently constructed part of the construction object.

[0047] S7. When the wind reaches a strength capable of carrying sand and gravel, the wind direction and wind strength are determined based on real-time weather data.

[0048] S8. Determine the windward side of the building based on the wind direction and the real-time 3D model, determine the impact capacity of the gravel on the windward side based on the wind strength, wind direction, angle between the windward side and the material of the windward side, and determine the degree of damage to the windward side based on the impact capacity and duration. That is, determine whether the gravel scratches / collides with the windward side when impacting the windward side.

[0049] S9. Increase and amend the natural loss item according to the degree of damage.

[0050] It should be noted that, in S8, if the windward surface includes: a first windward surface 100 and a second windward surface 200, as Figure 1 As shown, direction K is the wind direction, the first windward surface 100 and the second windward surface 200 are both inclined relative to the wind direction, the first windward surface 100 and the second windward surface 200 are arranged opposite to each other, and along the wind direction, the distance between the first windward surface 100 and the second windward surface 200 gradually decreases.

[0051] At this time, the number of bounces and the intensity of the bounce impact of the gravel between the first windward surface 100 and the second windward surface 200 are confirmed according to the distance between the first windward surface 100 and the second windward surface 200, the angular relationship between the first windward surface 100 and the second windward surface 200 and the wind direction, and the wind strength, and the degree of damage to the first windward surface 100 and the second windward surface 200 is corrected according to the number of bounces and the bounce impact strength.

[0052] Due to the special relationship between the first windward surface 100 and the second windward surface 200 mentioned above, gravel may bounce toward the second windward surface 200 after hitting the first windward surface 100. That is to say, the gravel that has hit the first windward surface 100 will also hit the second windward surface 200. Conversely, the gravel that has hit the second windward surface 200 will also hit the first windward surface 100. This causes the frequency of the first windward surface 100 and the second windward surface 200 being hit by gravel to be higher than that of ordinary windward surfaces. At this time, the degree of damage to the first windward surface 100 and the second windward surface 200 needs to be confirmed in the above manner to avoid inaccurate assessment of the degree of damage.

[0053] Optionally, an integrated engineering management system based on engineering cost analysis can also mark the windward side hit by gravel in the real-time three-dimensional model of the construction object, and at the same time indicate the degree of damage to each windward side, so as to facilitate timely assessment of the actual damage to the construction object, confirm the repair cost, and correct the natural loss items.

[0054] It should be noted that the correction process can be executed before the construction starts or during the construction process, so as to promptly reflect the changing trend of the actual construction cost to the construction party, thereby facilitating the preparation of plans in advance.

[0055] To sum up, the integrated engineering management system based on engineering cost analysis provided by the embodiment of the present invention can further improve the degree of fit between the initial estimated cost and the actual cost, facilitate more accurate cost management and working capital management, and can help managers predict to a certain extent the situations that may be encountered during the actual construction process, which is of positive significance for rationally planning construction work, rationalizing construction expectations, and promoting the smooth progress of the project.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
