Description

Technical Field

[0001] The present invention relates to the technical field of construction management, and in particular to a road construction management platform and method based on 3DGIS+BIM. Background Art

[0002] The field of construction management technology focuses on the use of scientific management principles and advanced technical methods to improve the efficiency and quality of construction projects. The field integrates project management, resource optimization, cost control, quality assurance, time management and other aspects. With the advancement of technology, tools including computer-aided design (CAD) and building information modeling (BIM) technology are widely used in construction management, helping project managers to plan, monitor, and adjust construction activities more accurately to ensure that projects are completed on time and on budget. Construction management also involves environmental impact assessment, safety management and compliance review to ensure that the construction process complies with regulatory requirements and minimizes negative impacts on the environment.

[0003] Among them, the road construction management platform is an information platform designed specifically for road construction and maintenance projects. It integrates a variety of technologies and tools, such as GIS (geographic information platform), BIM (building information modeling) and project management software, to assist project teams in effectively managing road construction projects. The main purpose of this type of platform is to provide a real-time, interactive environment that allows project managers to track project progress, analyze resource allocation, predict project risks, and provide decision support. By using such a platform, construction teams can coordinate work more effectively, optimize construction plans, reduce delays, and improve the quality and safety of the overall project.

[0004] Although the existing road construction management platform integrates advanced tools such as CAD and BIM, common problems in actual operation include untimely information updates, inaccurate risk assessments, and inefficient resource allocation. For example, traditional construction management methods often rely on periodic reports and plan reviews. This intermittent information flow method can easily lead to delays in project monitoring, thereby affecting the construction progress and the timeliness of resource allocation. In terms of risk management, due to the lack of real-time data support, traditional methods cannot accurately predict and respond to risks caused by changes in the environment and emergencies, which increases safety hazards and unforeseen costs. Resource allocation is based on experience and static plans, lacking adaptability to real-time scenarios and changing conditions, which not only reduces resource utilization efficiency, but also misses the best construction time due to slow response, which will eventually lead to project delays, increased costs, and difficulty in ensuring construction quality, bringing many challenges to construction management. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and propose a road construction management platform and method based on 3DGIS+BIM.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions: The road construction management platform based on 3DGIS+BIM includes:

[0007] The construction sequence optimization module initializes multiple location markers based on 3DGIS and BIM data, performs path search, updates terrain and building model information, adjusts the construction sequence, and generates a construction sequence optimization plan;

[0008] The construction risk management module uses the BIM model to analyze the building structure risk according to the construction sequence optimization plan, obtains the risk assessment framework, monitors the construction risk according to the risk assessment framework, updates the risk management dynamics, combines the environmental changes monitored by 3DGIS and makes risk management adjustments, and generates a real-time risk adjustment strategy;

[0009] The resource allocation and efficiency module uses the real-time risk adjustment strategy to allocate resources, dynamically allocates manpower and materials according to construction needs and risk assessment, analyzes resource distribution and utilization, obtains adjusted resource allocation efficiency results, and uses 3DGIS spatial analysis and BIM to optimize resource allocation and obtain optimized resource allocation solutions;

[0010] The construction progress adjustment module is based on the optimized resource allocation plan, uses 3DGIS and BIM technology, analyzes the deviation of the planned progress, makes real-time adjustments, and generates progress synchronization results. Based on the progress synchronization results, according to the real-time situation and environmental data of the construction site, combined with the updated information of the BIM model, the progress is adjusted to generate an adjusted construction schedule.

[0011] As a further solution of the present invention, the steps for obtaining the construction sequence optimization solution are specifically as follows:

[0012] Based on 3DGIS and BIM data, terrain and building information are extracted from 3DGIS and BIM data sets, and the location marker set is initialized through the formula:

[0013]

[0014] Calculate the weighted score of each location tag to obtain the location tag weighted score set, where P a Representative location marker weighted score, D a,i represents the information of the i-th location mark, W a,i represents the weight coefficient of the i-th place marker, and n represents the total number of place markers;

[0015] Using the set of weighted scores of place markers, path optimization is performed, applying the formula:

[0016]

[0017] Calculate the path optimization score set, where R a represents the path optimization score, P a,i represents the weighted score of the i-th location marker;

[0018] The construction sequence is adjusted by applying the path optimization score set, using the formula:

[0019]

[0020] Calculate the adjusted construction sequence score and establish a construction sequence optimization plan, where S a represents the adjusted construction sequence score, R a Represents the path optimization score.

[0021] As a further solution of the present invention, the steps of obtaining the risk assessment framework are specifically as follows:

[0022] According to the construction sequence optimization scheme, the building component data extracted from the BIM model, including the compressive strength and bending performance of each component, are used through the formula:

[0023]

[0024] Strengthen the influence of material properties on risk assessment, evaluate structural risk, and obtain a set of structural risk indices, where R b represents the set of structural risk indices, S b,j represents the compressive strength of the jth component, L b,j represents the bending performance of the jth component, n b Indicates the total number of components;

[0025] By analyzing the structural risk index set, the formula is:

[0026]

[0027] Balance and improve the sensitivity of risk assessment, calculate the weighted risk index, and obtain the overall risk level of the building structure, where F b represents the weighted risk index, R b,j is the set of structural risk indices for the jth component;

[0028] Based on the overall risk level of the building structure, combined with the building's usage and historical safety data, the formula is used:

[0029]

[0030] Form a risk assessment framework, in which E b Represents the risk assessment framework score, F bis the weighted risk index, U b represents the risk weighting factor of the building use, H b Adjust factor for historical safety record.

[0031] As a further solution of the present invention, the step of obtaining the real-time risk adjustment strategy is specifically:

[0032] According to the risk assessment framework, the safety detection data of the construction site, including vibration level and noise data, are captured from the real-time monitoring configuration. The data is obtained through vibration sensors installed at the construction site, using the formula:

[0033]

[0034] Enhance the sensitivity to abnormal data and generate risk assessment scores, where V c,x and N c,x Represent the vibration and noise level data of the xth monitoring point, respectively, where R c represents the risk assessment score, n c Indicates the total number of monitoring points;

[0035] Compare the risk assessment score to historical risk data using the formula:

[0036]

[0037] Calculate the adjusted average risk index, where A c represents the average risk index after adjustment, R c,x The risk assessment score for the xth monitoring point;

[0038] According to the adjusted average risk index and the environmental change data monitored by real-time 3DGIS, the formula is used:

[0039]

[0040] Incorporate environmental change factors into the calculation, adjust the risk index, and generate a real-time risk adjustment strategy, where S c stands for real-time risk adjustment strategy, A c is the adjusted risk index, E c and T c They represent the impact coefficient and safety threshold of environmental changes respectively.

[0041] As a further solution of the present invention, the steps for obtaining the adjusted resource allocation efficiency result are specifically as follows:

[0042] Based on the real-time risk adjustment strategy, the initial demand for human and material resources is quantified, and the resource demand is adjusted according to the project stage and the predicted risk level, using the formula:

[0043] D d =(P d ×C d )+(Q d ×M d )

[0044] Get the total resource demand cost, where D d represents the total resource demand cost, P d and Q d Represents the demand for manpower and materials, C d and M d represents the corresponding unit cost;

[0045] Based on the total resource demand cost, matching and optimization are performed in combination with real-time available resources using the formula:

[0046]

[0047] The resource matching efficiency is obtained by calculating the difference ratio between resource requirements and available resources, where E d represents resource matching efficiency, R d Represents the total cost of available resources, D d represents the total resource requirement cost;

[0048] Compare the resource matching efficiency with historical efficiency data using the formula:

[0049] S d =E d ×log(1+H d / L d )

[0050] Generate the adjusted resource allocation efficiency results, where H d represents the resource allocation efficiency in the same period of history, L d Indicates the lowest efficiency in history, S d represents the adjusted resource allocation efficiency result, E d To match resources efficiently.

[0051] As a further solution of the present invention, the step of obtaining the optimized resource allocation solution is specifically as follows:

[0052] The resource allocation efficiency results after the adjustment are analyzed, and the current resource distribution is spatially analyzed using 3DGIS technology. The formula is:

[0053]

[0054] By calculating the overall resource allocation effect through spatial weighting, the spatial weighted resource allocation effect is generated, where sh,z Represents the spatial coordinate coefficient of the z-th resource point, u h,z Indicates the resource amount of the zth resource point, v h,z The resource utilization rate of the z-th resource point, R h represents the spatially weighted resource allocation effect, n h Indicates the total resource points;

[0055] By using the resource allocation effect of spatial weighting, BIM technology is applied to optimize resource allocation in a gradient manner, using the formula:

[0056]

[0057] Get resource utilization, where E h represents resource utilization, k h,i represents the expected resource volume after optimization of the zth resource point, u h,i is the original resource amount of the zth resource point;

[0058] Compare the resource utilization with the real-time situation on site, using the formula:

[0059]

[0060] Get the optimal resource allocation plan, where S h represents the optimal resource allocation plan, E h is the resource utilization rate, T h To configure the threshold.

[0061] As a further solution of the present invention, the steps for obtaining the adjusted construction schedule are specifically as follows:

[0062] Based on the optimized resource allocation scheme, a 3DGIS spatial analysis is performed on the current construction progress to quantify the deviation between the plan and the real-time plan. The formula is:

[0063]

[0064] By referring to the spatial sensitivity, the accuracy of deviation analysis is enhanced to obtain the progress deviation analysis results, where a g and b g Represents real-time progress and planned progress respectively, d g is the spatial sensitivity coefficient, P g Indicates the results of the schedule deviation analysis;

[0065] According to the progress deviation analysis results, the construction plan is adjusted using BIM technology, using the formula:

[0066]

[0067] Get the weighted progress synchronization result, where w g Represents the workload weight of multiple construction sites, Q g Represents the weighted progress synchronization result, a g 、b g Indicates real-time and planned progress;

[0068] Based on the weighted progress synchronization results, combined with real-time construction site, environmental data and BIM model update information, and adjusted, the formula is:

[0069]

[0070] Generate an adjusted construction schedule, where m g represents the environmental adaptability adjustment coefficient, n g is the efficiency benchmark value, R g represents the adjusted construction schedule, Q g Synchronize results for progress.

[0071] The road construction management method based on 3DGIS+BIM is implemented based on the above-mentioned road construction management platform based on 3DGIS+BIM, and includes the following steps:

[0072] S1: Based on 3DGIS and BIM data, initialize geographic tags, search for paths according to terrain and building features, adjust construction paths based on terrain changes and building data, match field conditions, optimize paths and match construction needs, and obtain construction path plans;

[0073] S2: Through the construction path plan, use the BIM model to conduct risk analysis on the building structure, evaluate the risk points of key structures, identify potential risk areas, update and optimize risk management strategies, and generate a risk assessment framework;

[0074] S3: Based on the risk assessment framework, combined with 3DGIS real-time data, adjust the risk management strategy, respond to environmental changes and project demand updates, use dynamic management methods to optimize risk response, and create a real-time risk response strategy;

[0075] S4: Utilize the real-time risk response strategy to dynamically allocate human and material resources, allocate resources according to risk assessment and construction progress, optimize resource allocation in combination with 3DGIS spatial analysis, and generate a resource allocation plan;

[0076] S5: Based on the resource allocation plan, use 3DGIS and BIM technology to monitor the construction progress in real time, compare the plan with the real-time progress, adjust the construction plan and match the real-time changes, update the progress plan, and establish an adjusted construction progress plan.

[0077] Compared with the prior art, the advantages and positive effects of the present invention are:

[0078] In the present invention, by adopting the deep integration of 3DGIS and BIM data, through the initialization of the location marker and the path search, not only the real-time update of the terrain and building model information is realized, but also the construction sequence is accurately adjusted. This strategy improves the adaptability and accuracy of the construction plan, including in complex geographical environments, and can effectively avoid the construction errors and delays caused by information lag in conventional methods. Through the dynamic analysis of the risk of the building structure by the BIM model, combined with the environmental changes monitored by 3DGIS, the real-time monitoring and adjustment of the construction risk are realized, and the accuracy and real-time performance of risk management are significantly enhanced, which helps to respond to emergencies in a timely manner and reduce potential safety accidents and cost overruns. In terms of resource allocation, through spatial analysis and resource utilization analysis, the allocation of manpower and materials is optimized, which not only improves the efficiency of resource use, but also ensures the quality and speed of construction. Through real-time progress monitoring and dynamic updating of BIM model information, the adjusted construction schedule is more accurate, effectively synchronizing the actual situation on site with the planned goals, thereby improving the overall execution efficiency and success rate of the project.

[0112] Calculate P a :

[0113] P a =100×0.9 2 +150×0.7 2 +120×0.5 2

[0212] D d =(P d ×C d )+(Q d ×M d )

[0213] P d : The number of workers is determined based on the scale of the current construction project and risk assessment, setting the current project to require 50 workers;

[0214] C d : The unit cost per person depends on the worker's skill level and regional wage standards. The average cost per person is set at $200 / day;

[0215] Q d : Material demand, based on the design and construction phase plan of the construction project, is predicted to require 1,000 units of material;

[0216] M d : Material unit cost, based on market price and supply conditions, set the material cost per unit to $15;

[0217] Calculate D d :

[0218] D d =(50×200)+(1000×15)

[0219] D d =10000+15000=25000

[0220] Total resource requirement cost D d = $25,000, which reflects the total cost given the current risk assessment strategy and project requirements.

[0221] The formula for resource matching efficiency is:

[0222]

[0223] R d : The total cost of available resources, provided by the finance department based on the budget and resource management system, is set to $300,000;

[0224] D d : The total demand cost calculated from the previous step;

[0225] Calculate E d :

[0226]

[0227] E d =0.8333

[0228] Resource allocation efficiency d =83.33%, showing the matching degree between current resource configuration and actual available resources.

[0229] The formula for the adjusted resource allocation efficiency result is:

[0230] S d =E d ×log(1+H d / L d )

[0231] E d : The resource allocation efficiency calculated from the previous step;

[0232] H d : The resource allocation efficiency in the same period in history is obtained from the historical data management system and is set to 85%;

[0233] L d : The historical minimum efficiency, also obtained from historical records, is set to 75%;

[0234] Calculate S d :

[0235] S d =0.8333×log(1+0.85 / 0.75)

[0236] S d =0.8333×log(1+1.1333)

[0237] S d =0.8333×0.1222=0.1018

[0238] Adjusted resource allocation efficiency result S d =10.18%, which reflects the adjustment impact of historical data on the current resource allocation efficiency.

[0239] See also Figure 6 , the specific steps for obtaining the optimized resource allocation plan are:

[0240] Analyze the adjusted resource allocation efficiency results, use 3DGIS technology to perform spatial analysis on the current resource distribution, and use the formula:

[0241]

[0242] By calculating the overall resource allocation effect through spatial weighting, the spatial weighted resource allocation effect is generated, where s h,z Represents the spatial coordinate coefficient of the z-th resource point, u h,z Indicates the resource amount of the zth resource point, v h,z The resource utilization rate of the z-th resource point, R h represents the spatially weighted resource allocation effect, n h Indicates the total resource points;

[0243] By utilizing the spatial weighted resource allocation effect, BIM technology is applied to optimize resource allocation in a gradient manner, using the formula:

[0244]

[0245] Get resource utilization, where E h represents resource utilization, k h,i represents the expected resource volume after optimization of the zth resource point, u h,i is the original resource amount of the zth resource point;

[0246] Compare resource utilization with the real-time situation on site, using the formula:

[0247]

[0248] Get the optimal resource allocation plan, where S h represents the optimal resource allocation plan, E h is the resource utilization rate, T h To configure the threshold.

[0249] The formula for spatially weighted resource allocation effect is:

[0250]

[0251] s h,z : The spatial coordinate coefficient of the z-th resource point, representing the spatial weight of the resource location in the 3DGIS system, for example, obtained by quantitative calculation through the GIS system, and set to 0.8, 0.9, and 0.85 respectively;

[0252] u h,z : The resource quantity of the zth resource point is obtained through real-time monitoring of the resource management system, for example, 100, 150, 120 units;

[0253] v h,z : Resource utilization rate of the zth resource point;

[0254] Set up 3 resource points and calculate R h :

[0255] Rh =(0.8×100×0.75)+(0.9×150×0.60)+(0.85×120×0.80)

[0256] R h =(60)+(81)+(81.6)=22

[0257] The obtained R h =222.6 indicates the total effect of resource allocation based on spatial weight considerations, showing the comprehensive effect of resource utilization after considering spatial distribution.

[0258] Resource utilization formula:

[0259]

[0260] k h,z : The expected resource volume of each resource point after BIM optimization, obtained through the analysis of the BIM model, for example, the expected volume is 110, 140, and 130 units respectively;

[0261] u h,z : The actual amount of resources mentioned in the previous step;

[0262] Calculate E h :

[0263]

[0264] E h =1-0.0789=0.9211

[0265] The calculated E h =0.9211 indicates the efficiency of resource allocation after optimization. A higher value shows that the optimization measures have improved the efficiency of resource utilization.

[0266] The formula for optimizing resource allocation plan:

[0267]

[0268] E h : The optimized efficiency calculated from the previous step;

[0269] T h : The actual executable resource allocation threshold is set by the project management team based on project requirements and resource conditions, for example, 0.9;

[0270] Calculate S h :

[0271]

[0272] S h=(1.0234) 1 / 2 =1.0116

[0273] The final S h =1.0116 represents the effect of the resource allocation plan after optimization and adjustment based on the actual on-site conditions. A value exceeding 1 indicates that the effectiveness of the plan is higher than the predetermined threshold, indicating that the resource allocation is extremely effective.

[0274] See also Figure 7 , the specific steps for obtaining the adjusted construction schedule are:

[0275] Based on the optimized resource allocation plan, 3DGIS spatial analysis is performed on the current construction progress to quantify the deviation between the plan and the real-time plan. The formula is:

[0276]

[0277] By referring to the spatial sensitivity, the accuracy of deviation analysis is enhanced to obtain the progress deviation analysis results, where a g and b g Represents real-time progress and planned progress respectively, d g is the spatial sensitivity coefficient, P g Indicates the results of the schedule deviation analysis;

[0278] According to the progress deviation analysis results, use BIM technology to adjust the construction plan through the formula:

[0279]

[0280] Get the weighted progress synchronization result, where w g Represents the workload weight of multiple construction sites, Q g Represents the weighted progress synchronization result, a g 、b g Indicates real-time and planned progress;

[0281] Based on the weighted progress synchronization results, combined with real-time construction site, environmental data and BIM model update information, and adjusted, the formula is:

[0282]

[0283] Generate an adjusted construction schedule, where m g represents the environmental adaptability adjustment coefficient, n g is the efficiency benchmark value, R g represents the adjusted construction schedule, Q g Synchronize results for progress.

[0284] Schedule deviation analysis result formula:

[0285]

[0286] d g : The spatial sensitivity coefficient of each construction point is obtained by 3DGIS analysis and is calculated based on the complexity of the geographical location and construction environment, for example: 0.9, 1.0, 0.95;

[0287] a g : Actual progress, obtained through real-time monitoring of the construction management system, for example: 70%, 80%, 75%;

[0288] b g : Planned progress, set according to the project management plan, for example: 75%, 85%, 80%;

[0289] Set three construction points and calculate P g :

[0290]

[0291] P g =(0.9 0.0667)+(1.0 0.0588)+(0.95 0.0625)

[0292] P g =0.0600+0.0588+0.0594=0.1782

[0293] Score P g =0.1782 represents the total deviation rate of the construction progress. A lower value shows a smaller deviation, indicating that the actual progress is relatively close to the planned progress.

[0294] The formula for weighted progress synchronization results is:

[0295]

[0296] w g : Workload weight, which is allocated according to the workload and importance of each construction site, for example: 1.5, 2.0, 1.8;

[0297] a g 、b g : The aforementioned actual and planned progress;

[0298] Calculate Q g :

[0299]

[0300] Calculated Q g =0.9684 represents the weighted progress synchronization result, and being close to 1 indicates that the adjusted progress is very close to the plan.

[0301] Formula for the adjusted construction schedule:

[0302]

[0303] Q g : The result obtained from the previous step;

[0304] m g : Environmental adaptability adjustment coefficient, which takes into account environmental variables such as weather or supply chain impact, is set to 1.05;

[0305] n g : The efficiency benchmark value is the target value set based on historical data and engineering standards and is set to 1.00;

[0306] Calculate R g :

[0307]

[0308] R g =(1.0168) 1 / 3 =1.0056

[0309] The obtained R g =1.0056 indicates that the adjusted construction schedule is slightly improved compared with the target schedule, reflecting the effectiveness of the optimization measures and their adaptability to practical applications.
