Abstract: With the continuous development of the construction industry, cost control during the construction phase of engineering projects has attracted more and more attention. Due to limitations such as information isolation and low processing efficiency, traditional cost control methods can no longer meet the high requirements for cost control in modern engineering projects. The emergence of Building Information Modeling (BIM) technology provides new solutions for dynamic cost control during the construction phase of engineering projects. Based on this, this article discusses in detail the dynamic control of costs during the construction phase of engineering projects based on BIM, with a view to providing useful reference for practice and research in related fields.
Keywords: BIM technology; project construction; cost control
BIM technology realizes the integration and sharing of information at all stages of engineering projects by building three-dimensional digital models, providing more accurate and timely data support for cost control. During the construction stage, BIM-based dynamic cost control can improve the accuracy and efficiency of cost control, optimize the cost control process, enhance the cost control awareness of all participants, and realize the dynamic correlation between cost control and construction progress.
1 Problems existing in the dynamic control of costs during the construction phase of engineering projects
1.1 Imperfect cost control system
During the construction phase of engineering projects, the improvement of the cost control system is directly related to the effectiveness of cost control. However, the current cost control systems of many engineering projects during the construction phase have many imperfections. First, the cost control objectives are unclear. Some engineering projects lack clear cost control objectives during the construction stage, causing cost control work to lose direction. This makes it impossible for all parties involved to form a unified awareness of cost control and to effectively carry out cost control work. Second, cost control responsibilities are not implemented. During the construction phase of a project, cost control responsibilities should be clarified to each participant to form an effective responsibility network. However, some engineering projects often have unclear responsibilities and buck-passing during the construction process, resulting in the inability to effectively implement cost control. Third, the cost control process is not standardized. Standardized processes are an important guarantee to ensure that cost control work is carried out in an orderly manner. However, there are many irregularities in the cost control process during the construction phase of some engineering projects, such as cumbersome processes and missing links. These problems not only affect the efficiency of cost control work, but also increase the difficulty of cost control.
1.2 Lack of cost control methods
With the continuous development of science and technology, cost control methods during the construction phase of engineering projects also need to be continuously updated and improved. However, some current engineering projects still use traditional cost control methods during the construction phase, such as manual statistics, manual calculations, etc., which are inefficient and cannot meet the requirements of modern engineering projects for cost control accuracy and efficiency. First, the traditional cost control method mainly relies on manual data collection and processing, which is heavy workload and error-prone; second, the data is not updated in a timely manner, resulting in lagging cost control information and unable to provide effective support for decision-making; third, the lack of full-process and all-round cost monitoring of the project can easily lead to cost overruns and waste. Therefore, how to update cost control methods and introduce advanced technologies and means is one of the issues that needs to be solved urgently in the dynamic cost control during the construction phase of current engineering projects.
1.3 Lack of awareness of cost control
The strength of cost control awareness directly affects the implementation of cost control work. At present, some project managers and construction personnel have insufficient understanding of the importance of cost control and lack of initiative and enthusiasm for cost control, resulting in frequent material waste, labor overtime, etc. during the construction process, increasing unnecessary expenditures. The weak awareness of cost control is mainly reflected in the following aspects: 1. Managers have insufficient understanding of the importance of cost control and lack an overall concept and long-term vision; 2. Construction workers lack awareness of saving and cost and waste materials and labor at will during the construction process; 3. There is a lack of communication and collaboration among all participants, and they are unable to form a unified awareness and action of cost control. The existence of these problems prevents cost control from being effectively implemented and increases the cost risk of the project.
1.4 Cost control is out of touch with construction progress
During the construction phase of an engineering project, cost control is closely linked to construction progress. Some engineering projects ignore the correlation between the two during the construction process, resulting in a disconnect between cost control work and construction progress. This will not only affect the smooth progress of the construction progress, but also increase additional costs and reduce the overall benefits of the engineering project. The disconnect between cost control and construction progress is mainly manifested in the following aspects: 1. The lack of a unified cost control and construction progress management platform results in the inability to share and update information in real time between the two. 2. Managers often only focus on construction progress and ignore cost control, resulting in actual costs exceeding the budget. 3. Problems such as design changes and untimely material supply often occur during the construction process, causing construction progress to be hindered and additional costs added.
2 Advantages of dynamic cost control during the construction phase of engineering projects based on BIM
2.1 Improve cost control accuracy
BIM technology can achieve refined management during the construction phase of engineering projects by constructing three-dimensional digital models. In terms of cost control, the introduction of BIM technology can greatly improve the accuracy of cost control. The BIM model can accurately calculate key data such as project quantities, material usage, and labor hours, avoiding errors and omissions in traditional manual statistics and manual calculations. At the same time, BIM technology can also update data in real time to ensure the accuracy and timeliness of cost control information. This helps managers more accurately grasp cost dynamics during the construction process and provides strong support for decision-making.
2.2 Optimize cost control process
BIM technology has powerful information integration and collaborative working capabilities, which can optimize the cost control process during the construction phase of engineering projects. Through the BIM platform, all participants can share cost control information in real time, strengthen communication and collaboration, and reduce information islands and duplication of work. This can not only improve the efficiency and quality of cost control work, but also reduce cost risks during the construction phase of engineering projects. At the same time, BIM technology can also realize the automation and intelligence of the cost control process, further reducing the workload of managers and improving the efficiency and accuracy of cost control work.
2.3 Enhance cost control awareness
The visualization characteristics of BIM technology can help engineering project managers and construction personnel better understand the importance of cost control. Through the BIM model, the cost changes during the construction process can be visually viewed, and cost control problems can be discovered and solved in a timely manner. This intuitive and visual management method can enhance the cost control awareness of all participants and improve the initiative and enthusiasm for cost control. At the same time, BIM technology can also provide rich cost control data and reports to help managers more comprehensively understand the cost situation during the construction process and provide strong support for cost control decisions.
2.4 Realize the dynamic correlation between cost control and construction progress
Usually, material cost accounts for about 60% of the finished product consumption cost. Controlling material cost is mainly to control the usage quantity of construction consumption. By introducing BIM technology, the entire production process can be simulated in advance, the design and construction plans can be optimized, and the construction process can be dynamically fed back, thereby continuously updating the optimal solution for consumption. BIM technology can realize the dynamic correlation between cost control and construction progress during the construction phase of engineering projects. Through the BIM platform, managers can monitor construction progress and cost changes in real time, and adjust construction plans and cost control strategies in a timely manner. This helps ensure the smooth progress of the construction progress, avoid additional cost expenditures, and improve the overall efficiency of the project.
In addition, BIM technology can also realize intelligent prediction and analysis of construction progress and cost control, help managers discover potential cost risks and schedule problems in advance, and provide strong support for timely response measures. The dynamically related management method can ensure that cost control and construction progress during the construction process are always coordinated, thereby achieving overall optimization and maximizing benefits during the construction phase of the project.
3 BIM-based dynamic control strategy for cost during the construction phase of engineering projects
3.1 Establish a BIM-based cost control system
During the construction phase of engineering projects, it is crucial to establish a BIM-based cost control system. This is not only the basis for cost control work, but also the key to ensuring the smooth progress of the project and maximizing benefits.
1) The cost control system should clearly define the cost control objectives. These goals should be both specific and feasible, and can guide cost control efforts throughout the construction phase. Through BIM technology, project costs can be analyzed in detail, thereby formulating more accurate and reasonable cost control targets.
2) The cost control system needs to implement cost control responsibilities. Each participant should clarify their responsibilities and tasks in cost control and form an effective cost control responsibility network. The BIM platform can provide real-time cost control information, help all participants better perform their responsibilities, and achieve comprehensive coverage of cost control.
3) The cost control system should standardize the cost control process. Through BIM technology, the cost control process can be optimized and unnecessary links and duplication of work can be reduced. All participants can work collaboratively on the BIM platform to realize real-time sharing and updating of cost control information, improving the efficiency and quality of cost control work.
3.2 Adopt advanced cost control methods
In the cost control during the construction phase of engineering projects based on BIM, the use of advanced cost control methods is the key to improving the cost control effect.
1) BIM models can be used for automatic statistics of project quantities and accurate calculation of material usage. By building a three-dimensional digital model, BIM technology can accurately calculate the engineering quantities and material usage of each component, avoiding errors and omissions in traditional manual statistics and manual calculations. This can not only improve the accuracy of cost control, but also reduce unnecessary cost expenditures.
2) BIM technology can be used for construction progress simulation and cost prediction analysis. By simulating construction progress, cost needs and changes at different construction stages can be predicted, thereby formulating a more reasonable cost control strategy. This helps to identify potential cost risks in advance and take corresponding countermeasures to ensure that cost control during the construction phase is always under control.
3) BIM technology can also be used for dynamic cost analysis and optimization. During the construction process, actual costs often deviate from budgeted costs. Through the cost dynamic analysis function of BIM technology, cost changes can be monitored in real time, the causes of deviations can be found and corresponding corrective measures can be taken. This helps keep actual costs within budget and ensures the economic benefits of the project.
3.3 Strengthen cost control awareness training and assessment
Enhancing the cost control awareness of project managers and construction personnel is an important prerequisite to ensure the effective implementation of cost control work. At the same time, this part is also the weakest link in enterprise management.
In view of this situation, it is crucial to strengthen cost control awareness training. First, strengthen cost control publicity. Strengthen publicity and education on the cost control awareness of participants, cultivate the cost control awareness of all employees, and introduce strategic cost management ideas to guide each participant to understand that cost control is an important strategic factor related to the multi-faceted market competition of their enterprises. Second, corresponding incentive mechanisms and assessment mechanisms should be established. By setting up cost control incentives and penalties, all participants are encouraged to actively participate in cost control work and achieve good results. At the same time, cost control work is linked to personal performance and promotion to enhance the sense of responsibility and initiative of all parties involved. This helps to create a good atmosphere of full participation and joint advancement, and improves the execution and effectiveness of cost control work.
3.4 Realize cost control and real-time monitoring of construction progress
During the construction phase of an engineering project, realizing cost control and real-time monitoring of construction progress is the key to ensuring the smooth progress of the project. BIM technology focuses on the assistance of modern technology. The BIM cost management platform realizes real-time monitoring of costs through the association of cost data with models and progress information. Combined with the platform's built-in early warning process, it can help managers analyze and resolve deviations in a timely manner to ensure the achievement of goals.
1) Use the BIM platform to monitor construction progress in real time. By comparing the actual construction progress with the planned construction progress, progress deviations can be discovered in a timely manner and corresponding adjustment measures can be taken. This helps ensure construction progresses as planned and avoids delays and additional costs.
2) Use the BIM platform to monitor cost changes in real time. Collect the physical information of the project into the BIM system, use its calculation and analysis functions to obtain the data difference between the actual construction cost and the planned cost in a timely manner, and accurately grasp the cost dynamics during the construction process by updating the cost data in the BIM model in real time. When the actual cost exceeds the budget, measures can be quickly taken to adjust and optimize to ensure that the cost is controlled within a reasonable range.
3) To achieve cost control and real-time monitoring of construction progress, it is necessary to strengthen communication and collaboration among all parties involved. Through the real-time sharing function of the BIM platform, all parties involved can learn about construction progress and cost changes in a timely manner, discuss solutions together, and advance the work collaboratively. Supervisors conduct project reviews on the platform, owners conduct project progress inspections on the platform, and contractors communicate with subcontractors and suppliers on the platform in a timely and effective manner. The BIM information management platform, lightweight BIM models, and mobile clients are used to achieve mobile office, seamless browsing of on-site construction pictures, and timely communication among all participants during production, so that the plan is issued in a reasonable and timely manner. BIM allows all parties involved to improve work efficiency while also avoiding cost increases caused by information lag. This helps to form a teamwork model with close coordination and efficient operation, and improves the overall efficiency of the construction phase of the project.
3.5 Continuously optimize cost control strategies
In the process of dynamic cost control based on BIM during the construction phase of engineering projects, optimizing cost control strategies is an important way to improve the level of cost control.
1) Cost control strategies should be continuously adjusted and improved based on the actual conditions and problems during the construction process. For example, when encountering unforeseen factors such as material price increases and design changes, cost control strategies should be adjusted in a timely manner to cope with these changes. Therefore, by flexibly adjusting cost control strategies, we can better adapt to various changes and challenges during the construction process.
2) Cost control work should be summarized and evaluated regularly. By comparing and analyzing the difference between actual costs and budgeted costs, as well as the implementation effect of cost control strategies, we can identify existing problems and deficiencies in cost control work. Develop corresponding improvement measures and implement them in response to these problems and shortcomings, and continuously improve the quality and level of cost control work.
3) The continuous optimization of cost control strategies should be regarded as a long-term task. With the continuous advancement of science and technology and increasingly fierce market competition, cost control during the construction phase of engineering projects is facing more and more challenges and requirements. Therefore, all participants should always pay attention to and attach importance to cost control work, actively explore and apply new cost control methods and technical means, and continuously improve their cost control capabilities and competitiveness. By continuously optimizing cost control strategies, we can continuously improve the cost control level during the construction phase of engineering projects, reduce project cost risks, improve overall project benefits, and lay a solid foundation for the sustainable development of enterprises.
4 Conclusion
BIM-based dynamic cost control during the construction phase of engineering projects brings new opportunities and challenges to the modern construction industry. In order to give full play to the advantages of BIM technology in cost control, it is necessary to establish a BIM-based cost control system, adopt advanced cost control methods, and strengthen cost control awareness training. At the same time, realizing real-time monitoring of cost control and construction progress, and continuously optimizing cost control strategies are also the keys to ensuring the success of dynamic cost control based on BIM.

When doing business and lending money to others, the biggest fear is that the company will not repay the money it owes and there will be no money in the account. In the end, you will have to look at shareholders for money. Many people's first reaction is to "directly add shareholders as persons subject to execution", thinking that this is faster and less troublesome. However, the latest judicial practice and legal standards in 2026 have made it clear: in most cases, the success rate of directly adding shareholders is low, the cycle is long, and the risks are high. On the contrary, it is not as stable, faster, and easier to execute as "separate prosecution of shareholders".
This article is based on the 2024 revised version of the "Company Law" and the latest enforcement and trial standards of the Supreme People's Court in 2026. It explains clearly in plain language: why additional prosecution is not as good as separate prosecutions, the core differences between the two paths, which one to choose under any circumstances, and the key points of practical operation in 2026, helping you avoid detours and get money faster.
1. First understand: What is "adding shareholders as persons subject to execution" and what is "separately suing shareholders"
Many people can't distinguish between these two concepts. Let's explain the underlying logic first:
1. Add shareholders as persons subject to execution (added during the execution procedure)
This is after the company has won the lawsuit and entered the enforcement stage, and applied to the enforcement court: shareholders who have not contributed capital, evaded capital contributions, or illegal guarantees are directly added to the "list of persons subject to enforcement" and the money is paid back together.
Features: No need to file a new case or pay legal fees. It seems to be "one step done".
2. Separately sue shareholders (sue separately during trial proceedings)
This means that regardless of whether the company's lawsuit has been completed or not, a new civil lawsuit will be filed directly with the shareholders as defendants: suing the shareholders for false capital contributions, withdrawing capital, confusion of personalities, and illegal guarantees, and requiring shareholders to bear personal responsibility for the company's debts.
Features: It is necessary to re-open the case, pay litigation fees, and go through the complete trial process, but the identification standards are looser and the execution is more stable after winning the case.
2. Core truth: Why is “additional prosecution” inferior to “separate prosecution” in 2026?
The "White Paper on Trial Data for Enforcement Objections" released by the Supreme People's Court in the first half of 2026 shows:
- The support rate for adding shareholders as persons subject to execution was only 28%, and more than 70% were rejected by the court;
- The winning rate for shareholders who sue separately reaches 72%, and the judgment can be directly enforced, with almost no need to go through the objection procedure.
There are three reasons why the gap is so big, all based on hard logic of law and practice:
1. Legal threshold: Adding “extremely strict” and prosecuting “relatively lenient”
- Adding shareholders: can only be based on the 7 situations clearly listed in the "Supreme People's Court's Provisions on Certain Issues Concerning Changes and Addition of Parties in Civil Enforcement" (failure to contribute capital, withdrawal of capital, accelerated expiration of capital contributions, confusion of one-person companies, illegal liquidation, etc.), and none of them are supported. The court only conducted a "formal review" and the evidence requirements were extremely high, so it was almost dismissed.
- Separate prosecution: Based on Article 20 (Confusion of Personalities), Article 28 (Obligation of Capital Contribution), Article 35 (Withdrawal of Capital Contribution), Article 63 (One-person Company), etc. of the Company Law, the situation is broader. The court will conduct a "substantive trial" and may support it as long as it can be proven that the shareholder harms the interests of creditors.
2. Procedural guarantees: Adding “the first ruling is final” and prosecuting “the second instance will cover the whole matter”
- If the additional application is rejected: you can only file an "execution objection lawsuit", and the first instance is final (in some areas, the first instance will still be final in 2026). Once you lose, there is almost no chance of relief, and you can only go back and sue the shareholders again, which will add half a year to the process.
- If you fail to sue separately: You can appeal and retrial normally. There are complete procedures for second instance and retrial, and there is a lot of room for error correction.
3. Implementation effect: Added "easy to be kicked back", prosecution "judgment will be implemented directly"
- After the addition is successful, shareholders can still raise objections and reconsider, and the execution procedures are repeatedly delayed and cannot be moved for half a year or a year;
- After winning a separate lawsuit, you will get a valid civil judgment and proceed directly to execution. There will be very little room for shareholder objections and the execution efficiency will be much higher.
To put it simply: Approval is "advancing quickly through a narrow door but it is easy to be kicked out", while prosecution is "advancing slowly through a wide door but it is stable once you get in". In 2026, the judicial caliber will obviously tighten the "additional" and relax the "separate prosecution", in order to avoid excessive expansion of the execution procedure and protect the parties' litigation rights.
3. A complete comparison of the two paths in 2026: understand how to choose from a table
In order for you to see the difference clearly at a glance, the core dimensions are listed clearly (all based on the latest regulations in 2026):
(1) Applicable premise
- Additional: There must first be a valid judgment + entry into compulsory execution + the company has no property for execution, both are indispensable;
- Separate prosecution: There is no need to sue the company first, it can be done at the same time as the company, or the shareholders can be sued separately, which is extremely flexible.
(2) Legal basis
- Additional: Only the situations listed in the "Additional Provisions on Implementation Changes" are strictly legal;
- Separate prosecution: "Company Law" + "Civil Code" + judicial interpretation, substantive fairness doctrine, wider scope.
(3) Evidence requirements
- Additional: Extremely high, "iron-hard evidence" such as industrial and commercial files, bank statements, investment certificates, and audit reports must be provided, and the court will not take the initiative to investigate;
- Separate prosecution: higher but can be supplemented. After preliminary evidence is provided, the court can investigate and collect evidence and commission an audit according to the application, so the pressure of proof is much less.
(4) Trial procedures
- Added: Written review by the execution court, and a ruling will be issued within 15 days, which is fast but rough;
- Separate prosecution: ordinary first-instance procedure, 3-6 months, slow but rigorous, and can be held in court, cross-examined, and debated.
(5) Winning rate (2026 data)
- Additional: 28%;
- Separate prosecution: 72%.
(6) Relief channels
- Additional rejections: When filing objections to enforcement, the first instance in most areas ends in a reversal, making it difficult to overturn the case;
- Failure to sue: normal appeal, final second instance, sufficient relief.
(7) Implementation effect
- The addition is successful: shareholders can raise objections and the execution will be laggy;
- Successful prosecution: the judgment is directly executed and is extremely stable.
4. Practical Guide for 2026: Under what circumstances should you choose "additional prosecution" and under what circumstances should you choose "separate prosecution"
Not all situations require prosecution. Both paths have applicable scenarios. Choose the safest option below:
1. Five situations in which "separate prosecution" will be prioritized (the most common in 2026)
- Situation 1: The shareholder has not contributed capital/the capital contribution period has not expired (the most common) - 2026 caliber: accelerated maturity of capital contribution is extremely difficult to support in "additional prosecution", but in "separate prosecution", as long as the company cannot pay off its debts, the court will most likely support accelerated maturity;
- Situation 2: One-person limited company - it is extremely difficult to additionally require "shareholders to prove property independence"; for separate prosecutions, as long as the confusion is preliminarily proven, the court will ask the shareholders to provide evidence, and the winning rate is extremely high;
- Situation 3: Shareholders withdraw their capital and transfer property - additional evidence is required. If you want to sue separately, you can apply to the court for investigation and audit, which is easier to verify;
- Situation 4: The company is revoked, cancelled, or liquidated illegally - the additional procedures are complicated, and separate prosecution can be more direct by suing shareholders directly for liquidation liability;
- Situation 5: The previous addition was rejected - don’t worry anymore, just file a separate lawsuit. This is the most standard “remedial path” in 2026.
2. There are 2 situations where you can choose "Add" (limited to a few situations)
- Situation 1: The shareholder has clearly confirmed that the payment is due and has not contributed any capital at all, and the evidence is conclusive (industrial and commercial files + bank statements are clear);
- Scenario 2: The shareholder illegally guaranteed and clearly promised to assume responsibility for the company's debts, and the written evidence is complete.
5. Separate prosecution of shareholders in 2026: 3 steps to implement and avoid detours
If you decide to "separately prosecute", follow these 3 steps to make it the most standardized and efficient in 2026:
The first step: fix the core evidence (must be done before prosecution)
- Company debt evidence: contracts, IOUs, judgments, mediation letters, and reminder records;
-Shareholder information: internal industrial and commercial documents (investment information, equity structure, articles of association), ID number/unified social credit code;
- Evidence of shareholder fault: capital contribution flow, traces of evasion, traces of property mixing (mixing of accounts, mixing of personnel), illegal liquidation materials.
Step 2: Determine the defendant and the competent court
- Defendant: directly name the shareholder as the defendant, or the company as the third party (to facilitate the ascertainment of facts);
- Jurisdiction: The court where the defendant is domiciled or the court where the contract is performed. In 2026, most areas support prosecution in the location of the creditor, which is more convenient.
Step Three: How to Write a Litigation Request (2026 Standard Template)
- Order the defendant
Shareholder name/name
Company Name
shall be jointly and severally liable for the debts owed to the plaintiff;
- The defendant is ordered to bear the litigation costs, preservation fees, and attorney fees of this case (if agreed in the contract).
6. Key reminder in 2026: Don’t step on these 3 misunderstandings
Misunderstanding 1: “It’s faster to make additional charges, and if you can make additional charges, you won’t sue separately.”
wrong! Data from 2026 shows that the average cycle for a successful additional prosecution is 6 months, and the average cycle for a successful additional prosecution is 8 months. However, the failure rate for additional prosecutions is 72%. Once it fails, it will take an additional 6 months to prosecute again, and the total cycle is 14 months. Calculating the general ledger and suing separately will get the money faster.
Misunderstanding 2: “If you file a separate lawsuit, you will have to pay legal fees, which is too expensive.”
wrong! Litigation fees are calculated based on the amount of the subject matter, the same as when suing a company, but will be borne by the losing party after the lawsuit is won. Moreover, the success rate of additional lawsuits is high, and it is much better to "spend a small amount of money and win the lawsuit with certainty" than wasting time in vain after the additional lawsuit fails.
Myth 3: “If the company has no money, there is no point in suing shareholders”
wrong! In 2026, courts will intensify enforcement efforts, and shareholders’ personal property (property, vehicles, deposits, equity) can be enforced. In many cases, individual shareholders have more property than the company.
7. Conclusion: For debt collection in 2026, "separate prosecution" will be the mainstream option, which is more stable and reliable.
Judicial practice in 2026 has given a clear answer: adding shareholders as persons subject to execution is a "narrow and dangerous road" with a low success rate and high risks; suing shareholders separately is a "wide and smooth road" with a high winning rate and stable execution.
When the company owes money and there is no money in the account, don't think of "additional" first, and give priority to "separately suing shareholders." Only by fixing evidence, finding the right path, and standardizing prosecution can we avoid detours and realize creditor's rights faster.
The core of debt collection is not to "get quick" but to "seek success". In 2026, choosing the right path is much more important than blindly tossing.

With the development of science and technology, BIM technology plays an increasingly important role in engineering construction. BIM can not only improve project quality and efficiency, but also help project managers control costs. This article will start with the application of BIM technology in cost control, analyze how BIM technology controls costs in engineering construction, and provide a reference for engineering managers.
First of all, BIM technology can help engineering managers establish BIM models of the entire process. In the entire process of project construction, from design, construction to operation, it is necessary to establish a unified and standard BIM model to gather all project information together for real-time monitoring and management. Through the BIM model, project managers can understand the cost situation of each project stage in real time, and adjust and control costs in a timely manner.
Secondly, BIM technology can use budget control methods for cost control. Through BIM technology, the costs of each project stage can be monitored and analyzed in real time, the causes of cost changes can be discovered in a timely manner, and corresponding measures can be taken to make adjustments. For example, in the design phase, BIM technology can be used for cost analysis and optimization to avoid excessive design costs; in the construction phase, BIM technology can be used to manage and control materials and equipment to avoid waste and cost increases; in the operation phase, BIM technology can be used for equipment maintenance and management to avoid cost losses caused by equipment failure.
Third, BIM technology can manage resources to control costs. BIM technology can help engineering managers conduct refined management of various resources, including human, material, financial resources, etc., thereby controlling costs. For example, during the construction phase, BIM technology can be used to coordinate and manage personnel and equipment to avoid resource waste and cost increases; during the operation phase, BIM technology can be used to manage and control equipment and materials to avoid inventory backlogs and cost losses.
Fourth, BIM technology can manage progress and avoid cost increases caused by delays. BIM technology can help project managers manage progress, promptly discover the reasons for lagging progress, and take appropriate measures to make adjustments, thereby avoiding increased costs caused by delays. For example, during the construction phase, BIM technology can be used to analyze and optimize the construction period to avoid cost losses caused by construction delay.
Fifth, BIM technology can carry out risk management and avoid increased costs caused by risks. BIM technology can help engineering managers conduct risk management, discover potential risk factors in a timely manner, and take corresponding measures to prevent and respond to avoid increasing costs. For example, during the design phase, BIM technology can be used to conduct risk analysis and optimization to avoid cost losses caused by design problems; during the construction phase, BIM technology can be used for construction risk management to avoid cost losses caused by construction problems.
At present, Ximatek's BIM engineering cost calculation software realizes automatic cost calculation based on BIM through cost rules, BIM models, contract BOQ items, rule intelligent matching, etc., and automatically generates calculation books and payment orders in real time based on quality inspection results, on-site problem resolution, whether the cost has been completed, etc., reviews the payment process online, and completes the entire cost payment work.
To sum up, BIM technology can help project managers control costs in engineering construction. Project costs can be effectively controlled by establishing a full-process BIM model, adopting budget control methods, resource management, schedule management, and risk management.
Since Musk acquired Twitter on October 27 last year and became CEO, he has single-handedly used "Thanos-style" layoffs, "weekly reports" accurate to the number of lines of code and other workplace "sexy operations" to advance him into an Internet traffic password.
Seeing that he had been silent for a long time, just yesterday, Musk changed the blue bird icon on the Twitter website to a "Shiba Inu". When many Twitter users logged into the website, they shouted: "Is Musk being willful again?"
While everyone was talking about it, Musk responded by posting a picture, saying from the perspective of a "Shiba Inu": "The blue bird icon is a thing of the past!"

At the same time, affected by the "label change", the deeply bundled Dogecoin (DOGE) rose sharply. The move has fueled a surge in the price of the cryptocurrency Dogecoin, from $0.077 before Twitter’s logo change to $0.1046 today, according to CoinDesk data.
(Source: CoinDesk data)
Is Musk deeply bound to Dogecoin?
As we all know, Musk has always been a promoter of Dogecoin. He has expressed his preference for Dogecoin more than once, calling it the "people's cryptocurrency" and his "favorite" currency. He has also posted Dogecoin emoticons many times.
His involvement with Dogecoin can be traced back to 2019.
In April 2019, the Dogecoin community launched an event to select the CEO of Dogecoin, and Musk won the first place in the vote. At that time, he changed his Twitter title to Dogecoin CEO, but it was quickly deleted.
On December 20, 2020, Musk posted 4 consecutive posts on Twitter, mentioning cryptocurrency and expressing his interest in Bitcoin. The price of Dogecoin rose from $0.0039 to $0.0046 that day.
On February 24, 2021, Maska changed his Twitter profile to "Doge all day, Doge all night", and Dogecoin rose by more than 24% in 24 hours.
On May 8, 2021, Musk said on the veteran American entertainment variety show "Saturday Live" that Dogecoin is the future of currency and is as real as dollar bills. However, under repeated questioning by the host, Musk was "forced" to admit that Dogecoin was a "scam." Subsequently, Dogecoin, which was at its peak, fell by nearly 40%.
In 2022, Musk compared his pet to former Twitter CEO Parag Agarwal, jokingly mentioning that it was much better than the other person.
In January, the Financial Times reported that Twitter was designing a system to allow payments through the social media platform. While Musk wants Twitter to be for fiat currencies “first,” he’s seeking to add the ability to add cryptocurrencies, a story that boosted the price of Dogecoin.

In February, Musk posted a post saying he had found a new CEO for Twitter, with a picture of a Shiba Inu. At the same time, Musk said that it is very good, very good at mathematics, and is the perfect successor. After the tweet was posted, Dogecoin rose from $0.082 to $0.087 in a short period of time.
Respond to troubles with logo “big update”
Indeed, Dogecoin has experienced “big ups and downs” under the influence of Musk, which has also caused a lot of trouble invisibly. In June last year, a Dogecoin investor named Keith Johnson accused Musk in the U.S. District Court of continuously promoting and supporting cryptocurrencies, deliberately pushing the price of Dogecoin 360 times over more than two years, inducing others to take over the market at a high level, and then causing the price to collapse. Keith Johnson is asking Musk to compensate him and other investors for a total of $258 billion, which is potentially higher than Musk's entire net worth. Subsequently, Dogecoin founder Shibetoshi Nakamoto refuted Keith Johnson on Twitter, saying: If Dogecoin is a pyramid scheme, then so is the entire cryptocurrency market, stock market, commodity market and monetary system itself.

On Friday, Musk asked a U.S. judge to dismiss the $258 billion lawsuit. Musk's lawyers said it's not illegal to tweet supportive remarks or funny images about a legal cryptocurrency, calling Dogecoin a legal cryptocurrency. From this point of view, the major update of Twitter’s web logo also seems to convey Musk’s own views on this lawsuit.
Netizen: “Is this the ‘Muskification’ of Twitter?”
As we all know, after Twitter changed hands last year, Musk, who took office as the new leader, has made drastic "rectifications" without stopping. First, there was an "unprecedented" layoff, firing key executives such as the CEO, CFO, general counsel, and director of legal affairs and policy. Later, there was a spat on Twitter with engineers whose advice was objectionable. Not only that, Twitter programmers are also required to write weekly reports, and each week they need to submit a summary to introduce the programmer's work this week and the number of lines of code written. Today, Twitter's icon has been changed to a "dog head", which has also triggered an upsurge of discussion. Many netizens said: "You can really do whatever you want with money" and "Musk is willful again". Some people wondered: "What is the intention of this?" Some people bluntly said: "This is the 'Muskification' of Twitter!" What do you think of Musk's new operation? You can leave messages and discuss in the comment area.

Anyone who works in engineering knows that they are most afraid of misreading drawings, fighting pipelines, and making mistakes in calculations. However, the BIM technology that can be seen everywhere on construction sites can eliminate these troubles at once - don’t think of it as a "tall flower shelf" anymore, it has long been a "life-saving artifact" for our front-line engineering workers!
complex graph
As a veteran construction engineer who has worked on site for 12 years, from the earliest days of using CAD to draw two-dimensional drawings and staying up all night to reconcile, to now relying on BIM models to handle complex nodes, I know very well how practical this technology is. Today I will not use official terminology, but use construction site vernacular to explain BIM clearly. Whether you are an apprentice who has just entered the industry or an experienced foreman who has been working for many years, you can use it after reading it.
Let me explain to you first: BIM is not some advanced software. To put it bluntly, it is "Building Information Modeling". The buildings, roads, and bridges to be built on our construction site are "built" on the computer first, and it is a 3D model with full information - as small as the specifications of a brick and the spacing of a steel bar, as well as the progress and cost of the entire project. You can clearly check it in the model.
1. The three most practical functions of BIM are all just needed on construction sites.
complex structure
When we work on site, we don’t look at the virtual, but only look at whether it can solve actual problems. Each of these three functions of BIM can help us save time, save costs, and reduce rework.
The first one is pipeline collision inspection, completely saying goodbye to "fighting and rework".
In the past, when doing electrical and mechanical installation, the most troublesome thing was that the drawings looked fine, but once the work was done on site, the water pipes and cable trays collided, and the pipes had to be cut into walls or re-arranged, which was labor-intensive and material-intensive. I worked on a grand theater project in Nanchang last year, with more than 40 majors, and the optical, mechanical, and electrical pipelines were densely packed. If I relied on traditional drawings to reconcile the accounts, it would take at least half a month, and it would be easy to miss inspections.
Later, BIM was used to integrate the civil engineering, electromechanical, and fire protection models, and the computer could directly mark the collision points. It was clear at a glance where the water pipes blocked the air ducts, and where the bridges and beams conflicted. We adjusted the height and direction of the pipeline in advance. During on-site construction, the workers followed the model without rework, saving hundreds of thousands in labor and materials alone.
Second, with visual explanation, newbies can get started quickly.
Anyone who has worked on site knows that when explaining to workers, it is impossible for novices to understand just by talking or referring to drawings. Especially for complex nodes, such as steel columns tilted at 41 degrees and hyperboloid curtain walls, no matter how detailed the lines on the drawings are, workers cannot imagine how to set up the formwork or install them on site.
Now with BIM, you can open the 3D model, zoom in or out, and it will be clear where the beams and columns are, how to tie the steel bars, and how to build the formwork. Last year, several apprentices came to our construction site and taught them how to read traditional drawings. After half a month of learning, they were still confused. Later, I brought out the BIM model and talked to the model on the spot. They learned it in half a day and made fewer mistakes while working.
The third is to calculate accurately and reconcile accounts without wrangling.
Calculation is a basic skill for engineers, and it is also the easiest place to argue. In the past, calculations were done by hand or CAD, and it was inevitable that there would be omissions and miscalculations. When reconciling accounts with Party A, I would often get angry over a number.
The BIM model is different. As long as you input the drawing information, the software will automatically calculate the number of tons of steel bars, the number of cubic meters of concrete, and the number of square meters of ceramic tiles, accurate to two decimal places, and each item has a basis. When checking with Party A, you can directly call up the model and understand at a glance where there is too much and where there is too little. You no longer have to stay up late to reconcile and argue with each other.
2. Don’t step into the trap! BIM is not “one-size-fits-all”, these two points should be kept in mind
Many colleagues think that as long as BIM is used, all problems on the construction site can be solved. In fact, this is not the case. Based on my years of experience, I would like to remind everyone of two key points to avoid detours.
First, BIM is not about “drawing a model and done”, the core is “accurate information”. If the input drawing information is wrong, it will be useless no matter how beautiful the model is, and it will mislead the construction. For example, if you enter the wrong size of a beam, it looks fine in the model, but you find out after the on-site construction that you have to dismantle the heavy beam, which is not worth the loss.
Second, BIM is not “only for technicians”, front-line workers must also understand it. Nowadays, in many construction sites, BIM is only used by the technical department, and on-site workers still work according to traditional drawings, which cannot play the role of BIM at all. In fact, workers do not need to be proficient in software. As long as they can understand the model and construct according to the model, a lot of rework can be reduced.

3. Summary reminder: Engineers who do not learn BIM will be eliminated sooner or later.
Nowadays, almost all large projects, whether they are residences, hospitals, roads, bridges, or grand theaters, require the use of BIM technology. In the past, you could do a good job relying on experience and calculations by hand, but now you can no longer do it. If you cannot keep up with the pace of technology, you will be eliminated by the industry sooner or later.
Moreover, BIM is not difficult to learn. You do not need to be proficient in complicated operations. As long as you master the basic viewing and application, you can play a big role on the construction site. At the beginning, you can learn from the people in the technical department, look at the models more, and compare them with actual on-site situations. It won't take long to get started.
Finally, I want to ask you a practical question: Are you using BIM technology on your construction site? Do you think it can really improve efficiency, or is it just a "show" to cope with inspections? Tell us about your real experiences in the comment area and learn from each other!
On February 1, Beijing time, Tesla CEO Elon Musk said in an interview with the American social media Clubhouse: "Bitcoin is a good thing, so I am a supporter of Bitcoin."
Musk said he got a share of a Bitcoin transaction in 2013, and many of his friends have been trying to convince him to buy and sell Bitcoin for years. He also said that he should have bought Bitcoin at least 8 years ago, admitting that he was late to the Bitcoin trading fest.
After Musk made these remarks, the price of Bitcoin once rose by $600.
Musk believes that Bitcoin is really close to being widely accepted in the traditional financial field.
Previously, Musk often joked about Dogecoin (Dogecoin, the second largest virtual currency after Bitcoin in terms of user count), but he said that this was actually just a joke. “The ultimate irony is that Dogecoin will become the currency of the planet in the future.”
It is worth mentioning that last Friday, after Musk changed his Twitter profile to "#bitcoin" (Bitcoin), Bitcoin immediately soared to more than 38,000 US dollars, once soaring 18%, hitting a high in the past two weeks.
In fact, Musk has often tweeted about Dogecoin or Bitcoin, which often causes the prices of these virtual cryptocurrencies to surge.
On January 8 this year, Ben Mezrich, the author of "Bitcoin Billionaires," tweeted: "I will never refuse to accept Bitcoin payment again." Later, Musk replied on Twitter: "I will never refuse either."
Earlier, Musk also said that the structure of Bitcoin is very good and that compared to currencies issued by central banks, virtual currencies are more reliable. He also revealed that he only holds 0.25 Bitcoin, which was given to him by a friend many years ago.
