‘Sustainable’ Recording and Preservation of Zangniang Stupa and Sangzhou Lamasery in Qinghai, China with Heritage Building Information Model

Round 1

Reviewer 1 Report

 1

In Step 6: Sustainability of HBIM, Tibetan Niang Stupa through the Heritage Information Model, the author can ensure that the output from this manuscript can continue to record and protect the authenticity and integrity of professional heritage information, and that It is said to be an open and sustainable online management platform.

 

The author says that conservation agencies and government agencies have even stated that they can regularly collect heritage information and update and share the HBIM information model in a timely manner, but no specifics exist.

Also, what is conservation agencies and government agencies?

 

2.  

What is the format of a sustainable online management platform? they cannot be found at all in this manuscript.

 

3.  

In Chapter 2, the methodology is mentioned, but only the general method is being repeated in this manuscript. Please tell us the specific methodology through your manuscript.

 

4.  

In the HBIM Sustainable Process for the Zangniang Stupa and Scripture Hall, the sustainable HBIM process is not properly mentioned in Chapter 3. It is merely an explanation of what is in the HBIM Program Manual. New proposals on how to build HBIM as a study are needed and proposed in this manuscript if the authors intend to regard this manuscript as a systematic record.

 

5.  

The rough structure of this manuscript is composed of two kinds, the first is about the concept of HBIM, while the second is about the process of building BIM by Tibetan Niang Stupa. The authors say that HBIM technology is used for the systematic recording, preservation, and management of historical building information. But there is no specific DB lists (there are no concrete inventories) for building information. What information are the authors referring to as systematic records? If they will be simply about information construction on wooden members, I confirm that the authors have the wrong concept on the HBIM’s systematic records. according to the Methods for Recording the content of Chinese Tibetan Architectural Heritage Information, they are not intended as a systematic record.

 

6.  

You mention as follows, “additional researchers, designers, restorers, and monitoring personnel can also use the HBIM information model at different time periods to conduct more research work and formulate scientific protection and restoration plans.” However, there is no specific process for the restoration and protection plan mentioned by the author in the manuscript.

7.  

You mention as follows, “This will achieve the purpose of the regular and sustainable protection of heritage, both online and offline.”  If so, the authors have to figure out what attributes you can do to build heritage information offline and online.

 

8.  

What is the management of historical building information and the collaborative work mode for convenient sharing and transmission of information? In particular, this manuscript lacks the concepts and specific methods of collaborative works. That is, this manuscript never does mention them.

 

9.  

In addition, there are no contents for Figure 13 to Figure 17. This means that the current manuscript is not complete.

 

10.  

Overall, this manuscript lacks a lot about the notion of the HBIM process and platform.  The authors have to provide specific details on how to build a sustainable HBIM and how to structure the content of the platform.

1:

Thank you very much for your question!

The government institutions referred to in this paper are local cultural relics protection units, and their main tasks are responsible for acceptance, investment and management.

Protection institutions are mainly protection associations, universities and scientific research institutions. Their main tasks are responsible for surveying and mapping, collection and modeling, which includes different roles such as technicians, managers and researchers.

To avoid ambiguity! This paragraph can be changed and deleted again. Please refer to it.

2:

Thank you very much for your question! This is indeed the key part of the article that has not been fully explained!

The sustainable management platform mentioned in this paper is mainly based on abd and synology drive client software, and is realized by the network synchronization function of synology drive client software. This method is different from many direct connection schemes. It is based on a two-way synchronization scheme. Different work results can interact with local data terminals with the help of synology NAS server, so as to realize the sustainable update, feedback and protection of heritage information model. This method makes hbim cheaper and more convenient, and can still achieve sustainable and collaborative work even in the context of the global pandemic.

I have added this supplementary explanation and illustration to the discussion in the last chapter of the article. Please refer to it.

3:

The method of this paper mainly focuses on the field investigation method and experimental method, and mainly focuses on the research on the function of information command and sustainable management of hbim. This method is a feasible method and conclusion put forward through a lot of practice and summary.

I have moderately revised and explained the methodology, please refer to it.

4:

Thank you very much for your comments. I have added the specific time process and content in the new chapter 4. Please refer to it.

5:

All models in this paper are based on the actual surveying and mapping results, including wood structure, wall structure, copper components and internal cabinets. As shown in the catalog Styles dialog box in Figure 9, figure 11 and Figure 17, especially Figure 17 is only the display of "queti" wooden component information. Therefore, each construction part has corresponding data information. Please refer to.

6:

This is not the most important issue discussed in this paper. Due to the limitation of the number of words and length of the paper, this paper does not discuss how different personnel use abd and synologydrive software to carry out specific repair and protection plans, but envisages that different personnel use the information model provided by abd as a reference and medium to guide the formulation of future protection and repair plans. In addition, the focus of this paper is only the exploration of how to realize the sustainable work and platform of hbim.

Thank you very much for your comments. I think I have found a good topic to carry out the next stage of research. Of course, in order to avoid ambiguity, I will delete this paragraph. Please refer to it.

7:

Thank you very much for pointing out! What this paper wants to express is that different staff can carry out the construction of information model whether they are on site or not. To avoid ambiguity, I have deleted this sentence, please refer to it.

8:

Thank you very much for your reminder! After deep thinking, I also raised questions. I have written the pictures and texts into the newly added Chapter 4. Please refer to it.

9:

I have added content to the picture in combination with the context. Please refer to it.

10:

Thank you very much for your reminder! I also found this problem. I have written the picture and text into the newly added Chapter 4. Please refer to it.

In addition, I also add some of my own views. At present, hbim is not widely popularized and used in China. The hbim methods proposed for different types of heritage are also different, but most of them are perfunctory after they are built. Many technical routes with sustainable recording, management and protection platforms are still in the exploration and experimental stage, and the development cost is high, which can not be realized by small teams. I think we still need a lot of practice and efforts to solve this problem in a "one-stop" way.

Therefore, the hbim sustainable working mode and platform based on abd and NAS server proposed in this paper is the easiest to realize at present, especially for the protection of architectural heritage information in remote areas of Western China, as well as many local protection associations and government units. In addition, the information modeling of Tibetan Buddhist buildings and pagodas is also very rare in China. We also encountered many problems in the modeling process, and summarized and broke through many technical difficulties in model building, which is valuable.

Thank you again for your guidance and advice！！

Reviewer 2 Report

This paper presents the process of surveying of the Zangniang Stupa and Sangzhou Lamasery in Qinghai, China. It describes the conditions of the Heritage question in China, the importance of the HBIM approach, the workflow adopted and presents examples from the survey process performed and from the data organisation criteria, and some of the final visual outputs. In general, the paper is well organised and the process is clearly described.

Despite words such as ‘sustainable’ or ‘sustainability’ counts some 40 entries in the paper, it is not clear why this specific survey and modelling experience should be considered innovative in the sustainability. In my opinion, such a process can promote sustainability in three ways: digital remote surveying tools and a BIM model can reduce the necessity to work on site for many days, saving the operators the need of many travels and allowing them remote working; a BIM model is open, integrable and available to become a collaborative open-source tool, which is a way to spare the repetition of studies and surveys on the same site; a BIM model is an opportunity to better plan and realise the future management of the building by optimising resources. Anyway, most of these potential benefits are conditioned by the policies about its use as well as the users’ behaviours. On the contrary, it promotes a growing use of electrical and electronic devices as well as the on-line transmission of data (we are informed that the huge Data Centers are currently becoming a relevant subject in world electricity consume).

However, as these opportunities and problems are well known, the authors are expected to explain the way their work is innovative in the field of sustainability.

Maybe they have a peculiar idea of sustainability. For example, when mentioning the problems of traditional documentation of historical heritage in China, the state that “The information sources are unreliable, unsystematic, untrue, incomplete, and unsustainable”. Which sense the adjective ‘unsustainable’ is here used for?

Again, “Thus, we have moved past the 'information island model', which made referencing and 120 associations inconvenient, and into a new era dominated by the multi-temporal, sustainable, and traceable HBIM method”. Is every ‘BIM method’ sustainable?’

Added to this, some little grammatical corrections are required and a clear choice between American or British English must be done.

Thank you very much for your approval and suggestions! This is very important to me! I have added your suggestions to the paper.

2-3:

Thank you very much for your question! In terms of software practicability, many BIM software can achieve sustainability in operability, but this does not mean that all BIM software can be suitable for building heritage information model, nor does it mean that every BIM method and idea is suitable for all types of buildings. What this paper proposes is the optimal solution obtained through a lot of practice. We rely on this method to achieve sustainable development throughout the epidemic period. The newly added fourth chapter of this paper explains the choice and method of BIM software! Without you, there would be no my fourth chapter!

4:

Thank you very much for your question! Both Oxford and Cambridge dictionaries interpret the word "sustainability" as "the quality of being able to continue over a period of time" or "to keep alive". However, the recording and work of heritage information in China has always been one-way, even intermittent, and the use of BIM software in the field of heritage protection has not been popularized. Many teachers and students are not interested in hbim at all! For example, the repair work of Jiayuguan in China has only been repaired and surveyed twice in decades, and the heritage information source has been missing and fragmented to varying degrees. This also leads to many components can not identify the development process, and the protection plan can not start. The emergence of this situation will inevitably lead to the "unreliable, unsystematic, untrue, incomplete and unsustainable" of heritage information.

Reviewer 3 Report

Dear Authors,

Thank you very much for your manuscripts. At first glance, I am interested with the topic of your research. However, I am convinced that the manuscript needs to be rewritten before publication. The manuscript's weakness is the lack of a conclusion. Otherwise, the summary section needs to be further developed. You need to point out what are the disadvantages of the HBIM technique. You should completely introduce all aspects of the HBIM before applying it to your research. In addition, please kindly consider the following comments and I do hope that you find them useful in improving the quality of your manuscript:

1. Line 31: delete "(13-14)".
2. Line 32: Thesis of Murphy? Are you sure? I did not see any reference to his thesis in reference section.
3. Line 61-62: "modifications" of what?
4. Line 62: "The innovation of this paper is its exploration ...". It's better to check English language to have a meaningful sentence.
5. Reference [1] and [15] are the same.
6. Line 82: Delete "(1-3).
7. Figure 1: In my opinion, arrows are needed to show relationship between "sustainable" with "traceability" and "diversified information sources".
8. Line 188: What does "UAVs" stand for? I understood it but general (non-academic)  readers.
9. Line 202: What does "IFC" stand for?
10. Figure 2: "hbim" should be in capital letters.
11. From page 10, the order of figures are not correct.
12. Line 283: Definitions of "ZNT" and "ABD" are needed.
13. Line 352: " However, there are still many deficiencies that need to be addressed." Please kindly develop this sentence! What are those deficiencies?
14. All pictures should be properly formatted.
15. Only a heritage building (stupa and lamasery) was taken as an example. Is it sufficient for generalizing the application of the HBIM model in the field of heritage architecture? This is just food for thought but what I mean is the tittle of your manuscript.
16. In the  Acknowledgments section, I do not think that this section is dedicated to the 1st author to say thank you to 2nd and 3rd authors?!?
17. Name of 3rd author: Cong Wu or Cong, C.?!? (Line 5 and line 357).
    
    Best regards,

Re-comment 2

Cultural heritage must be treated with respect, unlike ordinary modern architecture. So, is the author's thinking focused on the easy management of cultural heritage? Will this practice become obsolete after the pandemic is over? In my opinion, it should be more sophisticated. If you do it in a simple way, there is no reason to apply BIM. Because BIM is for the systematic management of cultural heritage.

The Reviewer is very concerned about the author's approach.

The method of this paper mainly focuses on the field investigation method and experimental method, and mainly focuses on the research on the function of information command and sustainable management of hbim. This method is a feasible method and conclusion put forward through a lot of practice and summary.

I have moderately revised and explained the methodology, please refer to it.

Thank you very much for your comments. I have added the specific time process and content in the new chapter 4. Please refer to it.

 

Re-comment 4

Chapter 4 is a story that can be used in modern architecture as well. In connection with the characteristics of the cultural heritage (Tibetan Niang Stupa) selected by the author, the proposal should be differentiated from the existing platforms.

 

 

 

 

5: comment 5

All models in this paper are based on the actual surveying and mapping results, including wood structure, wall structure, copper components and internal cabinets. As shown in the catalog Styles dialog box in Figure 9, figure 11 and Figure 17, especially Figure 17 is only the display of "queti" wooden component information. Therefore, each construction part has

 

corresponding data information. Please refer to.

 

Re-comment 5

What I want to know is how to systematically classify the total information of members on the cultural heritage. The classification method seen in the current manuscript is very distracting.

I am curious about how they are arranged in order after the heritage is divided into foundation- building body-roof parts, for example, when listing bracket-sets, I would like to know how they are arranged in order with the BIM framework.

Because each cultural heritage has its characteristics, the heritage management direction that meets the evaluation criteria should be established depending on the value evaluation of individual building members in the heritage. After such measures, for conservation and management, you must decide the things that need to be managed intensively according to these members.

If so, what are the basic principles for managing them with the BIM tools?

What is included in the attribute information of each member? For example, does the attribute information include repair history, materials, fitting methods, etc.?

In this manuscript, there is no method on how to fix them in the HBIM system when there are replaced building parts from the heritage.

Please write again.

In the case of “Figure 9: Basic component information library of "Data system", the property information is not visible at all.

It seems that it is necessary to apply the LOD criteria differentially for each member. What are the principles for the LOD criteria and the LOI criteria and what information should be put in the BIM Platform?

 

Please clearly show the relationship between Figure 11 and Figures 8, 9, and 10. There is no connection at all.

Replace all Chinese characters in Figures 8, 9, and 10 with English.

Without correction, non-Chinese readers will not understand what the author is saying.

This journal is written and submitted in English, not a journal that can be written in Chinese.

 

Where is Figure 17?

 

Please also reply to comment 5 again. I did not ask the question to get this general answer.

The rough structure of this manuscript is composed of two kinds, the first is about the concept of HBIM, while the second is about the process of building BIM by Tibetan Niang Stupa. The authors say that HBIM technology is used for the systematic recording, preservation, and management of historical building information. But there is no specific DB lists (there are no concrete inventories) for building information. What information are the authors referring to as systematic records? If they will be simply about information construction on wooden members, I confirm that the authors have the wrong concept on the HBIM’s systematic records. according to the Methods for Recording the content of Chinese Tibetan Architectural Heritage Information, they are not intended as a systematic record.

Re-comment 6

In terms of Sustainability, the problems of this manuscript have no consideration for the conservation and management of cultural heritage. The author must supplement that part.

The BIM system you proposed has already made many proposals for modern architecture.

Does the author’s manuscript now take into account the characteristics of individual cultural heritage from point of Sustainability view?

What is the difference between your research in this manuscript compared to the previous studies? I don't see any difference at all.

Is the author a professional researcher of cultural heritage?

In my view, the author does not understand the characteristics of cultural heritage at all. You should think more seriously about this issue.

I can't find the answer to my question in Chapter 4.

Please revise the parts the I indicated in the manuscript again.

Please reply again.

What are the management of historical building information and the collaborative work mode for convenient sharing and transmission of information? In particular, this manuscript lacks the concepts and specific methods of collaborative works. That is, this manuscript never does mention them.

I have added content to the picture in combination with the context. Please refer to it.

 

Re-comment 9

I can't understand your answer. The explanation of Figure 13 to Figure 17 is very general. Chapter 4 has absolutely nothing to do with parts of the cultural heritage. What is this manuscript talking about? Is it sustainable conservation of cultural heritage? Would this approach be Sustainable’ Recording and Preservation as your manuscript title suggests?

  If so, please reorganize the contents of Chapter 4 using the tools you have in mind to fit the characteristics of the cultural heritage.

If the summary is the conclusion, spend more time on the conclusion.

Re-comment 10

Your answer points out the limitations of this manuscript in the conclusion. And you are still worried about the compatibility or universality of your ideas. Is the content of this manuscript suitable for Sustainable Recording and Preservation? The methods you suggested will only last a year or two.

Will the next alternative be the HBIM that will be distributed in the future? If so, how to link current methods with BIM compatibility should be important content in this manuscript. If that content is included in Chapter 4, then this manuscript will be meaningful as a thesis.

Response letter

《‘Sustainable’ Recording and Preservation of Zangniang Stupa and Sangzhou Lamasery in Qinghai, China with Heritage Building Information Model》

Thank you for spending time reviewing our manuscript and providing us with a list of constructive comments！

We understand that you have several significant concerns about this article. For example, will this method become obsolete? Should the method be more complex? Is the platform not targeted at cultural heritage? Is the information classified correctly? How is the hbim information framework of the heritage arranged? Are there any methods to repair and replace components? Are different builds graded according to various attributes? And so on. To solve these concerns, we modify them one by one:

Response 2

Thank you very much for your comments! I have the following three understanding points in response to your question. I hope to give you a relatively satisfactory answer and explanation.

 

• Because the novel coronavirus pneumonia has brought global people to the importance of "online office", we can save a lot of commuting time to ease global energy consumption and traffic pressure. I think the working mode of "online office" will not be outdated for a long time and will inevitably become a trend. The method I proposed is also based on this background. Like the hbim “sustainable" recording and management method I suggested, it is a quickly popularised heritage information management method. It has the practical value and significance of "throwing bricks to attract jade". In addition, in the project of Zang Niang pagoda and Sutra hall, all staff can be familiar with and master the software operation within two days, build the information model within seven days, and be fully competent for the information model construction of other types of architectural heritage. Therefore, this method will not be outdated but will be widely used and continuously improved.
• I think the simple HBIM operation method is suitable for protecting the heritage information of "ZangNiang pagoda and Sutra hall". First of all, "BIM" is an engineering data model based on three-dimensional digital technology and integrates all relevant information of construction projects. At the same time, the "Zang Niang pagoda and Sutra hall" information model also integrates many heritage information and is the direct application of digital technology on this object. It can provide architectural heritage information and a "visual" HBIM model for more researchers and protectors, so it is a successful example. Compared with the previous information recording and protection mode, the use of BIM in this project is meaningful.
• I need to reinterpret the concept of HBIM: The term Historic Building Information Modelling, abbreviated as HBIM, was first used in 2009 in a scientific article by professor Murphy of the Dublin Institute of Technology.

This term indicates a new way of modelling existing buildings, using a BIM process that would produce intelligent models containing and managing information. Such models are obviously related to project components and include their geometric and identifying information and all the physical properties that best describe them.

 

The first attempts to create a BIM model of an existing building are linked to historical or monumental building types. The aim was to generate a database to include models created to be inserted and relating information.

 

HBIM is a process applied to existing buildings, whether monuments or simple dwellings of the 1950s, significantly increasing the potential of BIM technology! HBIM can also be used to existing building models in terms of digital and geometric 3D reconstruction and as a methodology involving intelligent models with added information.

 

Basically, HBIM does not define a new type of design, but it explicitly defines how to work with its applications. It is a technology that allows to reproduce an existing building and to create a model that can simulate its actual construction and that, in the end, provides most of its features in the most feasible way.

 

With HBIM, a sort of “reverse engineering” is applied to existing buildings. When a building is modelled, the procedures that led to the construction of that particular kind of building are then analysed, simultaneously improving the modelling process itself.

 

University research institutes are explicitly trying to demonstrate that BIM applied to existing buildings could facilitate the conservation and management of the built heritage.

 

Today we know that starting from a point cloud with a certain resolution, it is possible to create an intelligent and parametric model that will contain the highest number of information relating to the building.

 

In addition, it is worth noting that many BIM tools have not originally been created for modelling an existing building but mainly for new constructions. Ongoing research is analysing new ideas and procedures to make the whole flow of operations fast and automatic. The operations are carried out from the point cloud to reach the building’s final model without losing too many details and information.

 

Response 4

Thank you very much for your suggestion. The current BIM software is developed for "new" buildings. It is not developed for "existing" architectural heritage. This is a software technology and function problem, so it can not be wholly distinguished. However, in response to this opinion, we have revised Chapter IV.

 

Response 5

Thank you very much for your suggestions. I will answer your questions regarding classification method, BIM information framework, component management, construction information, LOD and LOI standards, picture information, etc.

 

• For all of our component information classification, we have formulated specific classification standards, which are divided according to "component name - area - component part - orientation - number", such as the square column, SC-1-SH-F-001 (Square Column - No. 1 area - Scripture Hall - Front - No. 1 Component).
• The modelling and combination arrangement of all model objects are based on the arrangement of "component function", that is, the information models of Tibetan Niang pagoda and Sutra hall are divided into components such as foundation, roof and wall based on "architectural design" and "structural object" in "data system interface" in ABD, so the structural components in different model objects may appear in the same "structural object" framework. In Figure 7, take "side code wall" as an example.
• The value evaluation of each part of the architectural heritage component is determined according to the research and discussion of the heritage expert group, which will be a long-term and complex process. At present, the main focus of our work is how to effectively and sustainably record this valuable information, and ensure the safety and effectiveness of data in the process of the display, research, query, update and so on through appropriate management. In addition, this paper will not choose different management methods according to the value of different components at the current stage but "treat the value of all components equally". Therefore, the principle of using hbim to manage all components is to ensure that the information contained in each heritage component entered is accurate and that the data for each element is accurate in the exchange process. Of course, your opinion is still an important topic. We will continue to study the management methods of different builds in future research and carry out more practice and verification.
• At present, it is the first time to carry out mapping and information collection for Zang Niang pagoda and Sutra hall, so all building component information is mainly based on its physical characteristics, and there is no maintenance history to be supplemented. As for the assembly method of building components, because the current building is an "existing" architectural heritage, only a more thorough study of the development and evolution of the whole architectural heritage is needed. It can be entered into the component information database. However, we will still supplement such information in the protection and investigation of "Tibetan mother pagoda and temple" in the future.
• As for the method of repairing and replacing parts in hbim, since there is no problem of replacing and repairing components in the current protection object, we can only add a relatively reasonable idea in Section 4.3 of Chapter IV in combination with the modelling experience and process of ABD.
• With regard to LOD and LOI, all components of the hbim of Tibetan Niang pagoda and Sutra hall need to meet the basic delivery standards mentioned in section 2.2.2. As mentioned earlier, ancient buildings are not like "new" buildings. Many components are changeable and in different forms. We propose different LOD and LOI standards for each component, which will be a long process that must be discussed and studied. This part does not affect the discussion and Research on the "sustainability" of hbim in this paper. Of course, your has put forward an essential opinion to this article, and we will also carry out special research and discussion in future research.
• As for pictures, we have integrated Figures 8, 9, 10 and 11 into Figure 7, supplemented most of the missing information in the interface, and replaced important information with English. In addition, all pictures have been modified and integrated; please review.

Response 6

We understand that "sustainability" lies in "sustainable collaborative work" and "sustainable information update and management". As for the current stage, what if management? We discussed it in the previous reply. As you said, the characteristics of different types of cultural heritage are also an important issue. For example, different periods, different styles, different cultures, different geographical environments, different technologies and other material and intangible heritage will affect the state of architectural heritage.

 

However, we want to clarify that these factors do not affect the construction of the hbim model and "sustainable" information input and management, and make the heritage information protection and management of Tibetan mother pagoda and Sutra hall get rid of the "information island model". In addition, from the perspective of "sustainability" of different cultural heritage characteristics, we believe that this requires the development of better BIM management software. Because the current BIM software is more developed for "new" buildings than for "existing" architectural heritage, many different information sources related to heritage cannot be entered into the current BIM software, even abd. Of course, your suggestion is a perfect topic, and we will gradually explore and study it in our future work.

 

There are many differences between this paper and other papers, such as how to use ABD software as an architectural heritage information management platform, How to use ABD to build an information model, How to use ABD and NAS server to create "collaborative" and "sustainable" information entry methods. In addition, this paper puts forward the platform framework of hbim sustainable information protection and management based on abd and Synology drive. It verifies the sustainability and feasibility of the hbim model.

Response 8

We have reinterpreted the "collaborative work mode" in Chapter 4. Referring to figure 13, this paper’s collaborative work mode of information sharing and transmission is based on the information model platform built by NAS server and ABD software. I have re-expressed the collaborative work mode in the way of pictures. Please check it.

Response 9

Our work is mainly to record these component information effectively and sustainably, not to propose "sustainable protection of cultural heritage" based on the platform. Our main task is to borrow the hbim model and ensure the safety and effectiveness of data in the process of display, research, query and update through information management. Of course, there are still many deficiencies in this article. We have summarised the problems in the final conclusion. Please check it.

 

Response 10

• Thank you for your suggestions and comments. The method proposed in this paper is suitable for the "sustainable" recording and preservation of many temple buildings in Tibet. The Tibetan Niang pagoda and Sutra hall are successful cases. In addition, whether this method is outdated and meaningful, I have answered the second question. We think this method can only be better and perfect, not just last for a year or two.
• The IFC format mentioned in this paper is based on the ABD management platform to generate BIM data. The IFC format file has good interoperability. It effectively avoids the problems that BIM data cannot be accessed, circulated and shared. In addition, in terms of downward compatibility and upward compatibility, ABD software has its own compatibility advantages, which is discussed in Section 4.2 of this paper, which is why we use ABD as a hbim platform.

Reviewer 3 Report

Dear Authors,

Thank you for the revised manuscript. You answered most of my questions and comments. The rest is as follows and I think they should be corrected / considered before resubmitting:

1. The references [1] and [15] are the same. It's redundant.
2. There are 2 figures having the same name "Figure 12".
3.  Figure 4 or should it be considered as a table?

Kind regards,
