1. Is BIM helpful to integrate green building measures? And is it possible to achieve any green building rating using BIM?
Yes…As discussed, BIM as a concept is to be implemented across full project life-cycle…However, the tools used, the level of detail and the information incorporated into the models vary basing on the model usage...In this case Green Building Rating related information and formulae can be incorporated in to the BIM Models.
2. Can you suggest a very simple and quick 4D BIM tool that is user friendly and can be used by Planners and Project Control professionals who may not be very adept with advanced BIM software and tools ? For example, some quick and simple 4D tool to integrate with simple schedules in MS Project, Primavera, etc.
Within the open forum we do not prioritize a specific software / vendor. However, the technology is fairly advanced for team members to start using BIM for 4D with minimal training required. Please feel free to contact me via email for a further conversation.
3. Integrated means including civil, structure and finishing? Or only services
Integrated means all disciplines that are being modelled as part of the BIM Scope of work for the project. This typically includes Architecture, Structure, Façade, HVAC, Plumbing, Fire Protection, Landscape etc.
4. At what stage we should introduce the BIM for services?
The earlier the better. BIM models for services can be developed at various levels of detail starting from Conceptual Design for zoning itself. However, the current industry trend starts developing MEP models at the design development stage.
5. When can we expect first clash analysis report? During detail design?
First clash report is typically generated to identify coordination issues between Architecture & Structure Disciplines.
6. HI, Can implement Fenestration products such External windows, doors etc in BIM, With exact details and can we also use for making BOQ of the material required for different items , such frame, sash, hardware etc.. ?
Yes…BIM Models can be developed including the details mentioned by you…However, it is important to make sure the models carry right amount of information for the BIM Uses identified…This will help to make sure models are clean and light.
7. In India nowadays, multiple govt departments include bim in project scope for EPC turnkey jobs as it is mandated by cpwd. But the departments are not sensitised to the expectations from and/or capabilities of BIM. The result is that BIM modelling becomes just a compliance exercise. The question is, how much should the contractor be held responsible for training the employer?
This very much depends on the type of terms and conditions documented within…BIM Requirements should be mentioned in detail along with the tools and LOD information in the contract documents…This will help to ensure that contractors are fully aware of the skillset and experience required by the project.
8. I am from Construction company. Lot of BIM consultants are available. What is your suggestion? Should we get it done from these consultants or to developed in house team?
This should be a decision made after under sting few key points…such as existing project deadlines, current team skill set, specific BIM goals in place…We typically call this as "Assessment" to understand the above items in order to prepare a BIM Implementation Roadmap
9. Do you suggest the similar development of Interior Projects in BIM as the timelines for Interior Projects is hardly 60 days ?
Interior Projects will benefit greatly with BIM by being able to avoid coordination issues and more importantly to be able to generate very accurate quantities.
10. What do you have to say about the size of the BIM models? They become heavier and heavier the minute you start adding details to them. More and More services are added to them. Please suggest how to keep the model light so that it easy to use?
Most of the cases, model file size is directly proportionate to the model quality. However, it is very important to have a well-planned "Model Breakdown Structure" in place to ensure file sizes are manageable.
11. In Projects where we are using BIM , how do we quantify or establish change management?
Change management for existing projects will not be very different from new implementations…First step would always be to bring all project team members on to the same page and ensure the project requirements are communicated. A good BIM Execution Plan is very helpful for Project Specific BIM Implementation
12. If any consultancy services used for any project how much it cost example in 1000 cr project?
Costing depends on the BIM Scope of work…Feel free to contact me directly with basic project information to have a more detail conversation. ( email@example.com )
13. Which are the entry level or most cost-effective BIM software?
Within the open forum we do not prioritize a specific software / vendor. However, the technology is fairly advanced for team members to start using BIM for 4D with minimal training required. Please feel free to contact me via email for a further conversation. ( firstname.lastname@example.org )
14. Please throw some light on BIM specific contracts
There is no 1 template that suits everybody's contractual requirements. One should agree on the BIM Scope of work for a specific project basing on the benefits and skillsets that are available for the project. BIM Contracts should clearly define the BIM Use Cases, Roles and Responsibilities and other Model specific information in order give a clear understanding to both the parties.
15. To what depth the models could be used for O & M?
The life cycle of BIM Models managed properly can be utilized across the building life-cycle. Primarily after converting design & coordination models into As-Built models, the next logical step to expand the model usage to operations and maintenance. This we typically start with identifying and incorporating Asset related information into the BIM Models which results in AIM ( Asset Information Models ) . There are existing tools in place to use BIM Models to efficiently manage maintenance activities including ticketing, checklists, warranties etc...Feel free to write to me at email@example.com for a deep dive conversation into BIM for Operations & Maintenance.
16. We have talked about process of implementation…. But major problem is collaboration using diff software. How to deal with this?
"Open BIM" as a concept enables the software interoperability issues to a large extent with the help of IFC file formats. However, choosing the right set of tools that are interoperable is a key decision to be made early in the process.
17. Any way can you shed some light on use of COBIE standards in O & M model?
COBie as a standard is specifically made to bring an organized approach toward documenting non-geometric information specific to project assets. Since COBie standard is more on a spreadsheet format it enables for higher level of interoperability between BIM and legacy O&M tools. Feel free to write to me at firstname.lastname@example.org for a more detail conversation on COBie and how it can help in your existing projects.
18. Can you please elaborate difference between EIR and OIR
OIR - Organizational information Requirements are at a high level discussing the company’s objectives, technology needs etc. This can also include file formats, data requirements from various departments etc.
EIR - Employer Information Requirements are more specific to a project discussing what is expected from the contractors / consultants in terms of the over scope and technology related items. This can also include standards about how the information exchange should take place during the course of the project.
19. Can we discuss the possibilities of using BIM for Addition / Alteration projects? A sizeable part of the industry works with addition /alteration work?
BIM for existing projects has a clear benefit of being able to document the current status of the project in 3D with the help of legacy 2D drawings or Scan to BIM Technologies. This primarily allows the teams to start with an exact representation of the existing structure in BIM which can further be used for design exploration, quantities and continue into construction and maintenance
20. What’s your point of view...will BIM play an important role in architecture after this covid 19 ends (in terms of time saving) ... Your take
BIM has already become a common practice in the construction industry across the globe and India will follow the same post COVID 19 ….However COVID19 is a very good example for corporations to realize the importance of have standard operating procedures documented for the entire project life-cycel and further into implementing latest technologies to improve team efficiency...
21. What do you mean by model breakdown structure?
Although BIM as a concept will be made of a 3D model as a single source of truth, and typical project requires multiple models to be developed basing on the project scale and BIM requirements. A model breakdown structure will clearly define how many files to breakdown the project into so that it can be easily managed.
22. Can you share information about Facade integration in the BIM
We perceive façade as one of the primary disciplines needed to be modelled as part of any project. Apart from typical design coordination and construction planning activities, BIM models developed for Façade can further be used into light penetration, solar heat gain analysis etc..
23. Being worked in multiple countries with varied penetration levels of BIM, what do you think, which country has the best policy in place and a country that is approaching on high speed.
This would be a good point to dive into few years ago where BIM was still in its nascent stages…However, several countries have gone past the early stages of implementation…I primarily enjoyed the support ( financial & knowledge ) provided by Govt. Of Singapore to the industry laid a strong BIM implementation pathway.
24. How does BIM help in improving detailed design and how can it be actually implemented on-site?? An example in terms of highway implementation will be appreciated!
BIM for infrastructure as a concept works very similar to construction projects. The major difference here is to identify specific tools available for BIM for Highways and the standards & templates that are to be setup for the project. A good example to quote is one of the projects we worked with Public Works department Indonesia where we organized the entire BIM Modelling activity along with training and design development support for multiple highway projects. Please feel free to write to me at email@example.com for a more detail conversation.
25. Any Standard in preparation in India for BIM Standardization sir?
It will be hard to define a specific standard for BIM especially for Indian market given the scale and various categories & teams typically involved. BIM Standardization should start at an organization level by understanding the specific goals and objectives.
26. Hi, it was indeed good presentation. Can you please guide, shall we use in office interior and to project management? How far shall we use. I mean what level of details. Thanks
BIM Uses for an interior project has major benefit in being able to accurately quantify the material and assets needed…I have personally noticed several 2D projects with major design and quantity variations that can greatly benefit by having a BIM Model in place...For any project LOD300 is sufficient for typical project management activities.
27. As lot of our consultants and contracts are not into BIM. We end up exporting all the drawings in AutoCAD which effects the quality of the final product. Is there any way where we can reduce the impact on the final product?
As mentioned in the presentation about BIM Levels of maturity…this is main disadvantage of working in Level1 BIM…My advice is always to push consultants to take the steps needed to implement BIM at a project level…It is important to influence your entire ecosystem to move into Level2 BIM so as to gain the real benefit of the models developed by your team.
28. What kind of training does management needs to take before BIM execution?
Management level training typically involves more at a conceptual level to ensure everybody realises the importance of BIM implementation. During this session we typically discuss organization level BIM Goals, Objectives, Planning a BIM Road Map , Contractual documentations etc..
29. What are the chances of data loss while converting scan to BIM ! Thx
Converting point cloud data to BIM Model currently is a highly manual exercise where the BIM Modeller traces over the point cloud data to create the model. I would say data loss is primarily is based on the modellers understanding of the project and also the supporting documentation available for the building
30. Short description on LOD 300, 400, 500 & 600
LOD 300 - BIM for Coordination, Quantities and Planning
LOD 400 - BIM for Shop Drawings & Assemblies
LOD 500 - BIM for As-built Models
LOD 600 - BIM Operation & Maintenance Models
The definitions are varying from different sources. Which is the reason why we emphasize on the detail LOD Documents that are generated for a project to define the scope of work accurately
31. With BIM can we do Delay Analysis on project implementation
Yes, BIM models when integrated with Construction Schedule - planned vs. Existing can be compared in 3D to understand the project delay and can also plan the mitigation activities accordingly. This is 4D BIM - Where BIM Models are integrated with Time.
32. Can it be use for the large projects and other team members work on same file at same time. Like we have xref in AutoCAD
Yes, Cloud based technologies for BIM are now evolved to support organizations working from various offices to access the same BIM model for live design coordination. Feel free to write to me at firstname.lastname@example.org for a more detail conversation on BIM Cloud based implementation.
33. Can we get render model in BIM? Like Vray ?
Yes.. Most of the BIM Authoring tools provide rendering features that are matured enough to produce high-quality renders… BIM Models can also be exported into other mainstream rendering tools for material, texturing, lighting, and rendering as well.
34. How to integrate MS Project Planning module in BIM?
BIM for Construction Simulation requires a different set of tools other than the typical BIM Modelling software…Many options are available currently in the industry to integrate construction schedule to BIM Model…Feel free to write to me at email@example.com
35. What is difficulty level of Facade LOD in terms of time and skill?
Façade modelling is typically an efficient process ones the major library items are properly developed with the right parameters. I would say software skill required for façade modelling would be at 8/10
36. Indian clients are prone to change the design very frequently. So we as MEP CONSULTANT to change / revised the drawings more no of times and our man hrs goes into that. Will we able to control on this by using BIM. Just need suggestion
Yes…Few key reasons behind frequent design changes are
• Lack of understanding on the project requirements & goals
• Lack of proper coordination with all team members early in the project
• Overall lack of collaboration across multiple team members both within a single team as well as multiple offices.
Knowing this, BIM primary targets to resolve all the above challenges.
37. In a single project - can we have multiple sub-projects or wrok packages - like - buildings, roads , sewer network , Transmission line etc.
Yes…BIM Models are broken down in multiple files basing on the "File Breakdown Structure" defined early in the process to have Towers, Roads, Sewers, etc. Modelled separately as sub-projects.
38. Can Arbitrator use BIM output for Dispute Resolution
This pretty much depends on the contract terminology documented and agreed upon by two parties. I have seen both scenarios where BIM is used only as a FYI vs. BIM is used as the only accurate representation of the information.
39. Is it the training programs to start with?
The starting point could be training program at the management level as the most effective approach we have seen is "Top Down" where the management decides and formalizes the BIM Implementation roadmap and ensures the functional groups are following up.
