Introduction
BIM for Sustainable Building Design
Firstly, we need to discuss Building Information Modeling (BIM), what it is, and its potential to Conquer the answer to sustainable design. BIM in and of itself; is known as the process to design buildings and structures on a collaborative level. BIM is Allowing Architects, engineers, and the Construction Industry (AEC) to make changes in real time. It can track the amount of time each person spends working on the project, projecting constructio n costs and timing from the beginning of a building; thus, helping construction meet completion goals better than ever before. It also tells the AEC information right down to what, when, and where the building will need to maintenance. That is the simple definition.
Where is BIM going
In truth, BIM goes so much further; it is difficult to take in all that this has to offer. Other than the genius that has gone into its creation. BIM has been a long time in the making and, seems to be a fluid and ever-evolving form, taking shape into things we had not previously imagined. However, as technology grows, our applications and their abilities are ever expanding too. Where is the future of building information modeling going?
The future of BIM
Well, it is going green; as the future of BIM technology changes along with everything else, it is maturing and growing into something that gives AEC some remarkable power in building design. As if this were not enough, the future of BIM software will be able to integrate with other emerging schemas that focus on building green. Moreover, even upcoming AI implementations; which, will streamline the drafting and how information is changed and entered into the BIM even further.
The future of BIM in construction
Which is excellent, mother earth not only needs it, she is begging for it; and so are the people and animal life. Not only is it great that this is being worked on by concerned AEC, but due to The Energy Independence and Security Act of 2007. Requires that new construction and renovation projects must make sure they are using 55% less energy than other commercial buildings. Furthermore, by 2030, all new facilities have to meet the new standard of net-zero energy buildings.
When BIM optimization is applied
Well, there is BIM, and there is, of course, optimization of the tools you have at your fingertips. The BIM is just a thing, without humans that actively utilize BIM and sustainable construction are optimizing it, without AEC using this valuable tool, it is just another program sitting on a desktop. We, just cannot have that. The power of BIM to grow sustainable homes, structures, and buildings is too powerful to let it sit on the shelf; therefore, it cannot!
In today’s world of pollution, BIM software is the future
In today’s world of pollution, greenhouse gases, energy footprints, and more; tools like this are no longer sitting around on the shelf. With the worlds collective environmental problems, particularly climate change, being a severe global issue; just waiting for the bright minds of today, and technology, to concentrate its efforts on solving this sobering challenge. BIM has the power to change all of this when optimized for today’s sustainable construction. The AEC now realizes how vital BIM for sustainable building design. The AEC also recognizes how badly needed such a powerful tool is and can be. Assisting in this global issue, the aims of BIM are leaning more toward sustainable building design. The future of building information modeling is taking many steps to solve these issues.
BIM Optimization for sustainable building design
Imagine it. Green buildings. There is a subset of BIM Optimization for sustainable and greener buildings. Green Building IML is a subset of the BMI modeling efforts. This subset of optimizing BMI and sustainability; thankfully, is a reality. Many people are not concerned at all with the carbon footprint and pollution that buildings create or perhaps, they have never thought of how much additional energy buildings use. Honestly, it is a staggering amount. Our beloved buildings and structures are releasing over 70% of greenhouse gasses emitted. Moreover, they use a crushing 70% of the energy consumed in the United States alone.
The future of BIM technology and solutions
It does not take much thought to realize this is a staggering amount of energy. Also, it is such a large number; it is obnoxious. Moreover, it is an issue for our climate, air quality, and carbon footprint affecting the entire world. Some of these numbers may be in the USA, but we all know the wind blows across the globe. This fact is not only revolting, most of us realize it is causing health issues and climate change; this is where BMI optimization for sustainable construction comes into play. Making crucial correct decisions regarding sustainable buildings at the initial stage plays a pivotal role in realizing the sustainable building. It is clear why in recent years, BIM has become a favorite approach used for sustainable building design.
The future of BIM and theme of sustainable building
The general theme of a sustainable building is: Use as few resources as possible, not to disturb ecosystems, disrupt natural life rhythms during construction, maintenance, operation and demolition of a building. BIM is a favorite approach to the creation of the sustainable building. Giving the AEC the ability to enter all the geometry, geographic information, spatial relationships, and the properties and quantities of the building elements; which, are saved in its virtual 3D environment. Thus, the ability to apply simulation after simulation while still in the virtual environment. Giving them the ability to verify the performance of their designs. Also, giving them the full use of the future of BIM in construction designs, and find one that works best for the build area and environment. The future of BIM technology and its optimization, and more widespread use may be just what the doctor ordered for the planet, and all of her inhabitants. Taking nature, wildlife, and humans into consideration before a build, will decrease not only the carbon footprint and emissions; but the effect the buildings have on our emotions and how we have finally come to value simple things such as clean air, environment, and wildlife habitat erosion.
Conclusion
Of course, these changes cannot happen overnight. However, it creates hope and the possibility of change; that things can and will be better for our lives and the lives of our future generations in general because of the unique technology of building information technology.

Introduction
Like many other countries construction in India is booming to keep pace with the growing need for both urban development and new infrastructures. At the same time technology is moving quickly to assist with these complicated developments with a key player emerging as Building Information Modelling (BIM). This article looks at the benefits of hiring a BIM agency in India and what this could cost to help construction companies consider whether this is the right option for their project.
What benefits are there to using BIM?
#bimncad
In a nutshell, BIM is assisting the AECO industry to reduce delays and costly overruns, implementation of more advanced 5D BIM also can avoid potential litigation. A 3D digital model of the planned construction is produced to allow design issues to be resolved before building even starts; more data can be analysed alongside the model to include scheduling and cost information thus avoiding costly delays dues to clashes as well as expensive reworking, this is 4D BIM. For a complete visualisation of the project, 5D BIM considers cost, schedule and spatial design for the entirety of the project from conception to demolition to everyone involved in the project. Management of ongoing versus target costing particularly helps avoid potential litigation.
Does my project need a BIM agency?
The design stage any project can cost between 5 – 20% of the total budget, but caution should be erred when deciding whether to cut cost in this area, a lower design spend could lead to problems later and incur unexpected construction costs.
Consider also overall savings in this example:
20% of a $200,000 project is to be spent on design or $40,000 seeking a 5% reduction in this saves $2000 but when we think about the larger construction cost of $180,000 of total budget gaining a 5% reduction here would save a huge $9000. Consider whether this is achievable if you have a more robust design.
What varies the cost of BIM agency input?
Some projects require the use of a civil engineer particularly if they are subject to governmental or other regulations. India is no exception in the last ten years the need for qualified civil engineers has grown with the need for construction. Ensure that a civil engineer is used should this is mandatory but consider it for all complicated projects. It is increasingly likely that a civil engineer will recommend the use of BIM technology due to its significant benefits and potential cost saving.
Various factors will affect the cost of BIM agency involvement such as the level of detail (3D, 4D or 5D) you desire or the project demands. Focusing on the project generally the larger the project, the higher the cost but note that more complicated or special projects such as sewage works or dams will have a higher cost regardless of size. The nature of the workforce may also impact cost. Obviously, a larger workforce takes a larger scale of the organisation to ensure scheduling is fit for purpose. But the involvement of numerous contractors such as electrical, water, gas services, plumbing all need coordination, a greater number of contractors may also increase cost.
The experience of the BIM agency is important as is their understanding of local regulations (which vary both from country to country but also in different states). Obviously, more experienced agencies may command a higher fee, but this must be balanced with potential savings this type of knowledge could gain.
Do I need 5D BIM?
The Indian government has made a significant investment to grow the AECO industry, this along with the development of many mega-structures such as the metro train project has increased focus on the use of technologies including BIM.
The amount of detail needed for each project will vary, but it may be desirable to gain more information at this early stage to reduce construction costs but also remember that 5D BIM looks at the entire life of a project. This will factor in such changes as future greenhouse gas emissions, refurbishment and indeed life expectancy before demolition thus managing ongoing costs as well as initial build. This is potentially crucial for the future of the construction industry in India, being able to construct a building at low cost is desirable but delivering a higher quality construction with a longer lifespan and lower ongoing running costs is highly desirable.
What is the potential saving of using a BIM agency?
While cost will vary from company to company, we can assess the impact both on initial costs of construction and over the lifetime of the building by comparing possible savings.
Having an efficient design produced by a BIM agency could reduce conflict and reworking during construction by up to 55% and improve the quality of the finished structure by 50% leading to higher levels of customer satisfaction and giving an extremely desirable reduction of up to 20% in construction cost. Use of BIM can also improve structural performance by up to 35% meaning the lifespan of the buildings will be longer. If we compare savings over time including operational costs with construction costs a 33% reduction of the total anticipated spend is possible.
Using these figures, our previous construction example with an anticipated spend for construction of $200,000, would potentially reduce to $160,000, giving a massive saving of $40,000 in initial costs.
[This is a general example and exact savings would be the result of numerous factors].
Conclusion
Each project needs a careful cost analysis to compare the cost and savings of various factors. The use of BIM technology and hiring a BIM agency in india to do this is certainly an important one to consider as the potential benefits of avoiding delays and reworking to construction will definitely lead to savings. India has a growing construction need which will drive down the cost of BIM agencies and increase the savings for developers.

Why Should Building Information Modeling (BIM) Start from the Early Stages ?
So, what is BIM or Building Information Modeling?The definition of Building Information Modeling or Building Information Model(BIM); describes the process of designing a building on a collaborative level. Thus, using one system of computer models, coherently bringing the design together; rather than many separate sets of drawings. Moreover, a digital representation of the functional and physical characteristics of a facility. It is a resource of shared knowledge or information regarding a facility. This information can be essential to making responsible decisions regarding a facility way to early than from the traditional CAD drawings. Not just from the conception of the building, but during the facilities life cycle too. It is a plan from the conceptualization of the structure to demolition. In short, it is a piece of software(s) that designs the building, from birth to death.
Understanding (BIM) Modeling, helps us see its potential impact. Now, that we understand the definition of Building Information Modeling (BIM) software, let’s look at a few of the advantages BIM software offer.
- Easy visualization of your construction project in a 3D environment.
- Less rework on design changes thereby acting as money saver and time saver,
- Improved collaboration between consultants reducing on-site coordination issues early,
- Various simulations can be performed such as construction sequencing and construction cost providing transparency among shareholders
It is easy to see why starting with BIM or Building Information Modeling in the earliest stages of a construction would be the smart move. BIM allows the stakeholders to bring their construction projects to fruition more seamlessly, and with fewer surprises. Traditionally designing buildings relied mostly on two-dimensional technical drawings. (e.g., sections, elevations, and plans to name a few), recently, the shift to BIM has created more value.
3D (height, width, and depth), and beyond!
With the development of computer programs from old days, there was a considerable innovation of being able to create your buildings in 3D and the old drawing table and tools of the trade of architecture. Drafting on the paper in the digital was only the start. Building Information Modeling(BIM) extends the scope of what the older programs did. Also, taking it the ways beyond 3D as technology kept changing and is changing.
Building information modeling, 3D design software, with a twist.
Not only you have the 3D capabilities as you had in the older and more traditional CAD software, BIM brings time as the fourth dimension, cost as the fifth dimension and has a much broader scope and meaning than just geometry. It carries the manufacturer information for the properties and quantities of building components, and materials used in the completion of the building. BIM is capable of projecting completion time as and when necessary repairs to the structure might expect. From Construction Documentation to Maintenance, everyone working on the project is on the same page and they have access to, and can enter data into the BIM, which is essential to a seamless outcome.
(BIM) modeling services can build from the ground up.
The BIM modeling program or services first starts from the ground underneath the structure. The project begins with the images of the earth, digital elevation, and aerial imagery, along with laser scans of the existing site. BIM is capable of capturing real-time information in regard with the project location. BIM Designers benefit from all the input compiled and shared in a way paper was never able to do.
Imagine you need to make changes to your project, now what? 
There was a time when, if there were changes in a plan (e.g., number of size of windows) for some reason, an entirely new drawing had to be redraw to account for the differences. Maybe just to add a staircase or another exit. Now, while using BIM, you make the changes, hit save, and the whole team has access to the new information in real time using cloud technology. Instead of heading back to the drawing table, and starting again, adding and taking elements away has become a thing of ease now. Think of the money saved by an action to just save the project, thus helping everyone to stay on the same page while working on the construction project; this is one of the more luxurious aspects of Building information modeling. It will also link construction cost and installation costs for the newly added attributes to the building. Thus, saving time and significantly reducing the overall cost of the building project.
Building Information Modeling(BIM) programs and the environment.
BIM modeling can also take the overall operational costs of the finished product in mind. It also has multiple simulation options available so that the design staff can observe the building attributes in all seasons. Its features such as this that can assist in building smarter, more economical, and energy efficient structures. With the click of a button, all the analyses can be done to achieve peak performance. Building Information Modeling(BIM) programs can also detect potentially costly errors on the construction site and can inform about its occurrence such as on-site coordination issues. Things such as electrical conduits or ducts that runs into beams on site; this on-site issue can be expensive, and can be effectively bypassed with BIM modeling. The problem will be detected before you break ground to construction. BIM has the ability to fix such issues, such as these on-site coordination issues, that often plague projects when run by multiple teams. Here again, BIM is a money saver for construction projects. Also, BIM is an excellent way for the transfer of knowledge by sharing traditional plans, sections, elevations, as well as other types of reports that the teams can share with other parts of the project team. The software has customizable features and automation tools such as annotating a category of elements at once, saves precious drafting time; thus, conserving the project money and construction pitfalls.
BIM modeling software helps sequence the steps in a building plan.
BIM modeling software can sequence the steps of building the structure and all phases of these steps, down to the materials needed to accomplish the next step in the series of construction. The sequencing of steps is completed with animations and simulations, helping to coordinate the construction processes. Hence, delivering a more predictable outcome of the project beneficial for stakeholders. These are just some of the reasons that if a BIM plan is in place and is wisely used in the earlier on in the project, the better or smoother the project progresses. Making projects more seamless while saving valuable time and money on any project from a home to a high-rise building.

Global BIM (Building Information Modeling) scenario
In the construction industry, traditional methods (2D) for design and construction is being rapidly moving towards 3D digital models: BIM. Developing intelligent 3D digital models and communicating project information with ease within the project team is the key within BIM.
The current BIM Adoption in India in building industry began by the similar approach as the decades-long usage of digital prototyping by the manufacturing industry for engineering, analysis, and production of products.
In today’s scenario, as the economies are rebounding at a snail pace, the building supply chain ranging from architects, engineers, contractors, and fabricators are expected to deliver projects faster and within smaller budgets. To gain the competitive edge, more and more firms are adopting BIM which improves productivity and profit margins which have resulted in many BIM mandates across various countries.
Expectations are growing for closer collaboration of different disciplines within the project. Advancement in technologies for communication and cloud technologies has transformed how people work together.
Prefabrication has witnessed increased demand by improving construction productivity and BIM work-flow bridges design and construction by connecting designers with fabricators and contractors.
Economic construction with clear design intents has become the expected standard for building projects in today’s world. BIM work-flows and analysis tools help firms evaluating the cost-effective project delivery at every stage.
Therefore, rapid BIM adoption in India in the construction industry has clearly highlighted that the industry is moving away from the traditional 2D methods towards BIM for fast and cost-effective project delivery.
Can we still rely on decade-old 2D process and technology to survive?
Before answering this question, let’s closely look at what is BIM.
It’s the question the majority of us from the Architecture, and Construction background must know. BIM is a way to create the digital model of the building or infrastructure before its actual construction. Note that the digital model must be intelligent enough to provide various information such as visualization, documentation, cost estimation, clashes, simulation, etc.
BIM tools such as Autodesk Revit works on integrated databases to maintain relationships between different model elements by connecting everything. Additional efforts are none to keep the project data in sync and manual labor is less.
Professionals practicing BIM has experienced reduced errors and omissions, reduced project duration, more profit, win new projects, repeat business, etc as short and long-term BIM benefits.
To survive in the upcoming times, firms must re-work on their strategies by adding the use of BIM. One cannot sit back and wait for the increased BIM Adoption in India in their business markets. They need to be at the forefront of using BIM.

Building Information Modelling (BIM) has become one of the most promising developments in the architecture, engineering, and construction (AEC) industries, and fundamentally it is changing the way the construction industry works. In recent years, the industry has shifted from traditional two-dimensional drawings, drafts, and designs to 3D visualizations. And worldwide has adopted the BIM concepts and technologies of Building Information Modelling and there is an upward demand for the digitalization of the existing building stock.
“Scan to BIM Services (popularly known as Point Cloud to BIM) referred to the process of 3D laser scanning a physical space or site, to create an accurate digital point cloud of the structure and using scans BEM software, bridge the gap between a separate digital point cloud and one that can be used inside the Autodesk Revit platform. That representation can then be used for designing, assessing progress or evaluation options.”
Scan to BIM is a technology that came as a breakthrough in the construction industries as it is accelerating rapidly as it provides a faster, captures dimensions, volume quickly, efficiently, a highly detailed and accurate structural profile for capturing survey data critical for refurbishment or retro-fitting existing projects.
Point clouds resulting from scan data are massively powerful for analysis on their own. Converting scan data into BIM models is customarily a three-step process: First, from different scanning stations, multiple scans are captured from. Second, data from multiple scanning stations is stitched together in what is commonly known as the post-processing or registration stage. Next, CAD or BIM software can be used to author object models while referencing the point cloud.
It is clear that Scan to BIM is the future of AEC industry and produces high definition scanning has practical, time (faster than 2D drawings) and cost-saving applications especially at the initial stages of repositioning projects and increase the accuracy of project information.
