From pencil to paper and 3D, 4D, or even 5D BIM— there’s no doubt things are rapidly changing in the construction industry. CAD is transforming the way we work – and will continue in the future.
Computer technology has offered both design and manufacturing industries many advantages when it comes to managing processes and concentrating efforts on increasing overall efficiency and productivity. A lot of time previously spent on lengthy design and correction processes by hand, has been saved by the introduction of Computer Aided Design.
The introduction of Computer Aided Design (CAD) has led to an increase in productivity all over the world. CAD is the use of computer technology to help design a product and contains all the activities of a design process. This makes it possible to develop a concept idea into a product to be manufactured, including all the associated specifications. Engineers use CAD software to increase design productivity, improve design quality, improve communication through documentation and create a database for production.
Within CAD, a distinction is made between three systems:
The step after 3D systems is BIM (Building Information Modelling), which has attracted a great deal of attention in recent years. However, the concept of BIM is actually not new and dates 30 years back, while the term BIM itself has been in circulation for approximately 15 years.
The first document to describe a concept now known as BIM was Charles M. Eastman’s description of a working prototype Building Description System, published in the AIA Journal in 1975. This was the first time that interactively defined elements were used, where information on matters like floor plan, facade, perspective, and section was contained in the same description of an element. All changes only needed to be made once, as modifications in all other drawings would happen accordingly. Data on costs, quantities and materials could easily be generated.
The first time the term Building Modeling was used as we know it, was in an article by Robert Aish in 1986. Aish stated that in order for CAD to be effective in multidisciplinary teams, information should be represented in an appropriate way, for example in a 3D view. He coined that an integrated CAD system could be a solution to facilitate the coordination and consistency of design information.
From Building Modeling, it was just a small step to Building Information Model or BIM, which was used for the first time in a piece ‘Automation in Construction‘ from 1992 by G.A. van Nederveen and F. Tolman. This paper presented an approach in which aspect models from different participants in a building project together made up a building reference model.
Today, BIM is described as a working method in which a 3D Building Information Model (BIM) integrates the collaboration of various disciplines in the construction industry.
The standardization committee of the American National BIM Standard describes BIM as:
“Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition.”
So a BIM model as we know it today is a resource to be used throughout the construction process: from first design, during construction, during management and operation to the demolition of the building.
Across the world, BIM adoption and standards vary but the fact that BIM is transforming the way we work in construction rings true everywhere. While some firms are taking the first steps from 2D to 3D design, others are already taking the step from 3D to 4D, 5D or even 6D BIM:
The use of CAD has grown strongly over the years and has changed radically – and will continue to do so over time. The most important aspects of future CAD technologies and software will be convenience and speed. The design process should ultimately be made faster, more efficient and easier.
With generative design, these 3 objectives can be achieved.
Generative design software uses the design objectives and parameters entered, such as material, construction or manufacturing method and costs, and the computing power of the cloud. Based on the objectives and parameters, the cloud computing power generates several design options. These options can be very complex: it would take days or weeks to devise and develop them yourself in the3D CAD software that’s currently available. And, thanks to 3D printing technology, it will be possible to actually produce such complex design options.
Generative design will shift the role of designers, engineers, and modelers. From using the computer as a drawing tool, engineers will co-create with technology and focus on setting goals and criteria. Ultimately, determining the best design will be left to technology.

Overview
Building Information Modeling (BIM) brings many benefits to the construction industry due to which it is largely accepted worldwide and adopted by many countries. In 1986, the term BIM came into existence, and since then it is transforming the construction industry. Countries that are majorly using BIM Modeling have a rich site in the infrastructure phase which in turn helps to bring improvements in productivity and cost-savings to all the AEC industry.
Countries who have adopted BIM
United Kingdom
The UK aims to enhance the mindset practice of all the designers, contractors and engineers to obtain new work and growth opportunities. BIM gets mandated in the UK since April 2016 where every construction and the entire government project are held on BIM Level 2. According to the National BIM Report 2018 NBS, After BIM mandatory 20% of industry have started adopting it successfully and attained a 12% increase since 2017. BIM is implemented prevalently everywhere in all the projects.
United States
BIM implemented in the United States since the early 1970s but being the early adopter, it didn’t gain the United States any advantages and instead the process of using BIM has slowed down. United States Government has still not thought of making BIM mandatory. The US General Services Administration (GSA) prepared 3D and 4D BIM Program way back in 2003. This program got BIM adoption mandated for all the Public Buildings Service Projects. Wisconsin was the first state from the United States who has implemented BIM for public works with a budget of $5 million. Gradually BIM adoption is increasing its awareness in the United States and has positively impacted on the AEC industry. United States holds 72% of BIM adoption by the construction Companies.
Singapore
BIM is identified as the core element for Singapore to become the smartest nation Construction, and Real Estate Network, or CORENET, the Building & Construction Authority have implemented the use of BIM e-submission in the construction industry, making it mandatory in 2015 for all the projects greater than 5000 Sq. Mts. In recent years, the government of Singapore has showcased productivity in the construction industry due to which BIM adoption has been seen as strategic actions. The BCA came up with BIM collaboration roadmap throughout virtual design and construction which facilities the use of BIM for Facility Management and Smart Nation.
France
In 2014, The French government developed BIM standards for infrastructure projects along with using BIM to make 5, 00,000 houses by 2017. The government had allocated Euro 20 million to digitalize the building industry due to which in the nearer future BIM will be mandatory in public procurement. For the construction industry in France, the government has taken the initiative as Digital Transition Plan which aimed at achieving sustainability and reduces costs, since after this in 2017 BIM gets mandated in France.
Germany
Around 90% of owners are demanding to use BIM and laid its emphasis on the commercial and the residential buildings. The German government still relies on the conventional method used by the AEC industry which has not fully accepted BIM adoption and for which in 2015 government announced Digital Building Platform plan to be developed. It is believed that by 2020 BIM will be mandatory for public infrastructure projects.
China
In 2001, BIM implementation in China had been in the discussion by the Ministry of Construction, Ministry of Housing and Urban-rural Development. According to a survey conducted, it was concluded that less than 15% of companies were using BIM. MOHURD in its 12th Five-Year Plan proposed a plan for improvisation work in the construction industry and said that BIM is not mandating to use. National standard of BIM practices has begun and approved by the Ministry of Science and Technology of China. By the end of 2020, BIM will be used effectively more by construction firms. In 2009, Hong Kong Building Information Modeling (HKBIM) was incorporated. Many government authorities have started focusing on UK Level 2 Standards and give training for the same.
Scandinavia
Norway, Denmark, Finland, and Sweden have been the early adopters of BIM technologies. Finland had implemented BIM technology since 2002 and by 2007 Finland mandated that all the design software must be verified with Industry Foundation Class (IFC) Certification. IFC is a file format that can be used for shared models and can work independently on any piece of design software.
In Denmark, BIM mandated its state clients, Palace and Properties Agency, Defence Construction Service to adopt BIM practices while several private firms are working on Research and Development for BIM adoption practices.
Sweden ranks high in BIM adoption practices, and best practices guides for the same have already been published even in the absence of government-led guidelines. The government also has taken initiatives to facilitate its implementation and public organization to mandate the use of BIM in 2015.
The civil state client Statsbygg and Norwegian Homebuilders Association have promoted the use of BIM. All the civil state client projects used IFC formats and BIM for constructing the buildings during 2010. SINTEF has conducted thorough research on BIM to improve the construction and operations of the buildings.
Australia
Many private sectors, as well as business owners, have started adopting BIM at faster rates. For all the public areas, a standard like PAS1192-2 is used for the adoption of BIM due to lack of skill and work in isolation makes it crumble for the adoption of BIM in Australia. No proper methodology is developed here to measure the level of maturity. Support and Guidance are asked from the United States to initiate BIM adoption practices well in Australia.
Europe
BIM implementation is showing good progress in Europe. BIM adoption is successfully done by Companies, Academics, Professionals, and government institutions. Standard BIM practices and digitalization in the industry is a must and can bring huge success for Europe’s overall construction industry. Europe BIM task group in 2016 was established to develop a digital construction sector and has brought progressive impacts on adoption of BIM in the country.
Canada
BIM adoption in Canada is still at the existence stage with around 31% of the Canadian industry using BIM. No federal government has mandated BIM in the country yet but in the near future can increase the adoption of the use of BIM. Canada’s infrastructure industry can change its recent conditions by mandating BIM and its standards. In 2004, building SMART Canada started increasing the activities of using BIM for all construction projects. By 2010 Council by Institute of BIM in Canada (IBC) was formed to lead and facilitate the use of BIM in the construction industry.
India
The second largest industry in India is AECO (Architecture, Engineering, Construction, and operations). Gradually with all its efforts are focusing its shift to BIM. It can be very cost-saving technology and effective for India, but we are still on the design implementation level. Private Sector has started using BIM standards for Nagpur rail project which had used the 5D BIM technology to take it to another level of the project in the whole construction industry. BIM technologies such as BIM Co-ordination and Clash Detection processes would be used to enhance the construction quality, reduction in cost and greater efficiency in the project. With a growing economy and understanding of BIM in the construction industry, the entire practitioners involved can effectively adopt BIM.
Conclusion
Every country must include effective use of BIM in their construction projects for achieving many benefits such as reduced costs, time and efficiency. Every part of the world have readily accepted BIM standards and started its practices. It helps to replace the conventional methods of construction industry worldwide. Many updates in BIM technology can help them communicate their design more realistic and better approach that can even work on the sustainability of energy consumption in the near future.

Building construction tools make everyone visualize hard hats, hammers and heavy machinery. It is a pity that no one thinks of technology, 3D modeling, expert BIM consultants etc., which ideally should be the case. Think of a construction project with no or minimal clashes, improved collaboration and coordination, reduced risk and increased cost savings that Revit software brought to the final delivery. That is BIM Implementation. But if all this was about BIM, what is BIM execution plan?
BIM execution plan, also known as BEP or BxP, is very critical for any new construction project and all three architecture, structural and MEP disciplines. The development of such a plan, for facilitating the management of information in any BIM project, is set out in PAS 1192-2:2013 as a direct response to the Employer’s Information Requirements (EIR).
Benefits of using a BIM execution plan for building construction projects:
Instant and accurate communication among teams from the inception of any construction project is what BIM execution plans encourage. It helps all involved to manage responsibilities and expectations. It also ensures clear communication is available to all stakeholders across the construction project.
Every construction project tends to differ from the previous one. It may have different requirements in and around the needs of internal standards, regulations and the overall project. Because the BIM execution plan is in place and active, the project team is required to collaborate in real time across construction project phases. This prevents unnecessary silos among project tasks and warrants that adequate attention is paid to a particular project, irrespective of the requirement or standards in place.
Squeezed time schedules is one of the biggest challenge any and every construction project faces. However; a finely developed BEP with complete focus on project benefits, ensures that none of those involved in the project are overloaded with work, causing damaging delays to the project deliverables. Also BEP sees to it that only the most important details are worked upon and made available in the plan. It further helps in maintaining the schedule of deliverables across the project.
BIM execution plan’s value addition in terms of transparency is commendable. They are conveniently available and accessible to all team members from the very start of the process. From contractors to project owners and many more, everyone has direct access to BIM implementation data including file formats, details and dimensions of the model.
BEP is all about staying focused on the project at hand, and not including every possible standard that exists. It empowers the team to communicate and collaborate better from the very beginning of the project. It promises strong execution and successful finish, pleasing project owners and investors. Executing this plan keeps items on the “to do list” moving which further assures project completion on time and within budgets.
BIM execution plan can be considered to be the rule book for a construction project, where rules in the book tend to change on project to project basis. BEP will enlist the roles and responsibilities of all involved in a construction project. The BEP will also showcase project milestones to the regulations to be adhered to, and the details involving the supply chain, procedures, technology to be used, and a whole lot more.
A contract once is awarded, warrants secondary BEP to be created by the prospective supplier, which focuses on the approach, capability, capacity and competence to meet the EIR in general terms. It details the project deliverables stipulated by the contract and the information exchange requirements, such as the CIC BIM Protocol (a supplementary legal agreement that is incorporated into construction and professional services contracts via a simple amendment), detailed in a BIM protocol.
BEP is created pre-contract & post-contract, so how are they different?
Once the contract is awarded, the winning supplier is required to submit a further BIM Execution plan, which is mainly focused on supply chain capabilities. MIDP or master delivery plan is also required to be submitted at the time of project information preparation. It includes details as to who is responsible for preparing the information and which all protocols and procedures will be utilized to develop the information.
The information to be prepared and included is based on a series of individual task information delivery plans (TIDP) that shows who is responsible for each information deliverable.
With multiple suppliers in a single contract, who is responsible for BEP?
Usually in scenarios where there is more than one supplier in a construction project, there is one main BIM Execution Plan that comprises of the responsibility for its production set out in appointment documents. Subsequent BEPs from the suppliers appointed later, dovetail with the existing main BIM execution plan.
Building execution plan, details working procedure
Every single procedure from how will BIM volumes be managed and maintained to what file name conventions will be adopted, and what construction tolerances are set and what attribute data is required; successful BEP encompasses everything.
Next is to determine what software will be used, what data formats will be used for exchange and what other data management systems will be brought into play. To the extent that in order to avoid potential ambiguity, a common approach to annotation, abbreviations and symbols is charted out. And all this leads to stronger executions, better timelines and happier project owners.
Every construction is different and requires a different BIM Execution Plan; but by properly implementing a BEP, your project has a far greater chance of being successful.
