With over 20 years of experience in the industry, we have adapted and evolved alongside the expansion of BIM (Building Information Management). This has meant we can address the accelerating demands to meet the future needs of our clients and put an end to their pinch points.
For those who are curious about the world of BIM and want to learn more, we have gathered the top 10 questions which pop up all the time.
Building Information Modelling (BIM) continues to grow and will soon be the future of the Architectural, Engineering, and Construction (AEC) sector. It is transforming the way we do construction from design to the production of architectural and engineering drawings and documentation. It is also used for analysis, costing, purchasing, construction, monitoring, and facilities management.
If you distil it down to its essence, BIM is an information exchange, communication, and collaborative process. The future of BIM involves using the digital model at all stages of a project – from project concept right through to handover and facilities management. The ultimate goal of BIM is to have a digital twin of the ‘As Built’. The proper use of BIM throughout an entire project life-cycle will result in significant value and return on that investment.
At various stages of the BIM cycle/process, the digital model will also evolve in terms of Level of Detail (LOD) and Level of Information (LOI). Combining the geometric aspect of BIM with the LOI within the digital model is the holy grail of BIM. When executed correctly, this leads to swifter decision-making from very early concept design stages right through a project life-cycle, resulting in significant time and cost savings.
There are currently 7 Ds (dimensions) of BIM that are used throughout the life-cycle of a project, but AEC professionals recognise them from 3D BIM onwards.
The 7D’s of BIM include:
The dimensions apply to all roles within a project and can support decision-making in architecture (3D, 5D, 6D, 7D), quantity surveying (5D, 6D), and project management (3D, 4D, 5D). You may also come across mentions of 8D (safety), 9D (lean construction and waste reduction), or even 10D (industrialisation and prefabrication) in industry discussions. These additional dimensions are not yet standardised globally, and their definitions can vary depending on the source.
BIM will touch and affect everyone and every business dealing with design, construction, manufacturing, facilities management, and building ownership. It is leading to changes in processes and procedures, as well as cost savings throughout the entire design, build, and management phases of a project.
Adopting BIM across the AEC sector can significantly improve the delivery and performance of projects, whilst providing a consistent approach that promotes collaboration and innovation.
BIM processes have helped deliver benefits such as monitoring, safety, planning, cost, and more. It has the potential to deliver further benefits in the operations of smaller enterprises by establishing standardisation and asset libraries that can be used across design teams.
The main benefits of BIM are:
The integration of BIM with artificial intelligence, cloud computing, and automation is one of the most significant trends shaping the AEC industry. AI is increasingly used to automate modelling workflows, optimise design performance, and support predictive analysis for cost, constructability, and environmental performance. These intelligent BIM models can be analysed and tested early in the design process, allowing project teams to make better-informed decisions and reduce risk before construction begins.
Another key trend is the shift toward cloud-based BIM platforms that support the full lifecycle of a building, from design and coordination to construction and operation. Platforms such as Autodesk Construction Cloud allow teams to collaborate in real time, unify multidisciplinary data, and manage project information within a single environment. Coordination tools such as Navisworks remain important for clash detection and simulation, but are now part of a broader connected ecosystem. This lifecycle-based approach improves efficiency, enhances collaboration, and supports the development of digital twins for long-term asset management.
Unfortunately, there is no such thing as a BIM architect, as BIM is a process, not a tool. You are either in an environment where the process is used, or you are not.
Many AEC professionals work in collaboration to feed into the BIM process. For architects, they should have a deep knowledge of BIM enabling software such as Autodesk Revit or Graphisoft’s ArchiCAD to develop an integrated model of a design. Various aspects of architectural design, such as structure, mechanics, electrical, HVAC, horticulture, etc can be linked together to develop a cohesive model.
There is a growing number of Applied Building Information Modelling courses becoming available in universities and institutes across the world. These courses are targeted towards AEC professionals such as architects, engineers, surveyors, technologists, and construction managers. These courses enable AEC professionals to work within a multidisciplinary, collaborative design and management process based on international standards.
BIM Modeller/Engineer/Technicians: Create detailed digital 3D models using software such as Autodesk Revit or ArchiCAD. They will work closely with their project architect, creating the model from sketch designs from the early concept stage. However, sometimes this professional will be required to create 3D models from third-party files such as CAD drawings, elevations, etc., which is against the grain of BIM, as 2D data should be pulled from the 3D model. BIM modellers also liaise with design team members to provide project coordination documentation.
BIM Coordinators: Are responsible for handling a team of BIM Modellers and handling the process for interdisciplinary coordination among Architecture, Structure, Mechanical, Electrical, etc. They will distribute work among the modellers, will do linking, managing, supervising, and guiding the team members/modellers about the process. They will generate clash reports and submit them to all stakeholders for further coordination.
BIM Manager: They will be responsible for developing BIM strategy documents, i.e., BIP/BEP (BIM Implementation Plan and BIM Execution Plan). They will lead the coordination process, define the protocols and processes and will be overall in charge of making the BIM adoption a successful process.
BIM Information Manager: They unite the digital model, validating the data and producing COBie outputs at each RIBA stage. They ensure that the right data, in the right format, is delivered at the right time. They validate data at the point of delivery, ensuring that it is correct and in context, as important decisions are made based on its integrity.
BIM (Building Information Modelling) is no longer a luxury but rather a necessity for small architectural firms. The advantages of using the BIM process on large-scale projects are well-documented, but it also has significant benefits for smaller projects and for winning tenders. For architects who are yet to embark on their BIM journey, they can outsource their projects to third-party BIM service providers.
Here are four reasons why BIM for small architectural firms is a distinct advantage:
Accurate Conceptual Ideas: With BIM and 3D architectural software, it is easy to quickly create a 3D massing model of the initial design concept and overlay it onto accurate site data. This gives the clients a better understanding of the proposed design and allows any adjustments to be made early on before too much time has been spent on the project. It also allows for early assessments, such as daylight and sunlight (6D BIM).
Competitive Edge: BIM offers smaller firms a level playing field – more efficient designs using the most up-to-date technology, allowing them to future-proof their business.
Faster Design Changes: Without BIM, updating plans, roof plans, sections, elevations, and specifications is extremely time-consuming. But with BIM and 3D modelling software, the drawings are derived from the model and updated as the model changes, making updates a simple case of changing the model and regenerating the drawings.
Precise Construction: With BIM, designs are more accurate, which leads to fewer unforeseen issues during construction. Also, construction costs and programs can be more accurately predicted through BIM, giving clients confidence that projects will be delivered on time and to budget.
There is a growing number of career opportunities involving BIM, with the continued surge in the adoption of this process across various industries
Whilst we tend to think about designers and architects first when discussing BIM, the actual BIM workflow ties together different fields at every stage of the project and even beyond. These industries include:
Architecture: BIM enables them to make better design decisions, improve building performance, and collaborate more effectively throughout the project lifecycle.
Civil engineering: Can use BIM for intelligent, connected workflows to help improve predictability, productivity, and profitability.
Construction: Digitise their construction sites and connect project information from design through construction and handover.
MEP: Improve MEP (mechanical, electrical, and plumbing) design quality and collaborate in real time to support the project delivery process.
Plant: Manage the design and construction of intelligent piping, structures, and processes more efficiently and collaboratively throughout the project lifecycle and at hand-off.
Structural engineering: BIM allows them to explore how structural design and detailing software help to win new business and support project delivery.
The Building Information Modelling (BIM) market has expanded significantly in recent years as the AEC industry has prioritised digital collaboration, efficiency, and better project outcomes. Market forecasts published in the early 2020s projected strong growth for BIM, reflecting increased adoption across both buildings and infrastructure, as well as rising demand for data-rich project delivery. The drivers below outline what has most strongly contributed to this growth over that period:
BIM Construction Fuelling Market Growth
Due to rising trends in digitisation across all industries, BIM is continuing to gain widespread adoption in the construction industry. Building applications mainly include commercial, residential, healthcare, and retail buildings. However, infrastructure projects have also adopted BIM and are implementing it very successfully (E.g. Shanghai Tower High-rise sustainable design).
Buildings are designed with BIM from the early concept design stage right through the construction phase and up to handover. The benefit of BIM is to have a ‘digital twin’ of the finished development to be used for facilities management. (BIM Design Model – BIM Construction Model – BIM as a Built Model – BIM Facilities Management Model)
BIM Application Accelerated by COVID-19
The COVID-19 pandemic forced the AEC sector to find safer and smarter ways of constructing buildings. During worldwide lockdowns, BIM facilitated the continuation of projects within the digital and virtual environment, even when participants were unable to meet in person. Whilst BIM has always been a collaborative process, this was accelerated due to COVID-19. BIM processes allowed data to be shared remotely across professional disciplines and facilitate smarter construction.
Strong Government Support for Making BIM Mandatory
Government policy and public procurement have been a major driver of BIM adoption in recent years. In the UK, BIM has long been required on centrally procured public projects, and this has continued to shape how design teams structure information and collaboration. In Ireland, public sector bodies have also been progressing BIM adoption through national guidance and phased implementation across capital projects. More broadly, many governments now align BIM expectations with ISO 19650 information management standards, although requirements still vary by client and project type.
Key Players Driving Growth in the BIM Industry
The building information modelling market is highly competitive owing to the many small and large vendors providing solutions in the domestic and international markets. According to Market and Markets, “The industry appears to be concentrated on moving towards the fragmented stage with the emergence of new players in the market. Major players in the market are adopting strategies like product & service innovation and mergers & acquisitions.”
Some of the key software players profiled in the Building Information Modelling Market include Archidata Inc, Asite Solutions, Autodesk Inc, Aveva Group Plc, Beck Technology Ltd, Bentley Systems, Cadsoft Corporation, Dassault Systèmes, Hexagon AB, Nemetschek SE, Pentagon Solution Ltd, RIB Software SE, Synchro Software Ltd, Tekla Corporation and Trimble Ltd.
The strategic roadmap for the BIM industry has four levels. Each level represents the extent of collaboration and the application of digitisation to a construction or infrastructure project.
BIM Level 0: This means a complete non-existent collaboration between stakeholders, and projects will only use 2D CAD drafting. Distribution is either paper-based or electronic (or both). This BIM level is pretty much obsolete today.
BIM Level 1: Represents partial collaboration between stakeholders and design teams. Projects at this level use a mixture of 2D and 3D CAD drafting. Typically, information is shared digitally using a common data environment (CDE), managed by the principal contractor, and shared among team members. Projects may also use some standard data structures.
BIM Level 2: Projects are fully collaborative, with stakeholders using detailed 3D models in a sophisticated BIM environment. In this instance, all parties working on a project can combine their BIM and design data to work together and share information through a CDE. The CDE enables users to carry out regular checks against data validation strategies to ensure the project stays on track. One indicator of maturity for BIM Level 2 projects is the inclusion of a 4D BIM (Project Scheduling), which enables the planning of construction sequences. Another is 5D BIM (Cost Analysis) for improved cost management.
BIM Level 3: This means full collaboration and full integration among all disciplines and stakeholders. They are using a single, shared project view for data integration, which all parties can access and modify as defined through process and security controls. Projects at this level can also have dedicated project streams that inform 7D BIM (Facility Management). In effect, a 6D model enables improved asset management for the complete lifecycle of a building.
The UK officially mandated collaborative BIM on centrally procured public projects in 2016, and this has since evolved into the UK BIM Framework aligned with ISO 19650 information management standards. This framework continues to shape digital delivery across public sector projects. In Germany, BIM became mandatory for federal infrastructure and public procurement projects from 2021, as part of a national strategy to digitalise construction. These initiatives reflect wider government efforts to improve efficiency, coordination, and lifecycle management through digital construction methods.
The future of BIM will be shaped by deeper integration with emerging digital technologies and more advanced use of project data throughout the building lifecycle. Artificial intelligence and automation are expected to play a greater role in supporting design optimisation, clash detection, and predictive analysis. At the same time, BIM models will increasingly form the foundation for digital twins, allowing building performance to be monitored and managed in real time. The continued growth of cloud-based platforms will also make collaboration more seamless, enabling multidisciplinary teams to work on shared models from anywhere.
National governments and industry bodies will continue to expand BIM standards and requirements to support digital construction. International frameworks such as ISO 19650 are helping to standardise how information is created, managed, and exchanged across projects. As adoption increases across both public and private sectors, BIM will become more closely integrated with reality capture, sustainability analysis, and asset management systems, reinforcing its role as a central tool for planning, delivering, and operating buildings more efficiently.
