In this blog, we take a look at some of the most common questions about using BIM in civil engineering including its applications in the industry, its various benefits for civil engineers, popular BIM software for civil engineers, and even a list of BIM course suggestions to help you ace this new process. So let’s get started!
What is BIM?
BIM, or Building Information Modelling, is a highly collaborative process that helps digitally construct an accurate virtual model of a building known as a “building information model”. This model can be used for the planning, design, construction, and operation of the facility. It helps the various stakeholders visualise what is to be built in a simulated environment in order to help them identify any potential design, construction, or operational issues.
When completed, the building information model contains precise geometry and relevant data needed to support the design, procurement, fabrication, and construction activities required to realise the project. After completion, this detailed model can be used for operations and maintenance purposes as well.
Advantages of BIM
There are various advantages of using BIM in the design and construction process, including:
1. Cost and resource savings: With BIM, AEC professionals can estimate costs related to materials, material shipping, and labour. Not only does this give architects a better idea about how much the project will cost, but it also helps them discover new ways to reduce costs early on. For example, they can choose more cost-effective materials, etc.
2. Shorter project lifecycle: Generally, the faster you complete a structure’s construction, the less money you will spend on the project.
3. Improve on-site collaboration and communication: The BIM ecosystem allows teams to share project models and coordinate planning. This ensures that all design stakeholders have detailed insight into the project.
4. Sustainability: BIM helps reduce construction waste and report carbon data. This helps in making the buildings and infrastructure projects more sustainable.
5. Transparency: There is an on-going debate that BIM might be the best way to fight corruption. BIM allows for greater transparency during the development stages, thus effectively reducing the likelihood of intentional design errors, false progress reports, and project estimation manipulations occurring.
Why is BIM important?
A recent report from Dodge Data & Analytics found that BIM is rapidly becoming a standard practice throughout the industry. While architecture firms are the fastest to adopt BIM practices, civil engineering firms are also embracing BIM at record levels.
The data above highlights the importance of BIM in civil engineering. The need to learn and understand BIM has never been more urgent in this rapidly digitising AEC industry.
2. What are the applications of BIM in Civil Engineering?
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of infrastructure projects such as roads, bridges, canals, dams, airports, sewage systems, pipelines, and railways. The misconception that many engineers have (because of the acronym “building” in BIM) is that BIM is only useful for architectural projects. But this is far from the truth. Civil engineers can, in fact, avail the benefits of BIM at all stages of an infrastructure project lifecycle. The following are some of the applications of BIM in civil engineering:
Capturing existing site conditions
BIM helps civil engineers start their projects more efficiently, by creating large-scale, intelligent 3D models of their project’s real-world environment. With BIM, they can easily aggregate large amounts of existing data, including reality capture data, 2D CAD, raster data, and GIS (Geographic Information System) data, to enhance the accuracy of the 3D model of existing sites.
Conceptualisation
Using an intelligent 3D project model, civil engineers can rapidly produce conceptual designs of their infrastructure and evaluate different options in preliminary design phases. This helps them transition to a detailed design stage faster by adding greater precision to their design model.
Detailed designing
BIM offers a range of tools for civil engineers for the process of detailed designing. They can use advanced tools such as component roads, cross-section views, and superelevation, for more advanced road design. For transportation projects, BIM tools can be used to effectively design roadway alignments and easily add turn lanes, intersections, and overpasses. Specialised analysis tools are used to check parking lot spacing and road styling to help determine lot counts for better preliminary subdivision layout concepts. BIM also facilitates better planning, design, and structural analysis of bridge structures with the help of expanded bridge design features like component-based bridges and line girder analysis to enhance accuracy and precision.
Performing analysis and simulations
One other use of BIM in civil engineering is that it helps perform analysis and simulations on the 3D models. BIM allows the engineering teams to make better design decisions with tools for sight distance, flood simulation, dynamic site analysis, and more. Some examples of this include:
Coordination and collaboration
BIM helps all the stakeholders involved in a civil engineering project to collaborate on a shared model. This helps them stay engaged in the process, and contractors can use the model to create an informed bid while minimising cost surprises.

Cost Reduction
BIM can be used by civil engineers for model-based cost estimation or 5D BIM. BIM has tools to automate the cost estimation process early in the planning stage, helping save both time and expenses. This helps civil engineers calculate future expenses with much greater accuracy. These include anything from the costs of materials and prefabricated or modular elements to labor and shipping costs. Furthermore, BIM software can help companies optimise their expenses by comparing the cost-effectiveness of different materials, suggesting the best timing to purchase materials at a low market price.
Improved collaboration
Using BIM sets a project up for a controlled, direct data flow between office and field, and design and construction. BIM is a highly collaborative process that allows architects, engineers, real estate developers, contractors, manufacturers, and other construction professionals to plan, design, and construct a structure or building within a single 3D model.
Clash detection
Clash detection is a critical part of the integrated BIM modelling process. The process helps in speeding up projects by identifying clashes between several models during the design stage itself, helping civil engineers eliminate chances of multi-level design changes that can result in budget overshoot and delay of project completion time. Navisworks is the best BIM software in the market, useful for clash detection and clash report generation.
Improving sequencing and scheduling
4D construction sequencing combines 3D models with project programmes, creating an intelligent visual construction timeline. 4D construction sequencing is the best tool for on-site construction for civil engineers. Understanding the construction phase-by-phase timeline and schedule is made easier by this procedure. Better scheduling ultimately leads to better project delivery.

AR / VR
For civil engineers working on infrastructure projects, creating visualisations and walk-throughs with AR/VR can also impact the project delivery and how their current and potential clients perceive their ideas. This can also indirectly impact gaining more work or approvals. After surveying 32 BIM-assisted projects, the Centre for Integrated Facilities Engineering (CIFE) at Stanford University found that the use of BIM technology resulted in:
3. What are the popular BIM software used by civil engineers?
BIM software for civil engineers provides a model-based process for designing and managing buildings and infrastructure, creating a digital representation of the functional characteristics of a facility beyond construction drawings. Some of the popular BIM software used by civil engineers include:
Revit
Autodesk Revit is a building information modelling software for architects, landscapers, structural engineers, mechanical, electrical and plumbing (MEP) engineers, designers, and contractors.
Tekla Structures
The software is used in the construction industry for details of steel and concrete, precast and in-situ casting. The software allows users to create and manage 3D architecture models in concrete or steel and guides them through the process.
Civil 3D
This is a comprehensive detailed design and documentation software for civil infrastructure. Created by Autodesk, it is used to plan, design and deliver land development, water and transportation projects.
Infraworks
InfraWorks is another Autodesk offering that helps civil engineers model and understand infrastructure projects in context. They use it to generate accurate and visually rich conceptual designs and aggregate contextual data from sources like geospatial information systems (GIS) and reality capture.
Navisworks
Used primarily in construction industries to complement 3D design packages (such as Revit, AutoCAD, and MicroStation) Autodesk Navisworks allows users to open and combine 3D models, navigate around them in real-time and review the model using a set of tools including comments, redlining, viewpoint, and measurements.
A selection of plug-ins enhances the package by adding interference detection, 4D time simulation, photorealistic rendering and PDF-like publishing.
