We often hear the phrase "a worker is only as good as his tools," which certainly holds true in modern construction. Industry standards are constantly changing, so to keep up with the competition, construction contractors must continually look for innovative tools to boost efficiency before, during and after construction. One such tool is Building Information Modeling (BIM).

Understanding BIM tools: a primer for contractors

In a literal sense, BIM tools are advanced software programs for creating and managing project-related information. However, due to their efficiency potential, they also represent a technology-driven shift in the way modern construction is carried out. When implemented from the beginning phases of a project, BIM tools can provide contractors with the groundwork for a modern building method that promotes clear communication and minimizes errors.

How does BIM work?

BIM's primary functionality revolves around turning data into intelligent digital 3D Models. These models serve a dual purpose. Firstly, they provide all project stakeholders with easily understood virtual representations of project components that apply specifically to each trade discipline. For example, plumbing, electrical and mechanical systems within a BIM model can be isolated and manipulated to give contractors a better understanding of how they fit into the overall design of the building.

Secondly, BIM models act as a database for pertinent project details. As a building is designed, developed and built, data can be continually added to the model, giving contractors access to the information they need to purchase materials and calculate costs. 

Key features of BIM tools for commercial installations

BIM tools like Autodesk Revit house an expansive library of features specifically designed to streamline the planning and execution of commercial construction projects. These features have proven to improve precision, reduce project duration and lower overall costs. Here are a few of the many powerful features found within a BIM user interface.

3D modeling and building documents

As previously mentioned, BIM's functionality is centered around 3D modeling. A dynamic digital representation of the building allows stakeholders to conceptualize ideas that would otherwise only be visible after a project is complete. However, for contractors, one of BIM's most significant features is its ability to automatically generate building documents based on data taken from 3D models. In many cases, this feature eliminates 2D drafting from the project development phase.

Cloud collaboration

Commercial contractors are just some of the many individuals who need access to current versions of BIM data. Engineers, architects, project managers and many others depend on up-to-date information to execute their project tasks efficiently. With cloud-based BIM software, all approved stakeholders can access and modify BIM documents in real-time, reducing the time wasted waiting for updated documents.

Clash detection

BIM's cloud collaboration features allow different trade engineers to work simultaneously on the same commercial project. However, from time to time, different building systems interfere with one another. For example, plumbing and electrical engineers may unknowingly design their pipes and conduits to occupy the same space within a wall. Under normal circumstances, this situation would call for a redesign for one or both trade disciplines. Fortunately, BIM is designed to prevent such interferences. Most BIM software is equipped with clash detection features that identify this type of error and prevent users from proceeding with their work until the issue is resolved. 

Real-time data collection

With sustainable building practices becoming increasingly mainstream, contractors need to gather as much data as possible from a construction site to ensure that modern standards are being met. With BIM, data collection is automated as it facilitates the Internet of Things (IoT) concept. 

IoT refers to a network of physical devices, in this case, sensors placed on-site that monitor project aspects such as construction traffic, water usage and energy consumption. Once gathered, this data is fed back to BIM software in real-time to be used by engineers, contractors, and project managers. 

Real-world examples of BIM in commercial installations

BIM's practical benefits are clearly demonstrated in groundbreaking projects like The Edge in Amsterdam and the Barangaroo South development in Sydney. Both projects showcase how BIM can be woven into all phases of a building's lifecycle to enhance sustainability, efficiency and safety.
