The continuing march of technology in the modern age has impacted the construction industry in many more ways than meets the eye. For an industry that hasn’t seen significant technological change over the past couple of decades, the arrival of ‘Constructible BIM’ is no less than a revolution.
Earlier, constructing a building required numerous blueprints and models that had to be exchanged between multiple designers, engineers and contractors, where even small edits in design had to be manually adjusted in every plan and the slightest discrepancy could lead to considerable financial loss. Today, however, it has become easy to eliminate themany layers of interventions by providing a single building information model (BIM) for the entire lifecycle of a project—from design to construction to the building’s operations.
Constructible BIM at work
Constructible BIM enables the creation and management of accurate, detailed, highly constructible 3D structural models, regardless of material or structural complexity. It also allows the complete visualisation of a project right from the conception to the end of the project. Building Information Modelling or BIM, as this process as often referred to, is a must for engineers and contractors to be able to make them competitive, credible and differentiated.
The traditional scope of BIM is fast giving way to the significantly more advanced concept of ‘Constructible BIM’ with an eye on the need to address growing complexity in building design and construction. The term ‘constructible’ defines the ease and efficiency with which structures can be constructed from a 3D model. If a BIM model is accurate and detailed enough, the constructability of a building can be tested in advance to make sure that errors, rework, wastage etc, is minimised and the project is predictably profitable.
However, it is important to underline that while all constructible models are BIM-complaint, not all BIM models are constructible. ‘Design models’ and ‘constructible models’ differ on the accuracy, development and details present in the model. While all BIM models can be used to communicate a building concept, they require data to support construction, fabrication and procurement to be ‘constructible’3D models—something the industry really needs today.
A constructible model allows designers, engineers and contractors to streamline their processes and improve efficiency and productivity throughout the project lifecycle. Architects use constructible BIM to create a centralised digital (virtual) representation of important information related to a building; MEP contractors use it to reduce model creation and data capture overheads; contractors use it to estimate, plan and manage construction; and building owners can use the same BIM model for the operations and maintenance of structures throughout their lifecycle.
Thus, Constructible BIM allows all stakeholders to work efficiently, collaboratively and synergistically towards constructing and operating a modern building. It also helps reduce construction costs, increase construction speed and efficiency, minimise construction waste and increase sustainability over a building’s lifetime.
Constructible BIM education and adoption
While the projects being delivered by Trimble customers are exemplary, the wide-scale adoption of Constructible BIM is also being facilitated through proper training and guidance to ensure its proper implementation in the construction process.
Constructible BIM is actively being added into the curriculum across colleges and universities to train engineers to be future-ready. In Europe, some academic institutions are even working to create a common framework for BIM education to ensure all students have the proper skills required for the next generation of construction. Programs like Tekla Campus encourage this transition by granting students free access to Constructible BIM software, like Tekla Structures, and providing support and instructions through online tutorials and on-site training sessions.
In India, Trimble has launched the Tekla Authorized Training Centre (ATC) programme across the country to build a pool of skilled and talented engineers and construction professionals that can contribute to the ongoing transformation of the Indian construction industry. Trimble has so far trained and certified over 700 professionals through its ATCs, and aims to grow this number to 10,000 professionals by 2020.
Even though there are many factors driving the surge in Constructible BIM, its adoption in India is still not happening at a desirable pace. Early adopters like Larsen & Toubro (L&T) have embraced Constructible BIM in true letter and spirit. The adoption of the latest technologies by any company is directly related to the management’s vision, desire to improve internal processes and become more competitive, and it’s a matter of pride that nearly every progressive company in the construction industry and its ecosystem today has adopted Trimble’s Constructible BIM—and the number keeps growing with every passing day.
