Modeling for Construction, Not Just for Drawings

Constructibility means ensuring in advance that a building or structure can be built efficiently, both in terms of time and money. Building Information Modeling, when developed accurately, helps the industry achieve efficiency with information-rich models and find possible problems before construction begins, reducing wasted materials. 3D models minimize costly surprises, RFI's (requests for information) and clears the way for more profitable projects.

With Tekla, constructibility is the foundation of developing BIM software. We produce our software to meet the needs of the industry, because we believe the more information a model includes, the more beneficial it is to all project parties.

Everyday Constructibility

Constructibility is a practical, everyday issue for builders. Because construction is a process, we want our software to support the whole workflow including the inevitable changes. As buildings comprise several materials, software should be able to handle the same.

Constructible 3D models allow the industry to make informed decisions early in the process. Tekla Structures is made for creating, combining and distributing highly-developed, accurate and information-rich structural models using any material. The builders can manage changes and avoid errors, find clashes and produce better quality with less waste.

Bigger, Better, Cheaper, Faster – Now

Current trends in construction promote constructability as architecture becomes increasingly complicated and designers and builders have to find ever more innovative solutions. The need to build successfully and safely is why accurate information is necessary even in the design phase.

Cost pressure is also ever-present. With constructible models, buildings can be constructed cheaper, better and faster. Processes can be easily planned and scheduled, and possible mishaps detected in the design phase before construction starts. This leads to less ad-hoc problem solving on-site.

The off-site building is another trend that’s gaining ground as the industry heads towards cost savings and a higher level of automation. Larger units, such as steel-roof assemblies and factory-built bathrooms, arrive prefabricated to the construction site to be installed when needed in the construction schedule. Naturally, these items need to fit exactly and stay on schedule, even when vast amounts of information changes on the project. This process definitely calls for accurate, as-built and up-to-date information, like the kind found in constructible models.

We have seen cases where the costs have been reduced by 50% by using BIM. Having constructibility issues sorted out before starting construction will inevitably lead to fewer errors.
