Path to BIM

BIM vs. drawings

BIM vs. drawings

Building Information Modelling, or Building Information Model efficiently describes the process of designing, building and operating a building collaboratively using one system of computer models rather than separate sets of drawings. You can experience the relevant building data rather than interpret it from drawings as lines, numbers and symbols. Different disciplines of the construction industry use different systems to create (author) models but you can combine them all in dfferent systems, such as Tekla BIMsight, using open BIM. You can check here how it is done in practice: Creating Tekla BIMsight compatible models.

How much does BIM save?

The graph shows the benefits of collaborative BIM versus using 2D or lonely BIM.

BIM benefits

As you can see, there is a dramatic business improvement moving from 2D projects to collaborative BIM.

The mechanical contractor J. C. Cannistraro, LLC analyzed cost data from 408 projects projects performed over 6 years. Their total value was $558,858,574. The percentage of change orders in relation to all costs drops significantly when BIM use increases.

Design Coordination Guide

We want to make your path to BIM as easy as possible. That is why we have created the Design Coordination Guide. It gives suggestions on how to use Tekla BIMsight in a construction project for design coordination.

The coordination process is critical to the success of the project. Careful early coordination will between trades will ensure that there are fewer errors arising on the construction site.

Design coordination guide

Read through the eight steps of the guide, and you'll be on your way to successful BIM projects. You can use our guide as a basis for your company's own guideline.

In BIM collaboration, we utilized the models in weekly all-discipline coordination meetings. With all of the discipline models loaded into Tekla BIMsight, we were able to see conflicts and possible design changes.
