Digital value engineering using BIM model

We bring the experience of device comparison sites to the project by helping you to implement the planned features at the lowest cost.

What is value engineering?

With value engineering, we find the materials and methods to achieve the required functionality, performance, and sustainability at the lowest cost.

In other words: for example, we design the building’s ventilation so that, taking into account the building’s structure, construction, flow characteristics, planned number of employees, occupancy, expandability, etc., no cooling, heating, ventilation, or shading equipment is under- or over-designed.

The necessary specialist engineering knowledge is supported by a software and hardware park to achieve the best value indicators, and the activity should be continued throughout the project.

How is value engineering based on a BIM model different?

At the heart of the BIM methodology is a BIM model with a large amount of information, which, with the workflow built on top of it, results in significant savings throughout the project.

This is because the parametric elements of the building model are interrelated, so if you change one parameter, the whole body changes – the elements adapt to the other elements, in the model, in the design sheet, and everything else, in a way that minimizes the manual work required.

Simply put: replacing one anemostat in a well-built BIM model with another, or moving it to a different point, automatically changes the technical characteristics of the whole air handling system (half or completely), and from then on it is just a push of a button for another simulation or an up-to-date cost calculation.

This makes variation analysis faster and more accurate, and the whole project more predictable and cheaper. There’s always something to grab in an investment, which is cumulatively true in an uncertain and unpredictable economic environment, with constantly rising labor and raw material prices, especially at the end of the era of cheap energy.

How does BIM model-based value engineering pay off?

The return and other economic indicators for projects can be achieved by increasing efficiency, which has two pillars:

• digitalization – BIM model, automation, Common Data Environment (CDE) and BIM services
• value engineering – aiming for optimal technical content at the lowest possible cost

If these two factors are present together, continuously throughout the project, it results in the following:

• wasteful design, construction or operational solutions can be avoided;
• avoid redesign problems due to loss of information;
• change management and the project will be fast and flexible;
• sufficient flexibility to keep costs under control;
• make all aspects of the project more predictable (timing, cost, processes, technical content, etc.)
• management has continuous access to transparent, real, and up-to-date information, without surprises.

Digital value engineering helps to maximize the benefits of the BIM methodology.
