Tekla Opened New Business Opportunities for thyssenkrupp Industrial Solutions in Vietnam

Armed with Tekla software, the engineers at thyssenkrupp Industrial Solutions in Vietnam now design cement plants for the world instead of just Vietnam.

Why Tekla?

In Vietnam, thyssenkrupp Industrial Solutions had focused on designing and making cement plants around the country and used traditional CAD/CAM software for civil and structural designs. However, in 2009 they received a request from the headquarters in Germany to produce 3D models for some structures to ease co-operation. As a result, the company began looking for 3D modeling solutions. This would turn it into a player in the global market.

After evaluation, thyssenkrupp Industrial Solutions Vietnam chose Tekla Structures because of its advantages over competing Building Information Modeling solutions, such as the ability to combine both concrete and steel structures in one model and its compatibility with PDMS, a 3D software solution for plant engineering.

The team in Vietnam purchased its first Tekla license and began training staff. They practiced by modeling buildings and structures of cement plants that the company had previously built. It was only after they became more familiar with the software that the company realized the potential of Tekla to be a game changer for them.

New business opportunities 

"At first, our intention was not to use Tekla to actually design a cement plant,” says Mr. Roland Chudalla, the Deputy General Manager of thyssenkrupp Industrial Solutions Vietnam. “However, as we got used to it, we found it a more efficient way of designing. It also opened new possibilities for us, enabling us to design and build complete, complicated buildings or structures for cement factories.

Armed with Tekla, the company can now take on new jobs that were previously too complex for them. This means that the company can find new business opportunities around the globe. 

Tabuk cement company order

Thyssenkrupp Industrial Solutions Vietnam had a good timing. In November 2011, the Tabuk Cement Company in Saudi Arabia ordered a complete cement grinding plant from their parent company. The order covered all equipment from the clinker feeding system to the cement bag packing plant and bulk loading facility.

The team in Vietnam was assigned to design six of the plant buildings including the main one, the gypsum crusher. The company decided to use Tekla’s BIM software for civil and structural engineering work. The plant is scheduled for completion in 2013.

"This was a challenging building to design because half of the building is underground,” Mr. Chudalla explains. “The part above ground is made of steel while the underground structure is made of concrete. Another complication was that the structure above ground would be used for housing heavy machinery. It was a very complex building to design.

Pit, rebar and concrete

The team included the excavation pit of the factory to the Tekla model because this allowed them to easily achieve the excavation quantity. As the terrain was quite simple, it could be easily modeled.

thyssenkrupp Industrial Solutions modeled the rebar with Tekla and utilized the information in the model: they issued the detailing drawings and bar bending schedule from the model, but as novice rebar modelers they needed some time for it. However, they already saw that benefits were quite clear.

The team was able to foresee and avoid difficulties in rebar installation, and spot clashes between rebar and rebar and cast-in items. They could check if the rebar arrangement was practical and reasonable. The contractor just cut the rebar following thyssenkrupp’s drawings and installed the rebar on site, without having to ask major questions from the team. “We felt that, with 3D modeling of the rebar in our office, we don’t leave any problem for the site people as we normally did in the past, when the conventional 2D design was applied,” says Mr. Nguyen Dinh Quan, Head of the Engineering Department of thyssenkrupp Industrial Solutions Vietnam.

Just five months

Even though the complicated Tabuk Cement plant was the first project thyssenkrupp Industrial Solutions Vietnam designed from scratch with Tekla, they succeeded in completing the work in just five months, thanks to the software. Using Tekla saved time for thyssenkrupp as they estimate that with traditional 2D method they would have needed 7-8 months.

According to Mr. Quan, Tekla excelled especially at three things: producing civil and structural steel design drawingsproducing correct bills of quantity and most importantly, minimizing the time and manpower needed for the design work.

"Tekla delivers quality and time and cost savings,” Mr. Quan says. “In the area of design, Tekla accelerated our work tremendously.”

Improving communication

Thanks to the Tekla’s multi-user function, the design team could work in parallel to build up the 3D model of the factory. Afterwards, the detailed drawings and bills of quantities were quickly generated directly from the model.

In addition, Tekla was good in handling changes, which is important in general as every thyssenkrupp Industrial Solutions project involves requests for modifications from customers. With Tekla Structures, the drawings and bills of quantities were updated accordingly as soon as the model was revised.

Another advantage was that models were easier to understand and thus made communication between project parties much easier.

Model-based communication made things very efficient,” Mr. Quan says. “Everybody from clients to different departments and contractors could see what we were talking about.

Fewer drawings

Using models meant that the team had to produce and distribute fewer drawings. This is significant because a complete cement factory could require up to 10,000 drawings and each drawing would have to be checked and approved before being sent to everyone in the team.

Better bids with quantity take-offs

Apart from using Tekla for structural design, the team in Vietnam has also found it useful for doing quantity take-offs. Now the company can prepare bids quickly and competitively.

According to Mr. Quan, Tekla allows the company to generate bills of quantity accurately, even on very complicated structures that traditional estimation methods struggle to handle. The software is also useful for controlling budget overruns from project modifications, and Tekla allows fast, easy review of architectural and structural concepts.

In Tabuk, the team used Tekla for material quantity takeoffs and sent the bills of quantities to the contractor on site who used it for ordering the concrete.

Tekla reduces the time and manpower required to do the quantity take-off and allows us to come up with bids quickly, accurately and competitively,” Mr. Quan says.

Polysius - possible only with Tekla

We could only have done this job with Tekla. If we had to use a regular CAD-CAM software, we would not have been able to design this within the required time frame and at similar quality at all.
