No day is the same

A steel draftsman in heart and soul, Jan-Willem did not initially believe he would find engineering square silos such a challenge. He shakes his head as he reflects: “In my previous job at Oostingh Staalbouw I worked on stadiums, power plants and non-residential buildings, so how hard could square silos actually be… Well, I judged this rather wrongly.”

“The work here appeared to be less complex than my previous job. I judged this rather wrongly…”

Involved from A to Z

To provide an image of his dynamic work activities, he outlines a normal workday at his workplace in Aalten: “No day is the same, we are faced with everything you can imagine. Every day I start work by checking my mail. Then it is constantly something else. I draw a lot, I organise transports, I carry out the work preparation, request quotations, purchase things. We practically do anything imaginable, because we are involved in our projects from A to Z. Visits to the construction sites are also part of this. To Switzerland, South Africa or, for example, close by in Belgium. Primarily during the implementation, we check how it is progressing, to see if we have to make any adjustments. And of course, we are present at the best moment ever: the completion.”

Drawing with Tekla

Just like his colleagues, he draws with Tekla Structures, supported by CAD. Lifelike 3D models of the silo and its components are made on the basis of the calculations from the Structural Engineers. These models combine all information that is essential for the production of the components and the subsequent construction work. The geometry and dimension lines, the profiles and cross sections, the connection types and naturally also the materials. Jan-Willem: “Here it is important to bear profile deviations in mind. There is often a minimum difference between the theoretical and realistic dimensions. With the modelling and drawing it is important to consider these tolerances, that a project does not instantly get stuck if a panel is a fraction of a millimetre larger. This foresight, keeping the work of the assembly teams in mind, is important with the drawing work.”

Quality control

Another task that Jan-Willem has taken upon himself is the quality control of suppliers: “I visit the factories of our preferred providers on a regular basis to check what is produced on the basis of our drawings. Our suppliers are an important factor in our final quality, so we take that seriously. We are also, depending on the complexity, often present during construction. For example, to further explain issues such as a deviating construction order or the integration of a machine house.”

“Our suppliers are an important factor in our final quality, so we take that seriously.”

This involvement is what distinguishes TSC, states Jan-Willem: “One of my first projects was in Durban, South Africa. We organised the entire engineering from the office with a reliable supervisor of an excellent assembly team. I wanted to be present at the completion. In the end, I was only there to shake the hand of the client and receive their signature because there were points upon completion. It was a formality which took 30 minutes, but it does show that we take the project and the client seriously. And naturally I personally think it is amazing to see the result of our work with my own eyes, because that is why we do it.”
