Shocked! The tower equipment couldn’t be installed – and it was because of this. The man was silent while the woman cried; it was truly heart-wrenching~

One day, while I was at the construction site’s project office, the construction team leader came over and said that the bolt seats of one of the tower equipment units were located at the midpoint, whereas the civil engineering structure had them positioned in the center. I rushed over to take a look; the crane was holding up a tower over 30 meters tall, and the difference between its base and the bolts was 11.25°, making it impossible to install it. How on earth did this happen? 1. When preparing engineering drawings, the equipment team recommends a uniform distribution across the span to both the civil engineering team and the manufacturing units. 2. The designers at the manufacturing unit were beginners; they changed the layout in version 0 to a centered and evenly distributed arrangement, and then sent the drawing to the engineering company for review. 3. During the review, the advice provided by the mechanical engineering team was to arrange the foundation bolts evenly across the span. The civil engineering team was also inexperienced and modified their own drawings according to the version 0 design. 4. When Version 1 of the layout was sent, the equipment team saw that the drawings had been modified and therefore did not pay attention to this matter. The civil engineering department failed to examine the manufacturer’s drawings carefully and did not notice that Version 1 of the drawing had already been modified. 5. When preparing drawings for the civil engineering discipline, they are sent to the mechanical engineering discipline for review; however, the mechanical engineering team does not examine the drawings carefully and fails to notice that the civil engineering drawings are centered. 6. As a result, the equipment is positioned in the middle of the span, while the civil engineering work was carried out with it placed in the center, which makes assembly impossible. Since it has already happened, it must be resolved quickly. The advice from the equipment specialists is to cut from the lowest point of the skirt, rotate it by 11.5°, and then weld it back in place; this will allow for a smooth installation. The question is: should it be cut while hanging, or should it be put back in place first before cutting? The construction workers believe that installing this equipment is very difficult, as it’s tricky to pass through various layers of structure; moreover, the lifting capacity of the crane is sufficient, making it an easier approach to carry out the cutting and welding tasks. The owner strongly disagreed with this, stating that it was too dangerous; who would be responsible in the event of an accident during construction? Swinging while something is suspended poses a risk to construction safety as well as to the quality of welding. Ultimately, this device was lifted out through the various floor layers, laid flat, cut, polished, rewelded, and reinstalled in place. What a huge impact a small oversight by the designer can have on the site! (This article is reproduced from the Internet; thanks to the original author)
