Working in design and construction company can really cause a person to fluctuate the blood pressure wildly for so many reasons. One of it is the due to assembly of a component then reassembling it manually. In a factory a component are manufactured by robot, but when it was delivered in site and was repaired then it is when trouble comes, since some of components are microscopic it cannot be reassemble accurately. We have an ongoing discussion ATM to mitigate the problem. Have a good day Noisers, mine is a challenging day today.
