On occasion, our engineers are asked "Why should we have a registered engineer (PE) involved in a mechanical design?" It's a valid question. In some applications, PE involvement is required by law, especially in areas of public safety. However, there are compelling reasons even in areas where PE involvement is not specifically codified.
For example, OSHA recognizes that ASME compliant lifting devices are a part of a safe work place. The ASME standard states that the device must be designed by a qualified person. If you are the buyer of equipment, how can you be sure your device was designed by a "qualified person"? If you are the seller, how can you prove your design was designed appropriately and in accordance with the standards? At a minimum, KTM Solutions recommends the following:
(1) Be sure that the device is in compliance with ASME B30.20 and ASME BTH-1 and includes an ASME tag, and
(2) Insist the seller provide documentation that demonstrates the design was accomplished by a qualified person. A PE sealed drawing is a credible way to prove qualification.
KTM Solutions designs and delivers professionally engineered mechanical systems including fixtures, mezzanines/platforms, box girder beams, and BTH devices. Our products are designed specific to each application, in compliance with ASME standards. We offer CE markings for devices delivered to the European Union. All services include PE sealed engineering documentation for your customer's compliance records.
What about other mechanical systems? PE oversight of mechanical design is never a bad idea.
