Engineers need to be ready to embrace change when it comes to adopting new technology, according to Keith Bentley who has just retired from the post of chief technology officer at Bentley Systems, the firm he founded with his brother Barry almost 40 years ago in 1984. Speaking to NCE editor Claire Smith on the latest episode of The Engineers Collective podcast, Keith reflects back on how far the industry has come in terms of technological change in the last 40 years. He also talks about the challenges the sector has faced in taking on new practices but says he has enjoyed seeing projects thrive when they have used new approaches to project design and delivery. As he prepares to hand over his role at Bentley to Julien Moutte, Keith gives some advice to firms about how to drive technological change and gives a word of caution for businesses who have not yet fully moved to digital delivery and are not yet eying up the potential digital twins have to offer in delivering more improvements.
