I recently contributed to HKA's CRUX 2021 report, Operating in Uncertain Times, which presents an analysis of causes of construction disputes globally (find it here). One of the issues I was involved in discussions on, and subsequently talked about at the launch in conjunction with RICS, was the potential of technology to reduce disputes. 

I sounded a warning that technology could both reduce disputes and increase them: to a certain extent the skills of the people using the technology is absolutely critical - I say that with particular reference to BIM. I also mentioned drones and AR use on sites as these are potentially valuable in saving time, money and identifying flaws perhaps even we couldn't see. During COVID-19 times, when site access might be restricted or the workforce reduced, these could be additionally valuable tools. 

Here is one such product, launching currently (I've not tried any of these products, but the article caught my eye). The level of accuracy seems to be key: imagine identifying out of tolerance elements on site before the mm-tight piece of MEP equipment arrives on site, only to find it doesn't fit... I also see huge benefits for both projects and training in being able to stream live feed to multiple team members, allowing reactive problem solving.

Is this technology a replacement for the Resident Engineer? I doubt it (not yet, anyway, but let's see how AI gets on). However, I do see huge potential benefits although we don't know currently know how much it costs!
