The pandemic has essentially thrown contractors into the contech deep end and proven the effectiveness of digital workflow management software, progress tracking in real time and advanced schedule optimization, all of which McKinsey anticipates will increase in usage and investments.
McKinsey found that designers and engineers rely on digital collaboration tools like BIM even more now. In addition, leading contractors are using 4D and 5D simulations to optimize scheduling of workers and shipments, while digital twins are being used increasingly early on projects and lasting through their commission.
Modular building is more than a speedy option for project delivery, McKinsey wrote. Controlled environments for construction cannot be created onsite, so modular building will likely continue to make more sense in a world of restricted movement and interaction. Off-site construction allows for fewer workers as well as lower construction risks, and it feeds into BIM well. For these reasons, McKinsey expects a gradual increase in off-site fabrication.
Since the pandemic began, technologies also have evolved. Software companies have introduced products — such as wearables and AI sensors — to detect when workers do not maintain social distancing practices or to limit a workspace to only a handful of workers. Other new practices, such as virtual site inspections, can enhance safety and shorten the time it takes to perform jobs.
Online communication and collaboration has been crucial during the pandemic, and as the efficiency of working from home has been proven, certain aspects may remain integrated in construction going forward, McKinsey and others say.
United Rentals, the equipment rental company, developed virtual reality simulators to train heavy equipment operators. Now, according to UR’s United Academy Director Bal Guerrero, the company has developed remote practical evaluations, and is in the process of validating them with industry associations. Instructors can view forklift operators through mounted cameras and remotely assess if they are prepped for the field. This will continue to be useful when contractors need certifications but instructors are not available for in-person evaluations, Guerrero said.
