McKinsey puts a number on AI in construction: 39% of nonphysical work is automatable
Construction Dive reported on 22 July 2026 on a McKinsey study that mapped 150 workflows across 25 architecture, engineering and construction domains and estimated AI could automate 39% of nonphysical construction work, against 50% in architecture and engineering. It phases the opportunity: bid analysis, estimating and proposal drafting within 18 months; proprietary-data work such as requests for information, drawings and specifications over 18 months to four years; autonomous equipment and jobsite coordination beyond four years. Its build-versus-buy rule is blunt — build where your expertise is the product, buy where outside sources invest more than you could — with a warning that firms in the sector have historically struggled to scale software products.
Why it matters: A rare sector-specific automation estimate with a phasing timeline — useful whether you are deciding what to pilot first or what not to build in-house at all.
