Despite technological advancements, the construction industry remains largely unchanged from its practices a century ago, observes Sam O’Gorman, an associate partner at McKinsey. While the potential for enhanced productivity and profitability exists, the industry has been slow to embrace digital transformation compared to other sectors.
McKinsey’s research in 2017 suggested that productivity in construction could increase significantly with the adoption of new technologies. However, progress has been incremental rather than revolutionary. Mr. O’Gorman attributes this sluggishness to the industry’s resistance to widespread digital integration.
Various technologies have been touted as game-changers for construction, including 3D printing and modular construction. The University of Maine’s ambitious 3D printing project, for instance, showcased the construction of a sizable house using innovative materials. Despite such endeavors, practical challenges persist. 3D-printed homes remain costly to produce, with thick walls and limited applicability beyond flat, open sites.
Modular construction offers promise by prefabricating building components in factories and assembling them on-site. Dr. Habib Dagher of the University of Maine emphasizes its potential for superior quality control and efficiency. However, Neil Jefferson of the UK Home Builders Federation highlights regulatory hurdles and inflexible planning policies as barriers to widespread adoption.
Flexibility is crucial for developers, particularly in responding to market dynamics and altering plans as needed. While projects for public entities may navigate these challenges more smoothly, private developers face uncertainties regarding timely sales and project adjustments.
In conclusion, while technology holds promise for revolutionizing construction, industry-wide transformation requires overcoming regulatory obstacles and fostering adaptability. The path to modernization necessitates collaboration among stakeholders to realize the full potential of technological innovations in construction.
