Imagine stepping through a time portal and landing smack dab in the middle of a modern construction site. A hardhat might be your only giveaway that you’re not in a 1920s scene. According to industry expert Sam O’Gorman, the construction industry has a surprising lack of innovation, with processes remaining largely manual.
This stagnation is a missed opportunity. McKinsey Global Institute estimates the industry could be 50-60% more productive, generating an additional $1.6 trillion annually. While software and apps have nudged efficiency upwards, a digital revolution hasn’t materialised.
One futuristic solution grabbing headlines is 3D printing. The University of Maine’s BioHome3D, a 3D-printed house made with wood fibres and resin, showcases the potential. However, the technology faces hurdles. These homes are expensive, thick-walled, and limited to flat, open sites. While other 3D-printed projects exist, they remain a novelty.
Another contender is modular construction, where prefabricated building sections are assembled on-site. Proponents like Dr. Habib Dagher praise its efficiency and quality control. However, Neil Jefferson of the UK Home Builders Federation highlights a key challenge: inflexibility. Rigid plans clash with the unpredictable nature of development projects, especially those in private hands.
A UK company, Automated Architecture (AUAR), is trying to bridge this gap. Their micro-factories create timber houses using robots, offering a blend of customisation and prefabrication. This approach could potentially reduce labour costs and construction times.
While the spotlight often falls on the physical construction process, a quieter digital revolution is happening behind the scenes. O’Gorman highlights the use of AI for land identification, future value prediction, and design. These advancements are streamlining pre-construction activities.
Karoliina Torttila of Trimble, an industrial technology firm, believes these “invisible” improvements hold the key. Tasks like quantity surveying and health and safety procedures are now handled digitally. However, fragmentation remains a major obstacle. Construction projects involve numerous subcontractors, each with their own plans and processes. Disconnects between these teams can lead to costly mistakes later on.
Technology can bridge this communication gap. Creating a shared 3D model of the entire building allows for early detection and correction of discrepancies before they snowball into bigger issues. This fosters smoother collaboration despite the industry’s fragmented structure.
The future of construction isn’t necessarily about robots laying bricks. It’s about embracing a holistic digital transformation, from design and planning to communication and collaboration. By embracing these invisible changes, the industry can finally step out of the past and into a more efficient, productive future.
