The Construction industry faces significant challenges in maintaining productivity and managing workforce shortages. Dr Ehsan Noroozinejad from the Urban Transformations Research Centre, Western Sydney University, Australia, provides an international view on how technology can help.
Despite its critical role in driving economic growth, the construction sector has historically lagged in productivity improvements compared to other industries. This discrepancy is partly due to the industry’s inherent complexity, reliance on manual labour, and the bespoke nature of many construction projects. Moreover, skilled labour shortages have become increasingly acute, exacerbating project delays, increasing costs, and affecting overall project quality. In response to these enduring challenges, Offsite Construction has emerged as a transformative approach.
Recent industry reports suggest that Offsite construction is on the rise, with the modular construction market alone projected to grow at a compound annual growth rate (CAGR) of 6.5% from 2020 to 2025. This growth is indicative of the sector’s potential to significantly impact overall construction industry efficiency. Furthermore, a survey conducted by the National Institute of Building Sciences in the United States highlighted that over 70% of contractors who have adopted offsite construction methods reported improvements in project schedules, with 65% noting reduced project budgets and 55% experiencing decreased construction waste.
Despite the promising adoption rates and benefits, there remains a significant knowledge gap regarding the integration and future role of smart and emerging technologies within this sector. While previous studies have laid a foundational understanding of offsite construction’s advantages, less attention has been given to how immersive technologies such as artificial intelligence (AI), robotics, and the Internet of Things (IoT) can further enhance these benefits.
All these emerging technologies have a future potential impact on offsite construction and can redefine the landscape of the construction industry. By exploring the integration of smart technologies in offsite construction processes, these strategic advancements not only address current industry challenges but also pave the way for a more efficient, sustainable, and innovative construction sector.
Drones and remote monitoring
Drones have rapidly become indispensable in offsite construction, offering aerial photography, surveying, and remote monitoring capabilities. They enhance site security, track progress, and can inspect hard-to-reach areas, ensuring project milestones are met efficiently and safely. As drone technology advances, its integration into offsite construction is expected to deepen, with potential applications in logistics management and real-time adjustment of project plans.
Smart sensors
Embedded within construction materials or placed around the worksite, smart sensors provide critical data on environmental conditions, structural integrity, and material quality. This real-time data collection facilitates predictive maintenance, improves safety, and ensures compliance with specifications, significantly reducing the risk of errors and rework.
Artificial intelligence and machine vision
AI and machine vision systems are set to transform offsite construction by automating design, enhancing precision in manufacturing components, and optimising logistics. By analysing vast datasets, AI can predict project outcomes, optimize resource allocation, and even guide robotic systems in assembling complex structures, ensuring adherence to design specifications with minimal waste.
Extended reality (virtualization)
Extended reality (XR), encompassing augmented reality (AR), virtual reality (VR), and mixed reality (MR), offers immersive design and planning tools that bridge the gap between digital models and physical construction. XR technologies allow engineers and clients to visualize and interact with building designs before construction begins, facilitating better decision-making, enhancing collaboration, and reducing the likelihood of costly changes.
Integrated project management systems
Digital platforms that integrate project management tools with real-time data from the construction site are becoming a cornerstone of efficient offsite construction. These systems streamline communication, document management, and project tracking, ensuring that all stakeholders have access to up-to-date information, which is crucial for the timely delivery of projects.
Wireless technology
The advent of 5G, 6G and future generations of wireless networks promises to significantly enhance connectivity between offsite manufacturing facilities and construction sites. Enhanced bandwidth and lower latency enable the seamless transfer of large datasets, support remote operations, and facilitate the use of IoT devices, improving coordination and efficiency across projects.
Big data and analytics
The construction industry generates vast amounts of data, and through big data analytics, this information can be leveraged to make informed decisions, optimise workflows, and predict trends. In offsite construction, analytics can improve supply chain management, forecast project risks, and enhance quality control processes, leading to more reliable and predictable project outcomes.
Robotics
Robotics in offsite construction heralds a shift towards more automated and precision-driven processes. From welding and cutting to assembling parts and applying finishes, robotic systems offer unmatched speed and accuracy, reducing manual labor requirements and enhancing safety on the production floor.
Internet of Things (IoT)
IoT technology integrates sensors, software, and other technologies to connect and exchange data with devices and systems over the internet. In offsite construction, IoT devices can monitor the condition of materials during transport, track inventory, and ensure components are assembled correctly, paving the way for more dynamic and responsive construction ecosystems.
3D Printing and additive manufacturing
3D printing and its advanced iterations (such as 4D printing, where objects can change shape over time) are set to revolutionise how components are produced for offsite construction. Offering the ability to create complex, customized parts with reduced material waste, additive manufacturing supports sustainable construction practices and opens up new design possibilities that were previously unachievable.
Industry implications and future outlook
The exploration of these key technologies illuminates a path towards a radically transformed offsite construction landscape. This technological revolution is setting the stage for an industry evolution, characterised by unprecedented levels of efficiency, safety, and environmental sustainability. As we delve into the practical applications and potential of these innovations, it becomes evident that their integration is not just enhancing offsite construction processes but is pivotal in addressing long-standing industry challenges.
This progression towards a technology-centric construction model heralds a new era of construction practices. It promises a shift from traditional, often inefficient methods to a future where projects are executed with greater precision, agility, and sustainability. The implications of this shift are profound, extending beyond the immediate benefits of cost and time savings to fundamentally reshaping how projects are conceived, designed, and delivered. It signals a move towards a construction ecosystem that is more resilient, adaptable, and responsive to the needs of society and the environment. For practitioners in the construction industry, the message is clear: the future is now. The integration of these advanced technologies into offsite construction is not merely an option but a necessity for staying relevant and competitive in a rapidly evolving industry landscape.
The collective expertise and vision of engineers and industry practitioners will be instrumental in harnessing these technologies, steering the construction industry towards a brighter, more sustainable horizon. The journey towards an innovative and efficient future for the construction sector is well underway, guided by the light of emerging technologies. Let us all, especially engineers, lead the charge in adopting these advancements, shaping a future where construction is synonymous with efficiency, precision, and environmental stewardship.
