AI in Construction: Transforming an Age-Old Industry

Despite initial apprehensions towards adopting new technologies, construction and architecture companies invested $50 billion in AEC tech between 2020 and 2022. After decades of slow progress, AI is finally making its way to construction sites, promising profound impacts on the industry.

A Deloitte report indicates that the integration of AI and advanced data analytics in construction projects can lead to cost reductions ranging from 10% to 15%. These technologies can streamline the design review process and help teams produce more accurate estimates, reducing budgets and timeline deviations by 10-20% and engineering hours by 10-30%. 

Consequently, the AI in construction market is expected to be worth $151.1 billion by 2032.

AI in construction: How does it work?

AI in construction utilises machine learning and advanced data analytics to improve efficiency, safety, and quality control across various project phases. Machine learning enables computers to learn from data without being explicitly programmed, allowing apps to identify patterns, make predictions, and automatically improve performance. In construction, machine learning is used to identify hazards, improve scheduling, and forecast maintenance issues.

Deep neural networks, a specific type of machine learning model inspired by the human brain, consist of layers of interconnected artificial neurons that analyse complex data and extract meaningful insights. These networks are used in construction to analyse images and videos from sites, helping to identify and fix disparities between the project and results, and to monitor worker productivity.

Practical aspects of AI in construction

There are several benefits to AI and automation in construction: 

• Improved safety: AI-powered tools monitor construction sites for potential safety hazards and alert workers to take preventive measures.
• Enhanced productivity: AI helps automate repetitive tasks and optimise resource use, boosting workforce productivity.
• Quality control: AI algorithms analyse data to identify errors or omissions in designs or construction processes.
• Predictive analytics: AI predicts project delays or cost overruns, allowing proactive intervention.
• Design optimisation: AI analyses design parameters and proposes improvements, enabling the construction of more robust and effective structures.

Risk management

Risk management is a systematic procedure that helps recognise, evaluate, and mitigate strategic, financial, legal, and security threats. In construction, it helps avoid costly delays and rework and keeps the environment safe for personnel. Autodesk's Construction IQ is an example of an AI-driven risk management tool, identifying and helping to prevent design, RFI, quality, and safety risk factors.

Project monitoring and control

Remote project monitoring and anomaly detection significantly improve project management. EarthCam is an innovative AI-driven software that allows project managers to monitor progress remotely and detect anomalies, such as ladders at significant heights, through object detection and an AI-driven media dashboard.

AI in construction project management

AI-powered solutions in construction management offer:

• Efficient scheduling: AI considers task dependencies, priorities, and workforce availability to optimise schedules.
• Customised workflows: AI creates tailored workflows to meet specific project needs.
• Budget control: AI helps manage project budgets, reducing administrative workload and costly mistakes.
• Streamlined documentation: AI simplifies project documentation processes.

Safety and productivity tracking

Safety is paramount in construction. AI enhances safety measures and reduces accident risks by analysing real-time data from video surveillance and IoT sensors. viAct, for instance, uses AI algorithms to monitor construction sites for safety violations, alerting for unsafe acts, dangerous situations, and productivity monitoring.

Plan-build comparison

Plan-build comparison, traditionally time-consuming and error-prone, has become more efficient with AI. OpenSpace.AI captures construction site data and compares it to construction plans, identifying discrepancies and enabling prompt issue resolution.

Construction documentation

Accurate site documentation is crucial for transparency and accountability. StructionSite, an AI-powered platform, uses computer vision and machine learning to automate photo documentation, track progress, and facilitate virtual walkthroughs, improving collaboration and reducing manual documentation time.

Design optimisation

AI allows for the analysis of vast amounts of data and the generation of multiple design options through generative design, which considers cost, material efficiency, and structural integrity. Tools like Autodesk's Fusion 360 automate the design process.

Building information modelling (BIM)

BIM integrates design data with construction information. AI-powered BIM platforms provide real-time access to project data, enhancing collaboration and decision-making.

Internet of Things (IoT)

IoT technologies collect real-time data from sensors embedded in buildings and construction sites. AI algorithms analyse this data to track equipment, forecast maintenance needs, and monitor structural health.

Sustainable construction practices

AI contributes to sustainable construction by optimising energy consumption, material selection, and recycling processes. AI sensors can analyse energy use patterns and optimise systems to reduce consumption.
