Automation in Construction in brief – 26/04/2025
Automation and Digitization
The authors reviewed AI’s impact on sustainable construction management from 2014 to 2024, highlighting its role in automation, sustainability, and efficiency. They found AI effective in real-time monitoring, carbon reduction, and project management automation, including quality control and cost prediction. While challenges in integration remain, the study emphasizes AI’s potential in advancing construction robotics, 4D printing, and green building systems, driving more sustainable construction practices.

Google’s AI-powered search features, notably AI Overviews—which generate short, AI-written summaries at the top of search results—now serve over 1.5 billion users monthly across more than 100 countries. The company has introduced ads within these summaries and is testing an “AI Mode” for complex queries. Despite regulatory scrutiny, these innovations are boosting user engagement and monetization.

OpenAI has introduced a “lightweight” version of its ChatGPT Deep Research tool, powered by the o4-mini model, to reduce operational costs while maintaining high-quality responses. This version delivers shorter outputs but retains the depth and quality of the original. Free users can perform up to five tasks monthly, while paid tiers receive higher limits.The tool activates by default when usage limits are reached on the original model.
Perplexity AI plans to launch its own browser, Comet, in May, designed to track users’ online activity—including purchases, browsing habits, and travel—to deliver hyper-personalized ads. CEO Aravind Srinivas argues that such data is essential for building richer user profiles beyond work-related queries. The company has secured a partnership with Motorola to pre-install its app on Razr phones and is reportedly in talks with Samsung.
Design changes in EPC projects for pumped storage hydropower systems are hampered by semantic heterogeneity, complicating Building Information Modeling (BIM) workflows. To address this, the authors propose an ontology-based semantic framework to unify decentralized BIM knowledge, enhancing data standardization and collaboration. A prototype system, validated through a case study, automates design change management, improving system efficiency and supporting carbon neutrality goals in renewable energy construction.
Construction Robotics
A self-adaptive seam detection framework for robotic welding in unstructured environments has been developed. By leveraging an enhanced pose estimation algorithm based on a single RGB image, the system autonomously determines the workpiece’s position, optimizing robot movements for precise seam extraction. This method, combining passive and active vision, eliminates human intervention and improves efficiency by 72% compared to traditional techniques. The framework offers a cost-effective, automated solution for dynamic industrial settings.

Engineers have enhanced RoboBee’s landing capabilities by drawing inspiration from the crane fly’s unique appendages.The new design enables the micro-robot to land on uneven surfaces with improved stability, mimicking the fly’s ability to grasp and stabilize itself mid-air. This advancement marks a significant step in bio-inspired robotics, potentially aiding in search-and-rescue operations and environmental monitoring.

Space Construction
The global space economy soared to $399 billion in 2024, driven by private sector growth and a record number of satellite launches. Around 13,000 satellites now orbit Earth. Existing international treaties, like the Outer Space Treaty of 1967, offer limited governance. Experts warn that stronger regulations are needed to manage congestion, prevent monopolies, and ensure the sustainable, equitable use of space.

NASA’s Curiosity rover has uncovered evidence suggesting that Mars once had a dynamic carbon cycle. Analysis of carbonate minerals in Gale Crater indicates that carbon dioxide was sequestered into rocks, possibly through mineral weathering processes. This finding challenges previous models that proposed a continuous carbon cycle on early Mars, implying instead that the planet’s carbon was largely removed from the atmosphere and locked away in the crust. The discovery provides new insights into Mars’ climatic history and its potential to support life.

NASA is exploring the possibility of constructing large-scale radio telescopes on the Moon’s far side to study the universe’s “cosmic dark ages”—a period between 80 million and 420 million years after the Big Bang. This epoch remains largely uncharted due to interference from Earth’s ionosphere. Proposed projects like the Lunar Crater Radio Telescope aim to detect faint 21-centimeter hydrogen signals, potentially shedding light on the formation of the first stars and black holes. Challenges include lunar construction logistics and extreme environmental conditions.
NASA’s Lunar Gateway, a cornerstone of the Artemis program, has completed its initial assembly. Despite this, the project faces mounting criticism and political scrutiny. Some experts argue that the Gateway’s utility is limited, suggesting that direct lunar missions could be more efficient. Additionally, with the Trump administration’s focus shifting towards Mars exploration, the Gateway’s future remains uncertain. The program’s viability may hinge on upcoming budget decisions and political support.
