Now, let’s look at each topic in detail.

1. Digital Design and Construction Management Using BIM/CIM

BIM (Building Information Modeling) and CIM (Construction Information Modeling) are methods of representing buildings and infrastructure as three-dimensional digital models and centrally managing information from design and construction through maintenance. Because stakeholders can collaborate on a 3D model instead of drawings, interference checks at the design stage and simulation of construction procedures become easier, reducing rework and improving quality. In Japan, the Ministry of Land, Infrastructure, Transport and Tourism is promoting the use of BIM/CIM in public works, and adoption is progressing mainly in large-scale projects.

Current challenges for BIM/CIM include a shortage of software and skilled personnel and ensuring data interoperability between companies and systems. Nonetheless, the benefits are substantial—such as automating quantity estimation from BIM data and using it for post-completion maintenance—so further spread to small- and medium-sized sites is expected. In the future, BIM/CIM will likely become more advanced, evolving into real-time construction management and infrastructure monitoring via digital twins linked with IoT sensors.

2. Advancement of Construction Management through AI

The use of AI (artificial intelligence) is expanding into construction management, which has relied on the experience and intuition of skilled technicians. Efforts are underway to use AI to automatically assess progress and quality, and to propose optimal schedules based on past project data. For example, systems that analyze site camera footage with AI to detect workers not wearing helmets and issue alerts, and technologies that automatically measure dimensions of as-built shapes from construction photos, are already in practical use. AI is also expected to support project management by predicting weather-related or schedule-delay risks so that countermeasures can be taken in advance.

The benefits of AI in construction management include reducing human error and improving operational efficiency. Challenges include accumulating sufficient data to train AI and raising site staff literacy to accept AI recommendations. Because each construction site has different conditions, it is necessary to secure the quality and quantity of data for AI training. Still, aggregating construction project data in the cloud and having AI guide optimal resource allocation and schedules in real time—i.e., smart construction management—may become mainstream.

3. Smart Construction and Automation of Construction Machinery

To address labor shortages and boost productivity, the smartification and automation of construction machinery and processes are accelerating. In ICT-based "smart construction," surveying data and 3D design data are loaded into construction equipment to assist operators or enable machines to perform earthwork automatically. For example, GPS-guided bulldozers and hydraulic excavators that support even inexperienced operators to perform high-precision grading are becoming more common. Remote operation and autonomous operation of machinery are also being introduced in disaster recovery sites and hazardous environments.

Robotics should not be overlooked. Initiatives are underway nationwide to automate heavy or dangerous tasks with robots—such as automatic rebar tying and concrete placing robots, and unmanned construction systems for tunnel excavation. The challenges for smart construction and automation include site-specific customization and large initial investments, but government-led initiatives like i-Construction are providing tailwinds, and adoption is expected to grow. In the future, a "digital site" where multiple machines and robots coordinate in real time to perform optimal construction is within view.

4. Evolution of Drones and Surveying Technologies

The use of drones (unmanned aerial vehicles) and the latest surveying technologies is becoming standardized to perform high-precision surveying and inspections efficiently. Even on vast sites that previously required significant time and manpower for surveying, aerial photos taken by drones can be analyzed to produce 3D terrain models and perform earthwork volume calculations in a short time. Drones equipped with laser scanners (LIDAR) can obtain accurate terrain data even in areas covered by trees. Drones are also active in bridge and dam inspections, greatly reducing the risk and effort of inspections at heights or in narrow spaces.

In surveying, RTK-GNSS is becoming widespread, enabling centimeter-level high-precision positioning; it is becoming an era in which high-precision surveying can be performed with smartphones or dedicated receivers without the need for veteran surveyors. This enables rapid control of as-built shapes and quantity evaluations on site, improving the efficiency and accuracy of construction management. However, drone use raises issues such as compliance with aviation laws, operator skill acquisition, and surveying data processing. Going forward, automatic cloud-based analysis and combinations with AI-based anomaly detection will further advance drone and surveying technologies.

5. Utilization of Remote On-site Technologies

"Remote on-site" technologies that allow confirmation and witnessing of construction status remotely are attracting attention. This involves using wearable cameras or smartphones for live footage so that offices or other remote locations can virtually inspect and supervise the site. The Ministry of Land, Infrastructure, Transport and Tourism is actively promoting remote on-site methods, and attempts to conduct online construction inspections have increased. Multiple experts can simultaneously view footage remotely and discuss, making on-site inspections—previously difficult to schedule—easier to carry out.

The benefits of remote on-site include improved efficiency by reducing travel time and enabling distant veteran technicians to share expertise immediately. Challenges include ensuring a stable communication environment and the limitations of understanding site conditions from images alone. With the use of 5G networks and high-performance cameras, these challenges are being addressed, and remote on-site is expected to be a key measure for work-style reform and productivity improvement. In the future, combining MR (mixed reality) technologies could enable a "virtual site supervisor" who can give instructions and perform inspections remotely as if present on site.

6. Promotion of Safety DX (Digital Safety Management)

DX is also making inroads into construction site safety management. To reduce workplace accidents, companies are advancing the digital enhancement of safety management. Specifically, wearable devices with sensors are being distributed to site workers to detect accident risks such as falls and send alerts to managers. There are also proximity alert systems that automatically stop machinery when it detects a worker approaching, and initiatives where AI cameras detect dangerous behaviors on site (e.g., unsecured work at height).

Safety DX is bringing about a paradigm shift from "be careful because it's dangerous" to "manage so it doesn’t become dangerous." The aim is to replace paper checklists and experience-based safety management with data- and technology-supported systems to establish a preventive safety culture. Examples include systems that digitally collect and analyze near-miss information to visualize warning signs and VR training that uses virtual danger experiences. Looking ahead, initiatives aiming for zero accidents through real-time monitoring using IoT and AI are expected to expand, and there may be moves toward legal mandates for safety devices.

7. Efforts Toward Carbon Neutrality

Environmental considerations are also an important trend in the construction industry. As Japan has declared carbon neutrality by 2050, decarbonization efforts are required on construction sites. Specifically, construction equipment is being shifted from diesel to electric or hybrid machines, and renewable energy is being used in site offices. New low-carbon cements and the use of recycled aggregates are being promoted to reduce CO2 emissions in concrete production. The increased use of wooden construction and locally sourced timber is gaining attention for its long-term carbon sequestration effects.

Furthermore, more companies are visualizing CO2 emissions across entire construction projects and setting reduction targets. Companies recognize that reducing environmental impact is directly linked to corporate value and are implementing measures such as energy-saving construction and waste recycling. For example, some general contractors install solar panels at construction sites to supply power and analyze machinery operation data to reduce idling time. Although many challenges remain in achieving carbon neutrality, stronger environmental regulations and green investment trends will likely make sustainable construction methods standard.

8. Work-Style Reform in the Construction Industry

Work-style reform—balancing improvement of harsh working conditions with productivity gains—is a major theme. Long working hours had been the norm in construction, but legal revisions have led to the full application of overtime limits from fiscal 2024. To comply, onsite operations are adopting two-day weekends, reducing night work, and improving efficiency through ICT. For example, in construction management, tablet-based reporting and sharing let staff finish their day at the site without returning to the office, reducing unnecessary travel and handwritten tasks.

Work-style reform enhances employee health and retention and helps secure human resources. Jobs once seen as "unable to rest and tough" have gradually improved due to young technicians’ changing attitudes and DX promotion. However, if project schedules and budgets are tight, site burdens may not decrease—a remaining challenge. It is necessary to encourage understanding from clients for work-style reform and create environments that allow appropriate project timelines and contract adjustments. Ultimately, achieving a high-productivity, smart site operation that enables work to finish within regular hours with limited personnel is the goal.

9. New Strategies for Securing and Developing Human Resources

Amid a declining birthrate and aging population, the construction industry faces severe labor shortages. With fewer new entrants and an aging skilled workforce supporting sites, securing and developing human resources is an urgent issue. Companies are improving workplace attractiveness through higher wages and better working conditions and are creating environments where women and younger workers can thrive on site. To cultivate talent fit for the DX era, firms provide training in BIM, programming, and AI both internally and externally, aiming to develop new skilled workers who combine traditional craftsmanship with digital technology.

For skill transfer, efforts include compiling veterans’ know-how into videos and manuals for sharing and using AR glasses to enable real-time guidance from experts. Collaborating with high schools and vocational schools to promote the appeal of construction and attract the next generation of workers is also important. The government is introducing measures to support young entrants and improve treatment for skilled workers, and industry-wide systematization of talent development is expected to advance. Companies that succeed in securing and developing human resources will have a competitive edge in the future construction market.

10. Latest Developments in Regulations and Policies

Attention should also be paid to regulatory and policy trends that support transformation in the construction industry. The Ministry of Land, Infrastructure, Transport and Tourism is actively supporting digitalization and labor-saving industry-wide efforts with initiatives such as "i-Construction" and the "Construction DX Promotion Plan." Public works bidding now includes bonus points for BIM/CIM utilization and ICT construction, favoring companies that proactively adopt digital technologies. The revised Construction Business Act, phased in from 2024 to 2025, includes measures to promote work-style reform, mandate appropriate project schedules, and encourage electronic contracting. These legal changes aim to correct unreasonable schedule compression and low-price bidding and rationalize construction systems through ICT.

Other ongoing initiatives include the spread of the Construction Career Up System and efforts to standardize and open construction data. Local governments are increasingly creating their own DX and environmental support programs. Looking ahead, policy trends may include stricter carbon neutrality-related regulations (e.g., requiring decarbonization plans for projects above a certain scale) and expanded support for developing digital human resources. For industry players, keeping up with the latest policy information and incorporating it into corporate strategy is directly linked to strengthening competitiveness.

Conclusion: Focus on Next-Generation Tool "LRTK" That Supports DX

We have explained the 10 latest trends in the civil engineering and construction industry. While each trend is a distinct theme, they are interrelated and together drive industry-wide change. From the perspective of DX promotion and productivity improvement, attention is growing for new technologies such as LRTK (a smartphone positioning system that combines high-precision GNSS receivers). By using LRTK, anyone on site can achieve centimeter-level positioning accuracy without specialized surveying instruments. This not only speeds up as-built confirmation and land surveying but also allows positioning data to be shared in the cloud so that progress and quality can be monitored remotely.

Thus, LRTK—a simple surveying tool combining a smartphone and GNSS—can serve as a versatile solution contributing across multiple fields. Introducing it as part of on-site DX can help improve construction quality, streamline surveying, and enable remote support through real-time information sharing. The civil engineering and construction industry is at a time of significant change. By keeping up with the latest trends and actively adopting new technologies and tools, let’s work together to build a sustainable, highly productive future for construction.
