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

1. Digital design and construction management with BIM/CIM

BIM (Building Information Modeling) and CIM (Construction Information Modeling) are methods for 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, clash detection during the design phase and simulation of construction procedures become easier, leading to fewer reworks and improved 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-compatible tools and skilled personnel, and ensuring data interoperability with other companies and systems. Even so, the benefits are substantial—for example, automating quantity takeoff from BIM data and using it for post-completion maintenance—so wider adoption at small- and medium-sized sites is expected. In the future, BIM/CIM is likely to advance further and evolve into real-time construction management and infrastructure monitoring through digital twins linked with IoT sensors.

2. Advanced construction management using AI

AI (artificial intelligence) is increasingly being applied to construction management, which has traditionally relied on the experience and intuition of skilled technicians. Trials are underway to use AI to automatically judge construction progress and quality, and to propose optimal schedules based on past project data. For example, systems have been commercialized that analyze on-site camera footage with AI to detect workers not wearing helmets and issue alerts, or automatically measure as-built dimensions from construction photos. AI is also expected to support project management by predicting weather and schedule delay risks and prompting preemptive countermeasures.

The benefits of AI-based construction management include reducing human error and improving operational efficiency. Challenges include accumulating sufficient data for AI use and raising site staff literacy so they accept AI recommendations. Because construction conditions vary by site, it is necessary to secure the quality and quantity of data used to train AI. Nevertheless, a future where project data are aggregated in the cloud and AI guides optimal resource allocation and scheduling in real time—enabling smart construction management—may become mainstream.

3. Smart construction and automation of construction machinery

To address labor shortages and improve productivity, the smartification and automation of construction machinery and processes are accelerating. In "smart construction" using ICT (information and communication technology for civil engineering), surveying data and 3D design data are loaded into construction equipment to assist operator control or enable automated earthmoving by heavy machinery. For example, bulldozers and hydraulic excavators with GPS guidance systems that help even inexperienced operators achieve high-precision grading are becoming more widespread. Remote control and autonomous operation of machinery for unmanned operation are also being introduced in disaster recovery sites and hazardous work environments.

Robotics should not be overlooked. Initiatives are underway across the country to delegate heavy labor and dangerous tasks to robots, such as robots that automate rebar tying and concrete placement, and unmanned tunneling systems used in tunnel excavation. Challenges for smart construction and automation include site-specific customization and large initial investments, but the government's i-Construction policy provides tailwind support, so adoption is expected to expand further. In the future, realization of a "digital site" is conceivable, where multiple machines and robots coordinate in real time to execute optimal construction.

4. Advances in drones and surveying technologies

To conduct high-precision surveys and inspections efficiently, the use of drones (unmanned aerial vehicles) and the latest surveying technologies is becoming standardized. Even at expansive sites that traditionally required significant time and manpower for surveying, flying drones and analyzing aerial photos enables rapid creation of 3D terrain models and earthwork volume calculations. Drones equipped with laser scanners (LIDAR) can obtain accurate terrain data even under tree cover. Drones are also proving useful in bridge and dam inspections, greatly reducing the risk and effort associated with inspections at heights or in narrow spaces.

In surveying technology, centimeter-class high-precision positioning (cm level accuracy (half-inch accuracy)) using RTK-GNSS has become widespread, and we are approaching an era in which high-precision surveying can be performed with a smartphone or a dedicated receiver even without a veteran surveyor. This enables rapid as-built management and progress measurement on site, improving the efficiency and accuracy of construction management. However, drone utilization involves challenges such as compliance with aviation laws, pilot skill acquisition, and processing of survey data. Going forward, drone and surveying technologies will continue to evolve through cloud-based automatic analysis and integration with AI-based anomaly detection.

5. Utilization of remote site attendance (remote technologies)

"Remote site attendance," which allows verification and witnessing of construction status without physically visiting the site, is attracting attention. This involves mechanisms by which offices or remote locations can virtually inspect and supervise sites via live feeds from wearable cameras or smartphones. The Ministry of Land, Infrastructure, Transport and Tourism has been proactively promoting remote site attendance, and attempts to conduct online construction inspections have increased. Because multiple experts can simultaneously view and discuss video remotely, site inspections that were previously difficult to schedule can be conducted smoothly.

The advantages of remote site attendance include efficiency gained from reduced travel time and the ability for remote veteran technicians to immediately share expertise. Challenges include securing stable communications and the limitations of understanding site conditions from video alone. With the use of 5G networks and high-performance cameras, these issues are being resolved, and remote site attendance is expected to be a key measure for workstyle reform and productivity improvement. In the future, combining MR (mixed reality) technology could make it possible to give work instructions and perform inspections remotely as if one were physically present—making a "virtual site supervisor" a realistic prospect.

6. Promotion of safety DX (digital safety management)

The DX wave is also reaching safety management at construction sites. To reduce occupational accidents, companies are advancing the enhancement of safety management through digital technologies. Specifically, wearable devices with sensors are distributed to site workers to detect accident risks such as falls and send alerts to managers. There are also prox alert systems that automatically stop heavy machinery when they detect proximity to workers, and trials are starting in which AI cameras detect hazardous behavior in work areas (such as unsafe high-altitude work).

Safety DX is driving a paradigm shift from "be careful because it’s dangerous" to "manage so that it does not become dangerous." The aim is to replace paper checklists and experience-based safety management with data and technology to establish a proactive safety culture. Examples include systems that digitally collect and analyze near-miss (a close call) information to visualize danger signs, and the use of VR technology in training to simulate hazardous situations in virtual space. The future outlook for safety DX includes broader use of IoT and AI for real-time monitoring aimed at achieving zero accidents, and potential regulatory moves to mandate safety devices.

7. Efforts toward carbon neutrality

Consideration for the global environment is also an important trend in the construction industry. With Japan declaring carbon neutrality (net zero greenhouse gas emissions) by 2050, decarbonization efforts are required at construction sites as well. Specifically, there are moves to replace diesel construction machinery with electric or hybrid machines and to use renewable energy at site offices. To reduce CO2 emissions during concrete production, the use of new low-carbon cements and recycled aggregates is progressing. Additionally, the expansion of timber construction and the use of locally sourced materials are gaining attention because they lock carbon in place for long periods.

More companies are visualizing CO2 emissions for entire construction projects and setting reduction targets. Firms recognize that reducing environmental impact directly affects corporate value and are implementing various measures such as energy-efficient construction and waste recycling. For example, some general contractors install solar panels at construction sites to supply construction power, or analyze machinery operation data to reduce idling time. Although many challenges remain in achieving carbon neutrality, strengthened environmental regulations and the flow of green investment will likely make sustainable construction methods the standard going forward.

8. Workstyle reform in the construction industry

Workstyle reform, which aims to improve harsh working conditions while boosting productivity, is another major theme. Long working hours had become normalized in the construction industry, but legislative revisions have meant that overtime limits were fully applied from fiscal 2024. To respond, site operations are adopting two-day weekends, reducing nighttime work, and improving efficiency through ICT. For example, in construction management, it is becoming common to prepare and share reports on tablets and enable workers to return home directly from the site without returning to the office, thereby eliminating unnecessary travel and handwritten tasks.

Workstyle reform improves employee health and retention and contributes to securing human resources. Site work, once seen as "no time off and tough," has been gradually improving due to the changing attitudes of young engineers and DX promotion. However, without flexibility in schedules and budgets, site burdens will not decrease, which remains an issue. It is necessary to foster understanding among clients for workstyle reform and to create environments where appropriate construction periods and contract changes can be arranged. In the future, the industry is expected to aim for smart site operations with high productivity so that limited personnel can complete work within regular hours.

9. New strategies for securing and developing human resources

Amid demographic decline and aging, the construction industry faces a serious labor shortage. With fewer new entrants and an aging skilled workforce supporting sites, securing and developing human resources is an urgent issue. Companies are creating attractive workplaces by raising wage levels and improving work environments, and are also promoting environments where women and younger workers can more easily thrive on site. To develop talent capable of working in the DX era, firms are conducting internal and external training in BIM, programming, and AI utilization, aiming to cultivate a new type of skilled worker who combines traditional craftsmanship with digital technologies.

For skills transfer, efforts include compiling veteran know-how into videos and manuals for sharing, and using AR glasses to enable real-time guidance from experienced workers. In addition, collaborating with high schools and vocational schools to promote the appeal of the construction industry and attract the next generation of workers is important. The government is also providing support for young entrants and improving conditions for skilled workers; going forward, systematization of industry-wide human resource development is expected. Companies that succeed in securing and nurturing talent will be the ones with competitive strength in the future construction market.

10. Latest trends in regulations and policies

Attention must also be paid to regulatory and policy trends that support the industry's transformation. The Ministry of Land, Infrastructure, Transport and Tourism has promoted initiatives such as "i-Construction" and the "Construction DX Promotion Plan" to actively support industry-wide digitalization and labor saving. In public works bidding, bonus evaluation points for BIM/CIM utilization and ICT construction have been introduced, making companies that proactively adopt digital technologies more competitive. The amended Construction Industry Act, phased in from 2024 to 2025, includes measures to promote workstyle reform, oblige appropriate setting of construction periods, and encourage electronic contracts. This legal framework helps correct unreasonable shortcuts and low-price bids and rationalize construction systems through ICT.

Additionally, efforts are underway to popularize the Construction Career Advancement System and to standardize and open construction data. Local governments are increasingly offering their own DX and environmental support programs. Future regulatory trends are expected to include stricter carbon-neutral-related regulations (for example, mandatory submission of decarbonization plans for projects above a certain scale) and expanded support for digital human resource development. 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 the next-generation tool supporting DX, "LRTK"

Above, we explained the 10 latest trends in the civil engineering and construction industry. While these trends are distinct themes, they are interrelated and together drive industry-wide transformation. From the perspective of DX promotion and productivity improvement, attention is also focusing on new technologies like LRTK (a smartphone positioning system that combines high-precision GNSS receivers). By using LRTK, anyone on site can perform centimeter-accuracy positioning (cm level accuracy (half-inch accuracy)) without specialized surveying equipment. This not only speeds up as-built verification and land surveying, but also enables sharing positioning data in the cloud to remotely grasp progress and quality.

Thus, LRTK, a simple surveying tool combining a smartphone and GNSS, can be considered a versatile solution that contributes to multiple fields. If introduced as part of on-site DX, it can help improve construction quality, streamline surveying, and support remote assistance through real-time information sharing. The civil engineering and construction industry is now in a period of major transformation. While keeping up with the latest trends, actively adopting new technologies and tools will help us build a sustainable, high-productivity future construction industry together.
