Why is i-Construction 2.0 important? Explaining construction DX in 5 key points

i-Construction 2.0 is not merely a policy to increase the use of ICT construction machinery and 3D surveying. It is a new direction announced by the Ministry of Land, Infrastructure, Transport and Tourism in April 2024, and an approach to automate the three areas of construction, data integration, and construction management collectively, with the goal of reducing labor on construction sites by at least 30%, that is, increasing productivity to 1.5 times, by fiscal year 2040. What is important for practitioners searching for i-construction 2.0 is that this policy is likely to change the assumptions underlying future procurement conditions, site operations, required personnel, and data preparation. Ministry of Land, Infrastructure, Transport and Tourism

Conventional i-Construction has, since 2016, promoted productivity improvements across the entire construction production process, and the productivity improvement ratio for directly managed projects, using the reduction in working hours achieved by ICT-based construction as an indicator, reached approximately 21%. Building on that, i-Construction 2.0 elevates its focus from the previous "use of ICT and other technologies" to "automation," and, with an eye to future labor shortages and infrastructure maintenance, aims to advance construction DX to the next stage. This article organizes why i-Construction 2.0 is important into five key points directly connected to practical work. Ministry of Land, Infrastructure, Transport and Tourism

What is i-Construction 2.0?

i-Construction 2.0 is a policy package to automate the construction site itself in order to sustain infrastructure development and maintenance even under population decline. At its core is not merely automating construction machinery, but linking design, construction, and supervision and inspection through data to transform sites into places where a small workforce can work safely and comfortably. In other words, it needs to be regarded not as the one-off introduction of digital tools, but as a redesign of the entire construction production process. Ministry of Land, Infrastructure, Transport and Tourism

What sets this policy apart from the conventional i-Construction is that its purpose is not limited to mere productivity improvement measures but is explicitly positioned as a measure to reduce the need for personnel. The Ministry of Land, Infrastructure, Transport and Tourism states that, in order to sustainably protect infrastructure amid population decline, it is necessary to further accelerate the use of ICT to date and advance toward automation. The objectives include not only productivity improvement but also ensuring safety, work style reform, securing diverse human resources, and realizing an attractive construction industry.

Ministry of Land, Infrastructure, Transport and Tourism

The three pillars presented are automation of construction, automation of data linkage, and automation of construction management. The first pillar consists of initiatives to change on-site work itself through remote construction, automated construction, and the use of construction data. The second pillar consists of initiatives to connect BIM/CIM and three-dimensional data across design, estimation, factory fabrication, construction, and inspection. The third pillar consists of initiatives to transform supervisory inspections and management tasks through remote site presence, digital inspection, and off-site processes; it is important to view the three not separately but as mutually interlinked.

Why i-Construction 2.0 Is Important Now

The main reason i-Construction 2.0 is being emphasized is that the balance between workload and the workforce will further deteriorate going forward. The Ministry of Land, Infrastructure, Transport and Tourism expects the working-age population to decline by about 20% in fiscal year 2040 compared with fiscal year 2020, while the proportion of facilities—such as roads and bridges, tunnels, rivers, water supply, sewerage, and ports—constructed since the period of high economic growth that will be more than 50 years old will increase rapidly. With the burden of not only new construction but also maintenance and renewal growing, the starting point of 2.0 is the recognition that continuing on the same personnel assumptions as before will no longer be sustainable. Ministry of Land, Infrastructure, Transport and Tourism

Furthermore, the construction industry is characterized by outdoor work and a high proportion of one-off production, making it difficult to standardize conditions as in a factory. Even in materials from the Ministry of Land, Infrastructure, Transport and Tourism, it is noted that, given these characteristics, improving productivity at construction sites cannot be achieved overnight. That is why superficial DX that merely installs software or distributes devices is insufficient; operational design that includes site planning, machinery, data, and supervision and inspection is required.

Ministry of Land, Infrastructure, Transport and Tourism

The important point is that i-Construction 2.0 has already begun moving out of the conceptual stage and into the implementation stage. In the Ministry of Land, Infrastructure, Transport and Tourism’s FY2025 materials, measures are indicated such as expanding pilot projects for automated construction, establishing procurement rules for remote construction, formulating BIM/CIM handling guidelines, trials to utilize 3D models as contract documents, and digitizing construction management. In other words, whether you take action now is likely to create differences in bidding competitiveness and on-site operational capability a few years from now.

Ministry of Land, Infrastructure, Transport and Tourism

From a practical standpoint, i-Construction 2.0 is not a question of "whether to use new technologies." It is fundamentally a management issue of which projects, at what quality, and how stably can be run with limited personnel. If waiting times, travel time, paperwork, rework, and hazardous tasks—absorbed until now by individual efforts on site—are left as they are, they will become the first bottlenecks when labor shortages deepen. In that sense, 2.0 should be regarded not as an idealistic theory of construction DX but as a realistic measure to protect future supply capacity. Ministry of Land, Infrastructure, Transport and Tourism

Key Point 1 Construction automation will become the core of labor-saving

Among the five key points, the most central is the automation of construction. The Ministry of Land, Infrastructure, Transport and Tourism is promoting two-way, real-time use of site-acquired data fed back to construction machinery, aiming in the short term to realize construction that utilizes construction data in real time, in the medium term to standardize automated construction under certain conditions, and in the long term to achieve automated and optimized construction on large-scale sites. The essence here is not to make individual construction machines smarter, but to change the situation so that the overall construction capability of a site can be maintained with a small workforce. Ministry of Land, Infrastructure, Transport and Tourism

This trend is already taking shape. The Ministry of Land, Infrastructure, Transport and Tourism formulated safety rules for automated construction in March 2024, and in fiscal 2024 carried out four pilot construction projects at actual sites. In fiscal 2025, it plans to continue pilot projects and expand the types of construction covered. In other words, preparations concerning safety, operations, and standards—the prerequisites for on-site implementation—are being advanced in parallel, moving one step beyond the stage of "the technology is interesting but the regulations can't keep up."

Ministry of Land, Infrastructure, Transport and Tourism

Remote construction is no longer a technology limited to disaster response. According to the Ministry of Land, Infrastructure, Transport and Tourism, in fiscal 2024 there were 21 cases of remote construction carried out on projects commissioned by the ministry, including routine construction, and in fiscal 2025 the ministry is advancing the establishment of rules regarding the contracting of works to promote further use. This trend not only enables unmanned operation at hazardous locations but also reduces travel burdens, allows wider deployment of experienced operators, and leads to redesigning arrangements for night-time and long-duration construction.

Ministry of Land, Infrastructure, Transport and Tourism

Furthermore, the automation of construction is not intended to aim for completely unmanned operations from the outset. The Ministry of Land, Infrastructure, Transport and Tourism is shifting part of ICT earthworks and ICT dredging to a client-designated model and plans to make ICT construction the standard from fiscal 2025. In other words, the approach is staged: first establish an environment in which construction data can be reliably captured, and then link that to remote and automated construction. Because automation and optimization cannot be achieved at sites where data cannot be collected, this sequence is very practical. Ministry of Land, Infrastructure, Transport and Tourism

What should be considered on-site is "where automation will be most effective." By starting with processes that are highly repetitive, have clear work boundaries, and whose progress and operational status can be easily captured as data, the effects become easier to see. Areas that are easy to quantify, such as earthwork, hauling, and as-built measurement, are a good fit, whereas processes with many exception-handling cases are more likely to be successfully adopted if you first introduce remote assistance or semi-automation. What is important in construction automation is not increasing the number of machines, but changing the setup and division of roles.

Key Point 2 Data integration automation reduces rework and duplicate data entry

What tends to be overlooked in construction DX is the magnitude of waste generated by data handovers, rather than by the construction work itself. In materials from the Ministry of Land, Infrastructure, Transport and Tourism, the aims of i-Construction 2.0 are repeatedly shown to include eliminating the "duplicate effort in data creation" and reducing rework. The reason sites are struggling is not only a shortage of personnel, but also that the same information is repeatedly recreated, transcribed into different formats, and reinterpreted in downstream processes. Ministry of Land, Infrastructure, Transport and Tourism

For this issue, BIM/CIM is positioned at the core of data integration. The Ministry of Land, Infrastructure, Transport and Tourism has applied BIM/CIM in principle from fiscal 2023, and states that standardization of 3D design and data utilization are indispensable for future improvements in design efficiency and construction automation. On the other hand, it clarifies current challenges: the data required at each stage is not clearly defined, 2D drawings and 3D models are not linked, and 3D models tend to remain merely reference materials. Unless this changes, models will end up as attractive-looking documents and workloads will not be reduced. Ministry of Land, Infrastructure, Transport and Tourism

Therefore, the Ministry of Land, Infrastructure, Transport and Tourism is promoting mechanisms to directly apply quantities calculated by 3D models and design-support software to quantity takeoff and cost estimation, and mechanisms to connect design data to ICT construction machinery and factory fabrication. Furthermore, through construction simulations using digital twins and 4D models, it is indicating a direction toward sharing construction visualization among all stakeholders and thereby preventing rework and errors. In other words, the automation of data linkage should be understood not as merely storing design data, but as standardizing it into a form usable in downstream processes and feeding it into actual decision-making and work.

Ministry of Land, Infrastructure, Transport and Tourism

In FY2025 initiatives, this direction has been further specified. As a premise for utilizing 3D models as contract documents, 86 initiatives were implemented to make coordination with 2D drawings a principle, and in FY2025 the formulation of consistency-check rules, trials of using 3D models as contract documents, and reductions in the effort required to produce 2D drawings are planned to be advanced. BIM/CIM quantity estimation using attribute information was also piloted in FY2024 on 11 bridge substructure works, and an expansion policy has been indicated for FY2025. This means that the boundaries between design and quantity estimation, and between design and construction, are beginning to change gradually.

Ministry of Land, Infrastructure, Transport and Tourism

When implementing this in-house, the important thing is not to start by building complex models. First decide the coordinate system, attribute fields, file-naming conventions, rules for managing photos and point clouds, who inputs what at each stage, and what will be used in the next process. The success or failure of data linkage depends less on differences in software capabilities and more on how well you can establish rules that can be operated consistently inside and outside the company. The turning point is whether you can convert BIM/CIM from a "visualization tool" into "operational data that can be reused in downstream processes."

Key Point 3: Automation of construction management is changing supervisory inspections

Among the three pillars of i-Construction 2.0, the automation of construction management is the measure most likely to produce a tangible change for site personnel. The automation of construction management referred to here is not simply shifting to online meetings. It means streamlining management activities such as on-site attendance, phase checks, supervisory inspections, as-built checks, and quality checks through remote and digital methods so that the right people can concentrate on the decisions they need to make.

Ministry of Land, Infrastructure, Transport and Tourism

The Ministry of Land, Infrastructure, Transport and Tourism has made remote on-site inspections—using cameras and web communications to carry out checks without traveling to the site—the default practice for witnessing and stage verifications since fiscal year 2022, and has expanded them to interim technical inspections and completion inspections from fiscal year 2024. This broadens the foundation for conducting necessary checks while reducing the burden of travel time and schedule coordination. The automation of construction management is not about supervisors no longer going to the site, but about enabling them to narrow down the situations in which they need to visit the site. Ministry of Land, Infrastructure, Transport and Tourism

Furthermore, the digitization of supervision and inspection is also progressing. In the Ministry of Land, Infrastructure, Transport and Tourism’s materials for fiscal year 2025, it is shown that the guidelines were revised so that preparation and submission of as-built management charts are unnecessary when as-built surface management data are overlaid on-site to carry out supervision and inspections. In addition, trials to digitize and reduce labor through image analysis of ready-mix concrete slump began in nationally directly managed projects from fiscal year 2023, and eleven trials were conducted in fiscal year 2024. This represents a move to replace paper documents for inspections with the digital data themselves as inspection evidence. Ministry of Land, Infrastructure, Transport and Tourism

The practical implications are significant: the focus of construction management shifts from "creating documents" to "detecting anomalies quickly." By combining data-sharing infrastructure, BI tools, AR, image analysis, and point cloud data, supervisors and construction workers can more easily verify the same phenomena on a shared screen, reducing omissions in records and transcription errors. As a result, there is potential to reduce the time spent on travel, waiting, and organizing paperwork without lowering the quality of inspections. Ministry of Land, Infrastructure, Transport and Tourism

However, a common pitfall is that, even after shifting to remote operations, only the audit-trail rules are left stuck in the paper era. If you don't design camera positions, timing of capture, data storage, approval workflows, and methods for recording who made which decision at what point, you risk increasing the workload for both the field and the office. Automation of construction management must be pursued not as the introduction of communication devices, but as a redesign of the verification tasks themselves.

Key Point 4: Ensuring Safety and Work-Style Reforms Lead to Securing Human Resources

i-Construction 2.0 is not just about productivity. The Ministry of Land, Infrastructure, Transport and Tourism clearly sets as its goals ensuring safety, workstyle reform, securing a diverse workforce, and realizing a construction industry that offers hope. Minimizing the risk of harm to people, enabling work to be carried out in comfortable environments, and expanding flexible workstyles that make effective use of time and place are built into the policy objectives from the outset. If construction DX is understood merely as a cost-cutting measure, this essence will be lost. Ministry of Land, Infrastructure, Transport and Tourism

For example, if automation at construction sites advances, some tasks that were previously carried out under the blazing sun or in hazardous locations can be performed from indoors or from remote operation rooms. The Ministry of Land, Infrastructure, Transport and Tourism has also indicated that sharing BIM/CIM data in the cloud can reduce ad hoc responses by both clients and contractors and lead to more flexible ways of working that make more effective use of time and place. Remote construction management and supervisory inspections, the use of precast elements, and off-site construction are not merely means of improving efficiency but are also ways to create workplaces where people can continue to work more easily. Ministry of Land, Infrastructure, Transport and Tourism

This change also alters the profile of required personnel. A 2025 Ministry of Land, Infrastructure, Transport and Tourism document indicates implementation of programs to develop automated-construction coordinators within companies and the training of operators with knowledge and skills in remote construction. In fiscal 2024, 30 unmanned-construction training sessions were held at regional development bureaus nationwide, with a total of 1,018 people attending. In other words, what is required is not only people who stay on site for a long time, but personnel who can understand the site, data, and machines across those domains and connect multiple processes. Ministry of Land, Infrastructure, Transport and Tourism

From the standpoint of recruitment and development, this direction is actually an opportunity. If some tasks that have traditionally tended to depend on physical strength and years of experience are replaced by monitoring, analysis, planning, remote support, and data management, there will be broader opportunities for younger workers, women, those with experience in other industries, and staff based at regional locations to play active roles. Enhancing the appeal of on-site work requires not only improving salaries and leave systems but also addressing how much dangerous and arduous work can be reduced. The emphasis on i-Construction 2.0 stems from this context of securing personnel. Ministry of Land, Infrastructure, Transport and Tourism

On the other hand, this does not mean that people will become unnecessary. Rather, what matters is how on-site experience is translated into data, how it is standardized, and how it is preserved as a basis for decision-making. Rather than denying the intuition and experience of skilled workers, converting those into reproducible rules and data to maintain organizational construction capabilities is indispensable for construction DX in an era of labor shortages.

Key Point 5: Phased implementation with an eye toward 2040 will determine the success or failure of construction DX

Another important point of i-Construction 2.0 is that it sets out a roadmap looking toward 2040. The Ministry of Land, Infrastructure, Transport and Tourism has indicated that it plans to progressively advance automation of construction, data linkage, and the remote and off-site management of construction on short-, medium-, and long-term timeframes. This is not a claim that all sites will immediately become fully unmanned; it should be understood as a plan that organizes what should be prioritized next as a continuation of current efforts. Ministry of Land, Infrastructure, Transport and Tourism

In the short term, relatively practical themes line up, such as real-time utilization of construction data, expansion of remote construction, standardization of BIM/CIM attribute information, and the extension of remote site attendance and digital inspections. In the medium term, standardization of automated construction under certain work types and conditions, 3D design standardization, and the full-scale use of digital twins in construction planning are expected. In the long term, goals include realizing automated and optimized construction at large-scale sites, carrying out decision-making work from comfortable offices, and achieving more advanced data integration. Because phased implementation is assumed, it becomes easier to set priorities for each site. Ministry of Land, Infrastructure, Transport and Tourism

What is important here is not to try to change the entire process at once. If you rush automation of construction, safety rules, the communications environment, machine data, and the mechanisms for verifying as-built conditions will not keep up, and it can actually cause more confusion. Conversely, if you first put in place data acquisition for surveying, as-built checks, and construction management, reduce travel and paperwork through remote site presence and digital inspections, and only then move on to construction data integration and automation, the return on investment becomes easier to see. Phased implementation is not a compromise but a design to reduce the probability of failure.

In practice, when setting KPIs, it is more realistic to start with indicators such as data acquisition rate, reduction rate of re-entry, site round-trip time, inspection documentation preparation time, visibility rate of machine operation, and number of rework cases, rather than with a completed automation rate. The value of i-Construction 2.0 lies not only in the ultimate ideal, but in how much waste can be eliminated and construction capability maintained during the interim stages on the way there.

How to implement i-Construction 2.0 in practice

When translating into practical operations, the first thing to do is not technology selection but to clarify which wastes you want to reduce. Whether the issue is waiting time, travel time, the heavy burden of preparing as-built or quality reports, or the burden of data corrections when design changes occur, the pillars to prioritize will differ. In materials from the Ministry of Land, Infrastructure, Transport and Tourism, reducing on-site waiting time, reducing duplicate work, preventing rework, and going paperless are organized as concrete objectives, so you first need the perspective of mapping your company's bottlenecks to those objectives.

Ministry of Land, Infrastructure, Transport and Tourism

Next, it's important to standardize the data foundation, even if it's small. If you don't decide on coordinates, attributes, delivery rules, how to handle photos and point clouds, who inputs data and when, who verifies it, and what will be considered the authoritative data, later attempts to connect construction machinery, remote site attendance, inspection apps, and integration with estimating systems won't align. In construction DX, having equipment on site is less directly tied to results than having consistent rules for information handover.

On that basis, set up a pilot that makes it easy to measure effects. For example, choose processes that involve repeated work of the same kind and where differences in site conditions are relatively small, and measure work time, travel time, time spent creating forms, the number of rework cases, and inspection time before and after implementation; this makes decision-making easier. The Ministry of Land, Infrastructure, Transport and Tourism itself has been revising procedures and rules while repeating trial construction and trial operations, proceeding on the premise of trying and correcting rather than assuming a perfect system exists beforehand. Ministry of Land, Infrastructure, Transport and Tourism

Finally, a review of role allocation, including subcontractors, is indispensable. Even if only part of design, surveying, construction, machinery, or supervision and inspection is digitized, the overall process cannot be optimized if the upstream and downstream processes remain analog. Aligning in advance—including the site representative, supervising engineer, surveying staff, ICT staff, subcontractors, and the client's reviewers—on who will use which data and when is a condition for preventing i-Construction 2.0 from remaining mere rhetoric.

Common challenges during implementation

One common issue that arises with the introduction of i-Construction 2.0 is that, even though 3D data are created, the workload does not decrease. The Ministry of Land, Infrastructure, Transport and Tourism also points out that, at present, because 3D models and 2D drawings are not linked, 3D models remain merely reference materials and cannot be fully utilized as contractual documents. When creating models becomes an end in itself, sites end up having to manage both the traditional documents and the new models, resulting in duplicated management. Ministry of Land, Infrastructure, Transport and Tourism

The second is that, despite remote operations, the burden of supervision and inspection does not decrease. Even if there are systems for remote attendance and the utilization of digital data, if procedures, approvals, audit trails, and the handling of forms remain as before, inefficiencies remain: collecting data on site, preparing separate documents in the office, and then organizing them on paper. The Ministry of Land, Infrastructure, Transport and Tourism’s move to make the submission of as-built management charts unnecessary, among other measures, shows that simply introducing equipment is not enough — management rules must also change for it to have meaning.

Ministry of Land, Infrastructure, Transport and Tourism

The third is that machines and systems are isolated at each site and cannot interoperate. The Ministry of Land, Infrastructure, Transport and Tourism is promoting consideration of a common data environment that aggregates and utilizes construction data, common rules for API integration, and even common control signals that would allow machines from different manufacturers to run the same programs. In other words, what will become important in the future is not just individual performance but the connectivity of different equipment and data. Companies also need to have selection criteria from the outset that assume data portability and reuse. Ministry of Land, Infrastructure, Transport and Tourism

The fourth issue is that the definition of personnel roles is ambiguous. Behind the push to develop automated construction coordinators and remote construction operators is the reality that, more than the technology itself, there is a shortage of people who can oversee implementation, operation, and improvement. If the system is introduced without deciding who will check data quality, who will decide on remote responses, and who will connect the site and the office, work will ultimately become concentrated among a small number of specialists. It is essential to review job design at the same time as introducing the technology.

Ministry of Land, Infrastructure, Transport and Tourism

Summary

The reason i-Construction 2.0 is important is clear. With population decline and aging infrastructure progressing simultaneously, construction sites cannot be maintained using the same manpower-intensive methods as before. As a solution, the Ministry of Land, Infrastructure, Transport and Tourism aims to achieve a 30% reduction in labor and a 1.5 times increase in productivity by fiscal year 2040, and intends to advance, as an integrated effort, automation of construction, automation of data integration, and the remote and off-site management of construction. In other words, i-Construction 2.0 is not a buzzword for construction DX but an implementation plan to sustain construction capacity into the future.

Ministry of Land, Infrastructure, Transport and Tourism

The five key points to keep in practice are placing construction automation at the center of labor-saving efforts, eliminating duplicate work through data integration, shifting supervision and inspection to a digital-first basis, linking safety assurance and work-style reforms to personnel retention, and implementing measures in phases with 2040 in mind. In particular, for companies where the acquisition of 3D data and its connection to on-site operations serve as the entry point for adoption, the next issue will be how to implement positioning and measurement on site, and in that context attention should naturally focus on site-based systems such as LRTK.

If you are going to respond to i-Construction 2.0, the quickest route is to first visualize which of the waiting times, movements, data re-entry, rework, or creation of paper documents occurring at your sites is the heaviest, and then start small from there. The policy direction is already clear, and trials and rulemaking are progressing. What is needed now is not to wait for everything to change someday, but to break it down into forms that can be reproduced at your own sites and implement them one by one.
