What is i-Construction 2.0

In short, i-Construction 2.0 is a policy aimed at transforming construction sites—building on the ICT adoption achieved so far—from places that only function when many people are constantly present into sites that can be operated safely, continuously, and with assured quality by a smaller number of personnel. Under i-Construction since fiscal 2016, the major goal was to utilize ICT across the entire construction production process—from surveying to design, construction, inspection, and maintenance—and to improve productivity by 20% by fiscal year 2025. By contrast, 2.0 centers on changing the way sites are operated—not just using digital devices but including automation, remote operations, and data linkage.

Why is the transition to 2.0 necessary now

Differences from the conventional i-Construction

Looking at the differences between the conventional i-Construction and 2.0 from a practical perspective, the first difference is goal setting. The conventional approach focused on widely introducing ICT devices and 3D data into the construction production process and improving productivity by 20% by fiscal year 2025. In contrast, 2.0 aims for at least a 30% reduction in labor—i.e., 1.5 times productivity—by fiscal year 2040, targeting more long-term and structural changes that include safety assurance and work-style reform. The shift is from single-year labor savings and partial optimization to sustainable site operations that assume population decline.

The second difference is the placement of means. The conventional approach emphasized “using ICT to improve the efficiency of human tasks,” with a focus on 3D surveying, ICT construction machinery, 3D design data, and digitalization of as-built management. 2.0 goes a step further by explicitly promoting “automation of construction itself,” “automation of data linkage from design through construction to inspection,” and “automation of construction management including supervision, inspection, documentation, and verification.” Practically speaking, the stage has advanced from people manually linking each process to data and machines autonomously connecting processes as much as possible.

The third difference is the scope. If the conventional i-Construction is understood as an extension of “ICT earthwork” or “drone surveying,” 2.0 can appear to be just about advanced heavy machinery. In reality, 2.0 targets the entire flow of information connecting procurement, design, surveying, supervision, inspection, and maintenance as well as construction. The formalization of BIM/CIM principles and the idea of data sharing become important for precisely this reason. Whether the 3D data used on site remain one-off temporary files or become assets that can be handed to subsequent processes will be the dividing line in the 2.0 era.

The three pillars of i-Construction 2.0

The second pillar is automation of data linkage. The important point here is to handle 3D data and design information not as isolated items at surveying, design, construction, and inspection stages, but in a connected form as much as possible. Formalizing BIM/CIM underpins this flow institutionally. Passing surveying results to design, applying the design model in construction, and linking construction records to inspection and maintenance— the smoother this chain becomes, the fewer duplicate entries, transcription errors, discrepancies between drawings and the actual site, and redundant document preparations will occur. What 2.0 requires is less about whether advanced software has been introduced and more about whether site data are in a state that allows reuse in the next process.

These three pillars may appear separate, but they are actually closely connected. Even if you try to automate construction, machines cannot operate correctly if the underlying design or terrain data are fragmented. Even if the data are organized, if supervision and inspection remain based on physical presence and paper as before, overall labor savings will not advance. Conversely, companies that can view surveying, stakeout, construction, as-built, and inspection as a single data flow will transition to 2.0 more quickly. Understanding i-Construction 2.0 means looking at the connectivity of the entire process rather than the advancement of individual technologies.

How the work of practitioners will change

The biggest change for practitioners is that the substance of “working hard on site” will change. Traditionally, sites have functioned because different people—those who measure, those who revise drawings, those who set out positions, those who take photos, and those who compile documents—each did their best at each stage. In 2.0, reducing ad-hoc responses is emphasized by producing data from the start that can be reused by later processes. Therefore, what will be valued going forward are not only those with long field experience, but people who understand coordinate systems, 3D data, attribute information, and handover conditions, and who can link data across the entire process.

Roles for personnel will also change. Initiatives planned for fiscal 2025 include organizing the knowledge and skills required to introduce automated construction and creating programs to train automated construction coordinators. This indicates that the future field worker will need not only skills to operate machines individually, but also the coordination ability to combine multiple technologies, design the overall site operation, and realize remote construction and data linkage. The boundaries between construction management, surveying, design, and information management will become more blurred than before.

Another point not to be overlooked is that the quality of interactions between clients and contractors will change. Until now, in many cases it was sufficient to translate information obtained on site into drawings or photo reports at the end. But in 2.0, because it is important to hand over obtained data in a state that is easy to use in the next process, it becomes increasingly necessary to align in advance on deliverable granularity, attributes, update history, and sharing methods. In practice, the mindset required is not to compile materials after the site is finished, but to prepare from the start of the work with the awareness of “who will use which data next.”

Common misconceptions in implementation

One common misunderstanding when discussing i-Construction 2.0 is the view that “it is about immediately aiming for complete unmanned operation.” Of course, unmanned operation and automation are important as a future direction, but current public documents show that what is progressing first are expanded trials of remote construction, preparation of procurement rules, safety rule development, creation of data-sharing infrastructure, and human resource development. In practice, rather than automating everything at once, a realistic phased introduction is to remove people from hazardous tasks, increase remotely operable processes, and link data to reduce rework.

Another misconception is the idea that “installing new machines or new software will make it 2.0.” The essence of 2.0 is not single-item adoption but considering the data flow from input to output consistently. For example, introducing high-performance measurement equipment may actually increase site burden if coordinate handling is ambiguous, naming and update rules for deliverables are not unified, and the results cannot be reused in design or construction. Conversely, even on a small scale, if surveying, stakeout, as-built, and inspection can circulate the same standard of data, substantial progress toward 2.0 can begin. The fact that regulations consider small-scale sites and mobile device usage is for this reason.

How to proceed on site

So, where should you start in practice? The recommendation is not to aim immediately for full automated construction, but first to organize the data input. Can the current situation be captured quickly, accurately, and in a form usable by subsequent processes? Can coordinates, photos, point clouds, as-built data, and design data be kept together at the site level and handed to the next process? If you proceed to remote construction or automation without this foundation, human correction and verification will increase and expected labor savings will not materialize. The essence of 2.0 is not adding more machines, but building an information foundation that reduces rework and duplication.

In addition, when implementing changes on site, it is important not to treat technology introduction as a one-off event. If only the surveying team understands 3D data, the design team recreates it in a different format, the construction team converts it back to paper, and the inspection team again organizes photos and reports manually, the effect of 2.0 will be limited. What is more important is to review the flow from current-condition capture, design reflection, construction instructions, as-built confirmation, to inspection documentation as a single business process. Simply identifying where the same information is entered redundantly and where coordinates or attributes are lost will make the improvement points toward 2.0 quite clear.

Summary

i-Construction 2.0 does not reject the conventional i-Construction; rather, it is the next stage that layers automation, data linkage, and remote operations on top of the ICT-enabled foundation so that sites can be operated safely with fewer people. The essential difference is not old tools versus new tools, but whether site work is run by “adding manpower” or by “data and systems.” What will be required of practitioners going forward is not only the skillfulness of individual tasks, but the perspective to design the flow of information connecting surveying through construction management. Responding to i-Construction 2.0 does not start with a large-scale investment someday; it begins by standardizing how coordinates and 3D data used on site are handled. To take that first step reliably, it will become increasingly important to utilize easy-to-use high-precision positioning systems like LRTK and to smoothly cycle measuring, aligning, and recording in daily operations on construction sites.
