Summarizing the i-Construction policy in one sentence

What is i-Construction in the first place?

The problem awareness that became the starting point for the policy

Background 1 Population decline and shortage of workers

Background 2 Lagging productivity improvements at worksites

Background 3 Need for safety assurance and work-style reform

Background 4 Full-scale digital transformation of infrastructure

When these three directions are taken together, the i-Construction policy is not completed by mechanizing the site itself alone. It also includes reducing information discrepancies between design and construction, promoting factory prefabrication and standardization, and correcting the uneven concentration of construction schedules, thereby preparing the prerequisites for sites to operate without undue strain. For that reason, while i-Construction is a measure of construction technology, it is also strongly linked to revisions in procurement and institutional operations.

Policy 1 Full utilization of ICT

Policy 2 Introduction of overall optimization

Policy 3 Smoothing of construction schedules

This is because, no matter how much ICT or automation is advanced, if project timelines are set too tightly or construction orders concentrate in specific periods, sites tend to revert to manpower-intensive methods. Smoothing is the groundwork to ensure that technology adoption takes hold properly at worksites. The i-Construction policy is an approach that changes not only machines and software but also the premises of workstyles and construction management.

Why is it i-Construction 2.0 now?

The three pillars of i-Construction 2.0

The current position as seen from FY2025 initiatives

How will worksites change under this policy?

Next to change will be human roles. In i-Construction 2.0, by promoting automated and remote construction, people are expected to shift their focus from direct work at hazardous locations to monitoring, decision-making, and management. This does not mean skilled techniques will become unnecessary, but that the way skills are applied will change. The more experienced workers at sites are likely to move into roles where they oversee multiple processes remotely or optimize sequencing based on data.

Worksite management will also change. As indicated in ICT construction Stage II, if the idea of visualizing the status of machines and tasks with data and rethinking the allocation of personnel and resources to optimize sites spreads, management will take a step beyond reliance solely on intuition and experience. The i-Construction policy is moving toward changing the very premises of management, not merely assisting site management through digitization.

What it means for small and medium construction companies and municipalities

It also has great significance for municipalities. As technical staff shortages progress, it becomes difficult to carry out supervision and maintenance in the traditional manpower-dependent way. If standardization of 3D data, remote verification, and accumulation of construction data advance, clients will also find it easier to ensure quality and conduct maintenance with a limited number of people. i-Construction is a policy that supports the sustainability of public procurement and regional infrastructure operation, not just contractors.
