On-site logistics in construction: still stuck on paper and fax?
Labor management, design changes, safety checks, passing on know-how — when on-site logistics are tied to paper and fax, the construction work itself grinds to a halt. Cor. walks with you toward the next step, matched to your on-the-ground challenges.
01 / Common Challenges
The "reasons things stall" we often hear on construction sites.
The limits of labor management and keeping projects on schedule under the overtime cap (the "2024 problem")
On-site reality
Although the regulation from April 2024 set strict caps on overtime, the structural pressures on site — short-deadline orders, weather delays, and more — haven't changed.
If left unaddressed
Site managers end up forced to absorb the work by taking paperwork home, leading directly to burned-out staff leaving and to project delays.
Real-time gaps between drawings/BIM data and the site caused by frequent design changes
On-site reality
Every time a design change happens on site, the latest drawings and BIM data don't reach craftspeople and partner firms quickly enough, raising the risk of construction errors based on outdated information.
If left unaddressed
"Rework" (rebuilding) on the scale of millions to tens of millions of yen occurs, which not only squeezes costs but also causes major schedule delays.
Daily safety checks (KY activities) becoming a formality, and insufficient safety training for an increasingly multinational workforce
On-site reality
Daily hazard-prediction (KY) activities tend to become routine, with paperwork reduced to copy-paste. And as the number of foreign workers grows, there's a challenge in getting Japan's safety rules across accurately, down to the context.
If left unaddressed
The risk of serious workplace accidents rises, which can lead to grave consequences such as halted operations on site and a loss of corporate social trust.
The break in proprietary construction techniques and know-how as veteran craftspeople age and retire
On-site reality
With veterans in their 50s and older making up a large share, the techniques aren't written down or turned into manuals, and passing them to younger workers still relies on the person-dependent "watch and learn" approach.
If left unaddressed
The trades and unique strengths you can handle in-house are lost, leading to weaker competitiveness in winning future work and even the disappearance of the techniques themselves.
02 / How Cor. Walks With You
Here's how Cor. walks with you.
We move forward together, combining AI contract development, AI advisory, local LLM, and Grift to fit each challenge. We don't deal in certainties — we value walking alongside you in a way that fits the realities on the ground.
- AI contract development
Schedule simulation and visualization of operation logs
We work with you to build setups for calmer site operations — reworking complex schedules and gently detecting bottlenecks from each site's operation logs.
- AI contract development
Automatic extraction of changes and instant suggestions to stakeholders
We compare updated drawing and spec data and have AI summarize and extract the key changes in an easy-to-grasp way. We help build an environment to reliably relay and share them with stakeholders, drawing on our experience implementing drawing processing.
- AI contract development
Context-aware hazard prediction and high-accuracy multilingual translation
We walk with you toward safe team-building on site — with AI suggesting concrete hazard-prediction hints for the day's trade and weather, and high-accuracy multilingual translation that captures the nuance of safety manuals.
- Local LLM & secure AI
Structuring on-site know-how and building a skill-assist environment
We organize veterans' work videos, past construction records, and trouble-response logs into a form AI can learn from easily. We support a setup where younger workers, when they hit a question on site, can draw on the organization's knowledge base.
Start by framing how to use AI on confidential data.
We help you decide where to begin under industry constraints. You can also review how Grift builds estimate rationale.
Grift outputs are reference estimates before consultation. Formal price and schedule are confirmed after requirements review.
