Get3D Visits CSPI-EXPO 2026

Event Date: June 17–20, 2026 | Location: Makuhari Messe, Chiba, Japan

About the Event

In June 2026, the Get3D team traveled to Japan to visit CSPI-EXPO 2026, the country’s largest national-level construction and surveying exhibition. Held at Makuhari Messe in Chiba from June 17 to 20, the event gathered over 230 exhibitors and approximately 62,000 attendees across four days — making it the most significant gathering of the Japanese construction technology industry.

Why Japan

Japan is undergoing one of the world’s most ambitious construction digital transformations. The national i-Construction 2.0 policy framework, combined with a construction workforce that has declined by approximately 30% since its 1997 peak, creates an urgent market pull for automation and digitalization technologies — including large-scale 3D reconstruction.

For Get3D, whose platform spans multi-source data fusion, automated 3D reconstruction, and digital twin creation, the Japanese market represents a natural alignment of capability and demand. Visiting CSPI-EXPO 2026 was an opportunity to gain firsthand understanding of:

  • What problems Japanese construction and surveying companies are actively trying to solve
  • How i-Construction 2.0 is translating from policy into procurement and technology adoption
  • Where 3D reconstruction technology fits into the broader Japanese construction technology ecosystem

Key Takeaways from the Exhibition

Walking the exhibition floor, attending technical presentations, and engaging in conversations with exhibitors and attendees revealed several consistent themes about where the market is heading.

Takeaway 1: The Labor Crisis Is Driving Technology Decisions

The most frequently discussed topic across the exhibition was “labor shortage”. Japan’s construction workforce has declined by approximately 30% since its 1997 peak, with workers aged 55 and above now accounting for over 37% of the industry. This is not a future forecast; it is a present-day crisis that shapes every purchasing decision.

Construction companies, surveying firms, and government agencies at the exhibition were all asking the same essential question: how can we accomplish the same work with fewer people? This translates directly into demand for technologies that automate data processing, reduce field time, and make 3D data accessible to non-specialists — areas where Get3D is positioned to deliver value.

Takeaway 2: i-Construction 2.0 Is Shifting from Policy to Procurement

Japan’s i-Construction 2.0 initiative, launched by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) in 2024 as an upgrade to the original 2016 program, has set ambitious targets: 30% on-site labor reduction and 1.5× productivity improvement by 2040. At CSPI-EXPO 2026, the policy’s impact was evident across the exhibition floor in the types of technologies being promoted and the questions being asked.

Takeaway 3: Air-Ground Fusion Is Becoming the Expected Standard

One of the most notable patterns across the exhibition floor was how many technology demonstrations involved drone + handheld + vehicle-mounted data fusion. Aerial LiDAR captures the roof and surroundings; handheld SLAM captures interiors and ground-level details; vehicle-mounted systems fill in street-level gaps.

This trend strongly validates Get3D’s air-ground fusion approach. The technology gap visible at the exhibition lies not in data acquisition hardware — the floor was saturated with scanners and drones — but in how efficiently these heterogeneous data sources can be fused into one coherent 3D reconstruction. This is exactly the problem Get3D is designed to solve: unified processing of imagery from different capture devices into complete, georeferenced city-scale models.

Takeaway 4: 3D Gaussian Splatting Is Generating Excitement — With Measured Expectations

3DGS was one of the most discussed technologies at CSPI-EXPO 2026. Multiple booths featured immersive 3DGS visualization experiences that drew consistent crowds throughout the event.

The sentiment gathered from conversations was nuanced:

  • 3DGS is enthusiastically received for visualization, stakeholder reporting, and immersive site walkthroughs — scenarios where photorealistic quality and real-time rendering deliver clear value.
  • Surveying and engineering professionals remain appropriately cautious about measurement-grade accuracy, emphasizing that 3DGS must prove itself against established photogrammetry and LiDAR workflows for compliance-critical applications.

This aligns with Get3D’s dual-output philosophy: 3DGS is not a wholesale replacement for mesh-based reconstruction, but a powerful complementary output that addresses a different set of use cases within the same project.

Takeaway 5: The Industry Is Shifting from Hardware to Platforms

Perhaps the most significant structural trend at CSPI-EXPO 2026 was the visible shift from selling individual hardware instruments to promoting integrated data platforms. Multiple exhibitors demonstrated systems that unify positioning data, point clouds, BIM/CIM models, IoT sensor feeds, and construction management dashboards into cohesive platforms.

The message was clear: hardware is the entry point, but the platform is where long-term value accrues. 3D reconstruction data must flow seamlessly into construction workflows, compliance reporting, and asset management — or its business value is limited. This validates Get3D’s platform-centric approach, where reconstruction is not an endpoint but a foundation for downstream applications.

Why These Takeaways Matter for 3D Reconstruction

Stepping back from individual technologies and conversations, CSPI-EXPO 2026 surfaced five requirements that are reshaping what the market expects from 3D reconstruction solutions:

1. Multi-source data fusion is no longer optional. The expectation is increasingly for unified models from drone, handheld, vehicle-mounted, and satellite data — not separate, fragmented datasets.

2. Processing automation determines scalability. As data capture becomes faster and cheaper, the bottleneck has decisively shifted to processing. AI-driven automation is a necessity for serving the construction market at competitive speed and cost.

3. BIM/CIM integration is becoming a baseline requirement. Japan’s move toward 3D model-based contracting means reconstruction outputs must flow into BIM/CIM workflows. Content-aware processing that understands what it is reconstructing — not just how it looks — is a competitive requirement.

4. Dual output flexibility serves real market needs. The coexistence of mesh-based and 3DGS reconstruction at the exhibition confirms that clients want both: mesh for measurement and compliance, 3DGS for visualization and communication.

5. Accessibility for non-specialists drives adoption. Japan’s tiered ICT adoption framework targets SMEs with no prior digital surveying experience, demanding cloud-based processing, intuitive interfaces, and output formats that non-technical stakeholders can use.

How This Connects to Get3D

The patterns observed at CSPI-EXPO 2026 confirm that Get3D’s technology direction is well-aligned with the needs of advanced construction markets:

  • Air-ground fusion addresses the multi-source integration demand that was the single most visible technology theme across the exhibition.
  • Dual mesh + 3DGS output from a single pipeline directly serves the market’s pragmatic approach to 3DGS adoption — use it where it shines, while retaining mesh for measurement-grade deliverables.
  • Farm Lite distributed processing targets the processing scalability challenge that the exhibition made visible: data capture is accelerating, but turning raw data into usable models at city scale remains the bottleneck.
