SpatialSense 4DRC: Complete Smart Construction Solution

The construction sector operates within a highly complex landscape, filled with numerous challenges that fragmented tools alone can’t solve. At Kodifly, we designed Spatial Sense 4D Reality Capture, a complete construction tech solution that combines LiDAR, AI analytics, and seamless project collaboration into one powerful ecosystem.

What is SS 4DRC?

SpatialSense 4D Reality Capture is a complete solution for smart construction. It combines fixed-point, aerial, and handheld LiDAR based systems to deliver accurate 3D data from every angle of your site. From continuous monitoring and rapid drone mapping to detailed indoor scans, SS 4DRC ensures full visibility across the construction lifecycle, helping teams track progress, spot deviations early, and make informed decisions with confidence. It delivers continuous, automated, and intelligent site visibility that supports modern infrastructure management.

At its core, 4DRC works by capturing the physical reality of a construction site and turning it into a precise digital environment. Using a combination of LiDAR sensors, high-resolution cameras, and GNSS our system scans the entire site from multiple angles to create point cloud data, a dense collection of millions of 3D coordinates that represent every surface, structure, and object with millimeter-level accuracy. This raw data is then processed and merged into a comprehensive digital replica, often referred to as a digital twin. Unlike traditional drawings or photos, a digital twin provides a living, interactive model of the construction site that updates as conditions change. This means stakeholders can virtually walk through the site, measure dimensions, inspect progress, and identify deviations in real time without needing to be physically present. By bridging the gap between the physical and digital, 4DRC ensures that project teams always have a complete, up-to-date, and reliable source of truth for decision-making.

4DRC leverages three modes of data capture:

1. Aerial Mapping

Drones equipped with LiDAR & camera sensors capture aerial point clouds that cover large and complex sites within minutes, making it ideal for:

This mode is ideal for:

• Topographic surveys: Generating accurate terrain models before, during, and after construction.

• Progress monitoring: Comparing real-time site conditions against BIM models or schedules.

• Hard-to-access zones: Bridges, tall structures, or hazardous environments where ground teams cannot easily go.

By flying pre-programmed routes, drones ensure consistent, repeatable scans across wide areas, something impossible to achieve with manual surveys. Drone-mounted LiDAR has quickly become a key tool in construction innovation, enabling large-scale accuracy in ways traditional surveys cannot.

2. Handheld Mapping

Handheld LiDAR & camera powered scanners are used on-site by engineers or inspectors to capture close-range details that drones or fixed sensors might miss. They excel in:

• Interior spaces: Capturing layouts, structural details, and MEP systems inside buildings.

• Complex features: Recording fine geometries such as reinforcement bars, façade elements, or finishes.

• On-demand inspections: Allowing teams to instantly check areas flagged by AI or detected deviations.

This flexibility makes handheld LiDAR the “microscope” of the system, zooming into problem spots for high-resolution verification. As construction continues to adopt building tech, handheld scanning provides an agile way to digitize site details without slowing down workflows.

3. Fixed

Mounted on poles or permanent structures, fixed 4DRC LiDAR and camera sensors provide continuous, 24/7 monitoring of critical construction zones. These sensors are best for:

• High-risk areas: Excavations, crane zones, or locations with ongoing heavy machinery movement.

• Deviation detection: Automatically flagging changes in alignment, slope, or structure that deviate from design.

• Safety monitoring: Tracking hazardous conditions, such as unauthorized entry into danger zones.

By operating autonomously, fixed-point LiDAR acts as a “digital watchdog,” ensuring no changes or risks go unnoticed between scheduled inspections. Its integration into infrastructure solutions helps contractors and city planners in regions like construction in Saudi Arabia to ensure smarter, safer builds.

Applications of 4DRC

Modular Integrated Construction (MiC)

Seamlessly monitor MiC workflows, from off-site fabrication to on-site assembly, with 4D clarity. 4DRC enables precise tracking of prefabricated modules, ensuring alignment, quality, and installation accuracy.

Excavation Monitoring

Track excavation progress with high precision to ensure safety compliance and timely project delivery. The system detects deviations from design, preventing costly rework and reducing risks.

Site Formation Monitoring

Visualize terrain changes and formation stages in real time to stay ahead of site development risks. This helps teams manage earthworks efficiently while ensuring compliance with design specifications.

Operations and Maintenance (O&M)

With thermal camera integration, 4DRC extends beyond construction into long-term asset management. It enables smarter operations by detecting anomalies such as heat leaks, equipment inefficiencies, or hidden structural issues—providing a deeper level of insight for maintenance teams.

Pairing 4DRC with SpatialSense

While 4DRC provides the data capture backbone, the real intelligence comes from pairing it with SpatialSense, Kodifly’s AI-powered spatial intelligence platform. Together, they form a hardware and software ecosystem that transforms how AI is used to manage construction. Here’s how it works:

1. Multi-Modal Data Capture

   
   SpatialSense integrates data from several sources, including LiDAR, video feeds, mobile scanners, and IoT sensors tracking equipment or worker movement, making it adaptable to both construction apps and enterprise-scale platforms.

2. AI-Powered Processing

SpatialSense automatically compares LiDAR scans against BIM designs. Deviations, structural misalignments, and missing elements are instantly flagged.
The platform delivers precise, real-time measurements, volumes, areas, heights without manual calculation. This level of automation reflects the rise of automation construction, where repetitive tasks are eliminated to save both time and cost.

3. Safety Hazard Detection

Integrated computer vision scans site imagery to identify unsafe conditions: open excavations, unauthorized intrusions, workers missing PPE, or hazardous equipment movements. These hazards are overlaid directly on the 3D site model, and real-time alerts are sent to supervisors and safety teams before accidents occur.

4. BIM Integration & Automation

SpatialSense connects seamlessly with Autodesk BIM 360 and similar platforms. Deviations, inspection results, and updates are tied directly to digital twins and construction documentation. The system can auto-generate RFIs, compliance reports, and digital audit trails, simplifying handovers and ensuring regulatory compliance.

5. Real-Time Collaboration

Every flagged issue is visualized on the 3D model with precise location and severity. Built-in tools allow teams to assign responsibilities, comment, upload supporting evidence, and even host video calls all within the same environment. This reduces back-and-forth emails and ensures accountability throughout the project lifecycle.

Core Value Propositions of SS 4DRC & SpatialSense

Together, this ecosystem delivers measurable impact for construction projects:

• Reduce manual workload by up to 80% through automated scanning and reporting.

• Shorten project cycles by 50% with real-time deviation detection.

• Cut rework costs by 60% through early error detection.

• Boost safety compliance with proactive hazard alerts.

• Improve collaboration by centralizing data and communication.

• Accelerate inspections by 35% with automated LiDAR and AI analysis.

This is not just incremental improvement, it’s a fundamental shift from reactive to proactive monitoring, powered by construction innovation and building tech solutions.
