The Digital Revolution Comes to the Construction Site
The construction industry has long relied on craftsmanship, experience, and physical tools — from tape measures to total stations — to deliver projects accurately and efficiently. But in an era where time pressures are intense and margins are thin, precision and speed have become non-negotiable.
This is where digital reality capture and 3D modelling come into play. The
FARO Focus S70 laser scanner, when combined with modern modelling workflows, is changing how construction professionals plan, verify, and manage their sites. Together, they create an integrated process that bridges the physical world of construction with the digital world of data — making it possible to build smarter, safer, and with greater confidence.
What Is the FARO Focus S70?
The FARO Focus S70 is a compact, high-performance 3D laser scanner designed to capture precise spatial data in real-world environments. It works by emitting laser beams that bounce off surrounding surfaces and return to the device, measuring the distance, shape, and position of every point it touches.
Each scan captures millions of data points per second, creating a point cloud — a highly detailed 3D map of the site that can be accurate to within ±1 mm. The “S70” in its name refers to its scanning range of up to 70 metres, making it ideal for medium-sized building projects, refurbishments, and complex interior or façade work.
Because it’s compact, weather-resistant, and easy to operate, the FARO S70 can be deployed by surveyors, site engineers, or even project managers without specialist surveying training. Its efficiency allows teams to capture an entire site in less than an hour, creating a precise snapshot of current conditions that can be used throughout the project lifecycle.
From Point Cloud to 3D Model: Turning Data Into Insight
Once the laser scans are complete, the raw data is imported into software such as FARO Scene, Autodesk ReCap, or Leica Cyclone to clean, align, and stitch the scans together. The resulting unified point cloud forms the foundation for a 3D model of the site.
This model isn’t just a visualisation — it’s a digital twin, a data-rich representation that mirrors the exact geometry and layout of the physical environment. The model can then be imported into Building Information Modelling (BIM) software like Revit, Navisworks, or Archicad, where it becomes a powerful decision-making and communication tool.
Through this integration, 3D modelling transforms the scan data from a static record into an interactive, measurable environment. Teams can use it to perform clash detection, as-built verification, and progress tracking, or to compare real-world conditions with design intent in real time.
Real-World Applications on the Building Site
1. As-Built Verification and Quality Control
One of the most valuable applications of the FARO S70 and 3D modelling workflow is as-built verification. By scanning the structure at key project milestones, teams can compare the captured data to the design model and identify any discrepancies.
For example, imagine a structural steel frame that needs to align perfectly with pre-fabricated façade panels. Even a few millimetres of deviation can cause installation delays and rework. With laser scanning, the team can detect these misalignments immediately, long before they result in costly errors or schedule overruns.
Regular scanning also ensures consistent quality control. By maintaining an accurate digital record of progress, contractors can demonstrate compliance with tolerances, document completed works for clients, and protect themselves from disputes.
2. Refurbishment and Retrofit Projects
In renovation or retrofit projects, original building plans are often missing, outdated, or inaccurate. Traditional surveying to re-measure these spaces can be slow, disruptive, and prone to error.
The FARO S70 allows project teams to capture the entire existing structure — from complex MEP systems to architectural details — quickly and non-invasively. The resulting 3D model becomes the “as-is” foundation for redesign and planning, ensuring that every new element fits seamlessly into the existing framework.
This approach dramatically reduces the risk of encountering surprises during demolition or installation. It also supports prefabrication and modular construction, where components are built off-site and must match real-world conditions exactly when installed.
3. Progress Monitoring and Documentation
Regular 3D scans throughout a project create a chronological digital record of construction progress. This data can be compared against planned schedules or BIM models to confirm that work is proceeding as expected.
For project managers and clients, this provides an objective view of progress — not just based on reports or photos, but on measurable 3D data. It’s also invaluable for remote collaboration, allowing teams working off-site to access up-to-date visual and geometric information without visiting the location.
The digital record also serves as a long-term asset. Once the project is complete, the point clouds and models become part of the as-built documentation, providing valuable reference data for facility management, maintenance, or future expansions.
4. Health, Safety, and Accessibility
Scanning isn’t just about accuracy — it’s about safety. Traditional surveying sometimes requires personnel to access high, narrow, or hazardous areas to take measurements manually.
The FARO S70 removes this risk entirely. Its range and high-resolution capabilities allow users to capture data from a safe distance, even in confined or unstable environments. Whether documenting roof trusses, scaffolding, or excavation sites, teams can work more safely and efficiently while still achieving exceptional accuracy.
Additionally, by reducing the need for multiple site visits or physical inspections, scanning contributes to lower carbon emissions and improved site logistics, aligning with sustainability goals.
5. Improved Collaboration and Communication
3D modelling makes complex construction information accessible to everyone, not just engineers or designers. With visual, interactive models, project teams can communicate more effectively, identify potential issues early, and make decisions faster.
For instance, a client who struggles to interpret 2D drawings can easily understand a 3D visualisation of their building. Site teams can overlay the scan with the design model to visualise upcoming work or coordinate subcontractors. Even external stakeholders — such as local authorities or investors — can view models online to assess compliance or design quality.
By creating a shared digital workspace, the combination of FARO scanning and 3D modelling helps align all parties around the same source of truth.
Quantifiable Benefits: Time, Cost, and Quality
Speed
A traditional manual survey of a medium-sized building might take several days and still leave gaps in data coverage. A FARO S70 scan can capture the same area in under an hour, with data ready for modelling within a day. This speed accelerates every downstream activity — from design verification to site coordination.
Cost
Although the equipment investment may seem high initially, the savings from avoiding rework, delays, and miscommunication quickly outweigh the cost. Studies in the industry show that laser scanning can reduce rework costs by up to 50% and shorten project schedules by 10–15%.
Quality
Precision scanning ensures construction accuracy to within a few millimetres. This eliminates cumulative errors that often occur with manual measurement and ensures the final build aligns perfectly with design intent. The digital record also provides an auditable trail of compliance and progress — invaluable for quality assurance and handover.
A Glimpse into the Future: Integration and Automation
The integration of FARO scanning with BIM, AR/VR, and AI-powered analysis is pushing construction technology into new territory. Soon, site scans could be automatically analysed to detect defects, generate punch lists, or even guide autonomous equipment.
Already, contractors are combining FARO S70 data with drone photogrammetry and ground-penetrating radar to create multi-layered digital twins — capturing both what’s visible and what’s hidden underground. This holistic approach transforms project management from reactive to predictive, enabling real-time decision-making based on accurate site intelligence.
Conclusion: Building Smarter with Digital Precision
The FARO Focus S70 and 3D modelling are more than just tools — they represent a fundamental shift in how the construction industry captures, communicates, and delivers work. By turning complex physical environments into data-rich digital twins, they empower teams to work faster, safer, and with greater precision than ever before.
From early design validation to final handover, the integration of laser scanning and 3D modelling enhances every stage of the project lifecycle. It reduces risk, improves collaboration, and sets a new benchmark for quality and accountability.
As the construction sector continues to embrace digital transformation, those who adopt this technology today will be the ones setting the standards tomorrow. The combination of the FARO Focus S70 and intelligent 3D modelling isn’t just a technological upgrade — it’s the foundation of the next generation of building site management.
