Time is money, and schedules are tighter than ever in today’s construction industry—especially on larger projects, where tight tolerances, complex systems, and the need for seamless coordination across trades leave little room for error. But there are new tools available that can make a significant impact toward delivering projects on time and on budget. Hexagon Building Solutions’ automated Deviation Analysis service transforms how general contractors (GCs), owners, and subcontractors approach quality assurance, risk mitigation, and as-built documentation.
What is Hexagon Buildign Solutions’ Deviation Analysis?
Hexagon’s Deviation Analysis is an automated solution using 3D laser scanning and Building Information Modelling (BIM) data to detect construction deviations and potential future system clashes. Designed for complex projects such as hospitals, airports, data centers, laboratories, and pharmaceutical manufacturing facilities, this solution provides actionable insights into construction quality and accuracy throughout the project lifecycle.

How does Deviation Analysis work?
Multivista reality capture specialists come onto your project site and capture as-built conditions with top-quality Leica 3D scanners. By comparing that as-built scan data against 3D design intent models, the Deviation Analysis tool identifies installation deviations by trade and floor, tracks quality trends, and proactively prevents downstream system clashes that could result in costly rework and schedule delays.
Key benefits of Deviation Analysis
Deviation Analysis delivers unparalleled value to construction teams, addressing critical pain points in quality control, coordination, and documentation.
1. Automated Quality Control
Imagine validating your entire project against the 3D model using tape measures or other manual methods. Not only is doing it that way unrealistically time-consuming, but it’s also very error prone. Working from quality scan data created by experts, Deviation Analysis automates this process, digitally detecting and tracking construction deviations throughout the project. This ensures consistent quality performance across trades and floors, streamlining the QA/QC process.
2. Risk mitigation
Unidentified deviations can lead to unforeseen clashes between systems, which can jeopardize schedules and budgets. Hexagon Building Solutions’ Deviation Analysis proactively identifies downstream conflicts caused by deviations, minimizing rework and preventing potential delays. This capability is particularly valuable for projects requiring tight adherence to tolerance specifications.
3. As-built insight
Accurate as-built documentation is critical for owner handover and long-term facility operations that need to know exactly what’s been built, and where. Construction reality capture records, like the scan data used for Deviation Analysis, provide a record of field deviations, enabling updates to as-built models that reflect the final state of construction. This ensures owners receive reliable documentation for maintenance and future upgrades.
4. Enhanced collaboration
Hexagon’s cloud-based solution seamlessly integrates with third-party issue management systems, supporting collaborative issue resolution among project stakeholders. Trade performance dashboards and configurable reports provide visual insights into deviations and clashes, empowering teams to make informed decisions quickly.
Why Hexagon stands out
While some competitors rely on manual processes or photogrammetry to assess deviations, Deviation Analysis leverages cutting-edge 3D laser scanning for unmatched precision. Photogrammetry can be useful for tracking construction progress, but it lacks the accuracy needed for meaningful deviation analysis. Hexagon’s proprietary scanning and analysis technology not only reduces turnaround time but also increases transparency in installation quality, offloading this critical task from project teams.
Here’s an example: Since 1898, AECOM Tishman has built over 600 million square feet, much of that on large and complex mega-projects. The Manhattan West mega project included seven mechanical floors and spanned 236,966 sq ft.
On projects of this size, AECOM Tishman Project Director Moheb Beshara says that clashes on the jobsite become costly rework, so the aim is to proactively find and address deviations between field installations and the Building Information Model (BIM).
Reality Capture was conducted weekly, and the laser scan data was compared to the BIM to identify discrepancies between design intent and reality. Hexagon’s Deviation Analysis solution identified 112 critical clashes within 12 months. Project teams were able to flag issues and quickly adjust their work in the field.
Project Manager Christian Peña summed it up nicely: “Hexagon Building Solutions lives up to its mission of being a system of records for buildings. Their technology makes our job easier. We can focus on solving issues, not finding them.”
Who benefits from Deviation Analysis?
The Deviation Analysis solution is ideal for complex projects requiring tight tolerances and multidisciplinary coordination. Stakeholders who can benefit include:
