Scan to BIM
Whether you’re refurbishing, retrofitting or managing complex estates, Scan to BIM provides an accurate digital model of what already exists – helping you make smarter decisions, faster.
At Reltic BIM, we transform laser scans into data-rich 3D models in Revit or IFC formats, tailored to your design, planning, or asset management needs.
Capture Reality. Model with Confidence.
Scan to BIM is the process of capturing a physical space using 3D laser scanning and converting it into a Building Information Model (BIM). It’s ideal for projects where:
- As-built drawings are missing or unreliable
- The site is complex, occupied, or hard to access
- You need exact geometry before design or retrofit
Our team uses industry-leading technology to deliver clean, accurate models ready for design, coordination, or planning approval.
Clarity Before You Build
Traditional surveys often fall short – especially on complex or older buildings. With Scan to BIM, you don’t just get floor plans or elevations. You get a detailed, data-rich model that reflects the true conditions on site.
This means fewer surprises, more accurate design work, and better decisions from day one.
With Scan to BIM, you can:
- Understand the existing building in 3D see the exact geometry of walls, floors, ceilings, roofs and structure - ideal for retrofit or extension planning.
- Spot risks before they cost you Identify irregularities, access constraints or clashes with proposed works early - reducing rework and budget blowouts.
- Design with real-world accuracy model directly from the point cloud, ensuring that new components and MEP layouts align precisely with what’s already there.
- Save time during preconstruction accelerate planning and reduce site visits by giving your design team reliable, measurable data from day one.
- Communicate more clearly with stakeholders use the 3D model to visualise constraints, access zones or phasing - helping clients and contractors make faster, smarter decisions.
From Point Cloud to Revit Model
From survey to model, we handle every stage of the Scan to BIM journey – ensuring you get reliable, accurate, and fully coordinated digital outputs.
Site Survey & Laser Scanning
We scan your site using 3D laser tools or photogrammetry to capture detailed spatial data of the existing structure and layout.
Point Cloud Registration & Cleaning
The raw scan data is carefully aligned, filtered, and cleaned to remove noise, ensuring a clear, accurate base for model creation.
BIM Modelling to LOD Standard
We create architectural, structural and MEP models based on your chosen LOD, suitable for design, planning, or coordination.
Model Delivery in Required Format
Your model is exported and shared in Revit, IFC, DWG or any format that fits your workflow and software environment.
Review & Quality Assurance
We walk through the model with your team to verify accuracy, usability and integration with your project requirements.

Not Just for Architects
Scan to BIM is increasingly used across all sectors of the built environment - not just in architecture. Whether you're dealing with tight urban sites, heritage assets, or complex MEP layouts, this technology helps reduce risk, improve decision-making, and support smoother delivery.
It’s not just a survey upgrade - it’s a smarter foundation for your whole project.
We’ve supported sensitive refurbishments of heritage and listed buildings where accuracy is critical. Scan to BIM allows you to capture fine details - such as mouldings, structural quirks, or irregular wall geometry - with millimetre precision, ensuring your design respects what’s already there.
Hospitals and labs are highly serviced environments where traditional surveys can miss key details. We help project teams model existing MEP, structural supports and ceiling voids, so you can plan upgrades or reconfigurations with complete clarity and minimal disruption.
For CAT A and CAT B refurbishments, having a true-to-life model of the internal layout helps avoid guesswork. You can measure ceiling heights, column spacing and service zones directly in the model, improving design accuracy and reducing programme delays.
From loft conversions to full block refurbishments, Scan to BIM helps developers and architects understand the starting point clearly. It’s ideal for projects where original plans are missing or out of date, and it helps avoid costly mistakes later.
We’ve delivered Scan to BIM models that map out installed mechanical and electrical systems - including pipes, ductwork, risers and plant. This enables better coordination with new works and drastically reduces design-stage clashes and rework on site.
Many education buildings have evolved over decades with little documentation. Our Scan to BIM service helps estates teams create digital records of space layouts, service zones and access routes - ideal for long-term maintenance, planning and funding.
Design with Certainty. Build with Confidence.
When you’re working with existing buildings, uncertainty creates risk. Inaccurate drawings, hidden services, and structural surprises all lead to delays and rising costs.
With Reltic BIM, you start with a clear, detailed model of what’s already on site – helping your team plan smarter and build with fewer surprises.
Benefits
With Reltic BIM, you can:
- Detect clashes early with structure and MEP
- Verify dimensions precisely before fabrication
- Reduce RFIs and costly site variations
- Improve coordination between all project partners
- Save time and money during the preconstruction phase
What That Means in Practice
The Scan to BIM Advantage on Site
- Get accurate data before design even begins
- Align design and site conditions from day one
- Coordinate trades with fewer conflicts and delays
- Increase trust between contractors and consultants
- Deliver projects with greater speed and confidence
Know What’s There. Manage It Better.
Scan to BIM isn’t just for architects and contractors – it’s an invaluable asset for facilities managers, estate teams, and building operators. Accurate digital models of your building allow you to see exactly what you’re managing – from spatial layouts to service routes and plant locations.
Whether you’re maintaining a single property or an entire portfolio, Reltic BIM helps you move from paper-based records to a structured, visual, and measurable asset database. It’s about making smarter decisions faster with a model you can trust.
With Reltic BIM, you can:
- Digitise your building assets
- Visualise layouts and services
- Plan maintenance with clarity
- Minimise downtime on site
- Enable smooth 6D handovers
- Improve asset data accuracy

FAQs – Scan to BIM Explained
Got questions about Scan to BIM? You’re not alone. Here are some quick answers to help you understand the process and its benefits.
What is a point cloud?
A point cloud is a digital 3D representation of a physical space, created by laser scanners. It consists of millions of individual data points that capture the geometry and dimensions of a building or site with high accuracy. This forms the basis for your BIM model.
What software do you use?
We use industry-leading hardware like Leica and Faro scanners to capture site data. Our team then models using Autodesk Revit as standard, but we can also deliver in IFC, DWG, or Navisworks formats to suit your preferred workflow.
What LOD levels do you offer?
We provide models ranging from LOD 100 (basic massing) to LOD 400 (detailed construction-ready models), depending on the stage and needs of your project. Whether you’re in early planning or preparing for installation, we’ll match the right LOD for your scope.
How accurate are the models?
Our models typically achieve accuracy within ±5mm, which is suitable for most design and coordination work. If your project requires tighter tolerances, we can adapt the scanning method and equipment accordingly.
Can you model MEP as well?
Yes, we offer full Scan to BIM modelling, including architectural, structural, and mechanical, electrical, and plumbing (MEP) systems. Just let us know the extent and level of detail you need, and we’ll include it in your quote.
How long does it take?
Turnaround times depend on the size, complexity and level of detail. On average, a Scan to BIM project takes 5 to 15 working days from site visit to model delivery. We’ll confirm your exact timeline after reviewing your project.
Do I need to clear the site?
Where possible, an empty or clear site improves scan accuracy and speed. However, we regularly scan active or occupied buildings – we’ll just need to plan around access and safety considerations in advance.
