Question 1

What equipment do you use for scanning?

Accepted Answer

We utilize industry-leading scanning equipment including NavVis VLX mobile mapping systems, GeoSLAM handheld scanners, and Leica RTC360 terrestrial laser scanners. Each tool is selected based on project requirements, from large-scale building documentation to detailed interior captures.

Question 2

How accurate are your 3D scans?

Accepted Answer

Our scanning delivers millimeter-level accuracy, typically ±2-5mm depending on the equipment and project requirements. This precision meets or exceeds industry standards for BIM modeling, construction documentation, and facility management applications.

Question 3

What is reality capture and how does it work?

Accepted Answer

Reality capture is the process of digitally documenting the physical world using 3D laser scanning technology. We use advanced equipment like NavVis VLX, GeoSLAM, and Leica RTC360 scanners to capture millions of precise measurements, creating detailed 3D point clouds that serve as the foundation for digital twins and BIM models.

Question 4

Can you scan occupied buildings?

Accepted Answer

Yes, we specialize in scanning occupied buildings with minimal disruption to operations. Our mobile scanning systems allow us to work around occupants and equipment, typically requiring access for just a few hours per area.

Question 5

What is the difference between LOD levels?

Accepted Answer

Level of Development (LOD) ranges from LOD 100 (conceptual) to LOD 400 (fabrication-ready). We typically deliver LOD 300+ models that include accurate geometry, materials, and spatial relationships suitable for construction coordination and facility management.

Question 6

What file formats do you deliver?

Accepted Answer

We deliver in industry-standard formats including Revit (.rvt), AutoCAD (.dwg), IFC, Point Cloud (.rcs/.rcp), and Navisworks (.nwc/.nwf). We can also provide specialized formats for specific software platforms based on your project requirements.

Question 7

What is EMD and why is it important?

Accepted Answer

Existing Model Detail (EMD) is a classification system for documenting existing building conditions using reality capture. EMD levels ensure consistent data quality and completeness for renovation projects, helping architects and engineers make informed design decisions.

Question 8

What is CERQA and how does it relate to BIMstream?

Accepted Answer

CERQA is BIMstream’s flagship software platform, an intelligent, secure environment designed to centralize, organize, and activate building data across an entire real estate portfolio. It serves as the operational command center for digital twins, allowing owners, operators, and project teams to host, view, share, and connect any building system, dataset, or analysis tool in one place. Developed and maintained by BIMstream, CERQA is the backbone of our digital twin ecosystem. While BIMstream provides the strategy, services, and expertise to capture and model your building data, CERQA is where that data comes to life powering visibility, collaboration, and smarter decision-making across the asset lifecycle. In short: BIMstream builds your digital twins. CERQA helps you use them to run a better, more informed portfolio.

Question 9

What is BIMstream FIELD and how does it relate to CERQA?

Accepted Answer

BIMstream FIELD is our mobile and desktop toolset designed to help teams capture site conditions quickly, consistently, and with complete accuracy. FIELD streamlines on-site walkthroughs, documentation, and QA/QC by enabling users to record issues, collect photos (including 360 imagery), validate construction progress, and sync information directly from the field. FIELD connects seamlessly with CERQA, BIMstream’s core digital twin platform. All data captured in FIELD photos, notes, markups, punch items, and verification records flows directly into CERQA, where it becomes part of the living digital twin. This ensures that project teams, facility managers, and owners always have real-time, trustworthy information to support decision-making. In short: FIELD captures what’s happening on site. CERQA organizes it, contextualizes it, and makes it actionable across your entire portfolio.

Question 10

Can I See a Demo of CERQA?

Accepted Answer

Yes! You can learn more and book a demo by visiting: app.cerqa.cloud

Question 11

How long does a typical scanning project take?

Accepted Answer

Scanning duration depends on project scope and complexity. A typical commercial building (50,000 sq ft) requires 1-3 days of on-site scanning, followed by 2-4 weeks for data processing and model development. We provide detailed timelines during project planning.

Question 12

What areas do you serve?

Accepted Answer

We provide scanning services across the globe, with extensive experience in major metropolitan areas. Our team has documented over 100 million square feet of building space for clients ranging from universities to healthcare systems to commercial real estate.

Question 13

How do you ensure data security and privacy?

Accepted Answer

We maintain strict data security protocols including encrypted file transfers, secure cloud storage, and confidentiality agreements. All client data is handled in compliance with industry standards and can be delivered through secure portals or client-specified methods.
