Build on data, not on assumptions
Drawings that don’t match cost you time, money and margin. We deliver the digital basis you use to calculate, coordinate and hand over accurately.

A reliable digital basis from day one
You know how it goes. The construction drawings are from 2003, there have been three refurbishments since and nobody kept track. Your estimator calculates on the basis of what’s there, your work planner plans on the basis of assumptions and the subcontractor discovers on site that the situation is different from what was expected.
The result: delay, discussion with the client and an additional works claim you’d rather have avoided.
CREW-B takes that uncertainty away. We scan the existing situation to centimetre accuracy, process the data into a usable BIM model and unlock everything digitally. That way, everyone in your chain works with the same reliable information from day one.

Digital certainty from calculation to handover
3D Laser scanning on site. Our NavVis VLX mobile scanner maps the entire building. From basement to roof, from load-bearing structure to pipework. An average building is scanned in a few hours, during working hours, after closing time or at weekends. Without work having to be stopped, without disruption to users.
Scan to BIM for work preparation and calculation. We process the point cloud into a structured BIM model to BIM basis ILS. Architectural, structural and, on request, also installation. In Revit, IFC, AutoCAD. Your estimator pulls quantities out of it. Your work planner plans on it. Your subcontractor knows exactly what to expect. No interpretation differences, no surprises at the strip-out stage.
Indoorviewer for coordination and alignment. Via our web-based Indoorviewer, everyone walks through the building digitally. Your site manager checks a connection, the installer looks at the pipework route and the client views the location, without anyone having to be there. Measure distances, mark points and share them straight away. Works in every browser, without installation.
Model management via Docs. All models, drawings and project documentation in one place in Autodesk Docs. Your project team, subcontractors and client work from the same current set. No emails with attachments, no outdated PDFs on a site-cabin laptop.
As-built documentation at handover. After completion, we scan the end result and record the as-built situation. You don’t just hand your client a finished project, but also complete digital documentation ready for management, follow-on phases or future refurbishments. Increasingly often a requirement in tenders.
What we see in practice at contractors
“The drawings didn’t match” You start a refurbishment on the basis of existing floor plans. During strip-out it turns out that columns have shifted 20 centimetres, a load-bearing wall isn’t on the drawing or the pipework routes run differently than expected. The schedule slips, the estimator has to revise and the client asks why it’s getting more expensive. With a scan up front, you would have known this before the first quote.
“The subcontractor had different information” Your installer works from version 3 of the drawing, the structural engineer from version 5. On the building site, pipework and steelwork are in each other’s way. Clash detection on the basis of a BIM model flags this kind of conflict weeks earlier at the desk instead of on the scaffold.
“We had to go back to measure again” Your work planner is missing a dimension for the roof edge. Your estimator wants to check the shopfront opening. The site manager needs a photo of the meter room for the installer. Three site visits for three separate questions. With the Indoorviewer you answer all three in five minutes, from anywhere.
“The client disputes the existing situation” After handover, discussion arises about what has and hasn’t been changed. A scan before start and a scan at handover document both situations objectively. No he-said-she-said, but measurable data.
“We didn’t win the tender on price, but on approach” More and more clients don’t just select on price, but on way of working. A contractor that works with scanned data, BIM models and digital handovers shows professionalism and reduces risk for the client. It’s a differentiator in your quote.
Why contractors choose CREW-B
Fewer failure costs, better margin. Failure costs in construction average between 10 and 15% of the contract sum. A substantial part comes from working on the basis of inaccurate or outdated information. A scan up front is a fraction of those costs.
Immediately usable in your workflow. We don’t deliver data you first have to translate. The BIM model is ready for quantity take-offs, execution drawings and coordination. The Indoorviewer is immediately usable without training or software.
One source of truth for the whole chain: client, architect, work planner, site manager and subcontractors all work from the same data. That prevents noise, speeds up decision-making and reduces discussion on the building site.
No disruption on site. Our mobile scanner works fast and quietly. Scanning can run in parallel with ongoing works, even in occupied or operational buildings.
Complete in-house. From scanning to modelling and handover: we take care of the entire journey. You have one point of contact and one schedule, from first scan to final model.
In four steps to a reliable digital basis
1. Intake and scoping. We discuss your project: what is the current situation, which disciplines are relevant and what level of detail does your estimator or work planner need? For rollout projects, we first set the standard in a pilot.
2. On-site scanning. Our specialist scans the building with the NavVis VLX. Fast, unobtrusive and without impact on ongoing works or users. An average building is fully mapped in a few hours.
3. Processing and modelling. The point cloud is processed and converted into a BIM model to BIM basis ILS. Architectural, structural and, on request, also installation. Delivery in your preferred format: Revit, IFC, DWG or PDF.
4. Handover and access. The model and the scan data are made available via Autodesk Docs and/or the Indoorviewer. Your team and subcontractors have immediate access without extra software, without licences.
Projects for contractors and construction partners
Monkey Town Mülheim, Germany. The first international location for Monkey Town. We scanned the building and processed the point cloud into an accurate BIM model. The German architect used this as the basis for design and permit application. Via the Indoorviewer, contractor and architect could survey the building remotely without extra site visits.
Basic-Fit, rollout scanning and modelling. All digital twins of Basic-Fit clubs are available 24/7 in Docs. At every new location or refurbishment, the scan forms the basis for design, execution and management. The contractor on site works from the same data as head office.
Élysée Pavilion Paris. Scanned and modelled in collaboration with Hypsos for a temporary refit in the run-up to the Olympic Games. All elements including ornamentation and ceiling finishes were captured accurately as the basis for the contractor’s drawings.
Stadion Galgenwaard Utrecht. Complex scan of a stadium structure including GPS link to RD coordinates. The model served as the basis for technical adjustments and was used by several parties for coordination.
Our NavVis VLX delivers centimetre-accurate data. Depending on the application, calculation, work preparation or clash detection, we discuss the required accuracy level in advance.
Yes. Some contractors process the scan data themselves, or have it modelled by their own work planner. In that case, we deliver just the point cloud, if you want combined with the Indoorviewer.
Revit, IFC, AutoCAD or PDF depending on the systems you and your chain partners work with.
Yes. The NavVis VLX is mobile and quiet. Scanning can run in parallel with ongoing works, outside working hours or at weekends. Moving elements such as people are filtered out automatically.
Certainly. Via the Indoorviewer or Autodesk Docs, you give targeted access to subcontractors, suppliers or other project partners without software installation.
More and more clients value a data-driven way of working in the assessment criteria. A scan and BIM model as part of your approach shows professionalism and reduces project risk for the client.
