BIMSmarter IFC Viewer's answer
BIMSmarter IFC Viewer's answer
BIMSmarter was founded by Renaud Climent, a working BIM coordinator in Luxembourg, out of a very concrete frustration: auditing an incoming IFC model took two to four hours of manual checks per deliverable, repeated on every project, and the same twenty checks were done by hand every time. The tools that automated it were expensive, installed, and required sending models to a cloud, which many clients refuse.
So the audit was rebuilt as a browser tool that runs entirely on the user's machine. IFC Viewer & Audit is one of four BIMSmarter tools, alongside an ISO 19650 document naming generator, a workflow and RACI generator, and an assistant for the Luxembourg CRTI-B GID requirements. All four are free, because the goal is that everyone on a project, including subcontractors, can meet the same standard.
BIMSmarter IFC Viewer's answer
BIM coordinators and BIM managers in architecture and engineering firms, design offices and contractors, mainly in Luxembourg, Belgium and the wider Benelux, working on ISO 19650 projects. Two moments matter to them: checking a model just before delivery, and checking a model just received from a subcontractor. Secondary audience: clients and project managers who need to verify the quality of a deliverable without owning a BIM licence, and students or small practices who cannot justify a per-seat checker.
BIMSmarter IFC Viewer's answer
Because the full audit workflow is free, needs no installation and no IT approval. Solibri and Revizto are powerful but licensed, installed and priced per seat. Trimble Connect and Autodesk BIM 360 are collaboration platforms: you have to upload your model to their cloud first. Free viewers like BIM Vision or usBIM.viewer+ require a Windows install and stop at inspection.
BIMSmarter IFC Viewer sits in the gap: open a browser tab, drop an IFC, get a compliance score, a BCF file and a PDF report. It is also built around European practice, with buildingSMART IDS, ISO 19650 and DIN 277 as first-class citizens rather than add-ons.
BIMSmarter IFC Viewer's answer
Two things. First, nothing is uploaded: the IFC file is parsed by WebAssembly inside your own browser, so a confidential model never leaves the workstation and no server ever holds it. Second, it does not stop at viewing. It authors and validates buildingSMART IDS 1.0 specifications, scores the model, exports non-conformities as BCF 2.1, produces a PDF audit report with a verifiable certificate, and computes quantity take-offs and a DIN 277 room schedule. Most free viewers show geometry. This one tells you whether the model will pass the client's check, in under five minutes, and hands you the evidence.
