IFC Viewer vs GIStance

IFC Viewer helps architects, engineers, contractors and BIM coordinators open, inspect and check IFC2x3 and IFC4 models on iPhone, iPad and Mac. Go beyond 3D viewing. Review clashes and clearances, measure quantities, compare revisions, validate model information and create structured evidence for project reviews — all from one IFC workspace. VIEW YOUR IFC MODELS • Open IFC2x3 and IFC4 files in an interactive 3D viewer. • Explore buildings, storeys, elements, properties and quantities. • Search, select, isolate and inspect IFC objects. • Use Quick View for a fast check, or organise models and revisions into projects. • Review models at your desk, in meetings or on site. GO FURTHER WITH 14 OPTIONAL PRO TOOLS • Clash Detection — hard clashes, minimum distances and clearance checks. • Quantity Takeoff — geometry measurements, counts and takeoff baskets. • Model Compare — changes between baseline and revised IFC models. • Federator — bring multiple IFC models into one review. • IDS Validator + IDS Creator — check or author information requirements. • QA Reporter + Model Health — identify data-quality risks and model health issues. • Coordinate Checker — inspect origins, units, placements and coordinate indicators. • BCF Issue Tracker — capture, organise and export model issues. • COBie Reporter + COBie Updater — review COBie quality and supported data changes. • Parameter Dictionary, Query Studio and AI Data Compliance — explore IFC data and assess model evidence. NEW: PROJECT AUDIT & EVIDENCE PACK Choose a Model Health baseline review, or run Model Health, IDS Validation and Coordinate Checker together. Examine findings, statuses and evaluation coverage, revisit saved audit history and export an evidence pack containing PDF, CSV and JSON reports with a SHA-256 manifest. IFC and IDS fingerprints identify the source data used. Where information is missing, the app reports limitations instead of inventing a pass. Project Audit is included with verified Unlock All ownership or ownership of all 14 original individual Pro Tools. BUY ONLY WHAT YOU NEED The paid app includes core IFC viewing. Add individual Pro Tools as one-time in-app purchases, or choose Unlock All for all 14 current Pro Tools. No subscription. BUILT FOR REAL PROJECT WORK A practical local-first IFC review workflow across iPhone, iPad and Mac. Optional online features may require internet access. IFC Viewer supports review and analysis; its findings are not a substitute for project-specific verification or regulatory certification. Support and guides: ifcviewer.co.uk/support

GIStance turns an iPhone plus a connected GNSS receiver into a survey-grade field capture system for infrastructure, utility and construction crews. Centimeter-level positioning, georeferenced photo documentation, and 3D LiDAR scanning — captured on site, structured for the office. Built for FTTX rollout, utility networks and construction documentation, GIStance replaces the paper-notes-plus-consumer-camera workflow with a single tool that records where every asset is, what it looked like, and when it was captured. Precise positioning • Connect an external GNSS/RTK receiver for centimeter-level accuracy • Live fix status and accuracy readout before you record a point • Positions attached to every photo, measurement and scan Georeferenced photo documentation • Capture site photos with coordinates, timestamp and accuracy embedded • Tie documentation to project sections and construction phases • Consistent, auditable evidence for as-built records and billing 3D LiDAR scanning • Capture point clouds and meshes of trenches, structures and installations • Scans stored as measurement artifacts alongside points and photos Built for the field • Works with mapped basemaps for on-site orientation • Fast capture flow designed for gloved hands and daylight screens • Data queued and synced when connectivity allows Part of a documentation ecosystem Field captures sync to the FotoGIS asset hub and become available in the GISdoc office platform for project tracking, phase completion, plan-vs-actual comparison and report generation. What the crew captures on site is what the office works with — no manual re-entry. Who it's for • Field surveyors and rollout crews • Utility and network operators • Construction documentation and as-built teams Requirements GIStance requires a compatible external GNSS receiver for survey-grade accuracy and an active GISdoc/FotoGIS account. It is a professional B2B field tool, not a standalone consumer app.
