Workflow
A structured, domain-specific workflow — from data ingestion to delivery.
Structural elements mapped to BIM object categories (columns, beams, slabs, walls, MEP). Progress status categories defined: not started, in progress, completed, deviation detected.
Drone orthomosaics, oblique views, 360° photos, and time-lapse video ingested with GPS coordinates and BIM reference points. Image quality checks for weather-related degradation.
Per-element progress status labeled by comparing drone imagery against BIM design models. Deviations (incorrect placement, dimension variance, missing elements) flagged with severity and measurement annotations.
Structural defects (cracks, spalling, corrosion, water damage) labeled with type, severity, and location. Safety compliance: PPE detection, barrier placement, restricted zone violations.
Architectural drawings and floor plans digitized into vectorized room boundaries, wall segments, door/window openings, and MEP routing. Room types classified for property analytics.
Labeled data delivered with BIM element ID linkage, GPS coordinates, and progress reports formatted for construction project management platforms (Procore, PlanGrid, Autodesk BIM 360).
Expertise
Generic annotation vendors can label data. Domain experts label it correctly. Here's why the difference matters in your industry.
Understanding whether a poured slab matches BIM specifications requires knowledge of construction tolerances, staging sequences, and material properties. Our annotators are trained on construction methodologies — not just visual pattern recognition.
Construction monitoring isn't a single snapshot — it's tracking change over weeks and months. Our temporal annotation pipeline maintains element-level progress histories, enabling percent-complete calculations and schedule deviation detection.
Detecting missing PPE or barrier violations in construction imagery can prevent serious injuries. Our safety annotation taxonomy covers 20+ violation types with severity classification — enabling real-time safety monitoring AI.

FAQs
Yes. We annotate construction progress by comparing drone imagery against BIM design models at the element level — identifying elements that are not started, in progress, completed, or deviating from the plan with dimensional measurements.
We cover structural cracks, spalling, corrosion, water damage, formwork defects, rebar exposure, and more. Each defect is classified by type, severity (1-5), and location with measurement annotations for engineering assessment.
Yes. We convert architectural drawings into vectorized formats with room boundaries, wall segments, door/window openings, MEP routing, and room type classification — ready for property analytics, space planning, and indoor navigation applications.
Our annotation pipeline scales across multiple sites with site-specific taxonomies, consistent labeling standards, and centralized QA. Each site's annotations are linked to GPS coordinates and BIM element IDs for project management integration.
