IITU Multi-Temporal Building Floor-Count Dataset: 12-Month Fixed-Viewpoint Construction Sequence

This dataset provides a controlled, multi-temporal collection of street-level video recordings of a single reinforced-concrete building under active construction, captured from a fixed-viewpoint camera at the International Information Technology University (IITU) in Almaty, Kazakhstan. It was assembled to study the visual invariance of building floor-count estimation across construction stage, illumination, weather, and season, and accompanies the associated manuscript currently under peer review. The recordings span a twelve-month period, from May 2025 to April 2026. Because all footage depicts the same structure from the same vantage point, the building has a fixed ground-truth count of six structurally completed floors throughout the sequence; the collection is therefore intended as a robustness resource over environmental and construction-stage variation rather than as a source of floor-count class diversity. Between May and August 2025 the building was in a raw construction stage (exposed reinforced-concrete frame with no installed curtain-wall glazing or cladding); from September 2025 onward, progressive installation of glazing and exterior cladding transitioned it into a partial-finish stage. A completed stage is not represented, as facade installation had not finished by the end of the observation window. Capture protocol: Footage was recorded by a stationary street-level camera with a fixed field of view directed at the building facade. The recordings capture day-to-day and seasonal variation in illumination, weather, and construction progress over the full observation window.Intended use: This dataset supports research on construction-stage building monitoring, floor-count estimation from street-level imagery, and the robustness of visual models to seasonal, weather, and construction-stage appearance change. The annotated still-frame subset used in the associated manuscript will be added in a subsequent version of this dataset.
