Digital Terrain Model for Noise Barrier Planning

Archizem's engineering team produced a Digital Terrain Model (DTM) for an 8 km railway corridor with a 50-meter buffer, covering areas both inside and outside settlements. This model established a consistent geospatial baseline for the design of noise mitigation measures.

The DTM was generated from aerial survey point clouds, with a final accuracy of 10 cm relative to the source data, making it suitable for detailed engineering analysis.

The project featured the coordinated delivery of multiple outputs: the DTM, a BIM model of railway infrastructure, and an existing-conditions plan at a scale of 1:200. Selected structural breaklines from the DTM were shared to ensure all deliverables were precisely aligned geometrically and spatially.

This coordinated package of data provides reliable baseline information for optimizing noise barrier design and managing the reconstruction process.
