亚博ag真人规律BIM的现实捕获

3D digital models with integrated functional characteristics has changed the way in which individuals, businesses and governments plan, design, construct and manage buildings and infrastructure. Building Information Modeling (BIM) has changed the way professionals in the architecture, engineering and construction industries improve coordination and reduce rework thanks to 3D intelligent models that are accurate, accessible and actionable.

Sertogal SL used Leica Geosystems’ laser scanning solutions to create a BIM model that will guide the remodeling and expansion of the electrical substation of Mera in the Spanish province of Ourense. This project is part of an ambitious initiative that will partly absorb theenergy production generated by 17 new wind farmsplanned in the region.

Laser scanning – the foundation for a full BIM model

To plan the remodeling and expansion of the substation, the first step was to measure its distances, angles and areas, with millimetric accuracy. Sertogal SL captured the substation with the Leica ScanStation C10 and georeferenced the point cloud obtained with the Leica Viva GNSS technology.

“We have worked for a long time with a wide range of Leica Geosystems equipment due to its greatreliability and precision。这C10 ScanStationwas no exception - it can beeasily adaptedto scan buildings, substations or electrical high-tension towers,”said Sergio Rodríguez, technical industrial engineer at Sertogal SL。“The laser scanner allowed us to capture the substation without entering in dangerous high voltage areas with risks.”

“The great precision and缺乏噪音in the generated point clouds permitted us to work in a complex structure with metallic elements and grids to obtain a BIM model that is a true representation of reality,”罗德里格斯说。

这post processing, modeling and managing of the point cloud was done withLeica Cyclone，市场领导者点云处理软件。从变电站中的丰富的积分云数据导入到Autodesk Revit以创建BIM模型，并且使用Autodesk NavisWorks将元素插入和分类为BIM模型。

Intelligent asset documentation for everyone

从变电站的点云中获得的3D智能AS构建的模型Sertogal SL：

• 收集了面临g conditions
• Measured the distances
• Analysed the site

This created the preliminary plans for the substation and the surrounding environment.

“The great volume of data obtained made possiblea very accurate modelling of the elements and structuresthat are part of the substation,”said Bruno Sánchez Ucha, BIM expert at Sertogal SL.

这delivered BIM model of the substation allows stakeholders to take a digital tour that offers a complete outlook of the captured reality plus the visualisation of its different parts and elements with linked information.

Wires, tubes, isolators, circuit breakers and so forth, were embedded as intelligent elements and grouped in systems. This enables all parties involved in the remodeling to review how the projected substation developments will look like and how changes will transform the current space.

This intelligent model-based design process will help to start the renovations and manage operations in the future, and willdrive workflows with accuracy and in a more productive way。

BIM – a must-have

全球越来越多的公司了解BIM在整个建筑和基础设施项目的生命周期中的价值和收益。

这rising demand for BIM projects has convinced Sertogal SL of the opportunity to position itself as a pioneer in Spain, offering BIM services for several maintenance and renovation projects.

世界各地的政府，例如西班牙公共工程部，都建议，鼓励或强制BIM，认可其所提供的价值和利益：

• Reduce project duration and cycle timeof specific workflows.
• Enhance collaboration and coordinationin every stage of a project.
• Reduce errors并具有准确的文档。
• Create new businessby offering new services.
• Increase profit, and reduce construction costs and waste.

Professionals have to be equipped with a laser scanner that delivers outstanding precision, rate, speed and data quality to create a BIM model. Leica Geosystems laser scanning technology helps create such a model that provides the right insights so managers can understand risks and make informed decisions to deliver projects responsibly despite time constrains.
