Reality Capture for BIM

Author:Renata Barradas Gutiérrez

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使用Leica Geosystems的激光扫描解决方案来创建BIM模型，该模型将指导Mera在西班牙Ourense省的电气变电站的重塑和扩展。该项目是一项雄心勃勃的倡议的一部分，该计划将部分吸收energy production generated by 17 new wind farms计划在该地区。

激光扫描 - 完整模型的基础

为了计划变电站的重塑和膨胀，第一步是以毫米的精度测量其距离，角度和区域。Sertogal SL用Leica ScanStation C10捕获了变电站，并通过Leica Viva GNSS技术获得了点云。

“我们已经工作了很长一段时间内广泛of Leica Geosystems equipment due to its great可靠性和精度。TheC10扫描仪也不例外 - 可以容易适应to scan buildings, substations or electrical high-tension towers,”said Sergio Rodríguez, technical industrial engineer at Sertogal SL。“激光扫描仪使我们能够捕获变电站，而无需进入有风险的危险高压区域。”

“The great precision andlack of noise在生成的点云中，我们可以在具有金属元素和网格的复杂结构中工作，以获取成为现实的真实表示的BIM模型，”said Rodríguez.

点云的后期处理，建模和管理狮子旋风, the market leader point cloud processing software. The rich as-built point cloud data from the substation was imported to Autodesk Revit to create the BIM model, and Autodesk Navisworks was used to insert and catalogue the elements into the BIM model.

每个人的智能资产文档

The 3D intelligent as-built model Sertogal SL obtained from the point cloud of the substation:

• 收集了现有条件
• 测量距离
• 分析了该网站

这为变电站和周围环境创建了初步计划。

“获得的大量数据使得元素和结构的非常准确的建模是变电站的一部分，”said Bruno Sánchez Ucha, BIM expert at Sertogal SL.

交付的变电站的BIM模型使利益相关者能够进行数字旅行，该旅行提供了捕获的现实的完整前景，并具有链接信息的不同部分和元素的可视化。

电线，试管，隔离器，断路器等被嵌入为智能元素，并将其分组为系统。这使参与重塑的所有各方都可以回顾预计的变电站开发的外观以及变化将如何改变当前空间。

这个基于智能模型的设计过程将有助于将来开始翻新和管理运营，并将以精确和更有生产力的方式驱动工作流程。

BIM – a must-have

An increasing number of companies around the world understand the value and benefits of BIM across the lifecycle of building and infrastructure projects.

对BIM项目的需求不断上升，这使Sertogal SL有机会将自己定位为西班牙先驱，为几个维护和翻新项目提供BIM服务。

Governments around the world, such as the Ministry of Public Works in Spain, are recommending, encouraging or mandating BIM, recognising the value and benefits it delivers:

• 减少项目持续时间和周期时间of specific workflows.
• Enhance collaboration and coordination在项目的每个阶段。
• 减少错误and omissions with accurate documentation.
• Create new business通过提供新服务。
• 增加利润，并降低建筑成本和浪费。

专业人士必须配备激光扫描仪，该激光扫描仪可提供出色的精度，速率，速度和数据质量以创建BIM模型。Leica Geosystems激光扫描技术有助于创建这样的模型，以提供正确的见解，以便管理人员可以理解风险并做出明智的决定，尽管时间限制了。
