Bringing safety, productivity with laser scanning

炼油厂，冶炼厂和其他植物环境是非常复杂的结构，可以提出重大危害。高度复杂的植物和商店的任何建设和重建都需要根据实际网站数据的详细工程，以及严格的建筑和安装活动的维度监测。

In most rebuilding projects, new structures and utilities to be installed are connected to the existing infrastructure, so high tie-in precision is necessary. It is quite common in the industy that the as-built drawings are not available, or the construction and installation works do not meet quality standards. There is a great need to collect actual field data on the existing structures and utilities.

IBCON是全新和重建项目的调查，设计和建设的高质量输入数据提供商，已经参与了过去11年的大型工业项目，提供IT支持。如今，IBCON专注于使用Leica Geosystems技术和Aveva软件的炼油厂和冶炼厂。

恢复对建筑的信任

One of IBCON projects efficiently using these technologies is the IT support for a smelter construction, the Kola Peninsula. As the customer worked on the project, it faced certain negative factors that prevented it from meeting the deadline, and led to financial losses. To rectify the situation, the contractor hired IBCON construction and rebuilding IT support services, enabling project completion in due time.

The job was to reconstruct the geometry and position of the existing structures to be built/rebuilt as fast as possible. The total area amounted to95,200 sq m。我们的数据re presented as a number of reports for the customer. The reports indicated any deviations betweenas-designed and as-builtgeometry and position of the structures. These reports have helped the customer to make smart project decisions.

The project faced many challenges, such as:

• Huge scope
• Tight schedule
• Harsh working conditions on the operating facility (vibrations, steam, dust, hazardous releases)
• 许多运行车辆和网站上的操作设备（焊接机，起重机，卡车等）

在这种情况下，传统的土地测量是极其困难的，并且在某些情况下是不可能的。不需要损害调查准确性和高分辨率的快速，高效的过程。

Delivering results with laser scanning

The IBCON team used a Leica ScanStation laser scanner. Laser scanning technology最大限度地减少测量时间即使对于数千平方米的网站，也可以在保持高精度和分辨率的同时，即使是千平方米和难以进入的区域。

Laser scanning technology does not require an exact scanner orientation as is the case with the conventional surveying. It enables scanning in restricted view conditions and收购更多信息关于任何隐藏的结构。只有三家公司专家开展IBCON中的现场和内部激光扫描项目，很大程度上节省了努力。

Leica Cyclone softwareis used for primary laser scanning data processing. After that, they are aligned to the facility’s coordinate system. Laser scans are stitched by marker or point cloud matching.

平均测量误差是每100个扫描仪位置的≈7mm。随后，扫描点云导出到构建3D模型的Aveva E3D。每个物体（钢筋混凝土结构，钢厂，设备等）在云点内识别，以构建3D模型的几何形状。从AS-Design和AS-Build文档，唯一索引和层次结构级别拍摄的属性被分配给模型中的每个3D对象。

由此产生的扩展3D模型是用于根据客户要求生成报告的工具。从激光扫描数据构建的3D模型与项目开发人员提供的3D模型匹配。以这种方式，在报告中容易识别并列出所安装结构与预期位置的任何偏差。

In the context of today’s extensive construction environment and its demand for prompt and mass-scale data acquisition about each structure built on a site, laser scanning technology provides complete visibility of any construction object. Such projects cannot be implemented with conventional land surveying tools as the data acquisition rate is very low.

“Surveying with the Leica ScanStation P20 laser scanner makes site surveys easy and visualises complex structures in a simple way,”米特拉夫说。

在项目完成之前，上述服务作为循环执行，并进行调试。IBCON的施工和重建项目IT支持服务帮助客户在每个阶段提示决策，使用准确和及时的报告监控项目完成，并降低额外的错误整流成本。
