植物文档中的甜蜜成功

With the capacity to slice 22,000 tons of beets a day and produce over 1 billion pounds of sugar annually, the Michigan Sugar Co. is the third largest sugar producer in the United States. Its factories, which were built between 1889 and 1902, dot the Michigan landscape, providing employment to many people. During peak processing season, more than 1,000 grower-owners and 1,600 workers support the company.

Over the decades, Michigan Sugar has installed an assortment of machinery updates and additions in its Croswell, Michigan, USA plant. The company has also augmented operations with auxiliary buildings that house new machinery. Each time project managers have carved out space for the equipment and related piping, the plant has become more congested and complex. Until recently, as is typical in many factories, plant documentation had not kept pace with the ever changing environment.

Planning for a tank replacement

When Michigan Sugar Co.’s management decided to replace an evaporation tank that spans three stories inside the factory, the project engineer, Chris Schanbeck, knew careful planning was in order. In the past, to design the new structure and guide a project plan, his team might have updated old drawings of the facility with hand measurements of the planned installations. He knew, however, that inaccuracies and omissions in the as-built data could lead to unexpected equipment clashes and misfitting parts. The result would likely be field rework, increased costs and project delays.

为了确保合理的设计，Schanbeck需要一个全面，准确的，最新的，最新的工厂内部模型，该模型将为新储罐及其结构钢的支撑提供制造系统和组件的指导。全面的模型还将使团队能够计划如何移动安装新储罐所需的支撑设备，例如泵和管道。它将允许设计师建模如何在安装新储罐后最好地重新布鲁特和连接管道迷宫。

When Schanbeck researched his options for creating such a model, a colleague referred him to 3D Imaging Services in Flint, Michigan, USA. The company provides technology solutions that include 3D laser scanning and as-built modelling. Schanbeck believed the firm’s 3D laser scanning capabilities would allow Michigan Sugar to produce the most precise, detailed model possible. Michael James, project manager at 3D Imaging Services, headed up the project. “The project was already in the planning phase and Michigan Sugar needed a way to capture existing conditions rapidly, so time was of the essence. Because of this, we chose the Leica ScanStation P40 to document the plant. It enabled us to reduce both field time and processing time,” he says.
