| summary |
This article introduces a novel monitoring method for the construction of high-precision prefabricated structures based on multiple sensors and measurement technologies. The proposed method introduces the optical motion capture system and combines it with traditional construction measurement technology to achieve real-time dynamic monitoring of more than hundreds of points within a large construction area more than 18*10m. Tolerance fitting algorithms and the correction methods are developed and testified to provide a global tolerance with ±1mm. Meanwhile a real-time visualization interface is developed to provide the feedback and analysis of the tolerance for each structure components. As demonstrator, such monitoring system is applied in the real construction of a DfD (Design for Disassembly)-based prefabricated steel structure in the "Water Cube‚ (Chinese National Aquatics Centre) in Beijing. With the demand to control the flatness tolerance within 6mm (within a 25*50m area), a large area monitoring system was applied in the project and finally reduced the construction time within 20 days. |
