CONFIRMATION OF ON-SITE MEASUREMENT DATA
It goes without saying that the as-built information recorded from you site surveys needs to be as accurate as possible. The greater the quality and accuracy the chances of errors and poor design decisions are reduced.
3D laser scanning has become the preferred process for many design teams to obtain site measurement data. A key process within BIM designs which can be applied at the beginning, during and at the end of a projects cycle.
Beginning - What is there?
Knowing the exact dimensions of an existing structure, site or object may be critical to your design. Designers along with their software will always prefer to work within the confines of straight lines and perfect angles however reality teaches us that this is not always the case.
Incorrect alignment of fixing bolts can result in delays on site during installation of steel work. A fast and accurate 3D laser survey can be aligned with the original model for visual conformation before attending site commencing installation of site
As-built survey confirms mechanical plant installation against 3D model.
During - Confirmation
During construction or fabrication a 3D laser scan can be applied for verification purposes. Calculate any variance between critical elements and the original model and prevent errors and additional reworks.
As-built - Documentation
There are many reasons why a design and or an installation may change at any stage of a project. It is therefore important to record these changes and present them at completion. A simple point cloud overlay shows how these variations can be clearly identified and allow the model to be amended with the minimum of inconvenience.
