Lean Construction in action The use of 3D laser scanning enables rapid in-process verification at every stage of fabrication and construction, creating a closed control loop in which every participant can actively contribute to the success of the project. This is an important enabler of Lean Construction, which aims to eliminate wastage of any kind. Laser scan data can be imported into the 3D design environment and quickly compared with the design model for every item, even down to individual pipe spools. As IES has proved, this ability to continually check and resolve deviations almost in real time is just as valuable on brownfield projects as it is for new builds. By overlaying the scans onto the design model, IES can quickly generate accurate deviation reports, enabling the client to assess the nature and extent of any deviations and make informed decisions to reject or accept any non-compliant spools, vessels or structural components. These deviation reports are very important to IES's clients; the ability to identify incorrectly fabricated items to avoid on-site rework can save considerable costs. Randy described how IES had recently scanned six filter-vessel skids that had been fabricated in Canada and produced detailed deviation reports to the client's specification. Scanning in the fabrication shop creates a baseline for asset integrity. If any fabrications are damaged during transit, installation or start-up, more scans can be captured and overlaid on the originals to determine the extent of the damage. IES used this capability for a large process facility located in Bakersfield, California, for which the piping was fabricated on the east coast of the US. Laser scanning was used to verify the accuracy of the fabrications before their shipment across the US, saving IES's client over $2 million. continued... AVEVA World Magazine 2014 | Issue 2 p21
