Contents Lean Construction Ireland Annual Book of Cases 2020 71 Case 17 This digital asset has enabled us to innovate the project delivery process. Greater levels of trade partner involvement, off-site manufacture (OSM), and modularisation are now possible. This results in less waste, as well as simpler, safer, and higher quality construction. Commissioning starts much earlier in the virtual space of the digital asset and enables commissioning to influence design and construction. This avoids the waste associated with being constrained by a late start and fixed finish. The ability to see the digital asset earlier has had a profound influence on quality and customer satisfaction. This front- end loading of design facilitates positive change at a point when the cost of change is minimal – a few keystrokes versus strip-out and re-fabricate. The DePD process exposed an opportunity to use the digital asset product created to support a number of Lean techniques for the construction group. Advanced Work Package Planning incorporating Takt Planning Methods This technique involved the assignment of appropriate construction areas to the project. These construction areas were further divided by trade partner scope. Once assigned, the areas are integrated with the construction schedule. Analysis of the schedule and scope allowed for an appropriate sequencing of work across the trades and areas to support the agreed schedule. The digital asset was used to support this technique. The intelligent 2D schematics of the digital asset is integrated with the 3D model of the digital asset. This allowed for the scope of construction area work to be identified early in the 2D phase so that the 3D model was developed in alignment with the work package sequences of the schedule. This in turn allowed the tagged item data of the construction areas to be delivered to the procurement system to support the required delivery of equipment on-site per work package area and as per the construction sequence. This phased delivery of information and physical equipment supported the progressing of construction areas by our trade partners in the agreed sequence. Paperless Receipt Verification Coupled with the above initiative was the opportunity to use the information to support a paperless receipt verification process. The delivery of equipment and information was forecasted and executed based on the agreed schedule from the advanced work package process. The as- specified information moved from the design section of the digital asset to the construction management section. The construction management system supported our Lean process via the use of mobile devices configured to present the as-specified information for equipment to the user as a digital check sheet. The mobile device allowed for electronic signatures and photographs to verify the completeness of the paperless verification activity. Early Computerised Maintenance Management System (CMMS) The DePD process allowed us to create datasets from the managed project data for loading into the client’s maintenance management systems. This preloading of data followed the system release schedule from the commissioning phase and hence allowed for maintenance activities to be appropriately set-up and ready for start-up. This initiative has reduced the duplication of effort associated with CMMS build activities and increased the quality of the information available.
