VMI Store 1. Log in 2. Read the barcode 3. Confirm your purchase 4. Log out VMI stands for Vendor-Managed Inventory -Small items can be purchased easily at site which saves production time. - Projects are invoiced monthly based on the consumption. - Consumption control is based on read barcodes and minimum quantities set for each - Supplier refills shelves when minimum quantities are reached. 14 22.1.2013 Ilkka Romo
Just in Time deliveries through terminal in framework phase Materials that will be lifted to the stories in structural phase are delivered through logistics terminal where storey specific materials are combined into truckloads and delivered to site in accurate time. Materials are lifted directly from the truck to the storeys. 15 22.1.2013 Ilkka Romo
