Even when minimum information per marker is used, material take-off is a complicated process. Pipe contents, pipe diameters and number of markers needed must be determined for each line. However, most in-plant take-offs are not done at one time by the same individuals. So areas are often double counted, omitted or taken off inconsistently. If too few markers are counted, installation can’t be completed while manpower is available. Inflating marker quantities to ensure an adequate supply simply produces leftover markers and added costs.
Using P&ID’s and/or a physical walk-through of your plant’s piping systems, our take-off team develops a list of marker legends showing the size, style and quantity of markers needed, as well as the drawing numbers, location and cost for each marker. We then meet with you to show you accurate fixed costs for the job, as well as options available to meet your schedule and stay within your budget.
