At the project meetings, you will note that the design is still open to changes. With the design criteria and key single‐line diagram in hand, you will be discussing with your civil, process, and mechanical counterparts on what is possible and reasonable and what is not, and what will cost “an arm and a leg” and what may be a more reasonable option. The developer may suddenly decide to add another process line in the plant, which may stretch your “almost finished” power distribution system or completely change it. Remember, a plant change on paper is 10 times less costly than doing it during construction (Figure 1.2).
