Q5/ The structural engineering design section within the engineering department of a regional electrical utility corporation has developed several standard designs for a group of similar transmission line towers. The detailed design for each tower is based on one of the standard designs. A transmission line project involving 50 towers has been approved. The estimated number of engineering hours needed to accomplish the first detailed tower design is 126. Assuming a 95% learning curve, a. What is your estimate of the number of engineering hours needed to design the eighth tower and to design the last tower in the project? b. What is your estimate of the cumulative average hours required for the first five designs?

QUESTION 5 You are the engineer responsible for the design and installation of plumbing in a new public elementary school under construction. The project is running behind schedule ad above budget. The latest catch is that the supplier has not delivered the specified backflow preventers. Although a strike at the manufacturer's plant has been settled, the back order list is moving slowly. The engineer serving as coordinator of the project orders you to obtain less expensive backflow preventers that are readily available from another manufacturer. These backflow preventers are of lesser quality than those specified in the plans, have a history of occasional failure, and are likely to need earlier replacement. What should you do? O A. Order and install the available backflow preventers, but refuse to sign off on this portion of the job. O B. Order and install the available backflow preventers, informing the school board that this equipment may not last as long, but will help the project…
