Abstract :
The author describes the development of different estimates of the programmable control (PLC) system used for the Stelco Inc., Hilton Works continuous casters. He discusses: main costs to look for; accumulation of data to prepare an appropriation estimate; bidding process; check estimate to follow any changes, enhancements, and installation factors; fair cost estimates to cover field changes; and final percentage analysis. It is concluded that enhancements to PLC systems are very costly and should be looked at in the earlier stages of the project. Drive and digital control systems are an essential part of the PLC system, and, while evaluating the cost of PLCs, emphasis should also be placed on their costs
