Hello everyone. I have been getting bogged down with some quotations I need to get out. My question is if anyone has a example or "rule of thumb" for estimating programming cost for a project? I am not talking about software cost, cables, hardware,start-up, documentation or anything else you could think of, just the estimate for a ladder type program.
Right now I go by "day rate" which I have set up in a spread sheet. I "guess" (based on past experiences) how many days, or fractions of, it would take to sit down and create program. It seems to me that maybe I could just have a budgetary price for each I/O.
Keep in mind that I have also in the quotation materials,skid wiring, panel shop assembly, documentation along with appropriate profit margin mark ups on the entire project. So the program cost is not the make or break item of the entire project.
I am just looking for something a little more specific to base quote on than the "I think it will take this long" method. Thanks in advance for any input.
