Correct you are about 600 MCM. I'm not doing my own math here.
The laterals were not specified by the power co. The project engineer specified the laterals on plans. Later admitting that they resized the MDP during the design and forgot the increase the service laterals.
The engineers later asked for change order pricing to increase to 4 sets #500MCM. ( thats where I got the #500). Now the owner has said he will not approve any additional funds. So the engineer has stated my change order request will not be approved. I am concerned about my liabilty in this issue due to not meeting the NEC. This project has turned very bad due to some other issues with design oh which I am taking a beating due to the engineer's faults. I really do not want to butt heads with the engineer and harm a relationship for future projects, But I do not think I have a choice. Anyone else have any ideas ?
