when I first got my license, I got a large job with a fair amount of underground conduits. The super wanted me to get my conduits in before the rough grading was done. Being young and not too experienced I did it. In some cases my trench was 5' deep and when the rough grading was done my conduit was on the surface of the ground. Long story short, why does he think you should go to so much extra work to make his job easier? He needs to understand the order of things.
