I would first check with others who are in a similar role as yours within your company and see what advise or guidance they can give you as they likely had the same issues when they first started there new roles. You can go to your human resource dept. and seek guidance from them."
This is excellent advise and about word for word what I was going to say, so no need to say it twice. Good luck, and remember that no matter how easy it might be for you to complete a task in the field, that it is a job for the guys being paid to do that job. Your job is to make sure they get 'er done safely, on budget and on time. I've been where you are before. It isn't easy to go from the field to behind a desk. But with a little finesse, it can be done.
