At 40, I am sure you have 10 to 15 years experience. With that experience and PE, you should not have a problem making 90k and above easily as a civil engineer. With that money, if you are still not satisfied financially, I have no comments about it. About dis-satisfaction about the job, you have done it for so long and have gained much necessary skills and experience. I am sure you liked the profession since you have been in it for so long. About the management, you can definitely change to a new company. About IT, you will be starting at around 65k through consultancy with minimal training. Also, there is no guarantee you will like the new job or will be valuable in the field as you are now to the civil engineering world with that much experience.
