Within that range bring skilled project managers with the ability to develop technically sound work plans and cost estimates, respond to regulator comments, and assist with community regulations.

In addition, we also maintain a radioactive materials license which permits us to handle all quantities and forms of radioactivity throughout the country (via interstate reciprocity), and a License for Delivery for the disposition of radioactive and mixed waste.
