Technical Papers and Publications

Varying blast parameters for close in blasting on sensitive structures, NAT Conference (June, 2012) (with Lawrence Weller, Mark Rhodes) including a study on the impacts to historic structures in Manhattan NY.


Mark has demonstrated a high degree of technical expertise related to all facets of underground construction and is especially knowledgeable concerning drill and shoot operations… Mark provided a valuable link between the engineering staff and the inspection staff with his wealth of practical experience… He consistently demonstrated excellent leadership and management skills during his period on the East Side Access. He was responsible for managing a team of over 40 inspectors. I would not hesitate to recommend Mark for a senior position IN ANY Construction Management/Resident Inspection organization…”

Andy Thompson V.P. Hatch Mott Macdonald

I have found Mark to be of very high character and integrity as evidenced by his enthusiastic work ethic and positive attitude toward construction safety. He is highly knowledgeable and competent with OSHA (29 CFR 1926) and BATF (27 CFR Part 555) regulations. Mr. Rhodes is a credit to the underground construction industry and I look forward to working with him on a future project
