Robert Maule, P.E.

Areas of Expertise

Robert Maule is a licensed Professional Engineer in New Hampshire and Maine with more than twenty-five years of engineering experience primarily in the area of power generation. At various times in his career he has had involvement in the inspection, operation, and maintenance of fossil fuel, hydro, combined cycle and nuclear power plants. He also served as a Field Service Engineer for a major boiler supplier and was responsible for the erecting and overhauling of power boilers.

Since joining Criterium-Brown Engineers in 2004, he has been involved with the inspection of houses and a retail facility in northern Maine.


After graduating from college Mr. Maule worked for five years as a marine engineer, a vocation that provided ample vacation time during which he taught himself how to design and build houses. During the construction of his first home the principles of plumb, square and level seemed quite elusive, however, he persevered and ultimately began to build houses, garages, decks and handicap ramps for customers. From there he started his self-education on residential plumbing, wiring, building thermal efficiency, and heating system design.

In his power generation profession, which he conducted alongside his building career, he found that many of his responsibilities at the plants complimented his construction work. He has been responsible for plant reliability improvement, procedure writing, operator training, equipment and facility inspection, and the supervision of construction projects at various client power generating stations.

Presently, he is employed as an engineering consultant for a large insurance company that provides coverage for many industrial and commercial locations. He is involved with risk assessment, loss prevention, claims investigation, and fire prevention at their insured locations.

Mr. Maule is a member of the American Society of Mechanical Engineers Power Division, Plant Operations Committee.
