He maintains consistent working relationships with a core group of experienced contractors, including ARELI, INC., THE ROBINS & MORTON GROUP, J & J MAINTENANCE INC, ROYCE CONSTRUCTION SERVICES, LLC, and VALIANT CONSTRUCTION LLC. These partnerships reflect a preference for established firms with proven capabilities in military construction, facility maintenance, and complex civil engineering tasks.
