For more than 20 years, CALTROP has helped to build infrastructure projects that get people where they are going by land, air or rail - bridges, highways, roads, airports and rail transit - by offering high quality services in program / project management, construction management, inspection, specialty inspection, risk management and public relations. Now, we are also helping people to communicate through our telecommunications division, which offers full design and construction services to the industry, and energize the world with our energy services division.
