"JBCC is committed to investing in its people and developing leaders at every level of the company. We do not put a ceiling on the potential of our teammates. That means you can start at the bottom of the organization and go just as high as your ability will take you. From working in the field to working in the office, from support roles to leadership roles, its all there for the taking." John Burns Construction Company offers a wide range of services in four main areas: General Contracting, Underground Utility Construction, Telecommunications, and Traffic Signals & Lighting Construction. Our history is one of constantly meeting new challenges, both in the marketplace and in new technology. Originally a pioneer and leader in underground construction, we later added General Contracting. Expansion was a natural outgrowth for us, as we worked closely with our customers, saw needs, and looked for ways to provide them with solutions. In fact, problem-solving is and integral part of John Burns Construction Companys business. During our many years in the construction field, we have accumulated first-hand experience solving more complex situations than most companies would even attempt. Safety is the number one priority for John Burns Construction Company. Our firm employs full-time safety directors that monitor everything from "Tool Box" meetings to Safety Training. We have QAQC manuals for our company to ensure that work is performed to our rigid standards of project quality.
