Caddell has been recognized by Engineering News Record as among the nation’s “greenest” contractors based on volume of LEED projects and our consistent sustainable construction practices and principles. Caddell was practicing sustainable design and construction long before it gained industry prominence. Recycling paper and valuable metals; using demolished materials on-site for fill and stabilization; mulching waste from site clearing and grubbing for project landscaping, these have been standard Caddell practices for more than 34 years.
Caddell has likewise become a leader among LEED contractors with numerous LEED Gold and Silver certified projects including initiatives that represented important environmental milestones in their building sectors. Caddell’s design/build of the U.S. Embassy in Panama was the first standard embassy design to achieve LEED certification. Since then, two Caddell U.S. Embassy projects (Burundi and the Dominican Republic) have been certified as LEED Gold. The recently completed $193M Federal Correctional Institution in Aliceville, Alabama, is the first Federal Bureau of Prisons FCI to be certified as LEED Silver by the U.S. Green Building Council. Other Caddell projects have been similar LEED pioneers. Almost every Caddell project of the last five years has required LEED certification, most to at least LEED Silver criteria.
Important environmental projects in Caddell's project portfolio include the massive Solar Electric Generating Systems (SEGs) photovoltaic array in the Mojave Desert. This is one of the largest solar energy sites in the world and is currently producing over 350 MWs of electric power distributed to 200,000+ homes.
A major contribution to environmental science has been Caddell’s construction and subsequent 15-year maintenance and upgrades services to the Power Systems Development Facility (PSDF) at Wilsonville, Alabama. This impressive R&D complex is operated by the U.S. Department of Energy and the Southern Company with a goal of exploring new coal gasification technologies designed to increase the efficiency, cleanliness, and economic viability of coal-based power generation.
Recently, a new facility was added to the PSDF complex, the National Carbon Capture Center (NCCC) to study carbon dioxide (CO2) capture from coal-derived syngas and flue gas. The NCCC is the focal point for national efforts to reduce greenhouse gas emissions through technological innovation, and serves as a neutral test center for emerging carbon capture technologies.
