The Department of Civil, Construction, and Environmental Engineering seeks to apply knowledge of the laws, forces, and materials of nature to the construction, planning, design, and maintenance of public and private facilities. The Civil Engineering option focuses on transportation systems, bridges, roads, water systems and dams, pollution control, etc. The Construction Engineering option focuses on construction project engineering, design, management, etc.
History
The Department of Civil Engineering was founded in 1889. In 1987 it changed its name to the Department of Civil and Construction Engineering. In 2003 it changed its name to the Department of Civil, Construction and Environmental Engineering.

Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.
History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract
The endemic (e.g., PRRSV) and currently circulating FDAs such as African swine fever (ASF) strains in Europe and Asia cause severe mortality (98%) in affected farms. There is no commercially available vaccine for ASF or treatment. Therefore, viable options are limited and favor implementing a "stamping out" policy where entire herds containing infected animals are depopulated. Implementing rapid and humane disposal procedures during a pandemic becomes a challenge. Thus, a rapid and humane depopulation system of on-farm swine is required. Carbon dioxide (CO2) is one of the euthanasia methods approved by the American Veterinary Medical Association (AVMA) for the humane depopulation of a large number of livestock. One practical recommendation made to the swine industry for humanely depopulating is to utilize enclosed dump-bed trucks or trailers as CO2 euthanasia chambers. This idea has been validated at North Carolina State University research team using relatively simple setups built from generally available hardware. However, the actual implementation of such prototypes is difficult in an emergency when there is no time to read a detailed recipe on how to euthanize pigs with relatively simple temporary tools even though there the scientific papers describe how to set up and use it on individual farms. Therefore, we proposed a design concept for a low-cost (less than $20K) mobile CO2 vaporizer system for rapid and humanely swine depopulation for a routine (single mobile unit) or a mass depopulation (fleet of mobile units) scenarios.
