What is Civil Engineering?
Civil engineering is the design and maintenance of public works such as roads, bridges, water and energy systems as well as public facilities like ports, railways and airports. – American Society of Civil Engineers (ASCE)

Small Group Activity: • Bel Cheese recently opened a
manufacturing plant in Brookings, SD. Brainstorm the different types of civil engineers that were involved in the project before, during, and after construction.

Before
• Land Surveyor - Site topography• Geotechnical - Soil tests and foundation design• Structural - Building and internal structure
design. • Environmental - Water and wastewater system
design• Transportation – Mobilization of materials,
parking lot design

During
• Geotechnical - Consultation
• Structural - Consultation
• Environmental - Consultation
• Transportation - Moving construction materials to the site
