What do an engineer and an architect do?

Engineers apply the principles of science and mathematics to develop economical solutions to technical problems. Their work is the link between scientific discoveries and the commercial applications that meet societal and consumer needs. Many engineers develop new products.

Architects design structures such as office buildings, businesses, stadiums, schools, malls, and homes. They might also design outdoor spaces. An architect will collect all information for a project to include site selection, environmental impact, zoning laws, building codes, and access to buildings for the disabled. They visit site locations to visualize their projects and prepare scaled drawings to submit to a client or employer as a design. They also estimate build costs, materials needed, and the projected time-frame to complete a build.
