Buildings are built for people’s comfort, business and industry they must be well designed structurally and well-constructed to fit the projected drawings. Designers need to be intelligent in multidisciplinary subjects: structural analysis, reinforced concrete design, steel designs, project planning and construction technology etc.
Bridges are Potential infrastructures that can link two banks of river, channel to be close. No bridge everything on one bank is distant away from another bank. Bridges must be well designed to support traffic loads and well placed to assure flood evacuation. Many fields of civil engineering come together including hydrology, structural analysis, reinforced concrete designs, pre-stressed concrete designs, steel designs etc.
Main infrastructures that connect people around the country by networking country sides, suburbs, urban areas and capital. Roads are the demand of the nation for their will in developing economy and reducing poverty. Road designs need knowledge concerning traffic control, geometry, pavement design, soil stabilization etc.
Structures that retain water for irrigation and hydropower. Hydraulic structures concern some specialties like soil and rock mechanics, structural analysis, hydraulics, hydrology and others. Hydraulic structures are not only help developing country side life but also producing electricity for use in industry.
