Construction Engineering is an inter-related complex of operation whereby buildings and installations are erected. The end-product of construction is finished building for its functional use. Construction operations may be classified according to the methods and purposes such as erection of form work masonry construction etc. or by the type of material to be processed such as concreting, earth moving etc. According or specialised operation whereas excavation of earth by manual labour is a general type of construction work.
Construction process in character of performance may be mechanized or non-mechanized and in degree of complexity-simple and complicated. For example levelling using a bull dozer is a simple mechanized work whilst excavation by power shovel is mechanized complex work.
Construction is vital for national development. It may be defined as the creation, renovation, repair and demolition of immobile structures and the alteration of natural topography of the ground. Construction-both the activity and the resulting product are notably visible and tangible.
Construction reflects the economic, social and cultural activities and value of society. The buildings and engineering projects with which people come in daily contact affect, in some complex way, their moods and attitudes, their effectiveness and the quality of their lives. Conversely, the traditions, aspirations and vitality of people are reflected in their settlements and their constructed environments.
Most construction projects are complex, both technically and commercially. There is considerable specialization, both among types of construction and among onsite operations of a particular project. With the increasing, understanding of materials, improved design, improved construction and management techniques and introduction of computers, modern construction is a multi-disciplinary activity. Technological change in construction tends to be gradual and includes a wide variety of individual development in materials, equipments, and methods
