Construction Process

In civil engineering, construction is the combination of art and science, to construct a physical and naturally built environment, starting from the design phase. The construction process falls under the area of building construction, which is a sub-branch of civil engineering. Hence, it is also sometimes called the design and build or design-build process. The work of construction is majorly carried out by civil engineers and design professionals along with a team of works consisting of contractors and subcontractors.
