Consider a Bridge crossing 4,719 feet where the weight function is given by W = 3.2S + 30.5, the span cost amount is 2.8 $/pound and the pier placement cost is 14,979 Dollars per pier or abutment. Find the the practical optimum span length in feet. Hint, round to nearest number of integer pier spaces.

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.
