For building projects 35 % and for infrastructure projects almost 80 % of the project cost goes to structural work. Structural cost optimization through value engineering helps to bring down the project cost to a great extent. In this context, value engineering is an integral part of structural designing and focus is always on to design a safe and yet economical structure.
