Mr. Jobert commissioned you to estimate the construction of a certain structure. As Engineers, our job includes giving detailed estimate inclusive of labor and materials. If approved, the contract for building the structure will be awarded to you.
However, Mr. Jobert already had a previous consultation with Prudencio, an independent foreman, who offered labor and services at a cheaper price.
How will you convince Mr. Jobert to engage in your services instead of Prudencio's?
