In early $($pre$-$contract$)$ discussions, your design$-$&$-$build organisation sought informal prices from various sub$-$contractors for job packages $($eg steelwork, foundations, electrical services$),$ and used the lowest examples t o quote$-$for and win the job to design$-$&$-$build the retail$-$ company's office project. After winning the project, your company then sent revised, detailed design packages with changed scopes ot al local specialist sub$-$contractors, asking that they lower the early informal prices gathered. With reference to the code of ethics and case$-$study known to you, discuss how to address an ethical dilemma ni requesting subcontractors to re$-$ price more cheaply a modified changed scope, given that many have already spent time pricing previous packages for you, and assess acceptability ot give alternate subcontractors another subcontractor's cost to ask fi they can beat that price to win the re$-$designed package?
