A small city has been notified by the State's environmental agency that its water system is not compliant with drinking water standards and the city must resolve its non-compliant issues. The city decides to hire an engineering firm for assistance and, subsequently, advertises a Request for Qualifications (RFQ) for engineering firms to respond. Services required include Preliminary Engineering to evaluate alternatives for solution of the non-compliance, and Design and Construction Engineering for the selected alternative. The RFQ requests specific information from the engineering firms that respond. Engineer A, in an effort to improve its chances of being selected by the city, offers to provide free Preliminary Engineering. The RFQ did not request any information regarding fees or engineering costs. Question(s): 1. Was the offer by Engineer A for free Preliminary Engineering ethical? NB: write your answer on the basis of the NSPE code of ethics and mention which all rules, fundamental, and professional obligations are related to this problem and explain in your words
