Facts: City passes an ordinance requiring a sprinkler system in residences with less than eight feet between them and makes the ordinance effective as to all construction which has not yet received an occupancy permit. This means that projects under construction must have a sprinkler system added. Engineer A, who happens to have both structural and fire protection credentials, is hired by Homeowner to design a retaining wall system to stabilize a rear yard. Homeowner allowed Engineer A to store equipment in the integral garage. Engineer A observes that the builder routed the piping for the retrofitted sprinkler system through the unheated garage, exposing the pipes to freezing temperatures. Question(s): What are Engineer A's obligations? 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
