He has been appointed as the department manager for an upcoming large chemical process plant that will be designed and constructed by the organization that he is currently attached to. Baha's responsibilities will include organizing the process unit staff and overseeing the project designers' sketch plans to ensure that the new plant will be designed safely, operable and maintainable. After the construction, he will then be responsible to start up the plant. From experience, Baha noted that a new type of valve sold by a newer supplier could be used in place of more common gate valves sold by established suppliers.
