Ordinarily there should be either an established plan of intensive training to develop professional engineering competence, or several years of prior professional engineering-type experience, e.g., in interdisciplinary positions. In addition to meeting the basic requirement above, to qualify for this position you must also meet the qualification requirements listed below: Specialized Experience: One year of specialized experience which includes study, layout, and design of Military Construction (MILCON) and other federal facilities projects, including at least one of the following: formulating and resolving design issues during construction; developing whole building energy models utilizing energy modeling software; and/or performing or overseeing the technical review of mechanical, plumbing, and fire protection design products. This definition of specialized experience is typical of work performed at the next lower grade/level position in the federal service (GS-11). Some federal jobs allow you to substitute your education for the required experience in order to qualify. For this job, you must meet the qualification requirement using experience alone--no substitution of education for experience is permitted.
