Design firm may be generalists with experience in all building types or healthcare specialists with additional niche experience in subspecialty areas such as emergency department, adult or neonatal intensive care, laboratory areas, radiology departments, dietary areas, children’s hospital, or others areas. In the past, it has been customary to choose 1 architectural firm to do an entire new multispecialty hospital, but it has become increasingly common for hospital executives to choose several different firms to collaborate on a hospital design because of their knowledge and experience in specific clinical specialty areas. As an example, a firm may be contracted to design the children’s department, but another firm may be hired to take the lead in designing the new ED. Although these multi contract arrangements may be more difficult to administrate, they can yield excellent outcomes for the specialty departments in hospitals because of the in-depth knowledge of the designers for the design needs in these unique clinical areas. A designer who is a healthcare generalist may not know the newest trends in the integration of interventional radiology and the operating suites as would a design specialist in this clinical area. Similarly, a mechanical engineer who is a generalist may not know the need to place air-handling units away from the center of the room in the labor-delivery-recovery rooms to prevent cold air from causing hypothermia in newborns. Healthcare designers must integrate some clinical knowledge with their design expertise, and often this comes from experience from other project, disseminated knowledge from the literature, or excellent interviewing skills when speaking to healthcare providers.
