Imaging and procedure rooms fall into several size categories — small procedure rooms, typical imaging rooms, or larger specialty imaging rooms. Diagnostic equipment has generally become more compact over time. For example, equipment used for chest X-rays, mammography, ultrasound, and pulmonary and neurodiagnostic testing is compact and commonly mobile, requiring only a small procedure room. Most general radiographic and fluoroscopic equipment can be accommodated in a typical imaging room. Computed tomography (CT) units are also becoming more compact but require a contiguous control room. Magnetic resonance imaging (MRI) and interventional procedure suites require a larger footprint that includes the procedure room, control room, and adjacent space for equipment (or system) components. Imaging equipment may also require lead shielding, enhanced floor loading capacity, and other unique design features. The FGI Guidelines also classify imaging rooms based on different levels of patient acuity and intervention.
Healthcare facilities need to provide a sufficient number of parking spaces for patients, staff, service traffic, and the public. At a minimum, parking standards or requirements developed by local authorities having jurisdiction should be consulted since these will reflect the availability of public transportation, public parking facilities, or other alternatives. This article provides some general rules-of-thumb for estimating the number of parking spaces for patients being admitted/discharged, visitors to inpatient nursing units, hospital staff, outpatients, and emergency patients and their escorts.
Hospitals and healthcare facilities must ensure a robust, reliable telecommunications network to support every form of communication. Key spaces include a technology equipment room, a telecommunications entrance facility, and distributed telecommunications rooms.
Estimating the size of a central sterile processing department based on the number of beds can be unreliable due to the wide variation in the scope of surgical, obstetrical, interventional, and ambulatory care services at any given hospital that are the primary users. However, many hospitals require only a basic instrument processing function with two steam sterilizers and one gas sterilizer. A third steam sterilizer may be provided at institutions with high-volume surgical and obstetrical services. The following guidelines can be used to develop a preliminary “order of magnitude” space estimate for a central sterile processing department. The lower range would be used for a central sterile processing function that is contiguous with the surgical suite. The higher range would accommodate a case cart system, the storage of hospital-wide patient equipment, and additional specialized sterilization equipment.
- Minimal department with two steam sterilizers — 2,000 to 3,200 DGSF (185.8 to 297.3 DGSM)
- Average department with two steam sterilizers and one gas sterilizers — 3,200 to 4,500 DGSF (297.3 to 418.1 DGSM)
- Large department with three steam sterilizers and one gas sterilizers — 4,500 to 5,500 DGSF (418.1 to 511.0 DGSM)
Note: Department gross square feet/meters (DGSF/DGSM) represents the footprint of a department or functional component and includes the net area of the individual rooms as well as the space occupied by internal circulation corridors, walls/partitions, and minor utility shafts. More detailed information can be found in the SpaceMed Guide.
The space required to accommodate parking lots and structures on a healthcare campus can be substantial. When it comes to staff parking, the space is greater than that required for his or her office. The guidelines shown below can be used for preliminary space estimates. WGI, Inc. — a parking specialty firm — cites an average size of 334 gross square feet (GSF) or 31.0 gross square meters (GSM) per parking space and a median construction cost of $27,900 USD per space (2022) based on their database of hundreds of completed parking structures.
Sometimes a preliminary space estimate is needed to evaluate location alternatives, conduct a feasibility study, or develop a preliminary cost estimate for construction or renovation. Once the number of procedure rooms is determined, an estimate of the total footprint required for the diagnostic imaging suite can be made using the range of DGSF (DGSM) per procedure room shown in this post.
