Part 1 General

Part 2 Hospital Facility Types

ANSI/ASHRAE/ASHE Standard 170-2017 Ventilation of Health Care Facilities

Heads up: There are no amended sections in this chapter.
Appendix material, which appears in shaded boxes at the bottom of the page, is advisory only.
A1.4-1 Equipment will vary to suit individual construction projects; therefore, careful planning is important to assure the equipment chosen is accommodated in the project design.
The provisions of this chapter shall apply to all hospital projects.
An initial equipment list shall be included in the contract documents to assist in overall coordination of the acquisition, installation, and relocation of equipment.
The equipment list shall include all items of equipment necessary to operate the facility.
The equipment list shall include the classifications identified in 1.4-2 (Equipment Classification).
The equipment list shall specify whether the items are:
New owner-furnished and owner-installed
New owner-furnished and contractor-installed
New contractor-furnished and contractor-installed
Existing salvaged, reconditioned, relocated, and owner-installed
Existing salvaged, reconditioned, relocated, and contractor-installed
Existing salvaged, relocated, and owner-installed
Existing salvaged, relocated, and contractor-installed
Not-in-contract (NIC)
A1.4-1.3.1 Cable placement. Placement of cables from receptacles to portable equipment should be considered during design so that circulation and safety can be maintained.
The drawings or other project documentation shall indicate provisions for installation of fixed or movable equipment that requires dedicated building services or special structures and illustrate how the major equipment will function in the space.
An equipment utility location drawing shall be produced to locate all services for equipment that requires floor space and mechanical connections.
A1.4-1.3.2 NIC equipment. Some equipment may not be included in the construction contract but may require coordination during construction.
Equipment that is not included in the construction contract but requires mechanical or electrical service connections or construction modifications shall be identified on the design development documents to facilitate coordination with the architectural, mechanical, and electrical phases of construction.
Such equipment shall be identified in the construction documents as owner-provided or not-in-contract for purposes of coordination.
When final selections are made, the construction documents shall be revised to show the equipment placed in service and physical, structural, and infrastructure requirements needed to support the equipment.
Equipment to be used in projects shall be classified as building service equipment, fixed equipment, or movable equipment.
A1.4-2 Equipment types
  1. Building service equipment. Building service equipment includes items such as heating, ventilation, and air-conditioning equipment; electrical power distribution equipment; emergency power generation equipment; energy/utility management systems; conveying systems; security systems and devices; and other equipment with a primary function of building service (e.g., humidification equipment, filtration equipment, chillers, boilers, fire pumps, etc.).
  2. Fixed equipment. Fixed equipment includes items that are permanently affixed to the building or permanently connected to a service distribution system that is designed and installed for the specific use of the equipment. Fixed equipment may require special structural designs, mechanical and electrical provisions, shielding, or other considerations.
    • -Fixed medical equipment. This includes items such as fume hoods, sterilizers, imaging equipment, radiotherapy equipment, lithotripters, hydrotherapy tanks, audiometry testing booths, surgical and special procedure lights, ceiling-mounted surgical booms, and ceiling-mounted mechanical patient lifting devices.
    • -Fixed nonmedical equipment. This includes items such as walk-in refrigerators, kitchen cooking equipment, serving lines, conveyors, mainframe computers, laundry, and similar equipment.
  3. Movable equipment. Movable equipment includes items that require floor space but are portable. Examples are wheeled equipment (e.g., beds and gurneys), portable items, office-type furnishings, and diagnostic or monitoring equipment. Movable equipment may require special structural design or access, mechanical and electrical connections, shielding, or other considerations.
    • -Movable medical equipment. This includes items such as portable X-ray, electroencephalogram (EEG), and electrocardiogram (EKG) equipment; treadmill and exercise equipment; pulmonary function equipment; operating tables; laboratory centrifuges; examination and treatment tables; standing assist lifts; and similar equipment.
    • -Movable non-medical equipment. This includes items such as personal computer stations, patient room furnishings, food service trucks, case carts and distribution carts, and other portable equipment.
    • -Furniture and equipment size. Furnishings and equipment (e.g., beds, exam tables, exam chairs, gurneys) impact clearance requirements. As furnishings and equipment vary based on clinical needs, patient size, manufacturer, and model, it is important that furnishings and equipment be selected for planning purposes by the operator of the facility.
Close coordination of locations for and installation of major technical equipment between owner, building designer, installer, construction contractors, and others shall be required.
A1.4-3.1 Major technical equipment
  1. Major technical equipment includes specialized equipment (medical or nonmedical) that customarily is installed by the manufacturer or vendor. Examples of major technical equipment include items such as X-ray and other imaging equipment, radiation therapy equipment, lithotripters, audiometry testing chambers, computers, pneumatic tube systems, and similar items.
  2. Major technical equipment may require special structural designs, mechanical and electrical provisions, clearances, or other considerations. The facility design should accommodate paths of travel for easy removal and replacement of large equipment such as linear accelerators, CT scan equipment, and MRI equipment.
Computerized equipment, such as all imaging equipment/modalities, multiphasic laboratory analyzing units, and computers, shall be protected from power surges and spikes that might damage the equipment or programs.
A1.4-3.2 Constant power for electronic equipment. Consideration should be given to the addition of an uninterruptible power supply where loss of data input might compromise patient care.
Space for accessing and servicing fixed and building service equipment shall be provided.
The following shall be considered during facility planning and design:
Locations for placement of equipment requiring floor space and mechanical connections
Locations for the power required for electrical connections where portable equipment is expected to be used
See Section 1.4-1.3.1 (Provisions for Equipment) for drawing requirements.
