These bracketed sections can be left remaining in the PWS, or removed depending on the site specific conditions and needs. Please remove all brackets and italicized font before issuing to the Contractor.


1.     GENERAL

This PWS provides minimum criteria for “sufficiency of care” to provide a rapid response to the expected need, therefore, it is critical that local authorities and/or Area Fire Marshal are involved in the development of the design and acceptance of this site.

The Contractor shall retrofit the selected space into an Alternate Care Site (ACS) to serve ambulatory, non-COVID-19 patients. This effort is to provide an Alternate Care Site meeting basic healthcare functions with an emphasis on patient care, infection control, fire protection, and life safety.  Advantages to the user of this space are greater patient density enabling a reduction in healthcare workers and faster construction time as well as greater use of prefabricated construction (e.g. Portable Bathroom Trailers, conex for support service spaces etc.).  The ACS shall serve as a satellite patient ward supported by a nearby full service hospital. 

[The Contractor shall be responsible for the demobilization and removal/disposal of all facilities and equipment upon completion of this work and the restoration of the permanent site as necessary in order to return it to its original state.] – This can be edited, removed, or included as contract and site lease agreements dictate.


Concept of Operations

The space shall serve as an Alternate Care Site (ACS) serving ambulatory, non-COVID-19 with semi-private beds segregated by temporary partitions.  Patients are considered to be NFPA 99 Category 3, which is defined as patient care “activities in which the failure of equipment or a system is not likely to cause injury to patients, staff, or visitors but can cause discomfort” (NFPA 99 para. 4.1.3). The full service hospital would provide the logistics, materials and waste management support, nutrition care etc.  All dirty and clean supplies would be transported to/from the full service hospital. The Contractor shall divide the space into “zones” as such: Zone 1 - Utility zone at perimeter, Zone 2 – Support at Perimeter, Zone 3 – (Center) – Patient Care Area. The Contractor shall provide all temporary facilities in order to execute a fully functional ACS within the convention center space. This includes, but is not limited to, toilets, showers, medical waste, pharmacy, general waste, & hand-washing facilities.

Site Modifications Required

The following are the anticipated site modifications needed to convert an enclosed open space (e.g. convention center) to an ACS.  Site selection should be based on confirming the critical technical features to achieve minimum life safety and infection control standards. 

The Contractor shall provide all necessary labor, materials, and equipment to provide the following equipment and temporary/portable facilities in order to convert the selected space into an ACS:

Patient areas/bays segregated by temporary partitions with an orientation that will maximize patient density while maintaining patient comfort, semi-privacy, and life safety requirements. Minimum area per patient space is 10 feet wide x 10 feet deep (approximately 100 square feet) to accommodate patient beds and necessary medical and non-medical equipment. Patient bays can consist of 6, 8, 10, or more beds.  The patient care module may consist of 8 or more bays to a maximum allowable boundary/perimeter meeting smoke compartment limitations per NFPA 101.  The Contractor shall provide, install, and maintain full-height perimeter walls (9 feet tall) around the module and half-height interior walls (4’ high) to divide each bay.  Wall materials shall be non-combustible or limited combustible.  Wall and ceiling finishes for room/pods constructed on-site or with solid surfaces shall have a Class A rating. Individual patient spaces/partitions may be prefabricated, constructed on site, or variations of as long as they conform to the non-combustible and patient ingress/egress requirements presented herein.

Temporary/portable hand-washing station shall have the ability to maintain hot water in accordance with all applicable codes/requirements. The Contractor shall either utilize the site’s potable water/wastewater utilities and tap into these utilities where practicable OR provide the services to provide potable water and wastewater disposal services at a rate of 15 L/per day per Patient & Caregiver. Temporary/portable structures shall be comprised of non-combustible materials and shop drawings/product data sheets shall be submitted to the Government for review and approval.

Temporary/portable bathrooms: The Contractor shall provide and install temporary/portable toilets with sinks to be located inside the space in close proximity to the patient areas. The number of toilets shall be 1 per 20 people and ADA compliance is required. The total number of temporary/portable units is based on the Contractor’s selection per the International Plumbing Code (IPC) with respect to the design/construction of the individual units (i.e. 2 toilets/sink per trailer, etc.). These temporary/portable facilities shall be tied into the existing potable/wastewater utilities where practicable. If this is not practicable, then the Contractor shall provide the services to maintain adequate potable water and waste disposal services for the duration of this requirement.

Temporary/Portable Showers: The Contractor shall provide and install temporary/portable showers to be located inside the space in close proximity to the patient areas. The total quantity of individual showers shall be based on a need of 3 people per hour for 24 hours and ADA compliance is required per IPC. The total number of temporary/portable units (i.e. 4 showers per trailer/conex, etc.) is based on the Contractor’s selection of the design/construction of the individual units.
