Performance Work Statement (PWS)

Convert a Convention Center into an Acute Alternate Care Site (ACS)

Target Audience: NFPA 99 Category 2 “Plus” Patient Space, which is defined as “activities, systems, or equipment whose failure is likely to cause minor injury of patients, staff, or visitors” (NFPA 99 para. 4.1.2) plus additional Category 1 provisions (Critical Care – risk of major injury or death) as relates to the specific needs of a COVID-positive patient on the ventilator (NFPA 99 para. 4.1.)

1.     GENERAL

The Contractor shall retrofit the selected space into an Alternate Care Site (ACS) to serve acute care (COVID-19) patients. This effort is to provide an Alternate Care Site meeting basic healthcare functions with an emphasis on patient isolation, 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 full service hospital would provide the logistics, materials and waste management support, nutrition care etc.

[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 paragraph can be removed or edited as contract and site lease agreements dictate.

2.      FUNCTIONAL REQUIREMENTS

2.1 Concept of Operations

The space shall serve as an Alternate Care Site (ACS) serving COVID-19 with isolation tents in a suite configuration for acute care COVID-19 patients.  Spaces are considered to be Category 2 “Plus.”Category 2 “Plus” is defined as NFPA 99 Category 2 (patient care “activities, systems, or equipment whose failure is likely to cause minor injury of patients, staff, or visitors”) (Reference NFPA 99 para. 4.1.2) plus additional Category 1 provisions (Critical Care – risk of major injury or death) as relates to the specific needs of a COVID-positive patient on the ventilator (NFPA 99 para. 4.1.). This Alternate Care Site (ACS) would act as a temporary satellite Ward supported by a nearby 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 facilities such as: toilets, showers, medical waste, pharmacy, general waste, hand-washing facilities, and other requirements included herein. Isolation tents shall be provided with dedicated exhaust in accordance with the following requirements.

The proposed flooring material shall be washable and cleanable while maintaining a safe, non-slip surface.

The Contractor shall provide individual room arrangements meeting patient room criteria. Arrangement of Patient care shall be such that each patient isolation pod/tent maintains full visibility from the nurse’s station. This could be, but is not limited to, a layout where there is a centralized nurse’s station surrounded by patient isolation pods/tents on three sides to form a patient “block.” The Contractor shall propose a layout that maximizes patient density while maintain ingress/egress requirements, life safety code requirements, patient access and visibility requirements, and ensures temporary/portable support facilities can be maintained in close proximity to the patient zone. The minimum corridor/walkway widths shall be 8 feet. These patient care modules can be aligned/ stacked/ arranged in rows or larger groupings to create multiple and larger capacity patient care. 

Each patient area or “block” shall contain pods/tents for isolation patients, nurse station with monitoring station, team collaboration room, laboratory, medication room, decontamination, gas cylinder storage, clean utility, staff lounge, janitors closet and all necessary  equipment (Crash cart, Blanket warmer, wheelchair, patient lift, portable x-ray and circulation, hand washing stations and vestibule for donning and doffing.  Acute patient beds need to have the capability to raise/elevate both the head and feet of the acute patient.

4.0 Mechanical

The Contractor shall provide, install, and maintain all labor, equipment, and materials as described herein: Isolation tents (grouped in suites) shall be served by an isolation exhaust AHU with HEPA filtration discharging to the outside of the site.  The Contractor shall achieve the ASHRAE 170 requirement of 0.01 inches water gauge to meet patient isolation requirement.  Each 100 square foot tent shall be provided with a minimum of 200 cfm exhaust to maintain space conditions and negative pressurization.  Make-up air shall be provided from the site’s central systems. The isolation exhaust AHU’s should be located as close to the building exterior as possible and discharge a minimum of 20ft away from the air intakes, doors and other building openings. All ductwork within the building shall be negative for infection control.  Duct to the isolation suites shall be supported on temporary supports at least 10ft above the finished floor level.  At the isolation tents, the duct shall be located inside a low partition wall along with other utility systems with an intake installed within the headboard structure.  The Contractor shall validate and, if necessary, adjust, test, and balance the existing site HVAC systems to ensure patient comfort considering the number of patients and caregivers in the site.  Space temperature requirements are 68 deg. F winter and 72 deg. F summer.  Lower than standard space temperatures are required as the pods rely solely upon make-up air for pod ventilation and conditioning.

The Contractor shall adjust, test, and balance the existing Arena AHU systems to minimize exhaust/relief air and maximize outside air to ensure sufficient make-up air is available to account for the additional exhaust at the isolation tents (100% outside air is to be achieved). This shall be performed by qualified HVAC specialist and a certified and accredited TAB specialist. The Contractor shall provide mechanical exhaust in order to route any shower, toiler, and laundry, and other applicable temporary/portable support site exhaust to the exterior or exhaust system.  The Contractor shall not utilize the isolation exhaust system for any wet exhaust (e.g. shower or laundry) as the moisture will degrade the HEPA filters.

The Contractor shall supply all temporary negative air machines/AHU’s with compatible HEPA filters. The maintenance of the existing site AHU’s is the responsibility of others.

5.0 Electrical

The Contractor shall provide, install, and maintain an NFPA 110 type 10 level 1 emergency  generator on a flatbed or on pad with skid mounted tank. The Contractor shall provide exterior switch board(s) with automatic transfer switch(es); and connect switch board to generator power and site normal power to create an NFPA 99 chapter 6 type 2 essential electrical system.
