Project: Durham VAMC – Replace Pharmacy AHUs, Renovate F1204 & N1004 Compounding Pharmacies VAMC Project #: 558-17-233

WMBA #: 3251

RE: 100% Sealed Submission – Architectural Narrative

Project Scope:

This project includes the renovation of the compounding pharmacies in F1204 (the main pharmacy) and N1004 (the satellite pharmacy), including the replacement of the two Air Handling Units that serve them.

Both pharmacies were expanded and reorganized to meet the requirements of USP 797, USP 800, and the VA Pharmacy Design Guide. F1204 is located on Level 1 of Building 1, and N1004 is located on Level 1 of Building 23, which connects to Building 1. The facility’s existing asbestos reports show no asbestos-containing materials in the project areas.

Displaced storage shelving, carts, and similar equipment has been relocated in the new storage rooms. New equipment meeting USP 797 & UPS 800 requirements is provided in the Ante Rooms, Hazardous Compounding Rooms, and Non-Hazardous Compounding Room.

Life Safety Requirements & Code Analysis:

Level 1 of the Durham VAMC is classified as Business Occupancy - Ambulatory Healthcare. We have reviewed and designed around the following codes & guidelines:

NCSBC 2018

o Section 422 – Ambulatory Care Facilities

422.3 - Smoke compartments are maintained throughout the project scope as needed.

NFPA 101 – 2018

o Chapter 21 – Existing Ambulatory Health Care Occupancies o Section 8.7.1.1(2) - Storage rooms are separated with smoke tight partitions

NFPA 99 – 2018

USP 797 – Pharmaceutical Compounding – Sterile Preparations USP 800 – Hazardous Drugs – Handling in Healthcare Settings VA Design Guide for Pharmacy Service VA Design Guide for Ambulatory Care (Hospital-Based) VA Fire Protection Design Manual o Fire rated & smoke partition requirements

Main Pharmacy F1204:

The following option for the Main Pharmacy, F1204, was reviewed with the COR & Pharmacy Staff and Option 1 was determined to be the solution would best meet their needs, along with the VA Pharmacy Design Guide.

Option 1 was the chosen option, see the notes below.

Option 1 – New Pharmacy (Chosen Option):

Advantages:

o Conforms to the design specifications of the facility master plan and the pharmacy operations will not be affected by future renovations.

o Compliant with all codes, regulations, and requirements.

o Compliant with the VA Design Guide.

o Compounding rooms are large enough to accommodate future growth.

o A second restroom is added per staff comments.

Challenges:

o Requires displacement of staff, residents, and a large amount of storage space o Requires multiple phases of construction o Requires the longest construction duration

Plan Design Notes:

The design for F1204 complies with USP 797 & USP 800 because of its inclusion of a negative pressure Hazardous Drug Storage Room that connects to the Hazardous Compounding Room.

The Ante Room has a clear line of demarcation at the handwashing sink, and an area for staff to put on PPE. Per USP 797, a mobile stainless steel storage cart provides an area to wipe down any equipment in the space.

Per the VA Pharmacy Design Guide, the Non-Hazardous Compounding Room has a 7’-0” aluminum sliding door with touchless automatic operation. Due to plan constraints, the Hazardous compounding room cannot accommodate a sliding door. Per the VA Pharmacy Design Guide, a 4’-0” aluminum swing door with viewing window and touchless automatic operation is provided instead.

Pre-fabricated clean room windows are used between the compounding rooms and workstations that do not create any ledges for bacteria to grow inside the sterile areas per USP 797.

All finishes comply with the VA Pharmacy Design Guide, USP 797, & USP 800, including the specified high build glazed coating on wall surfaces as well as on the monolithic gypsum board ceilings, seamless floors with cove base. The stainless steel clean room pass throughs are mounted to be flush in the clean rooms. Finishes on the outside of the compounding area are patched to match the existing Pharmacy finishes.

Due to the limitations on the existing building and above ceiling utilities, the VA Pharmacy Design Guide recommended 9’ ceiling cannot be achieved. The highest possible height is noted, and 8’-4” ceilings are provided.

Additional Architectural USP 797 requirements met in this design:

Separate negative pressure rooms are provided for hazardous and non-hazardous compounding There are no water sources in the clean rooms Minimal equipment is provided in the clean rooms All equipment is non-shedding & cleanable There are no dust collecting ledges in the clean rooms Shelving is provided on the dirty side of the LOD for personal storage There is a cleanable storage cabinet to be used as a dedicated janitor’s closet

Additional Architectural USP 800 requirements met in this design:

A separate refrigerator dedicated for hazardous drugs is provided in the Hazardous Compounding Storage Room

There is an eye wash in the Ante Room

Additional Architectural VA Pharmacy Design Guide requirements met in this design:

All work surfaces are either solid surface or stainless steel Crash rails and wall protection are provided in storage and high traffic areas Doors entering F1204 are controlled with badge reader access

Additional Information:

The perimeter walls of F1204 are smoke tight per 2018 NFPA 101.8.7.1.1(2). The outpatient pickup windows are out of this project scope, but create a deficiency in the smoke tight enclosure from the open wells at the bottom needed for passing products through. We recommend that the facility install a smoke-rated counter coiling shutter on the Pharmacy side to maintain a smoke tight enclosure.

Additional options listed below were considered for F1204 and determined to not be in the best interest of the VA Hospital.

Option 2 – Renovating the Existing Pharmacy in Place:

*Option 2 reorganizes the pharmacy layout because we determined that renovating the existing pharmacy in its current plan layout will not meet the needs of the staff.

o This option was eliminated by staff due to the potential of taking the pharmacy out of service to renovate again in the future to meet the VA Master Plan.

Advantages:

o Could be completed in fewer phases o Least amount of construction time o Conforms to all code, regulations, and requirements o Displaces less staff for a shorter amount of time o Least obtrusive option into the existing Pharmacy o Allows space for future expansion o Requires rearranging of the break room where we cut in a door for relocation of the Chief Office o The copier adjacent to the pneumatic tube will be relocated o Displacement of staff and equipment o Requires use of temporary USP 800 compliant trailer during construction o This does not fit in the master plan and operations will be affected by future renovations o This does not comply with the VA Design Guide

Satellite Pharmacy N1004:

The following option for the Satellite Pharmacy, N1004, was reviewed with the COR & Pharmacy Staff and it was determined that Option 3 would best meet their needs, along with the VA Pharmacy Design Guide.

Option 3 was the chosen option, see the notes below.

Option 3 – Expand North, enter adjacent to Physical Therapy (Chosen Option):

o The entrance is not off the busy corridor.

o The entry vestibule allows the pressure to step down gradually from the corridor to the pharmacy.

o The Hazardous Compounding room is in a similar location, allowing the re-use of existing utilities.

o There is room for an additional glove box for future growth.

o The South portion of the Physical Therapy room will need to be renovated, including the relocation of a sink.

o The plan is reorganized, and existing utilities will need to be modified.

Plan Design Notes:

The design for N1004 complies with USP 797 & USP 800 because of its inclusion of a negative pressure Hazardous Drug Storage Room that connects to the Hazardous Compounding Room. Due to this requirement, the footprint of the pharmacy had to expand North into the Physical Therapy Room, displacing a storage room and reworking the 2 HR smoke compartment barrier. The design relocates the Physical Therapy Storage and adds the Hazardous Drug Storage Room. All finishes in the Physical Therapy Rooms are patched to match the existing finishes.

A new vestibule into Physical Therapy is provided, along with a separate entrance into the Pharmacy. The Pharmacy Entrance is separated with a vestibule to help mediate the pressure differential between the main corridor and the pharmacy.

The Ante Room has a clear line of demarcation at the handwashing sink, and an area for staff to put on PPE. Per USP 797, a mobile stainless steel storage cart provides an area to wipe down and equipment in the space.

Per the VA Pharmacy Design Guide, the Hazardous Compounding Room has a 7’-0” aluminum sliding door with touchless automatic operation.

A pre-fabricated clean room window is used between the compounding room and workstations that does not create any ledges for bacteria to grow inside the sterile area per USP 797. The workstations are located in the existing Chemotherapy room, displacing existing equipment. The footprint taken up by the workstations is made up by removing the existing Janitor’s Closet that protruded into the space. Existing equipment is relocated in the space, and all finishes in the Chemotherapy Room are patched to match the existing finishes.

All finishes in the Pharmacy comply with the VA Pharmacy Design Guide, USP 797, & USP 800, including the specified high build glazed coating on wall surfaces as well as the on the monolithic gypsum board ceilings, seamless floors with cove base. The stainless steel clean room pass throughs are mounted to be flush in the clean rooms.

Due to the limitations on the existing building and above ceiling utilities, the VA Pharmacy Design Guide recommended 9’ ceiling cannot be achieved. The highest possible height is noted, and 8’-0” ceilings are provided.

The staff workstations displaced by the Compounding Pharmacy are relocated to the area vacated by the current Compounding Pharmacy, creating new shared offices and storage space. The Omnicell Prep area has also been relocated to its own separate room in this area, and an additional Staff Toilet Room has been added.

Additional Architectural USP 797 requirements met in this design:

A separate negative pressure room is provided for hazardous compounding There are no water sources in the clean room Minimal equipment is provided in the clean room All equipment is non-shedding & cleanable There are no dust collecting ledges in the clean room Shelving is provided on the dirty side of the LOD for personal storage

There is a cleanable storage cabinet to be used as a dedicated janitor’s closet

Additional Architectural USP 800 requirements met in this design:

A separate refrigerator dedicated for hazardous drugs is provided in the Hazardous

Compounding Storage Room There is an eye wash in the Ante Room

Additional Architectural VA Pharmacy Design Guide requirements met in this design:

All work surfaces are either solid surface or stainless steel Crash rails and wall protection are provided in storage and high traffic areas The door to the vestibule entering N1004 is controlled with badge reader access

Additional Information:

The 2 HR smoke barrier separating the smoke compartments is reworked and maintained through the space. The separation runs along the south wall of the pharmacy, and a rated pass through and enclosure is used between the Hazardous Compounding Room and workstations.

Additional options listed below were considered for N1004 and determined to not be in the best interest of the VA Hospital.

Option 1 – Expand South:

o This option was eliminated since staff determined that reducing space in the Chemotherapy room is not feasible due to the space needs in that room.

o Two workstations are provided at the Hazardous Compounding room.

o The Hazardous Compounding room remains in the same location, allowing the re-use of existing utilities o There is room for an additional glove box for future growth o Space is reduced in the Chemotherapy room to the South

Option 2 – Expand North, enter through the current entrance:

o This option was eliminated since staff prefers not to enter off of the busy corridor, and the pressure differential between the two spaces is too great.

o The Hazardous Compounding room remains in the same location, allowing the re-use of existing utilities o There is room for an additional glove box for future growth o Only one workstation is provided at the Hazardous Compounding room o The space to the north will need to be reorganized o The plan is reorganized, and existing utilities will need to be modified.

o The flow through the Ante Room is not ideal due to the location of the workstation.
