1.3 PROJECT DESCRIPTION

1.3.1 Project Site

The project is located at 300 W Veterans Blvd., Building 1, Big Spring, TX 79720.

1.3.2 Functional Objective

The Big Spring Veterans Administration Medical Center was established in 1949 as the Veterans Administration Hospital. The main building is a six-story structure with light buff-faced brick exterior walls. In 1989, an addition approximately 4,800 sf was built to house the Outpatient Exam and Support facilities. The design focus for this project will be to deliver A/E services to provide interior demolition and renovation as required to bring the Outpatient reception, treatment, and support areas up to current VA standards, as well as meet end user requirements.

The new clinic will be a PACT (Patient Aligned Care Team) based on new VA design guidelines for outpatient clinics, which has an on-stage/off-stage concept. The large teamwork zone for nurses and doctors is completely separated from the patient corridor so that staff and Patients do not cross each other except in an exam room for privacy and security. Each exam room has two sliding doors for both areas, the teamwork zone, and the patient corridor. It will have a clerestory window along the patient side to bring natural light into the exam rooms and to create more openness. The women’s exam room will be relocated to this clinic area from outside the existing clinic area. A dedicated staff breakroom will be added. More natural light will be brought into the patient corridor through additional punched windows.

1.4 BACKGROUND CRITERIA

CHAPTER 4 ARCHITECTURE

4.1 GENERAL DESCRIPTION

The design focus for this project will be to deliver A/E services to provide interior demolition and renovation as required to bring the Outpatient reception, treatment, and support areas up to current VA standards, as well as meet end user requirements.

Here are the Design/Functional goals to make this project success:

• Care to the Patient

• Flexibility and Adaptability

• Privacy and Security

• Streamline Processes

• Shared open Teamwork space

• Simple and clear Wayfinding

• Promoting Health and Well-Being

4.2 DESIGN CRITERIA

4.2.1 Space Allocations

4 PACT (Patient Aligned Care Team) space module - 8 Exam rooms/Teamwork Zone with a Copy/Print room.

1 Women’s Exam room with a toilet Registration – 4 Check-in desk / 1 Check-out desk 6 offices - 1 Nurse Manager / 1 Behavioral Coordinator / 2 Social Work / 2 Pharmacist) 1 Meeting Room (4~5 people) 1 Medication Room 1 Staff Break Room 2 Toilets (Patient/Staff) 2 Storage Room / 1 Storage Closet 1 Scale Alcove

4.2.2 Internal Activities

Outpatient Clinic is medical facilities that perform procedures that do not require an overnight stay in a hospital. Patient will register at a check-in area and there is seating for them while they wait for their appointments. Each doctor works with nurses and staffs in the dedicated Teamwork Zone and will be in an exam room to meet each patient to provide preventive and diagnostic services.

4.3 BASIC ANALYSIS

4.3.1 Visual Features

Clerestory windows in exam rooms along the patient corridor side to bring more openness between exam rooms and corridor.

Additional exterior windows to bring more natural light to the patient corridor.

Wood sliding doors on exam rooms to provide extra spaces and clean appearance with acoustic rating.

4.3.2 Spatial Composition

The ‘BEEHIVE’ design model was presented by VA staff as the concept preferred for operational efficiency. The inserted picture below is representative of the design model although not a Clinical Outpatient interpretation:

Figure 1. Beehive Design Concept

Figure 2. Beehive Concept Example

The current layout/design lacks functional productivity whereas the ‘Beehive’ concept would promote inter-related patient care and discussions to occur and allow a flow of activities with a centralized observation and diagnostic focus. Reemphasized were the existing area constraints, considerations of requested staff design criteria, and functional organization would allow for the ultimate design development and would be realized and accomplished through a comprehensive concept and design process culminating in a functional, esthetic plan finalization. The ‘BEEHIVE’ design model is a good start to develop the concept design associated with the VA PACT space module based on the VA design guideline.

4.3.3 Accessibility

There are two main access points to this Outpatient Clinic Facilities. One is from the Outpatient main entrance and the other one from the main hospital corridor.

Figure 3. Accessibility Paths

4.3.4 Functional Organization

OEI introduces PACT Space Module - Separating patient and staff flows is critical to creating a more pleasant experience and reducing bottlenecks for patients, families, and staff. This separation increases efficiency by decreasing disruptions, reducing walking distances, and placing staff teamwork Zones immediately adjacent to Patient Care Rooms. This design supports rooming the patient. A dual corridor design is the preferred method of separating flows for the PACT Space Module. Veterans and families experience their care in the “on-stage” areas which include the Patient Corridor and the Patient Care Rooms. Staff prepare for visits with Veterans and families in the “off-stage” areas which include the Teamwork Zone. The staff then meet the Veteran “on-stage” in the Patient Care Room.

Figure 4. PACT Space Module Diagram with Core Components

Figure 5. Patient Care Room Example

The essential ideas of the PACT Space Module Design Guideline will be applied to this limited Big Spring Outpatient Clinic area to make sure that it meets VA requirements and the design goals as much as possible.
