INTRODUCTION PROJECT SCOPE

DESIGN TEAM

This document is a Conceptual Design Summary which will serve as the starting point for the Basis of De-sign (BOD), a living document that will evolve through the duration of this project. This document was cre-ated starting from the following key elements of developmental discovery:

Project Kick-Off Meeting - October 17 2018

Field Survey of 4th Floor Bed Spaces Existing Conditions October 17 - October 19, 2018

It is not the BOD’s function or intent to document every element of this entire process as it is developed;

rather it is to perform as an organized summary of the key developments of the project process. In addi-tion to the BOD, total documentation of the design process consists of project minutes of meetings, nu-merous design studies and options presented for consideration.

In 2018, Bancroft AE was contracted to provide Architectural/Engineering design services for the John L.

McClellan Memorial Veterans Hospital in Little Rock, Arkansas. The main project focus is to reduce the number of open multi-bed patient rooms in Pod ‘B’ and Pod ‘C’. The design renovation is to increase the amount of private and semi-private bed spaces, provide isolation rooms to each pod, and provide private

ADA bathrooms with bathing accommodations for each bedroom. The goal is to design a more functional space addressing patient privacy, accessibility and providing a space for proper patient care and discretion.

Currently the existing pods have single bed space, double bed space and 3 person bed space without private bathing facility. The scope of design services include Conceptual Design, Schematic Design, Design

Development, Construction Document and Construction Administration services for an approximately 20,000 g.s.f. (including corridors) renovation.

The optimal solution will respond to the needs of its patients and users to the greatest extent possible creating a well balance harmony in design and end user satisfaction and staff-patients efficiencies. The A/E will work with Central Arkansas Healthcare System (CAVHS) staff, Engineering Staff, Patient Care staff and other staff as required to collect all information required to design an improved floor plan in accordance with the TIL, local, state and federal building codes and standards that correct problems with facility structure, design, workflow efficiency, security and improve overall facility operations.

EXISTING CONDITIONS

The Central Arkansas Veterans Healthcare System (CAVHS), a Department of Veterans Affairs (VA) health care provider, with two hospitals, John L. McClellan Memorial Veterans Hospital, located in Little

Rock and Eugene J. Towbin Healthcare Center in North Little Rock. The two medical center locations provide a broad spectrum of inpatient and outpatient comprehensive healthcare services through pri-mary, tertiary and long term care in the areas of medicine, surgery, mental health, physical medicine and rehabilitation, neurology, dentistry, ophthalmology, geriatrics, extended care and women’s health.

The history of the CAVHS began with Fort Logan H. Roots. In 1893, the U.S. Army chose Big Rock in

North Little Rock as the location for one of its new military posts. Fort Logan H. Roots, as it was later named, served as an important military training facility in the late nineteenth and early twentieth centu-ries. When the United States entered World War I in 1917, Camp Pike (now Camp Joseph T. Robinson) was constructed to provide the military with a larger training facility.

Fort Roots maintained a hospital, during the 1918 influenza epidemic, and barracks were converted to a hospital ward to accommodate the increased patient load. In 1921 the fort was transferred to the Public

Health Service for use as a veteran’s hospital. On April 29, 1922, Executive Order No. 3669 placed Fort

Roots under the control of the newly established Veterans Bureau. Today, Fort Roots remains an im-portant part of the U.S. Department of Veterans Affairs, serving veterans in Arkansas and surrounding states. Over the years Fort Roots has been reduced in acreage, the buildings have come and gone, many of the post’s early structures still circle the parade ground.

The Fort Logan H. Roots Military Post Historic District was placed on the National Register of Historic Places on

September 4, 1974.

In December 1945, Senator John L. McClellan announced the approval of a 500-bed hospital for veterans to be built on Roosevelt Road in Little Rock. Throughout his term in office, he continually sought to improve healthcare and benefits for veterans. Among McClellan’s last major achievements included his successful bat-tles to secure appropriation and approval for the hospital on Roosevelt Road, the John L. McClellan Veterans

Administration Hospital, completed in 1984.

This System serves as a teaching facility for more than 1,500 students and residents enrolled in approximately

65 educational affiliates; its principal affiliate is the University of Arkansas for Medical Sciences. Throughout more than 80 years of rich history, CAVHS has been widely recognized for excellence in education and re-search, and – first and foremost – for a tradition of quality and caring for more than 65,000 Arkansas Veterans annually. In 1984 the new modern 825,657sf replacement , John L. McClellan VA Medical Center was con-structed in Little Rock on the campus of University of Arkansas Medical School at 4300 West 7th Street.

As of 2014, CAVHS has 280 hospital beds on both campuses as well as a 119-bed Domiciliary Residential Re-habilitation Treatment Unit that provides long-term rehabilitative care and a 152-bed community living center on its North Little Rock campus.

CONSTRUCTION STRATEGIES

Renovating an existing structure while normal activity continues is a challenging task that must be met with advanced planning for phased implementation of the design during construction. The need for a multi-phased construction project becomes evident as clinical and facility operations must continue in existing occupied spaces during construction work without disruptions. During the early planning and design phases a process shall be developed to define the constructability from demolition to completion of construction with a compre-hensive look at the impact of each phase on the new and existing facility. To better anticipate difficulties be-fore plans are finalized and construction commences, project designers and hospital managers must carefully collaborate in developing drawings which document and detail each phase of the project. Several key goals to consider as follows:

1. Construction Phasing

Project will be required to be phased as necessary to keep facility operational at all times. Only one

Pod at a time will be under construction.

Coordination with key personnel to develop a detailed phasing plan.

Phasing to maximize efficiencies and minimize construction impact on the surrounding community.

Determine construction phase activities that can potentially disrupt existing normal operations.

Develop mitigation plan to allow operations to continue.

Study the site and surrounding areas to designate lay-out areas and on-site trailer location.

Define owner restrictions during construction.

2. Security

Construction phasing plan to designate areas of construction isolated from secure perimeter of facility.

Temporary construction fencing to be provided for safety and separation of construction site.

3. Utility Interruptions

Determine any temporary utilities necessary for facility to remain operational at all times.

Coordination required with facility management group to schedule any utility interruptions.

Time and impact of any utility interruptions to be limited.

Refer to Mechanical, Electrical and Plumbing Narratives contained in this document for additional de-tailed information regarding work related to required interruption of existing engineering systems.

RENOVATION STRATEGIES

Renovating an existing building with spatial constraints offers unique challenges to implementing the greatest amount of private/semi-private patient rooms with private bathrooms containing bathing accommodations for each room in an existing building structure. Compromise is typically the norm in planning and design of newer healthcare facilities in older structures but the function and life safety are not. Several key goals for both this renovation as well as others are addressed below:

1. Standardization

All patient rooms to receive new head walls and privacy curtains. Head walls to include minimum number of gases required per the VA Guidelines.

All new bathrooms to be ADA accessible with shower, lavatory, and water closet. The bathroom door/wall shall include accommodations to allow for the free passage for the patient lift system.

All new finishes will be required throughout in these areas.

Each patient room will have a patient lift system which will allow uninterrupted patient transport into the bathroom/shower will be required. There will be 4 new isolation rooms in each of the

Pod’s “B” and Pod’s “C”. Patient lift will follow the “H” type system above beds and a “linear” system in each bathrooms.

Gypsum walls throughout the space will require repair and painting.

Cementitious Backer Board will be used in all toilet rooms with full height wall tile.

Upgrade lighting with LED lights in patient rooms, patient toilet rooms, and corridors.

Existing ceilings will be removed and replaced with new. Replacement of ceilings in corridors will also be required in order to install modified ductwork, sprinklers, and plumbing piping.

2. Flexibility

Rooms will need to be flexible for future reconfiguration. In rooms which currently include infrastructure for “multiple” patients, the design/planning shall include provisions for leaving the infrastructure in place in order to meet a higher patient count/demand in emergency situations .

3. Surveys

Asbestos survey. The A/E will review the existing asbestos survey and determine any additional locations required to be on the asbestos survey. Asbestos abatement will follow Master

Construction’s Section 02 82 13 from TIL local, state and federal requirements .

Electrical load survey. The A/E will determine the electrical load requirements through the design process. The listing of known electrical equipment is provided to assist the A/E determines electrical requirements.

Mechanical Requirements Survey. The A/E will conduct a mechanical requirements survey of patient room to determine needs to be incorporated into the project. Consideration will include air exchange requirements, air supply, and ventilation. At this time no major systems are included only the re-distribution of the existing building’s MEP systems. The A/E will provide the station with the engineered loads required by the new renovation. The responsibility to provide the requested requirements are supported by the building power plant.

Sketch 2: November 27, 2018

During the first meeting, the preliminary design was presented to the team showing Pod “B” with Pod “C” being a mirror image. New exhaust ductwork to be provided for all new ADA bathroom with shower. Alternates were presented with the Pod “B” concept.

PRELIMINARY CONCEPTS

Conceptual Design2

Sketch 4: February 26, 2019

Further plan design enhancement is part of the design process. During the design stages, 6 private patient rooms, 4 isolation rooms, and 12 semi-private bedrooms were achievable. Each of these rooms have approximately 64 sf of private ADA bathrooms with ADA showers, ADA water closet, and ADA lavatory with a lift station in each room. The existing communal shower rooms are converted to equipment storage rooms. Each bedroom suites will have new wall finishes, new privacy curtains, and new lift stations along with new headboards. The strategy is to take advantage of existing plumbing risers and vents in the new design.

Existing branch ductwork, diffusers and grilles, supplying and returning air to the highlighted area shown below shall be demolished and capped at the mains. Existing VAV Box terminal units dedicat-ed to the highlighted areas shall also be demolished along with it’s associated piping, valving and thermostats. Based on the existing airflow rates obtained from existing as-built drawings and Test and Balance Reports, there is no significant change in air flow for the new design. Therefore the existing air handling unit systems will be re-used with no modifications.

Private/Semi-Private Bedrooms and Office Spaces:

New DDC controlled VAV terminal units with hot water reheat, thermostats, and branch piping will be in-stalled to accommodate the new floor layout. Each patient room will be zoned individually with it’s own

VAV terminal unit and thermostatic controls. New medium and low pressure supply and return ductwork will tie into the existing mains. Any existing ductwork that is deemed too small for the revised airflow rates will be replaced with new.

Isolation Room/Ante Rooms:

There will be four new Infectious Isolation rooms in each pod. The isolation rooms and ante rooms will be 100% exhaust. Exhaust for the isolation rooms will be accomplished using a high velocity mixed flow induction fan with a bag in/bag out HEPA filter. The four isolation rooms in each pod will all be combined on one fan system. The fans and HEPA filters will be designed for N+1 redundancy.

The proposed location for the new induced flow exhaust fans is on the second floor roof of the POD 2C, as shown in the photo below. The new exhaust ductwork will run down from the fourth floor into the mechanical room below and then out onto the second floor roof.

Each isolation room will be zoned separately via new bubble tight Venturi control valves on the exhaust and constant volume terminal units with a hot water reheat on the supply. All exhaust ductwork upstream of the HEPA filters shall have welded stainless steel construc-tion.

The scope of this project is to demolish electrical in core areas, corridors and patient rooms and design an updated electrical system, lighting system, fire alarm system, security and data and communications system in Pod ‘B’ and Pod ‘C’ on the 4th floor of the John L. McClellan Memorial Veterans Hospital.

Normal and Emergency 208/120V power is provided to the 4th floor Pod ‘B’ and Pod ‘C’ from the 3rd floor panel 3DH and 3DQH respectively. Emergency and Normal power for Pod ‘C’ will be provided from upgraded panels in Electrical Closet 4C-145 and new Electrical Closet 4C-145A. Emergency and Normal power for Pod ‘B’ will be provided from upgraded panels in Electrical Closet 4B-122 and new Electrical Closet 4B-120. 480/277V emergency power to plume fans, will be provided directly from the 3rd floor existing panel “NEW 277/480V”.

Upgrading the facility electric power distribution system (i.e. bringing new power to the 4th floor or to the roof), is not included in the scope of work.

Because the 4th floor electrical panels feed all the floors above (5th, 6th, 7th and 8th floors), load measurements were performed. The 4th floor electrical design includes limitations on Emergency Power in POD B. Any future Emergency Power increases in POD B for floors above the 4th floor, will need to be made available on the upper floors. POD B 4th floor cannot support Emergency Power increases to upper floors. POD B Normal power and POD C Normal and Emergency Power have spare capacity. But, future electrical load increases on upper floors must consider 4th floor loads in any electrical design.

GENERAL

PATIENT HEADWALLS

The inclusion of Patient Bed Headwalls in all patient rooms will consolidate most of the patient power requirements onto the headwalls. Initial design is to include four (4) Emergency Power and (4) Normal Power receptacles onto each headwall.

Each Headwall is feed from two Emergency Power circuits and from two Normal Power circuits, for reliability. A dimmable switch for Exam Lights and a dimmable switch for Patient Bed Lights will also be included. The Headwalls will also be provisioned for a Nurse Call module, a Code Blue Module and a Patient Pillow Speaker to access Nurse Call and Television Entertainment. Bed controls are also provided through the Nurse Call system. .

The Information Technology (IT) portion of the headwalls is described in the Communications Section.
