1. EXECUTIVE SUMMARY

1.1 INTRODUCTION

This 95% Design Submittal was developed by Sherlock, Smith and Adams, Inc. (SS&A) under Design-Build Contract W91278-09-D-0009, Task Order No. 0005, to support the development of a 100% design for the project for “Design-Build Renovate Joel Army Medical Clinic Building 125, Ft. McPherson, Atlanta Veterans Affairs Medical Center, Atlanta, Georgia”. BLHI/SRS A Joint Venture is the holder of the Design-Build Contract. The Mobile Division of the Corps of Engineers (COE), Mobile, Alabama, is the contracting and design agent.

1.2 SCOPE

Existing Building 125 (B125) is a two-story building with partial basement that will be partially renovated for a new Veterans Affairs Outpatient Clinic (VA Clinic). The building was originally designed as a Medical/Dental Clinic for the United States Army at Ft. McPherson. Since Ft. McPherson has been shut down as part of the Base Realignment and Closure (BRAC) Program, Building 125 is being transferred to the VA by the Army as part of the redevelopment plan for the closed Base.

Work in this Project includes architectural, plumbing, mechanical, fire protection, electrical and communications design.

1.3 TASKS

As outlined in the original Statement of Work for this project, SS&A is required to:

Prepare design and construction documents for 12 Redesign Areas as listed in the Statement of Work.

Verify that all existing sprinkler heads in Building 125 are quick-response, and if not, indicate any necessary replacements.

Verify that existing egress components in Building 125 comply with NFPA Life Safety Code requirements.

Provide mechanical drawings showing the replacement of existing chiller, humidifiers and computer room air conditioning unit.

1.4 SITE INVESTIGATION

Initial site investigation was conducted by the Architect-Engineer (AE) team on 3-7 October 2011. The team documented the existing condition of Building 125, particularly in those areas being renovated under this contract. An examination of the existing sprinkler system and

Building 125, Ft. McPherson, Atlanta VAMC 1-2 egress components was conducted as part of this investigation. Refer to Appendix C4 for the Fire Protection Field Investigation Report.

1.5 ARCHITECTURAL

The total square footage of Building 125 as identified by the VA is approximately 70,000 SF. As part of this project, approximately 21,701 square feet will be renovated for clinical, administrative and support spaces for the new VA Clinic. Existing wall and room configurations will be maintained wherever feasible and practical, but substantial demolition will be necessary in some areas in order to accommodate new functions. In areas where no major renovation is to occur, work will be limited to painting the existing walls to a level five finish.

A newly constructed Welcome Center will be the focal point of the new VA Clinic at Ft. McPherson.

As the “first impression” of the Clinic, the Welcome Center will be designed with high-quality finishes for a more upscale look and feel that demonstrates the quality of the experience that the Veterans will receive at the new Clinic. Contemporary design features and free-form built-in elements will also enhance the image of a modern, patient-focused health clinic.

Each of the clinical areas to be located in the new VA Clinic at Ft. McPherson will receive newly renovated reception and waiting areas. Each new reception area will feature individual counters or stalls where Veterans and be greeted and assisted privately. Full height walls with acoustical treatments (as necessary) will be constructed between each individual reception counter. Patients will have the choice of standing or sitting at the reception counter. Check-in kiosks will be located in immediate view of the reception areas so that patients checking in via kiosk can be easily assisted if needed. New waiting areas will be constructed adjacent to all new reception areas. Finishes selected for new reception and waiting areas will evoke a warm, welcoming, and upscale facility.

See Chapter 2 for more detail.

1.6 MECHANICAL AND PLUMBING

1.6.1 Mechanical

There are limited modifications proposed for the existing HVAC systems. The Data Center/Computer room will be cooled by a dedicated computer room air conditioning (CRAC) unit which will require the addition of a dedicated dry-coolers, piping and pumps. Three CRAC units will provide N+1 redundancy with two units operating under normal load and one unit providing backup. The Data Center/CRAC unit will be connected to the emergency power system. The existing air cooled chiller serving the building is 13 to 15 years old and will be replaced with a unit of similar capacity with higher operational efficiency than the current unit.

Diffusers throughout the area of renovation (areas 1-8 and 11) will be replaced or relocated as indicated on the construction documents. It is intended to limit the HVAC modifications to redistribution of air flow by relocation of diffusers, simple modification of ductwork and possibly relocation of terminal units, however where space temperature or airflow control for the renovated spaces is different than that of the existing space configuration and use it may be

Building 125, Ft. McPherson, Atlanta VAMC 1-3 necessary to provide additional VAV terminal units to the system. The humidification systems will be replaced as well as the DDC system replaced. Re-commissioning of the building will be performed after all renovations are complete.

1.6.2 Plumbing

The existing domestic water and waste systems shall be capped where plumbing fixtures are removed. New plumbing fixtures shall connect to the existing domestic water and waste systems.

See Chapter 4 for more detail.

1.7 ELECTRICAL AND COMMUNICATIONS

The electrical work provided under this project will support the following changes within Building 125: (1) creation of a new main computer room and several support spaces;

(2) creation of a welcome/information center at the main entrance; (3) creation of check-in areas on each floor; (4) creation of admin offices, break rooms and conference rooms on each floor;

(5) creation of women's health suites; (6) creation of specialty exam rooms; (7) creation of a security suite with a Detention cell; (8) replacement of all existing exit signs within the building;

and (9) creation of a new electrical closet for emergency power equipment.

Minor changes to fire alarm, security and other systems are anticipated within the building to accommodate the above interior changes.

See Chapter 5 for more detail.

1.8 LIFE SAFETY / FIRE PROTECTION

1.8.1 Life Safety

This project involves renovation of selected areas in this existing, unoccupied building that has three levels (Basement, First and Second Floors). It is classified as a two-story building based on the LSC definition of a building story. It is an unprotected non-combustible steel structure.

The primary occupancy classification of the facility is Business.

The existing building is Construction Type II(B)/IBC (Type II(000)/LSC). Means of egress requirements for the renovated areas will be based upon Chapter 7 and Chapter 38 of NFPA 101.

1.8.2 Fire Suppression

The existing facility is fully sprinkled with a wet pipe sprinkler system. However, basically all of the existing sprinkler heads in the facility are Standard Response Sprinklers. They will be replaced with Quick Response Sprinklers as required by the Scope of Work for this project. In

Building 125, Ft. McPherson, Atlanta VAMC 1-4 addition, the computer space in the basement will be protected by a “Clean Agent” fire suppression system conforming to NFPA 75 and NFPA 2001. Standard response sprinklers will be used in the computer room.

In addition to the above work, this project also covers relocation/addition of sprinkler heads in “renovation” areas of Building 125 where shown on the drawings. Design issues to be addressed in renovation areas include the following:

Reroute a sprinkler main in the basement so that it does not pass through the Computer

Room (B004).

Install monitored control valve(s) on water supplies to computer room sprinklers.

Adjusting/adding sprinkler heads to account for changes in location of partitions.

Compensate for changes in space occupancy hazard classifications.

Select type of sprinkler based on ceiling types and configurations.

Analyze total sprinkler water demands for newly configured systems versus original systems.

3. Interior

Building 125, Ft. McPherson, Atlanta VAMC 3-1

3. INTERIOR

3.1 GENERAL

The interior design concept for the Design-Build Renovation of Building 125 at Ft. McPherson, VAMC Atlanta was driven by several existing features and finishes already established by the facilities staff of the base facility. Sensitivity to existing finishes and the transition of newly applied finishes was an important factor when making various selections. A cost-effective approach that works with several existing finish applications such as the VCT flooring, 6” wall base, door frame paint color, wall paints, acoustical ceiling tile, medium golden oak door finish and wall protection color will make transitions easier but give the design team opportunities to introduce new applications that will give the facility a fresh new look.

Materials were selected with safety, maintenance and acoustics characteristics in mind. These materials have the ability to relate to various existing color palettes and material application conditions. Through the use of color and lighting, the main entrance lobby with its existing brick paver floor, will have a warm and welcoming feel. The main welcome center and coffee shop will be the primary focal points with enhanced detailing. Varied paint colors will be a primary and economical finish application that adds variety and interest to spaces. Wayfinding mechanisms created through the application of color or floor patterning will be incorporated in clinical areas, department entries and major circulation intersections.

The reuse of existing signage devices will be optimized. Where new is required, it will match existing. Signage system to be similar to Innerface “Signature Series”.

3.1.1 Ground Level

Interior Design parameters include renovating floors, walls and ceilings within the new optical suite. Due to the heavy use of water and wet type areas within the suite, flooring will be sheet vinyl and plastic laminate casework will have solid surface counter tops.

3.1.2 Level 1

Interior Design Parameters include the following departments:

Primary Care Clinic Teams 1 and 2 and Women's Health Suite – The majority of vinyl composition floor tile will remain as is. Where rooms change function or require new finishes applications listed in section 3.2 apply. It is understood that the goal is to optimize existing finishes but new paint will be applied to all areas. The Screening Rooms require a higher grade ACT with a .40 CAC similar to Armstrong’s “Cortega” series.

Radiology – Existing finishes within suite to stay as is, only receiving new wall paint.

Building 125, Ft. McPherson, Atlanta VAMC 3-2

The existing Building 125 is a two-story with partial basement structural steel building. The building was designed and operated as a Medical/Dental Clinic for the U.S. Army. The project was designed in 1994. As-built documents are dated 1998. The building has been operational for approximately 13 years. The VA will continue to operate the building as a Medical/Dental Clinic with several renovations/modifications. One such modification will include a Data Center/Computer Room in the basement.

The Clinic uses variable air volume (VAV) system with hot water reheat for space heating and cooling. Chilled water is provided by an existing 300-ton air cooled chiller and heating hot water by a gas fired boiler.

4.2.2 Proposed Mechanical System Modifications – 125

There are limited modifications proposed for the existing HVAC systems. The Data Center/Computer room will be cooled by a dedicated computer room air conditioning (CRAC)

Building 125, Ft. McPherson, Atlanta VAMC 4-2 unit which will require the addition of a dedicated dry-coolers, piping and pumps. Three CRAC units will provide N+1 redundancy with two units operating under normal load and one unit providing backup. The Data Center/CRAC units will be connected to the emergency power system. The existing air cooled chiller serving the building is 13 to 15 years old and will be replaced with a unit of similar capacity with higher operational efficiency than the current unit.

Diffusers throughout the area of renovation (areas 1-8 and 11) will be replaced or relocated as indicated on the construction documents. It is intended to limit the HVAC modifications to redistribution of air flow by relocation of diffusers, simple modification of ductwork and possibly relocation of terminal units, however where space temperature or airflow control for the renovated spaces is different than that of the existing space configuration and use it may be necessary to provide additional VAV terminal units to the system. The humidification systems will be replaced as well as the DDC system replaced. Re-commissioning of the building will be performed after all renovations are complete.

5.12 CALCULATION METHODOLOGY

5.12.1 Demand Load

Building 125, Ft. McPherson, Atlanta VAMC 5-5

The extent of renovation to the existing electrical distribution system is limited, with a substantial portion of load in each panelboard existing to remain. The existing load cannot be quantified very easily. Therefore, demand load calculations would not be useful at this time. However, as the design progresses, it may be possible to perform such calculations for the computer room area in the basement.

5.12.2 Fault Current, Protective Device Coordination, Arc Flash

The extent of renovation to the existing electrical distribution system is extremely limited;

therefore, we do not anticipate performing these calculations on this building.

5.12.3 Generator Sizing

Generator sizing calculations shall be provided for the new generator being provided for the computer room. A manufacturer-based sizing program will be used to perform these calculations.

5.12.4 Feeder Sizing and Voltage Drop

The extent of renovation to the existing electrical distribution system is extremely limited;

therefore, we do not anticipate performing these calculations on this building.

5.12.5 Lightning Protection

The building envelope in this project is existing; therefore, lightning protection is outside the Scope of Work. No lightning protection risk analysis has been performed.

5.12.6 Lighting

6.3 GENERAL PROJECT/BUILDING DESCRIPTION

This project involves renovation of selected areas in this existing, unoccupied building that has three levels (Basement, First and Second Floors). It is classified as a two-story building based on the LSC definition of a building story. It is an unprotected non-combustible steel structure.

Building 125, Ft. McPherson, Atlanta VAMC 6-3

6.4 OCCUPANCY CLASSIFICATION

The primary occupancy classification of the facility is Business.

6.5 CONSTRUCTION TYPE

The existing building is Construction Type II(B)/IBC (Type II(000)/LSC).

6.6 FIRE SUPPRESSION

The existing facility is fully sprinkled with a wet pipe sprinkler system. However, basically all of the existing sprinkler heads in the facility are Standard Response Sprinklers that will be replaced with Quick Response Sprinklers Heads as required by the Scope of Work for this project. The computer space in the basement will also be protected by a “Clean Agent” fire suppression system conforming to NFPA 75 and NFPA 2001. Standard response sprinklers will be used on the wet pipe sprinkler system in the computer room.

In addition to the above work, this project covers relocation/addition of sprinkler heads in “renovation” areas of Building 125 where shown on the drawings. Design issues to be addressed in renovation areas include the following:

Reroute a sprinkler main in the basement so that it does not pass through the Computer

Room (B004).

Install monitored control valve(s) on water supplies to computer room sprinklers.

Adjusting/adding sprinkler heads to account for changes in location of partitions.

Compensate for changes in space occupancy hazard classifications.

Select type of sprinkler based on ceiling types and configurations.

Analyze total sprinkler water demands for newly configured systems versus original

During the AE’s field investigation, it was found that two areas require the addition of sprinkler heads (approximately 6 total) due to previous partition and ceiling work where head adjustments were not made. These discrepancies will be corrected under this project.

6.7 ALLOWABLE FLOOR AREA AND BUILDING HEIGHT

Since there are no construction requirements in the LSC for Business Occupancy, the allowable height and area restrictions will comply with the IBC (reference Paragraph 2.1.B/VA Fire Protection Design Manual). Since the previous use of this building was Business, the new use is Business and there are no additions to the building, the height and area limitations are not impacted by the renovation work. The allowable area per floor for a fully sprinkled building of Construction Type II(B)/IBC is 86,250 GSF and the allowable building height is four stories.

This building does not exceed these limitations.

Building 125, Ft. McPherson, Atlanta VAMC 6-4

6.8 SUBDIVISION OF BUILDING SPACES

This facility is not required to be divided into smoke compartments (reference Paragraph 38.3.7/NFPA 101). Storage rooms used for general storage and maintenance shops in the renovated areas will have smoke partitions (reference Paragraph 38.3.2 and Sections 8.4 and 8.7/NFPA 101). This project does not address areas outside the renovated space/area.

6.9 SMOKE DETECTION

Smoke detectors will be provided in air supply systems having a capacity greater than 944 L/s (2000 cfm) (reference Paragraph 6.4.2.1(1)/NFPA 90A). The smoke detectors provided in the duct systems will automatically stop their respective fans upon detecting the presence of smoke (reference Paragraph 6.4.3.1/NFPA 90A).

6.10 MEANS OF EGRESS

Means of egress requirements for the renovated areas will be based upon Chapter 7 and Chapter 38 of NFPA 101.

Existing exit doors are provided around the perimeter of the building that meets the exit requirements. Existing exit stairs are provided from all floors to meet exit requirements from each level. Renovation work does not impact or change any existing exits.

The design will incorporate the following egress parameters:

The minimum width of all corridors exceeds the minimum required width of 44 inches

Corridors are not fire rated since the building is fully sprinklered (reference Exception No. 3 to Paragraph 38.3.6.1/NFPA 101)

The minimum width of all new single doors will be 3'-0" which exceeds minimum requirements

The minimum width of each leaf of any new double door will be 3'-0"

No dead-end corridor will exceed 50 feet allowed in Business Occupancies

(reference Paragraph 38.2.5.2/LSC)

The common path of travel will not exceed 100 feet allowed in Business Occupancies (reference Paragraph 38.2.5.3/LSC)

The travel distances to an exit from any point in a room will not exceed 300 feet in Business Occupancies (reference Paragraph 38.2.6/LSC)

Building 125, Ft. McPherson, Atlanta VAMC 6-5

The means of egress will be illuminated in accordance with Section 7.8/LSC.

Emergency lighting will be provided in accordance with Section 7.9/LSC.
