1. EXECUTIVE SUMMARY

1.1. Introduction and Project Background

N.K. Bhandari, Architecture and Engineering, P.C. has been contracted by the General Services

Administration (GSA) to provide Design Build (D-B) procurement documents for the renovation of the 3rd Floor of the North Building of the Centers for Medicare and Medicaid Services (CMS)

Headquarters campus located on the campus at 7500 Security Boulevard in Woodlawn, Maryland.

This renovation is the third phase in the renovation and modernization of the CMS campus as envisioned in the May 2018 Master Plan. Previous renovations provide guidance to this Program of Requirements as to spatial layout, aesthetics, and materials of construction that will bring consistency to the design and construction of the third-floor renovation.

The North Building consists of a three-story rectangular shaped building which houses Class A office space, contains an approximate gross floor area of 222,350 square feet and was constructed in early 1995. The third floor is approximately 64,000 gross square feet and consists of a core area with elevators and mechanical space surrounded by open floor plate for office and support functions.

1.2. Program of Requirements Summary

The programmatic data included in this POR has been collected through an interactive process of interviews and work sessions with the tenant agency representatives. With the information gathered, the resulting POR is a design tool, serving as the basis for a future design team’s work in the production of Design Intent Drawings and ultimately Construction Documents. This document serves to assist in assuring the new facility will perform in a manner that satisfies the programmatic design requirements for CMS.

The following process and methodology to obtain, analyze and interpret the data contained in this report:

• Members of the project team held an initial orientation meeting to review project scope

FOR OFFICIAL USE ONLY

and purpose. The objective of this meeting was also to familiarize the CMS representatives with the facility programming process.

• CMS representatives were interviewed to develop an understanding of the space requirements regarding personnel and support space. GSA authorized representatives, CMS staff and the NKB team conducted a walkthrough of the existing facilities.

• Existing building construction drawings were reviewed as provided by the GSA and on-site observations of existing building systems were performed.

• CMS staff provided staff and spatial information for the CMS Departments that will occupy the third-floor post-renovation, and design direction for General Unassigned space.

Programming information is intended to capture projected needs based on the best available current information. As the project progresses into design, program requirements shall be confirmed and updated so that the evolving design remains current with CMS program needs.

Likewise, the project must be reviewed with users at the design development and construction document stages to confirm that all program requirements have been met.

The programmatic summary is as follows:

1.3. Cost Estimate

A Rough Order of Magnitude for the associated costs of construction is based on the content of this POR. The Design Builder shall produce a cost proposal as required by GSA procedures.

The Estimated Construction Cost (ECC) with assumptions and contingencies is thought to be between $25M - $35M.

FOR OFFICIAL USE ONLY

1.4. Project Schedule

A conceptual schedule has been generated in collaboration with GSA and represents phasing and durations based on the current information available at the time of this report. The schedule is subject to change, and the Design Builder shall prepare a project schedule per GSA procedures.

2. PROJECT OVERVIEW

2.1. Project Scope

The renovation of the North Building 3rd Floor of the Centers for Medicare and Medicaid Services

(CMS) headquarters is the third phase of the implementation of a 2018 Master Plan which envisioned the housing and capital needs of the CMS Headquarters over 25 years.

The project is a Design Build effort to completely renovate approximately 63,400 gross square feet of office and support spaces on the Third Floor of the North Building and the upgrade and refurbishment of the North Building passenger elevators. Work to renovate the Third Floor and the elevators will require design and construction outside the confines of the third floor to support infrastructure or cosmetic improvements.

The work to demolish and reconstruct office and support spaces will require phasing and relocation in collaboration with GSA and CMS to accommodate staff currently housed in those spaces. It is currently envisioned that the work will occur in at least three phases, comprising of roughly half of the project scope area, such that certain staff will only require a single relocation.

The upgrades of elevators will require extensive collaboration with building managers to determine allowable outages and disruptions in service.

Collaboration with CMS vendors (e.g. furniture, audio / visual, security, etc.) is required of the

Design Builder to ensure a comprehensive design. CRI is the required vendor for all security scope. Artwork and sculptures within the area of work shall be removed and reinstalled by a professional, RFAO-approved fine arts handler during construction. Temporary storage will be in a GSA warehouse. The Design Builder shall use the Responsibility Matrix included in this

Program of Requirements, and verify requirements at the time of design, to identify third-party vendors.

The Design Builder shall incorporate the agency’s technical, functional, and spatial requirements in the conceptual design, detailed options, associated cost estimates, and in the final detailed architectural and engineering solution. The design shall adhere to appropriate codes, regulations, FOR OFFICIAL USE ONLY

GSA design guidelines, and be informed by the evolving technical and aesthetic standards being implemented by GSA and CMS in previous renovations at the facility.

2.2. Existing Building Information

Specific information regarding the existing building has been provided within the Basis of Design narratives of each discipline in this Program of Requirements. In addition to its own survey of existing conditions to verify and record information, the Design Builder shall request and secure existing building information from GSA at the outset of design. The following documents and information are available to the Design Builder:

• Building Engineering Report (Faithful + Gould, September 2017)

• CMS Master Plan (MGA Partners Architects, May 2018)

• CMS As-Built drawings (limited, does not include all systems)

• CMS CAD drawings (limited, does not include all systems)

The design and construction shall incorporate sustainable design strategies and features to the fullest extent possible, consistent with GSA P-100 requirements, however LEED certification is not required.

FOR OFFICIAL USE ONLY

4. SPACE AND OCCUPANCY SUMMARY

4.1. Program Methodology

The POR was developed from field investigations, review and subsequent discussion of the current situation and an assessment of planned future requirements.

• Field Investigation: The design team conducted a field investigation of the existing space and recently renovated floors to identify existing building conditions and the design logic of recent renovations.

• End User Interviews: Meetings were held with CMS Staff to review findings from the field investigation and to validate CMS provided information regarding space planning and program needs.

• Follow-Up Meetings: Additional meetings were held with CMS Staff to review preliminary space plans to better understand specific needs and to define the project program included in this document.

4.2. Space Measurements

The space calculations document basic Net Square Feet (NSF) defined as the space assigned to an individual function, such as an office or conference room. This number is measured from inside the walls of the space and does not include wall thickness or circulation.

The sum of all individual room/area NSF quantities for each occupant or space is supplemented by an internal circulation factor (approximately 1.6) to arrive at Usable Square Feet (USF). This circulation allowance accounts for access to and movement among interior room and areas as well as area(s) needed for internal subdividing partitions. The combination of the programmed net area and the circulation allowances results in the total Building Owners and Managers Association

(BOMA) USF for each occupant.

An additional factor is applied to the USF, to determine Gross Square Footage (GSF). GSF includes all floor area of a building that is totally enclosed within the building envelope including

Building or Floor Common Areas, such as:

• Public Elevators / Public Elevator Lobby

FOR OFFICIAL USE ONLY

• Exit Stairs

• Building Data and Communication Equipment Closets

• Electrical Equipment Closets

• Mechanical Equipment Closets

• Risers for Tenant Data and Communication Cables

• Public Telephone Alcove

• Public Men’s and Women’s Restrooms

• Custodial Storage w/Mop Sink and Recycling Storage

• Fire Closet

• Building Entry Lobby w/Security Screening Stations

• Building Circulation

Utilization Rate (UR) is used to compute the square footage allowed for space. It is a target or benchmark for the average usable square feet per person for office (including enclosed and open offices), office support space, meeting spaces, and circulation associated with those spaces. CMS has established a goal UR of 135 USF.

The UR does not apply to storage spaces or building ‘special’ spaces that unique functions that are constructed, maintained, or operated significantly differently than standard office space.

4.3. Space Program

Refer to the Appendix for the Space Program for the CMS North Building Third Floor renovation.

4.4. Functional Relationships

Black-out shades are required in conference and training spaces.

5.11. Interior Signage

The primary goal of signage is to provide information to the users and visitors of a building to facilitate wayfinding through the building. By identifying the traffic flow of an area, the positioning and quantity of signage may be determined. The signage system is directly related to the spatial structure of a location. The signage should always be located at decision points, and on long paths, the information should be reinforced to assure people they are heading in the correct direction to their destination. Identification signs should then be located at the destinations to which people have been directed, to confirm their arrival at the destination they have been seeking.

Signage Placement Guidelines:

• Signage to be placed at circulation nodes where people congregate naturally and circulate.

• Locations will be identified to make the most effective use of the least amount of signs.

• Signs will be mounted to the wall (permanent fixture), either flat or perpendicular (in blade mount).

• When there are many signs to be grouped together, these will be mounted to create an information node (they should not be touching each other).

Signage Product Guidelines:

• Provide signage per code requirements and as noted here. If there is a conflict between these requirements and code requirements, code requirements supersede.

FOR OFFICIAL USE ONLY

• Sign sizes vary depending on the type of sign that is required. The use of standard sized modules will make the signage more comprehensive since the users will look for the same format to get the information they need. Signs describing the same action should have the same size.

• Permanent rooms numbers and permanent room types are to be indicated on room signs as both tactile and raised Braille characters. Indented characters shall not be used. Braille characters may be located within an incised area on the face of a sign.

• Where International Symbol of Accessibility is required, specify raised pictogram.

Symbols, tactile and raised Braille characters are to all follow ABAAS standards.

Accessibility:

The interior signage at Centers for Medicare & Medicaid Services aims to be accessible to all. By standardizing the signage family, the facility allows an ease of recognition and prevents users from having to adapt to several signage types. Below are some of the aspects of signage that are implemented to encourage accessibility:

• Cubicle signage shall have tactile and raised braille characters

• Uniform approach to all signage in each location.

• Logical positioning of signage with respect to its function.

• Color contrast (foreground/background): 70% minimum

• Short, easy to understand message.

• Matte finish sign surface

• Installation of wall sign: median horizontal line of lettering at 62” from the floor

• Identification of a locale: on the wall adjacent to the door, at approximately two inches from the frame, on the door handle side.

• Identification of service areas made clear with the incorporation of appropriate pictograms.

7.5 System Description

7.5.1 Existing Chilled Water System

An existing central chiller plant serves the campus with two types of chilled water systems: general chilled water and ADP chilled water. The general chilled water is available all year long and is controlled with a temperature setback during unoccupied hours. The ADP chilled water is available all year long. There are two existing chilled water risers located in the North Building 3rd floor mechanical rooms. The 3rd floor is divided into two segments, segment 5 and 6. Each mechanical room has 2-1/2” ADP chilled water supply and return (ACHS/R) and 3” general chilled water supply and return (GCHS/R) risers, shown in Figure 1. The general chilled water currently serves two (2) AHUs. The existing fan coil unit that serves the telecom rooms is supplied with

ACHS/R, shown in Figure 2.

7.5.2 Existing Heating Water System

An existing central boiler plant serves the campus with heating hot water. 2-1/2” heating hot water risers are in segment 5 mechanical room that serves the North Building 3rd floor. The heating hot water serves two (2) glycol heat exchangers and the fan powered box reheat coils. The glycol heating hot water system in shown in Figure 3. The glycol heating hot water system will remain to serve the existing heating and ventilation unit.

7.5.3 Demolition Heating Water System

The existing heating hot water piping will require demolition from the Fan Powered Box (FPB) reheat coils up to the main heating hot water pipe distribution loop on the 3rd floor. Demolition of the 3rd floor heating hot water system will include, but not limited to, pipes, coils, supports, valves, controls, and other associated appurtenances.

7.5.4 New Heating Hot Water System

Provide heating hot water system for the 3rd floor to serve the new FPB with reheat coils. The new heating hot water system will include, but not limited to, pipes, coils, supports, valves, controls, and other associated appurtenances. The heating hot water system will serve the fan powered box reheat coils on the 3rd floor.

7.5.5 Existing Air Distribution System

Two (2) air handling units (AHU) currently serve the North Building 3rd floor. One AHU serves the east half of the floor and the other serves the west half. Each AHU is sized to serve the entire floor. The ductwork for both systems are interconnected for redundancy. The AHU utilizes campus general chilled water for cooling. The AHU is equipped with MERV 10 pre-filter and MERV 10 final filter for filtration. There was an abandoned steam humidifier in the AHU that was recently replaced with a UV light system. The facility maintenance personnel noted that the steam humidifier was disconnected because the steam was condensing on the cooling coil instead of humidifying the supply air. The AHU supply fan is equipped with VFD, the fan typically operates at low speeds since building is rarely at peak capacity. The supply fan, installed in 1994, is original, but some parts have been replaced over the years. While the supply fan is currently operational, it has surpassed its intended lifespan of 25 years per 2019 ASHRAE Handbook HVAC

Applications. The mechanical room is under negative pressure since the room is used as a mixing plenum for return and outside air. The return air is pulled from the ceiling plenum so all items in the ceiling plenum must be plenum rated. The outside air damper control is tied to the CO2 sensor that is mounted at the return air plenum opening.

The outside air is delivered to each mechanical room from a roof mounted Heating and Ventilation

(H&V) system, shown in Figure 5. The H&V system is equipped with MERV 10 filter. The H&V system heats the outside air with a glycol heating system located in the 3rd floor mechanical rooms.

7.5.6 Demolition Air Distribution System

Contractor will be responsible for adequately confirming system operation and configuration prior to commencing demolition work.

All branch ducts up to the main duct air distribution will require demolition. All equipment and accessories such as, but not limited to, fan powered boxes, grilles/diffusers, controls, supports, and associated appurtenances must be demolished to create space for new air distribution system.

7.5.7 New Air Distribution System

A UV coil disinfection project was recently completed, and therefore the existing UV light system will remain. Record documents can be obtained through CMS facilities group. The final filter in each AHU must be upgraded to MERV 13.

Provide FPB with reheat coils to serve the new architectural layout. Each zone must be served by a series fan powered box terminal unit with hot water reheat coils. Each FPB must be equipped with MERV 13 filters. FPBs in each zone must provide Variable Air Volume (VAV) for conditioning and maintaining the offices at a positive pressure relative to surrounding spaces and the outdoor environment. Each FPB must be provided with a local thermostat capable of local control by +/-

3 °F of room temperature setpoint. The humidity in each zone must not exceed 55 °F dewpoint temperature when occupied and 60 °F dewpoint temperature when unoccupied.

The HVAC thermal zoning must comply with Section 5.1 Mechanical Performance Table within

P100-2021v2.

Occupied office and administrative areas shall be designed with ventilation and occupancy rate shown in Section 1.1.6. All supply air ductwork shall be externally insulated. Internal duct liners shall not be used in supply or return ductwork.

The 3rd floor pressurization must comply with Section 5.1 Mechanical Performance Table within

P100-2021v2. The exterior zones shall be maintained at a positive pressure with respect to the outside to mitigate outside air infiltration and moisture migration through the building envelope.

FOR OFFICIAL USE ONLY

7.5.8 General Building Exhaust

The restroom and janitor spaces are served with the general exhaust system. General exhaust fans are scheduled from the BAS scheduler. Existing exhaust fans will remain in service to serve

3rd floor restroom and janitor spaces.

7.5.9 Telecom Rooms

The telecom rooms must be served by a dedicated fan coil unit (FCU) that utilizes the ADP chilled water (ACHS/R) for cooling source. Each FCU must have a dedicated thermostat and be integrated into existing Building Automation System (BAS).

7.5.10 Mechanical Rooms

The mechanical rooms serve as an air mixing plenum, which does not adhere to the current code specified in P100-2021.v2 section 5.3.3.2 regarding outdoor air intake locations. However, since this building is already existing and designed in this manner, the replacement of AHUs and updating controls are not within the scope of this project.

7.5.11 Electrical Rooms

The electrical rooms are equipped with a constant exhaust ventilation system that draws makeup air from the return air ceiling plenum. The exhaust fans are constant air volume and operates 24/7 all day. The existing exhaust fan will continue to operate and serve the electrical rooms on the

3rd floor.

7.5.12 Elevator Machine Room

Provide mechanical upgrades in the elevator machine rooms to meet current International

Building Code and ASME A17.1 requirements. The elevator machine rooms are conditioned with existing ADP chilled water fan coil units with exhaust ventilation. The existing FCUs are at end of useful life. Demolish existing FCUs and provide new chilled water FCU.
