1. Introduction

1.1 Background

The Harold Washington Social Security Center (HWSSC) is a delegated single occupant office building that serves as the headquarters for the Social Security Administration's Regional Office. The building was built by the government in 1975 to meet the requirement of its current occupant, the Social Security Administration. It consists of ten stories and a basement/lower level below grade. It is constructed of a composite steel, reinforced concrete structural frame clad in precast concrete panels and a custom designed glass and spandrel curtain wall. The building is surrounded by a large plaza. The HWSSC was named after Harold Lee Washington who gained national prominence as the first African American Mayor of Chicago, serving from 1983 until his death in 1987.

The HWSSC occupies a city block bounded by Madison Street on the south, Washington Boulevard on the north, Jefferson Street on the east and Des Plaines Avenue on the west. The SLI score at this location is 86. It has a National Historic Register Rating of 5 as it has not been evaluated. The entire elevated train and subway system serves the area, with numerous stops throughout the Loop. Bus service is also available. Metra, the regional rail authority, has downtown stations for each of its lines. There are also 12 underground parking spaces in the building, assigned to building tenants.

The Social Security Administration currently has three offices in lease space in downtown Chicago; The Office of the General Counsel (OGC), Office of Hearing Operations (OHO) Regional Office, and the National Hearing Center (NHC), at 200 W. Adams occupying a total of 61,155 usf. The lease space is located half a mile from the federally-owned Harold Washington Social Security Center (HWSSC), in which operations and maintenance have been delegated to SSA. This project will move the three offices onto the 6th Floor of the HWSSC, reducing the footprint of the three offices from 61,155 usf to 53,703 usf.

The result would be a lease cost avoidance of $2,232,721 with a 22% reduction in square footage. In addition, all three offices have participated in a GSA conducted workplace engagement. Taking advantage of this opportunity to create a workplace that encourages collaboration, improves productivity, and improves space utilization will also save taxpayers money.

Step 3: Prepare and evaluate the concept floor plans

Develop two (2) concepts for the space layout of OHO RO, NHC, and OGC. Evaluate the advantages and disadvantages of each to select the final floor plan. Prepare engineering narratives and ROM cost estimates for each concept proposal.

Step 4: Develop the construction documents

With the final floor plan selected, develop the construction documents for the renovation of the 6th Floor that will be used to procure the Construction Manager as Constructor (CMC). Prepare engineering narratives and cost estimates for tenant fit-out.

1.4 Project Goals

This project provides the Government the opportunity to improve the utilization of space and relocate multiple Social Security Administration offices from lease space into a federally-owned building. The government will achieve savings due to lease cost avoidance, improved space utilization and consolidating similar functions in the building. This project will assist in maintaining the building as a core performing asset and thereby improve revenue generated for the Federal Buildings Fund.

Minimize disruption to SSA mission related customer services and building occupants.

Lease Cost Avoidance: Realize lease cost savings as soon as possible.

Optimize the utilization of a core performing asset for GSA and SSA.

Promote new office concepts and strategies as well as GSA Workplace Principles.

Work closely and collaboratively with the SSA facility management staff, leveraging their knowledge of the building.

3. Executive Summary

AECOM was issued a contract by the GSA on May 7, 2018 to develop construction documents for the renovation of the 6th Floor of the Harold Washington Social Security Center (HWSSC). This renovation project will relocate three SSA component organizations (the Office of the General Counsel (OGC), Office of Hearing Operations (OHO) Regional Office, and the National Hearing Center (NHC), from lease space into a federally-owned building. AECOM’s development of construction documents will be a continuation of the workplace engagement study, also performed by AECOM, which investigated work patterns and defined the programmatic needs for the project.

The AECOM team reviewed existing documentation and performed a visual observation of the existing conditions at the HWSSC on May 30 - 31, 2018. Individual programming meetings were held with OGC, OHO, and NHC on June 27 - 28, 2018 to validate programming information and space requirements.

Two options were developed for the floorplan layout of the three different SSA component organizations for the 50% Concept Design submission on July 20, 2018. The GSA and SSA selected the Option 2 floorplan that adjusted the ALJ office sizes from 100 sf to 120 sf.

The Option 2 floor plan has been finalized after incorporating the review comments from GSA and SSA, and was included in the 100% Concept Design submission and will be developed in future submissions.

4. Existing Conditions

The following is a summary of the AECOM team’s review of existing documentation and field observations of the Harold Washington Social Security Center that occurred on Wednesday, May 30 and Thursday, May 31, 2018. The existing conditions were documented through visual inspection of the 6th Floor and support spaces. All available drawings and reports were shared by the GSA and reviewed by the project team.

4.1 Architecture

4.1.1 Floor Plate

The HWSSC has an uncommon floor plate. A central core of building services including vertical circulation and restrooms is typical in high rise construction; however in this location that core has been divided into four blocks and pushed to the exterior of the building. The core elements at the East and West sides of the building are connected by a corridor. The corridor connects the core elements on that side of the building and provides access points to the tenant space on the floor. The decision to do this will open the entire floor plate up with no interruptions, aside from the columns.

It also reduces the area available for exterior windows, as those core building elements typically require solid walls.

Figure 2 shows:

Usable square footage of the typical plan (light grey)

Vertical Circulation – Stairs (blue)

Vertical Circulation – Elevators (orange)

Restrooms & Building Services (dark grey)

When the core of the building is broken up in this manner, it caters well to a single tenant occupying the space. This was likely the intent during design of the original building when the Social Security Administration was the prime tenant.

The usable floor plate is supported by a 10 x 8 grid of interior columns. These columns have a typical 30’-0” x 30’-0” spacing. The columns are structural steel ‘W’ member framing with light gauge framing

Page | 7 and gypsum board surrounds. These surrounds are typically 2’-10” x 2’-10” and are sometimes used to hide vertical piping and conduit.

4.1.2 Open Office

4.1.3 Ceilings

The very regularly spaced floor plan for the HWSSC has a matching regularly spaced ceiling. An uncommon 5’-0” x 5’-0” staggered grid spacing was used throughout the floor. This grid continues uninterrupted throughout the open floor plan. 2’-0” x 4’-0” fluorescent luminaires are spaced regularly in this grid. The existing grid is mounted at 9’-4” above finished floor.

4.1.4 Floors

The existing floors are concrete with various floor finishes: carpet, carpet tile, vct. The existing carpet is approximately two years old and in good repair, and therefore will be reused to the greatest extent possible.

4.1.5 Walls

The existing divisions within the space are completed with modular partitions. These partitions are mounted to the floor and extend to, but not through the ceiling. These partitions are used to create offices, conference rooms, equipment rooms, etc.

The only walls that break the ceiling plane are those of the building mail shaft. These walls run deck to deck and must be maintained as fire rated construction. These shaft walls are constructed with 4” thick CMU with a plaster skim coat on the office side.

4.2 Interior Design

Most walls and interior construction, not a part of shared public space or shared corridors, will be demolished. Some architectural elements and finishes will remain:

Existing DIRTT modular walls will be removed.

Existing underfloor Walker duct system will remain and power/data will be pulled to new location for new plan layouts. Existing abandoned wiring is to be demolished.

The existing Mail Room and door to the room will remain. The shaft opening will be closed off.

Existing carpeting to remain.

Existing ceiling tile, grid, and lighting will be demolished.

4.3 Structural

The 6th Floor of the Harold Washington Social Security Center building is composed of steel framing supporting a 5-1/2 inch thick concrete, composite slab. The steel framing is supported by steel columns, which are typically spaced at 30 feet in each direction.

4.4 Mechanical / Plumbing

4.4.1 HVAC

The existing air distribution system at the Harold Washington Social Security Center (HWSSC) is a fan-powered variable air volume (VAV) system. Primary air supplied to these fan-powered VAV boxes is zoned internally and externally. The external zone fan-powered VAV boxes are approximately 700 CFM of total air supply; with primary maximum/minimum airflow of 450 CFM/60 CFM. These boxes are fitted with electric reheat coils. Supply air from these boxes is delivered through linear diffusers along the perimeter of the building. The interior zone is supplied by 1,500 CFM fan-powered VAV boxes; with primary maximum/minimum airflow of 600 CFM/120 CFM. These internal zone boxes are fitted with chilled water cooling coils on the plenum intake of each fan-powered box. Of these boxes, zones that may be prone to overcooling are additionally equipped with electric reheat coils on the discharge of the VAV box. Supply air is delivered through linear diffusers running east-west in a consistent pattern across the internal zone. The original design of the VAV system included supplying 38°F primary air to the VAV boxes from the central air handler, this air would be mixed with the warm plenum air in order to provide 55°F to the space for cooling. When the implementation of the design wasn’t achievable due to the primary air not being able to be delivered at 38°F, the chilled water coils were added to the VAV boxes in order to precool the plenum air so that the VAV discharge air would still be supplied to the space at 55°F.

Independent supply and exhaust ductwork risers serve the toilet rooms and common areas. Toilet rooms systems are constant volume and appear to provide sufficient conditioning and ventilation. The existing toilet room HVAC systems are to remain.

Additional heating for the perimeter is provided by heating water finned tube radiation. Multiple heating water risers serve the building and are zoned by exposure. The finned tube radiation system is to remain.

4.4.2 Plumbing

The existing core toilet rooms are to remain; no work is scheduled for these areas. Similarly, the existing electric water coolers on the 6th Floor will also remain.

4.5 Electrical

4.5.1 Power

The electrical distribution in the Harold Washington Social Security Center is an uncommon system. The service provider Commonwealth Edison (ComEd) has four (4) rooms per floor that provide power to the four (4) electrical rooms that are adjacent to the ComEd rooms. The ComEd vaults are stacked throughout the building and each has transformers owned by the utility. These are only accessible to ComEd personnel. There are isolated ground panels, they are the “A” panelboards, (the “A” stands for Automation) one in each electrical room. There are also two (2) non-IG panelboards labeled as “R” (the “R” stands for Receptacle) panelboards for other receptacles in each electrical room. They are fed by different transformers in the ComEd vaults. There are distribution panels in each of the 6th Floor electrical rooms (I-line type) which feed panels on the 5th, 6th and 7th Floor electrical rooms directly above and below. There are 480/277v panelboards (Siemens) that were installed in 1998 to provide power to the new VAV boxes that were part of a HVAC upgrade project. There are only two of these panelboards, one in the north and one in the south electrical rooms. Surge Protection (SPD’s) was installed in a previous project; however, it was only installed to protect the isolated ground “A” panelboards, which are supposed to provide power to computer receptacles. Probably because all the pole space was used for branch circuits in the West closet “A” panel, it was not provided with an SPD. The other “R” panelboards in each closet do not have SPD’s. All 208Y/120V-3PH-4W branch circuit panelboards and breakers were replaced within the last 10 years. The branch circuit wiring was replaced 20 years ago. There is still low voltage and power cabling in the floor duct system that is abandoned. There are no Arc Flash labels on any of the electrical equipment.

4.5.2 Lighting

The existing luminaires are 2’x4’, 3-lamp acrylic lensed. Currently, there are only (2) 28 watt T8’s in each luminaire. Along the North and South glass exterior walls are 2’x3’ T8 luminaires. The public (core) areas have 2’x2’ luminaires and ceiling grids. The existing lighting controls are four (4) Schneider Square D 480Y/277V-3PH-4W NF panelboards with Powerlink G3 controllable breakers, which provide lighting branch circuits to each quadrant of the floor. The floor is programmed to a timed schedule, but if someone is staying afterhours, there is an override switch right outside each of the four (4) electrical rooms. The override switch only controls that quadrant of lighting. Emergency luminaires are Night Lights, which are on 24/7.

4.6 Fire Protection

4.6.1 Fire Suppression

The building is provided with an existing automatic sprinkler system throughout. There is an existing 8-inch incoming water line that provides water to the building through a 750 GPM fire pump on the basement level. The pump feeds two separate 4-inch risers that supply the basement through the EMR’s at the roof level of the building. Each floor has two separate risers, one on the west side of the building and one on the east side. The risers have floor control assemblies on each floor to then feed the sprinkler heads on either the east side or west side of each floor. On the 6th Floor, 2 ½-inch mains come off of the riser feed a gridded sprinkler system that is connected with 1 ½-inch branch lines. Standard spray ordinary temperature pendent sprinkler heads are provided on most of the floors. Electrical rooms, mechanical rooms, and other similar rooms without acoustic tile ceilings are provided with upright intermediate temperature standard spray sprinkler heads for ordinary hazard group 1 coverage.

4.6.2 Fire Alarm

The existing fire alarm system in the building consists of a Siemens system with a Fire Finder XLS main fire alarm control panel. The fire alarm system also provides mass notification voice communication only, no visual mass notification specific strobes are provided in the building. Two vertical network risers are installed from the main panel, one on the east side of the building and one on the west side of the building. Each floor has two fire alarm remote panels that connect to the respective network riser, one located in the west telephone closet and one in the east telephone closet. The 6th Floor is provided with initiating devices, such as pull stations outside each stairwell and inside the offices at each exit door, duct detectors, waterflow and tamper switches for the two floor control assemblies, smoke detectors over

Fire alarm audible and visual devices are provided throughout the existing open office floorplan as well as in the corridors and restrooms. Class A circuits are shown on the as-built drawings to provide a loop from the devices back to the remote fire alarm panel. Firefighter telephones are provided in the stairwells and in the elevator lobbies.

4.7 Environmental

A previous asbestos assessment report had been conducted in the HWSSC building: the Asbestos Reinspection Report of the Great Lakes Program Service Center, Harold Washington Social Security Center located at 600 West Madison Street, Chicago, Illinois 60661, prepared by the United States Public Health Service, Federal Occupational Health and prepared for the Social Security Administration, dated August 5, 2015 (“the 2015 Report”), obtained documentation regarding previous asbestos-containing materials (ACM) surveys at the building and specifically on the 6th Floor.

Based on the 2015 Report, several previously-identified ACM were identified on the 6th Floor.

Disturbance and/or removal of these materials will require abatement by a licensed asbestos abatement contractor prior to buildout of renovation activities. These materials are listed below:

Black trash chute mastic, classified as nonfriable, in the janitor closets in basement and first through tenth Floors has been found to contain 25% Chrysotile asbestos. If this chute is to be disturbed on the 6th Floor, the mastic will require abatement by a licensed asbestos abatement contractor.

Three types of nonfriable conduit end cap putty contain Chrysotile asbestos - black/gray (15%), brown fibrous (4-8%) and brown pliable (5-10%) are present in electrical and telephone closets in basement and floors one through ten and penthouses. Precise locations of these putties are not known, and non-asbestos putties in colors of blue, gray, maroon and red/brown are also present.

Due to electrical wiring modifications over time they potentially may be mixed in with and covering asbestos-containing putties. Therefore, all end caps should be tested prior to disturbance.

Brown/red nonfriable mastic/sealer on duct seams has been found to contain 25% Chrysotile asbestos. The material is present on air handling ductwork in the electrical equipment rooms, telephone closets, second floor mechanical space, air shafts and ROCC computer room. Most of the ductwork is wrapped in foil covered insulation and seams are not visible; therefore, all seams should be considered to have asbestos-containing mastic/sealer until further evaluated.

Drywall joint compound containing 2-5% Chrysotile asbestos has been identified in most walls in the basement (excluding the fitness center) and third floor computer room (ROCC). Asbestos-containing joint compound can potentially exist in other areas of the building and should be sampled and tested prior to disturbance on the 6th Floor.

Nonfriable yellow/cream caulk containing 5% Chrysotile asbestos was identified in pipe sleeves in the tenth floor northeast janitor’s closet and lower east penthouse in the initial asbestos inspection that was conducted in 1992. Therefore, caulk in the janitor’s closets and mechanical rooms should be tested for asbestos if disturbance or removal is planned.

The 2015 Report also included the following materials that were not tested but should be assumed to be ACM unless tested.

Fire doors in stairwells throughout the building are assumed to be ACM until tested and found to be negative or replaced. The fire retardant is a friable material that is sealed in the door casing. If the stairwells on the 6th Floor will not be disturbed no further assessment is warranted.

Mastic beneath 12-inch by 12-inch vinyl floor tile (cream with gray and brown scuffs), has not been sampled and tested and is assumed to be an ACM. The mastic is present in the basement and other areas of the building; therefore, the mastic located beneath the floor tile in the 6th Floor vending area should be tested prior to disturbance or removal.

According to the 2015 Report, the following materials do not contain asbestos. These materials were observed by AECOM during the preliminary walk-through:

Drywall ceilings in janitor closets throughout building

Joint compound on ceilings in janitor closets throughout building

Carpet mastic on 6th Floor carpeted areas

Rose baseboard throughout building

Rose baseboard mastic throughout building

12-inch by 12-inch white floor tile in vending areas Floors 3-10 (mastic may not have been tested)

Drywall in vertical lift

Joint compound in vertical lift

Wall plaster in basement corridor, auditorium, elevator lobbies, Floors 3-10

4-foot by 4-foot white fiberglass ceiling tiles in Floors 3-10, main areas

Beige cementitious spray-applied fireproofing throughout building

Drywall in hallway closets, Floors 3-10

Spray-applied fluffy white fireproofing on structural beams in air shafts

Gray/white fluffy packing in duct penetration through wall in 6th Floor janitor closet.

4.8 Telecommunications / Security

4.8.1 Telecommunications

4.8.1.1 Pathways

The existing 6th Floor telecommunications infrastructure is divided into four quadrants; North, South, East, and West with each being serviced by its respective Telecommunications Room (TR). The North and South TR are approximately sized at 8’ x 10’ and the East and West at 10’ x 11’.

Page | 13

The horizontal pathways supporting the voice and data cabling infrastructure within the 6th Floor space consists primarily of a cellular floor duct system. This is a 3-cell system with the branch runs orientated in the east and west direction across the entire floor intercepted by main trunks from each TR. Two (2) of the ducts are provisioned for voice and data. The third duct is being utilized for power. The cellular floor duct is equipped with activation points at fixed intervals along the run allowing access to the duct system for cabling of the offices and workstations.

Backbone pathways consist of one (1) 3” conduit risers installed between each TR and the SSA Data Center (ROCC) to support the fiber optic backbone cabling, a 24-strand multimode cable.

There are no conduits between TRs on the 6th Floor.

4.8.1.2 Horizontal Cabling

Horizontal cabling servicing the floor consists of Category 6 UTP for both analog voice and data.

As noted previously under pathways section, the existing 6th Floor telecommunications infrastructure is divided into four quadrants; North, South, East, and West with each being serviced by its respective Telecommunications Room (TR).

The existing Category 6 cabling is color coded by quadrant:

North Quadrant – White

South Quadrant – Blue

East Quadrant – Green

West Quadrant – Violet

Workstation and office telecommunications outlets (TO) are equipped with voice and data modular jacks that are orange in color and manufactured by AMP NetConnect SL Series.

Analog voice circuits are also Category 6 but cross-connected and converted to digital through a gateway in the TR. Only a small number of circuits are analog. These are utilized primarily for multi-function fax machines. The SSA has standardized on Voice over IP (VOIP) communications requiring data only.

4.8.1.3 Fiber Optic Riser Cabling

A 24-Strand Armored Multimode Fiber Optic cable is installed between the ROCC and each TR.

The fiber is terminated in a wall mounted fiber interconnect patch panel then cross-connected to the network switch. Overall cable jacket color is orange typically identified as 62.5/125 micron.

However, the panels are labeled as 50-micron. Fiber type will need to be verified.

No OTDR test results or data related to the fiber optic cable strands were available to review.

The condition and availability of the spare fibers could not be validated.

4.8.1.4 Telecommunications Rooms (TR)

There are four (4) TRs within the 6th Floor; 6N, 6S, 6E, 6W, each servicing their respective quadrant. The TR is typically located adjacent to the Electrical Room.

The TRs are outfitted with ¾” fire rated plywood on one (1) wall, 2” x 18” ladder rack with waterfalls, and furnished with either one or several wall mounted 19” wide open racks or one (1)

One wall within the TR is allocated for a wall mounted voice termination rack equipped with associated termination blocks. The majority of the voice termination blocks are abandoned.

Associated incoming voice cabling entering from the cellular floor system has been truncated as it enters the TR and abandoned.

No servers were located in the TRs. All servers were located in the ROCC on the 3rd Floor.

4.8.2 Security

The 6th Floor space is not equipped with security.

The building does maintain a manned security force and controls access to the building at the two entrances; main public entrance on West Madison Street, the employee entrance on West Washington Street, and the loading dock in the Basement Level. Both entrances are access controlled. In addition, the main public entrance is equipped with manned guards and screening equipment; magnetometers and x-ray machines. The loading dock overhead doors are controlled with motorized overhead garage doors and vehicle barriers.

Cameras are located in the majority of public spaces to monitor activity in and around the building.

The PBS-P100 is the official building code for the projects completed by GSA. The PBS-P100 defers to the International Building Code when a GSA specific requirement is not needed. The latest version of the IBC is 2018, and that code has been specified by the GSA for use on this project. In instances where the PBS-P100 standards conflict with the International Building Code, the more stringent requirement of the two will supersede. Code reviews for compliance with these standards will occur throughout the project.

5.2.1 Floor Plate

The new layout will use the entire 6th Floor plate. It will be divided into three distinct offices for the new tenants. Each space will retain access to the building core functions, circulation and restrooms.

The new offices will meet the ABBAS standard for accessibility requirements.

The Buy America Act will be followed for those materials and equipment specified on this project.

5.2.2 Office Space

The office spaces will be designed to meet the P100 baseline performance requirements. There are minor exceptions due to the specific tenant requests.

Sound transmission is a considerable concern from the new tenants. Due to the nature of the work performed, privacy from intruding sound is an important design factor. The majority of the offices and spaces will be constructed to an STC level of 40. This is considered by the P100 and the industry as the standard “Onset of Privacy”. There are specific offices and conference rooms in each tenant space that will be used specifically for more sensitive operations. These operations will require an increase in the standard STC to a level of 50. At this point even loud speech is not audible in the adjacent spaces. Doors and ceilings will also be treated as required to ensure that the envelope of the STC 50 office is complete.

5.2.3 Restrooms

The existing structure has restrooms already constructed for the floor. Although there is no scope in this project for modifying the restrooms, it was important to evaluate the quantity of restrooms needed.

Based on the requirements of the current code, the International Building Code v2018, there are ample quantities of restrooms for the allowable number of occupants for this space.

The new 2018 IBC has modified the required number of fixtures for the Business occupancy, lowering the requirement from previous years.

5.3 Interior Design

The Interior Design will follow SSA standards as follows:

5.4 Structural

The 6th Floor has been designed for “Office” loading and vibration tolerances. The occupancy of the space will remain as “Office” space, so no further structural modifications are required.

5.5 Mechanical / Plumbing

Due to the limited scope of the project, only the mechanical equipment within the renovated portion of the 6th Floor (finned tube, fan-powered VAV boxes, grilles and diffusers) will be directly addressed.

Mechanical and plumbing equipment outside the scope of the project will not be addressed. As the Harold Washington Building was certified LEED Gold by the US Green Building Council (USGBC) in 2012, and the building had its main mechanical units recently replaced as a result of a ESPC project, it is assumed that much of the existing central mechanical and plumbing systems meet the current requirements for ASHRAE 90.1 for energy efficiency, ASHRAE 62.1 for ventilation, ASHRAE 55 for thermal comfort, and the PBS-P100 public building facilities standards. Any new equipment for the 6th Floor fitout will not only meet the most current versions of the above mentioned standards and codes but the design will also be focused on obtaining as many points possible for a USGBC’s LEED (version 4) Interior Design and Construction (ID&C) project.

5.6 Electrical

5.6.1 Power

GSA has instructed AECOM that ASHRAE 90.1 (2013) is to be followed. This will require that 50% of all receptacles on the floor be controlled by automated means. The receptacles for computers shall not be controlled due to downloads occurring after hours. GSA has informed AECOM that isolated grounds are no longer required in SSA buildings. The existing isolated ground “A” panelboards shall still be utilized for computer loads, however an isolated ground wire shall not be provided.

A Power System Study shall be performed on the existing electrical distribution equipment on the 6th floor along with the 7th floor emergency panels, which provide back-up power to the 6th floor. Ground Fault information shall be needed for all the ComEd services which are located in four (4) ComEd vaults located on the 6th floor.

Many other power requirements found in PBS-P100 (2017) do not apply to interior renovations and shall be listed in the Waivers section. The goal of the lighting power density shall be 30% below ASHRAE 90.1 (2013).

5.6.2 Lighting

The following lighting levels as set forth in the IES Lighting Handbook, 10th edition shall be designed to;

10 footcandles in transition spaces, breakout and lunchrooms, 50 footcandles in offices, and 30 footcandles in conference rooms. The IES Lighting Handbook states that “50 footcandles is for reading of red print”, the building wide standard is to design the lighting to 50 footcandles, without the inclusion of task lighting. The Lighting Power Density for office buildings (Building method) is 0.82 watts per square foot. 30% below this will be the goal of the project, unless the Space by Space method yields a more beneficial result. The GSA has determined that the PBS-P100 level of lighting quality shall be “Baseline” for this project. Task lighting shall not be included in the lighting calculations.

The ASHRAE 90.1 (2013) requirements for lighting controls shall be met.

Daylight control of luminaires shall be investigated per IES RP-5 Recommended Practice for Daylighting Buildings. The Daylight Zone shall be designed to luminaires that are twice the height of the exterior windows into the space. ASHRAE 90.1 (2013) permits that if the luminaires within the Daylight Zone are less than 150 watts, then Daylighting is not required.

Emergency lighting shall no longer be on 24/7. The emergency lighting shall be controlled by a shunt relay to turn on when normal power is lost. The spacing of the emergency lighting shall follow the requirements of NFPA 101.

5.7 Fire Protection

5.7.1 Fire Suppression

Section 7.7 and 7.8 of PBS-P100 has requirements for fire suppression system. The following requirements will either be met with a renovated system or will remain as-is:

Automatic sprinklers will be installed throughout the 6th Floor in all areas that are being renovated. Any areas not being renovated will remain as-is.

The design team will request fire pump flow testing to confirm any updated sprinkler heads and piping arrangements necessary with a new office layout.

Any fire suppression piping specified and used shall be black steel piping to match piping throughout the building.

Minimum pipe schedule shall be schedule 40 for pipe 2 inches or smaller and schedule 10 pipe 2 ½-inch or larger.

All standpipes and fire department hose outlets will remain as-is.

Fire extinguishers are not required in office buildings protected throughout with quick response sprinklers. They should only be installed in areas such as mechanical and elevator equipment areas, computer rooms, UPS rooms, generator rooms, kitchen areas, and special hazard areas.

5.7.2 Fire Alarm

Section 7.6 of PBS-P100 has the requirements for fire alarm and emergency communication systems.

The following requirements will either be met with a renovated system or will remain as-is:

The existing fire alarm system is a mass notification style emergency communication system and the renovations on the 6th Floor will provide the same audible devices for the existing emergency communication system.

All new fire alarm wiring will be specified to be installed in conduit that is rigid metal or electrical metallic tubing with a minimum ¾-inch diameter. Six foot whips are allowed for fire alarm devices only, all other wiring shall be in rigid conduit painted red.

Manual pull stations will be provided per NFPA 72 Section 17.14. Manual pull stations shall be located within 5-feet of each exit doorway, which are the exit stairwell doors for each stair on the 6th Floor that will remain as-is. Additional manual pull stations shall be provided so that the travel distance to the nearest manual pull station will not exceed 200 feet.

Waterflow switches for the zone control assemblies shall remain as-is.

Smoke detection is currently provided in electrical closets and for fire control units in telecom closets. Smoke detectors are not required in these rooms per PBS-P100 Section 7.6.3. The 6th Floor renovation project does not include renovations in any common electrical or telecom areas, so the smoke detectors will remain as-is.

Duct smoke detectors must meet all requirements in NFPA 90A. The existing duct detectors on the 6th Floor are remaining as-is and will not be changed.

Visible notification appliances must be installed in only public and common areas, they are not required to be installed in individual offices.

The existing selective evacuation plan on the 6th Floor will be used with any new devices provided. The existing “fire zone” and “safe area zone” messages used throughout the building will be implemented in any new speaker circuits and visible alarm notification appliance circuits will not be activated on floors designated as safe area zones.

Mass notification voice activation system is provided throughout the building. Only mass notification voice messages are broadcasted throughout the building. Visual notification appliances shall be the same type as used for the fire alarm, however they must not be identified by the word “fire”. The new 6th Floor layout will follow the same fire alarm devices from the rest of the building, with voice mass notification but no visible mass notification.

5.8 Environmental

Per PBS-P100 Section 1.9.4, modernizations of occupied spaces must include the removal of all asbestos-containing material (ACM) that has the potential for future disturbance both through normal occupancy, and during future repairs, maintenance, or alterations. Enclosure or encapsulation of such ACM is prohibited.

Also, paint must be tested for lead content when alterations or demolitions require the sanding, burning, welding, or scraping of painted surfaces. Lead-based paint controls must be implemented in accordance with 29 CFR 1926.62. Lead-based paint that is intact and in good condition need not be abated unless required for alteration or demolition. Construction waste containing lead-based paint must be considered hazardous waste unless testing proves otherwise.

Existing environmental information is included in Section 4.7.
