Introduc on

This document has been prepared for the United States Department of Homeland Security (DHS) Headquarters Consolida on at St. Elizabeths Center Building for fi nal review by Na onal Capitol Planning (NCPC) Commission at the December 3, 2015 Hearing. GSA is seeking Final Design review from NCPC on the following elements associated with the Phase II Development of the United States DHS Headquarters Consolida on at St. Elizabeths in accordance with a project Master Plan that was approved by CFA in November 2008 and NCPC in January 2009; and in accordance with a project Master Plan Amendment approved by CFA in May 2012 and NCPC in June 2012; and in accordance with Preliminary Design approval by NCPC and CFA in September 2015.

The elements associated with this submission for Final Design are as follows:• Rehabilita on and adap ve reuse of Na onal Historic Landmark Contribu ng

Buildings 1 thru 6 and Building 8 – the Center Building;• Installa on of u li es associated with the adap ve reuse of the Center

Building; • Landscape and site work associated within the Limits of Disturbance (“LOD”)

associated with the construc on of the adap ve reuse of the Center Building.

The items above directly reference the Septermber 2015 St. Elizabeths Center Building Memorandum of Agreement (“MOA”) and the December 2008 Programma c Agreement for the Campus Master Plan.

Background and Current StatusThe goal of the Department of Homeland Security (DHS) Headquarters Consolida on at St. Elizabeths is to consolidate DHS func ons on the St. Elizabeths West Campus in southeast DC so DHS can enhanced mission eff ec veness, promote its Unity of Eff ort ini a ve, eliminate redundancies, improve effi ciencies, gain greater synergies, improve u liza on of space, and reduce long-terms costs to the maximum extent prac cable, all while revitalizing St. Elizabeths west campus, a long-neglected Na onal Historic Landmark campus.

To date Phase I of the DHS Headquarters Consolida on at St. Elizabeths project is complete with United States Coast Guard occupancy at the West Campus, approximately 1.36 million GSF of new construc on completed and six historic buildings have been rehabilitated. Phase II of the project has been ini ated with the Center Building rehabilita on design underway and construc on planned for December 2015 - 2017. GSA an cipates other Phase II projects to commence in the near term with the construc on of the I-295 Interchange and Access Road through Shepherd Parkway and Central U lity Plant Phase 2 to commence upon receipt of funding and comple on of design eff orts.

Enhanced PlanIn summer 2014, DHS and the General Services Administra on (GSA) in coordina on with the Offi ce of Management and Budget (OMB) re-evaluated the St. Elizabeths plan of record and established the Enhanced Plan. The Enhanced Plan will achieve the above stated goal in a more effi cient and cost-eff ec ve way by reducing the overall footprint and accelera ng the delivery meline, while also saving taxpayers hundreds of millions of dollars in construc on and other costs.

In order to implement the Enhanced Plan, GSA and DHS will amend the 2012 St. Elizabeths Master Plan in 2016 to refl ect the implica ons of the Enhanced Plan including eliminate the use of the East Campus North Parcel, review transporta on impacts associated with increased staff density on the campus, reduc on of the overall footprint and update the implementa on schedule and construc on phasing of the project.

A transporta on study is currently underway to: 1) evaluate the impacts of the Howard-Coble Act, 2) analyze the transporta on impacts of the Enhanced Plan, and 3) update the Transporta on Management Program (TMP) in support of the Enhanced Plan. The transporta on study and associated TMP are an cipated to be complete in spring 2016 and will be incorporated into the Master Plan Amendment and NEPA eff orts slated for comple on in 2016.

Howard-Coble Act. On December 18, 2014, Congress approved the Howard-Coble Act (Act), a law which included s pula ons for providing USCG or DHS access to addi onal spaces in the NCPC previously approved Gate 4 Parking Garage. Accommoda ng the act does not require GSA to design and construct addi onal parking to accommodate Center Building employees. The GSA Administrator, in coordina on with DHS, is required to submit a report to Congress no later than December 18, 2015. GSA has encouraged Coast Guard, and DHS to work with GSA, NCPC, and DDOT to responsibly implement the Act.

The approximately 775 number of seats in the Center Building will be allocated approximately 194 parking spaces in the Gate 4 Parking Garage at a 1:4 parking ra o consistent with the 2012 Master Plan Amendment. The parking garage at Gate 4 was built out in its en rety rather than in phases and can accommodate more cars than were needed by the ini al Phase 1 occupancy of the campus. The Gate 4 garage has approximately 1,098 unassigned parking spaces and will be able to accommodate both the 194 parking spaces assigned to the Center Building and approximately 900 spaces to respond to the Howard-Coble Act. It is not yet known if addi onal parking spaces will be needed through the Enhanced Plan but the transporta on study underway and the Master Plan Amendment will help to address those poten al needs.

OVERVIEWThe St. Elizabeths West Campus was designated a Na onal Historic Landmark in 1990 and is listed in the Na onal Register of Historic Places. The Center Building is a Contribu ng Structure to the NHL District and has served as the main pa ent treatment and administra ve building for the “Government Hospital for the Insane” (later St. Elizabeths Hospital) established in 1852 by the US Congress and President Millard Fillmore un l the mid-20th century. As the na on’s fi rst and only federal mental ins tu on in 1853, St. Elizabeths served as a na onal role model and provided the best care, condi ons and treatment for its pa ents. The St. Elizabeths campus is spectacularly sited on a ridge overlooking the confl uence of the Anacos a and Potomac Rivers and the monumental core of the City of Washington. The 176 acre West Campus was designated as the loca on for a consolidated headquarters for the US Department of Homeland Security (DHS) in 2008 and the Center Building takes “center stage” on this campus oriented in a manner that is essen ally on axis with the US Capitol dome. This submission includes only the Adap ve Reuse of the Center Building, the oldest structures on the West Campus and the landscape and site work associated within the Limits of Disturbance (“LOD”) associated with the construc on of this project.

The Center Building is actually a series of seven buildings, constructed between 1853 and 1884 with wood frame structure, masonry bearing walls and sloped metal roofs. Although some improvements and moderniza on took place in the ensuing years, these buildings remain in much the same way as originally constructed. These buildings, Buildings 1 thru 6 and Building 8 (1895), contain approximately 273,000 gross square feet on two to four fl oors - depending on the wing - plus basement. Building 7, built in 1871, was razed in 1965. This assemblage of buildings, which consisted of pa ent rooms facing north and south along double loaded corridors, stretches nearly 1000 feet and is essen ally symmetrical in layout and massing. The architect for this Gothic Revival style complex was Thomas U. Walter, who is noted as the 4th Architect of the US Capitol building and responsible for the design of the Capitol dome.

It is important to note that the design and composi on of these ini al buildings was based on guidelines prepared by Thomas Kirkbride, who was a physician, advocate for the mentally ill, and founder of the Associa on of Medical Superintendents of American Ins tu ons for the Insane, a precursor to the American Psychiatric Associa on, in 1851 to provide for the “ideal moral treatment program” for people suff ering from mental illness. These guidelines advocated unique building plans providing ample natural light and air and maximizing views of the surrounding landscape. These guidelines are as applicable today in most buildings and in par cular modern work place environments which are evident in the concept design presented in this submission.

Based on the 2008 St Elizabeths Master Plan and the 2012 Master Plan Amendment, the Center Building has been designated as the loca on of the main secretariat offi ces for the DHS and will house the offi ces of the DHS Secretary, Deputy Secretary and related administra ve components. This proposed project will rehabilitate the historic hospital, vacant for decades, for its new use as the headquarters for a federal agency. The basic design intent and performance requirements documented in this submission are to meet the basic objec ves of the government. Simply stated, these Project Goals are:

• Preserva on – To respect architecturally signifi cant parts of the exis ng buildings, par cularly in the Zone 1 preserva on areas in Buildings 1 & 2;

• Flexibility – To provide modern fl exible work places for tenant groups, complying with accessibility, life safety and security requirements;

• Sustainability – To incorporate environmentally sustainable design with the goal of achieving LEED Gold cer fi ca on.

EXISTING BUILDING CONDITIONIn the mid-20th century, the administra ve and residen al func ons were moved from the Center Building and the basic mental care facili es relocated to a new hospital on the East Campus and the opera ons transferred to the District of Columbia Department of Mental Health in 1987; the Center Building was essen ally closed up and abandoned at that me. In January 2001, the US Department of Health and Human Services declared the west campus as “excess property” and transferred the exis ng buildings and grounds, including the Center Building to GSA. The Center Building was stabilized and exterior openings were boarded up in 2004 in an cipa on of future adap ve reuse. In 2010, a Historic Structure Report (HSR) was prepared detailing the exis ng condi ons, documen ng the building’s history and recommending preserva on treatments for the building. Unfortunately the vacant building has further deteriorated with extensive water infi ltra on and ongoing environmental and structural damage. From 2010 to 2015, the building con nued to experience accelera ng deteriora on and it has been observed in a few loca ons recent addi onal fl oor collapse and the loss of masonry on the inside of the exterior walls, primarily in the oldest por ons of the building.

Consequently, based on extensive engineering surveys and studies over the last 5 years, it has been confi rmed that the exis ng interior masonry and wood frame structure is in extremely unsound condi on and no longer viable to support contemporary building code and programma c requirements for federal offi ce use. It was determined that all the deteriorated structural interior components and roof will need to be removed, which, unfortunately, will also impact the interior details, such as decora ve plaster and wall fi nishes. However, the exis ng exterior masonry walls and the inherent massing, the major exterior character defi ning elements of this building, are in fair condi on and can be retained, restored and rehabilitated as a part of this undertaking.

Basically, this project entails the integra on of a completely new building within the envelope of the original and restored façades. Cri cal to the project’s success is not only the preserva on of important historic fabric, but the op mum interplay between historic planning ideals and modern, effi cient workspace. This proposed design submission builds upon the considered strategies presented in the master plan and the preliminary design, focusing upon key elements including::

• To the extent possible, incorporate the historic preserva on recommenda ons as outlined in the Historic Structure Report;

• Refi nement of the structural system to op mize interior planning and constructability while effi ciently suppor ng the historic masonry facades including incorpora on of progressive collapse requirements;

• Enhancement of the subgrade construc on to stabilize the building, minimize disturbance to the masonry facades and mi gate poten al water intrusion;

• Provide a long las ng, low maintenance, modern roofi ng and drainage system, enhancing energy effi ciency as well;

• Improvement of the exterior wall design and windows to fi nd the right balance between historic preserva on, thermal barrier and waterproofi ng including the restora on or replica on of the historic, character defi ning double hung windows;

• Development of integrated interior planning concepts that maximize fl exibility, individual user control, and support of work processes while maintaining the dayligh ng and sense of open-ness, human scale, and orienta on that characterized the original St. Elizabeths interiors;

• Prepare a current Program of Requirements and Space Planning with GSA and DHS with the goal of more effi cient use of available space in the ght constraints of the building footprint while respec ng the historic

preserva on goals.• Integra on of a contextually compa ble new structure to house loading

docks, trash removal and other service func ons required for the Center Building and other future adjacent new or adap ve reuse structures in accordance with the Master Plan.

ARCHITECTURAL APPROACHThe basic approach of this project is to support a modern offi ce work place environment in a rather challenging footprint spread over 3 to 5 fl oors. The architectural massing of the building, based on the needs of the previous hospital, is a long series of off set fl oor plates with a center corridor and pa ent rooms on either side. The building stretches approximately 1000 feet stepping both ver cally from 3 to 5 stories and horizontally allowing relief and interest where the building mass steps back giving prominence to the center por on of Building 1 with its characteris c notable central tower which will serve as the ceremonial entrance. The work places, offi ces and open work sta ons, will generally be located along a central corridor through the east-west wings of the building. These aisles or corridors have windows on axis at each end to provide relief and orienta on, retaining the original Kirkbride plan and fenestra on. The shorter north-south wings, where the building steps, are used for the transi on areas and the primary core elements of stairs, elevators, toilet rooms and MEP spaces. On the south end of Level 3 of Buildings 1 and 2 is a large open space which was used over me for various purposes – chapel, auditorium and gymnasium.

Historic Preserva onThe design is based on the applica on of the Secretary of the Interior Standards as codifi ed in 36 CFR 67 and in accordance with PBS-P100. Historic preserva on is paramount in the design of this project as indicated in the fi rst primary project goal “To respect architecturally signifi cant parts of the exis ng buildings, par cularly in the Zone 1 preserva on areas in Buildings 1 and 2”. Preserva on zones, as defi ned by GSA and documented in the 2010 HSR, refl ect a hierarchy of rela ve architectural importance and public visibility of a building’s exterior and interior spaces and are generally defi ned as:

• Zone 1 requires restora on - a process of accurately depic ng the form, features and character at a par cular period in me or “period of signifi cance”;

• Zone 2 requires rehabilita on - a process of making a compa ble use through repairs, altera ons and addi ons while preserving as many features as possible;

• Zone 3 requires renova on – a process of depic ng by new construc on the form and details of a structure or replica ng its appearance at specifi c period of me.

The “Period of Signifi cance” for this project, based on the HSR, is considered to be between 1856 and 1905 when most of the Center Building was originally constructed and served as the main administra ve and residen al center of St. Elizabeths Hospital. The exterior walls are considered as Zone 1 elements to be fully restored in place respec ng their original construc on and confi gura on and removing elements that were added a er the period of signifi cance. The only interior spaces that are to be considered Zone 1 are those that exist on the fi rst and second fl oors of Buildings 1 and 2 along the major north/south axis and on the second fl oor of Buildings 1 and 2 along the major east/west corridor, or “cruciform” area.

and then reconstruc on of the interior components of this building, the volumetrics in the rehabilita on and renova on Zones 2 & 3 will be reconstructed.

This project is an adap ve reuse of mid-19th century historic buildings for modern secure federal government offi ce space. The Center Building is the earliest and most signifi cant building of the Na onal Landmark campus. Given the loss of integrity of historic fabric, the design now includes:

• Restora on/rehabilita on of the historic façades - retaining as much of the façade fabric as possible, including window sash, especially in Buildings 1 and 2; with appropriate bracing and underpinning for new founda ons and reusing any face brick removed from façades where possible for elements to be rebuilt;

• Repair all areas of masonry, both brick and stone, that are structurally unsound and restore all exterior wall surfaces with complete repoin ng and cleaning;

• Replicate the visible metal roof construc on on the center area of Buildings 1 and 2 and the roofs of Buildings 6 and 8 which were iden fi ed as Character Defi ning Features in the HSR;

• Install new roofi ng systems on Buildings 3, 4 and 5 and the wings of Buildings 1 and 2;

• Reconstruct the porte cochere, and the bay window structure on the north side of Building 1 using as much original fabric as feasible and reconstruct in kind the wood porches on Building 8 to meet code;

• Reconstruct the masonry egress steps/stairs at several original loca ons, including metal handrails, to meet current code requirements;

• Provide a new entry at the south side of Building 2 at the Ground Level Level, under the historic south entry at Level 1 which will be rebuilt, that is sympathe c to the original building but is welcoming with a more contemporary design as the primary visitor and staff entrance;

• Removal of all exis ng interior elements including all fl oors, par ons and doors, roof and MEP (mechanical, electrical and plumbing) systems within the historic exterior walls in all buildings;

• Installa on of a new superstructure including fl oors, roof and all suppor ng architectural and MEP systems;

• Construct a simple new loading dock structure between Buildings 3 and 5 with interim cladding materials consistent with other materials used on the St. Elizabeths campus and appropriate massing respec ng its historic context;

• Reconstruc on of the primary layout and volumetrics of the public spaces and adjacent rooms on the fi rst and second fl oor main north/south corridors and the second fl oor east/west wings of Buildings 1 and 2 including the broad corridors and defi ning archways;

• Remove and reconstruct crenelated masonry parapets to meet current structural requirements with appropriate waterproofi ng systems for a complete weather- ght building envelope;

• Remove non-historic addi ons to the Center Building (primarily at buildings 3 and 5) retaining the historic wall fabric behind;

• Some character defi ning materials. principally in the Restora on Zone 1 will be repaired, removed for repair or replica on and incorporated into the design. Other Character Defi ning Features will be salvaged for GSA’s archival use. These items include wood trim, fi replace surrounds, extant millwork, interior doors, plaster moldings, metal grilles, and other similar Character Defi ning Features;

• Installa on of new interior systems in compliance with GSA PBS-P100 stan-dards for tenant fi t out and in coordina on with GSA and the tenant, the DHS.

• Meet or exceed the minimum “Performance Standards” as referenced from the PBS-P100.

The Design-Build Team will ensure that all ac vi es of design and construc on from major infrastructure to interior design elements do not adversely aff ect the historic fabric that is to be preserved. All repair, restora on and rehabilita on work will be done in accordance with the Secretary of the Interior’s Standards. Components that have been iden fi ed for restora on or removal and replica on and replacement will be carefully photographed and documented. Molds of all ornamental plaster trim and moldings will be done on-site and samples of moldings will be removed, cata-loged and stored as well as used as a resource for replica on.

The HSR iden fi es both the interior and exterior Character Defi ning Features that contribute to the historic character of the building; the tables on page 10 and 22 list these elements and the recommended treatment for each:

Exterior WallsThe strategy for incorpora ng por ons of the exis ng buildings including the historic mass masonry facades of the exis ng Center Building structure into the building enclosure for proposed DHS use as a modern offi ce building requires a careful balance of interven on and addi on as historic mass masonry wall assemblies typically lack the dedicated air, water and thermal barriers found in modern construc on to achieve the high performance expecta ons for enclosure performance commensurate with the an cipated use of the project building. The design proposes an enclosure moderniza on strategy that is commensurate with the design intent and achieves an op mal balance between performance, cost and constructability.

WindowsOver the nearly three-quarters of a mile of perimeter wall there are nearly 1300 wood windows, generally double-hung, that truly give character to and architecturally enrich the Center Building. Plywood boards were installed at all of the exterior windows in 2008 to protect the building un l the building could be renovated. The boards were removed late spring and the Design-Build Team performed an extensive study of all of the window components, the sash, frame, sills, and interior and exterior trim to evaluate the exis ng condi ons of all window fabric and to recommend the repairs and/or replacement needed.

Window reconstruction approach

The design intent is to use as many original components as possible including sash and exterior trim either refi nished or replicated, par cularly in Buildings 1 and 2. The survey indicated that most of the window sash, frames, sills (exterior), and interior trim throughout the building are in good condi on. 15% of the window sash will be repaired and reinstalled. The fully restored window sash will be located at the exterior of the perimeter walls of the Interior Restora on Zone 1 and Rehabilita on Zone 2 of Buildings 1 and 2. These areas comprise the north and south eleva ons of Buildings 1 and 2 and Floors 1 thru 2 and Floor 3 of the north eleva ons. The remaining sash will be replicated to match the light confi gura on with true divided lites. Approximately 85% of the frames, sills, and interior trim will be repaired. To the extent possible, all the window frames and sills will remain and be refi nished in place. Most of the interior window trim will be removed, refi nished and reinstalled. The exterior trim (brickmold) has more deteriora on then the interior components. Since the brickmold has a rela vely simple profi le and the survey indicated that approximately 40% of the brickmold is missing or in poor condi on, all new replicated brickmold will be installed. All of the glass panes will be replaced with new single pane clear glass, consistent with the appropriate historic light confi gura on as dictated by each window. All window components will be carefully removed, cataloged and stored for either repair or replica on based on the Secretary’s Standards and the specifi ed Historic Treatment Procedures and Maintenance of Wood Windows specifi ca on.

The window design concept includes new aluminum-framed “storm” windows with insulated glass that will be installed inboard of the restored (or replacement) historic wood windows. Based on the use of chilled beams as part of the HVAC system, the new storm windows will be fi xed (not operable) to limit the risk of condensa on due to the fl ow of condi oned interior air (e.g., warm humid air during cold winter weather) into the inters al space between storm and exis ng windows.

Entrances and Exits New egress points will be required at several loca ons around the building both at the G1/G2 Level in Buildings 5, 3 and 2 on the south side, and at Level 1 at Buildings 3, 1, 4, 6 and 8 on the north side. Of the 12 required egress loca ons, 7 will be in original loca ons and 5 will be new openings generally incorporated into exis ng window openings; the width of the original masonry openings will be maintained. New egress doors will be required at all loca ons and will need to meet all code requirements concerning doors, hardware, steps and railings which will be rebuilt to replicate the exis ng condi ons to the extent possible.

As stated above, due to necessary security restric ons, there will be only two exterior entry loca ons into the Center Building. The reconstructed North Entry or porte cochere will serve as the ceremonial entrance which will be used by the secretary, possibly other senior staff and any major important, diploma c visitors. The exterior of this entrance will be treated as historically accurate as possible taking design details from both the original porte cochere from 1874 and the rebuilt porte cochere from 1938, which is outside the date of historic signifi cance. An interior ramp will be provided for the transi on from the outside grade to Level 1 on the inside. New

ligh ng will be provided similar to what exis ng under the canopy during the period of signifi cance.

All staff and regular visitors to the Center Building will come in through the new South Entry doors. These doors will replace two exis ng (original) service doors that are at the G1 Level. The masonry openings will be maintained but the new entrances will be more modern to refl ect their new use and be more welcoming. The doors will be glass and a glass and steel canopy will be provided over each door for weather protec on; appropriate ligh ng and signage will also be provided at each door to iden fy this new entrance sequence. ADA accessibility will be accomplished naturally due to grade changes immediately to the south of the building thru a new entry court that will extend under the reconstructed historic metal stair that connects Level 1 with the sidewalk.

Roofi ngThe only roofs indicated as Character Defi ning Features in the HSR are on Buildings 6 and 8 which will be replicated in kind on those buildings. The roof of Building 8 is slate and the roof of Building 6 is standing seam metal; both roofs are sloped, hipped confi gura on. The exis ng sloped roofs on Building 3, 4 and 5 and the east and west wings of Buildings1 and 2 are not visible from the ground and will be replaced with a concrete roof deck which will be pitched to ver cal drains with a modern hot-rubberized asphalt membrane and insulated roof. The high roof over the center sec on of Buildings 1 and 2, although not iden fi ed as character defi ning, will be a standing seam metal roof similar to Building 6. This roof is highly visible from the ground.

Any structures (penthouses) placed on these roofs will be kept low, hidden by the tall parapets where possible, and will be clad in metal to match the visible roof components. The intent is to minimize the amount and size of any required roof structures or other apparatus on these roofs as the design is fi nalized. For addi onal informa on, refer to the Roof Plan located in Sec on 5 of this report.

At this point, the only other iden fi ed roo op equipment will be security cameras and Photovoltaic Panels (PV). These required cameras will be discreetly placed around the perimeter in loca ons recommended by DHS security but will be placed in manner within the crenella ons of the parapet to be as unobtrusive as possible. Currently, there is one array pf PV panels indicated on the fl at roof area on the west wing of Building 1 which will be confi gured to be low and not visible from the ground. GSA is also evalua ng a second array to be located in the future on the fl at roof area over the east wing of Building 1; it is not a presently in the design. Further, there will be a requirement by DHS for antennas for telecommunica ons and security which is not iden fi ed at this me. Once designed, these will be submi ed and reviewed separately.

Due to structural reasons, the parapets will be removed and rebuilt and ed into the roofi ng membrane for a complete weather- ght installa on. The crenellated parapets will be reinstalled in the same con nuous confi gura on as the original reusing the exis ng face brick with new precast concrete coping stones and fl ashing

as required. There are also two large exis ng masonry chimneys that will be removed and rebuilt in a similar manner.

Structural System Descrip onA new reinforced concrete structural frame will be constructed within the historic exterior masonry walls with fl oor framing consis ng of an 8 inch thick concrete fl at slab with 4 ¼” deep fl exural drop panels at interior columns. Ceiling construc on will conceal the underside of the concrete slabs. This system selec on results in a reduced dead load and seismic load, reducing the demand on the shear walls and founda on system. Reinforced concrete spandrel beams provided on all levels at the building perimeter have been detailed to sa sfy progressive collapse scenarios. The exterior wall connec on to the new concrete fl oor diaphragms will be detailed to provide out-of-plane support while accommoda ng ver cal and in-plane horizontal diff eren al movement between the wall and the new structural frame. While the removal of exis ng interior components and then the new construc on is being done, there will be con nuous movement and vibra on monitoring for the protec on of the historic masonry walls.

The eleva ons of the reconstructed fl oors will be in the original loca ons. These fl at concrete slabs have less structural depth than the original wood structure which will benefi t the new required ceiling plenums that will be required for various MEP infrastructure. The ceiling heights will be maximized in the Restora on Zone 1 areas to be as close to the original ceiling heights as possible.

The founda on system will be a reinforced concrete mat. A mat founda on was determined to be more construc ble than combined foo ngs or spread foo ngs with strap beams and was driven by excava on in the ght confi ned space between exterior walls. The building lateral system consists of reinforced concrete shear walls confi gured at core areas or adjacent to exterior walls. We recognize the importance of providing a laterally s ff structure to prevent damage to the historic masonry due to excessive inter-story dri .

Loading DockBased on the approved Master Plan, the Center Building will be the key component of a larger complex of buildings in the future serving as the headquarters for the DHS consis ng of some new and some addi onal adap ve reuse facili es. Programma cally, this complex requires loading dock and service func ons which is being proposed as a new structure that will be built at the intersec on of Buildings 3 and 5 at the southwest end of the original structure. Historically, Building 7 (Dawes) da ng from 1870 was situated at this loca on but was demolished in 1965. Although Dawes was 3 stories in height, this new loading dock structure will be one story, there is some historic precedent for a structure at this loca on.

There will be 3 berths – two loading docks and one trash compactor bay – with staging, recycling, storage, and security control areas inside. An addi onal loading dock berth is being considered by GSA but has not been included in the current plan; the massing of the structure has been designed to accommodate this added dock should it be included later. Trucks will approach from the east but will not enter

the building. The massing for this new structure will be kept as simple as possible and will be set back slightly to respect the two historic adjacent walls and ers of windows. Brick will be the prevalent material on the east wall with the actual bay doors in a recess placing the doors and their surrounding metal wall on a separate plane from the masonry walls with minimal overhead ligh ng provided within this recess for safety and security. A metal wall will con nue at the same plane as the doors and connect to the south wall of Building 3. It is an cipated that the south wall will be covered by a new structure in the future and this south wall would no longer be seen at that point. Consequently, a temporary cladding material will be used on the south wall; this material will be ver cal wood siding, a material already used in similar loca ons on the campus. Original buildings to the south of the Center Building referred to as “The Creamery” are located to the east of this loading dock will also screen a por on of this new addi on from the rest of the campus.

There are two fl at roof areas – one will be aligned with the sills of the Level 1 windows and a higher roof will exist at the southeast por on of the dock structure to accommodate the addi onal height required for truck clearance and loading dock opera ons. The low, single story por on is what will adjoin the original Center Building structure.

Concrete roadway paving to match the historic roadway will be extended to the loading dock entrances and protec ve curbs and bollards will also be required to protect the structure and pedestrians from truck movements. Refer to addi onal Loading Dock drawings and renderings in Sec on 5 of this report. Exterior Ligh ngThe design strategy for the exterior ligh ng is to replicate the fi xtures based on research and exis ng photographs da ng from 1889- 1905. None of the original exterior light fi xtures are extant. The north entry, a ceremonial entrance, has globe light fi xtures mounted to the rear posts of the Porte Cochere, similar to those visible in an 1889 photograph. Similar light fi xtures will be installed at the original south entrance (Level 1). Simpler and more modern globe fi xtures will be used at the new south entry court, the main entrance for DHS employees.

Ligh ng at the loading dock addi on will be LED wall sconces with full cutoff performance. The fi xture has a simple design with a slim profi le to minimize its appearance.

Exterior SignageA Campus-wide Wayfi nding and Signage Strategy for the St Elizabeths Campus was developed and applied to several buildings on Campus, including the US Coast Guard Headquarters. The goal of this previous eff ort was to create a logical and consistent approach to wayfi nding so that users may easily fi nd their way across the campus and within buildings of varying sizes, ages, and levels of complexity. The overarching principle is to provide a unifi ed aesthe c and promote the philosophy of “One DHS.”

The Campus-wide Wayfi nding Strategy includes a revised building numbering

EXTERIOR PAINT COLORS AND FINISHESsystem, unifi ed interior level nomenclature and consistent approach to interior room numbering and sequencing in all buildings. The strategy for the Center Building follows suit and builds upon these principles while providing for the unique requirements of the Center Building.

The exterior building signage is limited to 9” x 14” iden fi ca on sign located at each entrance and mounted to the face of the building. The design is iden cal to the previously approved and installed signs for use as Interim Campus Signage by the Commission on Fine Arts.

Paint Colors and FinishesAnalysis of the painted surfaces at the exterior and in the Restora on Zone of Buildings 1 and 2 is being done to determine the color pale e for the period of signifi cance. Analysis includes microscopic analysis of paint samples and review of previous studies and reports as well as historic photographs. Preliminary fi ndings of the exterior painted surfaces of the window frames and sash exterior sash indicate a pale yellow primer with a hunter green fi nish at the sash and a sanded brownstone fi nish at the frames. The exterior metal hoods have a sanded brownstone fi nish at the frames. The metal hoods and sills have a brownstone sanded fi nish. The fi nish treatment of the south entry door at Building 2 appears to be similar to the windows painted green at the door and sidelights and brownstone at the frame and surround. The wood porch at Building 8 appears to have been a grey color paint. The interior surfaces have a variety of fi nish treatment which includes polychrome paint schemes, stenciling, wallpaper (walls and ceilings), wood stains, and gilding.

Core AreasCore areas are defi ned as those areas which are permanent and serve basic func ons for all users on each fl oor. These are for ver cal circula on, stairs and elevators, major mechanical rooms and sha s, and toilet rooms and break rooms and the horizontal circula on areas connec ng these to the offi ce areas, corridors and lobbies. Also part of the core areas would be the primary entrances and security checkpoints. These areas are all important public areas that will receive a level of fi nish that, although respec ul of the historic character of the building, will be clean, contemporary and well lit refl ec ng their updated func ons.

The major “ceremonial” entrance to the Center Building is located at the north side on the 1st fl oor under the secretary’s offi ce. Although not an cipated to be extensively used, this is the historic main entrance to the Center Building and will be recreated to resemble the original including the lobby, ves bule, the drama c bay windows, porte cochere, and the driveway on the exterior. The major entrance serving the staff and visitors to this building is located at the south end of Buildings 1 and 2 with requisite security screening func ons. Except for the main north/south entrance corridor, the connec ng corridors to the various elevator banks and the few offi ce areas, most of the G1/G2 levels is fairly u litarian with fi nishes appropriate for those func ons. The basement fl oor or G1/G2 level contains mostly support areas such as major mechanical/electrical equipment rooms, custodial areas, O&M workshops and storage, as well as some offi ce space.

A new link to the now completed US Coast Guard Headquarters Building and the below grade Opera ons Center adjacent to the Center Building will be provided by a new interior stair and elevator from the west end of Building 5 down to a planned below grade connec on and will be used as access by DHS and USCG staff and will not be a public connec on. Refer to fl oor plans in Sec on 5 for addi onal informa on.

Interior ArchitectureThe Center Building is currently designed to accommodate several DHS Components in general offi ce and special use space including the Secretary’s Offi ce, an Execu ve Conference Center and Situa on Room. Flexibility is essen al in the design of this project as stated in the second primary project goal “To provide modern fl exible work places for tenant groups, complying with accessibility, life safety and security requirements;” while mee ng the project goal of preserving signifi cant historical elements of the building and providing an environmentally sustainable workplace.

In the original design, the main hospital building was posi oned to take advantage of the views of the river, the city, and the surrounding countryside. The length of the building was oriented east to west, with the majority of the pa ent rooms looking north over the river or south over the hospital’s farmland. The pa ent wards consisted of a central corridor fl anked by pa ent rooms, small dining rooms, and alcoves for common use. The central corridor was wide enough to serve as a common area as well, with rocking chairs lining the hall for pa ents to use. With the linear form of the building, the wards stepped back on either side of, and connected to, a central administra on wing.

Based on the HSR, the only interior spaces that are categorized as Zone 1 are on the fi rst and second fl oor in Buildings 1 and 2 at the heart of the Center Building. These spaces were the areas of public recep on, the offi ces of the superintendents and staff , the private residence of the superintendent in the 19th century and the primary east west corridor with adjacent pa ent rooms including the one occupied by Ezra Pound from 1947 to 1958.

The planning approach incorporated in the design follows these guiding principles. As the Hospital superintendents occupied the center of the building (Buildings 1 & 2) where the rooms were larger and more detailed with plaster moldings, wood trim and stenciled walls, it is well suited to accommodate the senior DHS staff and Special Use Areas. Areas located further from the “cruciform” area of Buildings 1 and 2 are aff orded greater privacy as well as more secure work environments. Component Groups will be located with ver cal adjacencies to accommodate work fl ow needs. The planning concept will also recall the arches that originally provided entrances to the day rooms or marked transi ons between wards.

In accordance with the guidelines for Preserva on Zone 1, the interior design approach rebuilds the historic spaces on the fi rst and second fl oors on the main north-south axis in Buildings 1 and 2, replica ng to the extent possible the volumetrics of the original rooms as well as incorpora ng the characteris c arches,

trim, woodwork and other details of those spaces. On Level 2, the pa ent rooms and dayrooms along the east-west will also be replicated based on the preserva on zone 1 plans in the HSR. The walls in these rebuilt areas will be at the same loca ons and thicknesses as the original walls with the door in the original loca ons as much as possible considering the updated code and structural requirements necessary for contemporary offi ce space. Doors, frames, and wood base would be replicated - some refurbished and reused - and cornices, crown moldings, arched openings would all be replicated and reinstalled in these rebuilt loca ons.

The narrow footprints of the building provide access to light and views to support employee wellbeing and the sustainable goals of the project. Daylight and views to the exterior environment contribute to reduced energy usage and to promo ng wayfi nding within the space. By drawing occupants through a space, daylight and views promote a sense of connec on to the outdoors, which contributes to enhanced produc vity. Posi oning corridors that terminate at the window line provides a focal point as well as a des na on and a direc onal cue.

While the original interiors were comprised of cellular spaces of more in mate scale, the newly opened ranges will aff ord a greater sense of space and light. Drawing upon this, and recalling the original intent of a healthful, naturalis c se ng, the aesthe cs of the interior spaces will be light, clean, and streamlined, evoking the simplicity of the historic hospital interiors and serving as a backdrop to views of the bucolic landscape.

LEED/Sustainable DesignSustainability is fundamental in the fi nal design of this project as indicated in the third primary project goal – “To incorporate environmentally sustainable design with the goal of achieving LEED Gold cer fi ca on”. There is a comprehensive LEED strategy for the project covering all aspects of the site, building, building systems and the interior. To that end, the base building and the interior layouts will be integrated to maximize access to daylight and views for the building occupants. A strong connec on to the outdoors will be maintained for the building occupants by providing access to light throughout the main circula on corridors.

Low profi le, removable photovoltaic (PV) panels will be provided only on fl at roofed areas and will be hidden behind the tall parapets. These will augment energy usage within the Center Building.

Energy consump on will be reduced in the building through the use of high effi ciency light fi xtures with individual occupant controls. The individual controls will provide each occupant with the ability to control their environment and reduces the overall electrical load for the building.

Addi onally, the environmental aspects of all materials and fi nishes have been taken into considera on in the development of the outline specifi ca ons. These guidelines will inform the selec on process, including the use of natural and rapidly renewable materials, products with recycled content, regional products which reduce energy

LANDSCAPE APPROACHSince the hospital’s establishment by Congress in 1852, the grounds surrounding the Center Building have been conceived, designed, and maintained as a therapeu c, ornamental landscape for the rehabilita on of the pa ents. The design intent for the current landscape is focused on the preserva on and rehabilita on of its Character Defi ning Features and is in accordance with the Master Plan and the overall campus Landscape Plan and the 2010 Cultural Landscape Report (CLR). The extent of the landscape design and approach in this Phase II design is to only replace or recreate landscape elements that are within the Limits of Disturbance (LOD) immediately around the Center Building as indicated on the Site Plan; the LOD is an irregular boundary depending on the various construc on ac vi es involved.

Further, during the construc on phase, the Design-Build Team will ensure the protec on of exis ng historic landscape features, including the brick circula on paths, the historic collec on of trees, and other landscape features, and ensure appropriate replacement or rehabilita on, if needed. Towards this goal, a Landscape Protec on Plan has been prepared that includes the following:

• Tree protec on during construc on and replacement;• Removal, storage, and reinstalla on of historic objects or materials to be

rehabilitated;• Guidelines regarding iden fi ca on and protec on of archeological resources

within the limits of construc on; and• Protec on of pris ne and mixed natural soils.

Landscape areas that have been disturbed or impacted by construc on ac vi es will be rehabilitated to create healthy, sustainable growing environments for exis ng and proposed trees and sod. Areas within the LOD that have been iden fi ed as containing exis ng poor soils will also be recommended for rehabilita on.

The reinstalla on of the stairs and brick paving surrounding the Center Building will be in conformance with the ADA and the ABAAS (Architectural Barriers Act Accessibility Standards). The landscape surrounding the building’s north entrance will be retained as a large, uninterrupted paved area surrounded by lawn and trees. Parking will be limited to offi cial vehicles at the east and west sides of this entrance. The south entrance will be the primary, day-to-day point of access and will be maintained as a paved entry court with some addi onal landscape features and sea ng areas.

This approach will preserve or rehabilitate the therapeu c and ornamental landscape that was used as a tool in the treatment of mental illness during the period of signifi cance, adap ng the no on of a therapeu c landscape to serve the modern working environment. The simplicity of the historic two-plane landscape, a “fl oor”

A-24




consis ng of large expanses of lawn shaped by gently curving pathways and drives, and a “ceiling” created by mature tree canopies, all framed by the mass of the Center Building will be retained. The use of historic materials and pa erns will be repeated in the treatment of new or replaced circula on features, including brick paving in a herringbone pa ern and scored concrete paving. The plan ng plan and tree selec on concept is based on surviving trees species, and informa on from the CLR list of species historically used on the campus. This historic precedent of plant species at St. Elizabeths is refl ected in the design intent of the therapeu c landscape as it was developed and selec on was based on the CLR species list and also surviving tree species on site.

All of the historic landscape architecture work will be accomplished in compliance with the Na onal Capital Planning Commission’s Environmental and Historic Preserva on Policies and Procedures, as amended in 2004, as well as the Secretary of the Interior’s Standards and the Guidelines for Cultural Landscape Treatment and in accordance with the 2010 Landscape Preserva on and Management Plan.

The CLR also iden fi es the Landscape Character Defi ning Features that contribute to the historic character of the building; the Table below list these elements and the

CIVIL ENGINEERINGThe primary design intent of the site is to restore vehicular and pedestrian access; provide proper drainage and upgrade the u lity service to the Center Building while preserving the historical context and landscape character of the site.

Site U lity SystemsNew u li es are proposed to connect the Center Building to the Campus wide u li es that were constructed with an earlier phase (Phase 1 U li es Implementa on). This will provide new and reliable u lity service to all buildings on campus. Generally the u lity upgrades consist of new sanitary sewer; storm sewer and potable water systems along with addi onal water to improve fi re hydrant coverage. The Center Building will also be connected to the central u li es duct bank providing a new supply of both hot and chilled water service to the Center Building. Addi onally, new electric, communica on and security services will be extended to the Center Building from campus-wide upgrades implemented with the previously approved Phase 1 U li es Implementa on Phase.

U lity Integra on The u lity systems provided for this project are generally a con nua on of the u lity network that was implemented with the previous construc on phase (Phase 1 U lity Implementa on Phase) including the extension of hot and chilled water from the Central Plant and the Campus wide electric and communica ons network.

Site SustainabilityThe site storm water system is being integrated into the Campus wide storm water management program which was established to comply with EISA Sec on 438 to provide more sustainable storm drainage prac ces and is in accordance with the Master Plan. The design of the storm water system will incorporate LEED design prac ces.

EXISTING CONDITIONS AFFECTEDThe March 2, 2012, Final Master Plan Amendment Final Environmental Impact Statement (“FEIS”) and the 2012 Record of Decision (“ROD”) for the Amended Master Plan provided a full assessment of environmental resource impacts aff ected throughout the campus and this site and should be referenced as addi onal informa on related to exis ng condi ons aff ected. The historic landscape impacts and contribu ng buildings features treatment matrices were further reviewed and discussed during Sec on 106 Consulta on mee ngs. These addi onal informa on sources are exhibits to the MOA and are also available at h p://www.stelizabethsdevelopment.com/documentcenter.

BUILDING POPULATIONThe offi ce and special use spaces in the Center Building are planned to accommodate a total 900 staff . It is an cipated that 10 to 15% amount of staff will be on travel, telecommu ng or working remotely at any given me.

MASTER PLANThe project has been infl uenced by NCPC approved 2009 Master Plan, the NCPC approved 2012 Amended Master Plan, the HSRs and a number of historic preserva on reports and guidelines and was further developed with input from the Consul ng Par es Sec on 106 consulta on process. The design solu ons depicted in this submission have been accepted by the Consul ng Par es through consulta on. As a result, the design is stronger. Improvements have focused on overall adherence to the St. Elizabeths master plan and further minimizing adverse eff ects to the site. The design solu ons herein have no devia ons from and are in compliance with the Amended Master Plan.

The following describes the rela onship of the Master Plan to the elements of the Center Building design:

• Building Use, Heights and Massing: The Center Building design is in alignment with the St. Elizabeths Amended Master Plan in terms of density, building use, height and massing.

• Landscape Revegeta on: The landscaping solu on will promote the con nuity of the topographical bowl of the District of Columbia. The plan ng strategies are consistent with the historic preserva on plans of restoring the arboretum style plan ng of trees that existed on the Plateau in 1937 as well as restoring the ecological health of the forest areas on the slopes.

• Site Access and Circula on: Primary staff access to the site will be from Gates 4 and 1. Gate 4 is an access point that was created from the new access road parallel Interstate 295 along the western edge of the site. Ceremonial access to the building will be available from Mar n Luther King Boulevard and through the upper plateau of the West Campus at Gate 1.

• Building Materials: The materials used for the Center Building Design will match or be similar to the elements found on St. Elizabeths Campus site: brick, sandstone, slate, and metal.

• Security: Security Elements of the design are in compliance with the November 10, 2008 Security Master Plan and are in compliance with the Interagency Security Commi ee (ISC) standards for a Level 5 facility.

• Construc on Access: Construc on access for the Center Building Design-Build Project shall occur from the exis ng Gate 1.

A-28




• Restora ve Stormwater Management: A series of restora ve Stormwater Management ac vi es is underway for the en re west campus. These comprehensive remedia on ac vi es will stabilize decades of neglect and fi x unresolved stormwater run-off /capacity challenges. In addi on, the restora ve stormwater management and erosion/sediment control ac vi es are necessary to contain the impact of required site clearing and demoli on ac vi es.

GOVERNMENT COORDINATIONThis project was coordinated with the District of Columbia and associated DC agencies including the DC Mayor’s Offi ce in conjunc on with consul ng par es and community mee ngs. In November 2015, NCPC’s Coordina ng Commi ee will review this project for fi nal coordina on with DC agencies. The Coordina ng Commi ee consists of GSA, WMATA, Na onal Park Service, DC Offi ce of Planning, DC Public Works, DC Water and Sewer, and DC Housing and Community Development.

COMMUNITY PARTICIPATION GSA has con nued its Community Outreach related to the St. Elizabeths West Campus design eff orts with invita ons to the ANCs and Ward 8 Business Council to the Sec on 106 Consulta on mee ngs and par cipa on in a variety of community mee ngs as requested.

Throughout the past few years, GSA has a ended mul ple ANC mee ngs, made community presenta ons and conducted business opportunity forums to con nue to involve the community in the development of the DHS Headquarters Consolida on at St. Elizabeths. The community has provided GSA with three key themes associated with this development:

• Economic Development: The community wants to promote the use of local services to aid in the economic development of this area to ensure the cam-pus is an integrated part of the community and not a walled off compound without connec vity to the local business community. There is a strong desire for community individuals and businesses to become involved in the economic development and benefi ts to the Ward 8 community for both the long and short term through:

• Local Businesses providing goods, food and support/amenity services to the campus development and occupancy in both the short and long-term

• Construc on/Employment Opportuni es• Longer term Employment Opportuni es with DHS

GSA con nues to work with the community on these issues by conduc ng outreach with the Ward 8 Business Council to assist small businesses with learning more about opportuni es associated with the project; loca ng a jobs trailer on the campus to assist with the job employment opportuni es; and conduc ng pre-appren ceship programs in the community.

A-29




• Traffi c Conges on: The community is concerned about the worsening of traffi c condi ons in the local area surrounding St. Elizabeths and Mar n Luther King, Jr. Ave. As part of the Master Plan and the Transporta on Man-agement Plan, GSA has planned for a majority of the transporta on to reach the site via the new Access Road and to aid in minimizing transporta on impacts along MLK.
