NeffR Snapshot

1.4.1 BASIS OF VALIDATION

Construct a General Instruction Building. The primary facility will provide spaces for general instruction classrooms, lecture halls and collaboration space, administrative space with private and open offices, an auditorium, lab space, conference rooms, reception areas, a library and mock courtroom, an arms vault, showers and bathrooms, lactation rooms, copy rooms, staff break rooms, departmental storage, vending areas and a cafe, as well as freight and passenger elevators. Cybersecurity measures, Electronic Security Systems (PACS & IDS) installation, Energy Measurement and Control System (EMCS) connection, building information systems, and fire alarm and fire protection systems will be included.

Supporting facilities include utility connections (water, sanitary sewer, electrical), storm drainage, sidewalks, curbs and gutters, landscaping, and site improvements. Heating will be provided by district heat, and air conditioning will be provided by a chiller located in Building 604.

Comprehensive building and furnishings related interior design services are required. This project will be designed for accessibility and usability by individuals with disabilities.

Utility connections are required to privatized electric distribution, water, and wastewater systems. The Army intends to have the respective Utilities Privatization System Owners, American Water and City Light & Power (CLP) make and own the necessary connections up to the facility service disconnect or other defined point of demarcation. Facilities will be designed to a minimum life of 40 years in accordance with DoD's Unified Facilities Criteria (UFC 1-200-02) including energy efficiencies, building envelope and integrated building systems performance.

The U.S. Military Academy (USMA), at West Point, is implementing an academic infrastructure and capabilities upgrade program. The keystone of this program is the Academic Building Upgrade Program (ABUP), a holistic program involving the renovation of key buildings to correct a substantial deficit in general instructional space. This Thayer Hall Renovation project is part of this program. This project will consolidate key programs in one facility and ensures that academic buildings meet both the current and future needs of the USMA's academic departments. By upgrading and consolidating key programs into a central location within the main campus, the academy aims to foster a more cohesive academic environment while addressing its instructional space deficit. The centralization of programs will reduce the physical fragmentation of departments and encourage more cross-disciplinary collaboration.

This approach aligns with modern educational trends, where academic institutions are moving towards flexible, multi-purpose spaces that encourage interaction and innovation. Bringing key programs together in adequately sized spaces will not only optimize the use of space but also create an atmosphere where students and faculty from different disciplines can engage in meaningful collaboration, enhancing the learning experience. Thayer Hall will support an occupant load of 2,980 people. The project's primary goal is to reduce the instructional space deficit, which, if left unresolved, would continue to impair the academy's ability to support its students effectively. By upgrading the instructional facilities, the academy seeks to align itself with contemporary educational standards, which prioritize collaborative learning, cross-disciplinary interaction, and active engagement between students and faculty.

Additionally, the current building lacks the critical utilities and technology infrastructure required to maintain pace with the rapidly changing academic environment. The facility lacks natural lighting and acoustic separation, has ongoing issues with water filtration and inadequate air flow through the building and has had recent electrical equipment challenges resulting in

READY TO ADVERTISE PDR

THAYER HALL RENOVATION

diminished electrical capacity for the facility. The outdated IT infrastructure in the building is insufficient to meet the demand load of today's technology driven learning environment.

Required assessments have been made for supporting facilities and the project is not in a 100-year floodplain in-accordance-with Executive Order 11988. This project has been coordinated with the installation physical security plan, and all physical security measures are included. All required antiterrorism protection measures are included. Alternative methods of meeting this requirement have been explored during project development. This project is the only feasible option to meet the requirement. The Deputy Assistant Secretary of the Army (Installations, Housing and Partnerships) certifies that this project has been considered for joint use potential. The facility will be available for use by other components.

Sustainable principles, to include life cycle cost effective practices, will be integrated into the design, development and construction of the project and will follow the guidance detailed in the Army Sustainable Design and Development Policy - complying with applicable laws and executive orders.

3. Brief summary of the COS Position:

COS concurs with this waiver for an additional 51,767 square feet over the GIB Standard, as well as the inclusion of non-standard Collaboration space and a Café space.

The square footage increase reflects:

a) The need for a higher net-to-gross planning factor (35,600 SF), READY TO ADVERTISE PDR

THAYER HALL RENOVATION

b) Additional faculty space (21,715 SF),

c) The Café (1,434), and

d) The inclusion of “Cadet Collaborative Space” (a 6,982 SF reduction from the standard allocation for a ‘Resource Center’ which it replaces).

Detailed analysis is provided below:

3a Net to Gross (NTG) Factor increase - NTG factors in post-secondary academic buildings typically range from 1.47 to 1.67 for new construction, reflected in the GIB Army Standard. The net-to-gross factor in the ‘proof of concept’ for this project is 1.81. The higher NTG factor is justified due to:

a. Building is a renovation encumbered with the construction constraints of an incompatible original building use (Riding Hall for equestrian instruction) which carries inherent inefficiencies in layout.

b. Building gross square footage is encumbered with ~2’-4” thick walls and approximately 30 projecting bastions along it’s approximately 1,500 linear footage of exterior wall, while typical wall construction for new construction is approximately 1’-4”. Exterior compatibility is a requirement of the NHLD designation and SHPO. This additional wall thickness on all four floors accounts for ~6,500 square feet.

c. The excessive footprint of the building (~580’ x 140’) necessitates a ‘racecourse’-type primary circulation layout which adds considerably to the circulation component of the NTG factor. This additional circulation accounts for nearly 18,000 square feet.

d. Due to the enormous footprint of the building, additional exiting (in the form of exit stair, passageways, discharge, etc.) are required beyond what is typical for a multi-story building, to address ‘path of travel’ code limitations. In accordance with egress codes, approximately 10 exit stairs are anticipated, and fire rated corridors will be approximately 8 feet wide.

Based on these reasons, the COS believes the NTG factor increase – from 1.67 to 1.81 - is justified. This NTG delta is approximately 35,600 square feet.

COS Position: Concur

3b Office area – This Army Standard allocates an overall square footage of 155 net square feet per FTE staff for office and supporting spaces; this space is intended to account for the entire office area ‘suite’ (i.e. NOT just the individual walled offices). USMA is requesting 213 NSF per FTE staff (based on 79,685 net square feet and 374 FTE) when including the supporting spaces.

This request is slightly higher than the square footage allotment at a typical research university. However, due to the heavy inclusion of group work in the cadet’s curriculum, faculty will need to accommodate groups of students at a time, which requires conference/counseling, tutor space, and reception/control/waiting space.

Within the offices, most faculty are assigned 160 square feet. There are also important differences between USMA and typical Army schools in terms of level/rank and expertise of the USMA faculty. USMA faculty are the equivalent of O6/GS-15 and above and are leaders in their specialized field with PhD or equivalent and conduct research as well as teach and partner with peer institutions and host academic events (conferences, guest lectures, review

READY TO ADVERTISE PDR

THAYER HALL RENOVATION

boards, hosting Distinguished Visitors, etc.). Several private colleges and universities are moving toward a range of 140 NASF to 160 NASF for a typical faculty office. Cornell, M.I.T., and Stanford all are using 160 NASF as the size of an office for new construction.

COS Position: Concur

3c Cadet Collaboration Space – These provide space for cadets to study and interact in an academic environment when not in class. Provision of this space is consistent with pedagogic trends in collegiate academic space planning as assignments become increasingly interdisciplinary and collaborative pursuant with the goal of augmenting peer learning and interaction. Provision of this space in academic buildings creates comfortable study space for students to be productive between classes and is efficiently integrated with the circulation system of the building generally as 8-PN meeting spaces.

Although not included in the GIB Army Standard, Student collaboration spaces most nearly reflect the “Resource Center” insofar as being a non-classroom study space. USMA’s collaborative space square footage request of 11,198 NSF is within what the Resource Center’s allocation would be for the same student load (based on 3,030 FTE students) of

18,180 NSF.

COS Position: Concur

3d Student Café – The GIB Army Standard allows 4 ASF per FTE student for a Student Break area under the ‘General Use’ occupancy category. In this project, in lieu of student break rooms, USMA proposes a café with seating which, at 1,434 square feet, is within the 12,120 square feet that would otherwise be allotted for break areas. Given the use of collaborative spaces (11,198 square feet) for group work between formal class time, COS concurs that the combination/synergy of these two space types – café and collaboration - fulfills the requirement for break area.

2. PARAMETRIC DESIGN ANALYSIS

2.1 SITE DEVELOPMENT / CIVIL

This project is located in or near a floodplain.

2.1.1 GENERAL SITE DESCRIPTION

Approximately one half of the River Courts, which will be utilized for staging and storage, is located within the 100-year floodplain, however the project does not anticipate impacts to the floodplain extents.

The Thayer Hall Building 601 is not located in or near a floodplain.

The project site is located at the United States Military Academy (USMA) in West Point, New York. The existing Building, Thayer Hall, is located east of Cullum Road, south of the West Point Club, north of the Central Power Plant (CPP), and west of the Caufield Boathouse and River Courts. Jefferson Road and Brewerton Road are pedestrian ways that lead perpendicular to the northern and southern ends of the building, respectively, and Jefferson Road can accommodate vehicular traffic. The access drive around the perimeter of Thayer Hall is commonly referred to as the “Moat”. The Moat is at an elevation approximately 45 feet below Cullum Road and ties into Williams Road at the southwest corner of Thayer Hall. The existing Building and surrounding area are 100% impervious. Please see Appendix 4 for the Building Location Map.

The River Courts, D Lot parking lot, and Salvage Storage Area within the Transfer Station will be utilized for contractor staging and storage. The River Courts are 100% pervious, currently occupied by grassed athletic fields, and are approximately 100 feet below the elevation of the Moat. D Lot and the Salvage Storage Area are 100% impervious, consisting of asphalt paved parking lots. D Lot is located west of Thayer Hall along Stony Lonesome Road, and the Transfer Station is located along Route 293.

2.1.2 SITE DEVELOPMENT

The objective of this project is to construct a new general instruction Building. A majority of the existing building will be demolished, specific areas of the existing building will remain in place, existing utilities will be relocated or maintained, and subsequently, the proposed general instruction Building will be constructed. Utility services to the existing Building will be interrupted during construction. Coordination will be done with West Point and the responsible utility companies to minimize interruptions to other buildings to remain.

The design also involves coordination with various disciplines. See the following for items related to Site Development / Civil:

The following is a summary of site development improvements:

Establishing of Contractor Staging and Storage Areas

The Contractor will utilize River Courts, D Lot and the Transfer Station as the staging and storage areas.

The exact uses and configurations of these areas will be determined by the Contractor. However, it is anticipated that D Lot will be utilized for materials storage and that the River Courts will be utilized for the contractor’s office facility, contractor parking, construction equipment, material storage, and construction trailers. The Transfer Station will be utilized as a Salvage Storage Area for storage of architectural elements to be preserved. For storage of any architectural material, the materials shall be kept covered and out of the elements, such as rain and snow, to the maximum extent feasible. See Appendix 4 for more information.

Approximately one half of the River Courts is located within the 100-year floodplain, however the project does not anticipate impacts to the floodplain extents. If the Contractor desires to use the area within the floodplain, they will be responsible for any required permitting, Providing vehicular access at southwest corner of existing Building and Maintaining access to the Moat around the Building throughout Construction

The southwest corner is the primary point of access to the Moat from Williams Road.

It is paramount to maintain access for vehicles and construction equipment during demolition and construction.

Additionally, the existing utilities will be maintained and protected throughout construction. The responsible utility providers will need to have access to those utilities which are located within the Moat.

Establishing Protocols for Road Closures

The Contractor is responsible for all necessary traffic control and related permitting during construction. See Appendix 4 for more information.

Maintaining Pedestrian Flow

See Appendix 4 for more information.

Relocating and Maintaining Site Utilities

utilities on-site. During demolition and construction, portions of existing utilities will be relocated and maintained in place. See Section 2.2 for more information.

Placing Erosion and Sediment Control Measures

Erosion and sediment control measures to be utilized for the site include, but are not limited to, inlet protection, silt fence, concrete washout, dust control, and a stabilized construction entrance.

Demolition of Existing Building

To facilitate vehicular access for construction vehicles in the Moat, the Annex of the existing Building is anticipated to be demolished first. Prior to demolition of the Annex, vehicles will be able to access the Moat via the archway under Cullum Road that leads into the Moat. The only limitation with this path is the height of the existing archway, 10 feet high, which will limit the size of vehicle that can access the site through this point.

After the Annex is demolished, vehicles will be able to access the building through the corridor between Cullum Road and the portion of the existing building to remain;

this will facilitate larger vehicles with greater height clearance.

As demolition progresses, demolition material will be hauled off-site. See Truck Access Plan in plan set for the haul route to be used by vehicles.

See Section 2.2 for utilities to be maintained and protected during demolition, and utilities to be relocated during construction.

See Section 2.4 for information regarding bracing of the existing features needed during construction.

Demolition of Architectural Features to be Salvaged for Reuse

See Section 2.3 for more information.

Demolition of Existing Pedestrian Bridges

Extent of removal of existing pedestrian bridges to be determined by other disciplines. See Sections 2.3 “Architectural” and 2.4 “Structural”.

Construction of Utility Corridor

A utility corridor will be placed within the Building footprint. The utility corridor will include steam and condensate and chilled water. Other utilities may be included as well. West Point Directorate of Public Works (DPW) will have access to the utility corridor, once construction is complete.

Construction of Proposed Building

The proposed Building will be constructed. Grading will be designed so runoff will drain away from the proposed Building and towards existing and proposed drainage appurtenances.

See Section 2.1.5 for more information regarding Landscaping and Section 2.3 for more information regarding Architectural.

In the post-development condition, the Moat will be designed to maintain current vehicular access.

Development and connection of concrete walks across the western length of proposed Building

In the area between the proposed Building and Cullum Road, concrete walks will be constructed to allow pedestrian access to the northern and southern ends of the proposed Building from Cullum Road.

Below the concrete walks along the western length of the proposed Building, which is also the location of the existing Moat, a proposed vehicle service access tunnel will be provided to allow permitted vehicles access along the west and north elevations.

The tunnel will accommodate a pickup truck, with approximate dimensions of 12’-0” wide by 15’-0 to 20’-0 high. An area along the northern end of the building will be used for vehicle turnarounds.

Existing utilities that will be housed within the vehicle service access tunnel, currently in the existing Moat, will be maintained. Some may need to be relocated to avoid conflicts with the proposed building. The tunnel will be gated at each end of the tunnel, one at the southwest corner of the building and one at the northern end of the building.

See Section 2.1.5 for more information regarding Landscaping and Section 2.3 for more information regarding Architectural.

Development of concrete walks across the eastern length of proposed Building

A pedestrian access walk is proposed along the eastern edge of the proposed Building.

See Section 2.1.5 for more information regarding Landscaping and Section 2.3 for more information regarding Architectural

See Appendix 4 for additional information provided in Project Sketches.

2.1.3 PAVEMENT (ROADS, PARKINGS, WALKS)

No roadway design or parking areas are proposed as a result of the construction for this project. Contractor is responsible for any repairs for damages caused to Academy infrastructure (existing roadways, curbing or sidewalks) during construction activities. Any disturbed infrastructure shall be restored to the design standard.

Sidewalks shall be designed pursuant to Federal standards or Academy standards; whichever is more stringent.

2.1.4 STORM DRAINAGE

Pursuant to discussions with stakeholders held during the Design Charette in February 2026, it was confirmed that the project will not lead to an increase in impervious area. Therefore, stormwater detention is not required at Thayer Hall.

Stone laydown will be utilized at the staging and storage area at the River Courts and will temporarily replace existing site soils during construction conditions.

In the existing condition, roof leaders from Thayer Hall drain to an existing pipe north of Thayer Hall. A portion of Cullum Road drains to the existing pipe system within the Moat, which discharges to this existing pipe north of Thayer Hall. The pipe north of Thayer Hall daylights at the edge of the steep slope near the northeast corner of Thayer Hall, leading to the River Courts. Thereafter, the runoff enters a pipe system which discharges directly to the Hudson River.

THAYER HALL RENOVATION

Runoff from the Annex and Cullum Road drains towards the existing drainage system within Williams Road. This system drains south down Williams Road, ultimately discharging directly to the Hudson River.

In the post-developed condition, Cullum Road drainage patterns will be maintained. Thayer Hall roof runoff will be directed to the existing pipe north of Thayer Hall.

A State Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater Discharges from Construction Activity (GP 0-25-001) will be required for this project.

2.1.5 LANDSCAPING

The development of site/landscape concepts for this project has been guided by a set of core planning and design considerations that ensure the adjacent site functions safely, inclusively, and efficiently. Key factors shaping the emerging site/landscape concepts include strengthening academy connections to support cohesive circulation, integrating traffic calming strategies to enhance cadet safety, prioritizing universal accessibility, and creating opportunities for outdoor breakout spaces that enrich daily academy learning. Across all design decisions, long-term maintenance has been carefully considered to promote durability, sustainability, and ease of care for the Academy.

ACADEMY CONNECTIONS

The Brewerton Pedestrian Bridge (Brewerton Road) and Jefferson Road function as the primary east-west circulation axes of the academy, each terminating at Thayer Hall (see Figure 2.1-1 Building Location). Emphasizing these key terminal points within the site/landscape concepts help to reinforce intuitive wayfinding and a strong sense of place as cadets circulate from exterior to interior.

In advance of the February 2026 Design Charrette, the project team developed three (3) design concepts (Courses of Action). Each Course of Action (COA) took varying approaches to these axial academy connections leading to Thayer Hall, as well as the north-south connection along the west façade of Thayer Hall and Cullum Road.

Initial Design Discovery Brewerton Pedestrian Bridge Connection | During the initial design discovery, the team determined that, to maintain universal accessibility, modifications to Brewerton Bridge would be needed to account for approximately 4-1/2 FT of grade change between the existing bridge elevation and the proposed Level 4 elevation of the building design. Each of the initial COAs proposed removing the bridge in its entirety and replacing it with an expanded pedestrian bridge, each varying in size. Vehicular clearance was reviewed to ensure proposed modifications met or improved existing clearance requirements, approximately 17 FT.

Cullum Road: North-South Connection | Each initial COA explored a different design concept to cadet circulation, moving from north to south (and vice versa). The concepts included circulation between building entries at the same floor elevations (Level 4 to Level 4) and circulation between varying floor elevations (south (Level 3) to north (Level 4)). The latter concept lent itself to an improved and safer circulation route for cadets by providing a space for cadets to jog off Cullum Road.

Preferred Course of Action Following the Design Charrette, the project team consolidated the initial COAs into one

(1) plan that incorporated feedback received during the charrette and design check-in meetings and addressed the continued development of the architectural floor plans.

The latest COA was presented during a Friday, May 8th, design check-in meeting and is

the Preferred COA moving forward. See Appendix 4 – Project Sketches, for overall and enlarged plans.

Brewerton Pedestrian Bridge Connection | In a continued effort to emphasize universal accessibility across the site, the Preferred COA replaces Brewerton Bridge in its entirety. The improved pedestrian bridge follows a similar alignment to the existing as it crossed over Cullum Road. The eastern edge of the bridge connects to an elevated deck, at Level 4, allowing for circulation in and out of Thayer Hall. To further enhance circulation, a convenience stair is provided to allow for movement between Level 4 and Level 3.

Cullum Road: North-South Connection | The safety of cadet circulation along Cullum Road is a serious concern to the academy. The Preferred COA establishes a fully accessible circulation path that allows for movement from Jefferson Plaza to the existing Cullum Road sidewalk (north of Mahan Hall).

This route has been sized to account for cadets to jog side-by-side in a safe, off-street, condition and to accommodate snow removal equipment.

TRAFFIC CALMING MEASURES AT JEFFERSON PLAZA & CULLUM ROAD

Cullum Road serves as the primary vehicular route through the east side of the academy, intersecting with Jefferson Road at the north side of Thayer Hall. During the February 2026 Design Charrette, the project team observed and discussed cadet safety concerns at this intersection. The existing intersection provides limited protection to cadets crossing Cullum Road.

To improve the safety of the intersection, the Preferred COA illustrates a raised pedestrian crossing along Cullum Road between Jefferson Road and the existing Jefferson Hall Plaza.

Raising Cullum Road by approximately 6-IN creates a continuous, plaza-like surface that functions as a shared-street environment, allowing cadets to move more seamlessly between Jefferson Road and the proposed north plaza at Thayer Hall. In these conditions, drivers intuitively reduce their speeds as traditional vehicular cues, such as curbs, defined lanes, and grade separation, are minimized. Paving patterns, distinctive materials, and pedestrian-scaled design elements further reinforce that this is a pedestrian priority space. See Appendix 4 – Project Sketches, for overall and enlarged plans.

OUTDOOR BREAKOUT SPACES

Integrating outdoor breakout / collaboration spaces was discussed during the February 2026 Design Charrette. Incorporating these spaces into the concept is essential in providing flexible, resilient spaces that can support ceremonial and instructional activities, and encourage informal interactions that build camaraderie among cadets.

The Preferred COA provides several collaboration spaces along both the north and southwest of Thayer Hall. These spaces are designed with flexibility using adaptable surface materials and movable site furnishings to accommodate varying program needs. See Appendix 4 – Project Sketches, for overall and enlarged plans.

See Section 2.3.3 Architectural for information on roof terraces designed to serve as additional outdoor breakout spaces.

PLANT SELECTION

Planting will consist of a variety of ornamental trees, shrubs, perennials, and groundcovers.

Designated planting beds will be supplemented with a topdressing of mulch (organic or inert still to be determined). Selecting species that are well-adapted to a shifting climate, are salt

tolerant, and have low demands for supplemental watering or fertilizing is critical to reducing long-term landscape maintenance. Plant selections will prioritize clear sightlines, standoff distances, and the avoidance of dense or concealing plantings near buildings to conform to Anti-Terrorism/Force Protection (ATFP) requirements within the 33 FT stand-off requirement per the Design Basis Threat (DBT).

OVERALL MAINTENANCE

Long-term grounds maintenance is a key consideration of the Preferred COA. Maintenance plays a key role in preserving the long-term functionality, safety, and appearance of the site.

Selection of surface paving material, plant materials, and miscellaneous site features will be selected thoughtfully with these points in mind. The Preferred COA is designed to accommodate snow removal equipment, with all sidewalks a minimum of 6 FT wide.

Landscape beds have been placed to serve a dual purpose of aesthetics during warm season months and for snow piling during colder season months.

2.3 ARCHITECTURAL

2.3.1 FACILITY DESCRIPTION

BUILDING FUNCTIONALITY, PLANNING AND DESIGN PRINCIPLES

The existing four-story Thayer Hall is approximately 350,000 square feet. Its longest dimension (~615 feet including the southern towers) extends north / south. The east facade faces the Hudson River; the west facade faces Cullum Road and the Garrison. Its narrowest dimension (~146 feet at the roof level) faces to the north and south.

Thayer Hall’s primary mission is to support the education of approximately 2,980 West Point cadets through classrooms, departmental administrative offices, specialty spaces, and amenity areas. The building is designed to remain adaptable to evolving technologies through an integrated approach to space planning, building systems, and furniture solutions.

Program organization is guided by four key planning principles: flexibility, collaboration, access to daylight, and connectivity. Building entrances converge at a multi-story rally point that functions as a central gathering space and supports a variety of uses. Strong visual and physical connections to this space are prioritized throughout the building. Primary circulation routes are efficient and clearly legible, with collaboration zones strategically located along main and secondary pathways to support cadet and faculty safety.

Phase 01 and Design Charrette

Three preliminary design concept options (COAs - Course of Action) were presented during the February 2026 Design Charrette. Each The COAs incorporated feedback from the December 2025 Phase 01 Charrette regarding initial programming discussions, and the retention of select portions of the historic building and envelope.

The COAs were named to identify a primary characteristic or organizational principal unique to each concept. The Charrette COAs were named as follows: “Order/ Clarity”, “Hierarchy / Balance”, and “Elegance / Order”.

* Preliminary block and stack studies evaluated the distribution of the space program within a multi-story massing concept. Informed by end-user feedback, initial analyses, and a refined program of requirements, three alternative courses of action were developed following the Design Charrette.

* Exterior design and massing were studied through physical models and renderings. All COA’s expanded the existing footprint to the west and increased the number of stories to seven.

Feedback was received regarding the preferred architectural style, building presence, identity, and projected strength. The extent of existing walls and architectural details to remain, including those to be removed and salvaged for reinstallation were refined.

Elements from two of the concepts, “Hierarchy / Balance” and “Elegance / Order”, were selected for further development.

COA Development

THAYER HALL RENOVATION

The project team incorporated feedback and analysis from the Design Charrette to refine the floor plans, concepts, and exterior design. Three alternative COAs were developed: “Cadets Take Stairs”, Activate the Edge”, and “Views for All” and presented at the March 27, 2026, Design Meeting.

* Cadets Take Stairs- A central circulation spine connects program components both vertically and horizontally, clearly separating classrooms and departmental spaces, while also serving as a daylighting strategy. Classrooms are organized along the western façade, while departments are located along the eastern façade. Amenity areas are positioned adjacent to the primary building entry, maximizing views to the river.

* Activate the Edge- A primary circulation corridor along the western façade provides access to daylight and…
