On a prominent street corner in the Upper East Side, a property manager sought to reposition a ground floor space to attract new commercial and retail tenants. The project scope included a complete gut renovation and re-design of the 9,100 sq. ft. space, including the basement and entire retail storefront. EDG provided structural analysis, spatial studies, tenant-specific layouts, and full architectural and structural design services.
The existing building was extremely fortified, enclosing invaluable real estate and separating the interior from the street. EDG analyzed the load-bearing structures, discovering opportunities to reduce walls and open the floor up to the outside. Working within tight structural constraints, EDG enhanced customer experience by relocating stairs, introducing expansive windows, and optimizing floor layouts. The team supported the owner’s ongoing search for tenants, providing several renderings on quick turnaround, customized to individual commercial and retail prospects.
The re-imagined space at the intersection of Madison Avenue and East 80th Street draws pedestrians into an immersive environment that blends retail sales with a lifestyle embodying its products. With a distinct sensitivity to material design, brass and brown fiber cement finishes respond to the surrounding residential context. A new basement skylight and warm wood finishes create an airy, contemporary ambiance. Making the most of the existing configuration, the new commercial space breaks down barriers between interior and exterior, passerby and customer.
Construction Cost: $1.5 Million
When EDG learned that the deteriorating 574 Fifth Avenue faced demolition, the team was inspired to preserve the intricate 1940’s ornamentation. While typical processes to restore historic facades are expensive and time-consuming – and therefore usually not feasible - EDG sought modern, highly effective techniques to keep NYC treasures like 574 Fifth Avenue around.
EDG experimented with additive manufacturing methods to apply 3D printing to real-world applications. The team tested out different design technologies, printers, mold thicknesses, and materials. After several iterations, the team discovered an optimal formula and process. The team proto-typed and diagrammed the full assembly, using 3D printed plastic forms inlaid with laser cut wire mesh and stirrups to reinforce the cast.
Using 3D printing for façade and ornamentation molds, EDG not only pioneered a process for modern façade experimentation and ornamentation but also a way to extend the life of existing architectural gems. By producing digital archives of façade elements and using easily-accessible, affordable printing materials, the replacement of parts can happen on-site and with a dramatically shortened lead time. Breaking apart from standard pre-cast forms, this new technique allows designers and property owners to celebrate the details of historic buildings for generations to come. The design also allows for the addition of additional stories behind the original façade, expanding space vertically and maximizing real estate value.
This Brooklyn project is a re-development of an existing three-story building with a commercial ground floor in Greenpoint, Brooklyn. Working with a developer, the scope included a gut renovation and addition to transform the structure into an attractive co-living space. EDG provided zoning, financial models, help in fundraising through private equity, development analysis, planning, and full architectural and structural design for the 9,000 sq. ft. mixed-use building.
The objective was two-fold: create a “singular address” as a Brooklyn focal point and design a kit of parts adaptable for future developments. Given the building’s prominent corner location adjacent to McCarren Park, Bond and EDG aimed to refresh the outdated townhouse and maximize the buildable area. The team gutted existing spaces and added a fourth story, doubling the residential area. Leveraging in-house zoning and code expertise, EDG and Bond produced highly efficient floorplans, with a rentable area only 8% below gross area. The communal living units and amenities are economical and modular to support Bond’s long-term strategy.
The four-story revitalization features a diversity of social spaces, including a retail base with outdoor seating, interior courtyard, rooftop, and basement recreation area. The design opens the building to the neighborhood, playing to local elements while introducing a signature aesthetic. Paying homage to its eclectic and heterogenous orbit of an industrial warehouse legacy, Victorian fronts, and new residential projects, the building plays up this spirit with a dynamic façade with changes character from day to nighttime. Individual living spaces are elegant, comfortable retreats from the city. Carefully considering the desires of the target demographic, the color palette and material finishes evoke a cool sensibility balancing energy with calm. The innovative mixed-use development creates a community of shared value and sets a new standard for co-living.
The Briarwood Apartments property extends block-to-block and avenue-to-avenue, holding 280 units in two nearly identical buildings. The existing buildings were situated off-center on the lot, creating an awkward 60-ft. rear yard. Site challenges included complicated zoning issues, a sloping site, parking constraints, as well as the impact of an addition on the existing structure. After seeing our success on another project in Queens, the client retained us to do an investigation of the site’s development potential. Two other architects had previously assessed the property and determined they could only build a small, 30-unit building on the corner of the lot.
With every project, we know there is a puzzle to solve and that anything is possible. We carefully navigate the Zoning and Building Code, which is often misunderstood, and involve the Department of Buildings in our analysis to ensure compliance. For this project, we obtained three “pre-considerations” from the Department of Buildings to clarify zoning issues that could potentially affect the feasibility of the project later on.
Where other consultants saw only a large backyard and an unsightly view of the back of a building, EDG envisioned a completely new structure. With our expertise in the Zoning and Building Code, we designed a compliant addition that spanned over 600 feet in length. With two new building segments, our thorough investigation enabled the addition of 180 units to the property.
The EDG team initially performed a property analysis for this entire city block on 106th Street, from street-to-street and avenue-to-avenue, between Madison and Fifth Avenues. The goal of the project was to unlock the maximum value of the property by utilizing the maximum allowable floor area, repurposing existing space, and increase parking on the site. As a result, our work includes designing approximately 170,000 sq.ft. in total new floor area and renovating 48,000 sq.ft. as part of over 10 projects throughout the development site.
The owner previously retained two other consultants who determined only 20,000 sq.ft. of the remaining FAR could be used. We revisited the original zoning analysis performed on the existing site and found multiple locations available to construct approximately 170,000 sq.ft. of gross floor area. Our work also included navigating the Harlem-East Harlem Special Purpose District, as well as recent rezonings and the original zoning at construction. We looked at the site holistically, carefully examining the existing building's operations, while considering the seamless integration of the proposed buildings. We also considered structural considerations for all proposed work.
Our high-level understanding of zoning and building design experience gives us the advantage of having a complete picture of a development site. For this project, we navigated a large number of zoning and code considerations, including subdividing the site. We de-risked dozens of potential issues on an incredibly complex site to make the development possible. As a result of our initial work finding ways to capture the full underutilized FAR, we are currently designing the reprogramming of 48,000 sq.ft. of ground floor spaces, including: retail, commercial and community facility space; a 60-car parking garage expansion; additional commercial/community facility space; the consolidation of lobbies to recapture floor area; as well as the design of a new 19-story residential tower.
The project was for the property assessment and site planning of four zoning lots with existing buildings on the waterfront in Long Island City, Queens. The subject property extends street-to-street, encompassing two corners, and is an Inclusionary Housing site. Massing and 3D renderings were prepared. We are currently in schematic design for the new building.
The size of the site gave us some flexibility, however the existing buildings on the site created constraints. We needed to be sure that our proposed lot merger didn’t create a new non-conformance with yards or distances between buildings. The property also had a portion of the site with a Landmarks designation, and although we were able to work the design around the boundaries, we worked with Landmarks to ensure compliance.
Ultimately, we determined that the site had approximately 200,000 sq. ft. available and usable, far greater than the owner’s original estimate of 60,000 sq. ft., provided by their previous architect. Yards and courts were carefully navigated to maximize the use of floor area on the site while providing maximum and minimum building dimensions that lend well to the future design of the apartments. The site is in a flood zone, so residential occupancy is not permitted at ground floor, and the site is not on a retail corridor, so we dug in deeper for ground floor use. We utilized the existing occupancy at the ground floor, looking to lower the use from existing manufacturing to public parking, which will be of great benefit with the new ferry opening nearby.
The Fire Island Pines Pavilion bar and nightclub is an icon of Fire Island Pines, one of New York's favorite summertime getaways since the 1950s. In 2011, a devastating fire destroyed the original Pavilion, and EDG was brought on to serve as the structural engineer for the new 8,000-sq.ft. structure. EDG worked alongside award-winning architectural designer HWKN who crafted a dramatic design to honor the legendary site.
It includes a terrace, outdoor bar and lounge, indoor bar, and dance floor with bleachers at each end, as well as a gym and three retail spaces. Although the venue regularly serves as a club and hosts parties at night, the space is also used for performances, as an art gallery, and even a wedding chapel in the daytime. To celebrate the Pines’ beloved beach culture, the design incorporates exposed-wood surfaces and structural materials throughout, creating the perfect beach backdrop for any event.
For this Tribeca Penthouse project, we worked with award-winning architectural designer, Steve Blatz. We performed the structural design for the gut renovation of a 6,000-square-foot apartment and a 5,000-square-foot addition of vegetative green roof space and landscaped roof decks. We investigated the existing structure for the remediation of construction defects and managed legal work associated with the penthouse addition and structural support of the green roof and roof decks.
After finding evidence of issues with the existing construction, we performed probes to identify the defects. Had we waited to investigate the structure, like many consultants do, we would have needed to completely redesign the project during construction, halting work and increasing the budget. This project included extensive interior alterations, where structural work involved a new interior courtyard, interior column removals, and reinforcement of existing structural elements. The roof decks were required to be independently supported so that loading was not transferred to the cast iron frame.
All of the construction defects were handled without having to demolish any of the existing structure, which saved hundreds of thousands of dollars. All new work was carefully designed so the existing cast iron framing was not used as structural support, and apartments below were not affected. The contractor for the project was impressed by EDG’s communication with them, as well as our focus on constructability, and has since recommended us on several projects.
The Victoria’s Secret retail store in Herald Square recently expanded their ground floor space by 30,000 sq. ft., taking over the entire basement and cellar floor as well as the fourth and fifth floors of the building. As part of the alteration, we designed the renovation to the existing floors, portions of the sidewalk vault space, and the fourth and fifth floors for conversion to storage, requiring a floor load increase. The project also included a sky bridge in the building’s courtyard on the fourth and fifth floors, which required façade alterations.
Prior to EDG’s involvement, another firm designed a repair to the 100-year-old basement for a new retail space. After reviewing the report and plans, we conducted our own assessment, performing probes and a historical review of the structure, to determine the Building Code construction requirements when the building was constructed in 1909. Prior to even probing the structure, we determined that it had significant additional capacity based on its original design.
Probes confirmed our expectations; the basement was constructed of very heavy steel and exhibited minimal deterioration. Savings over the original estimates were about 1 million dollars and the work was completed in a fraction of the time, so the store could open earlier than anticipated. Our assessment of the existing construction conditions also allowed for a larger sky bridge for the same cost. This project reflects our commitment to ensuring our clients always receive the most value for their money.
The Milford Properties consist of a cluster of high-rise apartments, nestled in the heart of Battery Park. Constructed in the 1980s, these brick façade buildings complement the vibrant Hudson River waterfront and offer the ultimate in luxury living. Several Milford properties totaling over 1,000 units, including 99 Battery, 200 Rector, and 380 Rector were in need of façade repair. Milford Management engaged the EDG team to perform façade inspections, prepare repair documentation, perform construction administration, and conduct Local Law 11 reporting.
As part of the New York City Local Law 11 façade inspection, EDG surveyed, inspected, and designed building-specific façade repairs for each high-rise structure, ranging from 25 to 44 stories tall. The maintenance and repair campaigns consisted of scaffold drops, coordinated rigging, identification of all deleterious conditions, and preparing plans and construction documents for contractor bidding and repair work. EDG managed and observed all work, from start through completion of each project.
Due to the waterfront location, EDG assessed leaking and replaced the existing sealant with modern materials to prevent water infiltration. Working hand-in-hand with Milford Management staff, our team provided recommendations for repair, construction schedules, and cost estimates for budgeting. EDG worked diligently to address concerns and streamline the project with the client and contractor, handling weather-related challenges and on-site conditions with minimal disruption to the tenants. Projects were completed on time and under budget.

North Shore Towers comprises three of the tallest structures in Queens. Rising well above the surrounding area, each tower is 34 floors and constructed on the highest point in the county. EDG was retained by North Shore Towers to conduct Local Law 11 inspections and reporting for the 110-acre community complex. Constructed in the 1970’s, the team discovered that all 2,352 balconies were in need of repair and set forth documenting conditions for restoration.
EDG initiated the large-scale project with comprehensive due diligence, reviewing all available records and site conditions. Running the project efficiently to reduce costs and limit disruption to tenants, the team emphasized tight coordination with team members, contractors, DOB, and North Shore Towers. Each of the towers required 69 scaffold drops and 2-3 drops per location, totaling approximately 500 drops. The restoration includes repairs to concrete balconies, eyebrows, minor brickwork, and railing installation. Due to the sheer size of the undertaking, it was critical to maintain precise tracking of documentation, DOB filings, and material quantities – all of which EDG managed through advanced on-site technology.
The comprehensive restorations improved safety and saved on long-term costs for the luxury community complex.
Vice President of Greenthal Property Sales, Linda D. Rappaport remarked, “As the main broker for the North Shore Towers and a resident myself, I’m grateful for the work EDG did on the building façades. Throughout the project, even when they were working on my own high-rise terrace, the team was conscientious, timely, and professional. The restored balconies and facades look great and better represent the ‘luxury community’ essence of our residences.”

The Bowstring tower is a building design feat of material innovation and cross-disciplinary prowess. Inspired by the tensile strength found in bridge suspension cables used in structural engineering, the EDG team sought a new way to capitalize on their strength.
Applying structural engineering techniques, the tower introduces tension cords into high-rise vertical construction. Cables on all four vertices connect the topmost and bottommost concrete corners of the building.
By exploring new methods of designing and constructing large towers, EDG’s team extracted more space efficiency by maximizing floor areas, introducing a new design aesthetic, and innovating at the intersections of engineering and architecture. The proposed mixed-use residential, office, and commercial program stands as an icon in the skyline and a herald for architectural invention.
The Generator is an urban waterfront tower development, rising out of the ground where a former power plant stood for three-quarters of a century. Nestled amongst a cluster of industrial buildings, the tower aims to create a unique office building that meets – and greatly exceeds – 21st-century energy goals.
EDG focused on careful analysis, location, and efficient design that leverages solar, wind, and hydrological energy sources. The elevated promontory the building sits on acts as an elevated parkland which anticipates water surges and mitigates wave action, allowing for hydrological filtration and phytoremediation. The team lifted the building body and office program 210 ft. above ground in anticipation for rising sea levels and to reveal the giant helical wind turbine. The sophisticated double skin is designed for modulated fresh air, with perimeter ERVs that manage intake and exhaust air much like gills. Interior spaces are heated and cooled via a radiant in-floor and ceiling hydronic system, using energy captured by the geothermal field in the park below. Further cooling is regulated by a deep-water cooling system drawn up into the tower’s heat exchangers.
The Generator, with its multitude of sustainable energy strategies, is beyond net zero. The dynamic tower capitalizes on natural, renewable elements of air, sun, and water from all around. It maximizes views of Manhattan and Brooklyn while referencing its surrounds in its own design. Intentionally playing upon the neighboring bridges, the Generator harks upon its past while looking optimistically towards the future.
At the heart of Manhattan’s east side, the 36-story residential tower in Kips Bay offers unbeatable comfort and convenience. Interested in maximizing the value of existing spaces, real estate agency Kibel engaged EDG on a residential renovation of approximately 20,000 sq. ft. of the property’s shared roof and plaza areas. EDG’s architectural and engineering team collaborated on extensive planning, design, and construction administration to reinvigorate the aesthetics and functionality at 300 East 34th Street.
EDG navigated complicated building codes, conducted structural analysis, and explored possibilities to re-purpose existing components to achieve a cohesive, welcoming design. On the ground plaza, the team introduced carefully considered geometry and materials to existing site elements. On the roof, the team retrofit a previously inaccessible space by extending elevators, transforming mechanical rooms into amenity space, and reviewing the impact of increased loading of the existing roof.
With meticulously planned architectural and structural moves, EDG unlocked the potential of the residential tower’s community spaces. The building’s 300+ residents now return home through a distinct landmark piazza, where lively congregation fosters a rich civic space. The plan enhances accessibility, visibility, and capacity – while maximizing retail potential and developing a signature design on the ground plane. Thirty-six floors above, residents enjoy an exquisitely curated 360° panorama of Manhattan’s skyline, accompanied by a pristine pool, lush gardens and pergolas.

Growing VANS’ “Off-The-Wall” legacy, the leader in footwear and skateboarding sought to open a new store in Herald Square. Located less than 100 yards away from Manhattan’s busiest intersection, the existing four-story, 100+ year old structure required an extensive gut renovation. RGLA engaged EDG for structural design services, including the creation of 20-ft. high ceilings above the retail space, a new elevator installation rising from the basement through fourth floor, a new stairwell installation connecting the first and second floor, and a refreshed storefront conveying the VANS brand.
The existing structure was a complicated amalgam of previous renovation campaigns, which became an unwieldy patchwork of century-old building materials and techniques mixed with modern construction. With deep knowledge of both historic and modern construction, EDG analyzed the conditions and employed best practices to bring the project vision to fruition. To create the double-height ceilings, EDG removed the third floor in its entirety – a task which required the removal of an exterior masonry wall and load transfer toto a new steel support structure hidden within the walls and ceiling of the second floor below.
Given the location's prominence, it was imperative to open the retail space prior to Black Friday. By engaging modern structural analysis software, EDG was able to immediately update designs based on architectural revisions and in-field conditions. Providing constant onsite representation throughout the tight construction schedule, the EDG team was responsive to all unexpected conditions and updates. From initial concept through close out, the entire project was completed in less than six months, with the store opening before Thanksgiving. The exciting new space transformed a complex existing structure into an immersive customer experience center, expanding VANS’ street culture influence in the heart of Manhattan.
This project involved the creation of a high-end retail space on the high-end street - Madison Avenue. We performed an
extensive gut renovation, removing three floors of the structure, and replacing only two, reconfiguring egress to provide
more efficient exits, while opening up the floor plan to better suit retail operations, and installing a new elevator. While
handling the architectural design, renderings, structural engineering, and filings, we needed to navigate historical code,
Landmarks, as well as new building code requirements due to the alterations.
The result was a first-floor level with the ground (prior ground floor was sunken, making retail access challenging) and second floor located in a position that provided expansive heights on these two floors 100 ft. deep. The design needed to be contextual in color palette, unaggressive in its stature, and inviting in nature.
The finished ground floor, with ceiling heights of 17 ft. clear - nearly a perfect square height to width, with a storefront appearing as a single panel of glass, creates the feeling of a “windowless” shopping experience between you and products inside. The design concept transcends the brand, with any retailer projecting their product, here. With barely a hint of the physical separation, the store can be referenced from the street and now the street becomes an extension of the store.
Having seen what EDG could do on other projects on the property, the client retained EDG to review the development potential of the site. A 13-story building currently exists on the site. The building is the shape of an E with a large yard, which forms the shape of a C, not visible from the street.
This project is near the top of the list of complicated projects, which EDG has grown to specialize in. EDG found that with improvement bonuses, up to 235,589 sq. ft. could be added to the site. This resulted in an additional 25 stories, for a total tower height of 37 stories. The new structure partially penetrates the three existing floors of retail and two cellars, requiring extensive coordination. In addition, a new separate entrance for the tower lobby needed to be provided.
Floor area bonuses require special permits, tied to relocation of subway entrances and other improvements, which needed to be assessed. Egress for the new tower was also carefully navigated through the existing egress stair towers. For wind and seismic loading, EDG designed an exterior structural support system which minimized the impact on the interior of the existing structure. Upon completion of our work, EDG worked with the client and CMs to prepare preliminary cost estimates.
This three-story building (Lenox Avenue Addition) with a cellar is located in Harlem, NY. The construction is brick and cast iron, supported on pile foundations. EDG performed a feasibility study for the addition of one to three stories on the existing structure as well as the replacement of the existing structure with a new building. EDG's work included planning, architectural design, structural engineering, geotechnical engineering and cost-estimating. Previously, EDG was the architects, engineers and project managers for the 9,000-sq.ft. Red Rooster restaurant and event hall, which span two levels of the building.
Because the building was occupied during design, EDG took the least invasive approach for the foundation test pits and probes. EDG looked to configure the addition so that it was supported by the vertical and lateral supports of the existing building structure. Designing the addition to this 80-year-old structure required a deep understanding of historical construction types.
Once EDG determined that reinforcement was required, EDG designed the addition so only one line of columns required reinforcement and so the ground floor restaurant could continue to operate during construction. EDG then outlined the requirements for the addition to determine costs for project feasibility.
EDG was hired to repair the 3rd, 4th and roof levels of the South Broadway Garage, located in White Plains, NY. EDG designed the restoration of the precast structure, including the façade. The previous owner had neglected the structure, leaving the three levels in extreme disrepair. In some areas, water would pour in from the ceiling, obstructing vehicular traffic.
By surveying and probing the structure, classifying work into critical and non-critical categories, and reviewing long-term preventative maintenance opportunities, EDG determined potential vs. actual costs and offered repair options through value engineering. EDG also provided the owner with design options for the future parking expansion.
The project was carefully phased, so critical areas were addressed first. We successfully evaluated alternatives to add value to the structure, including the potential expansion of the parking garage. Note: During the course of the project, the garage was acquired and demolished by the City of White Plains.
Concordia College is a private liberal arts school located in Bronxville. The school struggled for a few years to provide additional parking on their campus, because local authorities were concerned about potential traffic and environmental impacts. The client approached EDG to design parking layout options that would maximize the number of new spaces while minimizing impacts on neighboring properties and landscape. With EDG's designs, Concordia was able to meet with the Mayor and local authorities to discuss potential impacts and gauge political support for the project before navigating the approvals process with the local planning board.
EDG surveyed the site to determine existing conditions, opportunities and constraints. Work included review of vehicular ingress, egress and internal traffic flow, as well as preparation of schematic plans to demonstrate parking capacity for various layout options. EDG prepared detailed plans for the chosen layout, including tree replacement, lighting, and stormwater design calculations.
EDG increased the parking capacity of the site by over 30% with less than a 20% increase in impervious areas and ultimately provided a more cost-effective solution with a greater parking capacity than offered by other consultants. EDG also helped the client manage the political side of the approvals process.
Design of a new 12-story, mixed-use building, approximately 140,000 sq. ft. in Queens, NY. The apartment building includes a community facility and parking garage below. EDG provided engineering design, specifications, and construction observation services for the project.
Lack of communication is often the cause of failure on projects, so EDG put a lot of focus on it here. One example of this is engaging the construction manager as early as possible for a constructability review to confirm that the project design is compatible with the means and methods of the intended construction, as well as to discuss the feasibility of all details. EDG also review potential complications that EDG has experienced on past projects, as they tend to repeat themselves.
EDG always does our part to improve the project team’s communication because it saves our clients significant amounts of time and money. EDG's efforts prevent costly redesigns which are often incurred in merging design and construction requirements.
Located on the Hudson River, Pier 40 Parking Deck is the largest in the city. It includes an enormous recreation center, acres of field space, approximately 2,200 long-term parking spaces (the largest parking facility in Manhattan), and the offices of Hudson River Park Trust, who operate Hudson River Park and 36 piers. The scope of work for EDG included the assessment of the existing deck conditions and design of the rehabilitation of the 40+ year old pier, including the complete replacement of the top slab deck and waterproofing.
Given the large square footage of the complex, every detail can have a significant cost impact, so EDG looked carefully at the key cost variables. Many repair options were explored to obtain the optimal solution. The client required that the roof deck be made watertight for years to come, so EDG carefully evaluated leading waterproofing systems to find one that fit the needs of existing and future conditions. As the largest revenue generator for the Hudson River Park Trust, continued operation during construction was extremely important and phasing had to be carefully planned.
EDG prepared cost estimates for the work at every stage of design. The project not only came in just below our budget estimate, but below the contracted construction cost. The success of the first phase of the project was a team effort made by all parties, including Trust’s team and the contractor. EDG initially set out to understand everything about the existing conditions in the scope of work. This high level of due diligence paid off, and no design changes were required. All phases of design work were completed early or on-time, which was essential for the pier to continue serving both the community and the Trust’s operations.
In 2010, 2015, and 2017, the New York City Housing Authority issued a bid for the restoration design of their developments’
façades and roofs. EDG was one of ten firms selected to receive a five-year contract for the design of the envelope work
for a portfolio of over 2,600 buildings. Our work includes preparing Local Law 11 façade condition reports for Cycles 6, 7,
and 8 for more than 250 of NYCHA’s buildings. EDG is one of two firms pioneering a new contract structure combining
Local Law 11 inspections and facade repairs, which include design, specification, and construction administration.
Due diligence is always our first step, as we carefully review all available records and visit the sites to determine conditions
that affect our work. Having a clear picture of prior work on the developments allowed us to properly plan our approach.
Each Cycle requires meticulous planning, coordination, and approvals with NYCHA, NYC Department of Buildings, and
external contractors. By incorporating the latest technology and software, the EDG team optimized workflows and
minimized the manpower necessary to complete a higher volume of buildings.
Our office has not missed any of the numerous deadlines and aggressive timelines set by the Housing Authority. By
streamlining internal work processes, the EDG team delivers higher quality deliverables with increased rates of approval,
ultimately saving NYCHA both time and money. Our work with NYCHA helps ensure the safety of the occupants and the
longevity of the buildings.
The H-bridge Rehabilitation is a two-way vehicle and pedestrian bridge that crosses over the Metro North Hudson Line in Tarrytown, NY. It is nearly half a mile of elevated roadway deck and sidewalk. The steel members, concrete roadway, expansion joints, sidewalks and drains required rehabilitation. Extensive deterioration was found at steel columns and girders that required shoring and immediate repair.
EDG quickly opened up communication with the Village of Tarrytown and the Metro North Railroad to obtain a history of reports and construction to the bridge and roadway. They were kept informed of the status of all work to prevent any delays later in the project. EDG's knowledge of material science and concrete and steel deterioration played a key role. Severely deteriorated steel was immediately identified and testing was performed on all steel showing evidence of deterioration.
In consideration of budget expenses, EDG assess priority phasing on nearly all of EDG's restoration projects. With an experienced eye, EDG identifies immediate repairs, short-term repairs, and any long-term maintenance work required. Ultimately, over six million dollars of restoration work will be required, which will be performed over several years to work within the budget of the Village.
EDG NYC was invited to submit a proposal for the design of a new, state-of-the-art crime lab with support spaces for the District Attorney’s Office. EDG's work included planning, design, specification, cost-estimating, filing, bidding and construction administration services for the 21,000-square-foot project.
EDG’s project management division is well known for facilitating projects requiring specialty design. For this project, EDG brought in McClaren Wilson & Lawrie, Inc., an architecture and planning firm specializing in laboratory design. EDG provided seamless communication and handled the standard complications, while navigating the filing process.
Drawing from dozens of previous lab designs, MWL created an effective space that met all the goals of the District Attorney’s Office and achieved certification with the American Society of Crime Laboratory Directors. EDG's ability to find and work with the right specialists allows EDG to take on any project requiring extensive experience and avoid time-consuming learning curves.
Penn Plaza's eight-level underground parking garage with slab-on-steel framing services the 57-story high-rise building above it and the surrounding area, which includes Madison Square Garden. EDG was hired to conduct extensive concrete slab and steel beam repair and replacement, as well as waterproofing membrane repair and installation throughout.
To keep the garage in operation during construction, EDG carefully phased repair areas and split them up into 14 sections. The waterproofing membrane application was performed in seven phases.
The 33-story, 609-unit Lincoln Plaza apartment building occupies half of a city block with approximately 300,000 sq. ft. of façade. EDG was retained for emergency inspections at 30 Lincoln Plaza when previous repairs at the concrete eyebrows began to fail. The subsequent scope of work included façade inspections, preparation of repair documents, construction administration, and Local Law 11 reporting.
Emergency conditions required that EDG mobilize and assess the concerns immediately, but a complicated geometry proved challenging for inspections. One of the major obstacles of facade restoration is assessing the entire facade with only limited access. As a result, EDG does much of our work from the ground, using high-powered, image-stabilizing binoculars and telescope equipment. This technique provides accuracy, eliminating the need to perform scaffold drops on all facades prior to construction. EDG's “hands-on” inspections are performed later to get a better idea of deterioration. During construction, EDG had up-close access to the entire facade area.
The ability to mobilize a full team quickly allowed EDG to stabilize the concerns with minimal disruption to tenants. EDG phased subsequent repair work, in order of importance, around the needs of the client.
This 500-unit condominium includes a plaza and parking lot above a parking garage. The garage was neglected by the previous owner and left in extreme disrepair and needed Rego Park Garage Rehabilitation. EDG’s work included parking garage restoration, plaza repairs and redesign, parking lot repairs, parking lot extension and façade repairs.
Initially brought in by a tenant who was on the opposing side of the ownership, the client quickly learned that EDG had a solid understanding of the work. EDG were hired by both parties to jointly handle the project. They were shocked by the estimate provided by their former consultant, so we looked to determine all the unknowns, reducing potential costs to actual costs, and began value-engineering repair options.
With minimal assessment and two probes, EDG significantly reduced contingencies and worked to evaluate alternatives that would add value to the building, including expanding parking as part of the repairs. EDG ultimately completed more work for 25% of the cost the client had been provided by their former consultant. EDG also carefully phased the work so the worst areas were handled first. The parking lot expansion provided significant value to the client.
Located in Lower Manhattan, this 23-story, Cass Gilbert landmark was gut renovated, converting the historic office tower into a luxury apartment building. As part of the West Street renovation, EDG performed architectural design and structural engineering services for the enlargement of an existing amenity space within the central portion of the building.
Renovating a historic building is very challenging, given many unknown conditions. EDG's client also requested a modern design which complemented the building’s original aesthetic. To meet these challenges, EDG opened up masonry walls on two sides of the space and cut back existing non-structural piers, creating new connections to adjacent rooms. EDG then designed a new ceiling system and lighting layout to unify all of the spaces visually. This architectural strategy allowed for an integrated design, balancing both modern and historic elements.
Using an adjacent one-bedroom apartment, the renovation increased the indoor amenity space by more than 700 sq. ft. At the same time, EDG's design revitalized the 500-sq.ft. courtyard and created a more visual and physical connection between all indoor and outdoor common areas. The result is an expansive, contemporary amenity space, including a fitness center, yoga studio, private dining / event space, lounges, meeting spaces and landscaped terrace.
This Beekman Avenue historical building occupies the full footprint of a three-acre lot with an interior courtyard of over an acre. The five-story building includes approximately 250,000 sq. ft. of residential housing with commercial space on the ground floor. Due to the extensive deterioration of the brick and decorative stone elements, 3,000 linear feet of sidewalk shed was erected at its perimeter and walkways to perform the work. The restoration scope included brick and lintel repair, as well as parapet and roof replacement.
EDG conducted thorough inspections and assessed the full scope of all required building envelope repairs. We prepared overall construction cost estimates and phasing plans in order for the client to budget and plan. During the construction administration phase, EDG assisted with bidding out the work to contractors and performed all of the quality control inspections.
Due to the massive footprint and presence of the property, phasing of the project was crucial. The critical areas requiring repair were completed first, so the adjacent sidewalk bridging could be removed, ensuring minimal impact on both the commercial and residential tenants. The client also wished to restore the original building aesthetic, which was achieved by replacing the deteriorated ornamental stones and motifs with new cast-stone-veneer decorative elements.
This Fort Lee project included the restoration of a 120,000-sq.ft. parking garage structure and a resident plaza level with a pool, servicing a 300-unit apartment building. The structure required extensive repairs throughout, including slabs, steel beams and girder reinforcement to restore the structural capacity.
EDG was hired as design engineers and architects after initial cost estimates from less experienced firms, showed excess work and an over-estimated construction cost estimate. EDG was responsible for the concrete slab and steel framing rehabilitation, plaza level waterproofing (80,000 sq. ft. with topping slab construction), green roof installation, pool deck alterations, and ADA accessibility.
The repair work was completed on schedule and at 35% of the cost estimate provided by other consultants. EDG planned the work to be performed in eight phases so the garage could remain operational during construction. The 13,800-sq.ft. green roof transformed the previously unutilized plaza area into a beautifully landscaped amenity for building residents.
The Helmsley Hotels range from 16 to 40 stories with exterior façade construction varying from brick and stone masonry to glass curtain wall. For several Helmsley Buildings, prior to their recent sale, we have performed façade condition reports (including Local Law 11 reporting), design services for façade repairs, parking garage repairs below the hotel, plaza repairs, roof repairs, as well as interior architectural alterations.
As a result of the New York City Local Law 11 façade inspections, EDG designed extensive façade repairs to the structures as part of a maintenance program developed for the Helmsley Organization. For the associated façade repairs, EDG identified scaffold locations, coordinated riggers, identified all required repair locations and prepared all construction documents for contractors to place bids.
EDG worked directly with the Helmsley’s management staff, providing cost estimates and schedules to the client for budgeting purposes. With careful planning, all work was completed on time and within EDG's estimated cost budget range. For all of the projects, we effectively managed the process, including the filing of the work with the Department of Buildings. We start filings very early in the process and understand the potential pitfalls of the Department of Buildings, allowing us to shorten the average filing period considerably.
EDG provides engineering and architectural services for many parking operators, including Icon Parking, Garage Management, Champion, Imperial and Edison Parking. Icon Parking alone has over 200 parking facilities in New York City, with over 5.5 million sq. ft. of space. More than most, they understand economies of scale in construction and turn to EDG to design cost-effective repairs, renovations, and new facilities.
Our services provided to parking operators include condition surveys and concrete testing, condition evaluation, construction documents for repairs, cost estimating, bidding, construction administration, and site observation. The garages have varying types of construction, such as brick masonry, cast-in-place concrete, precast, post-tension and steel frame, and are either free-standing structures or located within residential towers.
Parking garages in NYC experience heavy traffic, causing water infiltration and bringing in high levels of corrosive elements, such as salts. These result in a constant need for physical condition assessments and repairs. For busy, 24-hour parking garages, we phase the work when possible to maintain operations during construction. We achieve this by thoroughly understanding the restoration work, carefully planning, and working with the contractor to ensure proper site safety.
With our extensive portfolio of garage repairs and designs, we have determined the most cost-effective solutions for a wide variety of projects. We have also established assessment techniques proven to accurately define budgets.
EDG was selected for the façade restoration and roof waterproofing program for Montauk Manor, which began in 2008. This historic resort condominium hotel is the largest and tallest building in Montauk. It was built in 1926 by Carl G. Fisher and is a four-story, 200-room hotel in the Tudor Revival style. The building is exposed to extreme weather conditions due to its location on the Long Island Sound, where salt water from the ocean rapidly accelerates the deterioration of the façade and roof.
Investigation is always the first step to a successful restoration project. This includes performing careful due diligence to obtain all of the available information on the construction of the façade as well as the history of repairs. If we don’t have a clear picture, we probe prior to or during construction to determine the conditions. Proper repairs and waterproofing can only be designed when there is a thorough understanding of the existing construction.
We worked closely with the contractor for repairs so there were no surprises in material selection or cost, which was essential for performing the work within budget. Our experts are trained to work with contractors and collect feedback to ensure constructability. We continue to provide façade repair design and detailing for dozens of unique façade conditions, keeping the Manor free of leaks and maintaining the longevity of the Landmark.
The Metropolitan tower is an 80-story residential building in Manhattan. The existing roof was a concrete flat slab and topping slab for a window washing raceway. The hot-applied bitumen roofing had reached its usable life span and was leaking throughout. The scope of work included the investigation of the reported roof leaks, which ultimately led to the replacement of the topping slab and waterproofing membrane.
This was one of our most challenging roof replacement projects due to the building height and the topping slab, which made assessment of the roof membrane difficult. Proper design cannot be achieved by making assumptions, so we probed the roof to determine the cause and extent of the leaks. Through the probes, we discovered an improper pitch of the existing roof deck, which resulted in leaks at the perimeter.
With our understanding of the various types of waterproofing and by identifying all of the roofing requirements, our team selected the best membrane for the topping slab condition on this project. We then coordinated with a window washing rig consultant to ensure the replacement was performed correctly. For a complex project like this, we make sure that all parties, including the building management, designers, waterproofing manufacturer, window washing rig consultant, and contractor, work closely together for a successful project.
Winthrop Hospital is a 591-bed university hospital located on Long Island in Mineola, NY. Since 2004, this project has consisted of maintenance and restoration for five multi-story parking garages and three surface parking lots accommodating 3,500 vehicles. Each garage maintains a different building system, including steel frame, cast-in-place concrete, open-web joists, precast double tees and waffle slab construction. Work has included full and partial depth slab repairs, façade restoration, steel repairs, painting, control and expansion joint repairs, waterproofing, lighting system replacement, and reconfiguration of surface parking lots to increase capacity.
For this project, EDG provided structural analysis, condition survey and testing, design, bidding, construction administration, and job site supervision services. Investigation is always the first step to a successful project. This includes performing careful due diligence to obtain all of the available information about construction and repair history. By understanding every aspect of the project, we were able to provide considerable space, time and cost-saving solutions.
Value is at the center of everything we do, so we worked closely with the contractor for repairs. As a result, there were no surprises in material selection or cost, which was essential for performing the work within budget. Our experts are trained to work with contractors and collect their feedback, ensuring constructability.
A section of brick wall, approximately 60 ft. long and 30 ft. high had collapsed onto the city sidewalk. Fortunately, no one was injured in the collapse. EDG immediately responded to a call from the building’s management and was one of the first parties on site. Emergency response included coordinating sidewalk protection, assessment and reporting of the cause of the collapse, an investigation into the remainder of the wall, and design of the remediation program.
We worked integrally with the Commissioner of the NYC Department of Buildings and his team to investigate and determine the cause of the collapse. A report of our investigation was submitted within 24 hours and reviewed and approved by the Commissioner’s office.
Our investigation findings indicated extensive bowing and underlying deterioration of wall ties. Water had infiltrated the parapet coping and façade expansion joints, and there was improper drainage of the face brick. We performed an extensive investigation of the remaining walls to determine if any other wall sections were at risk of collapse. We then designed cost-effective remediation work to avoid reconstruction of the full length of the wall.
The building is an 18-story residential tower with a two-level parking garage below. The garage below this existing tower hadn’t received maintenance in a long time and was in extreme disrepair. EDG developed an extensive repair program and performed a feasibility study to determine if it was possible to replace one of the elevators with a vehicular ramp for faster access for the garage operator.
Our client had already had some design work performed and received bids from contractors prior to our involvement. They were given our name from a reference because of our experience as value-engineering specialists. We reassessed, looking to find the best repair method and products for the project. This often involves big-picture assessments, such as weighing the cost of full replacement against the cost of patch-work. For the new ramp, we made use of our surveying technology and understanding of building engineering and worked within inches to provide the ramp access.
We determined that the most cost-effective repair would be to replace the entire topside of the concrete slab, as opposed to a patch-style repair. Due to the volume of patch repairs that would be required, including the joint work, and the individual prep and piece-work, this replacement was a better repair and produced savings of nearly $400,000. With the ramp installation, we increased the value of the space to this operator significantly for minimal cost, providing a return on investment in a year and a half. Weighing cost vs. value is at the center of everything we do. All work, including the ramp and sidewalk waterproofing issues, was performed for the same amount as the original contractors bid for just the patch repair.
Located on First Avenue in the Upper East Side (East 84th Street), this 32-story building has a high visibility podium set back from the street on three sides. EDG was asked to perform both structural and architectural services in updating the aging brick façade. Our intent was to replace the façade and weathered storefront with a contemporary and timeless solution, using materials that complement the remaining building and upper tower.
Peeling back the original façade was a challenge, as there were a host of structural remediation issues which needed to be addressed before we could proceed with a new finish. With our years of experience in restoration and structural engineering, we addressed the issues and designed a new façade with a smooth stucco and limestone finish to enhance the existing building materials. We also designed a structurally-siliconed curtainwall system for the storefront, which provides a clean ribbon of glass for the retail tenants.
The new façade enlivens a very active corner in a high-density district and adds a new layer of elegance to the structure. The restoration and revitalization of the 160 feet of façade provide a new backdrop for the building’s occupants and surrounding neighborhood, enriching the plaza and promenade experience for residents, pedestrians and shoppers along the retail edge.

EDG was selected by the developer to create a master plan for Fun City Amusement. Located on approximately 13 acres, the site will be a sports and activities epicenter for families in the region. Given its size and scale, multiple locations in cities throughout the tri-state area have been explored. The design includes an indoor water park, YMCA, Olympic-size swimming pool, tennis courts, hockey rinks, basketball court, soccer field, river walk, educational center, 800-car parking garage, restaurants, atrium, support shops, and amenities.
We performed planning and conceptual designs for multiple sites, including site master planning, architectural direction, aid in the selection of the design team, and presentations to the municipal agencies.
We worked closely with the developer, local municipalities and community leaders to thoroughly understand the diverse needs of this extensive development. Multiple iterations of the master plan were prepared in response. We look forward to continuing this project when a new site is found.
Located in Chelsea, near the West Side Highway, this four-story building was on the market with great development potential and asked about addition feasibility. The client retained EDG to provided zoning and building code analysis, egress, architectural design, and structural analysis for potential future expansion.
We performed due diligence to create a full picture of the property and the existing building. We reviewed records from the Department of Buildings, including violation history, occupancy records, and previous filings. All of this information can greatly affect the value of the property. We then carefully reviewed the buildable floor area to determine the full development potential of the site.
With our extensive experience in practical cost estimating, we produced multiple development scenarios, including base repairs, an addition, demolition and reconstruction. In all options, we navigated complicated zoning and building code to fully utilize the site and deliver a much larger building. Ultimately, we gave the client a complete understanding of the existing property value and potential.
Located on the Upper West Side of Manhattan, this Landmark residential building is five stories high and has a cellar. EDG performed architectural design and structural engineering services for this gut renovation project (UWS Apartments). Searching for additional property value, we reviewed possible development scenarios, including recapturing unused floor area and the conversion to high-end residential apartments with an elevator. Ultimately, the renovation of all apartments was performed, recreational space was added to the cellar, and façade repairs were performed on the Landmark façade.
Renovating an existing building can be very challenging, given the unknown conditions behind walls and within ceilings and floors. A proper probe plan must be developed to assess the existing conditions, pinning down the costs, and avoiding changes during construction. The right contractors who have extensive experience in this type of work are required.
In addition to the full renovation of all apartments, we worked through all of the design issues to create two large recreation rooms in the cellar. We lowered the cellar floor a foot and a half to a ceiling height of 8 ft., greatly increasing the value of the ground floor units. Due to the renovations, the client’s return on investment is anticipated within two years.
Kidville is a national Daycare and Learning Center. EDG performed engineering, code and restoration work for three Kidville locations, including gut renovations, new elevators and stairs, extensive alterations, a new mezzanine, a building addition, and a full replacement of a Landmark façade.
In our initial project meeting, we performed value engineering to reduce the need for additional pile foundations, which would have delayed the schedule and brought the project significantly over budget.
We use smart design to save our clients money; not all consultants are able to provide that service. Prior to our involvement, an extensive foundation system of piles had been designed. After careful analysis, our value engineering deemed the system unnecessary, saving an estimated $500,000. Our cost-saving solution was the demolition of a heavy brick masonry ground floor, which was replaced by a lightweight wood floor. This allowed for an addition to the building without any foundation reinforcement.
To celebrate the Year of Italian Culture in the U.S., world-renowned designer Antonio Pio Saracino was commissioned to create a permanent public art project and a symbol of Italy. His work, “The Guardians: Hero and Superhero” stand proudly in the plaza at Three Bryant Park. We assisted friend and fellow architect Saracino in the structural design of the sculptures, pro-bono. The statues are each 13 ft. tall; one is constructed of danby marble and the other of mirror-polished stainless steel later called Bryant Park Heroes.
While we have designed many structures, including sculptures, this project was extremely unique. Saracino intended the many individual pieces (approximately 125) to appear disconnected. With all elements exposed to view, the structural supports could not be easily hidden, so we focused our attention on the assembly method.
EDG met the challenge by designing thin support rods and hiding welds with stainless steel covers. We even assessed and reinforced the sculptures for high wind and seismic-induced movement. With proper planning and a diligent team, we met the advanced deadline for installation and achieved the floating appearance Saracino designed.
We would love to take credit for this beautiful dealership and the beautiful cars, but that’s not what we do. What we do is make sure that money is not wasted on base construction and structure, so the client has enough money left in the budget for a stunning showroom. We were the structural engineers for this project, responsible for the expansion and extensive alterations to the dealership, including a new ramp for access to the second level, rooftop parking storage, column and bearing wall removals, and alterations for a new architectural façade.
With extensive experience in dealership and parking garage design, EDG has a strong understanding of vehicle storage space requirements and floor loading needs. Whether for new construction or an alteration, we look to design cost-effective solutions by exploring all options for the structure. We review all structural aspects of the project and offer more cost-effective alternatives to the architectural design. We value-engineer by ensuring the right approach is taken and by understanding the existing construction to best accommodate the alteration.
We redesigned the ramp in a more convenient and effective location, saving over $300,000 in unnecessary removals and relocation. This also gained valuable space for the showroom area and the vehicle storage area. Time and time again, through our value-engineering, we have found better, more cost-effective solutions, where the savings and increased value cover the cost of our fee.
Marcus Samuelsson, one of America’s most widely acclaimed chefs and winner of Top Chef Masters, brings his internationally praised signature cuisine to his Harlem Restaurant, Red Rooster. The new restaurant and event hall have a floor area totaling over 9,000 sq. ft. and include a kitchen on each level. We worked with noted restaurant interior designers on this project and provided project management, architectural design, code consultation and structural engineering services.
By researching and thoroughly understanding every aspect of the project, we provided solutions that saved considerable amounts of space, time and money. The client pays for the restaurant per square foot, so we made sure to maximize its potential by carefully space planning for the most seating areas. Filings were meticulously orchestrated to avoid delays in the project. Because the building was existing, we reviewed old code and new building code options to determine which gave us the optimal front of house space.
Although deemed impossible by other consultants, we obtained an approval for the use of the existing building vault space of almost 2,500 sq. ft., creating enormous value for a restaurant in need of space. Our mark was seen in nearly all aspects of the project, including review of the site for development prior to lease, aiding in selecting the team of consultants and contractors, layout design, management of all filings (including the special permit for the event space), and structural design for extensive interior alterations. We gained over 200 sq. ft. of additional front of house space, and provided constant monitoring of the critical path to the grand opening.
